Description
Technical field
The utility model is related to a kind of hydraulic valve, more particularly, to a kind of ultra-high pressure solenoid valve.
Background technology
With the development of science and technology, the pressure more and more higher of hydraulic pressure and pneumatic system, while automaticity is also more next
Higher, the high-pressure pneumatic system using pressure-air as working media is because its exclusive power density is high, instantaneous expansion is big, quick-fried
The characteristic such as strong, Acclimation temperature scope of having an effect is wide and obtained in the fields such as space flight and aviation, naval vessel, high-pressure air source car, engineering machinery
Using.Chinese patent discloses a kind of ultra-high pressure solenoid valve group（Authorization Notice No.：CN204677525U）, including electromagnetism changes
To valve, oil-return safety valve, oil-feed safety valve and oil-way integrated block, solenoid directional control valve uses three position four-way directional control valve, oil-feed safety
Valve and oil-return safety valve are provided with overload protection, the overflow when load exceedes the defined limit, system pressure is not further added by；Hydraulic control
One-way lock realizes that system holds lotus pressure holding function；System pressure data is uploaded to host computer by pressure sensor in real time, and the electromagnetism is changed
It is made up of to valve group work following core：Cylinder ejector：The left position of solenoid directional control valve, which is powered, to be connected, and fluid comes out from pump head,
Enter solenoid directional control valve by oil inlet and oil-way integrated block, come out from solenoid directional control valve, flow through fluid-control one-way lock and oil-feed peace
Full valve comes out from oil inlet is connected to oil cylinder oil inlet end；Oil cylinder oil revolving end fluid from oil return opening enter, by solenoid directional control valve from
Oil return opening outflows back to fuel tank；Oil cylinder moves back top：The right position of solenoid directional control valve, which is powered, to be connected, and fluid comes out from pump head, by oil inlet
Enter solenoid directional control valve with oil-way integrated block, come out from solenoid directional control valve, flow through oil-return safety valve and come out from oil return opening and be connected to
Oil cylinder oil revolving end；Crude oil cylinder oil inlet end fluid enters from oil inlet, and fuel tank is outflowed back to from oil return opening by solenoid directional control valve；Oil
Cylinder pressurize：System pressure is grasped by pressure sensor in real time in cylinder ejector, when pressure reaches setup pressure value, electromagnetism
Reversal valve power-off is in middle position, at this moment reaches system pressurize effect by hydraulic one-way lock, can be real-time when pressure has loss
Open solenoid directional control valve and carry out ftercompction；System unloaded：Due to using H type Median Function reversal valves, in solenoid directional control valve is in
During position, system automatic deloading.But the valve body of this solenoid directional control valve is easily deformed, card valve and Jie are easily produced when valve element works
The leakage of matter, and valve body easily produces physical change in installation process, and service life is shorter.
Utility model content
The utility model is to provide a kind of ultra-high pressure solenoid valve, and it is mainly the electromagnetism solved present in prior art
The valve body of reversal valve is easily deformed, and the leakage of card valve and medium is easily produced when valve element works, and valve body is in installation process
Easily produce physical change, the technical problem of the shorter grade of service life.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
Ultra-high pressure solenoid valve of the present utility model, including valve body, the two ends of described valve body are connected with electromagnet, valve
It is provided with vivo in superhard valve pocket, superhard valve pocket and is provided with valve element, connects the cavity of valve core outer surface, valve in superhard valve pocket provided with oil duct
The two ends of core are designed with stage clip.It can prevent high pressure conditions lower valve body from deforming using superhard valve pocket.Valve element is on its surface using not
Same technique, it is ensured that it reaches optimum state in geometry, service life, cooperation on interval, can farthest reduce card valve
With the leakage of medium.Alloy material is used on valve body, ensures stability of the material under various operating modes after treatment.
Preferably, described valve body is provided with oil inlet, oil return opening connection valve inner oil pocket.Oil inlet, oil return opening
The same side is located at, so installs more convenient.
Preferably, the inner of described stage clip is provided with pad.
Preferably, the valve opening inner surface of described valve body, which is provided with wearing layer, wearing layer, is provided with dashpot.To valve body
Mounting hole carries out specially treated, it is ensured that valve body does not produce physical change in use.Wearing layer can increase wearability, delay
Jet-bedding can ensure that fluid flowing will not be very rapid, run more steady.
Therefore, valve body of the present utility model will not be deformed, and valve element will not produce the leakage of card valve and medium when working, and
Valve body will not produce physical change in installation process, and service life is longer, simple and reasonable for structure.
