Stainless steel check valve is an automatic valve, whose main function is to prevent medium backflow and has the following important functions:
1 Preventing safety issues caused by medium backflow
Function in the water supply and drainage system
In the water supply system of a building, check valves are installed at the outlet of the water pump. When the water pump stops working, the check valve can prevent water in the pipeline from flowing back to the pump under the action of gravity. For example, if the water supply pump of a high-rise building stops running without a check valve, the water may flow backwards, causing the impeller of the pump to reverse under the impact of the backflow water flow. This not only damages the mechanical components of the water pump, such as impellers and bearings, but may also damage the sealing device of the water pump, causing problems such as water leakage.
In the drainage system, check valves can prevent sewage from flowing back. For example, in some basement drainage pipes, if sewage flows back, it may cause the basement to be submerged by sewage, resulting in serious environmental pollution and equipment damage. Check valves can prevent sewage from flowing back from drainage pipes into other areas inside the building.
The role in industrial pipeline systems
In the pipeline system of the chemical industry, many chemical media have corrosive, toxic, or flammable and explosive characteristics. Check valves can prevent the backflow of these hazardous media. For example, in a pipeline system transporting flammable liquids such as gasoline, if there is a backflow of the medium, it may allow the liquid to enter other equipment, causing a fire or explosion accident. The check valve ensures that the medium can only flow in the predetermined direction through its one-way conductivity, ensuring the safe operation of the entire pipeline system.
2 The role of ensuring the normal operation of the system and energy conservation
Guarantee for equipment operation
In some thermal systems, such as steam pipeline systems, check valves can prevent steam backflow from causing damage to equipment such as boilers. When the boiler stops supplying steam, the check valve can prevent the steam in the steam pipeline from flowing back to the boiler, avoiding abnormal pressure rise inside the boiler and protecting the structural integrity of the boiler. At the same time, it can also prevent steam from flowing back in the pipeline and causing water hammer phenomenon. The phenomenon of water hammer is caused by rapid pressure fluctuations caused by steam backflow, which can have a huge impact on pipelines and equipment. Check valves can effectively avoid this situation.
The role of energy conservation
In some circulating water systems, check valves can improve energy efficiency. For example, in the cooling water circulation system of an air conditioning system, a check valve can ensure that the cooling water circulates in the correct direction. If the cooling water flows back, it may cause a decrease in the cooling effect of the cooling tower, requiring the entire air conditioning system to consume more energy to achieve the same cooling effect. By installing check valves, the normal circulation of cooling water can be maintained, ensuring the efficient operation of the air conditioning system and achieving energy-saving goals.
