Description
Technical field
This utility model is related to eccentric half-ball valve technical field, more particularly to a kind of multi-sealed knot of eccentric half-ball valve
Structure.
Background technology
Eccentric half-ball valve is also c-type ball valve, is making valve unimpeded or inaccessible, its light, volume of switch by rotary hemispherical
It is little, very heavy caliber can be made, simple structure is easy to maintenance, and sealing surface, is difficult to be rushed by medium often in closure state with sphere
Erosion, is widely used in the operating mode that oil, chemical industry, urban water supply and sewerage etc. require strict seal.
The eccentric half-ball valve for using at present, according to the difference of sealing surface, can be divided into soft seal eccentric half-ball valve with hard sealing
Eccentric half-ball valve, soft seal typically adopt rubber seal, easily aging, come off, and lose sealability, and hard sealing is general to be adopted
Rustless steel sealing ring, easy seepage, sealing effectiveness are difficult to ensure；In actual applications, the sealing of sealing surface is often only with one
Road is sealed, once seal failure, then can cause valve leak, cause serious consequence.
The content of the invention
This utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of multi-sealing structure of eccentric half-ball valve.
This utility model for achieving the above object, is employed the following technical solutions：A kind of multi-sealed knot of eccentric half-ball valve
Structure, including valve body, valve element and valve seat, in the valve body, the valve seat is rustless steel sealing ring to the valve element, and the valve seat is located at
At the sealing surface of valve body, valve seat pressed spool in valve closing is provided with triangle sealing between the valve seat and valve body
Circle, delta-ring pressed spool in valve closing are provided with tetrafluoroethene sealing ring between the valve seat and valve element,
The tetrafluoroethene sealing ring and valve element plane contact, the valve seat are located at delta-ring and tetrafluoro with the contact surface of valve element
Between ethylene sealing ring, the delta-ring is sealed for first.
Described delta-ring is nitrile rubber sealing ring.
Described valve seat outer round surface is provided with groove, and O-ring seals are provided with groove.
The beneficial effects of the utility model are：This utility model has multi-sealed, first of delta-ring composition
Sealing, valve seat constitute second sealing, and tetrafluoroethene sealing ring constitutes three seals, and delta-ring and tetrafluoro second
Alkene sealing ring is soft seal, and to seal firmly, valve is difficult leakage to valve seat, it is ensured that sealing effectiveness.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- valve seats；2- valve bodies；3-O shape sealing rings；4- delta-rings；5- valve elements；6- tetrafluoroethene is sealed
Circle；
It is described in detail below with reference to embodiment of the present utility model referring to the drawings.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in figure 1, a kind of multi-sealing structure of eccentric half-ball valve, including valve body 2, valve element 5 and valve seat 1, the valve
In the valve body 2, the valve seat 1 is rustless steel sealing ring to core 5, the valve seat 1 at the sealing surface of valve body 2, the valve seat 1
The pressed spool 5 in valve closing, is provided with delta-ring 4, the delta-ring 4 between the valve seat 1 and valve body 2
The pressed spool 5 in valve closing, is provided with tetrafluoroethene sealing ring 6 between the valve seat 1 and valve element 5, the tetrafluoroethene is close
Seal 6 and 5 plane contact of valve element, the valve seat 1 are located at delta-ring 4 and tetrafluoroethene sealing with the contact surface of valve element 5
Between circle 6, the delta-ring 4 is sealed for first.
Described delta-ring 4 is nitrile rubber sealing ring.
Described 1 outer round surface of valve seat is provided with groove, and O-ring seals 3 are provided with groove.
During work, valve element 5 is rotated at the sealing surface of valve body 2,4 pressed spool of delta-ring 5 constitute first it is close
Envelope, 1 pressed spool of valve seat 5 constitute second sealing, and 6 pressed spool of tetrafluoroethene sealing ring 5 constitutes three seals, triangle
Sealing ring 4 and tetrafluoroethene sealing ring 6 are soft seal, and to seal firmly, three seals collective effect, seal form are difficult valve seat 1
Destroyed, valve is difficult leakage.
This utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that this utility model is implemented not to be received
The restriction of aforesaid way, if the various improvement that method design of the present utility model and technical scheme are carried out are employed, or without
Improvement directly applies to other occasions, within protection domain of the present utility model.
