進口氮氣減壓閥產品簡介:

德國洛克《DE LOCKE》進口氮氣減壓閥（Nitrgen pressure reducing valve），也叫氮氣調壓閥，是指用于氮氣介質，通過調節彈簧壓力設定出口壓力、利用膜片傳感出口壓力變化，通過導閥啟閉驅動活塞調節主閥節流部位過流面積的大小，實現對壓縮空氣的減壓穩壓功能。從流體力學的觀點看，減壓閥是一個局部阻力可以變化的節流元件，即通過改變節流面積，使流速及流體的動能改變，造成不同的壓力損失，從而達到減壓的目的。然后依靠控制與調節系統的調節，使閥后壓力的波動與彈簧力相平衡，使閥后壓力在一定的誤差范圍內保持恒定。

Germany lok "DE LOCKE" import Nitrgen pressure reducing valve (Nitrgen pressure reducing valve), also known as the Nitrgen pressure regulating valve and means used in the Nitrgen medium, by adjusting the spring pressure setting outlet pressure, the use of diaphragm sensing outlet pressure changes, through the pilot valve opening and closing drive piston to adjust the size of the main valve throttle position over-current, achieve the function of decompression of the compressed air regulator. From the point of view of fluid mechanics, pressure reducing valve is a local resistance can change the throttle element, that is, by changing the throttling area, so that the flow rate and fluid kinetic energy change, causing different pressure loss, so as to achieve the purpose of decompression. Then rely on the control and regulation of the system, so that the valve after the pressure fluctuations and spring force balance, so that the valve after the pressure in a certain error range to maintain a constant.
