Description
Technical field
This utility model belongs to valve seal technical field, particularly to rubber seal productses and using this rubber seal system
The ball valve of product.
Background technology
Gradually it is widely popularized at the industrial and civilian aspect of China with this clean energy resource of natural gas and popularized, oil sky
So gas industry obtains sustained and rapid development, and digging and pipe network conveying engineering become the important step in construction, and wherein control Jie
Matter is passed through and the valve of blocking effect uses in a large number, especially the large scale high-pressure ball valve quality in long distance line conveying and its
Stability is particularly important.The primary seal of ball valve refers to the sealing between spheroid and valve body, and this sealing is mainly by seal valve seat
To realize.Common ball seat all using plastic material, such as mould by polytetrafluoroethylplastic plastic (PTFE), enhanced polytetrafluoroethylene
Material (RPTFE), nylon (NYLON), polyether-ether-ketone (PEEK) and polyimides (PI) etc., but such material valve seat is using process
Middle generally existing resilience is poor, the problems such as valve torque is big.In order to improve these problems further, ball valve design person are by plastics
Material, metal material, as bracing ring, the excellent elasticity of bound rubber material, form under compressive deformation and effectively seal.China is real
With new patent (publication number：CN202402690) disclose a kind of triangle sealing device of ball valve, it include seal receptacle,
Bracing ring and pressure ring, wherein bracing ring and spheroid sphere directly contact, define first metallic sealing section, elastomeric material close
Envelope seat is contacted with spheroid and defines auxiliary seal.Chinese utility model patent (publication number：CN203335917) disclose liner solid
Fixed pattern triangle circle compound seal valve seat ball valve, its valve base sealing seals the compound of added with triangle rubber sealing for plastic seat
Seal Design, the first order seals to be realized between metal by the plastics of plastic seat and spheroid, and the second level seals by elastomeric material
Delta-ring spheroid is realized seal, play zero leakage.Chinese utility model patent (publication number：
CN204420181) disclose a kind of floating soft sealing ball valve triangle circle valve base mechanism, including triangle circle valve seat groove, triangle circle valve
Seat and parallel bracing ring.Above-mentioned Chinese utility model patent all employs the similar isosceles triangle rubber seal knot of rule
Structure, but this ring structure is under the effect of being stressed, larger with spheroid contact position apex sealing surface stress, easily
Deformation forms sealing surface, but triangle bottom end seal facial plane area is excessive, and under extruding with top stress identical, bottom is close
Front cover stress is less, is difficult to produce efficient deformation formation sealing, in turn results in sealing effectiveness difference and wild effect.Additionally, three
Sometimes stress is excessive on angular sealing ring top, is difficult to for deformation and pressure to pass to bottom, in ball body of valve twist process, friction
Power, moment of torsion are excessive, and apex sealing surface is easy to shear property model.
Utility model content
The purpose of this utility model is for the above-mentioned problems in the prior art, there is provided the more preferable rubber of sealing effectiveness
Glue sealing articles and use its ball valve.
A purpose of the present utility model is to provide a kind of rubber seal productses, and it includes at least one sealing surface, often
At least one recessed, raised or its combination is had on one sealing surface.
Another purpose of the present utility model is to provide a kind of ball valve, and it includes above-mentioned rubber seal productses
Compared with prior art, the utility model has the advantage of：This utility model is by the sealing surface of rubber seal productses
By plane be changed to one, two or more raised or one, the sealing surface of two or more concave groove is so that rubber seal system
When product contact pressurized deformation with spheroid, pressure is easy to be delivered to sealing surface, and the projection on sealing surface or recess are easy to
Stress simultaneously forms effectively one, twice or multiple-sealed face；Additionally, when the top stress of rubber seal productses is excessive, rubber
Sealing articles can tie up bottom groove clearance spaces with deformation, reduces top bossing, and then avoids ball body of valve reversing
During end sealing face shear property model it is ensured that the sealing effectiveness of rubber seal productses.

Specific embodiment
Below by way of several illustrative specific embodiments of the present utility model and combine accompanying drawing, to of the present utility model
Technical scheme is further described, but this utility model is not limited to these embodiments.
In one preferred embodiment, rubber seal productses of the present utility model include rubber seal or rubber is close
Strip of paper used for sealing, preferably rubber seal.
In a preferred embodiment, the cross section of rubber seal productses of the present utility model include triangle,
Positive aspect, rectangle, trapezoidal, semicircle, half elliptic.Preferably triangle includes right angled triangle, equilateral triangle or waits
Lumbar triangle shape.
In a preferred embodiment, rubber seal productses of the present utility model include at least one sealing surface,
Described sealing surface includes plane or arc surface.
In a preferred embodiment, the described recessed inclusion in this utility model rubber seal productses is semicircle
Recessed, ellipse is recessed, triangle is recessed, rectangle is recessed or trapezoidal recessed.
In a preferred embodiment, the raised inclusion described in this utility model rubber seal productses is semicircle
Projection, elliptical shaped lobes, triangular hill, rectangle projection or trapezoidal projection.
In a more preferred embodiment, each sealing surface has one or two recessed or raised.
In a more preferred embodiment, each sealing surface has two or three recessed or raised.
Fig. 1 and Fig. 2 schematically depict a kind of structure chart of the ball valve using this utility model rubber seal.This ball
