Abstract
The invention discloses a bidirectional hydraulic lock comprising a valve body. The bidirectional hydraulic lock is characterized by comprising a left valve element, a right valve element, two push rods and a piston, wherein two valve cavities are formed in the valve body, the left valve element and the right valve element are arranged in the valve cavities respectively, the piston is arranged in the middle of the valve body, the piston is connected with the left valve element and the right valve element through the two push rods, each valve cavity is connected with an oil inlet and an oil outlet through a pipeline, the valve elements can block the pipelines between the oil inlets and the oil outlets, springs connected with the valve body are arranged in the left valve element and the right valve element respectively, and the pipelines can convey pressure oil to the piston. The bidirectional hydraulic lock solves the problems that, in the prior art, a hydraulic one-way valve is adopted, when the hydraulic one-way valve is not used, return oil still flows, a valve element in the hydraulic one-way valve will be damaged, and the service life of the hydraulic one-way valve is influenced. The bidirectional hydraulic lock is simple in structure, convenient to use and capable of avoiding flow of return oil and enabling a one-way valve to be in a self-locked state.
Description
Technical field
The present invention relates to a kind of hydraulically-controlled one-way valve, particularly relate to a kind of bidirectional hydraulic lock.
Background technique
Pilot operated check valve relies on to control hydrodynamic pressure, can make the valve of one-way valve reverse circulated.But current hydraulically-controlled one-way valve, when not using state, loop fluid still has flowing, damage can be caused to the spool in hydraulically-controlled one-way valve like this, affect its working life, and when opening state, can affect to use, destroy normal flowing velocity.
Summary of the invention
In order to solve hydraulically-controlled one-way valve in prior art, when not using state, loop fluid still has flowing, can cause damage like this to the spool in hydraulically-controlled one-way valve, affect its working life, and when opening state, can affect to use, destroy the problem of proper flow speed, the invention provides a kind of structure simple, easy to use, loop fluid can be realized without flowing, make one-way valve be in the bidirectional hydraulic lock of self-locking state.
In order to solve the problem, the technical solution used in the present invention is:
A kind of bidirectional hydraulic lock, comprise valve body, it is characterized in that: also comprise left spool, right spool, two push rods and a piston, two valve pockets are provided with in valve body, left spool or right spool is provided with in valve pocket, piston is provided with in the middle part of valve body, described piston is connected with left spool or right spool respectively by push rod, described each valve pocket is connected with an oil outlet with a filler opening respectively by pipeline, described spool can block the pipeline between filler opening and oil outlet, the spring be connected with valve body is provided with in described left spool or right spool, described pipeline can to piston discharge pressure oil.
Aforesaid a kind of bidirectional hydraulic lock, is characterized in that: in valve pocket, be horizontally disposed with left spool or right spool.
Aforesaid a kind of bidirectional hydraulic lock, is characterized in that: described left spool and right spool are symmetrical arranged.
The invention has the beneficial effects as follows: bidirectional hydraulic lock of the present invention, structure is simple, operationally by different filler openings and oil outlet discharge pressure oil, realizes the fluid flowing of different direction, efficiently easy to use, not fragile.Simultaneously when entering without pressure oil, this bidirectional hydraulic lock handle loop is locked, does not allow backflow fluid have flowing, safer.
Accompanying drawing explanation
Fig. 1 is bidirectional hydraulic lock structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, a kind of bidirectional hydraulic lock, comprises valve body 1, left spool 2, right spool 3, left push rod 4, right push rod 5 and piston 6, is provided with two valve pockets 12 in valve body 1, in valve pocket 12, be horizontally disposed with left spool 2 or right spool 3, described left spool 2 and right spool 3 are symmetrical arranged.
Piston 6 is provided with in the middle part of valve body 1, described piston 6 one end is connected with left spool 2 by left push rod 4, described piston 6 the other end is connected with left spool 3 by right push rod 5, the described valve pocket 12 being provided with left spool 2 is connected with oil outlet 8 with filler opening 7 by pipeline, the described valve pocket 12 being provided with right spool 3 is connected with oil outlet 10 with filler opening 9 by pipeline, described spool can block the pipeline between filler opening and oil outlet, be provided with the spring 11 be connected with valve body 1 in described left spool 2 or right spool 3, described pipeline can to piston 6 discharge pressure oil.
Bidirectional hydraulic lock of the present invention pins loop exactly, does not allow loop fluid have flowing, and hydraulic lock essence is made up of two Pilot operated check valves.While pressure oil flows to oil outlet 8 from filler opening 7, left push rod 4 promotes piston 6 and moves to right, and pushes right spool 3 open, realizes free flow between filler opening 9 and oil outlet 10; Vice versa, and when pressure oil flows to oil outlet 10 from filler opening 9, right push rod 5 promotes piston 6 and moves to left, and pushes left spool 2 open, realizes free flow between filler opening 7 and oil outlet 8.When filler opening 7 and filler opening 9 all do not have pressure oil to say people. this valve is in self-locking state.
In sum, bidirectional hydraulic lock of the present invention, structure is simple, operationally by different filler openings and oil outlet discharge pressure oil, realizes the fluid flowing of different direction, efficiently easy to use, not fragile.Simultaneously when entering without pressure oil, this bidirectional hydraulic lock handle loop is locked, does not allow backflow fluid have flowing, safer.
More than show and describe basic principle of the present invention, major character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
