How to use the safety valve of air compressor

      Selection of safety valve of air compressor

     Nominal pressure is decided by the operating pressure of safety valve by the operating temperature range, temperature determines the safety valve set pressure value, the spring or lever set pressure range determined the calculated safety valve, according to the decision to use media materials and structure type safety valve,safety valve discharge to calculate the safety valve throat sizeaccording to the. The following general rules for the safety valve of choice.

     (1).Hot water boiler is not closed with the general use of micro open type safety valve wrench.

     (2).Steam boiler or steam pipe is not closed with the general use of full Kai type safety valve wrench.

     (3).Water and other liquids can not be closed for general usecompressed medium inching valve, or safety relief valve.

      (4).High-pressure water for general use of closed valve, such as high-pressure feedwater heater, heat exchanger etc..

       (5).Gas can be generally closed to the safety valve of compressedmedium, such as the gas tank, gas pipelines.

       (6).Esteam boiler safety valve for general use static weight.

       (7).Large diameter, large discharge capacity and high pressure systems generally use pulse valve, such as temperature and pressure equipment, boiler, as shown in figure 8.

      (8).The train transporting liquefied gas tanker, tank trucks, tanks and other general use built-in safety valve, shown in figure 4.

Gear Rack

        (9).Safety valve hydraulic tank top general, be used in conjunction with the breathing valve.

       (10).Natural gas pipeline underground drainage or the general use of the pilot type safety valve, as shown in figure 6.

        (11).Liquefied petroleum gas station can pump the liquid return pipe on the general safety valve.

        (12).The system may produce negative pressure or negative pressure during operation of the vacuum valve for general use.

         (13).The back pressure and toxic volatile flammable container or piping system is generally used Bellows Safety valve.
