Description of reference numerals: 1. the valve comprises a valve leaf, 11 mounting grooves, 12 sealing grooves, 121, a first sealing groove, 122, a second sealing groove, 123, a connecting block, 2, a positioning connecting rod, 3, a connecting piece, 4, a case body, 41, a rotating shaft and 42, a blocking block.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Figures 1 and 2 show the wing check valve of the present invention.
A wing type check valve comprises a plurality of valve blades 1, wherein each valve blade 1 is provided with a mounting groove 11 for mounting a rotating shaft, the upper side and the lower side of each valve blade 1 are respectively provided with a sealing groove 12, an elastic body (not shown) is arranged in each sealing groove 12, and when the valve is closed, the elastic bodies on the upper side and the lower side of each valve blade 1 are respectively abutted to the adjacent valve blades 1.
