Valve element, is provided with spring below nonreturn valve core, and the top of spring is connected with valve element, and the bottom of spring is connected with bottom end cover, in valve
Body both sides are respectively equipped with the oil inlet and oil-out communicated with valve, and the oil inlet leads to part under plunger shaft, and the oil-out leads to
Valve pocket, the magnetic valve be arranged on hydraulic control one-way valve upper end cover on, the magnetic valve provided with the first oil circuit, the second oil circuit and
3rd oil circuit, the first oil circuit leads to oil inlet by pipeline road pass-out hydraulic fluid port, the second oil circuit by oil pipeline, and the 3rd oil circuit leads to
Upper end cover is crossed to connect with the plunger shaft top split-phase above control piston.
Sealing ring is respectively equipped with the first oil circuit, the upper end cover of the second oil circuit and the 3rd oil circuit and valve body junction.
Sealing ring is provided with valve pocket between bottom end cover and valve body.
The oil-out is close to valve pocket top.
Beneficial effects of the present invention：Based on existing common hydraulic control one-way valve, in the control piston end of hydraulic control one-way valve
Increase magnetic valve on end cap, the piston bottom end of the logical hydraulic control one-way valve of magnetic valve oil circuit point, into and out of hydraulic fluid port both sides, with magnetic valve come
The open and close of any control hydraulic control one-way valve；Because electromagnetism hydraulic control one-way valve sealed nature belongs to the sealing of No leakage cone valve, Gu Qimi
Envelope is good, realizes the reliable pressurize of one-way cylinder.

Embodiment：
The characteristics of for explanation this programme can be understood, the present invention is made into one below by embodiment and with reference to accompanying drawing
Walk explanation.
As Figure 1-4：A kind of electromagnetism hydraulic control one-way valve, including magnetic valve 1 and hydraulic control one-way valve 2, the fluid-control one-way
Valve 2 includes valve body and is arranged on the upper end cover 3 of valve body upper end and is arranged on the bottom end cover 4 of valve body lower end, is provided with valve body
Provided with control piston 7 in plunger shaft 5 and valve pocket 6, the plunger shaft 5, by plunger shaft, 5 points are in two parts up and down, the valve pocket 6
Provided with valve seat 8, nonreturn valve core 9 is installed on valve seat 8, spring 10, top and the valve element phase of spring 10 are provided with below nonreturn valve core 9
Even, the bottom of spring 10 is connected with bottom end cover 4, and the oil inlet 11 and oil-out 12 communicated with valve is respectively equipped with valve body both sides,
The oil inlet 11 leads to 5 times parts of plunger shaft, and the port valve chamber 6 of oil-out 12, the magnetic valve 1 is arranged on hydraulic control one-way valve 2
Upper end cover 3 on, the magnetic valve 1 is provided with the first oil circuit 13, the second oil circuit 14 and the 3rd oil circuit 15, and the first oil circuit 13 passes through
Pipeline road pass-out hydraulic fluid port 12, the second oil circuit 14 leads to oil inlet 11 by oil pipeline, and the 3rd oil circuit 15 passes through upper end cover 3 and control
The top split-phase connection of plunger shaft 5 of the top of piston 7 processed.
Sealing is respectively equipped with the first oil circuit 13, the second oil circuit 14 and the upper end cover 3 of the 3rd oil circuit 15 and valve body junction
Circle 16.
