Control structure of fire-fighting extinguisher valve

Abstract

The invention relates to the technical field of fire-fighting equipment, and discloses a control structure of a fire-fighting extinguisher valve. The control structure comprises a valve sleeve, a valve element and a valve rod, wherein the valve rod is movably sleeved with the valve element, an upper pressing plate and a lower pressing plate are fixedly arranged at the positions, located on the upper side and the lower side of the valve element, of the outer part of the valve rod respectively, the upper pressing plate is used for driving the valve element to move downwards, the lower pressing plate is used for driving the valve element to move upwards, a rubber ring I is fixedly connected to the position, located on the periphery of the valve rod, of the bottom end of the valve element, anda rubber ring II which is arranged corresponding to the rubber ring I is arranged at the top end of the lower pressing plate. According to the control structure, the valve rod is movably sleeved withthe valve element, and the upper pressing plate and the lower pressing plate which are positioned on the upper side and the lower side of the valve element respectively are used for controlling the valve rod to operate the valve element to move up and down, so that the upper side air pressure and the lower side air pressure of the valve element are balanced through separation of the lower pressing plate and the valve element, while the sealing performance is guaranteed, the pressing resistance of a pressing handle due to the inner and outer pressure difference of a bottle is greatly reduced,then, a sealing structure of the valve element is opened by manually pressing the valve rod, and then the effect of being more labor-saving is achieved.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a valve control structure of a fire extinguisher. Background technique [0002] Fire extinguisher is a kind of portable fire extinguishing tool. According to the fire extinguishing agent filled in the fire extinguisher, it can be divided into foam, dry powder, carbon dioxide, water and other fire extinguishers. The types of fire extinguishers are different, and the valves of the fire extinguisher bottle are different. For gas fire extinguishers such as carbon dioxide, the carbon dioxide gas is compressed and stored in the bottle. When using it, the handle is pressed, and the gas in the bottle is vaporized and released. During daily storage, the sealing of the bottle mouth of the fire extinguisher is high. Traditional When the valve sealing structure is used in a low-temperature environment below -20 degrees Celsius, there will be a problem of fire extinguisher lea...
