Abstract
The invention provides an air sealing valve, which comprises a valve body that is provided with a middle cavity consisting of two sets of valve seats, a seal ring, a valve plate and a pressure plate, the seal ring is fixed on the valve plate through the pressure plate, the valve body between the two valve seats is connected with a pipeline, the pipeline is provided with a decompression filter which is connected with compressed air, and the seal ring of the valve is made of fluororubber. The air sealing valve has the beneficial effects of adopting the compressed air as a sealing medium, saving water resources, having low cost, being capable of regulating the pressure of the compressed air and having reliable sealing and safe use.
Description
Affiliated technical field
The present invention relates to a kind of valving, especially a kind of air sealing valve.
Background technique
Use water-sealing valve mostly at the metallurgy industry gas pipe line at present, adopt the bivalve plate structure, the lumen between the bivalve plate injects water and makes sealing medium, and is reliable for guaranteeing sealing, and the pressure of lumen water must be greater than the pressure of valve plate outside coal gas.Its shortcoming is a complicated operation, during unlatching, to put the water of lumen totally earlier, and earlier valve plate is closed will seal the time, lumen fills with water again, opening and closing in addition once needs to consume a large amount of water, if the pressure of water seal is 0.1MPa, then need build 10 meters high water towers, the user cost height, expending of water resources is more serious.
Summary of the invention
For overcoming the deficiency that has the water-sealing valve complicated operation now, expends great lot of water resources, the invention provides a kind of air sealing valve.
The technological scheme that its technical problem of solution of the present invention adopts is a kind of air sealing valve, comprise valve body, the lumen of forming by two cover valve seats, seal ring, valve plate, pressing plate on the valve body, seal ring is fixed on the valve plate by pressing plate, on the valve body in the middle of two valve seats, be connected to pipeline, vacuum filter is housed on the pipeline, connects pressurized air.
The seal ring material of valve adopts fluorine rubber.
Beneficial effect of the present invention adopts pressurized air as sealing medium, has saved water resources, and cost is low, and compressed-air actuated in addition pressure can be regulated, and sealing is reliable, and is safe in utilization.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is embodiment's a sectional structural map;
Among the figure: 1. valve body; 2. valve seat; 3. seal ring; 4. pipeline; 5. pressing plate; 6. vacuum filter; 7. valve plate.
Embodiment
As shown in Figure 1, a kind of air sealing valve, comprise valve body 1, the lumen of forming by two cover valve seats 2, seal ring 3, valve plate 7, pressing plate 5 on the valve body 2, seal ring 3 is fixed on the valve plate 7 by pressing plate 5, on the valve body 1 in the middle of two valve seats 2, be connected to pipeline 4, vacuum filter 6 is housed on the pipeline 4, connect pressurized air.For adapting to the coal gas of high temperature medium, seal ring 3 materials of valve can adopt fluorine rubber.Regulate compressed-air actuated pressure by regulating vacuum filter 6, maintain setting value with guaranteeing compressed-air actuated pressure stability, sealing is reliable.
Claims (2)
1. an air sealing valve comprises valve body, the lumen of being made up of two cover valve seats, seal ring, valve plate, pressing plate on the valve body, seal ring is fixed on the valve plate by pressing plate, on the valve body in the middle of two valve seats, be connected to pipeline, it is characterized in that: vacuum filter is housed on the pipeline, connects pressurized air.
2. air sealing valve according to claim 1 is characterized in that: described seal ring is a fluorine rubber.
