DETAILED DESCRIPTION

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] Example:

[0030] like Figures 1 to 3 As shown, in order to solve the above problems, the present embodiment discloses an electric energy storage fire cluster control valve, including a valve body 10, a partition diaphragm 20, a puncture assembly 30 and an end cover 40, the valve body 10 is provided with a first flow channel 100, a second flow channel 101 and an installation cavity 102, the installation cavity 102 is arranged in the valve body 10, and one end of the installation cavity 102 passes through the top of the valve body 10, and the lower end of the installation cavity 102 is provided with an installation step 103;

[0031] The partition diaphragm 20 is installed on the installation step 103, and the installation cavity 102 is divided into an upper cavity 104 and a lower cavity 105. A locking member 21 is provided above the partition diaphragm 20, and the locking member 21 is threadedly connected to the installation cavity 102 for fixing the partition diaphragm 20. The first flow channel 100 is provided on one side of the valve body 10, and one end is communicated with the lower cavity 105. The second flow channel 101 is provided on the other side of the valve body 10, and one end is communicated with the upper cavity 104.

[0032] The puncturing assembly 30 is arranged in the upper cavity 104 and is slidably connected to the inner wall of the upper cavity 104 for puncturing the partition diaphragm 20. The end cover 40 is arranged on the top of the valve body 10 and is arranged in cooperation with the installation cavity 102 for closing the installation cavity 102. The end cover 40 is detachably connected to the valve body 10. A accommodating cavity 106 is provided between the end cover 40 and the puncturing assembly 30. A gas generating agent is provided in the accommodating cavity 106. An electric trigger wire 400 is provided on the end cover 40. One end of the electric trigger wire 400 is located in the accommodating cavity 106, and the other end passes through the end cover 40 and extends to the outside of the accommodating cavity 106. The electric trigger wire 400 is used to trigger the gas generating agent.

[0033] When in use, first install several electric energy storage fire cluster control valves described in the utility model in the fire extinguishing system for the energy storage battery cluster. When a fire occurs in the energy storage battery cluster, the fire extinguishing system triggers the gas generating agent to produce gas through the electric trigger line 400, so that the pressure in the accommodating chamber 106 increases, thereby pushing the puncture assembly 30 to move downward, thereby puncturing the partition membrane 20, so that the first flow channel 100 and the second flow channel 101 are connected, and the fire water can be sprayed out to complete the fire extinguishing. Compared with the traditional solenoid valve, the utility model no longer uses the electromagnetic structure, and has the advantages of simpler structure and lower cost, which solves the problem of complex valve structure and high valve cost of the solenoid valve in the fire extinguishing system currently used for the energy storage battery cluster.

[0034] The partition diaphragm 20 includes an annular shell and a diaphragm arranged on the annular shell. The diaphragm and the annular shell are integrally formed. The puncturing assembly 30 can puncture the diaphragm on the annular shell, thereby connecting the first flow channel 100 and the second flow channel 101.

[0035] In order to facilitate puncturing the partition diaphragm 20, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the puncturing assembly 30 includes a piston 300 and a pin 301. The pin 301 is arranged at the bottom of the piston 300, and one end is fixedly connected to the bottom of the piston 300. The piston 300 is slidably connected to the inner wall of the upper cavity 104.

[0036] When the gas generating agent is triggered to generate a large amount of gas, the piston 300 is pushed downward, so that the insertion needle 301 can pierce the isolation diaphragm 20 .

[0037] like Figures 2 to 3 As shown, in order to prevent the pin 301 from piercing the partition diaphragm 20 due to accidental touch, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a spring 302 is provided at the bottom of the piston 300, and the spring 302 is sleeved on the outside of the pin 301. One end of the spring 302 is connected to the bottom of the piston 300, and the other end is connected to the locking member 21.

