Topic, applicant improves by repeatedly practice, devises a kind of SMD micro hydraulic locking-valve block.
Technical scheme：It is main the invention provides a kind of SMD micro hydraulic locking-valve block in order to realize foregoing invention purpose
To include spring, guiding valve, overflow valve, emergent interface, check valve and cutting ferrule interface.
There are spring and guiding valve inside the check valve, the lower section of the check valve is two symmetrical ferrule fittings, described
The lower section of ferrule fitting is overflow valve, and the top of the locking-valve block body is the jumper of two protrusions, the locking-valve block sheet
Four drift angles of body have a fixed structure respectively, and the fixed structure is snap bolt.
The number of the spring is at least a pair, and the number of the guiding valve is at least 2, and the spring top layer scribbles antirust
Erosion resisting coating, the thickness of the coating is 0.1-0.3mm, and the ferrule fitting is hex nut, and the overflow valve is hollow circle
Lubricating layer is scribbled between column structure, overflow valve and the locking-valve block body.
The check valve is plug-in one-way valve, and the number of the check valve is two groups, inside the locking-valve block body also
There is 3-position 4-way center-leakage type magnetic valve.
The locking-valve block body internal one-way valve is in inflow pipeline, when not having hydraulic oil in inflow pipeline, spring
Pretightning force shifts guiding valve onto centre position, and now pretightning force of spring or so is equal, and now, two groups of check valves are formed one group
Hydraulic lock, equivalent to hydraulic control one-way valve, it is ensured that hydraulic actuator inner rack displacement does not change.
When magnetic valve is not powered, hydraulic oil is enclosed in P mouthfuls, leads to when the magnetic valve left side obtains electric P mouthfuls and A mouthfuls, T mouthfuls and B
Mouth is logical, and the hydraulic oil of A paths pushes the check valve on the right open, while A paths hydraulic oil promotes guiding valve to be moved to the left, the push rod of guiding valve
The check valve on the left side is opened on top, and oil return line is opened, and in-line and oil return line are fully open, hydraulic actuator action；When magnetic valve is right
Lead to while obtaining electric P mouthfuls and B mouthfuls, T mouthfuls and A mouthfuls lead to, and the hydraulic oil of B paths pushes the check valve on the left side open, while B paths hydraulic oil is promoted
Guiding valve is moved right, and the check valve on the right is opened on the push rod top of guiding valve, and oil return line is opened, and in-line and oil return line are fully open, liquid
Press actuator action, A, B mouthful when input without hydraulic oil, spring reset promotes guiding valve, guiding valve is still in middle position, check valve reset by
Oil circuit is locked.
When power source hinders the pressure that can not provide hydraulic actuator unlatching for some reason, it is connected with emergent handlance with C, D mouthfuls,
Carry out emergency operation.
The overflow valve plays safe valve action in the entire system, when system pressure voltage supply increases or due to temperature liter
Hydraulic oil expansion in height, closing space, oil pressure rise, more than hydraulic actuator maximum allowable working pressure, overflow valve is opened,
Ensure the stable normal work of hydraulic actuator.
Beneficial effect：Compared with prior art, its advantage is the present invention：
1st, it is arranged on present invention, avoiding hydraulic control one-way valve in magnetic valve, hydraulic actuator and the connection production of solenoid valve box pipeline
Raw leakage causes fluid-control one-way defective valve, as long as being connected when emergent with portable hand-pressurized pump interface and emergent C, D, directly meets an urgent need,
It is simple and quick.
2nd, security performance of the present invention is high, extends the service life of hydraulic valve, effectively improves the detent pressure of hydraulic system.
3rd, the present invention is reasonable in design, is widely used in valve industry.
