Adjustable high-strength valve rod connecting seat

Abstract

The invention relates to the technical field of sealing devices, in particular to an adjustable high-strength valve rod connecting seat which comprises a bottom connecting disc and a top connecting rod. According to the adjustable high-strength valve rod connecting base, the connecting end of the top of the upper overturning supporting plate is controlled to ascend and descend through the internal thread adjusting ring, so that the mounting angle of the lateral supporting mechanism is changed, the telescopic length of the transverse telescopic assembling plate is controlled, the adjustable high-strength valve rod connecting base can be matched with valves of different specifications and sizes, and the application range is widened; a transverse telescopic assembling plate and a lower turnover supporting plate which are movably connected are arranged on a bottom connecting disc, an upper turnover supporting plate is arranged on the outer side of a top connecting rod, and the lower turnover supporting plate and the upper turnover supporting plate are connected to the outer side of a valve rod upper seat in a clamped mode to form an inclined supporting and adjusting mechanism. Therefore, the supporting force of the outer side of the valve rod upper seat is improved, and the compressive strength is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sealing devices, in particular to an adjustable high-strength valve stem connecting seat. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control the flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. The valve is a control component in the fluid conveying system, which has the functions of cut-off, regulation, diversion, prevention of backflow, voltage stabilization, diversion or overflow and pressure relief. Valves used in fluid control systems, from the simplest shut-off valve to various valves used in extremely complex automatic control systems, have a wide variety and specifications. [0003] Valves can be used to control the flow of various types of fluids such as air, water, steam, various...

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 adjustable high-strength valve stem connection seat is provided to solve the problem that the traditional valve stem upper seat structure is simple and fixed and cannot be adjusted, which leads to the use of valves The range is limited, and at the same time, it is simply supported by the middle connecting rod, resulting in low lateral compressive strength and low stability.
