Abstract
A ball vale with a window comprises a valve body, a valve cap, a valve seat, a ball, a valve rod, a set screw and a valve rod cap, wherein the set screw is fixed in the radial side of the valve rod, the valve body is provided with a 90-degree notch corresponding to the set screw, which is used for limiting the set screw, the lower end of the valve rod cap is screwed on the valve body, moreover, the valve rod cap is not in contact with the valve rod to cover the periphery of the valve rod, and the upper end of the valve rod cap is provided with the window through which the set screw can be seen. The set screw is utilized to control the opening and closing positions of the ball valve, the valve rod cap is utilized to prevent the misoperation of the ball valve and proof dust, meanwhile, an operator can conveniently observe the opening or closing state of the valve through the window structure, and therefore the defects of easy dust accumulation and easy misoperation of the valve rod of the conventional ball valve are improved.
Description
Technical field
The utility model relates to the pipeline valve field, in particular to a kind of ball valve with form.
Background technique
The main feature of ball valve is compact structure own, and sealing is reliable, and is simple in structure; Easy to maintenance, sealing surface and the sphere closed state of being everlasting is difficult for by the medium erosion; Be applicable to general work media such as water, solvent, acid and rock gas; But also be applicable to the medium that operating conditions is abominable, like oxygen, hydrogen peroxide, methane and ethene etc., be widely used in every profession and trade.
Yet adopt of existing ball valve exposed valve rod more, not only be subject to dust and invade and harass, and to the misoperation of valve rod, therefore, on this problem points, existing ball valve still has very big room for improvement easily.
The model utility content
To the deficiency of existing technology, the purpose of the utility model is: comprise valve body, valve gap, valve seat, spheroid and valve rod, it is characterized in that; Also comprise positioning screwn and valve thimble; Wherein, positioning screwn is fixed in the radial side of valve rod, and it is 90 ° otch that valve body is provided with central angle corresponding to positioning screwn; Be used to limit the angle of swing of said positioning screwn; The lower end of the said valve thimble said valve body that is threaded, and said valve thimble not cover at said valve rod peripheral with not contacting said valve rod, the upper end of said valve thimble is provided with the form that can see said positioning screwn.
Wherein, the inside, upper end of said valve thimble is provided with draw-in groove;
Wherein, said form is fixed in the said draw-in groove.
Wherein, said form is PVC plastic board or poly (methyl methacrylate) plate.
Adopt the technological scheme of the utility model, can utilize positioning screwn to control the switching position of ball valve, utilize the combination of valve thimble and window structure to prevent misoperation ball valve; And prevent dust; Simultaneously, window structure is convenient to the on off state that operator observe valve, thereby; Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be:
1, can prevent misoperation to valve rod;
2, dust protection;
3, be easy to grasp the on off state of ball valve.
Description of drawings
Fig. 1 is the utility model one embodiment's a plane structure schematic representation;
Fig. 2 is the perspective view of the utility model one embodiment's a part.
Description of reference numerals: 1-valve body; The 2-valve gap; The 3-valve seat; The 4-spheroid; The 5-valve rod; The 6-valve thimble; The 7-positioning screwn; The 8-form; The 9-draw-in groove.
Embodiment
Below in conjunction with accompanying drawing, the technical characteristics and the advantage of the utility model are done more detailed explanation, so that the utility model can more fully be understood.
Like Fig. 1 and shown in Figure 2, be respectively the utility model one embodiment's plane structure schematic representation and perspective view, wherein; Valve body 1, valve gap 2, valve seat 3, spheroid 4 and valve rod 5 etc. constitute existing ordinary ball valve; The utility model improves on this ordinary ball valve basis, that is, and and in order to prevent misoperation to ball valve; Valve thimble 6 is not contacted valve rod 5 ground cover at valve rod 5 peripheries; Valve thimble 6 is fixed through being threaded with valve body 1 near an end of valve body 1, and the other end of valve thimble 6 (upper end) inboard is provided with draw-in groove 9, and the mode through interference fit such as PVC plastic board or poly (methyl methacrylate) plate is fixed in the draw-in groove 9; Form form 8; Make form 8 do not contact valve rod 5 the upper-end surface cover at the upper end of valve rod 5, and can clearly see the state of positioning screwn 7, fixing positioning screwn 7 on valve rod 5 radial side as fixed component through form 8; Valve body 1 have central angle be 90 ° otch with the angle of swing of restriction positioning screwn 7, make positioning screwn 7 in 90 ° of otch and can and valve body 1 between can control the switch of ball valve through 90 ° of rotation positioning.
Thus, when safety valve is overhauled, can know clearly the open and-shut mode of ball valve through form 8; If the ball valve valve is in open mode,, can open valve thimble 6 with reference to Fig. 2; Positioning screwn 7 is rotated counterclockwise 90 °, positioning screwn 7 is supported terminate in the limit structure opposite side, thus throttle down; Block medium, overhaul then; And when the valve proper functioning,, therefore can prevent misoperation, and can protect valve rod 5 dust to invade and harass to valve rod 5 because the protective action of valve thimble 6 and form 8 can not be operated valve rod 5 easily.
In sum, adopt said structure, make the utility model compare and following advantage is arranged with existing structure:
1, can prevent misoperation to valve rod;
2, dust protection;
3, be easy to grasp the on off state of ball valve.
More than explanation is just illustrative as far as the utility model; And nonrestrictive, those of ordinary skills understand, under the situation of spirit that does not break away from claim and limited and scope; Can make many modifications, variation or equivalence, but all will fall within the protection domain of the utility model.
