How to open and close the temperature control valve for heating? Heating main valve switch

The heating valve has the direction of opening and closing, which is often indicated by the letter Os.

The heating inlet valve is marked with "O" for opening valve, abbreviation for "open" in English, and "S" for closing valve, abbreviation for "shut" in English. The copper ball door is generally moved along the pipeline for the valve in the open position, and the difference between the moving hand and the pipeline is 90 degrees for the valve in the closed position.

The valve that rotates the handwheel to open and close is to turn to the right to close the valve, and to the left to turn to the end to open the valve.

Open the valve clockwise.

Turn the handwheel, turn the handwheel counterclockwise when closing, and rotate it in place according to the opening and closing indication marks. Radiator.

Do not arbitrarily change the position, and do not release water from the system at will, if the hot water is lost, the water temperature in the pipe network will drop rapidly, resulting in a decrease in indoor temperature. If the valve is found to be faulty, it should be stopped immediately, the cause should be found out and the fault should be removed.

Extended information: Thermostatic valve construction and principle.

The user's room temperature control is achieved by the radiator thermostatic control valve. The radiator thermostatic control valve is composed of a thermostatic controller, a flow regulating valve and a pair of connecting parts, in which the core component of the thermostatic controller is the sensor unit, that is, the temperature bag.

The temperature package can sense the volume change due to the change of the surrounding ambient temperature, drive the valve core of the regulating valve to produce displacement, and then adjust the water volume of the radiator to change the heat dissipation of the radiator.

The set temperature of the thermostat can be adjusted manually, and the thermostat will automatically control and adjust the water volume of the radiator according to the set requirements to achieve the goal of controlling the indoor temperature.

If you have a heating at home, you need to know some knowledge about the heating temperature control valve, which can adjust the flow rate of the heating and control the temperature regulation, and adjust the flow rate by adjusting the temperature control valve to make the indoor temperature reach the most suitable temperature value.

Surface-mounted radiator temperature control valve refers to an automatic control valve installed on the radiator.

Working principle: By controlling the flow of hot water into the pipe of the heat exchanger, the purpose of controlling the temperature of the equipment outlet is achieved. When the load changes, the flow rate is adjusted by changing the opening degree of the valve to eliminate the effect of load fluctuations and restore the temperature to the set value.

1. Adjust the temperature.

As the name suggests, the main function of the surface-mounted radiator is to adjust the temperature, the temperature control valve can control the amount of hot water into the heating pipe, the more hot water flow, the higher the temperature, and the lower the flow rate, so as to control the temperature.

2. Separate room heating.

When a room is unmanned for a long time, the user can close the temperature control valve of the radiator in the room, which can play the role of sub-room heating.

3. Balance water pressure.

At present, the temperature control device is no longer satisfied with the simple temperature control function, but pays more attention to the flow balance of the overall heating system, so as to balance the water pressure and provide users with a more comfortable living environment.

4. Save energy.

According to the requirements of room temperature, the temperature can be adjusted and set by using a temperature control valve. This ensures a constant room temperature and avoids unbalanced water volume in the pipes and uneven room temperature in the upper and lower floors of a single-pipe system. At the same time, through constant temperature control and economic operation, it can not only improve the comfort of indoor thermal environment, but also achieve energy saving.

Summary. From the front of the heating valve, you can see that there is a letter "o", which is the abbreviation of the English word "open", which means to open, and there is a counterclockwise arrow near the letter "o", that is, it rotates counterclockwise to open the heating valve.

2. From the front of the heating valve, a letter "S" can be seen on the other side, as can be seen in the figure below, it is the abbreviation of the English word "shut", which means that it is closed, and you will also see a clockwise arrow pointing near the "S", and the heating valve will be closed if you rotate in the direction indicated by this arrow.

3. When the heating valve is opened, look at the valve from the front and rotate it in a counterclockwise direction to open the heating valve.

4. After using this method to open the valve, when the heating is not hot, you must check the room heater to open the valve and rotate it in a counterclockwise direction.

Kiss. Which one is the heating valve.

Red pro. It's all red.

Yes dear.

