Does the main pipe 100 points pipe 60 but valve 50 has an impact on heating?

There is an association, because his flux is not enough, you can choose, you can choose the valve of 65 for him to change it, because the pipeline is 60, you this.

Out of the order to 100 points pipeline 60, but the valve 50 corresponding to the heating should have another opposite, this should be a certain award for its warmth, so it is still a small piece of attention.

I just checked for you, this valve is universal and has no effect.

The valve is slightly smaller, but the impact on heating is negligible and can be ignored, as long as the pressure of the water is high, this is not to be considered.

Yes, it can cause severe circulation and is likely to cause the boiler to overheat and the heating to not heat up. Therefore, it should be overhauled or replaced in time.

In this case, it will reduce his traffic, but the impact is relatively not very large, so there is no problem in this regard.

1. Start with heating, when you first start heating, there are more sediments in the main pipeline, and the pipes here refer to the main pipes that have not yet reached the front of each household. If the valve is opened at this time, it is easy for dirt to enter the small tube, block the filter screen or deposit it in the floor heating pipe, resulting in poor heat exchange;

2. There are two purposes of closing the valve after the heating is stopped: one is to prevent the sediment from completely drying up in the water pipe and blocking the plastic pipe when there is no water, which is difficult to rush; The second is to prevent forgetting to close the valve when starting the pressure, and the dirty things come in again.

The valves commonly used in hot water boiler and steam boiler heating system are: globe valve, gate valve (or gate valve), butterfly valve, ball valve, check valve (check valve), safety valve, pressure reducing valve, pressure stabilizing valve, balance valve, regulating valve and a variety of self-operated control valves and electric control valves.

Among them, the globe valve: used to cut off the flow of medium, has a certain tempering performance, large pressure loss, and is commonly used in the heating system to cut off the flow of steam, and is used in the valve model"j"Indicates a globe valve.

Gate valve: used to cut off the flow of the medium, when the valve is fully open, the medium can pass through the general pipe without changing the flow direction, so the pressure loss is small. The regulation performance of the gate valve is very poor, and it is used in the valve model"z"Indicates a gate valve.

Check valve: also known as check valve or check valve, it allows the medium to flow in one direction, if the pressure behind the valve is higher than the pressure before the valve, the check valve will automatically close. There are many types of check valves, mainly including:

Lifting, swinging, etc. The lifting valve has a large pressure loss, so it is rarely used in the new heat exchange station system. Used in valve models"h"Denote.

Butterfly valve: by changing the angle of the disc to achieve adjustment and switching, because the disc is always in the middle of the flowing medium, so the resistance formed is larger, so it is rarely used. Used in valve models"d"Denote.

Safety valve: It is mainly used to relieve pressure when the medium is overpressurized to protect equipment and systems. In some cases, the micro-opening hydraulic relief valve has been modified to be used as a system pressure regulator.

There are often mainly globe valves (main gas valves, some use plunger valves, but their closing operation is inconvenient, so most of them use globe valves) sewage valves, and then the ball valve water level gauge, which must be used in each shift, and then the water supply system, including the valve safety valve on the water treatment system pipeline; Evacuation valves, etc., are used in smaller quantities.

The pressure of the steam boiler is up to several hundred MPa, and steam is sent out. It is mostly used in industry, and medium and high pressure are mainly used in thermal power plants. Strong completeness, high technical content, multiple units with automatic control, and large investment. The state has strict management of steam boilers, and there are many categories of compulsory inspection and annual inspection.

The pressure of the hot water boiler is below, and hot water is sent out. It is mostly used for life, with small investment and low management costs. Safe.

It is better to use cast steel gate valves.

You can just find the place where you bought the boiler at that time. When you buy indiscriminately, it will be troublesome if you don't match it.

Are you talking about a small domestic boiler or an industrial boiler?

The valve of the heating is a ball valve, which can be found on the heating pipe, and the valve in the picture is the valve of each heating branch.

Heating valve opening:

1. From the front of the heating valve, you can see that there is a letter "O" (see the figure below for the position), which is the abbreviation of the English word "open", which means to open. Note that there is also a counterclockwise pointing arrow near the letter "o", which means that the counterclockwise rotation opens the heating valve.

2. From the front of the heating valve, the other side can see a letter "S" (see the figure below for the position), which is the abbreviation of the English word "shut", which means to close, pay attention to check, you will also see a clockwise arrow near the "S", and the rotation in the direction pointed by this arrow will close the heating valve.

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

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

When you want to use the wall-hung boiler to turn on the heating in winter, the hot water heating is used at the same time, and the four valves are opened in this way, and the buttons are in this way. The second one on the left side of the diagram is the water supply valve, and there is another water filling valve next to it (indicated in Figure 7 below). Please refer to the instructions for the water filling procedure in detail, and close the water filling valve when the pressure is reached.

It is recommended to use a globe valve for gas valves, which are very airtight.

Interception valves for high-pressure steam, or gate valves, are used. There is no problem technically, the instrument design often does not consider this problem, only the actual solution on site, feasible. Of course, when I say high pressure, I mean that your boiler pressure is more than 30-40 kg.

Temperature 200 or more. Depending on your boiler pressure.

1: Maybe the quality of the valve is too poor, and our factory uses this very little, 2: If it is too frequent, try to change it to a new one.

The wall-hung boiler heating valve is open which diagram, because I can't see what kind of diagram from your literally, so you don't know which way to answer this question, so I can't help you, I hope you understand.

The heating valve of the wall-hung boiler is open for water inlet and outlet, and at the radiator, the valve for water inlet and outlet must be opened.

You can read one, the manual is fine, and there are all of them.

All you have to do is open the valves that bring it out.

This is the mentally retarded question asked by the standard mentally handicapped person.

The following four switches are all used for nothing, do you think someone can tell you whether it should be turned on or off?

The exact purpose of these four valves should be clarified first, combined with the actual flow and circulation needs of hot water in the heating pipeline, to determine which valve should be closed and which valve should be opened.

You can also find the product installation instructions given by the gas boiler manufacturer to see the relevant instructions inside.
