Abstract
The utility model relates to a ball valve structure, in particular to a seal abrasion self-compensation-type ball valve structure. The seal abrasion self-compensation-type ball valve structure comprises a valve body, a valve seat, a valve cover, a valve rod and a ball body. The ball body is located inside the valve body. The valve rod is fixed at the upper end of the ball body. The valve cover is fixed at the upper end of the valve rod. The valve seat is placed between the inner side of the valve body and the ball body. The valve body is of an I-shaped structure. Preferably, in order to save money, when the ball body or the valve rod needs replacing after being damaged, the ball body is detachably connected with the valve rod; and preferably, sealing packing is placed on the connection position of the lower end of the valve cover, the valve rod and the valve body. The valve body is specially designed to be I-shaped so as to ensure that sealing of the valve sear has a self-compensation function, can achieve a very good valve seat abrasion compensation function and prolongs service life of the ball valve.
Description
Technical field
The utility model relates to a kind of ball-valve structure, especially a kind of sealing wear self-compensating formula ball-valve structure.
Background technique
Ball valve is mainly used to block and the ducted medium of conducting, because its circulation area of ball valve unlatching back is consistent with the endoporus of pipeline, so resistance is very little, the essentially no pressure loss, so be widely used in oil, chemical industry, medical treatment, metallurgy, mine, the many fields of food etc.If cooperate with the adjustment type final controlling element, can also carry out the adjusting of flow, pressure to ducted medium.The material of the valve seat of present existing ball valve is polytetrafluoroethylene (PTFE), valve seat is that face contacts with face with spheroid, after using the unlatching closure repeatedly, can cause having the valve seat pressurized wearing and tearing repeatedly of sealing function, and then can cause the leakage of valve, cause the life-span of valve shorter.
The model utility content
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of can prevent the valve seat sealing wear self-compensating formula ball-valve structure of wearing and tearing too early.
For achieving the above object, the technical solution adopted in the utility model is: sealing wear self-compensating formula ball-valve structure comprises valve body, valve seat, valve gap, valve rod and spheroid.Spheroid is in the inside of valve body, and fixedly there is valve rod the upper end of spheroid.Valve gap is fixed on the upper end of valve rod.Be provided with valve seat between valve inner and spheroid, described valve body is worker's type or H type structure or H type structure.
Preferably, in spheroid or the replacing of valve rod damage needs, can reduce expenses for convenience, described spheroid and valve rod are to removably connect.
Preferably, be provided with stuffing box packing in the joint of lower end, valve rod and the valve body of valve gap.
Preferably, described valve seat has plastoelastic deformation for a long time.
Preferably, described valve seat enters four jiaos of worker's type structure.
The utility model has adopted worker's type design of valve body uniqueness, makes the sealing of valve seat have automatic compensation function, can reach the effect of the good compensation prooving of valve seat, has prolonged the life-span of ball valve.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Embodiment:
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Give the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1,
As depicted in figs. 1 and 2: sealing wear self-compensating formula ball-valve structure comprises valve body 1, valve seat 2, valve gap 3, valve rod 4 and spheroid 5.Spheroid 5 is in the inside of valve body 1, and fixedly there is valve rod 4 upper end of spheroid 5.Valve gap 3 is fixed on the upper end of valve rod 4.Between valve body 1 inside and spheroid 5, be provided with the valve seat 2 that seals.Described valve body 1 is worker's type structure.
For convenience spheroid 5 or valve rod 4 damage need to change in, can reduce expenses, described spheroid 5 is to removably connect with valve rod 4.
Joint at lower end, valve rod 4 and the valve body 1 of valve gap 3 is provided with stuffing box packing 6, to guarantee the top seal of valve, makes that the overall sealing performance of valve is better, and the stuffing box packing material is PTFE, and elasticity is fine, has good sealability.
In above-described embodiment, described valve body 1 also can be set to H type structure, and in like manner, compression valve seat 2 enters four jiaos of H type structure.
More than be the description to the utility model embodiment, by the above-mentioned explanation to the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
