Abstract
The utility model discloses a hard-to-leak ball valve, which comprises a ball valve body and a ball body. A seal ring is arranged between the ball valve body and the ball body; the seal ring is made of polytetrafluoroethylene; the ball body is fixedly connected with a ball valve pull rod; the ball valve pull rod is fixedly connected with a pull rod handle; a gland is sheathed outside the ball valve pull rod; a through hole is formed in the ball body; the middle of the bottom face of the through hole is higher than both ends of the through hole. The hard-to-leak ball valve disclosed by the utility model has the beneficial effects that the structural practicability is high, the operation is convenient, and the service time is long. Compared with other ball valves, the hard-to-leak ball valve has the advantages that the trouble brought by the fact that parts need to be frequently replaced due to the fact that the seal ring is abraded is reduced, the working time of the handle is prolonged, the operation inconvenience brought by the abrasion of the handle is reduced, the production efficiency is increased to a certain degree, and the enterprise revenue is also improved. The ball valve disclosed by the utility model is hard to leak.
Description
Technical field
The utility model relates to a kind of valve technology, particularly a kind of ball valve.
Background technique
Common general ball valve in the market, after using a period of time, all can occur that sealing effect is bad, the phenomenon of fluid leaks, and service time grown handle position can be because mill too smooth and easy sliding hand, the reason that occurs these problems is mainly because the problem of the sealing ring material using, and the impact of valve body structure aspect causes.
Model utility content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of ball valve is provided.
To achieve these goals, the measure that the utility model is taked:
Be difficult for the ball valve of revealing, comprise ball valve body, spheroid, between ball valve body and spheroid, be provided with seal ring, described seal ring is teflon, spheroid is fixedly connected with ball valve pull bar, and ball valve pull bar is fixedly connected with pull bar handle, and the outer surface cover of ball valve pull bar has gland, spheroid is provided with through hole, and higher than two ends in the middle of the bottom surface of through hole;
The top of described ball valve pull bar is provided with Stem Mut, and pull bar handle is provided with positioning lock, and the outer surface cover of pull bar handle has taper knob, between Stem Mut and positioning lock, is provided with spring washer;
Between described gland and ball valve body, be provided with stuffing, stuffing be provided with below thrust washer;
On described taper knob, be fixedly installed antiskid groove.
The beneficial effects of the utility model: structure practicability is good, easy to operate, service time is long, other ball valves have reduced because ring wear needs the frequent trouble of bringing of changing parts relatively, also make the operating time of handle extend, reduced the operation inconvenience that the wearing and tearing because of handle bring, improved to a certain extent manufacturing efficiency, also improved the performance of enterprises, be difficult for revealing.Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
Fig. 2 is plan view of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, be difficult for the ball valve of revealing, comprise ball valve body 1, spheroid 2, between ball valve body 1 and spheroid 2, be provided with seal ring 3, described seal ring 3 is teflon, and spheroid 2 is fixedly connected with ball valve pull bar 4, ball valve pull bar 4 is fixedly connected with pull bar handle 5, the outer surface cover of ball valve pull bar 4 has gland 6, and polytetrafluoroethylmaterial material is wear-resisting, can reduce because the inconvenience that the wearing and tearing of seal ring 3 bring to production.Spheroid is provided with through hole, and higher than two ends in the middle of the bottom surface of through hole, is not easy ponding like this in through hole.
The top of described ball valve pull bar 4 is provided with Stem Mut 7, and pull bar handle 5 is provided with positioning lock 8, and the outer surface cover of pull bar handle 5 has taper knob 10, between Stem Mut 7 and positioning lock 8, is provided with spring washer 9.
Between described gland 6 and ball valve body 1, be provided with stuffing 11, stuffing 11 be provided with below thrust washer 12.On described taper knob 10, be fixedly installed antiskid groove 13.
Use of the present utility modelly, only seal ring 3 need be put between ball valve body 1 and spheroid 2, the purpose of this utility model can be realized in the outside that the taper knob with antiskid groove 13 10 is enclosed within to pull bar handle 5.
