Body both sides are respectively equipped with the oil inlet and oil outlet communicated with valve, and the oil inlet leads to plunger shaft lower part, and the oil outlet leads to
Valve chamber, the solenoid valve be mounted on hydraulic control one-way valve upper end cover on, the solenoid valve be equipped with the first oil circuit, the second oil circuit and
3rd oil circuit, the first oil circuit lead 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 with the plunger shaft top split-phase above piston is controlled to connect.
Sealing ring is respectively equipped in 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 equipped at valve chamber between bottom end cover and valve body.
The oil outlet is close to valve chamber 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 solenoid valve on end cap, the piston bottom end of the logical hydraulic control one-way valve of solenoid valve oil circuit point, into and out of hydraulic fluid port both sides, with solenoid valve come
The open and close of arbitrary control hydraulic control one-way valve；Since 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.

Specific embodiment：
For that can understand the characteristics of illustrating this programme, the present invention is made into one below by specific embodiment and with reference to attached drawing
Walk explanation.
As shown in Figs 1-4：A kind of electromagnetism hydraulic control one-way valve, including solenoid 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 equipped in valve body
Plunger shaft 5 and valve chamber 6, the plunger shaft 5 is interior to be equipped with control piston 7, plunger shaft 5 is divide into upper part and lower part, in the valve chamber 6
Equipped with valve seat 8, nonreturn valve core 9 is installed on valve seat 8, spring 10, top and the spool phase of spring 10 are equipped with below nonreturn valve core 9
Even, the bottom of spring 10 is connected with bottom end cover 4, and the oil inlet 11 communicated with valve and oil outlet 12 are respectively equipped in valve body both sides,
The oil inlet 11 leads to 5 lower part of plunger shaft, the 12 port valve chamber 6 of oil outlet, and the solenoid valve 1 is mounted on hydraulic control one-way valve 2
Upper end cover 3 on, the solenoid valve 1 is equipped 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 lead to oil inlet 11 by oil pipeline, and the 3rd oil circuit 15 passes through upper end cover 3 and control
The 5 top split-phase connection of plunger shaft of 7 top of piston processed.
