Abstract
The utility model relates to a hemisphere valve which comprises a valve body, a hemisphere body and a valve rod. A valve cavity and medium channels arranged on two sides of the valve cavity are arranged in the valve body, the hemisphere body is arranged in the valve cavity, the valve rod penetrates the valve body to be connected with the top of the hemisphere body, a supporting shaft is arranged on the valve body at a position corresponding to the bottom of the hemisphere body, a valve seat matched with the hemisphere body is arranged on one side of the valve cavity, a protruding ring surrounding the medium channels is arranged on one side of the valve cavity, the valve seat is annular, and the outer diameter of the valve seat is matched with the inner diameter of the protruding ring. The valve seat is further provided with an outwards protruding limit side, the limit side is arranged on the other side of the protruding ring opposite to the hemisphere body, a pressing ring is arranged on the other side of the valve seat opposite to the protruding ring, and the pressing ring and inner walls of the medium channels are connected through threads in a matched mode. The hemisphere valve has the advantages of being easy to assemble and good in matching effect of the valve seat and the hemisphere body.
Description
Technical field
The utility model relates to a kind of semispherical valve.
Background technique
Semispherical valve, generally include valve body, hemisphere and valve rod, the medium channel that is provided with valve pocket in the valve body and is arranged on the valve pocket both sides, hemisphere places in the valve pocket, and described valve rod passes valve body and is connected with hemispheroidal top, and the corresponding hemisphere bottom position of valve body is provided with back shaft, valve pocket one side is provided with the valve seat that matches with hemisphere, it is little that semispherical valve has an opening force, closes and can abolish the fouling obstacle, realizes good seal performance, characteristics such as wear-resisting.The wear-resisting corrosion material of semispherical valve, thereby be widely used at water, steam, sewage, petrochemical industry, rock gas, two-phase mediums such as solution and ore pulp, and the desirable transmission equipment of dirty air etc.Yet existing semispherical valve, its valve seat are difficult to assembling, and valve seat and hemisphere fiting effect are not good.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of easy assembling and valve seat to cooperate better semispherical valve with hemisphere.
For achieving the above object, the utility model provides following technological scheme: a kind of semispherical valve, comprise valve body, hemisphere and valve rod, the medium channel that is provided with valve pocket in the valve body and is arranged on the valve pocket both sides, hemisphere places in the valve pocket, described valve rod passes valve body and is connected with hemispheroidal top, the corresponding hemisphere bottom position of valve body is provided with back shaft, valve pocket one side is provided with the valve seat that matches with hemisphere, described valve pocket one side is provided with the bulge loop around medium channel, described valve seat arranges in the form of a ring, and the external diameter of valve seat and the suitable setting of the internal diameter of bulge loop, described valve seat also is provided with the position-limited edge of evagination, and described position-limited edge places the relative hemisphere opposite side of bulge loop, the relative bulge loop opposite side of described valve seat is provided with pressure ring, and described pressure ring is connected by screw-thread fit with the inwall of medium channel.
By adopting technique scheme, during assembling, earlier valve seat is packed into by medium channel, valve seat is matched with bulge loop, and then pressure ring screwed in compress valve seat, thereby make valve seat be fixed between bulge loop and the pressure ring, and make valve seat can with hemisphere can be good cooperate.
The utility model further is set to: be folded with elastic seal ring between described valve seat and the bulge loop.
By adopting technique scheme, make and to play good sealing between valve seat and the bulge loop.
The utility model further is set to: described valve rod is fixedlyed connected by screw rod with the hemisphere top.
By adopting technique scheme, make hemisphere have bigger moment of torsion.
Below in conjunction with accompanying drawing the utility model is further described:

Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment
Referring to accompanying drawing 1 and accompanying drawing 2, the disclosed semispherical valve of the utility model, comprise valve body 1, hemisphere 2 and valve rod 3, the medium channel 102 that is provided with valve pocket in the valve body 1 and is arranged on valve pocket 101 both sides, hemisphere 2 places in the valve pocket 101, described valve rod 3 passes valve body 1 and is connected with the top of hemisphere 2, valve body 1 corresponding hemisphere 2 bottom positions are provided with back shaft 4, valve pocket 101 1 sides are provided with the valve seat 5 that matches with hemisphere 2, described valve pocket 101 1 sides are provided with the bulge loop 103 around medium channel 102, described valve seat 5 arranges in the form of a ring, and the suitable setting of the internal diameter of the external diameter of valve seat 5 and bulge loop 103, described valve seat 5 also is provided with the position-limited edge 501 of evagination, described position-limited edge 501 places bulge loop 103 relative hemisphere 2 opposite sides, described valve seat 5 relative bulge loop 103 opposite sides are provided with pressure ring 6, and described pressure ring 6 is connected by screw-thread fit with the inwall of medium channel 102.By adopting technique scheme, during assembling, earlier valve seat 5 is packed into by medium channel 102, valve seat 5 is matched with bulge loop 103, and then pressure ring 6 screwed in compress valve seat 5, thereby make valve seat 5 be fixed between bulge loop 103 and the pressure ring 6, and make valve seat 5 can with hemisphere 2 can be good cooperate.
Present embodiment further is set to: be folded with elastic seal ring 8 between described valve seat 5 and the bulge loop 103.By adopting technique scheme, make and to play good sealing between valve seat 5 and the bulge loop 103.
Present embodiment further is set to: described valve rod 3 is fixedlyed connected by screw rod 7 with hemisphere 2 tops.By adopting technique scheme, make hemisphere 2 have bigger moment of torsion.
