Working principle of the present invention:
Referring to Figure of description 1-6, in using the present invention, sphere 4 is under pressure to side movement, and the movement of sphere 4 pushes away
The sealing ring 7 of side is mobile on 1 inner wall of moving valve, and presses with sealing ring 7, improves leakproofness, at the same time, sphere 4
Push the turntable 20 of its bottom end mobile, turntable 20 is mobile to push movable block 17 mobile, and the movement of movable block 17 changes loose slot 15
Gas in loose slot 15 is passed into air bag 11, so that being able to maintain in air bag 11 by capacity by 13 part of common air chamber
Relatively large number of gas, so that sealing ring 7 can be close to 4 surface of sphere, then sealing ring 7 is mobile pushes elasticity even
8 compressive deformation of curved bar is connect, while sealing ring 7, also to the coupled pressure pressure of air bag 11, air bag 11 deforms after being pressurized, from
And the gas inside air bag 11 is passed through to the connector 12 being connected and is squeezed out outward, it is communicated with common air chamber 13 on connector 12,
Portion gas is passed into vent branch 22 by common air chamber 13, then is passed into air cavity 23 by vent branch 22, then from air cavity
23 are punched into the air bag 11 of the other side, and the air bag 11 of the other side expands after inflating, and air bag 11 expands against the sealing of its end
The sealing ring 7 not being pressurized, is tightly attached to the other side of sphere 4, so that between 1 inner wall of sphere 4 and valve body always by 7 movement of circle
High leakproofness is kept, is equipped with snap ring 21 at the top and bottom of turntable 20, snap ring 21 can guarantee that turntable 20 can be in movable block 17
Stability will not be improved, by the way that seal assembly 6 is arranged, sphere 4 is pressurized to one from wherein deviating from while movable in upper turn trough 19
The sealing ring 7 of side presses, while driving the turntable 20 of 4 bottom end of sphere mobile, and the gas in loose slot 15 is squeezed in the movement of turntable 20
Out, the mobile gas by air bag 11 of sealing ring 7 squeezes out, and the gas of extrusion enters the air bag 11 of the other side by air cavity 23
In, to push the sealing ring 7 of the other side to sphere 4 surface, integrally make leakproofness of the invention higher；
Airtight and watertight padding is added into the gap between valve rod 5 and valve body 1 in using the present invention referring to Figure of description 7
27, then flexible fastening ring 28 is covered at the top of the gap for having been added to airtight and watertight padding 27, reusing fixing bolt 29 will be elastic
Fixed ring 28 is fixed on 1 top surface of valve body, is equipped with elastic compression ring 30,30 energy of elastic compression ring in 28 bottom of flexible fastening ring
Enough so that airtight and watertight padding 27 is even closer, leakproofness is further increased；
Referring to Figure of description 1, in using the present invention, 1 both ends of valve body are respectively equipped with connecting flange 31, can pass through bolt
Or other fixing pieces are inserted into connecting hole 32, so that installation be fixed to valve body 1 by connecting flange 31, are improved using just
Victory.
