Abstract
The utility model discloses a spherical stop valve, which is composed of a valve seat, a valve sleeve, a spherical valve core, valve rod, a sealing ring, and a valve cover. The sealing surface of the valve seat is a conical surface, the valve sleeve is arranged on the valve seat, and the valve sleeve and the valve seat are in threaded connection; the inside of the valve sleeve is provided with the valve cover, and the valve sleeve and the valve cover are in threaded connection; the lower end of the valve cover is provided with a central hole with threads, the upper end thereof is provided with a regulating plug, and the upper end and the regulating plug are in threaded connection; both ends of the valve rod are respectively connected with the spherical valve core and a lifting ball for the valve rod via threads; the sealing ring is connected with the spherical valve core into one body and is sheathed on the valve rod, and the sealing ring is clamped and fixed by the valve seat and the valve sleeve. The utility model has the advantages of good sealing property and high durability.
Description
The utility model relates to a kind of spherical stop valve.
At present, what common stop valve was taked is that the plane compresses sealing, and owing to spool rotates with becoming one after the spinning puccinia graminis erosion, the software part of valve plug and sealing surface of seat produce and rub, so easy to wear and be not closed completely.
The purpose of this utility model provides a kind of leakage-proof effectively, long-lived spherical stop valve.
For achieving the above object, the technical solution that the utility model adopts is: spherical stop valve of the present utility model, form by valve seat, valve pocket, spherical valve core, valve rod, seal ring, valve gap; Sealing surface of seat is a conical surface, and valve pocket is located on the valve seat, and by being threaded, is provided with the valve gap that is threaded in the valve pocket; Valve gap is provided with threaded central aperture, and valve rod promotes the lower end that ball is positioned at threaded central aperture, and its upper end is provided with the adjusting plug that is threaded; The valve rod two ends promote ball with spherical valve core and valve rod respectively and are threaded; Seal ring and spherical valve core are connected as a single entity, and are enclosed within on the valve rod, by valve seat and valve pocket fastening.
Owing to adopted spherical valve core, sealing surface of seat is a conical surface, so the utlity model has good airproof performance, durable advantage.
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing 1 is the structural representation of the spherical stop valve of the utility model embodiment 1-angie type,
Accompanying drawing 2 is structural representations of the spherical stop valve of the straight formula of the utility model embodiment 2-.
The spherical stop valve of accompanying drawing 1,2 illustrated embodiments is made up of valve seat 1, valve pocket 2, spherical valve core 3, valve rod 4, seal ring 5, valve gap 6; The sealing surface of valve seat 1 is a conical surface, and valve pocket 2 is located on the valve seat 1, and by being threaded, is provided with the valve gap 6 that is threaded in the valve pocket 2; Valve gap 6 is provided with threaded central aperture 9, and valve rod promotes the lower end that ball 7 is positioned at threaded central aperture 9, and its upper end is provided with the adjusting plug 8 that is threaded; Valve rod 4 two ends promote ball 7 with spherical valve core 3 and valve rod respectively and are threaded; Seal ring 5 is connected as a single entity with spherical valve core 3, and is enclosed within on the valve rod 4, by valve seat 1 and valve pocket 2 fastenings.Clockwise turn valve gap 6, its adjusted plug 8 presses down valve rod and promotes ball 7, and spherical valve core 3 is close to the young sealing surface of circle, and the water source cuts off; Counterclockwise turn valve gap 6, valve gap 6 drive valve rods lifting balls 7 and move upward, and spherical valve core 3 breaks away from the circular cone sealing surfaces, and the water source is connected.
