Fire-fighting valve

Abstract

The invention relates to a fire-fighting valve. The fire-fighting valve comprises a valve body, wherein a cavity body is formed in the valve body, a liquid outlet pipeline is arranged at one side of the valve body, a liquid inlet pipeline is arranged at the other side of the valve body, a switch mechanism is arranged on the valve body, and a mist spray mechanism is arranged on the lower part of the valve body; the switch mechanism comprises a location barrel, the location barrel is installed on the valve body, a cyclophon sleeves into the location barrel, a valve element is arranged at the lower end of the cyclophon, sealing layers made from rubber are arranged at the two sides of the valve element separately, an open hole is formed in the middle part of the valve element, an insertion-extraction core is installed in the middle part of the valve element, the insertion-extraction core seals the open hole, an insertion-extraction rod is installed at an axial position of the cyclophon, the lower end of the insertion-extraction rod is installed at the top of the insertion-extraction core, an insertion-extraction disc is arranged at the upper end of the location barrel, a fixed ring isarranged at the upper end of the insertion-extraction rod, and the fixed ring is installed on the insertion-extraction disc; and the valve element is installed at a position of the cavity body. The fire-fighting valve facilitates to realize mist spray, and facilitates to flexibly adjust the inclination of a mist spray shell, so that the efficiency of mist spray treatment is greatly increased.

Description

technical field [0001] The invention relates to a valve, in particular to a fire-fighting valve. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. 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, from the simplest globe valves to various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, sta...

AI Technical Summary

Problems solved by technology

The existing fire valve is an important accessory for the control of industrial and construction pipelines; the fire valve does not have the function of spraying water while spraying, and it is inconvenient to control the valve core in the fire valve, and the switch control efficiency is low
