Safety valve 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, the displacement depends on the caliber of the valve seat and valve opening height, by the opening of different height, then 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. Body material: cast iron, steel, stainless steel, forged steel, chrome molybdenum steel, chrome molybdenum vanadium steel. Working pressure 1.6-32MPA (American Standard from 150LB-2500LB, Japanese standard from 10K-64K). Operating temperature -20 ℃ -550 ° C valve diameter from DN15-DN300 Connection: flange, silk mouth or welding. Drive: manual, electric, pneumatic, bevel gears, spur gears. Suitable medium: water, oil, gas, steam and so on. Safety valve to be fitted with a discharge pipe. Discharge pipe to avoid twists and sharp turns Weifang stainless steel valves to minimize drag. To discharge tube through a safe place, and there is sufficient cross-sectional area of ??the flow of stainless steel valve type, 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 stainless steel valves species should be protected against corrosion or anti-fire explosion measures emissions; when equipment for the installation of a safety valve in the 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.
