Introduction of self-operated differential pressure regulating valve
V C )型直接作用式微压、差压调节阀是一种无需外加能源,利用被控介质自身能量当动力源,引入执行机构膜室产生推力,控制节流元件运动达到自动调节。 The ZZ ( V , C ) type direct-acting micro-pressure and differential pressure regulating valve is a type that requires no additional energy, uses the energy of the controlled medium as the power source, and introduces the actuator membrane chamber to generate thrust, which controls the movement of the throttle element to achieve automatic adjustment. ZZDG 型供氮调节阀和 ZZDX 型泄氮调节阀。 Mainly used in various industrial furnace gas combustion systems to control the mixed flow rate of A and B fuels to achieve the ideal natural conditions: used in hydrogen-cooled generator set sealing oil and hydrogen, liquefied gas, oxygen, nitrogen and other industries Gas decompression, pressure stabilization, and pressure relief adjustment: used for various oil, chemical, and liquid storage tank gas seals. In some cases, it can replace our factory's ZZDG type nitrogen supply regulator and ZZDX type nitrogen relief regulator. 0.2MPa )可取代本厂的 ZZYP- 10-16 )Ⅱ型指挥器操作型自力压力调节阀。 When the pressure in front of the valve is low (for example, the pressure in front of the valve is less than 0.2MPa ), it can replace our factory's ZZYP- ( 10-16 ) type II pilot operated self-operating pressure regulating valve.
