Problems solved by technology

[0002] At present, the container valves of the fire extinguishing agent liquid storage bottles in the existing fire extinguishing systems on the market are all manually and electrically activated, and some can be activated by high-pressure pneumatics, but they all need to be equipped with nitrogen starting bottles separately. In the fire extinguishing system, the container valve of each liquid storage bottle must be connected with a nitroge

Abstract

The invention discloses a multifunctional container valve, comprising: a main valve body, a main valve core assembly, a drive housing, etc., the main valve body is provided with a collecting pipe joint communicating with the valve cavity; the main valve core assembly is blocked in the valve Between the cavity and the lower end interface of the main valve body, the main valve core assembly is provided with an air guide hole leading to the upper end interface of the main valve body, and a diaphragm is arranged at the port of the air guide hole; the drive housing communicates with the upper end interface, and the drive housing A first piston is slidingly installed in the driving chamber of the body, and a puncture needle facing the diaphragm is connected to the first piston. The first piston divides its interior into an upper half chamber and a lower half chamber. Pneumatic inlet fittings and pneumatic outlet fittings communicating with the upper and lower chambers. The multifunctional container valve of the present invention is suitable for fire extinguishing systems with multiple groups of liquid storage bottles. Automatic start, high start-up efficiency, safe and convenient operation.

Description

technical field [0001] The invention relates to the field of fire fighting equipment, in particular to a multifunctional container valve. Background technique [0002] At present, the container valves of the fire extinguishing agent liquid storage bottles in the existing fire extinguishing systems on the market are manually and electrically activated, and some can be activated by high-pressure pneumatics, but they all need to be equipped with nitrogen starting bottles separately. In a fire extinguishing system, the container valve of each liquid storage bottle must be connected with a nitrogen priming bottle. These nitrogen priming bottles take up a lot of space, are expensive, and often lead to system instability and are difficult to put into use. When a situation occurs, due to various reasons, the existing fire extinguishing system with multiple liquid storage bottles often cannot guarantee that all liquid storage bottles can be started normally. The number of bottles is...
