Description
Technical field
The utility model is related to pressure-relief valve technical field, in particular to a kind of manufacture easy to process, repair and replacement side
Just split type super-pressure pressure-relief valve.
Background technology
The pressure relief device of domestic and international existing super-pressure is broadly divided into manual needle valve, gas or the needle-valve of hydraulic control.Manually, gas or
Hydraulic control is formed with many shortcomings, it is most apparent the defects of be that cannot reasonably control the size of initial sealing power and carry out wide scope
Adjusting, initial sealing power cross conference shorten needle service life, it is too small, the guarantor before extra high voltage system release cannot be played
Pressure acts on；Therefore, the service life of needle is extremely short in ultra-high voltage environment；In addition, speed during release is generally uncontrollable, release side
Formula is relatively simple；Pressure valve discharges high pressure after extra high voltage system pressurized operation, it is made to drop to the element of normal pressure, due to superelevation
Pressure element works under more than 100MPa high pressures, and inside and outside differential pressure is very big during release, high particularly in the initial instant of release
Hydraulic fluid stream can by section it is very small, flow velocity is very high, and impact force is very big, it is easy to make deformed element, in addition friction hair
Heat easily makes component wear；This brings problems in practice, even if some pressure relief devices can control release speed or release side
Formula, there is also the shortcomings of structure is excessively complicated, manufacture is of high cost and dismounting is difficult.
Chinese Patent Application No. is 201220038098.6, and patent name is the super-pressure automatically unloading with wear-compensating
Device；It is exactly in order to solve the above technical problems, still since its valve body is an overall structure, directly makes with needle cooperation
With, when valve body breaks down, entire valve body is needed replacing, since valve body is an overall structure, fabricates relative difficulty,
Replacement cost is high.
Invention content
The utility model aim is to provide a kind of manufacture easy to process, repair and replacement easily split type super-pressure release
Valve solves more than technical problem.
In order to realize above-mentioned technical purpose, reach above-mentioned technology requirement, technical solution is used by the utility model：
Split type super-pressure pressure-relief valve, including being connected on valve deck, and the valve body coordinated with needle；It is characterized in that：The valve body packet
Valve housing is included, be arranged on the valve body coordinated inside valve housing and with needle and is connected between valve housing and valve body
Valve body compression ring.
As preferred technical solution：First through hole and the second through-hole are provided on the valve housing.As preferred
Technical solution：It protrudes outside valve housing and is threaded on valve deck, the needle hole of middle section in described valve body one end
Cooperation is sealed between needle.
As preferred technical solution：Proper tolerances clearance fit is pressed between the valve body and valve housing.
As preferred technical solution：Be provided on the valve body the first liquid-inlet for being communicated with first through hole and
Second liquid import and the liquid outlet communicated with the second through-hole.
As preferred technical solution：First liquid-inlet and the entrance and liquid of second liquid import
The exit of outlet is both provided with conical seal (contact) face structure.
As preferred technical solution：The second liquid import and the first liquid-inlet and the center line of liquid outlet
To be vertically arranged after plane projection.
As preferred technical solution：The second liquid import is communicated with needle hole.
As preferred technical solution：The valve body compression ring is threadedly attached in valve housing, and compresses valve sheet
Body.
The beneficial effects of the utility model are：Split type super-pressure pressure-relief valve, compared with traditional structure：The valve body packet
Valve housing is included, be arranged on the valve body coordinated inside valve housing and with needle and is connected between valve housing and valve body
Valve body compression ring；Valve body is separately set, is composed of valve housing, valve body and valve body compression ring, not only fabricate compared with
It is convenient, and when local component wear, do not need to replace entire valve body, reduce use cost.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
In figure：1. valve deck, 2. needles, 3. valve housings, 4. valve bodies, 5. valve body compression rings, 3-1. first through hole, 3-2.
Second through-hole, the first liquid-inlets of 4-1., the import of 4-2. second liquids, 4-3. liquid outlets, 4-4. cone-shaped seal structures, 101.

Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings；
In the accompanying drawings：Split type super-pressure pressure-relief valve, including being connected on valve deck 1, and the valve body coordinated with needle 2；Institute
The valve body stated includes valve housing 3, the valve body 4 being arranged in valve housing 3 and is connected between valve housing 3 and valve body 4
Valve body compression ring 5；First through hole 3-1 and the second through-hole 3-2 are provided on the valve housing 3；It is set on the valve body 4
There are the first liquid-inlet 4-1 communicated with first through hole 3-1 and a second liquid import 4-2 and communicated with the second through-hole 3-2
Liquid outlet 4-3；The first liquid-inlet 4-1 and the entrance of second liquid import 4-2 and liquid outlet 4-3's
Exit is both provided with conical seal (contact) face structure 4-4；The conical seal (contact) face structure 4-4 plays the role of being oriented to liquid,
Also cutout is prevented；The second liquid import 4-2 and the center of the first liquid-inlet 4-1 and liquid outlet 4-3
To be vertically arranged after line plane projection；The second liquid import 4-2 is communicated with needle hole 101.
In actual use, the valve body is split structure, is combined by valve housing 3, valve body 4 and valve body compression ring 5
It forms；By proper tolerances clearance fit between the valve body 4 and valve housing 3, connection accuracy ensure that；The valve body
4 one end protrusion is in 3 outside of valve housing and is threaded on valve deck 1, is sealed between the needle hole 101 of middle section and needle 2
Cooperation.
The valve body compression ring 5 is threadedly attached in valve housing 3, and compresses valve body 4；After actually compressing also
There is a rotary freedom, there be a holding screw side, this hole is unilateral on valve housing 3 to bore a tapped through hole.Due to valve
Ontology 4 directly coordinates when using with needle 2, usually wears more serious, need to often replace, and only valve body compression ring 5 need to be removed, by valve
Ontology 4 is unscrewed by valve deck 1, by unloading valve body 4 on valve housing 3；Entire valve body structure is close, when local component wear, only
One of component is needed to change, when reducing use cost, and fabricating, component shape rule, processing is more convenient, essence
Spend higher.
Above-described embodiment is only intended to clearly illustrate the description that the utility model is made, and not to the limit of embodiment
It is fixed, to those of ordinary skill in the art, other various forms of variations can also be made on the basis of the above description
Or change, there is no necessity and possibility to exhaust all the enbodiments, and the obvious variation thus amplified out
Or among changing still in the scope of protection of the utility model.
