High pressure gas control device

Abstract

A high-pressure gas control device, comprising a gas storage chamber, a spray pipe, a water spray head, a handle, a joystick, a ventilation control part, a control pin, and a rotary handle, and the ventilation control part is located between the gas storage chamber and the spray pipe, And be provided with return device, blowing mouth; Install control pin, control handle on the described rear handle, one end of described control pin is equipped with rotating handle, and the other end is provided with positioning platform, turns rotating handle to open and close blowing outlet , to carry out the blowing operation, and the control handle can also be braked to stop the blowing operation. The beneficial effect of the present invention is that by operating the control handle, the gas storage chamber can be continuously filled with high-pressure gas and the multi-air channels can spray high-pressure gas instantly, effectively improving the spray pressure and spray range, and effectively controlling the stability of the high-speed air flow, and at the same time Play the role of security protection.

Description

technical field [0001] The invention relates to a hand-held fire extinguishing tool, in particular to a high-pressure gas control device. Background technique [0002] Knapsack pulse air pressure spray pistol usually consists of seven parts: injector combination, water delivery pipe, water inlet pipe, bucket combination, air outlet pipe, pressure gauge, and pressure reducing valve combination, which can be used for fire fighting operations. When in use, two hands are usually used to hold the front and rear handles of the injector combination respectively. When the machine is working, the control handle is hooked with fingers to realize spray fire extinguishing. The range of sprayed water mist directly determines the knapsack pulse air pressure spray pistol Fire extinguishing ability, the current common structure in the market is to directly connect the gas storage tank through the control handle to control the ejection of high-pressure gas. The spray range is not ideal, and...

Problems solved by technology

When in use, two hands are usually used to hold the front and rear handles of the injector combination respectively. When the machine is working, the control handle is hooked with fingers to realize spray fire extinguishing. The range of sprayed water mist directly determines the knapsack pulse air pressure spray pistol Fire extinguishing ability, the current common structure in the market is to directly connect the gas storage tank through the control handle to control the ejection of high-pressure gas. The spray range is not ideal, and as the gas in the gas storage tank decreases, the air pressure gradually decreases, resulting in unstable pressure and unstable spray range. Therefore, it is urgent to develop a sprayer that is easy to control, has a large cross-sectional area of ​​gas delivery, and high instantaneous spray pressure. , pressure stabilized injector combination
