Abstract
The utility model discloses a kind of corrosion-resistant fixing ball valves, including valve body, sphere and valve seat, the sphere, valve seat are all set in valve body, and sphere and valve seat form sealing cooperation, there is the valve port for medium disengaging, the valve seat opens up fluted on the outer ring at valve port, is sealed and installed with y-type seal ring on the groove on the valve body, the lateral wall of the y-type seal ring is resisted against on valve interior wall, and the material of y-type seal ring is polytetrafluoroethylene (PTFE).Y-type seal ring is put by script expansion shape compression to groove, is formed to elastic packing is carried out at sealing, and the material of polytetrafluoroethylene (PTFE) is corrosion-resistant, can integrally seal up the gap between valve seat and valve body for a long time, and structure is simple, and sealing is persistently effective.
Description
Technical field
The utility model relates to ball valve field, specifically corrosion-resistant fixing ball valve.
Background technique
Fixing ball valve is suitable for long-distance transport pipes and general industry pipeline, and intensity, safety, adverse environment resistant etc. are being set
Timing has carried out special consideration, is suitable for various corrosivity and non-aggressive medium.But in corrosive medium, in valve seat
O-ring seal is since usually by the material production of fluorubber moreover, its corrosion resistance is poor, some O-ring seals use corrosion resistant
The polytetrafluoroethylene material of erosion, but polytetrafluoroethylene material elastic property itself is poor, can not form effective sealing.
Summary of the invention
The purpose of this utility model: in order to overcome the drawbacks of the prior art, the utility model provides a kind of corrosion-resistant solid
Determine ball valve.
The technical solution of the utility model includes: including valve body, sphere and valve seat, the sphere, valve seat are all set in valve body
It is interior, and sphere and valve seat form sealing cooperation, have the valve port for medium disengaging on the valve body, the valve seat is close to valve
It opens up fluted on outer ring at mouthful, y-type seal ring is sealed and installed on the groove, the lateral wall of the y-type seal ring supports
It leans against on valve interior wall, the material of y-type seal ring is polytetrafluoroethylene (PTFE).
By adopting the above technical scheme, y-type seal ring being put into groove by script expansion shape compression is formed to sealing
Elastic packing is carried out, the material of polytetrafluoroethylene (PTFE) is corrosion-resistant, the gap between valve seat and valve body can be integrally sealed up for a long time,
Structure is simple, and sealing is persistently effective.
The further setting of the utility model: y-type seal ring has opening, described to be open towards valve port direction.
Using above-mentioned further setting, it is capable of forming significantly more efficient sealing.
The further setting of the utility model: it is installed against pressing ring, the pressing ring sliding is equipped with the side of opening
Between groove and valve interior wall；The pressing ring side is provided with the convex shoulder extended by valve interior wall, the radial direction of the convex shoulder
There is the channel flowed out for medium, the surface of the pressing ring side is resisted against on convex shoulder, another part on the inside of direction
Expose on a passage side.
Further it is arranged using above-mentioned, medium flow pass applies pressure on pressing ring, and pressing ring is to y-type seal ring opening
Press, y-type seal ring has flared trend, and pressure medium compensates leakproofness, further enhances sealing effect
Fruit.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model specific embodiment；
Fig. 2 is partial enlarged view at A in the utility model Fig. 1；
Fig. 3 is the structural schematic diagram of the utility model y-type seal ring；
Wherein, valve body 1, sphere 2, valve seat 3, valve port 11, y-type seal ring 4, opening 41, pressing ring 5, convex shoulder 12, channel 6.
Specific embodiment
Corrosion-resistant fixing ball valve as shown in FIG. 1 to FIG. 3, including valve body 1, sphere 2 and valve seat 3, sphere 1, valve seat 3 are equal
It is set in valve body 1, and sphere 2 and valve seat 3 form sealing cooperation, have the valve port 11 for medium disengaging, valve on valve body 1
Seat 3 opens up fluted on the outer ring at valve port 11, and y-type seal ring 4, the outside of y-type seal ring 4 are sealed and installed on groove
Wall is resisted against on 1 inner wall of valve body so that y-type seal ring 4 is sealed in the gap between valve body 1 and valve seat 3, y-type seal ring 4 by
The material of polytetrafluoroethylene (PTFE) is made.Y-type seal ring 4 is expansion shape in a pre-installation, when being installed on groove, to 3 He of valve seat
Valve body 1 is squeezed respectively, thus on the gap being sealed between valve body 1 and valve seat 3.
Y-type seal ring 4 has opening 41, and opening 41 is towards 11 direction of valve port；The side being open at 41 is against being equipped with pressure
Circle 5, the sliding of pressing ring 5 are installed between 1 inner wall of groove and valve body；5 side of pressing ring is provided with the convex shoulder extended by 1 inner wall of valve body
12, the radial direction inside of convex shoulder 12 has the channel 6 flowed out for medium, and the surface of 5 side of pressing ring is resisted against convex shoulder 12
On, the side of another part is exposed on channel 6.When medium flows into valve port 11, a part of medium will also flow into channel 6,
Pressure medium is pressed on the side of part pressing ring 5 by channel 6, and the sliding of pressing ring 5 is pressed toward opening 41, the Y type sealing of y-type seal ring 4
Circle 4 has flared trend, and y-type seal ring 4 and 1 inner wall of valve body, valve seat 3 are even closer.Pressing ring 5 had both been able to maintain to Y type
Sealing ring 4 presses, and can reinforce pressing to y-type seal ring 4 by pressure medium, is applicable under high-pressure medium environment.
