Abstract
The utility model relates to a ball valve structure which comprises a valve body; the valve body is internally provided with a ball body; a valve rod is arranged at the upper part of the ball body; a valve cover is arranged at the valve rod above the valve body; a valve seat is arranged between the interior of the valve body and the ball body; and as the valve seat is designed to be concave, the automatic comprehension can be carried out when a sealing surface is worn. As the ball valve structure adopts the sealing design of the valve seat with the automatic compensation function, the wearing of a sealing ring is compensated very well by the ball valve structure, and the service life of the ball valve is prolonged.
Description
Technical field
The utility model relates to a kind of ball-valve structure, and especially relating to a kind ofly can increase the ball valve ball-valve structure in working life.
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 or the like.If cooperate, can also carry out flow to ducted medium, the adjusting of pressure with the adjustment type final controlling element.Because the material of valve seat is a polytetrafluoroethylene (PTFE), serviceability temperature is the highest can only to reach 150 degrees centigrade, causes seal ring or the like wearing and tearing too early.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of ball-valve structure that can prevent that seal ring from wearing and tearing too early.
The technical scheme in the invention for solving the technical problem is: a kind of ball-valve structure, comprise valve body, valve inner is provided with spheroid, and spheroid top is valve rod, valve rod place above valve body is provided with valve gap, and the position between valve inner and spheroid is provided with valve seat.
Valve seat has the design of spill, can compensate automatically during sealing surface wear.
In spheroid or the replacing of spheroid bar damage needs, can reduce expenses for convenience, described spheroid and spheroid bar removably connect.
The beneficial effects of the utility model are: adopted the valve base sealing design that has automatic compensation function, can reach the effect of good compensation sealing circle wearing and tearing, prolonged the life-span of ball valve.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged view at the utility model valve seat place.
Among the figure: 1, valve body 2, valve seat 3, valve gap 4, valve rod 5, spheroid
Embodiment
A kind of as depicted in figs. 1 and 2 ball-valve structure comprises valve body 1, and valve body 1 inside is provided with spheroid 5, and spheroid 5 tops are valve rods 4, and valve rod 4 places above valve body 1 are provided with valve gap 3, and the position between valve body 1 inside and spheroid 5 is provided with valve seat 2; Described spheroid 5 removably connects with valve rod 4.
The utility model valve seat 2 adopts PTFE to make through special process, have the plastoelastic deformation material is arranged for a long time, the PTFE material surface has outstanding self lubricity, and the surface that nearly all stickum all can not adhere to it valve rod that gets on to float is eliminated the wearing and tearing of thrust washer; Valve body 1 inner unique spill design makes ball valve sealing have automatic compensate for wear function.
Claims (2)
1. ball-valve structure, comprise valve body (1), valve body (1) inside is provided with spheroid (5), and spheroid (5) top is valve rod (4), valve rod (4) in valve body (1) top locates to be provided with valve gap (3), it is characterized in that: the position between valve body (1) inside and spheroid (5) is provided with valve seat (2).
