Description
Technical field
It the utility model is related to machinery field, and in particular to a kind of fluid pressure type automatic reverse check valve.
Background technology
It is the valve being commonly used in industrial automation production that check valve, which is also known as check-valves, it can force fluid unidirectionally to flow
It is dynamic, prevent opposite direction flowing.Present check valve can only make one-directional fluid flow, but with the development of science and technology, have very much
Automation equipment needs the one-way flow of positive direction when working, it is also desirable to the one-way flow of opposite direction.
The content of the invention
The purpose of this utility model is aiming at defect existing in the prior art, there is provided one kind can rely on the hydraulic cutting change of current
The fluid pressure type automatic reverse check valve in dynamic direction.
Its technical solution is：Fluid pressure type automatic reverse check valve, including valve body, the valve body include the first valve chamber and the
Two valve chambers, first valve chamber connect the first spool, second valve chamber connect the second spool, first valve chamber with
Moveable block body is provided between second valve chamber, when the block body is located at the second spool end, the first valve chamber passes through the first valve
The action of the baffle of core is communicated with the second valve chamber；When the block body is located at the first spool end, the second valve chamber passes through the second spool
The action of baffle communicated with the first valve chamber, the block body both ends are respectively provided with beam hanger, and the valve body both ends are respectively provided with oil duct,
The beam hanger passes through the oil duct.
Further, first spool includes baffle, spring, fixed plate, flange, and one end of the baffle is equipped with bar
Part, is provided with spring on the rod piece, the spring supporting is in fixed plate and the centre of baffle, the other end of the baffle
It is spacing by flange.
Further, the beam hanger and the oil duct are clearance fit.
Further, the fixed plate is equipped with multiple through holes.
Further, the baffle is cone.
Compared with prior art, has the following advantages：Reasonable, simple in structure, reliable in action is designed, according to
The one-way flow of fluid positive and negative direction is realized by hydraulic drive, it is highly practical.
Brief description of the drawings
Fig. 1 is the structure chart of the utility model positive direction work；
Fig. 2 is the structure chart of the utility model opposite direction work.
1, valve body in figure, the 2, first valve chamber, the 3, second valve chamber, 4, oil duct, 5, beam hanger, 7, block body, 8, baffle,
9th, spring, 10, fixed plate, 11, rod piece, 12, flange, the 13, first spool, the 14, second spool.
Embodiment
With reference to Fig. 1, Fig. 2, fluid pressure type automatic reverse check valve, including valve body 1, the valve body 1 include 2 He of the first valve chamber
Second valve chamber 3, first valve chamber 2 connect the first spool 13, and second valve chamber 3 connects the second spool 14, described
Moveable block body 7 is provided between first valve chamber 2 and the second valve chamber 3, when the block body 7 is located at the second 14 end of spool, the
One valve chamber 2 is communicated by the action of the baffle of the first spool 13 with the second valve chamber 3；The block body 7 is located at 13 end of the first spool
When, the second valve chamber 3 is communicated by the action of the baffle of the second spool 14 with the first valve chamber 2, and 7 both ends of block body are respectively provided with oil
Bar 5,1 both ends of valve body are respectively provided with oil duct 4, and the beam hanger 5 passes through the oil duct 4；First spool 13 wraps
Baffle 8, spring 9, fixed plate 10, flange 12 are included, one end of the baffle 8 is equipped with rod piece 11, is installed on the rod piece 11
There is spring 9, the spring 9 is supported on the centre of fixed plate 10 and baffle 8, and the other end of the baffle 8 is spacing by flange 12；
The beam hanger 5 is clearance fit with the oil duct 4；The fixed plate 10 is equipped with multiple through holes；The baffle 8 is
Cone.
In use, the oil duct 4 at valve body both ends connects oil pump, to control beam hanger 5 to move up and down, when block body is moved on to close to first
During spool end, fluid can only pass through the second spool 14, by the pressure of fluid that baffle is open-top, and fluid is by the through hole in fixed plate
The first valve chamber 2 is flowed into, is then out.Since block body 7 blocks the first spool 13 during fluid opposite direction, the second valve chamber 3 can not be flowed into,
Second spool can not also flow into the second valve chamber 3 by the effect of baffle and flange.When block body is moved on to close to the second spool end, fluid
The first spool 13 can only be passed through, by the pressure of fluid that baffle 8 is open-top, fluid flows into the second valve by the through hole in fixed plate 12
Chamber 3, is then out.Since block body 7 blocks the second spool 14 during fluid opposite direction, the first valve chamber 2 can not be flowed into, the second spool leans on
The effect of baffle 8 and flange 12, can not also flow into the first valve chamber 2.
The structure and connection relation do not mentioned are common knowledge.
Above-described is only a preferred embodiment of the utility model, it is impossible to limits the model of the utility model implementation
Enclose, every equivalent change made according to present utility model application the scope of the claims and decoration, should all still fall within the utility model and cover
In the range of.
