[0033] The following is in conjunction with the appendix Figs. 1-3 The present invention will be further described in detail with reference to the embodiments.

[0034] Example 1

[0035] Electronically controlled diverter nozzles, including

[0036] T-junction 1, which is provided with a channel 11 for conveying extinguishing agent; in other embodiments, the extinguishing medium may also be water.

[0037] The nozzle 12 is fixed on the tee 1 and is used to release the extinguishing medium. The side wall of the nozzle 12 is provided with a number of nozzle holes.

[0038] Valve core 2 is installed in channel 11 and is used to control the connection or disconnection between channel 11 and nozzle 12. Valve core 2 does not disconnect channel 11, that is, channel 11 is normally open. When valve core 2 is sealed at the port of nozzle 12, the extinguishing agent can flow from one end of channel 11 to the other end.

[0039] The electric starter 3, in this embodiment, is an electromagnetic starter. The electric starter 3 is installed on one port of the three-way 1 and forms a chamber 100 with the valve core 2. The electric starter 3 is used to control the movement of the valve core 2. After the electric starter 3 is started, the channel 11 is connected to the nozzle 12.

[0040] The nozzle 12 is integrally formed on the tee 1. When the valve core 2 is not installed, the nozzle 12 is connected to the channel 11.

[0041] The valve core 2 is provided with a first vent hole 21, which is located on the side of the valve core 2. The chamber 100 is connected to the channel 11 through the first vent hole 21.

[0042] The valve core 2 is also provided with a second vent 22 for connecting the chamber 100 and the nozzle 12. The second vent 22 is located in the axial position of the valve core 2 and passes through the upper and lower end faces of the valve core 2. When the electric starter 3 pushes the valve core 2 downward, the valve core 2 is sealed at the port of the nozzle 12, and the channel 11 is isolated from the nozzle 12. At this time, the electric starter 3 is sealed at the port of the second vent 22. When the electric starter 3 is removed from the port of the second vent 22, the air pressure in the chamber 100 will be released to the nozzle 12 through the second vent 22. At this time, the air pressure in the channel 11 is greater than the air pressure in the chamber 100, and the valve core 2 will be lifted and removed from the port of the nozzle 12. The valve core 2 moves upward and connects the channel 11 with the nozzle 12.

[0043] The electric starter 3 includes a lifting rod 31, the end of which is fitted with a sealing gasket 32 ​​for sealing with the second vent 22.

[0044] The electric starter 3 includes a guide sleeve 33, which is fitted onto the lifting rod 31 and sealed onto the tee 1. The lifting rod 1 extends out of the guide sleeve 33 and is sealed to the valve core 2. The guide sleeve 33 is threaded to the tee 1, and the connection between the guide sleeve 33 and the tee 1 is sealed with a sealing ring. An elastic element 4, which is a spring, is provided between the guide sleeve 33 and the lifting rod 31. When the valve core 2 is sealed at the nozzle 12 port, there is a gap 200 between the valve core 2 and the guide sleeve 33, which is the stroke distance of the valve core 2 during upward movement.

[0045] The valve core 2 includes an upper core body 23 and a lower core body 24. The lower core body 24 is threadedly connected to the upper core body 23. A second vent hole 22 extends from the upper core body 23 to the lower core body 24. The upper core body 23 is sealed to the tee 1 via a first sealing ring 5. The lower core body 24 is installed at the lower end of the upper core body 23. A second sealing ring 6 is installed between the lower core body 24 and the upper core body 23 for sealing with the nozzle 12 port. The valve core 2 is sealed at the nozzle 12 port by the second sealing ring 6. When the lower core body 24 is locked to the upper core body 23, the second sealing ring 6 is squeezed and deformed by the lower core body 24. The deformed second sealing ring 6 forms a larger sealing surface with the nozzle 12 port, improving the sealing effect.

[0046] The left end of the tee 1 is provided with a first pipe connector 13, and the right end is provided with a second pipe connector 14. The electric starter 3 is located at the upper end of the tee 1, and the nozzle 12 is located at the lower end of the tee 1.

[0047] Working principle: During electric start-up, power is supplied to the electric starter 3. Upon power-up, the electric starter generates a magnetic force, pulling the lifting rod 31 upwards. At this time, the air pressure inside the chamber 100 is released to the nozzle 12 through the second vent 22, creating a pressure differential between the chamber 100 and the channel 11. The valve core 2 is directly opened by the air pressure, thus connecting the channel 11 and the nozzle 12. When the valve needs to be reset, the power supply to the electric starter 3 is directly disconnected. At this time, under the action of the elastic element 4, the lifting rod 31 re-seales with the boss of the valve core 2. The air pressure inside the chamber 100 is replenished through the first vent 21, the valve core 2 resets, and the connection between the channel 11 and the nozzle 12 is severed, realizing electric start-up and reset.

[0048] Example 2

[0049] Example 2 is basically the same as Example 1, except that the nozzle 12 is fastened to the tee 1 by means of threads.

[0050] Example 3

[0051] The pipeline fire extinguishing equipment includes a first discharge pipe, a second discharge pipe, and an electrically controlled diversion nozzle as described in Embodiment 1 or 2. One end of the electrically controlled diversion nozzle is connected to the first discharge pipe, and the other end is connected to the second discharge pipe.
