Description

Technical Field

[0001] The utility model belongs to the technical field of fire extinguishing valves, and in particular relates to a fire extinguishing valve thread plug nozzle of a lithium battery energy storage module. Background Art

[0002] Lithium batteries have the advantages of large specific capacity, high operating voltage, long cycle life, small size and light weight. They are used in many scenarios. Lithium batteries can store energy and use the stored energy effectively when needed, thereby reducing energy loss. During the use of lithium battery energy storage modules, when a fire occurs in the lithium battery energy storage module, the lithium battery energy storage module is generally extinguished through a fire extinguishing valve, and the wire plug nozzle is an important component of the fire extinguishing valve, which is mainly used to spray the fire extinguishing agent inside the fire extinguishing valve to extinguish the lithium battery energy storage module.

[0003] However, when the existing fire extinguishing valve plug nozzle is actually used, the fire extinguishing agent is generally guided to be sprayed out by the nozzle hole core. However, the distance between the nozzle hole core and the nozzle hole in the existing fire extinguishing valve plug nozzle is relatively long, which makes it easy for the fire extinguishing agent to remain when it is sprayed out, increases the loss of the fire extinguishing agent, makes the fire extinguishing agent spraying efficiency low, and affects the practicability of the nozzle.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Through the setting of the nozzle assembly, the problem that the distance between the existing nozzle hole core and the nozzle hole is long, which leads to the easy residue of the fire extinguishing agent when it is sprayed out, can be solved, thereby reducing the loss of the fire extinguishing agent, enhancing the spraying efficiency of the fire extinguishing agent, thereby saving the fire extinguishing cost and improving the practicality of the nozzle.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-Figure 3 A lithium battery energy storage module fire extinguishing valve thread plug nozzle shown in the figure includes a valve body connecting seat 1, a nozzle assembly 2 is installed on the valve body connecting seat 1, the nozzle assembly 2 includes a connecting seat 21 installed on the valve body connecting seat 1 and a nozzle shell 22 fixed at one end of the connecting seat 21, a mounting cavity 23 is provided in the nozzle shell 22, a nozzle 24 is installed in the mounting cavity 23, nozzle holes 26 are provided on the valve body connecting seat 1 and the connecting seat 21, and a nozzle hole core 25 matching the nozzle hole 26 is provided at one end of the nozzle 24; a guide cavity 27 is also provided on the side of the mounting cavity 23 adjacent to the nozzle 24, the guide cavity 27 is connected with the nozzle hole core 25 and the nozzle hole 26, and the guide cavity 27 is conical.

[0024] As can be seen from the above, when in use, the valve body connecting seat 1 and the fire extinguishing valve are first screwed and fixed, so that the nozzle hole 26 on the valve body connecting seat 1 can maintain the normal circulation of the fire extinguishing agent, and the nozzle hole core 25 is kept horizontal and close to the nozzle hole 26 on the connecting seat 21 under the action of the nozzle 24, and the nozzle hole 26 on the connecting seat 21 guides the fire extinguishing agent to the inside of the guide cavity 27, so that the guide cavity 27 forms a short collection chamber, which can guide and store the fire extinguishing agent, thereby accurately guiding the fire extinguishing agent to the nozzle hole core 25 for spraying onto the lithium battery, which can solve the problem that the distance between the existing nozzle hole core 25 and the nozzle hole 26 is long, thereby causing the fire extinguishing agent to easily remain when spraying, reduce the loss of fire extinguishing agent, enhance the efficiency of fire extinguishing agent spraying, and thus improve the practicality of the nozzle.

[0025] Furthermore, a sealing cavity is provided on one side of the nozzle shell 22 adjacent to the connecting seat 21, and a sealing ring 28 is sleeved in the sealing cavity; based on this, the arrangement of the sealing ring 28 makes the whole have better sealing performance.

[0026] In addition, refer to Figure 2-Figure 4 As shown, a stabilizing component 3 is provided on the nozzle 24, and the stabilizing component 3 includes a positioning column 31 fixed at one end of the nozzle 24 and a positioning cavity 32 opened on the side of the installation cavity 23 adjacent to the guide cavity 27, and a connecting column 33 matched with the positioning column 31 is fixed in the positioning cavity 32; an insertion rod 34 is also fixed at one end of the positioning column 31, and a slot 35 for inserting the insertion rod 34 is opened at one end of the connecting column 33; a sealing ring 36 is also fixedly sleeved on the outside of the positioning column 31, and a limiting groove for clamping the sealing ring 36 is opened in the positioning cavity 32.

[0027] Through the above technical solution:

[0028] When in use, by fixing the connecting column 33 deep inside the positioning cavity 32, the nozzle 24 is pushed along the inside of the installation cavity 23, so that the positioning column 31 moves synchronously along the installation cavity 23, and when the insertion rod 34 conflicts with the inner wall of the installation cavity 23, the nozzle 24 cannot push and rotate the nozzle 24, and then the insertion rod 34 is inserted into the positioning cavity 32. As the nozzle 24 continues to move, the insertion rod 34 and the slot 35 are clamped and fixed, and the positioning column 31 and the connecting column 33 are stably fixed, so that the nozzle 24 is located in the installation cavity 23 for precise positioning, which is conducive to the stable installation of the nozzle 24, can reduce the loosening of the nozzle 24, enhance the efficiency of the fire extinguishing agent spraying, and improve the practicality of the nozzle.
