What is a hammer check valve?

2023-05-06

What is a hammer check valve?

A hammer check valve is a type of check valve that is designed to prevent water hammering in pipelines. Water hammer is caused by momentum changes when water flow is abruptly stopped or redirected and can cause significant damage to pipelines and connected equipment. Hammer check valves use a weighted disc to close and prevent water hammering rapidly and are often used in high-pressure piping systems where the water hammer is a potential risk.

The heavy hammer check valve is mainly used in the water supply system. It is installed vertically in the pipeline. It is lifted by the pressure difference in the system and the weight of the valve disc itself. It can automatically prevent the reverse flow of the medium water and ensure the normal operation of the pipeline.

What are the advantages of a heavy hammer check valve?

1.Prevents water hammer:

A heavy hammer check valve is specifically designed to prevent water hammer, which can cause significant damage to equipment and pipelines.

2.Quick response time:

The valve responds quickly to changes in flow and pressure, closing rapidly to prevent water hammer.

3.High working pressure:

The working pressure of various materials can reach 1.0Mpa at room temperature.

4.Wide operating temperature:

The operating temperature of PPR is -20°C~+70°C, the operating temperature of PP is -20°C~+95°C; the operating temperature of GFRPP is -20°C~+120°C.

5.Good impact resistance:

PPR and GFRPP have high mechanical strength and impact resistance.

6.Small liquid flow resistance:

The inner wall of the product is smooth, the friction coefficient is small, and the conveying efficiency is high.

7.Excellent chemical performance:

This product is non-toxic, tasteless, acid and alkali resistant, corrosion resistant, and has a wide range of applications. Small corrosive liquid pipelines and equipment; PP and GFRPP are mainly used for liquid (gas) circulation of highly corrosive strong acids, strong alkalis and mixed acids.

8.Easy installation and good sealing:

This product is light in weight, adopts bonding or welding, complete pipe fittings, easy construction, good sealing, and low labor intensity.

What are the working conditions for heavy hammer check valves?

Heavy hammered check valves are typically designed to operate under specific working conditions. The working conditions for heavy hammer check valves include the following:

1.Operating pressure:

Heavy hammer check valves are typically designed to operate in high-pressure applications.

The maximum operating pressure that the valve can handle will depend on the specific design and construction of the valve.

2.Fluid type:

The type of fluid the valve will handle is an important consideration when selecting a heavy hammer check valve. The valve will need to be constructed from materials that are compatible with the fluid, and the valve performance will need to be tested to ensure that it can handle the specific fluid.

3.Operating temperature:

The operating temperature of the fluid will also need to be considered when selecting a heavy hammer check valve. The valve will need to be constructed from materials that can withstand the temperature of the fluid.

4.Flow rate:

Heavy hammer check valves are suitable for applications with high flow rates. The valve design will be determined by the specific flow rate requirements.

5.Installation position:

The valve installation position is also important. Heavy hammer check valves should be installed in a position that allows for proper operation. The fluid flow direction should be clearly marked to ensure that the valve is installed in the correct orientation.
