Specifically, the left edge of the water outlet 11 is integrally formed with a connecting flange 5, and the connecting flange 5 is used to connect a fire-fighting water pipe, so as to more quickly put out fires.

Specifically, the outer surface of the water inlet 12 is evenly and integrally formed with two clamping edges 6 , the design of the two clamping edges 6 makes the connection between the water inlet 12 and the water supply device more tightly, and avoids water leakage at the connection.

Working principle: Connect the water inlet 12 of the water pipe 1 with the output end of the water supply device, put the fire-fighting water pipe on the water outlet 11, and when a fire occurs, quickly turn the rotary switch 45 of the valve switch 4 counterclockwise, and the rotary switch 45 drives the lower The connecting column 41 and the diamond-shaped connecting column 43 rotate, and the rhombus-shaped connecting column 43 is located in the cavity 22, which does not affect the rotation of the valve switch 4. The external thread 42 on the connecting column 41 is screwed out from the internal thread through hole 23, and is located in the first The spring 33 between the limit edge 32 and the bottom surface of the cavity 22 recovers from the compressed state, and the elastic force generated by the spring 33 bounces up the first limit edge 32, and the first limit edge 32 pushes the valve switch 4 to move upward, and the valve switch 4, the longer diagonal of the diamond-shaped connecting column 43 slides upwards in the chute 24, and the rhombus-shaped connecting column 43 is located in the chute 24, hindering the rotation of the valve switch 4, preventing misoperation when the fire valve is opened, and turning the valve switch 4. The operation of the fire valve causes adverse effects. At the same time, the spring 33 drives the connecting rod 3 to move upward by bouncing the first limit edge 32. The connecting rod 3 drives the rubber plug 31 to move upward, and the rubber plug 31 is pulled out from the bottom of the water outlet 13. Allow the water flow to enter the water outlet 11 from the water inlet 12 to realize the opening of the fire valve to extinguish the fire. After the fire is extinguished, press the valve switch 4, and the diamond-shaped connecting column 43 slides downward in the chute 24 until the external thread 42 and The internally threaded through hole 23 is in contact, and the switch 46 is rotated clockwise to reconnect the external thread 42 and the internally threaded through hole 23. Press the first limit edge 32, the first limit edge 32 compresses the spring 33, and at the same time the connecting rod 3 drives the rubber plug 31 to move down, the rubber plug 31 is inserted into the bottom end of the water outlet 12, and the rubber plug 31 and the bottom end of the water outlet 12 The outer wall is in close contact, which prevents the water flow from entering the water outlet 11 from the water inlet 12, realizes the closing of the fire valve, and avoids the waste of water resources. Rescue, do not waste a minute and a second of rescue time, reduce the harm caused by the fire to people, after the rescue, you can close the fire valve in time to stop the external drainage.
