Gas heater valve lifting requirements


   Should be used at high intensity, long enough rope fixed to the lifting screw, ensure the rope angle of less than 60 °, lifting; Gas Heater Valve in the lifting, tying the sling is not allowed in the gas heater valve end cap on the gas heater valve neck, or gearing To move smoothly to avoid shocks.
 Distance from the center of the pump outlet gas heater valve should be greater than 2000mm, if you can not meet this condition, to take rectification measures, where possible, the conditions should try to increase this distance in order to reduce the adverse effects of the turbulent flow regime pump outlet of the gas heater valve.
 Some still some speakers pump outlet pipe, gas heater valve fully open, the disc should be within flare.
 The butterfly patio heater valve body is mainly composed, transmission, hydraulic and electrical control components. Has the following main features:
 The gas heater valve main seal type is: Stainless steel - stainless steel, and with three eccentric structure, so reliable sealing performance, and the disc more closed more tightly, easy to disengage; ring made of stainless steel, corrosion resistance and long service life.
 For lead-bearing non-oil self-lubricating bearings, with strong bearing capacity, wear resistance, friction resistance and other characteristics; shaft seal with self-tightening and other double-sealed, good sealing effect; disc shape with streamlined design, has a small Gas Control Valves coefficient of flow resistance (≤0.2), novel appearance, appearance and other characteristics.
 In short, the accumulator tank hydraulic control slow closing check gas heater valve in the application of the pumping station, with easy operation, investment, quick, favorable energy efficiency and many other advantages, in a similar pump station application.
