One-way lock

One-way lockFDD200/40main application

In the hydraulic system, engineering often will control the oil of one actuator. The actuator stops at any position, be reliable locking action, so as to avoid displacement may occur under the effects of various factors.

One-way lockFDD200/40product instruction

Device FDD200/40 one-way lock branch road system or the working chamber of the liquid inlet and outlet, and pressure of the liquid on the system or the working chamber of the realization of a one-way closed,opened under pressure; parts after cleaning assembly, internal impurities of products than 10mg products after assembly, moving aflexible operation, no blocking phenomenon, the machine does notdue to mechanical damage;

Product storage and transportation should be rustproof dustproof measures;

Product manufacturing and acceptance by the implementation of the mt419-1995 standard.

One-way lock comprises a valve body, opened in the valve chamber of the valve body, spool, spool, valve seat is provided in the valvecavity of the return spring, and the valve body and valve seatarranged on one side of the liquid inlet valve cavity and the valve coreand valve cavity on one side of the liquid outlet; the valve cavity.Cavity through the valve body, sealing the valve cavity left port screwis connected with the end cover, the valve return spring is arranged on the end cover hole cavity; the valve seat is embedded in the valve seat sleeve; the valve seat valve cavity is provided with a side sealing and sliding push rod, the push rod extends to the seat sleeve, in the top rod is sheathed on the push rod return spring; port valve cavityright through the screw plug seal; in the thread plug valve cavity andpush rods and open control liquid inlet and outlet on the valve controlis.

One-way lock scope

①The hydraulic system of practical road and branch road valve head to31.5MPA, emulsified liquid medium containing 5% emulsion and 95% neutral water mixed, can work normally at 10 ℃ --50 ℃, media need tokeep clean, free of impurities. The filter and magnetic filtration devices to filter the precision of 0.125MM

②The valve in the underground as the need for maintenance,replacement should be whole, not to be overhauled in the underground, in order to prevent dirt into the valve cavity.
