Problems solved by technology

[0004] When the above-mentioned ultra-fine dry powder fire extinguisher valve is installed on the fire extinguisher tank to form an ultra-fine dry powder fire extinguisher, the high-pressure fire extinguishing agent in the fire extinguisher tank will give an upward pressure to the valve core, which will further press the valve core against the channel in the valve. On the stepped surface, the user needs to overcome the pressure of the spring and the pressure generated by the high-pressure fire extinguishing agent at the same time to drive the valve core assembly to move downwards, so as to realize the powder discharge of the ultra-fine dry powder fire extinguisher, and during the fire extinguishing process, the user needs to always press down The pressure rod keeps overcoming the spring pressure and the pressure of the high-pressure fire extinguishing agent, so this type of fire extinguisher is not suitable for people with small hands

Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0043] See attached figure 1 And attached figure 2 , a fire extinguisher valve mainly includes a valve body 1, a valve core 2 and a locking cylinder 3.

[0044] See attached image 3 , The valve body 1 includes a lower valve body 11 and an upper valve body 12 . The top of the lower valve body 11 is provided with a counterbore, and the side wall of the lower valve body 11 is also provided with a side hole communicated with the counterbore and arranged horizontally. The upper valve body 12 is threadedly mounted on the top of the lower valve body 11 , and seals and covers the top opening of the counterbore in the lower valve body 11 . When the upper valve body 12 is installed on the lower valve body 11 to form the valve body 1 , the counterbore and the side hole are combined to form the control chamber 131 , the first flow channel 132 and the second flow ch...

Abstract

The invention discloses a fire extinguisher valve. The problem that a fire extinguisher valve at the present stage is not suitable for people with small hand strength is solved. According to the technical scheme, the fire extinguisher valve is characterized by comprising a valve body, a valve element and a locking air cylinder, wherein the valve element blocks a flow channel opening of the valve body; the locking air cylinder has a locking state and an unlocking state; when the locking air cylinder is in the locking state, a piston rod of the locking air cylinder abuts against the bottom of the valve element, and therefore the valve element keeps the state of blocking the flow channel opening; when the locking air cylinder is in the unlocking state, the piston rod of the locking air cylinder retracts, and therefore the valve element ascends under the action of a high-pressure fire extinguishing agent, and opening of the fire extinguisher valve is achieved; and the locking air cylindercan be switched into the unlocking state from the locking state by puncturing a sealing film, the opening manner is simple, and the fire extinguisher valve is suitable for being used by people with small hand strength.

Description

technical field [0001] The invention relates to a fire extinguisher, in particular to a fire extinguisher valve. Background technique [0002] A fire extinguisher is a portable fire extinguishing tool. Chemicals or fire extinguishing gas and solid are placed in the fire extinguisher to put out the fire. Fire extinguishers are one of the common fire prevention facilities. They are stored in public places or places where fires may occur. Different types of fire extinguishers are filled with different ingredients. They are specially designed for different types of fires. Fire extinguishers have various types, functions and use environments. different. At present, the mainstream fire extinguishers basically open the fire extinguisher by pressing the valve, so that the fire extinguishing substance (such as dry powder, special clean gas for fire extinguishing, etc.) in the fire extinguisher is ejected to realize its fire extinguishing function. [0003] The Chinese invention pa...
