Limitation.
Referring to figs. 1 to known to Fig. 4: a kind of novel short flat gate valve, including gate valve assembly 1, valve body 2, valve seat 3, sealing
Circle 4, spring 5, positioning sleeve 6 and flashboard 7,1 bottom end of gate valve assembly are fixedly connected with valve body 2, in the 2 lower section through-hole of valve body
Left and right sides central symmetry is movably installed with valve seat 3 respectively, is movably installed with flashboard 7, the flashboard between two valve seats 3
7 upper ends are threadedly attached on the valve rod on gate valve assembly 1, and sealing is equipped between the outer ring and valve body 2 of two valve seats 3
Circle 4 is sealed, and sealing ring 4 is equipped between the side elevation and flashboard 7 of two valve seats 3 and is sealed, two valve seats 3
Multiple springs 5 are uniformly installed respectively around central axes between another side elevation and valve body 2, multiple springs 5 push up valve seat 3
Tightly on flashboard 7, groove 301, the left and right two of the 2 lower section through-hole of valve body are respectively equipped on the inner hole wall of two valve seats 3
End has been respectively fixedly connected with positioning sleeve 6, and limiting stand 601, the limiting stand are integrally formed on the inner end outer ring of the positioning sleeve 6
601 are arranged in groove 301.
The valve seat 3 is slidably matched with valve body 2, and the valve seat 3 is slidably matched with positioning sleeve 6, can be in valve convenient for valve seat 3
It is moved in body 2；The sealing ring 4 is " O " type sealing ring, is easy to use；The positioning sleeve 6 is divided into muti-piece, determines described in muti-piece
Position set 6 is respectively fixedly connected in the through-hole of valve seat 3 and valve body 2, and the outer end of muti-piece positioning sleeve 6 is welded and fixed with valve body 2,
