Description
Technical field
The present invention relates to Solenoid Valve Technology field, especially a kind of isolated lever magnetic valve.
Background technique
Solenoid valve is electromagnetically controlled industrial equipment, is the automatic foundamental element for controlling fluid, conventional electricity
Magnet valve pulls movable core mobile or resets generally by electromagnetic force, and movable core is equipped with sealing element, directly controls main valve
The switch of mouth or pilot valve mouth；It is understood that the solenoid valve of different bores is at various pressures, the higher needs of the bigger pressure of bore
The power for keeping movable core mobile is bigger, this power is to be generated by the electromagnetic force of electromagnetic coil, therefore need in this case
The power or volume of electromagnetic coil are bigger, this is just unfavorable for the exquisitenessization design of solenoid valve.
Requirement of the common solenoid valve to fluid be it is very high, it requires the viscosity of fluid cannot be too high, and cleanliness is necessary
It is better, cannot have impurity, fluid acid-base property must be close to neutrality etc., otherwise may cause components in valve and block and do not work, most
Final acceptance inspection card influences the performance of solenoid valve.Therefore isolated structure can be avoided problems.There is isolation in existing market
Solenoid valve mainly have 2 kinds, one is direct diaphragm is isolated, the solenoid valve of this structure often flow latus rectum very little, pressure
It is very low；Another kind is that an O-ring is set on spool, makes iron core and fluid isolation by O-ring, this structure is more complicated, again
Because spool and O-ring make dynamic sealing, the effect of sealing is not highly desirable.
A kind of combustion gas isolated form embedded-type electric magnet valve as disclosed in Chinese invention patent CN103322276A.A kind of combustion gas
Isolated form embedded-type electric magnet valve, including valve body, the valve body left upper portion are equipped with buting iron, are equipped with lever, institute below the buting iron
It states lever to connect by spring with valve body, be in close contact below lever by the sealing valve mouth of gasket and valve body, the valve body
Sealing valve port is connected to the intracorporal inlet channel of valve, and the lever is contacted with guide pipe, and electromagnetic wire is equipped with around the guide pipe
Circle, the electromagnetic coil outside are equipped with embedded solenoid valve casing, and when electromagnetic coil is powered, buting iron attracts lever to make gasket
Far from valve seal valve port；The isolated form embedded-type electric magnet valve of the patent of invention can not achieve the complete of fluid and electromagnetic actuator device
Full isolation.
Summary of the invention
The present invention be directed to the drawbacks described above present in the prior art, spy proposes a kind of isolated lever magnetic valve, solves
Existing solenoid valve can not achieve the completely isolated problem of fluid and electromagnetic actuator device, and get in face of solenoid valve bore
