The difference in function of four different pressure valves
Self-operated pressure regulating valve (hereinafter referred to as pressure valve) is an energy-saving product that does not require external energy and only relies on the pressure change of the regulating medium to automatically adjust the pressure. It has comprehensive functions of measurement, execution and control. It is widely used in petroleum, chemical, metallurgy, light industry and other industrial sectors as well as urban heating and heating systems. This product can be used in pressure control devices for non-corrosive media such as liquid, gas and steam with a maximum temperature of 350°C. Pressure reducing valve, safety valve, pressure regulating valve, and pressure relief valve are all pressure valves, mainly because of their functional differences.
The pressure reducing valve is a device that reduces the medium with high pressure to the medium with low pressure. The characteristic of this valve is to keep the outlet pressure and temperature within a certain range when the inlet pressure is constantly changing.
Safety valve is a valve used to prevent boilers, pressure vessels and other equipment or pipelines from being damaged due to overpressure. When the pressure is slightly higher than the normal working pressure, the safety valve is automatically opened to reduce the pressure. When the pressure is slightly lower than the normal working pressure, the safety valve automatically closes, stopping the discharge of fluid and maintaining the seal.
A pressure regulator valve is a device that keeps the medium in an area within a certain pressure range.
The difference between and the pressure reducing valve:
Reducing valve: No matter how the inlet pressure changes, the outlet pressure will be reduced to the rated value to reduce the pressure.
Regulator valve: maintains a constant upstream pressure regardless of changes in downstream pressure and demand.
Safety valve and pressure reducing valve are two types of valves, which are special valves. Among them, the safety valve is a safety venting device, which is a special valve, which only acts when the working pressure exceeds the allowable range, and plays a protective role in the system. The pressure reducing valve is a process valve, which can decompress the high-pressure flow to meet the pressure requirements of the post-system, and its working process is continuous.
The pressure relief valve is mainly used in the case of excessive pressure. When the pressure is greater than the set value, the valve inner piece is pushed open to release the pressure in time. After the pressure is reduced, it returns to the original position, which is not much different from the safety valve. It is mostly used for liquid, and safety valve is mostly used for gas and steam.
Guangdong Jinshang Intelligent Electric Co., Ltd. has continuously reformed and innovated on the basis of fully introducing and absorbing foreign advanced technology, and has successfully developed and produced valve series products for the core system of gas appliances, which are widely used in outdoor ovens, heaters, wall-hung boilers, gas appliances, etc. at home and abroad. On many products such as ovens, the company has always implemented the IS09001 quality management system and strictly implemented the "7S" management standard.
