Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of technical solution referring to FIG. 1-2: a kind of valve seat of flow adjustable cut-off valve, including valve body
1, the center of valve body 1 laterally offers discharge orifice 2, facilitates circulation water, and the center of discharge orifice 2 is equipped with valve ball 3, the top of valve ball 3
Valve rod 4 is installed, the center of top of valve body 1 is installed valve rod fixing piece 5 by bolt, offered at left and right sides of the inner wall of valve body 1
Annular groove 6, two groups of annular grooves 6 are respectively mounted gasket 7, the two groups of sides of annular groove 6 far from gasket 7 close to the side of valve rod 4
It is respectively mounted fixed block 8, fixed block 8 is provided with movable block 9 close to a Slideslip of gasket 7, on fixed block 8 and movable block 9
Through-hole 10 is offered, threaded hole 11 is offered at left and right sides of 1 upper top of valve body and bottom, is plugged with screw rod in threaded hole 11
