[0002] With the widespread use of industrial and mining vehicles in production and transportation, the risk of fire is also on the rise. In order to effectively respond to and prevent fire risks, industrial and mining vehicle fire extinguishing devices have become indispensable safety equipment. However, the fixed directional valve body design used in the common industrial and mining vehicle fire extinguishing devices on the market has limitations in production and installation.

[0003] First, in terms of structural design, the fixed directional valve body has a relatively single function and is difficult to adapt to the diverse demands of different vehicle models and working conditions for the valve body, which may make customization of the fire extinguishing system more difficult.

[0004] Secondly, from the perspective of installation and positioning, in order to ensure that the fixed-direction valve body meets customer needs, it is necessary to accurately calculate and adjust the relative position of the valve body and the fire extinguisher tank body, which not only increases the production precision requirements, but also increases the workload during the installation process.

[0005] Finally, in terms of durability, the fixed directional valve body is mainly made of copper chrome-plated material. In harsh environments such as industrial and mining, the valve body is easily corroded, which affects its service life.

[0006] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a movable valve body used in industrial and mining vehicle fire extinguishing devices. Utility Model Content

[0028] The lower valve body 3 includes a valve body 301, the top of the valve body 301 is arranged in a stepped shape, and a valve body rubber ring 1 3011 is embedded in the top surface, and a valve body rubber ring 2 3012 is embedded in the stepped surface, a valve body thread 1 3013 is arranged on the outside of the valve body 301, a venting device thread 3014 is arranged on the left interface of the valve body 301, and the venting device thread 3014 is connected to the venting device 303, a valve body thread 2 3015 is arranged on the outer wall of the lower part of the valve body 301, and a piston device 3016 is arranged in the valve body 301, and the piston device 3016 A piston diameter 30161 is arranged inside, a piston rubber ring 1 30162 is arranged on the lower outer wall of the piston device 3016, a piston rubber ring 2 30163 is arranged on the middle outer wall of the piston device 3016, a piston outer wall 30164 is arranged on the top of the piston device 3016, and a safety valve 302, a deflation device 303, a pressure feedback device 304, an inflation device 1 305, a drug pipeline interface 307 and an inflation device 2 308 are arranged on the valve body 301 in sequence, and a pressure gauge 306 is installed on the inflation device 1 305.

[0029] During assembly, the piston is assembled first. Make sure that the piston rubber ring 1 30162 and the piston rubber ring 2 30163 are respectively inserted into the appropriate positions of the piston 3016. Then, the processed piston outer wall 30164 is coated with silicone oil and placed inside the valve body 301, and the spring is placed on the top.

[0030] Next is the assembly of the valve body. Place the valve body rubber ring 1 3011 and the valve body rubber ring 2 3012 in the appropriate positions of the valve body 301. Then, insert the inner cavity 1014 of the movable valve cap into the upper part of the valve body 301, making sure that it presses the spring, and use the valve cap nut 2 to fasten the movable valve cap 101 to the valve body 301. In order, install the safety valve 302, the air release device 303, the pressure feedback device 304, the inflation device 305, the pressure gauge 306, the drug pipeline interface 307 and the inflation device 308 on the valve body 301, and make sure that each component is fastened and sealed.

[0031] Finally, assemble the movable valve bonnet. Place the valve bonnet seal ring 102 at the bottom of the valve bonnet thread 1011, and install the reducer interface 103 at the valve bonnet thread 1011 to ensure that the connection is tight. Then, tighten the reducer 103 and the inspection valve 104. Next, place the valve bonnet seal ring 105 at the bottom of the valve bonnet thread 1012, and place the diaphragm 106 on the upper part of the valve bonnet thread 1012, and tighten it with the pressure nut 107. Finally, install the emergency button 108 on the 3# valve bonnet thread 103 to ensure that the connection is tight.

[0032] In this embodiment, when in use, under normal use, the movable valve body of the industrial and mining vehicle fire extinguishing device of the utility model is in a pressure-maintaining state, and the agent bottle has been filled with agents. At this time, the movable valve cap 101 is fastened to the lower valve body 3 through the valve cap nut 2 to ensure the sealing of the entire valve body. The safety valve 302, the air release device 303, the pressure feedback device 304, the charging device 305, the pressure gauge 306, the agent pipeline interface 307 and the charging device 308 are all installed on the valve body 301 in sequence and are in a normal working state.

[0033] When a fire occurs in a mining vehicle, the operator quickly opens the inspection valve 104 or presses the emergency button 108. At this time, the pressure in the upper cavity space of the valve body quickly leaks from the inspection valve 104, causing an imbalance in the pressure inside the valve body. The piston 3016 is pushed upward by the pressure at the bottom of the valve body. This action causes the agent to be quickly released through the agent pipeline interface 307 to extinguish the fire.

[0034] At the same time, the pressure feedback device 304 monitors the pressure change in the valve body in real time to ensure the pressure stability during the fire extinguishing process. When the pressure is insufficient, the inflation device 1 305 and the inflation device 2 308 will replenish the pressure in time to ensure the fire extinguishing effect.

[0035] During the fire extinguishing process, if the device needs to be deflated, a wrench can be used to loosen the deflation device 303. In this way, the gas in the valve group of the medicine bottle will be directly discharged from the deflation port of the deflation device 303, and rapid deflation is achieved.

[0036] The movable valve body of the industrial and mining vehicle fire extinguishing device of the utility model is reasonably designed, compact in structure, and easy to operate. The rapid release of the agent and fire extinguishing are achieved through the up and down movement of the piston device 3016. At the same time, the sealed connection between the components ensures the pressure stability and safety during the fire extinguishing process. In addition, the utility model also has a deflation function, which facilitates the maintenance and care of the device.

[0037] In practical applications, the movable valve body of the industrial and mining vehicle fire extinguishing device of the utility model shows good fire extinguishing effect and stability. It not only improves the safety of industrial and mining vehicles, but also reduces the losses caused by fire. At the same time, its simple and practical design also enables operators to quickly master the use method and improve the fire extinguishing efficiency.

[0038] The movable valve body of the industrial and mining vehicle fire extinguishing device of the utility model is an efficient, safe and practical fire extinguishing device. It has a wide range of application prospects in the field of industrial and mining vehicle fire extinguishing and provides strong support for ensuring the safe operation of industrial and mining vehicles.
