Description
Technical field
This utility model belongs to technical field of hydraulic pressure, is related to a kind of one-way valve, particularly to a kind of automatically controlled one-way valve.
Background technology
The relative motion that one-way valve is made by between valve element and valve body is closed come the break-make to change the oil duct being connected on valve body
The valve class of system, has a wide range of applications, each workpiece of existing one-way valve designs for split, valve body structure in plant equipment
Not compact, and run be not sufficiently stable.
Content of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, there is provided a kind of compact conformation, fortune
The stable automatically controlled one-way valve of row.
The purpose of this utility model can be realized by following technical proposal: a kind of automatically controlled one-way valve, including valve body and
The electromagnetic valve that is installed on valve body is it is characterised in that offer oil-in on described valve body, described oil-in is connected with and is
System relief valve, described system relief valve is connected with and connects valve port, and described valve inner is provided with check valve, described valve body
It is internally provided with valve shaft, and described valve shaft is in a straight line with check valve, the company of offering between described oil-in and electromagnetic valve
Logical oil circuit, offers the oil circuit being connected with electromagnetic valve, described electromagnetic valve and valve shaft between described check valve and valve shaft
Side away from check valve offers the oil circuit of connection, and described valve body offers rod chamber interface at check valve, described
Valve body offers rodless cavity interface at valve shaft, and described electromagnetic valve offers, with connecing, the oil circuit connecting between valve port.
The operation principle of this automatically controlled one-way valve: during Positive work, hydraulic oil flows into valve body at oil-in, then pass 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
Flow into valve body in rodless cavity interface, flow out valve body from valve shaft away from a side inflow electromagnetic valve of check valve and from connecing valve port.Reversely
During operating, hydraulic oil flows into valve body at oil-in, then by electromagnetic valve and flows through the side away from check valve for the valve shaft, from no bar
Chamber interface flows in rodless cavity, and the hydraulic oil in rod chamber flows into valve body from rod chamber interface, due to flowing into the hydraulic pressure of rodless cavity
Valve shaft is promoted and opens to check valve side check valve when through valve shaft by oil, and the therefore hydraulic oil in rod chamber can be from list
Flow out at stream and flow into electromagnetic valve, and flow out valve body at connecing valve port.When the oil pressure in one-way valve is too high, hydraulic oil can push away
Open system relief valve simultaneously flows directly out valve body at connecing valve port.Check valve and valve shaft are arranged in valve body this automatically controlled one-way valve
Portion, and only work requirements can be met by a check valve, compact conformation and stable.
In above-mentioned automatically controlled one-way valve, described electromagnetic valve is 3 position-5 way solenoid directional control valve.
In above-mentioned automatically controlled one-way valve, the circumferential wall of described valve shaft is arranged with several sealing rings.
Compared with prior art, check valve and valve shaft are arranged at valve inner by this automatically controlled one-way valve, have compact conformation,
Stable advantage.
