Description

Technical Field

[0001] This utility model relates to the field of automatic distribution device technology, and in particular to an automatic distribution device for high-efficiency gaseous fire extinguishing agent. Background Technology

[0002] The automatic distribution device is used to distribute high-efficiency gaseous fire extinguishing agents to areas of different sizes. The device consists of a first fire extinguishing agent cylinder, a second fire extinguishing agent cylinder, a first nitrogen cylinder, a second nitrogen cylinder, a first drive line, a second drive line, a first electric selector valve, a third drive line, a fourth drive line, a high-pressure hose, an external connecting pipe, a check valve assembly, and a solenoid valve. When using the automatic distribution device, the controller activates the solenoid valve on the first nitrogen cylinder, allowing gas to flow from the first nitrogen cylinder through the first drive line to the first electric selector valve. Simultaneously, the controller activates the first electric selector valve, allowing gas to flow through the second drive line. This also opens the solenoid valves on the first and second fire extinguishing agent cylinders, allowing gas to flow to the high-pressure hose. At the same time, the second electric selector valve... With the rotary valve closed, the gas flows from the external connector connected to the first electric selector valve to the larger fire zone, designated Fire Zone 1. The controller activates the solenoid valve on the second nitrogen cylinder, causing nitrogen to flow through the third drive line to the second electric selector valve. Simultaneously, the controller activates the second electric selector valve, causing nitrogen to flow through the fourth drive line to the second drive line. Since the second drive line has a first check valve, the controller also opens the solenoid valve on the second extinguishing agent cylinder, allowing the gas to flow to the high-pressure hose. Meanwhile, the first electric rotary valve remains closed, causing the gas to flow through the external connector connected to the second electric selector valve to the smaller fire zone, designated Fire Zone 1. This achieves automated distribution. The extinguishing agent cylinder contains the highly efficient gaseous extinguishing agent, heptachloropropane.

[0003] In their daily work, the inventors discovered that when using the automatic distribution device, the external connector needs to be connected to the external pipe in the fire zone. Usually, the external connector is connected to the external pipe by inserting the external pipe into the external connector and then using a screwing tool to tighten the clamp, thereby fixing the external connector to the external pipe. This can make the entire installation process quite troublesome. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in actual use, the external connector needs to be connected to the external pipe of the fire zone. Usually, the external connector and the external pipe are connected by inserting the external pipe into the external connector and then using a screwing tool to tighten the clamp to fix the external connector and the external pipe, which may make the whole installation process quite troublesome. Therefore, this utility model proposes an efficient automatic gas extinguishing agent distribution device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency automatic gas extinguishing agent distribution device, comprising a first nitrogen cylinder, a second nitrogen cylinder, a first extinguishing agent cylinder, and a second extinguishing agent cylinder. Solenoid valves are installed at the upper ends of the first nitrogen cylinder, the second nitrogen cylinder, the first extinguishing agent cylinder, and the second extinguishing agent cylinder. A first driving pipeline is provided at the upper end of the first nitrogen cylinder, and the first driving pipeline is connected to the solenoid valve at the upper end of the first nitrogen cylinder. A first electric selector valve is fixedly connected to the other end of the first driving pipeline. An external connector and a second driving pipeline are installed on the surface of the first electric selector valve. A convenient fixing component is provided on the arc surface of the external connector. The second driving pipeline is fixed to the solenoid valves on the first and second extinguishing agent cylinders. The upper end of the second extinguishing agent cylinder is provided with... A high-pressure hose is provided. A second electric selector valve is fixedly connected to the arc surface of the high-pressure hose. A third drive line is fixedly connected between the second electric selector valve and the solenoid valve on the second nitrogen cylinder. A fourth drive line is fixedly connected between the second electric selector valve and the second drive line. A first one-way valve is installed on the arc surface of the second drive line. A first input pipe is fixedly connected to the solenoid valve on the high-pressure hose and the second fire extinguishing agent cylinder. A second input pipe is fixedly connected to the solenoid valve on the high-pressure hose and the first fire extinguishing agent cylinder. The convenient fixing component includes an access end fixedly connected to the upper end of the external connector. A sliding end is slidably connected to the arc surface of the access end. An external pipe is fixedly connected to the upper end of the sliding end. A positioning block is slidably inserted into the arc surface of the access end. The positioning block is inserted into the sliding end.

