Abstract
The utility model relates to a bidirectional non-wearing ball valve, which is composed of a valve body, a valve cover and a control end, wherein, the valve body is provided with a ball body and a valve seat inside, and the control end is composed of a supporting seat, a supporting block, a valve rod and a seal gasket, which are arranged in the valve cover. The lower end of the valve rod is connected with a groove on the upper end of the ball body in the valve body, the upper end of the valve rod is provided with a hand wheel, and the upper part of the valve rod is provided with concave sliding groove. The valve cover is fixedly connected with the valve body, and the upper end of the valve cover is provided with a supporting frame which is provided with a ball pin and a set screw inside, wherein, the end of the ball pin is embedded into the concave sliding groove on the valve rod. The inner side of the supporting frame is provided with a positioning ball and a set screw. The center of the end of the hand wheel is provided with a positioning bolt. The utility model has the advantages of compact structure, no medium, zero wear, small torque, and simple and easy operation.
Description
The utility model relates to a kind of two-way nothing wearing and tearing ball valve that is used for industries such as oil, chemical industry, electric power, metallurgy.
Traditional O type cuts off ball valve, and the ball core rubs with valve seat in rotation process, and serious wear easily causes leakage.In addition, easily accumulate medium in the valve body, hindered the motion of ball core.Simultaneously, ball core driving torque is big, the operation effort.
The problem that the purpose of this utility model exists at prior art and provide a kind of nothing to deposit medium, do not have wearing and tearing, bidirectional flow to, driving torque is little, operation is light, open and close the two-way rapidly nothing ball valve that weares and teares.
The purpose of this utility model is achieved in that a kind of two-way nothing wearing and tearing ball valve, it is by valve body, valve gap and control end constitute, through hole spheroid and valve seat are housed in the valve body, it is characterized in that control end comprises by the valve gap internal upper part is equipped with bearing, a piece is equipped with in the bottom, the centre is equipped with valve rod and the outside and sealing gasket is housed is assembled into, valve rod lower end and spheroid upper end groove partially link, the valve rod upper part is provided with " the type concave slide groove; valve gap is affixed by bolt and valve body; filler is housed between valve rod and the valve gap and binds; support is equipped with in the valve gap upper end; be provided with pearl ball pin and jackscrew in the support; pearl ball pin end embeds in the concave slide groove of valve rod, handwheel is equipped with in the valve rod end of support top, and positioning bead ball and jackscrew are equipped with under the handwheel and the inboard of support, and holding down bolt is equipped with at center, handwheel end.Its working principle: shake handwheel, coupled valve rod is by the location turn of positioning bead ball, and pearl ball pin moves in the valve rod concave slide groove, reduced the power of holding tightly that valve rod slides up and down, valve rod upwards slides, and bearing is also up thereupon, make a piece of its underpart produce top wedge power, impel spheroid to depart from valve seat, produce the gap, valve rod half-twist then, spheroid is followed half-twist, does not produce friction with valve seat, wearing and tearing have been reduced, the spheroid through hole is consistent with pipe diameter, is opening state, and medium can flow.Otherwise after elder generation did 90 ° of rotations that reset, valve rod was to lower slider, and bearing also moves down simultaneously, and the piece generation top wedge power by opposite side makes spheroid compress valve seat and is closed state, promptly cuts off media flow.The position degree of its spheroid rotation is regulated by the holding down bolt at center, handwheel end.
Nos medium in the utility model compact structure, valve body, do not have wear and tear, moment of torsion is little, operation is light, bidirectional flow to, purposes is extremely extensive, has popularizing value.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is the utility model structural representation.
As shown in Figure 1, a kind of two-way nothing wearing and tearing ball valve, it is by valve body (17), valve gap (9) and control end constitute, through hole spheroid (16) and valve seat (14) are housed in the valve body (17), its control end comprises the bearing (11) that is equipped with by valve gap (9) internal upper part, the piece (13) that be equipped with the bottom, the sealing gasket (12) that be equipped with in the valve rod that be equipped with the centre (10) and the outside is assembled into, valve rod (10) lower end and spheroid (16) upper end and inclined to one side groove link, valve rod (10) upper part is provided with " type concave slide groove (18); valve gap (9) is affixed by bolt (15) and valve body (17); filler (8) and bind (7) are housed between valve rod (10) and the valve gap (9); support (4) is equipped with in valve gap (9) upper end; be provided with pearl ball pin (5) and jackscrew (6) in the support (4); pearl ball pin (5) end embeds in the concave slide groove (18) of valve rod (10), handwheel (2) is equipped with in valve rod (10) end of support (4) top, positioning bead ball (3) and jackscrew (19) are equipped with under the handwheel (2) and the inboard of support (4), and holding down bolt (1) is equipped with at handwheel (2) center, end.
