Problems solved by technology

[0002] The application for invention with the application number 00130747.9 discloses a rotary opening and closing floating spool stop valve, which consists of a valve body, spool, valve stem, bonnet, seal and valve stem control device, although it solves the water hammer phenomenon , it is easy to control the water output, but the handle cover is an overall cylindrical shape, has many consumables, lacks elasticity, is difficult to disassemble, the socket area with the handle is too large, and the manufacturing precision is high; moreover, the valve stem control device must be fixed through the fixing ring. Limits, many accessories, many threads, not only increase the assembly process, increase the manufacturing cost, but also reduce the stability of product quality
In addition, none of the existing faucets can solve the problem of anti-dripping, especially the problem of artificial dripping.

Abstract

The invention relates to the valve, especially valves with floating valve core in type of open and close by rotation. The valve is composed of the triple valve body, the floating valve core, the valve rod, the valve cap, the seal ring and the unit for controlling the valve rod. By taking full advantage of elasticity characteristics of the plastics, an erect claw is utilized to replace a cylinder.The circular bead is utilized to limit and lock the erect claw so as to reduce manufacturing accuracy needed as well as number of parts, material and cost. Since the steep fall structure of screw thread and the spring are used, the valve can return to closed position automatically when water quantity is low so as to solve the drip issue caused by not closing water faucet tightly or mild wear of seal ring. The stability of quality of the product is also raised.

Description

[technical field] [0001] The present invention relates to a valve, especially a valve stem control device for a floating valve core valve. [Background technique] [0002] The invention application with the application number 00130747.9 announced a rotary opening and closing floating spool stop valve, which is composed of a valve body, spool, valve stem, bonnet, seal and valve stem control device, although it solves the water hammer phenomenon , it is easy to control the water output, but the handle cover is an overall cylindrical shape, has many consumables, lacks elasticity, is difficult to disassemble, the socket area with the handle is too large, and the manufacturing precision is high; moreover, the valve stem control device must be fixed through the fixing ring. Limits, many accessories, and many threads not only increase the assembly process, increase manufacturing costs, but also reduce the stability of product quality. In addition, none of the existing faucets can s...
