Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be understood by those skilled in the art with feature, to make apparent specific boundary to the protection scope of the utility model
It is fixed.
Embodiment 1
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of work seal collocation structure, including dish plate
Spherical seal surface 1, main dish plate 2, pressing ring 3, rubber seal 4, adjusting screw 5, valve seat 6, pendant collet 7, valve body 8 and holding screw
9, valve body 8 is equipped with main dish plate 2, and the top of main dish plate 2 is equipped with rubber seal 4, and the side of main dish plate 2 is equipped with pressing ring 3, pressing ring
3 are equipped with several holding screws 9, and the top of rubber seal 4 is equipped with valve seat 6, and the bottom end of valve seat 6 is equipped with dish plate spherical sealed
Face 1, the side of valve seat 6 are equipped with pendant collet 7, and pressing ring 3 is equipped with adjusting screw 5.
Rubber ring 4 and pressing ring 3 are fixed on main butterfly plate 2 by adjusting screw 5.
Dish plate spherical seal surface 1 is spherical surface, and rubber seal 4 is built on main dish plate 2, and valve seat 6 passes through rubber seal 4
It is connected with dish plate spherical seal surface 1 with main dish plate 2.
The adjustment gap of rubber seal 4 is 5.8-6.2mm.
Valve seat 6 forms an assembly by the adjusting screw 5 in pendant collet 7, is fixedly linked with the card slot on valve body 8,
Main dish plate 2, rubber seal 4 and pressing ring 3 are combined into a component parts and form sealing element with valve seat 6.
Working principle: a kind of work seal collocation structure, including dish plate spherical seal surface 1, main dish plate 2, pressing ring 3, rubber
Sealing ring 4, adjusting screw 5, valve seat 6, pendant collet 7, valve body 8 and holding screw 9, previous structure, pressing ring 3 and main butterfly plate 2
The problem of gap is small, increases this gap now, this gap is made to play adjustment 4 compression-expansion of rubber seal, meanwhile,
