09 2020-09 The difference between the solenoid valve explosion-proof (EXd) and intrinsically safe explosion-proof (EXi) of the pneumatic cut-off valve The difference between the explosion-proof solenoid valve (EXd) and intrinsically safe explosion-proof (EXi) equipped with pneumatic ball valve, pneumatic cut-off valve and pneumatic emergency cut-off valve is that more than 80% of the production workshop areas have combustible substances, so it is necessary to adopt electronic components for explosion-proof -
06 2020-09 Pump process flow and control method of shut-off valve Pump process flow and shut-off valve control method: the standard is applicable to the selection of pump process flow and shut-off valve (pneumatic emergency shut-off valve, electric emergency shut-off valve) control method of oil refining unit. The article is from East China Petroleum Exploration and Design Institute -
thirty 2020-08 Air consumption calculation method for pneumatic cut-off valve pneumatic ball valve application Shanghai cut-off valve manufacturer: introduce the way to calculate the air consumption of actuators of pneumatic cut-off valve, pneumatic ball valve, pneumatic emergency cut-off valve and liquid ammonia emergency cut-off valve, so as to provide a reference for users in selecting the capacity of air compressor and the volume of air storage tank -
thirty 2020-05 Block valve model compilation - complete picture of block valve The cut-off valve is generally called emergency cut-off valve. The actuator of pneumatic cut-off valve and hydraulic cut-off valve shall be equipped with an automatic cut-off device for fusible elements. When the ambient temperature exceeds the melting point set for the emergency cut-off valve, the valve can automatically and quickly close and cut off the flow of media. ...... -
twenty-seven 2020-05 Meaning of shut-off valve - pressure test method of shut-off valve Cut off means to close, cut off, cut off, stop, and stop. The valve is the form of structure. The meaning of cut off valve includes all automatic control valves: electric valve, pneumatic valve, hydraulic valve, high-temperature fuse device, electro-hydraulic linkage valve, pneumatic hydraulic linkage valve -
