When the pipeline medium pressure exceeds the pressure value, the auxiliary valve to open, the media along the catheter into the main valve and open the main valve spring A27H inching valve, the media pressure increased reduced. Emissions valve depends on the caliber of the seat and the valve opening height, can also be divided into two types: Weiqi open seat height is the inside diameter (1/20) - (1/40), the entire Kai is (1/3) - (1/4). Conventional safety valve used in the case of fixing the additional back pressure valve, when the pressure after the opening adjustment test (in this case the back pressure is atmospheric pressure), the setting value should be subtracted from the required opening pressure additional back-pressure value. Valve Co., Ltd. Shandong Everbright valve manufacturer specializing in the production, welcome new and old customers to order our products! Corporate culture is the soul, is an inexhaustible motive force to promote enterprise development, its core is the essence and values. Inching valve spring is a compression spring force to balance the role of the force on the valve. Helical coiled spring compression spring can be adjusted A27H inching valve sellers by turning it inching valve spring adjusting nut above, the use of such a structure can be corrected according to the safety valve opening (tuning) pressure . Spring inching valve structure is compact and lightweight A27H inching valve spring manufacturers, sensitivity is relatively high, the installation location is not restricted, but also because of the sensitivity of the vibration is small, it can be used on mobile pressure vessel.
