The present invention relates to a kind of plunger valve cast with sealing compensation, including valve cast, support ring, piece, sealing ring, pressure ring are slidingly sealed, support ring is installed in the middle part of valve cast, and pressure ring is cylindrical shape, one end has flange, the other end is annulus, and pressure ring is installed on valve cast bottom by screw, and pressure ring flange is equipped with valve cast and is slidingly sealed piece, pressure ring flange excircle is equipped with rectangular channel, sealing ring is equipped with rectangular channel, piece is slidingly sealed and is fitted in by flange on pressure ring, and cover sealing ring.By the grooving on pressure ring and install sealing ring additional, provide compensation to be slidingly sealed piece by sealing ring, realize the double-layer seal to plunger valve.For the present invention in the case of ensureing that valve cast component movement is normal, raising is slidingly sealed ability, the generation for the fuel injection event that leaks air after reduction long-time use, while improves the reliability of plunger valve.
Description
Technical field
The invention belongs to fluid technique field, and in particular to a kind of plunger valve cast with sealing compensation.
Background technology
Plunger valve cast is mostly installed at plus oil transportation is controlled inside valve, and movement cooperation is carried out with valve body.For controlling
Oiling and oil transportation on aircraft fuel oil pipeline processed, such device frequency of use during aircraft works is very frequent, should open
Flexibly, it is oriented to and stablizes, meets to close tight requirement again, it is impossible to produce leakage.
Existing plunger valve cast generally by valve cast 1, support ring 2, be slidingly sealed piece 3 and pressure ring 4 forms, pressure ring 4 is
Flat, on valve cast 1,1 bottom of valve cast is equipped with spring mounting seat, for installing spring, produces spring force, makes column
Fill in valve cast and produce relative motion with valve body, as shown in Figure of description 1.Its there are the problem of have：1 center of gravity of valve cast is leaned on
On, stability is poor, easily produces clamping stagnation, is slidingly sealed piece 3 and is fitted in the cylindrical of pressure ring 4 by flange, after long-time use, bullet
Property dies down, and causes to be slidingly sealed between piece 3 and valve body having the gap, so as to cause valve gas leakage or oil spout.
The content of the invention
In view of the deficiencies of the prior art, it is an object of the invention to provide a kind of plunger valve with sealing compensation
Body.
Technical scheme：A kind of plunger valve cast with sealing compensation, including valve cast 1, support ring
2nd, piece 3, sealing ring 4, pressure ring 5 are slidingly sealed, support ring 2 is installed on the middle part of valve cast 1, and pressure ring 5 is cylindrical shape, and one end has convex
Edge, the other end are annulus, and pressure ring 5 is installed on 1 bottom of valve cast by screw, and 5 flange of pressure ring is equipped with valve cast 1 and is slidingly sealed
Piece 3,5 flange excircle of pressure ring are equipped with rectangular channel, are equipped with sealing ring 4 in rectangular channel, are slidingly sealed piece 3 and are fitted in pressure by flange
On ring 5, and cover sealing ring 4.
The above-mentioned piece 3 that is slidingly sealed covers 1/3~1/2 sealing ring.
Above-mentioned 3 material of piece that is slidingly sealed is fluoroplastics.
Above-mentioned 1 material of support ring is fluoroplastics.
Beneficial effects of the present invention：Improved valve cast, moves up valve cast center of gravity, strengthens the stabilization in motion process
Property, the structure of fluting installation sealing ring on pressure ring, slides the fluoroplastics after long-time use with the decrement of sealing ring close
Mounting provides compensation, strengthens the sealing performance of plunger valve, the generation for the fuel injection event that leaks air after reduction long-time use, together
The reliability of Shi Tigao plunger valve.

Embodiment
The present invention is described in further detail with reference to Figure of description.
A kind of plunger valve cast with sealing compensation, including valve cast 1, support ring 2, be slidingly sealed piece 3, sealing
Circle 4, pressure ring 5, support ring 2 are installed on the middle part of valve cast 1, and pressure ring 5 is cylindrical shape, and one end has flange, and the other end is annulus, pressure
Ring 5 is installed on 1 bottom of valve cast by screw, and 5 flange of pressure ring is equipped with valve cast 1 and is slidingly sealed piece 3, and 5 flange of pressure ring is cylindrical
Week is equipped with rectangular channel, is equipped with sealing ring 4 in rectangular channel, is slidingly sealed piece 3 and is fitted in by flange on pressure ring 5, and cover close
Seal 4, as shown in Figure 2.
The above-mentioned piece 3 that is slidingly sealed covers 1/3~1/2 sealing ring.
The above-mentioned piece 3 and 1 material of support ring of being slidingly sealed is fluoroplastics.
The course of work is as follows：
Support ring is installed in the middle part of valve cast, plays the stability in guiding role guarantee plunger valve motion process, together
When fluoroplastics support ring smoother, frictional force is small, wearability is fabulous, sealing ring is installed in the groove that pressure ring is held successfully, according to beating
Open the size selection suitable sealing ring of decrement of pressure.Fluoroplastics are slidingly sealed piece to be connected with plunger valve cast by pressure ring
Together, wherein fluoroplastics just wrap up sealing ring after being slidingly sealed piece flange.
Mounted plunger valve cast is installed in valve body, is opened and closed in valve by plunger valve cast
During.Support ring is played to be oriented to well and used, and fluoroplastics are slidingly sealed piece and play good sealing function, there is certain compression
The sealing ring of amount can provide compensation for the piece that is slidingly sealed after long-time use.Ensure that fluoroplastics are slidingly sealed piece and remain to living
Gate housing fits closely, so as to avoid the generation for the fuel injection event that leaks air after plunger valve long-time use.
Pressure of the present invention in pipeline sets the decrement of sealing ring and fluoroplastics to be slidingly sealed the thickness of piece, passes through
Cooperation with valve body realizes that movement is flexible, seals tight purpose.
The present invention plays guiding role by support ring, while the mounting base of valve cast is cancelled, and moving to inside pressure ring makes
The decentralization of whole plunger valve.Ensure the stability in plunger valve motion process, while fluoroplastics support ring relatively light
It is sliding, frictional force is small, wearability is fabulous, sealing ring is installed in the groove that pressure ring is held successfully, and compression is selected according to the size for opening pressure
Measure suitable sealing ring.Fluoroplastics are slidingly sealed piece to link together by pressure ring and plunger valve cast, wherein fluoroplastics are slided
Sealing ring is wrapped up just after dynamic sealing piece flange.The sealing ring of certain decrement can be being slidingly sealed after long-time use
Piece provides compensation and ensures its leakproofness.
