Faults and eliminate (1) does not return after the discharge valve seat. This is mainly a spring bent stem, valve installation caused by malposition or stuck. It should be re-assembled. (2) less than the required pressure is on. The main constant pressure allowed; spring stretch down the aging. It should be properly tightened adjustment screw or replace the spring. (3) valve frequency hopping or vibration. Mainly due to the stiffness of the spring is too large. You should use the appropriate spring stiffness; adjustment ring to adjust properly, so that the back seat pressure is too high. Should readjust the position of the adjustment ring; discharge piping resistance is too large, resulting in excessive emissions of back pressure. Discharge pipe resistance should be reduced. Safety valve stainless steel valves species means opening height of not less than 1/4 the diameter of the valve flow channel. This safety valve operating characteristics belonging to two-acting valve. The main parameters of the safety valve displacement stainless steel valves brand, the displacement depends on the caliber of the valve seat and valve opening height, the opening height of different models of stainless steel valves, is divided into Weiqi the entire Kai two. Weiqi is the valve opening height for the seat throat diameter of 1/40 ~ l / 20. Entire Kai is the valve opening height for the seat throat diameter of 1/4. Safety valve to be fitted with a discharge pipe. Discharge pipe to avoid twists and sharp turns to minimize drag. To discharge tube through a safe place, and there is enough flow area to ensure the exhaust flow. For the safety valve can interact to produce a chemical reaction, can not share a discharge pipe; when the valve is mounted on the corrosive, flammable gas equipment, should also take anti-corrosion or anti-fire explosion measures emissions; when installed security valve equipment for toxic media, and the vapor density of the medium is greater than the density of air, from the media and steam safety valves discharged to be introduced into a closed system, and recovering from a closed system into production use.
