What is the characteristics of pneumatic trap?

Pneumatic trap is hydrophobic according to thermal power plant equipment and professional design and production of a new generation of steam trap, the product is close to the linear flow design, reduce the flow resistance, secondary throttle principle, reduce erosion, improve the life. Valve core and valve seat adopt solid carbide, shut off the leak < = VI level, removable midplane seal design, put an end to leakage, maintenance is convenient wait for a characteristic, but also in flammable, explosive occasions to use, according to the control system, or adjust the signal of instrument, cut off or open the valve, so as to realize the use of accused parameters requirements. So it is widely applied in coal-fired power plants and other industries of the remote control. Features: pneumatic trap by the positive action and reaction, their level of nominal diameter DN ( MM） From 20 ~ 100; Nominal pressure level PN by 150 lb ( 2. 0MPa） Such as multiple hierarchical; Air pressure ( MPa） 0. 14 - 0. 4. The signal range (Pr KPa） 20 - 100; 40 - 200; Leakage almost approximate to zero leakage of the product has a variety of specifications to choose from. Y type steam trap is pneumatic control valve with special structure of two side is welding type, suitable for specific piping. Pneumatic actuator of trap, the two kinds of forms; When the signal pressure increases, putting out membrane chamber is called role, and the valve with a gas type. When the signal pressure increases, putting back into the film chamber called a backlash, with the valve open. Basic function is to trap the steam system of the condensate, air and carbon dioxide gas discharge as soon as possible; At the same time maximize the automatically to prevent leakage of steam. Steam traps many varieties, each have different performance. Selection of steam trap, the first elected its features can best meet the steam heating equipment operation, before considering other objective conditions, so choose what you need steam traps is correct and effective.
