A lockable regulating valve

Abstract

The invention relates to the field of flow adjusting valves, in particular to an adjusting valve with a lock. The adjusting valve comprises a cylindrical shell, a linkage opening-closing mechanism anda lock control mechanism, the linkage opening-closing mechanism comprises a plurality of opening-closing plates with the same shape and size, and the opening-closing plates are attached one another;the shell comprises an outer shell, an inner shell and a sealing cover plate, an annular accommodating groove is formed between the outer shell and the inner shell, and each opening-closing plate is fixedly connected with a rotating shaft used for controlling rotation of the opening-closing plate; and a linkage device is arranged between every two adjacent opening-closing plates, the linkage devices are used for making all the opening-closing plates complete synchronous rotation, and the lock control mechanism is arranged on one of the rotating shafts and is inlaid on the side wall of the outer shell. According to the adjusting valve with the lock, opening and closing of the valve are controlled through a key, using is convenient, both time and labor are saved, and meanwhile, the situationthat after the key is pulled out, unrelated personnel open the valve at will can further be prevented, so that the safety degree is enhanced.

Description

technical field [0001] The invention relates to the field of flow regulating valves, in particular to a regulating valve with a lock. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems. There are various types and specifications. Valves can be used to control air, water, steam, various corrosive media, The flow of various types of fluids such as mud, oil, liquid metal and radioactive media. [0003] The current valves are mostly turned on and off by rotating the threaded rod, which usually requires a lot of effort and is quite time-consuming and laborious to use.

Problems solved by technology

[0003] The current valves usually complete the on-off effect by rotating the threaded rod, which usually requires a lot of effort and is quite time-consuming and labor-intensive to use. At the same time, the current valves cannot avoid the occurrence of artificial malicious opening or closing, resulting in serious losses.