[0038] The setting of the spring 302 can play the role of supporting the piston 300. When the gas generating agent is not triggered, the spring 302 supports the piston 300 to prevent the needle 301 from piercing the partition diaphragm 20; when the gas generating agent is triggered, the pressure in the accommodating chamber 106 increases, which can push the piston 300 to compress the spring 302, so that the needle 301 can pierce the partition diaphragm 20.

[0039] like Figure 5As shown, in order to facilitate the insertion pin 301 to pierce the partition diaphragm 20 and facilitate the installation of the partition diaphragm 20, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a hexagonal slot 200 is provided on the locking member 21, and the hexagonal slot 200 penetrates the locking member 21 from top to bottom, and one end of the pin 301 can pass through the hexagonal slot 200.

[0040] Preferably, an outer side of the locking member 21 is provided with an external thread, an inner side wall of the upper cavity 104 is provided with an internal thread matched with the external thread, and the locking member 21 is threadedly connected to the inner side wall of the upper cavity 104 .

[0041] When the piston 300 moves downward, one end of the pin 301 can pass through the hexagonal through slot 200 and puncture the partition diaphragm 20, and the locking member 21 is threadedly connected to the inner wall of the upper cavity 104, which can effectively fix the partition diaphragm.

[0042] like Figure 4 As shown, in order to facilitate the installation of the end cover 40 and improve the sealing of the accommodating chamber 106, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the lower end of the end cover 40 can be inserted into the upper cavity 104 to contact the top of the piston 300, the accommodating chamber 106 is arranged between the lower end of the end cover 40 and the top of the piston 300, and the end cover 40 is detachably connected to the top of the valve body 10 by bolts.

[0043] Preferably, a sealing ring 107 is provided on the inner wall of the upper cavity 104 to cooperate with the lower end of the end cover 40 . When the lower end of the end cover 40 is inserted into the upper cavity 104 , the lower end of the end cover 40 cooperates with the sealing ring 107 to form a seal.

[0044] The end cover 40 is detachably connected to the top of the valve body 10 by bolts, which can facilitate the installation of the end cover 40 . The lower end of the end cover 40 cooperates with the sealing ring 107 to form a seal, which can improve the sealing performance of the accommodating cavity 106 .

[0045] In another embodiment, the lower end of the end cover 40 can be inserted into the upper cavity 104 to contact the top of the piston 300, the accommodating cavity 106 is arranged between the lower end of the end cover 40 and the top of the piston 300, and the lower end of the end cover 40 is threadedly connected to the inner wall of the upper cavity 104.

[0046] Preferably, a sealing ring 107 is provided on the inner wall of the upper cavity 104 to cooperate with the lower end of the end cover 40. When the lower end of the end cover 40 is inserted into the upper cavity 104 and threadedly connected to the inner wall of the upper cavity 104, the lower end of the end cover 40 cooperates with the sealing ring 107 to form a seal.

[0047] like Figure 3As shown, in order to facilitate the installation of the utility model, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a first interface 108 is provided at one end of the first flow channel 100, and a second interface 109 is provided at one end of the second flow channel 101. The first interface 108 and the second interface 109 are used for external pipelines.

[0048] The first interface 108 and the second interface 109 can be connected to an external pipeline and can be detachably connected to the pipeline. The first interface 108 and the second interface 109 can be connected to the pipeline through a nut. The first interface 108 and the second interface 109 can also be connected to a pipeline flange.

[0049] Working principle of this utility model:

[0050] When in use, a plurality of the electric energy storage fire cluster control valves described in the utility model are first installed in a fire extinguishing system for an energy storage battery cluster. When a fire occurs in the energy storage battery cluster, the fire extinguishing system triggers the gas generating agent to generate gas through the electric trigger line 400, so that the pressure in the accommodating cavity 106 increases, thereby pushing the puncture assembly 30 to move downward, thereby puncturing the partition membrane 20, so that the first flow channel 100 and the second flow channel 101 are connected, and the fire water can be sprayed out to complete the fire extinguishing.

[0051] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
