Description
Technical field
The present invention relates to a kind of valve mechanisms, are specifically related to a kind of high temperature and pressure dynamic sealing burnt gas valve.
Background technology
Two outlet hole site angles on the spool of certain changeover valve are 140 °, are circumferentially unevenly distributed, cause
Valve under high-temperature high-pressure fuel gas effect not only by larger axial force, while also by larger radial load, high temperature gas flow
Erosion increased dramatically frictional force between spool and housing, high-temperature fuel gas, which is also mingled with burning generation, can block bearing,
And warpage can easily be occurred, high-temperature high-pressure fuel gas so that spool belongs to cantilever design in rotation process by increasing bearing clearance
It is easily leaked into inside body from the spool of rotation and casing joint surface, miscellaneous equipment is caused to burn out.
Invention content
To solve the above problems, the present invention provides a kind of high temperature and pressure dynamic sealing burnt gas valves.Match by using spherical surface
The sealing structure being combined with needle roller support is closed, solves spool in rotary course high temperature high-pressure gas leakage problem.
The present invention is achieved by following technical solution.
A kind of high temperature and pressure dynamic sealing burnt gas valve, including the spool in housing and mounting shell body, described spool one end connects
Output shaft is connected to, the other end is provided with end cap, and fuel gas inlet and gas outlet, institute are respectively arranged on the end cap and housing
Stating setting on spool, there are two ventholes, and end cap one end is provided with support component, the valve between the housing and spool
On core graphite annulus is set with close to output shaft side.
The support component is made of retainer and needle roller, and wherein retainer is the circular ring shape to match with housing and spool
Structure, needle roller are evenly arranged along retainer circumferencial direction.
It is gap-matched between the support component and housing and spool.
The spool is mating spherical surfaces with graphite annulus.
The two venthole angles set on the spool are 140 °.
The beneficial effects of the invention are as follows：
The present invention, into movable sealing structure, solves spool and exists by using the graphite annular of support component combination mating spherical surfaces
Rotary course high temperature high-pressure gas leakage problem, avoids result in miscellaneous equipment and burns out.After the movable sealing structure, gas valve
Door is by the ground heat run of multiple high temp high-pressure gas, and leakage is not present in spool in rotation process at output shaft, using good.

Specific embodiment
Technical scheme of the present invention is further described, but claimed range is not limited to reference to embodiment attached drawing
In described.
As shown in Figure 1, a kind of high temperature and pressure dynamic sealing burnt gas valve, including the spool 4 in housing 1 and installation housing 1, institute
State 4 one end of spool and be connected with output shaft 6, the other end is provided with end cap 7, be respectively arranged on the end cap 7 and housing 1 combustion gas into
Mouthfuls 9 and gas outlet 8, there are two ventholes 10 for setting on the spool 4, and end cap 7 is located between the housing 1 and spool 4
One end is provided with support component, and close 6 side of output shaft is set with graphite annulus 5 on the spool 4.It is set on the spool 4
Two ventholes 10 are mutually perpendicular to.Using the technical program, 4 left end of spool is using support component as support, and spool right end is with stone
Black ring 5 forms fitted seal, and the position that output shaft 6 rotates under the action of extraneous torque, by changing spool 4 controls spool 4
The aperture of upper venthole 10 and gas outlet 8 on housing 1.Full of under the conditions of high-temperature fuel gas inside the spool 4, spool 4 by
Axial force it is certain, the size for the lateral force being subject to changes with direction with the variation of aperture.By using support component knot
The graphite annulus 5 for closing mating spherical surfaces forms movable sealing structure, solves spool in rotary course high temperature high-pressure gas from output shaft
Locate leakage problem, avoid result in miscellaneous equipment and burn out.After the movable sealing structure described in the technical program, burnt gas valve warp
The heat run of multiple high-temperature high-pressure fuel gas ground is crossed, leakage is not present in spool 4 in rotation process at output shaft, using good.
As shown in Fig. 2, the support component is made of retainer 3 and needle roller 2, wherein retainer 3 is and housing 1 and spool
2 cirque structures to match, needle roller 2 are evenly arranged along 3 circumferencial direction of retainer.Using the technical solution, pass through retainer 3
Support component is formed with needle roller 2, effective support is formed to spool 4, can be rotated in housing 1 by 2 spool 4 of needle roller.It is described
Through-hole is additionally provided between per two adjacent needle rollers 2, is kept inside and outside needle roller 2 beyond arc surface inside and outside retainer 3, guarantee
There are gaps between frame 3 and housing 1 and spool 4, are not only advantageous to spool 4 and are rotated in housing 1, and can preferably ensure to burn
Generation blocks the gap between support component.
In order to avoid burning generation blocks support component, gap is used between the support component and housing 1 and spool 4
Cooperation；That is the periphery of the inside of needle roller 2 and spool 4 is clearance fit, and the outside of needle roller 2 is gap with the inner headed face of housing 1
Cooperation can effectively prevent burning generation to block the gap between needle roller 2 and retainer 3, to keep rotary valve in this way
The normal operation of door.
As shown in figure 3, the spool 4 is mating spherical surfaces with graphite annulus 5.Since spool 4 is produced by high-temperature high-pressure fuel gas
It under the action of raw out-of-balance force, glances off, passes through the mating spherical surfaces spool 4 and graphite between spool 4 and graphite annulus 5
Enough contacts area are kept between ring 5 in a circumferential direction, normal pressure is generated on spherical surface by the pressure of high-temperature fuel gas, is made
Sealing state is kept between spool 4 and graphite annulus 5, so as to ensure that high-temperature fuel gas will not leak at output shaft.Seal pressure with
The pressure size adjust automatically of high-temperature fuel gas, forms presser sensor formula movable sealing structure.
Two 10 angles of venthole set on the spool 4 are 140 °.
