產品型號及標志方法

??當壓力潤滑系統(tǒng)中的潤滑油進入閥內，通過閥芯的阻尼小孔推動膜片組合件(達到開啟壓力6kgf/cm2)而通過并扒動鋼球和壓縮彈簧而流過。若R向液壓高于P向液壓，則膜片組合件和鋼球組合件關閉，達到防止壓力潤滑油反向流動的目的。
??注：上述參數(shù)位2片膜片，若膜片為1片時，彈簧改為4.5X11X0.5時，開啟壓力為6kgf/cm2。

General
??Film check valve is used in pressure lubricating system to prevent refluence of lubricating oil and keep certain pressure, it can be widely used in lubricating systems of machine, petroleum, chemical, fertilizer, power and light textile.
Product model and identification
??When lube of pressure lubricating system enter into valve, film assembled(reach cracking pressure 6kgf/cm2) are pushed through steel ball 3 hold and spring 2 compressed. If hydraulic pressure of R direction is higher than that of P direction, film assembled and steel ball assembled will close so that prevent pressure lube from reveres flowing.
??Note: parameter above is 2 films. If it is one film and spring is changed to 4.5×11×0.5, cracking pressure is 6kgf/cm2．
