After Reading This Article, You Will Understand The Main Advantages Of Pulse Safety Valve
Mar 26, 2022
The mechanism characteristics of pulse safety valve mainly include:
1. The soft sealing of the valve seat ensures the good sealing of the safety valve before and after take-off.
2. The working pressure is allowed to approach the set pressure of the safety valve.
3. Small overpressure can make the main valve of the safety valve quickly reach the full opening state.
4. The action performance and opening height of the safety valve are not affected by the back pressure.
5. The opening and closing differential pressure is adjustable.
6. The non flowing structure design of the pilot valve reduces the discharge of harmful media and environmental pollution.
7. The set pressure of the safety valve can be detected online.
The main advantage of the pulse safety valve is that it changes the direct action of the spring into the indirect action of the pilot valve, which improves the action sensitivity. Moreover, the main valve adopts the sleeve piston type and double sealing seat structure, which has high action accuracy, good repeatability, fast reseating, no leakage, can discharge with high back pressure, long service life, stable and reliable operation. It can also be adjusted online. After repeated startup and tripping discharge, it can still return to its seat automatically and close tightly, Convenient operation and maintenance.
The pulse safety valve is convenient for on-site maintenance and repair.
The good seat tightness of pulse safety valve will minimize the seat leakage, while the design of spring safety valve will further damage the sealing surface due to leakage, resulting in more serious leakage. Because the pulse safety valve adopts soft sealing parts, it does not need frequent maintenance, and the replacement of soft sealing parts can greatly reduce the maintenance cost compared with the replacement of metal parts (springs, nozzles, bellows, etc.) of spring safety valve, so as to reduce the long-term use cost of users.
Its disadvantage is that its reliability is related to the main valve and pilot valve. Its action is not as fast and reliable as the direct acting safety valve, and its structure is complex.
