Abstract
The utility model discloses a can assist shutoff ware that gas relief valve area pressure was changed, its characterized in that: including the blind flange, the blind flange is installed in the bleed valve upper end on the pipeline diffuse nozzle stub, the mid-mounting of blind flange has the shutoff pole, the bottom of shutoff pole is installed and is diffused nozzle stub inner wall seal complex transition nozzle stub with the pipeline, the middle part of transition nozzle stub is equipped with the draw-in groove, the card is equipped with seal assembly in the draw-in groove, violently straight dead lever is installed on the top of shutoff pole, the fixed cardboard that is used for the chucking dead lever is installed to the both sides of blind flange. The utility model has reasonable structure design, and the valve (gasket) can be safely replaced without stopping air, thereby reducing the influence of air stopping on users; economic benefit, and reduced loss of fuel gas emission.
Description
The technical field is as follows:
the utility model relates to a gas diffuses valve and changes the field, mainly relates to a can assist gas to diffuse stopper that valve area was pressed and is changed.
Background art:
because gas pipeline diffuses the valve and uses for a long time, and a lot of emergence damage, leak, need change valve (gasket), prior art is through stopping gas change, and it is extravagant to seriously influence user's gas and cause a large amount of natural gas evacuation, wastes time and energy, can not satisfy the operation requirement.
The utility model has the following contents:
the utility model discloses the purpose is exactly in order to compensate prior art's defect, provides a can assist gas diffusion valve area and take the plugging device of change, and valve (gasket) is changed safely under the condition of not stopping gas, simple accurate, and economic benefits has reduced the loss that the gas was diffused.
The utility model discloses a realize through following technical scheme:
the utility model provides a can assist shutoff ware that gas relief valve area pressure was changed which characterized in that: including the blind flange, the blind flange is installed in the bleed valve upper end on the pipeline diffuse nozzle stub, the mid-mounting of blind flange has the shutoff pole, the bottom of shutoff pole is installed and is diffused nozzle stub inner wall seal complex transition nozzle stub with the pipeline, the middle part of transition nozzle stub is equipped with the draw-in groove, the card is equipped with the polyurethane stick sealing member in the draw-in groove, the dead lever of violently straight is installed on the top of shutoff pole, the fixed cardboard that is used for the chucking dead lever is installed to the both sides of blind flange.
And the flange cover is provided with fixed mounting holes which are matched with the mounting holes on the air relief valve body.
And sealing grooves are respectively arranged on the bottom end surface of the flange cover and the transition short pipe, and O-shaped rings are clamped in the sealing grooves.
The top end of the plugging rod is provided with a section of fixing screw rod, the middle part of the fixing rod is provided with a shaft sleeve matched with the fixing screw rod, the position of the fixing rod on the fixing screw rod is adjustable, and the upper end and the lower end of the fixing rod are fixedly locked through nuts.
The fixed clamping plate is of an E-shaped structure, the bottom end of the fixed clamping plate is fixed on the flange cover, side bayonets of the fixed clamping plate are oppositely arranged on two sides, and a fixed column matched with the fixed mounting hole is arranged on the mounting surface of the bottom end of the fixed clamping plate.
The principle is as follows: the flexible material is put into the pipeline diffusion short pipe below the valve to achieve the plugging effect through expansion (by utilizing the expansion and the generated friction force), so that the valve (gasket) is replaced; this plugging device utilizes three sealings (twice O type circle, one main seal is the polyurethane stick), a transition section pipe, and it is effectual through many times of strong pressure experiment shutoff, installation, shutoff, dismouting, shutoff, will be through twice safety insurance, one shutoff effect inspection.
The utility model has the advantages that:
the utility model has reasonable structure design, and the valve (gasket) can be safely replaced without stopping air, thereby reducing the influence of air stopping on users; economic benefit, and reduced loss of fuel gas emission.
