Upgrade to high sensitivity steam pressure relief valve

Upgrade sensitivity, yongjia county, steam pressure relief valve is the valve door co. , LTD. , from the relief valve. The commonly used at home and abroad. High sensitivity steam pressure relief valve belongs to pilot live game type pressure relief valve. Consists of two parts, the main valve and pilot valve. The main valve is mainly composed of valve seat, the main valve plate, piston, spring and other parts. Pilot valve is mainly composed of valve seat and valve disc, diaphragm, spring, adjusting spring and other parts. By adjusting the adjusting the spring pressure setting outlet pressure, the use of diaphragm sensing outlet pressure changes, through the pilot valve opening and closing drive piston regulate the flow of the main throttle valve parts area, the size of the reduced pressure regulator function. High sensitivity steam pressure relief valve series products on the basis of ordinary pressure relief valve to do the following improvement, increased the piston area, changed the structure of throttling, changed the seal form, improve the guide valve structure and regulation of the spring form, so as to improve the performance of the product from the following aspects. 1, improve the sensing performance of outlet pressure change, improve the sensitivity, greatly reduces the due to changes in upstream pressure, pressure caused by the change in the flow deviation. 2, improve the streamline distribution, reduces the noise. 3, improve the structure of sealing surface, extend the life of the sealing surface. High sensitivity steam pressure relief valve is mainly used for pipe line, apply to the change of inlet pressure, flow rate change of steam pipeline.
