Spring open closed high pressure safety valve，High pressure safety valve， safety valve

The spring-open closed high pressure safety valve ‌ 

is a device that relies on the elastic pressure of the spring to ensure a tight seal between the disc and the seat. When the pressure of the pressure vessel is abnormally increased, the high pressure will overcome the spring pressure of the safety valve, so that the locking device is pushed open, forming a pressure relief channel, so as to release the high pressure medium ‌

This kind of safety valve can be automatically closed after pressure relief without manual reset, suitable for LPG, air, water and other media equipment or pipelines with working temperature ≤300℃ ‌

Working principle

The working principle of the spring-open closed safety valve is based on the elastic pressure of the spring. When the system pressure exceeds the preset value, the pressure of the spring is overcome, the disc is opened, and the medium is discharged through the seat, thereby reducing the system pressure. When the pressure is reduced to the safe range, the disc automatically closes to ensure the system's tightness ‌

‌ spring micro-open closed high pressure safety valve is widely used in the following areas: ‌ 

‌ boilers and pressure vessels ‌ : In boilers and pressure vessels (such as gas and oil storage tanks), spring-loaded safety valves are used to monitor and control internal pressure. When the pressure exceeds the set value, the safety valve will automatically open to release the overpressure gas, protecting the safety of the equipment ‌

‌ Steam and refrigeration systems ‌ : In steam and refrigeration systems, spring-loaded safety valves provide pressure control to prevent excessive system pressure and protect equipment and pipelines ‌

‌ high pressure gas systems and steam pipelines ‌ : in these systems, spring-type safety valves are used as pressure relief channels to quickly release pressure and prevent pressure accumulation from causing danger ‌

‌ Chemical industry, petroleum and power industry ‌ : In the chemical industry, petroleum and power industry, spring-type safety valves are used to protect equipment in process and prevent production interruption or equipment damage caused by abnormal pressure ‌

‌ Environmental protection and safety ‌ : in the discharge of gas or liquid system, fully enclosed spring type safety valve can ensure that the medium does not leak, meet the requirements of environmental protection, while protecting the safety of operators ‌

‌ Marine and Aviation ‌ : On ships and aircraft, spring-loaded safety valves are used to ensure pressure safety in fuel, hydraulic and other critical systems ‌

‌ Building and heating ‌ : in hot water heating system, spring type safety valve can prevent overpressure caused by thermal expansion, protect pipes and equipment ‌
