Abstract
The present invention is a kind of equilibrant force bellows stop valve, including valve body 1, flap 2, valve rod 3, the flap 2 is connected with the valve rod 3, it is characterized in that, the inner cavity that the flap 2 is spaced the valve body 1 is cavity of resorption 4, epicoele 5, the flap 2 offers through hole 6, and 6 upper end of through hole connects the epicoele 5, and 6 lower end of through hole connects the cavity of resorption 4.The application greatly reduces the closing forces of valve, can be reduced with the diameter of this valve rod, reduces opposite frictional resistance so that the closing of valve is lighter.
Description
Technical field
The present invention relates to valve industry, and in particular to a kind of equilibrant force bellows stop valve.
Background technology
The closing forces of stop valve clack originally are big.The reason is that the pressure of liquid is excessive, during flap closes
Need to overcome larger liquid pressure to close, it is therefore desirable to seek a kind of technical solution to solve above-mentioned technical problem.
The content of the invention
The present invention provides equilibrant force bellows stop valve, designs and develops the purpose of this product, greatly reduces valve
Closing forces, can be reduced with the diameter of this valve rod, reduce opposite frictional resistance so that the closing of valve is lighter.
The present invention provides following technical proposals：Equilibrant force bellows stop valve, including valve body 1, flap 2, valve rod 3, institute
Flap 2 to be stated to be connected with the valve rod 3, it is characterised in that the inner cavity that the flap 2 is spaced the valve body 1 is cavity of resorption 4, epicoele 5,
The flap 2 offers through hole 6, and 6 upper end of through hole connects the epicoele 5, and 6 lower end of through hole connects the cavity of resorption 4.
The flap 2 is flexibly connected with the valve rod 3 by bearing 7, and the bearing 7 is crimped by bearing (ball) cover 8.Positioning
Set 12 is fixedly connected with the valve body, and the valve deck 10, valve body 1 crimp the positioning sleeve 12, the flap and the positioning sleeve
12 are flexibly connected.
The valve rod 3 is screwed on 1 screw thread of valve body.
Beneficial effects of the present invention.1st, the closing forces of original stop valve clack are big, the pass of amended stop valve clack
Power is closed as the big thrust of stem diameter area；2nd, present flap is sealed by O-ring seal, and O-shaped rubber seal has good
Leakproofness, it is a kind of compressed line sealing ring, while has self-styled ability, so use scope is very wide, seal pressure is
1.33X10-5pa to the high pressure of 400Mpa（Dynamic sealing is up to 35Mpa）.If material selection is appropriate, temperature range for -60~
200°C.O-ring structure is simple, and old cheap, easy to use, therefore leakproofness, obtains extensively from the influence of the direction of motion
Application；3rd, the practicality of this structure and Special stop valve for chlorine gas, common shut-off valve, bellows stop valve, and other Direct Travels
It is conical valve to cut sealing surface.4th, this structure greatly reduces the closing forces of valve, can be reduced with the diameter of this valve rod,
Reduce opposite frictional resistance so that the closing of valve is lighter.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
Below in conjunction with attached drawing, the invention will be further described with specific embodiment.
In Fig. 1：Valve body 1, flap 2, valve rod 3, cavity of resorption 4, epicoele 5, through hole 6, bearing 7, bearing (ball) cover 8, bellows 9, valve
Lid 10, flange gasket 11, positioning sleeve 12, O-ring seals 13, filler 14.
Equilibrant force bellows stop valve, including valve body 1, flap 2, valve rod 3, the flap 2 are connected with the valve rod 3, institute
State flap 2 and be spaced the inner cavity of the valve body 1 as cavity of resorption 4, epicoele 5, the flap 2 offers through hole 6, and 6 upper end of through hole connects
Lead to the epicoele 5,6 lower end of through hole connects the cavity of resorption 4.What the cavity of resorption 4 imported is high pressure liquid, as shown in the figure cavity of resorption
5 pressure is excessive, causes flap 2 to need to overcome larger pressure to close with valve body 1, so as to cause this valve very difficulty
Close.Originally the high pressure that through hole 6 has shed liquid has been opened up, the closing forces of present apparatus stop valve clack push away for stem diameter area is big
Power, causes this valve to close laborsaving convenience.
The flap 2 is flexibly connected with the valve rod 3 by bearing 7, and the bearing 7 is crimped by bearing (ball) cover 8.It is described
Valve rod 3 is screwed on 1 screw thread of valve body.
Bellows 9, valve deck 10, flange gasket 11, positioning sleeve 12, O-ring seals 13, filler 14 as shown in the figure.And valve
The essential element of door, bellows 9 are used for valve stem seal, and valve deck 10 completes the assembling of valve, and flange gasket 11 is assembled as a kind of
Indispensable parts, positioning sleeve 12 is fixedly connected with the valve body, and the valve deck 10, valve body 1 crimp the positioning sleeve 12, described
Flap is flexibly connected with the positioning sleeve 12.
