Spiraxsarco pressure reducing valve refers to a valve used in the steam system pipeline to reduce the inlet pressure of the steam pipeline to a required outlet pressure through adjustment, and automatically maintain a stable outlet pressure by relying on the energy of the steam medium itself
The outlet pressure of the main valve will not change due to the change of the inlet pressure, and its outlet pressure will not change due to the change of the outlet flow of the main valve
It is applicable to industrial water supply, fire water supply and domestic water pipe network systems
Speasak pressure reducing valve is mainly used for gas pipeline, such as air, nitrogen, oxygen, hydrogen, coal gas, liquefied gas, natural gas, etc
UK speasak 17/25/27 series pilot valve diaphragm type regulating valve can effectively control steam temperature and / or pressure through diversified combinations of the same main valve and different valves of different models
The design and manufacture of speasak 17/25/27 series regulating valves are completely based on the needs of users
Its diversified combination is comparable to that of no other regulating valve in the industry
In order to realize the independence and economy of multi-objective control equipment, multiple controls can be combined on the same main valve
Whether it is temperature control, pressure regulation or both, it can achieve rapid response, accurate control, safety and reliability
Meanwhile, all parts of 17/25/27 series regulating valves can be disassembled for inspection or maintenance without moving the main valve body in the pipeline
Correct type selection, installation and maintenance can ensure its long-term trouble free operation
Working principle of spike 17/25/27p pressure reducing valve: when the pilot valve spring is in free state before starting, the main valve and pilot valve are closed
The pilot valve is opened by spring force, the steam enters the main diaphragm chamber through the pilot valve, and part of the steam flows out through the control hole
When the steam flowing into the pilot valve is greater than the steam flowing out of the control hole, the control pressure in the main diaphragm valve increases, and the main valve is opened
As the steam flows through the main valve, the increment of downstream pressure is fed back through the induction pipe and acts under the pilot valve diaphragm to balance the spring pressure on the upper part of the diaphragm, so as to make the pilot valve close and throttle, maintain the pressure in the main diaphragm, and control the opening of the main valve to deliver an appropriate amount of steam
The downstream pressure can be changed by adjusting the spring on the pilot valve diaphragm
UK spiraxsarco pilot type diaphragm pressure reducing valve 25p series pressure reducing valve, dp27 series, dp143 series and dp163 series 25p pilot type diaphragm pressure reducing valve are divided into: 25p, 25t, 25te, 25pe, 25pt and 25pte
