Abstract
The utility model relates to a liquid-sac ball valve comprising a valve body and a spool inside the valve body. One port of the valve body is provided with a bonnet, and the other port of the valve body is provided with a positioning ring. The valve body is provided with a flange integrated to the valve body. The valve body and the flange are integrated so that the ball valve is stable in structure; the ports of the valve body both fit the bonnet or positioning ring in a threaded manner, so that adjustment is facilitated.
Description
Technical field
The utility model relates to a kind of ball valve technical field, particularly a kind of liquid bag ball valve.
Background technique
existing liquid bag ball valve generally comprises valve body, spool, valve gap and flange plate, spool is positioned at valve body, valve gap is positioned at a port of valve body, valve gap coordinates with valve body screw thread, the position that limits spool, the another port of valve body coordinates with flange plate by screw thread, and flange plate is on the one hand for limiting the position of spool, on the other hand for coordinating with the flange plate on liquid bag, the position of fixing ball valve.But because flange plate and valve body are screw-thread fit, the two linking steady character is bad, in using process, valve body and flange plate easily produce looseningly, cause ball valve to produce and leak.
Model utility content
The purpose of this utility model is to provide a kind of liquid bag ball valve, has solved existing ball valve body and flange plate and has easily produced loosening technical problem.
For reaching, solve above-mentioned technical purpose, the utility model adopts following technological scheme to be achieved:
A liquid bag ball valve, the port that ball valve comprises valve body, be positioned at the spool of valve body, valve body is provided with valve gap, and the another port of valve body is provided with positioning ring, is provided with flange plate integrated with it on valve body.
Liquid bag ball valve as above, the inside of valve body another port is provided with screw thread, and the periphery of positioning ring is provided with screw thread, and positioning ring and valve body are screw-thread fit.
Liquid bag ball valve as above, the inside of a port of valve body is provided with screw thread, and the periphery of valve gap is provided with screw thread, and valve gap and valve body are screw-thread fit.
The beneficial effects of the utility model are: the utility model valve body and flange plate are one-body molded, stabilized structure; The port of valve body all coordinates with valve gap or positioning ring by screw thread, convenient adjusting.
Read by reference to the accompanying drawings after the detailed description of the utility model mode of execution, other features of the present utility model and advantage will become clearer.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of the utility model specific embodiment.
Fig. 2 is the structural representation of the utility model specific embodiment flange plate.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described:
As shown in Figure 1-2, the present embodiment has proposed a kind of liquid bag ball valve, ball valve comprises valve body 1, is positioned at the spool 2 of valve body 1, spool 2 coordinates with valve body 1 by O-ring seal 3, the top of one port spool 2 of valve body 1 is provided with valve gap 4, the periphery of valve gap 4 is provided with screw thread, the inside of valve body 1 is provided with screw thread, and valve gap 4 is screw-thread fit with valve body 1.The bottom of the another port spool 2 of valve body 1 is provided with positioning ring 5, the inside of valve body 1 another port is provided with screw thread, the periphery of positioning ring 5 is provided with screw thread, and positioning ring 2 is screw-thread fit with valve body 1, between spool 2 and positioning ring 5, by O-ring seal 3, seals.On valve body 1, be provided with flange plate 11 integrated with it, ball valve is combined with liquid bag by flange plate 11.
When ball valve is installed, spool 2 is placed in valve body 1, positioning ring 5 and valve body 1 are positioned spool 2 by screw-thread fit.Valve gap 4 is arranged on valve body 1, with valve body 1 screw-thread fit.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
