Description
Technical field
The utility model relates to a kind of valve body, and more particularly, it relates to a kind of wear-resistant, the spherical valve body of good seal performance.
Background technique
The sealing of stop valve is made up of valve clack sealing surface and sealing surface of seat, valve rod drives flap to do vertical motion along the center line of valve seat, open highly less in opening-closing process, be easy to the adjustment of flow, and manufacture easy to maintenance, pressure is applied widely, from working life, in valve opening and closing process between flap and sealing surface of seat without relative sliding, do not rub, but because valve body inner flow passage is more tortuous, fluid flow resistance is large, fluid can wash away pipeline, especially when flap is opened, fluid understands fast flush near rising pipe side valve seat and flap, can seal asymmetric after multiple switching, sealability is caused to decline.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of wear-resistant, the spherical valve body of good seal performance.
For achieving the above object, the utility model provides following technological scheme:
A kind of spherical valve body, comprise valve body, described valve body comprises inlet valve pipe, outlet valve pipe and valve gap connecting tube, described valve body is provided with valve seat, the one side of the relative valve gap connecting tube of described valve seat is provided with ring-type projection, described valve gap connecting tube madial wall and valve seat joint are provided with ring-type dashpot, and described ring-type dashpot is connected with outlet pipe, and described valve seat is provided with channelization angle relative to the side of inlet valve pipe.
Preferably, the cross section of described ring-type projection is trapezoidal, triangle or rectangular.
Preferably, described ring-type dashpot both sides are provided with arc-shaped corner.
Preferably, the described ring-type dashpot degree of depth is less than 1/2nd of valve body thickness.
Compared with prior art, the beneficial effects of the utility model are: valve body is provided with valve seat, the one side of the relative valve gap connecting tube of described valve seat is provided with ring-type projection, have and necessarily protrude shape, add sealing surface, ensure that the good contact of flap bottom surface and sealing surface of seat, and manufacture simple, described valve body madial wall and valve seat joint are provided with ring-type dashpot, ring-type dashpot will be communicated with outlet pipe with flap away from rising pipe side valve seat, balance valve seat and flap near rising pipe side and the pressure away from rising pipe side, valve seat is made to obtain consistent with flap wearing and tearing, be not easy to cause sealing asymmetric, considerably increase kind of an abrasion resistance properties, sealing is made to obtain good maintenance, can seal asymmetric after solving multiple switching, cause the problem that sealability declines, and ring-type dashpot does not destroy being sealed and matched of flap sidewall and valve body inner side surface, make flap that fluid can be stoped to enter valve gap connecting tube place, greatly reduce the possibility of valve body seepage, make valve seal performance better, and described valve seat is provided with channelization angle relative to the side of inlet valve pipe, decrease fluid and dynamics is washed away to valve seat, improve the stability of valve seat, greatly reduce the possibility of valve body seepage.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art 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, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the generalized section of the utility model spherical valve body;
Fig. 2 is A place enlarged view in Fig. 1.
Description of reference numerals: 1, valve body; 2, valve gap connecting tube; 3, inlet valve pipe; 4, outlet valve pipe; 5, valve seat; 6, annular projection; 7, ring-type dashpot; 8, channelization angle.
Embodiment
With reference to accompanying drawing, the utility model spherical valve body embodiment is described in further details.
See figures.1.and.2, a kind of spherical valve body 1, comprise valve body 1, described valve body 1 comprises inlet valve pipe 3, outlet valve pipe 4 and valve gap connecting tube 2, described valve body 1 is provided with valve seat 5, the one side of the relative valve gap connecting tube 2 of described valve seat 5 is provided with ring-type projection, have and necessarily protrude shape, add sealing surface, ensure that the good contact of flap bottom surface and valve seat 5 sealing surface, and manufacture simple, the cross section of described ring-type projection is trapezoidal, triangle or rectangular, in the present embodiment, the cross section of ring-type projection is trapezoidal, because cross section is that trapezoidal ring-type projection has larger sealing surface, and cross section is trapezoidal ring-type projection effectively can guide fluid, make fluid can not cause larger impact to flap bottom surface and valve seat 5 sealing surface, add the working life of valve seat 5, described valve body 1 madial wall and valve seat 5 joint are provided with ring-type dashpot 7, ring-type dashpot 7 will be communicated with outlet pipe with flap away from rising pipe side valve seat 5, balance valve seat 5 and flap near rising pipe side and the pressure away from rising pipe side, valve seat 5 is made to obtain consistent with flap wearing and tearing, be not easy to cause sealing asymmetric, considerably increase kind of an abrasion resistance properties, sealing is made to obtain good maintenance, can seal asymmetric after solving multiple switching, cause the problem that sealability declines, and ring-type dashpot 7 does not destroy being sealed and matched of flap sidewall and valve body 1 inner side surface, make flap that fluid can be stoped to enter valve gap connecting tube 2 place, greatly reduce the possibility of valve body 1 seepage, make valve body 1 sealability better, and described valve seat 5 is provided with channelization angle 8 relative to the side of inlet valve pipe 3, decrease fluid and dynamics is washed away to valve seat 5, improve the stability of valve seat 5, greatly reduce the possibility of valve body 1 seepage.
In the present embodiment, described ring-type dashpot 7 both sides are provided with arc-shaped corner, ring-type dashpot 7 is connected with valve seat 5 inclined-plane, ensure that the steadily excessive of fluid, make wearing and tearing less, make valve body 1 wear-resistant, described ring-type dashpot 7 degree of depth is less than 1/2nd of valve body 1 thickness, both ensure that the wear resistance of valve body 1 in turn ensure that the steadiness of valve body 1.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
