Description
Technical field
The present invention relates to a kind of selfsealings eccentric half-ball valve.
Background technique
At present, known eccentric half-ball valve comprises valve body, admission chamber is provided with in valve body, one end of valve body is provided with the water inlet, the other end that are communicated with admission chamber and is provided with the osculum be communicated with admission chamber, body top is connected with valve gap, valve gap is connected with main valve axle, and body base is provided with secondary valve shaft, be provided with the hemispherical valve plate be connected on main valve axle and secondary valve shaft in admission chamber, the surface of hemispherical valve plate is coated with elastic sealing layer.Extruding is carried out to elastic sealing layer make it distortion to realize to seal by coordinating of hemispherical valve plate and inner port position, water inlet.The eccentric half-ball valve of said structure, when elastic sealing layer compressive strain is less, easily causes ball valve seepage or leakage.If increase compressive strain, open and close moment of torsion can be caused to increase and the valve plate lost of life.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned defect, provides a kind of selfsealings eccentric half-ball valve of good sealing effect.
For solving the problems of the technologies described above, the invention provides a kind of selfsealings eccentric half-ball valve of following structure, comprise valve body, admission chamber is provided with in valve body, one end of valve body is provided with the water inlet be communicated with admission chamber, the other end is provided with the osculum be communicated with admission chamber, body top is connected with valve gap, valve gap is connected with main valve axle, body base is provided with secondary valve shaft, the hemispherical valve plate be connected on main valve axle and secondary valve shaft is provided with in admission chamber, the surface of hemispherical valve plate is coated with elastic sealing layer, its structural feature is: the elastic sealing layer of described hemispherical sealing surface of valve plate can form the axial seal realizing axial seal after coordinating with the inner port location contacts of water inlet secondary, elastic sealing layer on described hemispherical sealing surface of valve plate can form the radial seal with radial selfsealings effect after contacting with the hole wall of water inlet and coordinating secondary.
Described axial seal pair directly contacts rear formation by the elastic sealing layer on hemispherical sealing surface of valve plate with the inner port position of water inlet.
Elastic sealing layer local evagination on described hemispherical sealing surface of valve plate thus form the ring lip that can fit with the hole wall of water inlet, described radial seal is secondary to be contacted to coordinate with the hole wall of water inlet by the described outer side surface of ring lip and is formed afterwards.
Described hemispherical valve plate is axial in the orthographic projection diagram of its cutting along described main valve axle after closing, and the profile line of the inner side surface of ring lip is obliquely installed relative to the axis of described water inlet, thus makes the inner side surface of described ring lip become conical surface.
Described hemispherical valve plate close after along described main valve axle axially in the orthographic projection diagram of its cutting, the profile line of the outer side surface of ring lip is obliquely installed for the axis of described water inlet or be arranged in parallel, thus makes the outer side surface of described ring lip be cylndrical surface or conical surface.
After elastic sealing layer on the seal face of hemispherical valve plate coordinates with the inner port location contacts of water inlet, the two can form axial seal pair, thus realizes axial seal; Elastic sealing layer contacts the latter two with the hole wall of water inlet can form radial seal pair, thus realizes radial seal.The inner side surface of described ring lip is set to conical surface and can brings following benefit: fluid pressure action on inner side surface after can produce radial component, it is more tight that this radial component can make the outer side surface of ring lip and the hole wall of water inlet fit, and forms selfsealings.That is the present invention both realized axial seal by elastic sealing layer, also realized radial selfsealings by ring lip.
In sum, the invention has the advantages that: structure is simple, has axial seal and radial seal double effects, not easily causes seepage or leakage, open moment of torsion little, the working life of valve can be extended.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
The structural representation of Fig. 1 selfsealings eccentric half-ball valve cut-off state;
Fig. 2 is the schematic diagram of the enlarged view in A portion in Fig. 1 and a kind of ring lip of structure;
Fig. 3 is the schematic diagram of the enlarged view in A portion in Fig. 1 and the ring lip of another kind of structure.
Embodiment
As depicted in figs. 1 and 2, selfsealings eccentric half-ball valve comprises valve body 1, admission chamber 2 is provided with in valve body 1, one end of valve body 1 is provided with the water inlet 3, the other end that are communicated with admission chamber 2 and is provided with the osculum 4 be communicated with admission chamber 2, valve body 1 top is connected with valve gap 5, valve gap 5 is connected with main valve axle 6, is provided with secondary valve shaft 7 bottom valve body 1, be provided with the hemispherical valve plate 9 be connected on main valve axle 6 and secondary valve shaft 7 in admission chamber 2, the surface of hemispherical valve plate 9 is coated with elastic sealing layer 10.The axial seal realizing axial seal can be formed secondary after the described elastic sealing layer 9 of hemispherical valve plate 9 sealing surface directly contacts cooperation with the inner port position of water inlet 3.Elastic sealing layer 9 on described hemispherical valve plate 9 sealing surface can form the radial seal with radial selfsealings effect after contacting with the hole wall of water inlet 3 and coordinating secondary.Elastic sealing layer 9 local evagination on described valve plate 8 sealing surface thus form the ring lip 10 that can fit with the hole wall of water inlet 3, the secondary outer side surface by described ring lip 10 of described radial seal contacts to coordinate with the hole wall of water inlet 3 and is formed afterwards.Described hemispherical valve plate 9 close after along described main valve axle 6 axially in the orthographic projection diagram of its cutting namely in the situation shown in Fig. 1 and Fig. 2, the profile line 11 of the inner side surface of ring lip 10 is obliquely installed relative to the axis of described water inlet 3, thus makes the inner side surface of described ring lip 10 become conical surface.Described hemispherical valve plate 9 close after along described main valve axle 6 axially in the orthographic projection diagram of its cutting namely in the situation shown in Fig. 1 and Fig. 2, the profile line 12 of the outer side surface of ring lip 10 can be obliquely installed relative to the axis of described water inlet 3, also can be arranged in parallel, thus makes the outer side surface of described ring lip 10 be cylndrical surface or conical surface.The situation that the profile line 12 of the outer side surface of ring lip 10 is arranged relative to the axis being parallel of described water inlet 3 has been shown in Fig. 2, and namely the outer side surface of ring lip 10 is cylndrical surface; The situation that the profile line 12 of the outer side surface of ring lip 10 is obliquely installed relative to the axis of described water inlet 3 has been shown in Fig. 3, namely the outer side surface of ring lip 10 is conical surface, and the angle of inclination that the profile line 11 of the inner side surface of institute's ring lip 10 is obliquely installed relative to the axis of described water inlet 3 can be determined according to designing requirement.
