Container valve capable of being opened repeatedly

By designing a reusable container valve, utilizing a pressure relief channel with piston and elastic components and electromagnet control, the container valve can be opened and closed multiple times and the extinguishing agent dosage can be precisely controlled. This solves the problem of single-use discharge of traditional container valves and improves the efficiency and safety of extinguishing agent use.

AI Technical Summary

Technical Problem

Traditional container valves have a one-time, irreversible opening mechanism, which causes the extinguishing agent to continue to be sprayed even after a small, easily controllable fire, resulting in waste and environmental impact, and limiting their applicability for precise control of the amount of extinguishing agent used.

Method used

Design a reusable container valve. Through the cooperation of a piston and an elastic element, the valve can be opened and closed using a pressure relief channel and a control device. Combined with an electromagnet to control the opening and closing of the pressure relief channel, multiple opening and closing and precise control of the extinguishing agent dosage can be achieved.

Benefits of technology

It enables multiple opening and closing of the container valve, reducing extinguishing agent waste and improving the efficiency and safety of extinguishing agent use, making it suitable for small-scale, easily controllable fires.

Abstract

The invention relates to a container valve capable of being opened repeatedly, and relates to the field of container valves. The valve comprises a valve body, an inner cavity is formed in the valve body, an air inlet and an air outlet are formed in the valve body, the air inlet and the air outlet are communicated through the inner cavity, a piston is arranged in the inner cavity in a sliding mode, and the piston moves to control on-off of the air inlet and the air outlet; a pressure cavity is defined between the piston and the inner wall of the inner cavity, an elastic piece is arranged in the inner cavity and used for pushing the piston to tend to separate the air inlet and the air outlet, and a pressure balance channel used for communicating the pressure cavity with the air inlet is formed in the piston. A pressure relief channel is arranged on the pressure cavity in a communicating mode, the pressure relief channel is used for rapidly relieving pressure of the pressure cavity, and a control device used for controlling the pressure relief channel to be opened and closed is arranged in the pressure relief channel. Repeated opening and closing of the container valve can be achieved, and the problem that the fire extinguishing agent is wasted due to one-time release of the fire extinguishing agent in the steel cylinder is solved.