[0006] The effect achieved by the above components is as follows: by setting up a convenient fixing component, when it is convenient to fix the outer pipe to the outer connector, the pulling mechanism makes the positioning block completely retract into the access end, so that the reset mechanism is compressed, and then the sliding end is dragged into the access end. When the pulling mechanism is released, the reset mechanism is reset, and the positioning block is inserted into the sliding end, thereby achieving the effect of conveniently fixing the outer pipe to the outer connector as much as possible.

[0007] Preferably, a spring is fixedly connected to the right end of the positioning block, and the other end of the spring is fixed to the access end.

[0008] The effect achieved by the above components is that the positioning block is fully retracted into the access end by the pulling mechanism, thereby compressing the spring.

[0009] Preferably, a pull rope is fixedly connected to the right end of the positioning block, and the pull rope passes through the access end.

[0010] The effect achieved by the above components is that pulling the pull rope causes the positioning block to retract completely into the access end.

[0011] Preferably, the outer connector has a sliding ring slidably connected to its arc surface, and the sliding ring is fixed to the pull rope.

[0012] The effect achieved by the above components is that the downward sliding ring pulls the rope.

[0013] Preferably, the left end of the positioning block has a sliding surface.

[0014] The effect achieved by the above components is that, by setting a sliding surface, the auxiliary positioning block is inserted into the sliding end.

[0015] Preferably, a sealing ring is provided between the access end and the sliding end, the sealing ring being used to seal between the access end and the sliding end.

[0016] The effect achieved by the above components is to seal the connection between the inlet and the sliding end by setting a sealing ring.

[0017] Preferably, a second check valve is installed on the arc surface of the second drive pipe, and a third check valve is installed on the arc surface of both the first input pipe and the second input pipe.

[0018] The effect achieved by the above components is as follows: by setting a second one-way valve, the gas can flow to the first extinguishing agent cylinder, but not vice versa; by setting a third one-way valve, the gas in the first input pipe and the second input pipe can only flow to the high-pressure hose gas, and cannot flow in the other direction.

[0019] Preferably, a fourth one-way valve is installed on the arc surface of the fourth drive pipeline.

[0020] The effect achieved by the above components is that by setting a fourth one-way valve, gas can flow to the second extinguishing agent cylinder, but cannot flow in the opposite direction.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up a convenient fixing component, when conveniently fixing the external pipe to the external connector, the pulling mechanism allows the positioning block to be fully retracted into the access end, compressing the reset mechanism. Then, the sliding end is dragged into the access end, and the pulling mechanism is released, causing the reset mechanism to reset and the positioning block to be inserted into the sliding end. This achieves the effect of conveniently fixing the external pipe to the external connector as much as possible, solving the problem that since the external connector needs to be connected to the external pipe in the fireproof zone, the connection between the external connector and the external pipe usually involves inserting the external pipe into the external connector and then using a tightening tool to tighten the clamp to fix the external connector and the external pipe, which may make the entire installation process more complicated.

Solenoid valves are installed at the upper ends of the first nitrogen cylinder 1, the second nitrogen cylinder 4, the first extinguishing agent cylinder 5, and the second extinguishing agent cylinder 6.

