Embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
As shown in Figure 1, a kind of two-way no friction hard-sealing elastic seat ball valve, by valve body 25, valve gap 6, sealing gasket 13 and control end constitute, be provided with elastic seat 24 and through hole spheroid 26 in the described valve body 25, joint shaft bearing 14, bearing support 15, described control end includes in valve gap 6 bottoms supporting sleeve 23 is housed, valve rod 7 is equipped with at the middle part, hard sealing gasket 8, soft seal assembly 20, nut 19 is adjusted in sealing, bearing 18, dust-proof cover 17, the back of the body female 5, anchor plate 4, adjust nut 3 and end thereof the handwheel 16 that links to each other with valve rod 7 upper ends is housed, gland 2, clamping bolt 1, its described supporting sleeve 23 outsides be provided with positioning screwn 21 that two shape chutes 22 and described valve gap 6 be provided with mutually embedding slide, its upper end is provided with spring latch 10 and is complementary with the groove 9 that described valve rod 7 steps are provided with below, its inside, lower end is provided with two cylinder type slide-bars 12 and contacts with the tiltedly inclined to one side post 11 on described spheroid 27 tops, and described valve rod 7 lower ends and described supporting sleeve 23 tops are linked by screw buckle.
As shown in Figure 2, described elastic seat 24 is welded with a long tube 27 by valve body 24 inboards, and be provided with certain slit 28, long tube 27 the other ends and the welding of valve body 25 outlet end, described valve body 24 is provided with inner side slot 29 and outer side slot 30, and valve body 24 inboard upward built-up welding have the cemented carbide sealing surface 31 that is complementary with 26 shapes of through hole spheroid.Its effect is when the medium forward flow, spheroid is close to sealing surface, because spheroid 26 is to do oscillating motion, in order to make 26 of spheroids still be in preferable sealing state with sealing surface 31, this moment, elastic valve body 24 just can play the regulating action of fine motion, when the medium reverse flow, because inner side slot 29 that valve body 24 is provided with and outer side slot 30 and long tube 27 stitch 28 with the space of valve seat 24, under pressure action of medium, make sealing surface of seat 31 produce trace movement, benefit has been appreciated the trace movement of spheroid, has guaranteed sealing, has avoided the possibility of leaking.
The utility model working procedure is as follows: when rotating handwheel 16, the valve rod 7 that links with it also rotates, by screw buckle pulling supporting sleeve 23 to up or to downward movement, because two the shape grooves 22 in supported cover 23 outsides and the restriction of positioning screwn 21, can only spacingly revolve and turn 90 degrees, supporting sleeve 23 underparts two cylinder type slide-bars 12 force the tiltedly inclined to one side post 11 on spheroid 26 tops to produce the wedge power, making spheroid 26 break away from elastic seat 24 continues to up, the spring latch 10 of supporting sleeve 23 upper ends enters in the groove 9 below valve rod 7 steps, guaranteed that supporting sleeve 23 resets, the straight trough section that is J-shaped groove 22 stops, supporting sleeve 23 revolved synchronously with valve rod 7 and turn 90 degrees this moment, spheroid 26 revolves and turn 90 degrees subsequently, the consistent opening state that is with the pipe diameter direction of its spheroid 26 through holes, media flow; Otherwise, when supporting sleeve 23 when descending, at first spheroid 26 revolves and turn 90 degrees, reset and follow-uply continue descendingly,, make cylinder type slide-bar 12 produce another kinds and push away wedge power owing to be subjected to the tiltedly partially effect of post 11 of spheroid 26 tops, force spheroid 26 and elastic seat 24 to be close to, cut off media flow, be closed condition.
