Abstract
The utility model relates to a ball valve. The ball valve comprises a valve body, wherein the valve body is internally provided with a valve core; the upper end of the valve core is connected with the lower end of a valve rod; the upper end of the valve rod penetrates through the wall of the valve body and is arranged in a valve rod drum; the lower end of the valve rod drum is connected with the valve body; the side surface of the valve rod drum is provided with a limiting groove along the radial groove of the valve rod drum; the upper part of the valve rod, which corresponds to the limiting groove, is provided with a connecting hole; the valve rod is connected with one end of a handle arranged in the connecting hole by a screw at the top of the valve rod; and the other end of the handle penetrates through the limiting groove on the valve rod drum. A sealing ring is arranged between the valve rod and the valve rod drum, and a pressing ring is arranged above the sealing ring. A drum cover is arranged at the top of the valve rod drum. The ball valve has the beneficial effects of reasonable structure, good sealing performance, high mechanical strength and long service life.
Description
Technical field
The utility model relates to a kind of ball valve.
Background technique
Ball valve in the market, at first, the handle of ball valve is directly to be enclosed within on the valve rod; And handle is to adopt tinsel to process, because ball valve has medium such as water to pass through in use, adheres to some media on the handle sometimes; Simultaneously; Handle is frequently pulled in use, and the mechanical strength of tinsel is relatively low, so handle fracture or bending deflection easily in use.Secondly, the slewing area of handle is to receive the shoulder block on the valve body to stop realization through an elbow, after ball valve uses a period of time, and the elbow meeting bending deflection that tinsel is processed, even break off, ball valve can not be used.Once more, owing to receive the restriction of ball-valve structure, the valve rod in the ball valve is generally thinner, exists the joint of valve rod and spool the problem that ruptures or break away from usually to occur.
The model utility content
The purpose of the utility model provides a kind of ball valve, overcomes the deficiency of above-mentioned aspect in the existing product.
The purpose of the utility model is to realize through following technological scheme:
A kind of ball valve comprises valve body, is provided with spool in the said valve body; The spool upper end is connected with the valve rod lower end, and the valve rod upper end is passed the body wall of valve body and is arranged in the valve stem cylinder, and the valve stem cylinder lower end is connected with valve body; The valve stem cylinder side radially is provided with restraining groove along valve stem cylinder; The corresponding said restraining groove in valve rod top is provided with attachment hole, and valve rod is connected with handle one end in being arranged at attachment hole through the screw at valve rod top, and the handle the other end passes the restraining groove on the valve stem cylinder.Be provided with seal ring between said valve rod and the valve stem cylinder, the seal ring top is provided with retainer ring.Said valve stem cylinder top is provided with cover.
The beneficial effect of the utility model is: good airproof performance; One end of handle is inserted in the interior screw of also passing through of attachment hole of valve rod, and handle is connected firmly, and adopts this kind structure simultaneously, and the connecting end of handle and valve rod can adopt cylindrical, and mechanical strength is high; Restraining groove on the valve stem cylinder in use can not be out of shape or wear and tear basically, so the rotation angle of handle deviation can not occur yet, and the position that makes ball valve spool when opening and closing very accurately; Valve rod can adopt thicker structure, avoids the joint of valve rod and spool the problem that ruptures or break away from usually to occur, and improves the quality of products, and increases the service life.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the described ball valve of the utility model embodiment;
Fig. 2 is the stereogram of the described ball valve of the utility model embodiment.
Among the figure:
1, valve body; 2, spool; 3, valve rod; 301, attachment hole; 4, valve stem cylinder; 401, restraining groove; 5, screw; 6, handle; 7, seal ring; 8, retainer ring; 9, cover.
Embodiment
Shown in Fig. 1-2, the described a kind of ball valve of the utility model embodiment comprises valve body 1; Be provided with spool 2 in the said valve body 1; Spool 2 upper ends are connected with valve rod 3 lower ends, and valve rod 3 upper ends are passed the body wall of valve body 1 and are arranged in the valve stem cylinder 4, and valve stem cylinder 4 lower ends are connected with valve body 1; Valve stem cylinder 4 sides radially are provided with restraining groove 401 along valve stem cylinder 4; The corresponding said restraining groove 401 in valve rod 3 tops is provided with attachment hole 301, the screw 5 of valve rod 3 through valve rod 3 tops be arranged at attachment hole 301 interior handle 6 one ends and be connected, handle 6 the other ends pass the restraining groove 401 on the valve stem cylinder 4.Be provided with seal ring 7 between said valve rod 3 and the valve stem cylinder 4, seal ring 7 tops are provided with retainer ring 8.Said valve stem cylinder 4 tops are provided with cover 9.
Wherein, Valve stem cylinder 4 is connected as a single entity with valve body 1; Handle 6 can be that rotate in the axle center with valve rod 3, and the angle of rotation receives restraining groove 401 restrictions, and the angle of restraining groove 401 can be confirmed as 60 ° or 90 ° etc. according to actual needs; The cover 9 at valve stem cylinder 4 tops can adopt materials such as metal or plastics, and the major function of cover 9 is to prevent that foreign material etc. from getting into valve stem cylinder 4.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technological scheme, all drops within the protection domain of the utility model.
