Abstract
The utility model discloses a kind of Y type lip shape valve sealing structures of valve field, including valve body, further include the valve rod that valve body center is arranged in；The valve stem end center is fixedly connected with center-pole, and upper cover plate, fixed block, lower cover plate are successively cased on the center-pole, and the lower cover plate is fixedly connected by nut with center-pole, and the fixed block is cross；Closure forms two grooves up and down between the fixed block and upper cover plate, lower cover plate, is provided with Y type lip-type packing in the groove.The utility model structure is simple, and leakproofness is strong.
Description
Technical field
The utility model relates to valve seal field, in particular to a kind of Y type lip shape valve sealing structure.
Background technique
Valve seal generally uses O-ring, O-ring year it is cheap but also have many shortcomings, as starting friction hinders
Power is big, easily causes to slide suddenly viscous creeping phenomenon suddenly, and when improper use, and O-ring is easily squeezed and turned round, fracture, so as to cause valve
Leakage.
Utility model content
It is simple that the purpose of the utility model is to provide structures, a kind of strong Y type lip shape valve sealing structure of leakproofness.
Purpose of the utility model is realized as follows: a kind of Y type lip shape valve sealing structure, including valve body, further include
The valve rod at valve body center is set；
The valve stem end center is fixedly connected with center-pole, be successively cased on the center-pole upper cover plate, fixed block, under
Cover board, the lower cover plate are fixedly connected by nut with center-pole, and the fixed block is cross；The fixed block and upper cover
Closure forms two grooves up and down between plate, lower cover plate, is provided with Y type lip-type packing in the groove.
Compared with prior art, the utility model have the beneficial effect that due to use the lip-type packing of Y type so that
The expansion of sealing ring stress contacts even closer with valve interior wall in the process of running.
As a preferred embodiment of the present invention, the length of the fixed block length and upper cover plate, lower cover plate is identical.
As the further preferred scheme of the utility model, the height of the Y type lip-type packing is identical as groove height.
As the further preferred scheme of the utility model, the Y type lip-type packing and valve body are in close contact.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 valve body, 2 valve rods, 3 center-poles, 4 upper cover plates, 5 fixed blocks, 6 lower cover plates, 7 nuts, 8 grooves, 9Y type lip shape
Sealing ring.
Specific embodiment
As shown in Figure 1, a kind of Y type lip shape valve sealing structure, including valve body 1, it further include the valve that 1 center of valve body is set
Bar 2；
2 distal center of valve rod is fixedly connected with center-pole 3, and upper cover plate 4, fixed block 5, lower cover are successively cased on center-pole 3
Plate 6, the lower cover plate 6 are fixedly connected by nut 7 with center-pole 3, and fixed block 5 is cross；Fixed block 5 and upper cover plate 4, under
Closure forms two grooves 8 up and down between cover board 6, is provided with Y type lip-type packing 9 in groove 8.
Above-mentioned 5 length of fixed block and upper cover plate 4, the length of lower cover plate 6 are identical.
The height of above-mentioned Y type lip-type packing 9 is identical as 8 height of groove.
Above-mentioned Y type lip-type packing 9 is in close contact with valve body 1.
The working principle of the utility model is described below: 2 stress of valve rod moves downward, and the lip-type packing 9 of Y type is by axial force
It is expanded outward with Fluid pressure, when sealed medium pressure increases, lip is softened, even closer to be bonded with valve body 1.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed by the utility model, this
For the technical staff in field according to disclosed technology contents, not needing creative labor can be special to some of which technology
Sign makes some replacements and deformation, these replacements and deformation are within the protection scope of the present utility model.
