Description
Technical field
The utility model is related to a kind of check valve, more particularly to a kind of super-pressure check valve.
Background technology
Hydraulic system>32MPa can be described as super-pressure, under superelevation pressure condition, be originally used for the hydraulic valve of normal pressure system not
Can be competent, diamond press system hyperpressure largely uses check valve, currently, Buddha's warrior attendant in 90MPa or so in high-pressure system
The check valve used in stone press system improves the hardness of material and strong still on the basis of low pressure check valve, by heat treatment
It spends to realize, service life is short, sealing leak, compels it and needs a kind of novel check valve, solves the problems, such as service life and sealing.And
And the prior art, on super-pressure check valve, no independent structure is upper domestic usually with inserted mode knot due to being designed in super-pressure
Structure, valve body are integrated morphology, and upper extremely complex in super-pressure oil system arrangement, valve body processing difficulties, manufacturing cost is very high, and
Maintenance difficult.
Utility model content
The purpose of this utility model is in view of the above problems and insufficient, provides that a kind of sealing performance is reliable, structure
Compact super-pressure check valve.
To achieve the above object, technical solution used by the utility model is：A kind of super-pressure check valve, including valve body
And end cap, the end cap are connect with the valve seal, are equipped with pressing sleeve, guide sleeve and valve in the body cavity successively from left to right
Seat, the pressing sleeve, guide sleeve are connected to valve base cavity, spring and ball sealer are equipped in the guide sleeve, the ball sealer is in the bullet
Top pressure seals on the valve seat and by the valve base cavity under the top pressure of spring, and the spring one end top pressure is in the pressing sleeve inner end
On face, other end top pressure is sealed between the valve seat and valve body cavity bottom surface by gasket on the ball sealer,
Inner cavity is connect by first medium runner with high pressure oil inlet, and the body cavity passes through second medium runner and low pressure oil export
Connection.
In the above-mentioned technical solutions, the pressing sleeve is interference fitted with the body cavity.
In the above-mentioned technical solutions, the gasket is copper packing.
In the above-mentioned technical solutions, the ball sealer and valve seat are all made of hard alloy and are made, and the ball sealer and
The ground processing of valve seat.
The utility model has the beneficial effects that：The utility model realizes self sealss by sealing ball and spring, not easy to wear
Sealing element, sealed reliable, being carried out on seal receptacle ball sealer top pressure by spring of the utility model super-pressure check valve are close
Envelope, it is simple in structure, convenient for making, and spring and ball sealer are mounted in guide sleeve, compact-sized, compact is easy to maintain.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model.
Figure label：1 is end cap, and 2 be pressing sleeve, and 3 be valve body, and 4 be guide sleeve, and 5 be spring, and 6 be ball sealer, and 7 be valve seat, 8
It is first medium runner for gasket, 9,10 be second medium runner.
Specific implementation mode
It should be noted that：Belong in the description of the present invention, "center", "upper", "lower", " left side " " right side ", "inner",
Either position relationship is orientation based on ... shown in the drawings or position relationship in the orientation of the instructions such as "outside", is merely for convenience of describing
The utility model and simplifying describes, rather than indicate or imply signified device or parts must have particular orientation, with
Specific azimuth configuration and operation, therefore should not be understood as limiting the present invention.In addition, belong to " first ", " second ",
" third ", " the 4th " are used for description purposes only, and should not be understood as indicating or implying relative importance.
In the description of the present invention, it should be noted that unless otherwise expressly provided and limit, term " installation ",
" connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally connect
It connects；It can be directly connected, it can also be indirectly connected through an intermediary.For the ordinary skill in the art, may be used
Understand the concrete meaning of above-mentioned term in the present invention with concrete condition.
Below in conjunction with the accompanying drawings and specific implementation mode is described in further detail the utility model：
Embodiment 1：As shown in Figure 1, a kind of super-pressure check valve, including valve body 3 and end cap 1, end cap 1 are sealed with valve body 3
It connects, intracavitary is equipped with pressing sleeve 2, guide sleeve 4 and valve seat 7 successively from left to right in valve body 3, and pressing sleeve 2, guide sleeve 4 and 6 inner cavity of valve seat connect
Logical, pressing sleeve 2 is interference fitted with 3 inner cavity of valve body, spring 5 and ball sealer 6 is equipped in guide sleeve 4, ball sealer 6 is under the top pressure of spring 5
For top pressure on valve seat 6 and by 6 bore seal of valve seat, it is close that pressure of the ball sealer 6 in 3 inner cavity of spring and valve body declines 7 inner cavity of valve seat
Envelope.5 top pressure of spring on 2 inner face of pressing sleeve, lead on ball sealer 6 between 3 cavity bottom surface of valve seat 7 and valve body by other end top pressure
The sealing of gasket 8 is crossed, inner cavity is connect by first medium runner 9 with high pressure oil inlet, and 3 inner cavity of valve body passes through second medium stream
Road 10 is connect with low pressure oil export.Ball sealer 6 and valve seat 7 are all made of hard alloy and are made, and the service life can reach 3 years or more, and
Ball sealer 6 and the ground processing of valve seat 7, sealing is tight, can reach pressure drop in 24 hours<2%, sealed reliable.
Gasket 8 is copper packing, and pressing sleeve 2 is realized copper packing compressive strain by compressing guide sleeve 4, valve seat 6 after the completion of assembly
Sealing, and pressing sleeve 2 and 3 inner cavity of valve body are interference fit, and the phenomenon that will not being reversed, sealed reliable will not leak.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
