Abstract
The utility model belongs to the field of one-way valves and discloses an overpressure automatic exhaust one-way valve. The overpressure automatic exhaust one-way valve comprises a shell in a steel structure form and a valve plate component, wherein a transmission part which is made of stainless steel is arranged between the shell and the valve plate component; a linear bearing is arranged in the transmission part, so the start pressure of the valve plate component is ensured; and a high-quality anti-rusting paint layer is sprayed on an exposed part of the shell, so the overpressure automatic exhaust one-way valve is resistant to rusting, and the service life is prolonged.
Description
Technical field
The utility model relates to the one-way valve field, relates in particular to a kind of superpressure automatic vent one-way valve that is used for the permanent refuge chamber exhaust duct in colliery.
Background technique
Present similar products of the prior art mainly comprise: one-way valve and FCS250 superpressure exhaust valve.
One-way valve structures: form by housing, valve plate and the axis of guide.Housing, valve plate adopt foundry goods.Generally be used for drainage pipe.The one-way valve shortcoming: housing, valve plate adopts foundry goods, and profile is clumsy, and breakout pressure is big.And the corrosion resistant degree is low.
FCS250 superpressure exhaust valve structure: form by housing, valve plate, lever, weight etc.Housing, valve plate, lever etc. adopt aluminium and aluminum alloy.Reach adjustment breakout pressure function through regulating the weight position.Breakout pressure is generally at 30-50Pa.Require the weight vertical in the time of installation.FCS250 superpressure exhaust valve shortcoming: aluminium casing, valve plate, lever etc. are not suitable for mine and use.Breakout pressure is little, does not satisfy permanent chamber requirement.The installation validity is high, is difficult to guarantee.
The model utility content
In order to solve the problems of the technologies described above, the purpose of the utility model is to provide a kind of can guarantee breakout pressure, rust stable superpressure automatic vent one-way valve.
The complete skill scheme of the utility model is; A kind of superpressure automatic vent one-way valve; Comprise a housing and valve board assembly, said valve board assembly is arranged on the inboard of said housing, interts on said housing and the valve component axial location to be provided with transmission part; The joint of said transmission part and said housing is provided with linear bearing; The outside of said housing also is provided with an outer end cover, and said outer end is set in an end of said transmission part, and said outer end cover also is provided with a spring with the joint of said transmission part; Said outer end puts and also is provided with a harness cord, and an end of said harness cord passes said outer end cover and is connected with the end of said transmission part.
Said housing is a Steel Sheel.
Said valve board assembly is the valve board assembly of arch steel structure.
Said housing and said valve board assembly joint are provided with a seal ring.
The exposed parts of said housing is coated with rust preventive coating.
Therefore the utility model has following beneficial effect with present compared with techniques:
Adopt linear bearing in the utility model in the transmission part, protected the breakout pressure of valve plate, the housing of steel structural form; Beautiful shape, the steel structural form valve plate guarantees breakout pressure; The housing exposed parts is coated with rust preventive coating; The high-quality rust proof paint guarantees corrosion resistant under sour wet environment, and the stainless steel transmission part guarantees proper functioning under sour wet environment.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:
Fig. 1 is the utility model structural representation.
Embodiment
To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.
Embodiment 1:
A kind of superpressure automatic vent of present embodiment one-way valve, as shown in Figure 1, comprise the housing 1 of a steel structural form and the valve board assembly 2 of steel structural form; Valve board assembly 2 is arranged on the inboard of housing 1; Valve component 2 is provided with a seal ring 3 with the joint of housing 1, interts on housing 1 and valve component 2 axial location to be provided with transmission part 4, and transmission part 4 is provided with linear bearing 5 with the joint of housing 1; The outside of housing 1 also is provided with an outer end cover 6; Outer end cover 6 is located at an end of transmission part 4, and outer end cover 6 also is provided with a spring 7 with the joint of transmission part 4, also is provided with a harness cord 8 on the outer end cover 6; One end of harness cord 8 passes outer end cover 6 and is connected with the end of transmission part 4, and the exposed parts of housing 1 is coated with the high-quality rust preventive coating.
Therefore, the housing of employing steel structural form in the utility model, beautiful shape; The valve plate of steel structural form has guaranteed breakout pressure, and stainless transmission part has guaranteed proper functioning under sour wet environment simultaneously; Be provided with the breakout pressure that linear bearing has guaranteed valve plate in the transmission part; The housing exposed parts is coated with the high-quality rust proof paint, makes more corrosion resistant of whole parts, has increased working life.
More than technological scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper the utility model embodiment's principle and mode of execution are set forth, above embodiment's explanation only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.
