Abstract
The utility model discloses a three-way half-ball valve which comprises a valve (11), a valve shaft (4) and a valve element. The valve element is a half-ball-shaped valve element (12), a ball-shaped sealing surface (1203) which is sealed with a ball surface (1103) of the valve (11) is arranged in the middle of the half-ball-shaped valve element (12), and a gap is reserved between the valve shaft (4) and a shaft sleeve of the valve (11). The three-way half-ball valve has the advantages of low opening resistance, simple structure and reliable performance.
Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of three-way half ball valve.
Background technique
Existing threeway discharging ball valve is because the gap between spool (threeway spheroid) and valve body easily enters slip medium, after dry, spool (threeway spheroid) and valve body are bonded together, during rotational valve core (threeway spheroid), resistance is very large again, so that cannot Open valve.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of three-way half ball valve that resistance is little of opening.
In order to solve the problems of the technologies described above, the three-way half ball valve that the utility model provides, comprise valve body, valve shaft and spool, described spool is hemisphere spool, the middle part of described hemisphere spool is provided with the Spherical Seals face with the ball face sealing of described valve body, between described valve shaft and the axle sleeve of described valve body, has gap.
Described valve body adopts separation structure in upper and lower symmetric type.
Described valve shaft is provided with limiting board.
On the described Spherical Seals face of described hemisphere spool, heap is welded with abrasion resistance alloy.
Adopt the three-way half ball valve of technique scheme, because spool adopts hemisphere spool, reduced the area of contact of 90% spool (1/4 spheroid) with valve body, the also corresponding minimizing of the bonding resistance of medium; Meanwhile, due between the upper lower valve shaft that connects spool (1/4 spheroid) and the axle sleeve of valve body, there is gap, during spool (1/4 spheroid) rotation, can has trace to move radially, prevent the rotation of media particle jam spool (1/4 spheroid).Therefore, resistance during valve opening and closing reduces greatly, can realize manpower opening/shutting valve.
In sum, the utility model is a kind ofly to open that resistance is little and simple in structure, the three-way half ball valve of reliable performance.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, the utility model is mainly comprised of nut 1, double threaded screw 2, screw 3, valve shaft 4, sleeve 5, handle 6, seal ring 7, adjusting nut 8, limiting board 9, flat key 10, valve body 11 and hemisphere spool 12 etc.
Referring to Fig. 3 and Fig. 4, valve body 11 is upper and lower symplex structure, double threaded screw 2 is through the bolt hole 1102 on valve body 11, upper and lower valve body is connected to integral body, and be locked with nut 1, thereby form complete three way valve, wherein through hole 1101 is material feeding mouth, through hole 1104 is straight-through discharge port, and through hole 1105 is bypass discharge port.
Referring to Fig. 6, hemisphere spool 12 is hemispherical dome structure, and middle part is provided with Spherical Seals face 1203, and on its spherical seal surface 1203, heap is welded with abrasion resistance alloy, with valve body 11(Fig. 3) in sphere 1103 coordinates and forms valve seal pair.
Referring to Fig. 5, valve shaft 4 bottoms are cylindrical body 406, insert spool 12(Fig. 6) on axis hole 1201, and pack flat key 10 into keyway 407 on valve shaft 4 and the keyway 1202 on spool 12, thereby valve shaft 4 and spool 12 are connected to integral body, between valve shaft 4 and the axle sleeve of valve body 11, have gap.Valve shaft 4 tops are prism, are equipped with circular hole 401 on each prismatic surface; Valve shaft 4 middle part cylindrical bodys 403 are provided with annular groove 404, and rubber seal 7 is placed in one, and stop dielectric leakage.Upper and lower valve shaft is arranged symmetrically with.
Referring to Fig. 7, the endoporus 801 of adjusting nut 8 coordinates with the middle part cylindrical body 403 of valve shaft 4, and threaded circular cylinder 803 coordinates with (Fig. 4) tapped hole 1108 on valve body 11; Plane 804(Fig. 8) push down the round boss 405 on valve shaft 4; With special tool, insert in aperture 802, rotatable adjusting nut 8, by this, capable of regulating spool 12 in valve body 11 in suitable position.
Referring to Fig. 9, Figure 10, the prism hole 901 in limiting board 9 coordinates with the prismatic surface 402 on valve shaft 4; Bottom notch 903 is stuck on the limiting stopper 1107 on valve body 11; Restriction spool 8 can only 90-degree rotation.On it, can there is " pass " word 902, the passage of indication in closed condition.Sleeve 5(Figure 11) prismatic surface 503 on coordinates assembling with the prismatic surface 402 on valve shaft 4, and the prismatic surface number of valve shaft 4 and sleeve 5 is 2-12, in order to transmit the moment of torsion from handle 6, drives hemisphere spool 12 to rotate.
The utility model adopts hemisphere spool 12, has reduced the area of contact of 90% spool (1/4 spheroid) with valve body, the also corresponding minimizing of the bonding resistance of medium; Simultaneously, owing to connecting referring to having gap between the upper lower valve shaft 5 of (1/4 spheroid) and the axle sleeve of valve body 11, while hemisphere spool 12(1/4 spheroid) rotating, can have trace to move radially, prevent media particle jam hemisphere spool 12(1/4 spheroid) rotation.Therefore, resistance during valve opening and closing reduces greatly, can realize manpower opening/shutting valve.
