Abstract
The utility model relates to a slot connection butterfly valve that is used for linear sealing sphere line with rubber valve plate, including valve body, setting valve shaft, the valve plate of setting between valve body and valve shaft in the valve body, the upper portion and the transmission of valve body are connected, the detachable machinery of valve plate is installed in the valve body and between the valve shaft, the sealed face of valve plate and valve body all is the line contact sphere and seals the face, and sealed of valve plate and seal face of the valve body line contact sphere interference fit formation valve sealing the medium. The beneficial effects of the utility model are that: because the sealed face of valve plate the outer rubber and seal face of the valve body be line contact sphere interference fit, this kind of cooperation form make the product open and close the in -process any angle all to medium sealed formed at the external world, form the sealed even unanimity of each position interference, just reduced the friction with seal face of the valve body. Consequently this design has improved the sealed pressure resistance of product, has reduced the product by a wide margin and has opened and close the moment of torsion, has prolonged the life of product.
Description
Technical field
The invention belongs to valve technology field, particularly relate to a kind of groove for linear sealing sphere line with rubber valve plate
Connect butterfly valve.
Background technology
Groove butterfly valve is to install in pipeline medium application valve, dismantle a kind of product simple, rapid, and it is used
Amount is increasingly extensive, but conventional the type product in terms of valve body, sealing surface of valve plate cooperation because of the design magnitude of interference
Uneven, contact surface is big, causes valve plate rubber during valve opening and closing tight with valve body sealing surface local friction
Weight, valve plate rubber produces aging and damaged in the short time, thus causes product short for service life, open and close torque
Greatly, sealing and pressure aspect to medium are the most not ideal enough.
Because above-mentioned defect, the design people, the most in addition research and innovation, a kind of for line to founding
The groove sealing sphere line with rubber valve plate connects butterfly valve so that it is have more the value in industry.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of service life long, open and close torque is little,
The sealing property of medium and the groove for linear sealing sphere line with rubber valve plate of good pressure-resistant performance are connected butterfly valve.
The groove for linear sealing sphere line with rubber valve plate of the present invention connects butterfly valve, including valve body, is arranged on valve
Internal valve shaft, the valve plate being arranged between valve body and valve shaft, the top of described valve body is connected with transmission device,
Described valve plate is detachable be mechanically mounted on valve body in and valve shaft between, the sealing surface of described valve plate and valve body is all
For linear contact lay spherical seal surface, and sealing surface of valve plate forms valve with valve seal brought into linear contact sphere interference fit
The door sealing to medium.
Further, described sealing surface of valve plate and valve body sealing surface become same axle center spheroid.
Further, described valve plate surface is vulcanized rubber.
Further, being provided with valve body axis hole in described valve body, described valve shaft is arranged in this valve body axis hole,
It is provided with multiple axle sleeve between described valve body axis hole and valve shaft, between adjacent said two axle sleeve, is provided with O shape
Rubber seal.
Further, the number of described axle sleeve is four.
Compared with prior art, the present invention at least have the advantage that due to valve plate outer layer rubber sealing surface with
Valve body sealing surface is linear contact lay sphere interference fit, and this fit form makes product any in opening-closing process
Angle is all formed at the sealing in the external world to medium, forms each position interference uniformity sealed, and reduces
Friction with valve body sealing surface.Therefore the design improves the pressure performance of sealing of product, significantly reduces product
Product open and close torque, extends the service life of product.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technology of the present invention
Means, and can being practiced according to the content of specification, below with presently preferred embodiments of the present invention and coordinate attached
After figure describes in detail such as.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation that in Fig. 1, between valve body and valve plate, linear contact lay ball face sealing is secondary；
Fig. 3 is the structure for amplifying schematic diagram in A portion in Fig. 2.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.With
Lower embodiment is used for illustrating the present invention, but is not limited to the scope of the present invention.
See Fig. 1-3, a kind of ditch for linear sealing sphere line with rubber valve plate described in a preferred embodiment of the present invention
Groove connects butterfly valve, the valve shaft 2 including valve body 1, being arranged in valve body 1, be arranged on valve body 1 and valve shaft 2 it
Between valve plate 3, the top of described valve body 1 is connected with transmission device, the described detachable mechanical erection of valve plate 3
In valve body 1 and between valve shaft 2, described valve plate 3 is all linear contact lay spherical sealed with the sealing surface of valve body 1
Face, and valve plate 3 sealing surface and valve body 1 sealing surface linear contact lay sphere interference fit form close to medium of valve
Envelope.Described valve plate 3 surface is vulcanized rubber.After assembling, valve plate 3 sealing surface and valve body 1 sealing surface become same
One axle center spheroid, valve plate 3 sealing surface and valve body 1 sealing surface linear contact lay sphere interference fit form valve to Jie
The sealing of matter.Fit form makes product in any angle, medium all be formed at the close of the external world in opening-closing process
Envelope, forms each position interference uniformity sealed, and reduces open and close torque.
Being provided with valve body axis hole 11 in described valve body 1, described valve shaft 2 is arranged in this valve body axis hole 11, institute
State and between valve body axis hole 11 and valve shaft 2, be provided with two axle sleeves 4, arrange between adjacent said two axle sleeve 4
There is O shape rubber seal 5.O shape rubber seal 5 and valve shaft 2 form the sealing to medium.
The above is only the preferred embodiment of the present invention, is not limited to the present invention, it is noted that right
For those skilled in the art, on the premise of without departing from the technology of the present invention principle, also may be used
To make some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
