Bar top is installed by handwheel；The spheroid bottom is installed by lower bearing；The outer surface of spheroid is scribbled and is set on the outside of oil film, and the oil film
Put sealing ring；Spheroid top side arranges valve seat, and the valve seat is connected with the valve body by spring；In the spheroid
Portion arranges manhole；Fixed by fixing bolt between the valve body.
Preferably, the V-shaped structure of the body cavity.
Preferably, the valve seat is provided with four, and the spheroid top is respectively provided with two, and the valve seat and valve body with bottom
Between be respectively provided with the spring.
Preferably, the sealing ring is tubular structure, and is close to the valve body medial wall, and the sealing ring is near spheroid one
The thickness and diameter of side is all higher than the thickness and diameter of its opposite side.
Preferably, the outer surface of spheroid is evenly coated with oil film.
The beneficial effects of the utility model are：This kind of fixed type ball valve body is removable, easy to maintenance, applies one in spherome surface
Layer oil film, that is, enhance sealing, reduce operation moment of torsion again, valve rod is down-mounting type, prevent pressurized fly out, body cavity be in V
Type, when the valve is closed, produces wedge shape shearing effect, not only there is self-cleaning function but also can prevent spheroid between v-notch and valve seat
Stuck, eliminate high-velocity fluid and valve seat local is washed away, valve seat is connected by spring with valve body, increases the contract of spheroid and valve seat
Right, prevent spheroid from shifting because pressure is excessive, extend sealing ring and inclined be close to valve body medial wall, spheroid with close
Seal first contacts diameter of its seal diameter more than other parts, effectively reduces erosion of the exit fluid to sealing ring, has
Good economic benefit and social benefit, are suitable for promoting the use of.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment.Embodiment in based on this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Refer to shown in Fig. 1-2, a kind of Fixed ball valve, including valve body 11 and be arranged on the ball of 11 inner chamber of the valve body
Body 10,10 one end of the spheroid connect valve rod 8, and 8 bottom of valve rod connection upper bearing (metal) 1；8 top of the valve rod is installed by handwheel
7；10 bottom of the spheroid is installed by lower bearing 6；10 outer surface of the spheroid scribble arrange on the outside of oil film 12, and the oil film 12 close
Seal 5；10 top side of the spheroid arranges valve seat 3, and the valve seat 3 is connected with the valve body 11 by spring 9；The ball
Manhole 4 is set inside body 10；Fixed by fixing bolt 2 between the valve body 11.
As a kind of technical optimization scheme of the present utility model, the V-shaped structure of 11 inner chamber of the valve body, be conducive to adjusting stream
Amount, and it is beneficial to automated cleaning.
Used as a kind of technical optimization scheme of the present utility model, the valve seat 3 is provided with four, 10 top of the spheroid and bottom
End is respectively provided between two, and the valve seat 3 and valve body 11 and is respectively provided with the spring 9, increases the compatible degree of spheroid and valve seat, prevents
Only spheroid shifts because pressure is excessive.
Used as a kind of technical optimization scheme of the present utility model, the sealing ring 5 is tubular structure, and is close to the valve body
11 medial walls, thickness and diameter of the sealing ring 5 near 10 side of spheroid are all higher than the thickness and diameter of its opposite side, effectively
