Abstract
The utility model discloses a ball valve without a dead corner. The ball valve comprises a left valve body, a right valve body and a valve seat which is arranged inside the right valve body. A sealing gasket is arranged between the left valve body and the right valve body and is fixed through a butterfly nut and a stud. O-shaped rings are arranged between the valve seat and the left valve body and the valve seat and the right valve body, a ball body is arranged inside the valve seat, the valve seat is in seamless connection with the ball body, a through hole is formed in the ball body, and the diameter of the through hole is the same as the diameter of a through hole of the left valve body and the diameter of a through hole of the right valve body. The ball valve without the dead corner has the advantages that the structure is simple, the ball body and the valve seat are in seamless connection, the sizes of the through holes are the same, remaining fluid is avoided, the erosion and the influence of the fluid on the valve are also reduced, a positioning pin is arranged, the rotating range of a handle is prevented from being too large, abrasion is reduced, and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of without dead angle spherical valve.
Background technique
In system of flow ducts, gate valve, stop valve, these three kinds of valve applications of ball valve obtain at most, their shortcoming is also each has something to recommend him, but general ball valve, in use because matching gap is larger, sealing is good not, the situation that fluid is residual and leak easily occurs, to having certain influence in working life of valve body.
The model utility content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of without dead angle spherical valve.
To achieve these goals, the measure that the utility model is taked:
A kind of without dead angle spherical valve, comprise left valve barrel, right valve barrel and be located at the valve seat in right valve barrel, be provided with sealing gasket between described left valve barrel, right valve barrel and fix by wing nut, stud, be provided with O type circle between valve seat and left valve barrel, right valve barrel, be provided with spheroid and valve seat and spheroid seamless link in valve seat, be provided with through hole in spheroid, described through hole is identical with the diameter of the through hole of left valve barrel, right valve barrel;
Be provided with valve rod between described spheroid and handle, valve rod and handle are fixed by nut, on valve rod between handle and right valve barrel, cover has thin nut and back-up ring, right valve barrel to be provided with for limiting the locating stud of handle the sphere of activities, between described valve rod and right valve barrel, is provided with bearing gasket.
The beneficial effects of the utility model: the utility model is simple in structure, seamless link between spheroid and valve seat, and the size of through hole is identical, avoided the residual condition of fluid, also reduced erosion and the impact of fluid on valve, the setting of locating stud, avoided the rotatable handle scope excessive, reduce wearing and tearing, improved the working life of valve.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of without dead angle spherical valve, comprise left valve barrel 1, right valve barrel 2 and be located at the valve seat 3 in right valve barrel 2, described left valve barrel 1, be provided with sealing gasket 4 between right valve barrel 2 and pass through wing nut 5, stud 6 is fixing, valve seat 3 is located in right valve barrel 2, valve seat 3 and left valve barrel 1, be provided with O type circle 7 between right valve barrel 2, be provided with spheroid 8 and valve seat 3 and spheroid 8 seamless links in valve seat 3, be provided with through hole 9 in spheroid 8, described through hole 9 and left valve barrel 1, the diameter of the through hole of right valve barrel 2 is identical, this structure is guaranteed in valve seat without dead angle, the fluid smooth and easy noresidue of circulating.
Be provided with valve rod 11 between described spheroid 8 and handle 10, valve rod 11 is fixing by nut 12 with handle 10, on valve rod 11 between handle 10 and right valve barrel 2, cover has thin nut 13 and back-up ring 14, right valve barrel 2 is provided with the locating stud 15 for limiting the handle the sphere of activities, be provided with bearing gasket 16 between described valve rod 11 and right valve barrel 2, can reduce because of the damage of mechanical wear to parts, increase the service life.
Those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.
