Abstract
The utility model discloses a high-strength ball valve which comprises a valve body, a valve seat and a ball. An O-shaped seal ring and a spring are disposed between the valve body and the valve seat. A graphite block is further disposed between the valve bock and valve seat. The valve seat is provided with a socket. An insert is disposed in the socket. A support structure is arranged between the valve body and one end of the valve seat, close to the ball. The support structure is disposed between the valve seat and the valve body, so that strength of the ball valve is guaranteed and manufacturing cost of the valve seat is reduced.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of high strength ball valve.
Background technique
One of widely used valve of ball valve, its working principle is the same with stopcock, all is to make valve opening and closing by rotary spool, but lighter than stopcock switch, relative volume is little, can make big-diameter ball valve.Ball valve sealing is reliable, and is simple in structure, easy to maintenance, and sealing surface and the spheroid closed state of being everlasting is difficult for by the medium erosion, thereby is widely used in industries such as oil, chemical industry, metallurgy.
Referring to shown in Figure 1, the spheroid 3 that existing ball valve generally comprises valve body 1, valve seat 2 and seals is provided with spring 4 and O-ring seals 5 between valve body 1 and the valve seat 2, offer slot on the valve seat, be provided with a nonmetallic plug-in unit 6 in the slot, the spheroid of ball valve is fixed, and does not produce movement behind the pressurized, after valve seat is subjected to hydrodynamic pressure, produce and move, so that plug-in unit can be pressed on the spheroid, seal with assurance, on valve seat, also be provided with a graphite block 7, be used for fire prevention.Leave certain space between the valve body of ball valve and the valve seat, slide in the valve body again to guarantee valve seat, in the prior art, intensity in order to ensure valve seat, and guarantee that plug-in unit can not come off, that generally the radius of valve seat can be done is larger, certainly will cause like this increase of manufacture cost.
Summary of the invention
The utility model purpose provides a kind of high strength ball valve, by the improvement to structure, has guaranteed the intensity of ball valve, and has saved manufacture cost.
The technical solution of the utility model is: a kind of high strength ball valve, comprise valve body, valve seat and spheroid, be provided with O-ring seals and spring between described valve body and the valve seat, also be provided with graphite block between described valve body and the valve seat, offer slot on the described valve seat, be provided with plug-in unit in the described slot, be provided with supporting structure between nearly described spheroid one end and the described valve body on the described valve seat.
Further technological scheme, described supporting structure comprises a support ring, and described support ring one end is arranged at the outside of described valve seat, and the other end of described support ring and described valve body are conflicted.
In the technique scheme, ball valve is made of valve body, valve seat and spheroid, and O-ring seals and spring are set between valve body and the valve seat, also be provided with graphite block between valve seat and valve body, be used for fire prevention, offer slot on the valve seat, nonmetallic plug-in unit is set in it, and plug-in unit contacts with spheroid realizes sealing.The utility model arranges a support ring near spheroid one end place on valve seat, this support ring one end is arranged on the valve seat, the other end and valve body are conflicted, support ring can adopt the PEEK material, because the PEEK material has certain elasticity, therefore can not affect the move left and right of valve seat in valve body, because support ring is conflicted between valve seat and valve body, so valve body can apply certain pressure to valve seat by support ring, so just guaranteed that valve seat has certain intensity, guaranteed the intensity of ball valve, and guarantee that plug-in unit can not deviate from, because the setting of support ring has been arranged, so just can reduce the radius of valve seat, can guarantee too the intensity of valve seat, save manufacture cost.
The utility model has the advantages that:
1. the utility model is by arranging support ring between valve seat and valve body, and support ring one end is arranged on the valve seat, and the other end and valve body are conflicted, and valve body can be implemented pressure to valve seat through support ring, thereby has guaranteed the intensity of ball valve;
2. the utility model has been guaranteed the intensity of ball valve by support ring is set, so that the radius of valve seat can reduce as compared with the past, has saved manufacture cost;
3. the utility model is simple in structure, and is easy to use, and is easy to realize, is fit to promote the use of.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation of prior art;
Fig. 2 is the utility model embodiment one structural representation.
Wherein: 1, valve body; 2, valve seat; 3, spheroid; 4, spring; 5, O-ring seals; 6, plug-in unit; 7, graphite block; 8, valve body; 9, valve seat; 10, spheroid; 11, O-ring seals; 12, spring; 13, graphite block; 14, plug-in unit; 15, support ring.
Embodiment
Embodiment one: referring to shown in Figure 2, a kind of high strength ball valve, comprise valve body 8, valve seat 9 and spheroid 10, be provided with O-ring seals 11 and spring 12 between described valve body 8 and the valve seat 9, also be provided with graphite block 13 between described valve body 8 and the valve seat 9, offer slot on the described valve seat 9, be provided with plug-in unit 14 in the described slot, be provided with supporting structure between nearly described spheroid 10 1 ends and the described valve body 8 on the described valve seat 9, described supporting structure comprises a support ring 15, described support ring 15 1 ends are arranged at the outside of described valve seat 9, and the other end of described support ring 15 and described valve body 8 are conflicted.
When ball valve is made, at valve seat support ring is set, the other end of this support ring and valve body are conflicted, support ring has certain elasticity, can not affect the move left and right of valve seat in valve body, because support ring is conflicted between valve seat and valve body, valve body can be exerted pressure to valve seat by support ring, so just guaranteed that valve seat has certain intensity, and guaranteed that plug-in unit can not deviate from, guaranteed sealing effect.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
