Hydraulic pneumatic control valve selection and matters needing attention

hydraulic pneumatic control valve is controlled hydraulic pneumatic valve, pneumatic valve and it consists of a main attached catheter, guide pneumatic valve, needle type pneumatic valve, pneumatic ball valve and pressure gauge, etc. http://www。 zgbfw。 Com/info /
to use hydraulic pneumatic control valve, the first thing to pay attention to the selection. Improper selection, will cause the resistance and water leakage phenomenon. When choosing hydraulic pneumatic control valve, according to the equipment per hour of steam consumption multiplied by the ratio - Times for maximum condensation water, to select the displacement of hydraulic pneumatic control valve. To ensure hydraulic pneumatic control valve to discharge the condensate as soon as possible, while driving rapidly increase the temperature of the heating equipment. Hydraulic pneumatic control valve to discharge energy is insufficient, will cause the condensate can not discharge in time, reduce the thermal efficiency of heating equipment. http://www。 zgbfw。 Com/info /
when choosing hydraulic pneumatic control valve, pneumatic valve can't choose to nominal pressure hydraulic control, because the nominal pressure can only be said hydraulic pneumatic control valve body shell under pressure rating, hydraulic pneumatic valve control nominal pressure and pressure difference is very big. So according to the working pressure difference to select displacement of hydraulic pneumatic control valve. Working pressure difference refers to the working pressure hydraulic pneumatic control valve before minus hydraulic pneumatic control valve outlet back pressure difference. Choose hydraulic pneumatic control valve requirements accurately and correctly the gas drainage resistance, high sensitivity, can improve the utilization rate of steam, steam leakage, has reliable performance, high back pressure ratio, long service life, convenient maintenance is preferred.
