Quick release stop valve

Abstract

The invention relates to a quick release stop valve, which can solve the problem that drying equipment is difficult to stop and maintain, has a long period and cannot be instantaneously switched from a working state to a hot standby state. The technical scheme is that: the stop valve comprises a valve body, a valve plug and a fixed pulley block; a first pool is arranged on the lower part of the valve body; the lower part of the first pool is provided with a coal gas inlet pipe of which the upper end extends into the valve body; the valve plug is arranged at the upper end of the coal gas inlet pipe; a pulley block bracket is arranged on the valve body; the fixed pulley block on the pulley block bracket is connected with the valve plug through a steel wire rope; a counterweight barrel is arranged at the other end of the steel wire rope; a first water supply pipe and an overflow pipe are respectively arranged on a side wall of the first pool; and a second water supply pipe is arranged on the valve body. The stop valve has a simple structure and a good using effect, and the problem that the drying equipment is difficult to maintain, has a long period and cannot be instantaneously switched from a working state to a hot standby state is effectively solved.

Description

technical field [0001] The invention relates to a fast release stop valve. Background technique [0002] With the vigorous development of the coal slime drying industry in recent years, it has provided a good development support for the country's energy development strategy, solved the problems of coal slime stacking and pollution in the coal washing industry, and exchanged a large amount of waste resources at a relatively small price. In recent years, the slime drying equipment industry has also entered a stage of vigorous development in terms of recycling and utilization. Since the drying equipment is a complex system composed of multiple electromechanical and mechanical equipment, it may be shut down for maintenance at any time. It is very difficult to quickly shut down and maintain equipment using large-scale thermal coal facilities such as fluidized fluidized furnaces and chain grate furnaces. Shutdown maintenance can be as short as three to five days, and as long as te...