Here's how to unscrew the heating valve switch:

1. Usually if the regulating valve on the heating is a ball valve, it is opened when the handle is in a straight line with the pipe.

2. If the handle of the heating valve is a handwheel, rotate it to the right to open.

3. If the valve has been opened and the radiator is still not hot, it is caused by the air in the radiator pipe or radiator. In this case, all you need to do is open the exhaust valve on the radiator to empty the air.

What should I do if the radiator valve can't be unscrewed?

1. Make sure you have made a mistake in the direction, twist to the left, counterclockwise is the on, if you mistakenly take the closed direction as open, it will only get tighter and tighter.

2. If you tighten it too tightly last time and find that you can't screw it by hand, you should rely on a tool to open the valve, use a wrench or vice, and then clamp the valve to the counterclockwise direction, which can save a lot of effort.

3. If the radiator has not been used for a long time and is rusty, the air release valve is a little rusty, and the hand cannot be unscrewed. Therefore, before screwing, you should drip some lubricant, put the lubricant into the valve of the radiator, and then use a wrench to open it. It's just that the air release valve is a little rusty, and it's not used in the summer and autumn.

4. When screwing, do not use brute force to open, which will backfire and avoid breaking the radiator valve, which will be more troublesome when this kind of situation occurs.

How to open the heating valve:

Tool: Heating valve.

1. Open the entrance valve, which is generally controlled by the heating unit. If you don't owe heating bills, it will be turned on naturally, and if there is no sound of water filling in your own pipeline, you can contact the heating station in the community. Open the indoor pipeline valve, and generally set up the main valve at home when installing heating.

Locate the tubing valve location.

2. Distinguish which valve is water inlet and which is back water. Turn the inlet valve counterclockwise and open it completely by placing the handle of the valve parallel to the pipeline. Then open the birth valve in the same way.

If you can't tell the difference between the inlet and outlet valves, you can also open either one first and open the other.

3. If it is geothermal, open the inlet and outlet valves of the water separator at the same time. The corresponding upper and lower pipes are water inlet and water outlet, if the valve handle is horizontal, it should be rotated 90 degrees counterclockwise and the position parallel to the pipe is opened.

4. After all are opened, check whether there is water leakage, and close the water inlet valve in time if there is. If not, open the windproof valve of the water separator or radiator and drain the air inside so as not to affect the quality of the heating.

Precautions for using heating

1. Be sure to ensure that the surrounding area of the radiator is ventilated, and the air must be in a state of circulation, because the radiator depends on radiation, as well as convection heat dissipation, if the heat dissipation is not good, then it will affect the service life of the radiator. Also, remember not to pile large objects around the radiator to avoid uneven temperature or unheated rooms.

2. Some friends will install radiators in every room at home, and they must remember to use them regularly, because if they are not used for a long time, the radiators will be corroded or oxidized, and they are prone to water leakage when they are used next time. The temperature of the room can be controlled at about 18 degrees Celsius, so that it will not consume too much energy and can also save everyone's living costs.

3. Do not add a cover outside, although it will look more beautiful, but it will affect the heat dissipation, which will also affect the heating effect.

The first step is to find the location of the temperature control valve for the radiator.

The second step is to adjust the opening and closing degree of the temperature control valve according to your needs.

In the third step, if the temperature control valve is adjusted to be parallel to the pipeline, then the pipeline is completely open, and if the temperature valve is adjusted to be perpendicular to the pipeline, then the pipeline will be completely closed.

The fourth step, the heating principle of the radiator is completed by heating the water, and then dissipating the heat through the radiator, if the temperature control valve is opened to the maximum, the water flow is the maximum, that is, the temperature is the highest.

The fifth step is to open the temperature control valve to the minimum, that is, the water flow is the smallest, and the temperature is the lowest, so finally adjust the temperature control valve to a suitable angle according to the actual situation, such as at a 45-degree angle with the pipeline.

When the load changes, the temperature control valve adjusts the flow rate by changing the opening degree of the valve to eliminate the effect of load fluctuations and restore the temperature to the set value.

