Description
Technical field
The utility model relates to a kind of electric check valve more particularly to a kind of electric check valves with long service life.
Background technique
Shut-off valve, also known as pipe valve are a kind of valves for being usually used in playing the medium in pipeline cutting and throttling.Shut-off valve by
The components such as valve seat, valve rod composition, further includes the opening and closing element for having a stopper --- flap, and flap is made straight along the center line of valve seat
Line movement.Shut-off valve relies on the pressure of valve thick stick, i.e. valve rod makes valve clack sealing surface by applying pressure to flap in the axial direction
It is fitted closely with sealing surface of seat, realizes cutting, the throttling to medium.Electric check valve is to rely on to be driven by electricity valve rod shifting
A kind of dynamic shut-off valve.
However in general figure is bigger for the Electric Actuator on electric check valve, weight is also larger.Section on the market
Only the moiety by weight of the Electric Actuator of valve, which is applied to, protrudes on valve rod therein, by the flank load-bearing on valve rod.It is aobvious and
It is clear to, such load bearing manner not only built on the sand and is very easy to cause thread abrasion on valve rod.The screw thread one side nothing of abrasion
Auxiliary electric actuator goes up and down valve rod to method again, and the weight that on the other hand can not also undertake Electric Actuator again is just held over time
The damage of shut-off valve is easily caused.
