The beneficial effects of the utility model are that, through the sealed and clamp plate of the sealed face of disk seat and disk seat boss and the sealed of valve body, disk seat, guaranteed the reliability of sealing between disk seat and the valve body under high-pressure medium pressure.
Description
Technical Field
The utility model relates to a ball valve, especially a top-mounted type ball valve sealed firmly.
Background
The upper-mounted hard seal ball valve is generally applied due to the advantages of simple structure, convenience in opening and closing, convenience in maintenance, long service life, bidirectional sealing, zero leakage and the like. The ball and the valve seat are arranged in the opening of the upper end face of the valve body, and hard sealing is adopted between the ball and the valve seat, so that the ball valve has the characteristics of high temperature resistance, high pressure resistance and the like. However, the inlet and outlet valve seats generally adopt a floating valve seat structure, and the outlet valve seat is pushed to move under the pressure of a high-pressure medium, so that the sealing performance between the ball body and the valve seat is influenced, and meanwhile, the sealing performance between the valve body and the valve seat is also influenced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the prior art problem, the utility model provides a top-mounted hard seal ball valve.
The technical scheme of the utility model, a hard sealed ball valve of upper assembling formula, including valve body, disk seat, be equipped with the valve body boss on the valve body, be equipped with the disk seat sealing face on the disk seat, be equipped with spring I, spring II, steel ball, clamp plate between valve body boss and the disk seat sealing face, the clamp plate has the leakproofness.
Preferably, spring I locates between two clamp plates, and the clamp plate both ends are equipped with the steel ball, and II one ends of spring and steel ball butt.
The beneficial effects of the utility model are that, through the sealed and clamp plate of the sealed face of disk seat and disk seat boss and the sealed of valve body, disk seat, guaranteed the reliability of sealing between disk seat and the valve body under high-pressure medium pressure.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is an enlarged view of portion A of FIG. 1;
fig. 3 is a schematic view of a valve seat.
In the figure: 1. a valve body; 2. a valve seat; 3. a valve body boss; 4. pressing a plate; 5. springs I, 6. steel balls; 7. a spring II; 8. a valve seat sealing surface.
Detailed Description
As shown in the figure, a top-mounted hard sealing ball valve comprises a valve body 1 and a valve seat 2, wherein a valve body boss 3 is arranged on the valve body 1, a valve seat sealing surface 8 is arranged on the valve seat 2, a spring I5, a spring II 7, a steel ball 6 and a pressing plate 4 are arranged between the valve body boss 3 and the valve seat sealing surface 2, the pressing plate 4 has sealing performance, the spring I5 is arranged between the two pressing plates 4, the steel ball 6 is arranged at two ends of each pressing plate 4, and one end of the spring II 7 is abutted to the steel ball.
Through the sealed of the sealed face 8 of disk seat and the formation of disk seat boss 3 to and under high pressure medium pressure, spring II 7 extrudees steel ball 6, and 6 rethread springs I5 extrusion clamp plates 4 of steel ball make the sealed vice that clamp plates 4 and valve body 1, 2 butts of disk seat formed, ensured the reliability sealed between disk seat 2 and the valve body 1.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
