Assembling mechanism with valve rod easy to disassemble

Abstract

The invention relates to the technical field of valve assembly parts, in particular to an easy-to-disassemble valve rod assembly mechanism which comprises an external mounting cylinder and a bottom mounting body which are used for assembling a valve control mechanism. According to the valve rod assembling mechanism easy to disassemble, the movable locking block and the adjusting rod are arranged in the lateral control rod, the setting angle of the movable locking block is changed through threaded stretching and retracting of the adjusting rod, so that the external mounting cylinder is convenient to assemble and disassemble, operation is easy and convenient, and the structure is stable and firm; the whole device is composed of the external installation cylinder, the bottom assembly disc, the internal installation shaft pipe and the lateral control rods, the split type structural layout is adopted, the device can adapt to various external installation cylinders by replacing the lateral control rods of different specifications according to needs, and the application range is very wide.

Description

technical field [0001] The invention relates to the technical field of valve fittings, in particular to a valve stem fitting mechanism with an easily detachable type. Background technique [0002] The gate valve is an opening and closing gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate plate, and the sealing surface is usually welded with metal material to increase the wear resistance. According to the different gates, gate valves are divided into rigid gate valves and elastic gate valves. [0003] The opening and closing part of the gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfa...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved valve stem assembly mechanism with easy disassembly is provided, which solves the problem that the upper seat of the valve stem is mostly one-piece fixed structure and cannot freely adjust the external valve stem as required. structure, so as to improve its scope of application, and because it cannot be disassembled, once it is partially damaged, it can only be discarded and replaced as a whole, and the cost of later maintenance and use is very high.