[0029] Reference Figure 2 and Figure 3As shown in this embodiment: the convenient fixing component 2 includes an access end 21 fixedly connected to the upper end of the external connector 18. A sliding end 24 is slidably connected to the arc surface of the access end 21. An external tube 23 is fixedly connected to the upper end of the sliding end 24. A positioning block 22 is slidably inserted into the arc surface of the access end 21 and inserted into the sliding end 24. By setting the convenient fixing component 2, when conveniently fixing the external tube 23 to the external connector 18, the positioning block 22 is completely retracted into the access end 21 by a pulling mechanism, compressing the reset mechanism. Then, the sliding end 24 is dragged into the access end 21. Releasing the pulling mechanism resets the reset mechanism, allowing the positioning block 22 to be inserted into the sliding end 24, thereby maximizing the convenience of fixing the external tube 23 to the external connector 18. A spring 26 is fixedly connected to the right end of the positioning block 22. The other end of the spring 26 is fixed to the access end 21. By pulling the mechanism, the positioning block 22 is completely retracted into the access end 21, which compresses the spring 26. The right end of the positioning block 22 is fixedly connected to a pull rope 27, which passes through the access end 21. Pulling the pull rope 27 causes the positioning block 22 to be completely retracted into the access end 21. The arc surface of the outer connector 18 is slidably connected to a slip ring 28, which is fixed to the pull rope 27. Sliding the slip ring 28 downward causes the pull rope 27 to be pulled. The left end of the positioning block 22 has a sliding surface 25. By setting the sliding surface 25, the positioning block 22 is assisted in being inserted into the sliding end 24. A sealing ring 29 is set between the access end 21 and the sliding end 24. The sealing ring 29 is used to seal between the access end 21 and the sliding end 24.

[0030] Reference Figure 1 As shown in this embodiment: a second one-way valve 10 is installed on the arc surface of the second drive pipe 9, and a third one-way valve 13 is installed on the arc surface of both the first input pipe 12 and the second input pipe 14. By setting the second one-way valve 10, gas can flow to the first extinguishing agent bottle 5, but not vice versa. By setting the third one-way valve 13, gas from the first input pipe 12 and the second input pipe 14 can only flow to the high-pressure hose gas, and cannot flow in the other direction. A fourth one-way valve 16 is installed on the arc surface of the fourth drive pipe 15. By setting the fourth one-way valve 16, gas can flow to the second extinguishing agent bottle 6, but cannot flow in the other direction.

[0031] Working principle:

[0032] When using the automatic distribution device, the controller activates the solenoid valve on the first nitrogen cylinder 1, causing the nitrogen to flow from the first nitrogen cylinder 1 through the first drive line 7 to the first electric selector valve 8. Simultaneously, the controller activates the first electric selector valve 8 (the electric selector valve can be model D941X-16PQC), causing the gas to flow through the second drive line 9. This also opens the solenoid valves on the first extinguishing agent cylinder 5 and the second extinguishing agent cylinder 6, allowing the gas to flow to the high-pressure hose. Meanwhile, the second electric rotary valve remains closed, and the gas finally flows from the external connector 18 connected to the first electric selector valve 8. To the larger fire zone No. 1; the controller activates the solenoid valve on the second nitrogen cylinder 4, causing nitrogen to flow through the third drive line 19 to the second electric selector valve 17. Simultaneously, the controller activates the second electric selector valve 17, causing nitrogen to flow through the fourth drive line 15 to the second drive line 9. Because the second drive line 9 is equipped with a first one-way valve 11, the gas will not flow to the first extinguishing agent cylinder 5. At the same time, the solenoid valve on the second extinguishing agent cylinder 6 (model ZC can be selected) is opened, allowing the gas to flow to the high-pressure hose. Meanwhile, the first electric rotary valve is in the closed state. This allows the gas to flow to the smaller fire zone 1, via the external connector 18 connected to the second electric selector valve 17, thus achieving automated distribution. The extinguishing agent cylinder contains the highly efficient gaseous extinguishing agent heptachloropropane. When conveniently fixing the external pipe 23 to the external connector 18, the slip ring 28 is slid downwards, pulling the rope 27 and causing the positioning block 22 to fully retract into the access end 21, compressing the spring 26. Then, the sliding end 24 is dragged into the access end 21, releasing the slip ring 28, causing the spring 26 to reset, and allowing the positioning block 22 to insert into the sliding end 24, thereby maximizing the desired effect. To facilitate the fixing of the external pipe 23 to the external connector 18, a sliding surface 25 is provided, an auxiliary positioning block 22 is inserted into the sliding end 24, a sealing ring 29 is provided to seal the connection end 21 and the sliding end 24, a second one-way valve 10 is provided to allow gas to flow to the first extinguishing agent cylinder 5, and vice versa, a third one-way valve 13 is provided to allow gas from the first input pipe 12 and the second input pipe 14 to flow only to the high-pressure hose, and vice versa, and a fourth one-way valve 16 is provided to allow gas to flow to the second extinguishing agent cylinder 6, and vice versa.
