Dalian T40H type manual regulation characteristics of pneumatic valve

dalian type manual regulation of pneumatic valve and self-locking manually adjust the pneumatic valve is mainly used in urban central heating, district heating, circulating water engineering, thermal power plant pipe network and refrigeration and air conditioning engineering, have the function of the globe, throttling and regulating flow, to replace the throttling orifice plate, is a kind of changing the aperture throttling device.

TH dalian type manual regulation characteristics of pneumatic valve:
, improve the working condition of heating: all manually adjust the line and thermodynamic point of pneumatic valve, flow control can be designed according to their working conditions, good temperature conditions, the pneumatic regulating pneumatic valve than gate valves, globe pneumatic valve regulating performance is good, it is approximate linear regulation performance, therefore, the heating buildings improve the phenomenon of uneven and powerful.
, to save energy: heat pipe due to disorders of temperature and pressure, causing some traffic, make some construction temperature is too high, the user will have to open the window, a large amount of heat energy waste, because the branch pneumatic valve installed manual adjustment, overcome the disorder of temperature and pressure, avoid open the window, achieve the goal of energy saving.
, improve the working condition of hydraulic, manual regulation pneumatic valve can be carried out in accordance with the rated flow control, cut the flow of pipe network excess run, make originally deteriorating water level has been improved to a certain.
