Abstract
The utility model discloses a knife switch type air seal valve which comprises a tubular valve body, wherein an annular seat is arranged on the inner wall of the valve body; baffles are respectively mounted on the upper parts of two end ring openings of the annular seat; an airbag is arranged on the inner wall of the top of the annular seat; an air port which is communicated to the airbag is formed in the top of the valve body. The knife switch type air seal valve has the advantages that the service life is long, the sealing property is good, and the turn-off capacity is strong.
Description
Technical field
The utility model relates to valve field, is specially a kind of disconnecting link formula air sealing valve.
Background technique
Knife gate valve claims again cutter door gate valve, has the advantages such as volume is little, flow resistance is little, easy installation, convenient disassembly, is widely used in the pipe-line system of every profession and trade the liquid being used in cutting out pipeline system.Prior art knife gate valve is simple in structure, and between disconnecting link and valve body, rigidity contacts, the problem that lives forever service time and decline in sealing.
Model utility content
The purpose of this utility model is to provide a kind of disconnecting link formula air sealing valve, to solve the prior art knife gate valve problem that service time, long sealing declined.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of disconnecting link formula air sealing valve, include tubular valve body, it is characterized in that: valve interior wall is provided with annular seating, collar extension top, annular seating two ends is separately installed with baffle plate, in described annular seating top inner wall, be provided with the air bag that elastic water-proof rubber is made, and baffle plate blocks balloon ends at annular seating two ends, described valve body top is also provided with gas port, stretch out from valve body on described gas port top, and gas port bottom is communicated to air bag through annular seating.
Described a kind of disconnecting link formula air sealing valve, is characterized in that: described annular seating bottom interior wall is provided with groove.
When the utility model is used, by inflating in air bag, make air bag lower expansion to inserting in groove, thereby collar extension is closed, realize turn-off function.The utility model utilizes airbag aeration to turn-off, and Elastic Contact between air bag and valve body has advantages of length service time, good airproof performance, strong turn-off capacity.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
