Extended turntable of manual valve

Abstract

The invention discloses an extended turntable of a manual valve, which belongs to the technical field of manual valves and is characterized in that a handle I is arranged at the end of an operating rod of the valve, and a positioning connecting sleeve is welded on the handle I; sliding grooves and positioning grooves are arranged on the inner wall of the positioning connecting sleeve; guide strips and positioning blocks are arranged at the lower end of an extension sleeve; a lock rod is sleeved in the extension sleeve; two handles II are hinged to the upper end of the extension sleeve, and a pull rod is hinged between the inner ends of the handles II and the upper end of the lock rod; and the inner ends of the two handles II are provided with opposite through holes and are provided with lock pins. According to the extended turntable of the manual valve provided by the invention, the separable extended turntable is adopted, so that the space is not occupied, and the operation of the original handle I and the maintenance of a valve body are facilitated; and a locking structure composed of the lock rod, a positioning block and the like ensures the reliability of the extended turntable, the locking structure is controlled by the handle II at the upper end, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of manual valves, in particular to a manual valve extension turntable. Background technique [0002] A valve is a component used to control fluid in a pipeline transportation system, to change the direction of the fluid or to cut off the fluid. When the existing manual valve is in use, the valve core is gradually lifted by turning the turntable to realize the conduction of the pipeline. In the production process system of factories and mines, a very small number of valves on some medium transmission pipelines such as steam (gas) and water are installed in the air below the operating platform due to process requirements or other reasons. The operating frequency of these valves is low, and generally manual valve. Because the valve is under the operating platform, the turntable needs to be extended. [0003] A Chinese patent discloses a manual valve (CN204901028U) capable of extending the operating distance,...

AI Technical Summary

Problems solved by technology

[0004] The problem in the above technology is that it raises the manual handle by welding the fixed claw and the transmission rod. Although this fixed design can facilitate operation at a higher position (operating platform), it is not conducive to operating the valve at a lower position. ;The fixed transmission rod and manual handle occupy the original space, which is not conducive to the regular maintenance of the valve
