The working principle of this specific implementation are as follows: when electromagnetic valve coil is powered, coil generating electromagnetic power, dynamic iron core is by magnetic by bullet
Spring compression is attracted with fixed core, while being lifted off a seat with ovable valve stem and small piston.When medium enters cavity from the right end of valve body,
Have a upward thrust F1 to valve rod and small piston, medium enters valve body epicoele by seal receptacle 31, to valve rod have one to
Under pressure F2, F1 with F2 forced area it is identical, it is contrary, can cancel out each other.Similarly, when medium enters valve body from left end
When, medium has a upward power F1 to valve seat, while medium enters the epicoele of valve body by technique ditch through-hole, has one to valve rod
A downward power F2, since pressure medium is identical, valve rod is identical with valve seat forced area, and contrary, F1 and F2 are mutually supported
Disappear.When unicoil powers off, the electromagnetic force of coil disappears, and dynamic iron core moves downward under the action of self weight and spring force, closes valve
Door.Fire valve peculiar to vessel is balanced using pressure balance type design feature using the special structure form of valve body and valve inner body
Medium acts on the power on valve seat, passes through the electromagnetic attraction and reset spring of coil, so that it may realize the opening and closing of valve.
It is worth noting that, being originally embodied in the sealing structure of valve, using flat seal, in small piston bottom
Design has the round cushion block of 5mm high, owes standard to valve seat centering to make up small piston, in addition piston pressing plate function on cushion block,
Certain protective effect is lined with to rubber seal.The sealing stress surface born on valve seat is on the annulus of 0.5mm, so sealing is tight
Close be not easy interior leakage, the material selection of gasket wearability is good, rubber with high hardness.
This specific implementation is in use, using in valve body and the special structure form balancing work medium pressure of the inner body of valve
Power can realize the opening and closing of valve by the electromagnetic force and reset spring of coil.When electromagnetic valve coil is powered, generation is electric
Magnetic force makes dynamic iron core that small piston be driven to move upwards, and small piston is lifted off a seat, and medium flows to going out for valve by valve seat from import
Mouthful, while dynamic iron core drives upper valve rod, passes through the close switch of permanent magnet induction, feedback switch valve signal.On the contrary, electromagnetic valve coil is disconnected
After electricity, under the action of the spring, dynamic iron core drives small piston to return to original position, seals valve seat, and medium interrupts.The case where having a power failure
Under, it can be used the hand gear of lower part, when valve opening, regulating valve cap nut, drives adjusting spool to transport upwards rotationally clockwise
It is dynamic, it jacks up small piston and lifts off a seat, medium flows to outlet through valve seat from import.On the contrary, rotating in an anti-clockwise direction adjusting when closing
Valve nut drives adjusting spool to move downward, and small piston returns to original position, and medium interrupts.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
