What valve can be added to the water inlet of the fire pool to control the water level automatically

Fire poolThe water inlet can be controlled by a float valve, and the water level will be closed naturally, and the water level will automatically enter the water. A valve consisting of components such as a toggle arm and a float can be used for automatic control.

The liquid level of a water tower or pool. It has the characteristics of simple maintenance, flexible and durable, high accuracy of liquid level control, water level is not disturbed by water pressure, and the opening and closing are tight and no water leakage.

How the float valve works

The float always has to float on the water, and when the water is **, the float also rises. If it floats up, it drives the connecting rod to rise as well. The connecting rod is connected to the valve at the other end, and when it rises to a certain position, the connecting rod supports the rubber piston pad to close the water source.

When the water level drops, the float also drops, and the connecting rod drives the piston pad to open.

The float valve regulates the amount of liquid supplied by controlling the liquid level. Flooded evaporator.

The liquid level is required to maintain a certain height, and the float expansion valve is generally suitable.

The working principle of the float valve is to control the opening or closing of a valve by the lowering and raising of the float in the float chamber by the liquid level.

The float chamber is placed on the side of the flooded evaporator, and the upper and lower balance pipes are communicated with the evaporator, so the liquid level height of the two is the same. When the liquid level in the evaporator drops, the liquid level of the float chamber also drops, so the float falls, and the valve opening degree increases by lever action, and the liquid supply is increased. Vice versa.

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

The drawing of this water inlet control pipe can only see the water level height, and when the water cannot be seen in the control pipe, it is necessary to replenish the water. A float valve can be installed in the tank to achieve automatic control.

A check valve should be set up to discharge the water in the roof fire water tank to prevent the water from flowing back into the water tank after the fire pump is started. The water supply of the tank should be equipped with a float valve or a hydraulic water level control valve for automatic water replenishment.

The roof fire water tank needs to install a check valve to prevent the water tank from entering the water after the fire pump is started, and the water tank water supply is equipped with an automatic float valve or hydraulic water level regulator.

The process of adding water to the tank is a very important process for the management of fire-fighting equipment. First of all, the fire pool is an important part of fire protection engineering, which is mainly used for fire emergency rescue and emergency response to emergencies such as fire return to the shed. Secondly, the regular inspection and maintenance of the fire pool is very critical, and the technical scheme of the liquid level signal control pool water addition can ensure that the water level of the pool is within a certain range, and ensure the adequacy and reliability of the fire water.

In practical application, the method of controlling the water filling of the pool with the liquid level signal of the fire pool generally includes measures such as cables and float switches. These devices will send signals according to the liquid level to control the start and stop of the pump, so as to achieve the purpose of maintaining the water level balance of the pool. At the same time, in the process of adding water to the fire pool, it is necessary to consider the disinfection and sterilization of water, as well as the safety of water quality, etc., to ensure that the water quality of the fire pool meets the requirements of fire water.

All in all, the water filling of the fire pool is a technical measure that plays an important role in the fire emergency treatment. The effectiveness and reliability of fire-fighting equipment is an important means to ensure public safety and prevent fires. <>

How does the inlet control pipe of a fire pool (water tank) work?

Hello dear, the working principle of the water inlet solenoid valve is to appear on the connection between the solenoid valve and the high-pressure water pump, which is generally connected on the computer board, after the normal solenoid valve is opened, the high-pressure water pump shoots off the normal operation; If, after closing the solenoid valve, the high-pressure water pump also stops rotating, then it stops working properly. In the process of energizing the solenoid valve, because the solenoid coil will produce the corresponding magnetic force, then the closing and closing components will be lifted from the valve seat, and then the valve will be opened, so as to control the movement of the mechanical device. When the electromagnetic force is turned off, the electromagnetic force disappears, and the normal operation stops.

I hope I can help you.

Kiss! Hello, happy to answer your <>

The level pipe that is pro-fire water needs to be equipped with a drain valve. The diameter of the inlet pipe of the fire pool should be calculated and determined, and should not be less than. The diameter and flow rate of the inlet pipe wheel of the fire pool should be determined according to the pressure of the municipal water supply pipe network or other water supply pipe network, the diameter of the inlet pipe into the household, the diameter of the water inlet pipe of the fire pool, and other water consumption in the event of a fire.

3。Valves with indicating opening and closing devices should be set on the inlet and outlet pipes of the fire pool. 4。

The high-level fire water tank is filled with water for 8 hours, and the diameter of the inlet pipe should not be less than DN32, and the liquid level valve or float valve should be set up with a tung burner. 5。The overflow water level at the lowest point of the inlet nozzle should not be less than 100mm, and should not be greater than the void.

When a domestic water supply system is employed, the inlet pipe should not flood the outflow. The lowest point of the drinking water pool (box) inlet is higher than the overflow edge should be equal to the diameter of the inlet pipe, which can be between 25. When replenishing water to the fire pool, the lowest point of the water inlet should not be less than 150mm above the overflow edge.

Hope mine can help you <>
