Description
Technical field
The invention belongs to technical field of hydraulic pressure, are related to a kind of automatically controlled one-way valve, the stable automatically controlled list of especially a kind of performance
Road valve.
Background technique
One-way valve is to change the on-off pass for the oil duct being connected on valve body by the relative motion between spool and valve body
The valve class of system, has a wide range of applications in mechanical equipment, and each workpiece of existing one-way valve is seperated design, valve body structure
It is not compact, and operation is not sufficiently stable.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, a kind of stable automatically controlled single channel of performance is proposed
The technical issues of valve, solution is how to improve structural compactness.
Object of the invention can be realized by the following technical scheme: a kind of stable automatically controlled one-way valve of performance, including valve
Body and the solenoid valve being installed on valve body, which is characterized in that oil inlet is offered on the valve body, the oil inlet connects
It is connected to system safety valve, the system safety valve, which is connected with, connects valve port, and the valve inner is provided with check valve, described
Valve inner be provided with valve shaft, and the valve shaft and check valve are in a straight line, are opened between the oil inlet and solenoid valve
Oil circuit equipped with connection offers the oil circuit being connected with solenoid valve, the solenoid valve between the check valve and valve shaft
The oil circuit being connected to is offered far from the side of check valve with valve shaft, the valve body offers rod chamber interface at check valve,
The valve body offers rodless cavity interface at valve shaft, the solenoid valve with connect the oil circuit for offering and being connected between valve port,
Several sealing rings made of rubber material are arranged in the circumferential wall of the valve shaft.
The working principle of the automatically controlled one-way valve: when Positive work, hydraulic oil flows into valve body from oil inlet, then passes through electromagnetism
Valve flows between valve shaft and check valve, flows into rod chamber by check valve and from rod chamber interface, the hydraulic oil in rodless cavity from
Valve body is flowed into rodless cavity interface, flow into solenoid valve far from the side of check valve from valve shaft and flows out valve body from valve port is connect.Reversely
When operating, hydraulic oil flows into valve body from oil inlet, then passes through solenoid valve and flow through side of the valve shaft far from check valve, from no bar
Chamber interface flows into rodless cavity, and the hydraulic oil in rod chamber flows into valve body from rod chamber interface, due to flowing into the hydraulic of rodless cavity
Valve shaft is pushed to check valve side and is opened check valve when by valve shaft by oil, therefore the hydraulic oil in rod chamber can be from list
Solenoid valve is flowed out and flowed into stream, and valve body is flowed out from valve port from connecing.When the oil pressure in one-way valve is excessively high, hydraulic oil can be pushed away
Open system safety valve simultaneously flows directly out valve body from connecing from valve port.
In the stable automatically controlled one-way valve of above-mentioned performance, the solenoid valve is 3 position-5 way solenoid directional control valve.
Compared with prior art, the stable automatically controlled one-way valve of this performance is by the way that check valve and valve shaft to be set in valve body
Portion, and work requirements only can be met by a check valve, it is compact-sized and stable.
