Residual pressure valve hammer

The residual pressure valve weight is an important part of the residual pressure valve. Its main function is to maintain the normal working state of the residual pressure valve and control the opening and closing of the valve by moving up and down. The following is a detailed analysis of the residual pressure valve weight:

1. The role of the residual pressure valve weight

Control valve opening and closing: When the water supply pressure is normal, the residual pressure valve weight will close the valve to prevent sewage backflow; when the water supply pressure is insufficient, the valve opens to ensure that the water can flow normally.

Maintain system stability: The residual pressure valve weight ensures that the residual pressure valve can work stably under different pressure conditions through its weight and movement, thereby maintaining the stability and safety of the entire water supply system.

2. Composition and structure of the residual pressure valve weight

The residual pressure valve weight is generally made of cast iron or cast steel and other materials, and is heavy to ensure its stability and firmness in the water flow. It is usually located at the water inlet of the residual pressure valve and is connected to the valve body through a spring or other connecting mechanism.

3. Working principle of the residual pressure valve weight

Normal water supply state: When the water supply pressure is normal, the residual pressure valve weight is subjected to downward gravity, closing the valve tightly to prevent sewage from flowing back into the water supply system through the pipe.

Insufficient water supply pressure state: When the water supply pressure is lower than a certain value, the pressure on the weight decreases. At this time, the spring or other reset mechanism moves the weight upward, the valve opens, and water is allowed to flow through, thereby ensuring that users can use water normally.

4. Maintenance and care of the residual pressure valve weight

Regular inspection: Regularly check the weight, connection mechanism and sealing performance of the residual pressure valve weight to ensure its normal operation.

Cleaning and maintenance: Keep the residual pressure valve and its surrounding environment clean and hygienic to avoid clogging or affecting the movement of the weight.

Timely maintenance: When the residual pressure valve weight is found to be damaged or faulty, it should be repaired or replaced in time to ensure the normal operation of the system.

5. Application scenario

The residual pressure valve weight is widely used in water supply pipeline systems, especially in situations where it is necessary to prevent sewage from flowing back and contaminating drinking water. For example, in public buildings such as high-rise buildings, hospitals, and schools, the role of the residual pressure valve weight is particularly important, as it can ensure the safety and stability of the water supply system.

In summary, the residual pressure valve weight is an important part of the residual pressure valve, which controls the opening and closing of the valve by moving it up and down, thereby maintaining the stability and safety of the entire water supply system. During use, it needs to be inspected, cleaned, and repaired regularly to ensure its normal operation.
