Dismountable connecting head that is provided with respectively on described A channel, B passage, C-channel, in order to connecting tube;
On described connecting head, be also provided with and accept body, described in accept that body extends internally until contact with described smart ball; Be provided with the first seal ring described accepting on body, in described valve body, the opposite end of C-channel is also equipped with the second seal ring, three described the first seal rings and the second seal ring are fixed on described smart ball in valve body.
As preferred technological scheme, described connecting head is provided with internal thread, on described A channel, B passage, C-channel, is respectively equipped with the outside thread matching with described internal thread, and described connecting head is connected with described A channel, B passage, C-channel screw-thread fit.
As preferred technological scheme, described connecting head is provided with outside thread, on described A channel, B passage, C-channel, is respectively equipped with the internal thread matching with described outside thread, and described connecting head is connected with described A channel, B passage, C-channel screw-thread fit.
As preferred technological scheme, on described connecting head, be also provided with fastener, so that connecting tube.
As preferred technological scheme, be also provided with limit assembly in the outside of described A channel, B passage, C-channel, in order to ensure that described connecting head is completely fixed and is connected with valve body.
Beneficial effect:
(1) due to valve body and smart ball employing PVC material, under high temperature condition, there will not be smart ball and valve body card to realize and resemble; Because seal ring is arranged on connecting head, smart ball is suspended in valve body completely to flexible operation simultaneously;
(2) because connecting head and valve body adopt removable Placement, can be to realize easily dismounting and change Sealing, and then reduce water leakage phenomenon;
(3) by the setting of fastener, easy to connect, applied widely.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model: a kind of structural representation of threeway ball valve made of plastic;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1-2, a kind of threeway ball valve made of plastic, comprise valve body 1, handle, smart ball 2, club and Sealing, wherein, valve body 1 is provided with A channel 11, B passage 12 and C-channel 13, in the same horizontal line, the shaft axis of the shaft axis of C-channel 13 and A channel 11, B passage 12 is perpendicular for the shaft axis of A channel 11, B passage 12; Essence ball 2 is provided with D passage 21, E passage 22 and F passage 23, the shaft axis of D passage 21, E passage 22 in the same horizontal line, and distribution and A channel 11, B passage 12 are in the same way concentric, and the shaft axis of the shaft axis of F passage 23 and D passage 21, E passage 22 is perpendicular, and in the same way concentric with C-channel 13; Dismountable connecting head 3 that is provided with respectively on A passage 11, B passage 12, C-channel 13, in order to connecting tube; On connecting head 3, be also provided with and accept body 31, accept that body 31 extends internally until contact with smart ball 2; Be provided with the first seal ring 4 accepting on body 31, in valve body 1,5, three the first seal rings 4 of the second seal ring are also housed for the opposite end of C-channel 13 and the second seal ring 5 is fixed on smart ball 2 in valve body 1.Because smart ball 2 is fixedly suspended from valve body 1 by the first seal ring 4 and the second seal ring 5, essence ball 2 does not directly contact with valve body 1, and meanwhile, valve body 1 and smart ball 2 adopt PVC material, under high temperature condition, its inflation speed is identical, also there will not be smart ball 2 and valve body 1 that card realization occurs and resembles.
