Abstract

The invention discloses a fire extinguisher valve structure. The fire extinguisher valve structure comprises a valve seat, a valve element, a spring, a fixed arm and a rotating arm, wherein a spraying channel is formed in the valve seat; the spring pushes the valve element to block the spraying channel and divides the spraying channel into a low-pressure channel communicating with a spraying opening and a high-pressure channel communicating with a steel cylinder; a piston sleeve with an opening in the bottom is arranged on the valve seat; a piston is movably arranged in the piston sleeve and connected with a connecting rod; the connecting rod penetrates out of the top of the piston sleeve and penetrates through a kidney-shaped hole in the rotating arm; limiting blocks are arranged on positions, located on the two sides of the rotating arm, the connecting rod; a cavity defined by the piston and the top of the piston sleeve is connected with a first channel communicated with the high-pressure channel and a second channel communicated with the external atmosphere; and the first channel and the second channel are provided with a first valve element part and a second valve element part respectively. The valve structure of the fire extinguisher can be held for spraying by hands and can also perform automatic spraying, large grip strength is not needed during automatic spraying, physical strength can be saved, and old people and children with small grip strength can also easily carry out spraying.

Description

Technical field [0001] The invention belongs to the technical field of fire extinguisher valve, in particular, a fire extinguisher valve structure, in particular a powerful fire extinguisher valve structure. Background technique [0002] The fire extinguisher is a portable fire extinguishing tool. The fire extinguisher is placed in a fire extinguisher. It is used to save the fire. The fire extinguisher is one of the common fire protection facilities. The components stored in the public place or possible fires, different types of fire extinguishers Different, it is designed for different fires and must pay attention to avoiding anti-effect and danger. [0003] Existing fire extinguisher valves require a large grip, which makes the elderly and children have a certain obstacle when using fire extinguishers, and even if it can be used normally, the use of long-term pressing can cause the user to be exhausted. Inventive content [0004] The present invention provides a fire extinguis...
