Description
Technical field
The application is related to a kind of valve, and in particular to a kind of gas chamber gas bleeding valve.
Background technology
In the prior art, valve generally use is dissipated with coal gas side at the top of its emergency diffusion device of dry type Wiggins gas chamber "
O " types sealing ring is sealed to the mating surface of valve cylinder and bonnet, and its sealing ring is embedded in a steel plate, when using for a period of time
Afterwards, due to reasons such as ageing of rubber or laying dusts, easily cause poorly sealed and gas leak phenomenon occur, potential safety hazard be present.
The content of the invention
The purpose of the application is：In view of the above-mentioned problems, a kind of sealing effectiveness of the application proposition is more preferable, safer gas chamber
Use gas bleeding valve.
The technical scheme of the application is：
A kind of gas chamber gas bleeding valve, including：
Its top carries the valve cylinder of coal gas diffusion mouth, and
It is pressed on the bonnet on the coal gas diffusion mouth top；
The smooth stainless steel coil in upper surface is fixedly installed at the opening's edge of the coal gas diffusion mouth, the bottom of the bonnet is consolidated
Surely it is provided with the rubber gasket for the sheet being engaged with the stainless steel coil.
The application is on the basis of above-mentioned technical proposal, in addition to following preferred scheme：
Also include upright guide rail that is mutually fixed with the valve cylinder and being located at outside the valve cylinder, be fixed with the bonnet
The sliding block being connected is slid vertically with the upright guide rail.
The upright guide rail is provided with least two, and the upright guide rail is distributed uniformly and circumferentially in the valve
Cylinder periphery.
Also include vertical guide pin bushing that is mutually fixed with the valve cylinder and being located inside the valve cylinder, be fixed with the bonnet
The vertical guide pillar being connected is slid vertically with the vertical guide pin bushing.
The vertical guide pin bushing and the valve cylinder are coaxially arranged.
The rubber gasket in the vertical direction shelters from the coal gas diffusion mouth completely.
The rubber gasket is to be fixedly connected on the bonnet bottom by pressing plate and bolt.
The bonnet is steel plate material.
The application has the advantages that：Compared with traditional diffusion valve for coal gas cabinet, the application uses rubber seal
Sealing device its sealing of pad and stainless steel coil composition is tighter, can guarantee that need not coal gas diffusion when valve seal it is reliable
Property.
Brief description of the drawings
The application is described further with specific embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the longitudinal sectional drawing of gas chamber gas bleeding valve in the embodiment of the present application；
Fig. 2 is Fig. 1 A-A to profile.
Wherein：1- valve cylinders, 1a- coal gas diffusion mouths, 2- bonnets, 3- stainless steel coils, 4- rubber gaskets, 5- upright guide rails,
The vertical guide pin bushings of 6-, the vertical guide pillars of 7-, 8- sliding blocks, 9- pressing plates.
Embodiment
Figures 1 and 2 show that a preferred embodiment of this gas chamber gas bleeding valve of the application, with traditional coal gas
Cabinet is that it also includes valve cylinder 1 and bonnet 2 with gas bleeding valve identical, and the wherein top of valve cylinder 1 carries coal gas diffusion mouth 1a；
Bonnet 2 is steel plate material, and it is pressed in the coal gas diffusion mouth 1a tops at the top of valve cylinder 1 by self gravitation.
The key improvements of the present embodiment are：Stainless steel coil 3 is fixedly installed at coal gas diffusion mouth 1a opening's edge, bonnet 2
Bottom is fixedly installed the rubber gasket 4 being engaged with stainless steel coil 3.The upper surface of stainless steel coil 3 has necessarily smooth
Degree, rubber gasket 4 is monoblock type laminated structure, not the O-ring with intermediate throughholes.
During practical application, the bottom of valve cylinder 1 is connected with gas piping, and bonnet 2 is pressed in the top of stainless steel coil 3 by self gravitation
And block coal gas diffusion mouth 1a, when gas pressure is higher in valve cylinder 1 needs to diffuse, bonnet 2 is by coal gas in valve cylinder
Rise to uplifting pressure, mobile space, coal gas diffusion mouth 1a quilts are formed between the stainless steel coil 3 at bonnet 2 and the top of valve cylinder 1
Open, the coal gas blocked originally in valve cylinder 1 is escaped by the space (coal gas diffusion mouth 1a) between bonnet 2 and stainless steel coil 3
Shed.After gas pressure is reduced to certain value in valve cylinder 1, bonnet 1 falls back to original position, the bottom of bonnet 1 under gravity
Rubber seal 4 be pressed in again the top of stainless steel coil 3, with stainless steel coil 3 formed tight seal, ensure coal gas not loss.
In order to prevent mobile generation off normal of the bonnet 2 under self gravitation and gas pressure effect, the present embodiment is in valve cylinder 1
Periphery more upright guide rails 5 have been fixedly installed, these upright guide rails 5 are distributed uniformly and circumferentially in the periphery of valve cylinder 1, and
Being respectively connected with every upright guide rail 5 can be locked along the sliding block 8 that guide rail slides vertically, sliding block 8 by screw and bonnet 2.
Moving up and down for bonnet 2 is guided with this.
In order to further prevent bonnet 2 from shifting when vertically movable, the present embodiment is coaxially fixed with one in valve cylinder 1
Vertical guide pin bushing 6, it is fixedly connected on bonnet 2 and slides vertically the vertical guide pillar 7 being connected with the vertical guide pin bushing 6.
Above-mentioned rubber gasket 4 has the horizontal area bigger than coal gas diffusion mouth 1a, and rubber gasket 4 is vertical
Coal gas diffusion mouth 1a is sheltered from completely on direction, such as Fig. 1.
Above-mentioned rubber gasket 4 is fixedly connected on the bottom of bonnet 2 particular by pressing plate 9 and bolt, and pressing plate 9 is pressed
In the bottom of rubber gasket 4, the vertical locking pressure plate 9 of bolt and bonnet 2 and rubber gasket 4 is clamped tightly at pressing plate 9 and valve
Between lid 2.
Because rubber gasket 4 is monoblock type laminated structure, so itself and the settable many fixed connection points of bonnet 2, from
And make it that the connective stability of rubber gasket 4 and bonnet 2 is higher, the aging crushed element of rubber gasket 4 after long-term use
Its exterior rim position is concentrated mainly on, and the part pressed on rubber gasket 4 with stainless steel coil 3 will not be a greater impact.
And rubber gasket 4 and stainless steel coil 3 coordinate jointly, sealing is tighter.
" fixation " described in the application, including it is directly fixed and indirectly fixed.
Certainly, above-described embodiment is only the technical concepts and features for illustrating the application, and its object is to make people much of that
Solution present context is simultaneously implemented according to this, and the protection domain of the application can not be limited with this.It is all according to the application major technique
The equivalent transformation or modification that the Spirit Essence of scheme is done, should all cover within the protection domain of the application.
