High pressure valve assembly for fire extinguisher

Abstract

The invention discloses a high pressure valve assembly for a first extinguisher. The high pressure valve assembly comprises a valve body, a spring seat arranged at the bottom of the valve body, a gasket arranged at the joint of the valve body and the spring seat, a pressure handle arranged at the top of the valve body, a spring arranged inside the valve body and fixed on the spring seat, a valve rod assembly arranged on the spring and connected with the pressure handle, a water pipe assembly arranged on the right side of the valve body, a gas pipe joint arranged on the right side of the water pipe assembly, a spray-head arranged on the gas pipe joint, a pressurizer arranged on the water pipe assembly, and a pressure switch arranged at the top of the pressurizer, wherein the pressure handle and the pressure switch are provided with suspension loops; a connecting rod is connected between the two suspension loops; an extension spring is sleeved on the connecting rod. The high pressure valve assembly is novel in design, firm for connection, wide in fire extinguishing range, high in fire extinguishing efficiency and convenient to use.

Description

technical field [0001] The invention relates to a high-pressure valve assembly for a fire extinguisher. Background technique [0002] At present, fire extinguishers are widely used, and they are particularly important in production work. When a fire breaks out, fire extinguishers are one of the indispensable fire extinguishing tools. Because some existing fire extinguisher nozzles are relatively short, they need to be connected to a water pipe assembly. It is convenient to use, and the existing fire extinguishers cannot extinguish long-distance open flames due to the low pressure, so they cannot meet the rescue needs at special moments. At special moments, the present invention is particularly important, and it can be used as a general fire extinguisher In use, it can be connected to the water pipe assembly for remote high-pressure fire extinguishing. It is very convenient to use, high in fire extinguishing efficiency, and very safe. Contents of the invention [0003] The...

It is convenient to use, and the existing fire extinguishers cannot extinguish long-distance open flames due to the low pressure, so they cannot meet the rescue needs at special moments. At special moments, the present invention is particularly important, and it can be used as a general fire extinguisher It can also be connected to the water pipe assembly for remote high-pressure fire extinguishing. It is very convenient to use, high in fire extinguishing efficiency, and very safe.
