Description
Technical field
The present invention relates to hydraulic valve technical field, in particular to a kind of flat valve.
Background technology
Flat valve is that conventional in hydraulic system matches somebody with somebody flow-control element, is opened in pump work with the back and forth movement of plunger
Open and close.Compared with valve plate distribution, flat valve reduces friction pair (cylinder body and valve plate or cylinder body and pintle), from
And reduce leakage and the wear problem of friction pair, there is good sealing, it is thus possible to work in a high voltage state, especially
It is adapted to apply in water hydraulic.
The structure of conventional flat valve is to realize flow using two check valves or more than two check valves at present, still
Check valve is more, and leakage is also bigger, and efficiency is also lower.
Therefore, the problem of flat valve is made up of multiple check valves and easily revealed in the prior art be present.
The content of the invention
It is a primary object of the present invention to provide a kind of flat valve, to solve flat valve of the prior art by multiple unidirectional
Valve is formed and easy leakage problem.
To achieve these goals, the invention provides a kind of flat valve, including valve body, the first end cap, the second end cap and
Check valve, the first liquid-through hole is offered along the bearing of trend of valve body on valve body, the first end of the first end cap and the first liquid-through hole is close
Envelope connection, first end, which covers, offers the first inlet opening, and the first inlet opening is stepped hole, the second end cap in the first liquid-through hole the

Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
It is noted that described further below is all exemplary, it is intended to provides further instruction to the application.It is unless another
Indicate, all technologies used herein and scientific terminology are with usual with the application person of an ordinary skill in the technical field
The identical meanings of understanding.
It is made up of and easy leakage problem multiple check valves to solve flat valve of the prior art, the invention provides one
Kind flat valve.
As shown in figure 1, flat valve includes valve body 10, the first end cap 20, the second end cap 30 and check valve 40, edge on valve body 10
The bearing of trend of valve body 10 offers the first liquid-through hole, and the first end of the first end cap 20 and the first liquid-through hole is tightly connected, and first
The first inlet opening 21 is offered on end cap 20, the first inlet opening 21 is stepped hole, and the second end cap 30 is in the second of the first liquid-through hole
End is tightly connected, and offers the first fluid hole 31 on the second end cap 30, the outer peripheral face of check valve 40 is interior with the first inlet opening 21
Dynamic sealing is formed between wall, the first end end face of check valve 40 passes through between the step surface of the first spring 50 and the first inlet opening 21
Connection, apical grafting between the second end of check valve 40 and the second end cap 30, on valve body 10 the first end cap 20 and the second end cap 30 it
Between offer the second fluid hole 11 perpendicular to the first liquid-through hole.The side of the second end cap 30 of flat valve and radial plunger pump or horse
Up to connection, when radial plunger pump or motor imbibition, medium enters from the first inlet opening 21, and check valve 40 is opened, due to unidirectional
The apical grafting of 40 and second end cap of valve 30, sealing structure is formed therebetween, thus medium is directly entered first from the outflow of check valve 40
Fluid hole 31 is then into radial plunger pump or motor；When radial plunger pump or motor hydraulic fluid, due to check valve 40
Interaction medium can not form dynamic sealing, thus medium meeting between adverse current and the inwall of the outer peripheral face of check valve and the first inlet opening 21
Check valve 40 is promoted to compress the first spring 50 to the lateral movement of the first end cap 20 1 so that the end cap 30 of check valve 40 and second is de-
Open, medium enters cavity between valve body 10 and check valve 40 and simultaneously flowed out from the second fluid hole 11, so as to complete an imbibition and
The flow of hydraulic fluid, complete flow.The flat valve of the present invention only used a check valve 40, by check valve 40 and valve body 10,

So that the flat valve of the present invention has the characteristics of small leakage rate, efficiency high.
Preferably, the second fluid hole 11 along valve body 10 it is circumferentially-spaced be symmetrically arranged with it is multiple.Due to the second fluid hole 11
Along valve body 10 it is circumferentially-spaced be symmetrically arranged with it is multiple, thus during hydraulic fluid, medium enter valve body 10 and check valve 40 it
Between cavity when enable to the radial force of check valve 40 to balance, so as to avoid causing due to the force unbalance of check valve 40
Frictional force increases between the inwall of the inlet opening 21 of check valve 40 and first, and then reduces check valve 40 along the first inlet opening 21
Frictional force when wall slides, the service life of check valve 40 is improved, meanwhile, the second fluid hole 11 is along the circumferentially-spaced right of valve body 10
Title also disclosure satisfy that flat valve carries out matching somebody with somebody liquid to multiple branch roads when being provided with multiple.Second fluid hole 11 as shown in Figure 1 is pair
Claim ground that the embodiment of two is set.
As shown in figure 1, pass through spiral shell between the first end cap 20 and the first liquid-through hole, between the second end cap 30 and the first liquid-through hole
Line connects.Due to being connected through a screw thread between the first end cap 20 and the first liquid-through hole, between the second end cap 30 and the first liquid-through hole,
Thus can easily be installed between the first end cap 20 and the first liquid-through hole, between the second end cap 30 and the first liquid-through hole and
Dismounting so that flat valve of the invention has the characteristics of being easily assembled to and dismantling.
Preferably, the junction of the junction of the first end cap 20 and the first liquid-through hole, the first end cap 20 and the first liquid-through hole
Scribble fluid sealant.Pass through the connection in the junction of the first end cap 20 and the first liquid-through hole, the first end cap 20 and the first liquid-through hole
Place applies fluid sealant, so as to increase between the first end cap 20 and the first liquid-through hole, between the second end cap 30 and the first liquid-through hole
Sealing effectiveness, reduce leakage.
As depicted in figs. 1 and 2, check valve 40 includes check valve valve body 41, check valve end cap 42 and second spring 43, unidirectionally
Dynamic sealing is formed between the inwall of the outer peripheral face of valve body 41 and the first inlet opening 21, the first end end face of check valve valve body 41 leads to
Cross between the step surface of the first spring 50 and the first inlet opening 21 and connect, the second end of check valve valve body 41 and the second end cap 30 it
Between apical grafting, offer the second liquid-through hole along the bearing of trend of check valve valve body 41 on check valve valve body 41, opened on check valve end cap 42
Provided with the second inlet opening 421, the liquid-through hole of check valve end cap 42 and second is tightly connected close to one end of the first end cap 20, and second
Liquid-through hole is arranged to stepped hole, the side of second spring 43 and the step surface of the second liquid-through hole close to the side of the second end cap 30
Connection, is provided with Ball valve 44 between the opposite side and check valve end cap 42 of second spring 43, the diameter of Ball valve 44 is more than the
The diameter of two inlet openings 421, apical grafting between Ball valve 44 and check valve end cap 42.Pass through the end cap 20 of check valve valve body 41 and first
