Description
Technical field
This utility model relates to a kind of self sealss eccentric half-ball valve.
Background technology
At present, known eccentric half-ball valve includes valve body, admission chamber it is provided with in valve body, one end of valve body is provided with the inlet opening that connects with admission chamber, the other end is provided with the apopore connected with admission chamber, body top connects valve gap, and valve gap connects main valve axle, and body base is provided with secondary valve shaft, it is provided with the hemispherical valve plate being connected on main valve axle and secondary valve shaft in admission chamber, the surface of hemispherical valve plate is coated with elastic sealing layer.Elastic sealing layer is carried out extruding it is allowed to deformation by coordinating of hemispherical valve plate and inner port position, inlet opening and realizes sealing.The eccentric half-ball valve of said structure, when elastic sealing layer compression is less, easily causes ball valve seepage or leakage.If increase compression, open and close moment of torsion can be caused to increase and the valve plate lost of life.
Utility model content
The technical problems to be solved in the utility model is for drawbacks described above, it is provided that the self sealss eccentric half-ball valve of a kind of good sealing effect.
For solving above-mentioned technical problem, this utility model provides the self sealss eccentric half-ball valve of a kind of following structure, including valve body, admission chamber it is provided with in valve body, one end of valve body is provided with the inlet opening connected with admission chamber, the other end is provided with the apopore connected with admission chamber, body top connects valve gap, connect on valve gap and have main valve axle, body base is provided with secondary valve shaft, the hemispherical valve plate being connected on main valve axle and secondary valve shaft it is provided with in admission chamber, it is coated with elastic sealing layer on the surface of hemispherical valve plate, its construction features is: the elastic sealing layer of described hemispherical sealing surface of valve plate can form the axial seal pair realizing axial seal with the inner port location contacts of inlet opening after coordinating；Elastic sealing layer on described hemispherical sealing surface of valve plate contacts with the hole wall of inlet opening and can form the radial seal pair with radially self sealss effect after coordinating.
Described axial seal pair is formed after directly being contacted with the inner port position of inlet opening by the elastic sealing layer on hemispherical sealing surface of valve plate.
Elastic sealing layer local evagination on described hemispherical sealing surface of valve plate thus form the ring lip can fitted with the hole wall of inlet opening, described radial seal secondary with the described lateral surface of ring lip contacts with the hole wall of inlet opening after formed.
The contour line of the medial surface of described ring lip is obliquely installed relative to the axis of described inlet opening, so that the medial surface of described ring lip becomes taper seat.
The contour line of the lateral surface of described ring lip is obliquely installed for the axis of described inlet opening or be arranged in parallel, so that the lateral surface of described ring lip is the face of cylinder or taper seat.
After elastic sealing layer on the seal face of hemispherical valve plate coordinates with the inner port location contacts of inlet opening, it is secondary that the two can form axial seal, thus realizes axial seal；Elastic sealing layer contacts the latter two with the hole wall of inlet opening can form radial seal pair, thus realizes radial seal.The medial surface of described ring lip being set to taper seat and can bring following benefit: fluid pressure can produce radial component after acting on medial surface, this radial component can make the more tight of the lateral surface of ring lip and the hole wall laminating of inlet opening, forms self sealss.That is this utility model both can realize axial seal by elastic sealing layer, it is possible to realizes radially self sealss by ring lip.
In sum, the utility model has the advantage of: simple in construction that there is axial seal and radial seal double effects, do not easily cause seepage or leakage, open moment of torsion little, the service life of valve can be extended.

Detailed description of the invention
As depicted in figs. 1 and 2, self sealss eccentric half-ball valve includes valve body 1, admission chamber 2 it is provided with in valve body 1, one end of valve body 1 is provided with the inlet opening 3 that connects with admission chamber 2, the other end is provided with the apopore 4 connected with admission chamber 2, valve body 1 top connects valve gap 5, and valve gap 5 connects main valve axle 6, is provided with secondary valve shaft 7 bottom valve body 1, it is provided with the hemispherical valve plate 8 being connected on main valve axle 6 and secondary valve shaft 7 in admission chamber 2, the surface of hemispherical valve plate 8 is coated with elastic sealing layer 9.The described elastic sealing layer 9 of hemispherical valve plate 8 sealing surface can form the axial seal pair realizing axial seal after directly contacting cooperation with the inner port position of inlet opening 3.Elastic sealing layer 9 on described hemispherical valve plate 8 sealing surface contacts with the hole wall of inlet opening 3 and can form the radial seal pair with radially self sealss effect after coordinating.Elastic sealing layer 9 local evagination on described valve plate 8 sealing surface thus form the ring lip 10 can fitted with the hole wall of inlet opening 3, described radial seal secondary with the lateral surface of described ring lip 10 contacts with the hole wall of inlet opening 3 after formed.Described hemispherical valve plate 8 closes main valve axle described in tailing edge 6 axially in the orthographic projection diagram of its cutting i.e. in the situation shown in Fig. 1 and Fig. 2, the contour line 11 of the medial surface of ring lip 10 is obliquely installed relative to the axis of described inlet opening 3, so that the medial surface of described ring lip 10 becomes taper seat.Described hemispherical valve plate 8 closes main valve axle described in tailing edge 6 axially in the orthographic projection diagram of its cutting i.e. in the situation shown in Fig. 1 and Fig. 2, the contour line 12 of the lateral surface of ring lip 10 can be obliquely installed relative to the axis of described inlet opening 3, can also be arranged in parallel, so that the lateral surface of described ring lip 10 is the face of cylinder or taper seat.Fig. 2 showing, the situation that the contour line 12 of the lateral surface of ring lip 10 be arranged in parallel relative to the axis of described inlet opening 3, the i.e. lateral surface of ring lip 10 are the face of cylinder；Fig. 3 shows the situation that the contour line 12 of the lateral surface of ring lip 10 is obliquely installed relative to the axis of described inlet opening 3, the i.e. lateral surface of ring lip 10 is taper seat, depending on the contour line 11 of the medial surface of institute's ring lip 10 can require according to design relative to the angle of inclination that the axis of described inlet opening 3 is obliquely installed.
Above-mentioned radial seal secondary with the lateral surface of described ring lip 10 contacts with the hole wall of inlet opening 3 after formed.The medial surface of described ring lip 10 is set to taper seat and can bring following benefit: after valve closing, fluid pressure can produce radial component after acting on medial surface, this radial component can make the lateral surface of ring lip tightly fit with the hole wall of inlet opening 3, form self sealss, and the biggest radial component of fluid pressure is the biggest, ring lip is the tightest with what the hole wall of inlet opening 3 was fitted.