The controller has the function of PI and PID adjustment, precise control, multi-loop control, and various functions, which can realize the control of fluid flow, pressure, differential pressure, temperature, humidity, enthalpy value and air quality. The actuators are available in electromechanical and electro-hydraulic versions, with manual and automatic adjustment functions, sensitive adjustment, high shut-off force, and adjustable flow characteristics (linear equal percentage).

Electro-hydraulic actuators with auto-reset protection in case of power failure, can receive signals from 0-10V or 4-20mA and have valve position feedback. The valve body is a flow control valve, which is suitable for circulating pipeline chilled water, low-pressure hot water, domestic hot water, high-pressure hot water, seawater, hot oil, and steam adjustment linearity, large adjustable ratio, tight sealing, high temperature resistance, and anti-cavitation.

A1Try not to wrap the radiator when installing the temperature control valve, because the heat dissipation function of the radiator will be limited, resulting in a slow rise in room temperature and increased heat loss.

2.If there is a leak in the radiator during use, it must be repaired in time, otherwise the leaking radiator will increase the heat loss.

3.Due to the stagnation of water circulation caused by the converging surface in the pipe, which affects the heating effect, the tail of each group of radiators should be installed according to the dynamic air release valve when installing the temperature control valve, and the action should be small when deflating to prevent it from being broken, and the air release valve should be tightened in time when the water flows out.

Methods for regulating the flow rate of each room with a thermostat:

1. If you want to save heat costs, the root is to save heat, and there are two factors to save heat: one is to improve the awareness of energy conservation and actively adjust, and the other is to adjust scientifically and reasonably. Only in this way can you save heat and save heat bills.

2. During the heating period, the room temperature of our bedroom, living room and bathroom is best guaranteed to be at 18, and the main equipment for adjustment is the temperature control valve, which has a digital scale on the valve, and the larger the number corresponding to the adjustment time, the higher the temperature in the room. It is best to follow the following two methods of adjustment:

Adjust by time period: If the family is all office workers or school students, there is no one at home during the day. When the outdoor temperature is high every day, you can properly adjust the temperature control valve when you leave the house to reduce heat consumption.

(1) In the vertical single-pipe downstream system, because the water volume of the previous group of radiators flows through the next group of radiators, and each group of radiators is located on different floors, the radiator temperature control valve cannot be installed. Consideration could be given to retrofitting the system to a vertical single-pipe spanning system, which allows for the installation of a temperature control valve or a manual control valve with better regulation performance in front of each set of radiators.

2) In the vertical double-pipe downstream system, due to the problem of vertical imbalance, the radiator temperature control valve with preset function can be installed during the system transformation. The so-called pre-setting function is a device with a pre-set initial resistance on the body of the thermostat valve, through which the initial resistance of the thermostat valve can be set, and the initial resistance set between different floors is different, which can solve the problem of vertical misalignment to a certain extent. However, the following work needs to be done in the practical use of this method.

Designers should do a more specific hydraulic calculation. During installation, the construction party should carefully compare the water resistance streamline diagram provided by the supplier and adjust the temperature control valve to the correct preset position. After the water supply is in operation, it can be adjusted individually according to the specific situation.

Because the double-pipe system adopts a high-resistance temperature control valve, and the pre-set adjustment further reduces the valve opening, there are high requirements for the heating water quality, otherwise it can easily cause blockage.

2. According to the temperature displayed on the left side of the thermostat display box, the right side is the set temperature, and choose to press the up or down button to set the set temperature to 2-3 degrees higher than the room temperature.

3. Press the mode button to select the manual mode.

4. After the operation is completed, keep working continuously for 48 hours.

5. Every 24 hours in the future, the thermostat will be raised by 2-3 degrees until the room temperature meets the requirements (generally set at 18 degrees -20 degrees).

6. The thermostat designed and used in the floor heating system is a dual-temperature dual-control type, in addition to the thermostat body is provided with a temperature sensor for indoor temperature, a ground temperature sensor is added to control and protect the ground temperature. The factory is set to 45 degrees, if the ground decoration material is tiles, the normal situation can be adjusted without adjustment, does not affect the use.
