The friction ring 49 is provided with friction lines on the side adjacent to the movable ring 41. The friction lines cooperate with the movable ring 41 to enhance the performance of the overall device and achieve the purpose of self-locking. A cavity is provided inside the screw rod 43, and the shape of the cavity is a convex letter shape, which makes the entire structural design more compact and can use a smaller space to achieve the purpose of actual needs. A limiting block is provided on the end face of the connecting rod 411 located inside the ring gear 47. The cross-sectional area of ​​the limiting block is larger than the cross-sectional area of ​​the connecting rod 411, which improves the stability of the connection relationship between the components in the overall structure, thereby ensuring the stability of the overall device.

[0025] The explosion-proof component 3 includes a pressure relief pipe 31, a fixed seat 32, a slide plate 33, a seal 34, a return spring 35, a limit cylinder 36 and a pressure plate 37. The pressure relief pipe 31 is arranged on the fixed seat 32, the fixed seat 32 is fixedly installed on the surface of the main water pipe 1, the slide plate 33 is slidably arranged inside the fixed seat 32, the seal 34 is fixedly installed on the bottom surface of the slide plate 33, the two ends of the return spring 35 are respectively fixedly connected to the slide plate 33 and the pressure plate 37, the limit cylinder 36 is fixedly arranged on the top surface of the inner cavity of the fixed seat 32, and the pressure plate 37 is slidably arranged inside the limit cylinder 36, so that the overall structure has the function of diversion and pressure relief, thereby achieving the effect of water pipe explosion prevention.

[0026] Working principle: when the pressure inside the main water pipe 1 is too high, the generated pressure acts on the seal 34 fixed on the slide plate 33, and the slide plate 33 is in a slidable state inside the fixing seat 32 fixed on the main water pipe 1, so the seal 34 and the slide plate 33 will be pushed open, revealing the holes on the main water pipe 1. At this time, the water flow inside the main water pipe 1 enters the fixing seat 32 and is diverted through the pressure relief pipe 31 on the fixing seat 32, thereby achieving the effect of pressure relief and explosion prevention. After the pressure relief is completed, under the action of the return spring 35 fixedly connected to the pressure plate 37 and the slide plate 33 at both ends, the slide plate 33 slides toward the main water pipe 1, so that the seal 34 blocks the holes on the main water pipe 1 again.

[0027] When it is necessary to adjust the pre-deformation of the return spring 35 so that the whole is suitable for use with different water flow pressures, push the movable ring 41 and then rotate the movable ring 41. The connecting rod 411 fixedly connected to the movable ring 41 is plugged into the ring gear 47. At the same time, the two ends of the auxiliary spring 410 are respectively fixedly connected to the ring gear 47 and the movable ring 41. At this time, the movable ring 41 is not in contact with the friction ring 49 fixed on the base 2. The ring gear 47 rotatably connected to the other base 2 will rotate with the rotation of the movable ring 41. The ring gear 47 is meshed with the transmission gear 46. The gear shaft of the transmission gear 46 is fixed with a second bevel gear 45 meshed with the first bevel gear 44. Therefore, the first bevel gear 44 rotates synchronously. The first bevel gear 44 is fixed with the screw rod 43 movably set on the connecting seat 48 The screw 43 rotates synchronously, and the connecting tube 42 slidably set on the pressure relief pipe 31 is fixedly connected to the pressure plate 37, and is also threadedly connected to the screw 43. At this point, as the movable ring 41 drives the ring gear 47, the transmission gear 46, the second bevel gear 45, the screw 43 and the first bevel gear 44 to rotate, the connecting tube 42 will push the pressure plate 37 to slide inside the limit tube 36, thereby changing the pre-deformation of the reset spring 35, and then release the movable ring 41. Under the action of the auxiliary spring 410, the movable ring 41 slides toward the friction ring 49 until it contacts the friction ring 49. At this time, the friction pattern on the friction ring 49 cooperates with the movable ring 41, thereby limiting the rotation of the movable ring 41 and achieving the effect of locking the overall structure.
