Abstract
The utility model relates to a hard sealing ball valve which comprises a valve body, a valve cover, a valve rod, a valve core, a sealing element, a handle, filling material and a material pressing nut, wherein the valve cover is fixed to both sides of the valve body by double-screw bolts and nuts; the valve core and the sealing element which are matched with each other are respectively arranged in the valve body and the valve cover; a spring is arranged between the sealing element and the valve cover; one end of the valve rod is fixedly connected with the valve core, and the other end is connected with the handle; the filling material which is pressed by the material pressing nut is filled in the circumference of the valve rod. The utility model overcomes the defects of complicated seal structure and easy leakage of an ordinary hard sealing valve. The utility model has the advantages of simple and compact structure, tight seal, low cost and long service life.
Description
The utility model relates to a kind of hard seal ball valve.
The seal arrangement of ordinary ball valve, generally all be based on soft seal, generally these have flexible nonmetallic material and make sealing seat with teflon or rubber, by them spool is clamped, reach sealing, still, because these nonmetallic material can not be born high temperature or high pressure, thereby dwindled their using scope greatly, therefore just required hard seal ball valve to replace, to adapt to the Environmental Conditions of High Temperature High Pressure.And traditional hard seal ball valve, its structure is all comparatively complicated, and sealing surface is very not tight with cooperating of valve core chamber, therefore very easily leaks, and has a strong impact on working life.
The purpose of this utility model is the above-mentioned defective that overcomes prior art, thus provide a kind of simple in structure, compact, sealing is tight, the hard seal ball valve of long service life.
The utility model comprises valve body, valve gap, valve rod, spool, Sealing, handle, filler and binder nut, valve gap is fixed by stud and nut in the both sides of valve body, be respectively equipped with the spool and the Sealing that cooperatively interact in valve body and the valve gap, Sealing and valve cover chamber are provided with spring, one end and the spool of valve rod are affixed, the other end connects handle, around it filler is set in valve body, and filler is by binder nut press seal.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model comprises valve body 1, valve gap 2, valve rod 3, spool 4, Sealing 5, handle 6, filler 7 and binder nut 8, valve gap 2 is fixing by stud 10 and nut 11 in the both sides of valve body 1, be respectively equipped with the spool 4 and the Sealing 5 that cooperatively interact in valve body 1 and the valve gap 2,2 of Sealing 5 and valve gaps are provided with spring 9, spring 9 adopts butterfly spring, one end and the spool 4 of valve rod 3 are affixed, the other end connects handle 6, around it filler 7 is set in valve body 1, filler 7 is by gland nut 8 press seals.During rotatory handling 6, valve rod 3 drives spools 4 rotations under user mode, and Sealing 5 is close to spool 4 under the effect of spring 9, reach the purpose of hard sealing.
The utility model makes the sealing effectiveness of hard seal ball valve greatly strengthen tool by above specific design Have simple and compact for structure, sealing is tight, cost is low, the advantage of long service life.
