Simple introduce safety of pneumatic valve and pneumatic valve production process

security pneumatic valve is in a normally closed state, only within the device set pressure exceeds allowable values, pneumatic valve automatically opens, emissions to equipment set order numerical pneumatic valve automatically back to do, for a second protection. Although security pneumatic valve is to protect the equipment and the personal safety of pneumatic valve, pneumatic valve opening times will not too much but security. Because there was a problem in every open means equipment.
security pneumatic valve manufacturing very numerous
specific wu big steps completed safety pneumatic valve
the first choice material, according to adapt to temperature, medium, to choose the appropriate materials. Security pneumatic valve temperature commonly used material for: carbon steel, cast steel. When the corrosive medium usually choose: stainless steel ( Roughly divided into stainless steel, temperature is high, L need to choose: the chrome molybdenum steel, or chrome molybdenum steel. When the medium corrosive ultra-high optional four fluorine lining material.
2, pneumatic valve body, need according to the type selection, regulation stipulates the abrasive pneumatic valve body.
3, sealing surface, pneumatic valve sealing surface is very delicate, steps, from the master by the hand a little bit of my factory grinding and become, but pure manual grinding.
the fourth try, pressure, pneumatic valve, to have completed a process with the need to be very important, now it is on the pipeline pressure test, place the pneumatic valve for pressure testing of piping, according to customer's requirement by our professional testing technicians set pressure, after the success of the pressure setting. You need to pneumatic valve is the final step to make success.
5, spray paint, place the pneumatic valve, special paint spraying equipment for final processing. Pneumatic valve body was the main reason for this step is beautiful, need to wait after the paint dry container shipment.
