FIG. 4 is a schematic sectional view A-A of FIG. 3 according to the present invention.
Detailed Description
As shown in the drawings, the present invention comprises a valve body 1, a valve plate 2 and a pair of cylinders 3,
Be equipped with a pair of flange 7 on valve body 1, the inner chamber upper portion of valve body 1 is uncovered form valve plate moving area, the inner chamber lower part of valve body 1 is closed form valve plate moving area, spout 4 has been opened respectively on the both sides upper portion of valve body 1, valve plate 2 is semi-circular, the top of valve plate 2 is equipped with cylinder pushing plate 5, a pair of draw-in groove 6 has been opened respectively at the both ends of cylinder pushing plate 5, valve plate 2 is located the inner chamber of valve body 1, cylinder pushing plate 5 passes through draw-in groove 6 slidable mounting in spout 4, a pair of cylinder 3 is mirror image distribution and installs on the lateral wall of valve body 1, one of them cylinder 3 and the one end fixed connection of cylinder pushing plate 5, wherein another cylinder 3 and the other end fixed connection.
A pair of symmetrically-distributed circular ring sealing ring mounting grooves are formed in the inner wall of a moving area of a closed valve plate of the valve body 1, inflation sealing rings 8 are arranged in the circular ring sealing ring mounting grooves respectively, a first inflation connector 9, a first deflation connector 10, a second inflation connector 11 and a second deflation connector 12 are arranged on the valve body 1, the first inflation connector 9 and the first deflation connector 10 are communicated with an air inlet and an air outlet of one inflation sealing ring 8 respectively, and the second inflation connector 11 and the second deflation connector 12 are communicated with an air inlet and an air outlet of the other inflation sealing ring 8 respectively.
