DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Embodiment 1

[0020] See also Figure 1-3 An antifreeze pressure regulating valve includes a pressure regulating valve body 1. The material of the pressure regulating valve body 1 is a corrosion-resistant and low-temperature-resistant metal material. A connecting groove is provided in the middle of the pressure regulating valve body 1. The setting of the corrosion-resistant and low-temperature-resistant metal material of the pressure regulating valve body 1 can effectively extend the service life. An adjusting rod 2 is rotatably connected to one side of the pressure regulating valve body 1. A pressure gauge 3 is provided on the top of the pressure regulating valve body 1. Fixed anti-leakage devices 4 are provided on both sides of the pressure regulating valve body 1:

[0021] The fixed anti-leakage device 4 includes a base 41, which is fixedly connected to the inside of the connecting groove of the pressure regulating valve body 1. An air pipe 43 passes through and is fixedly connected to the inner wall of the base 41. The base 41 can effectively provide a support seat for the airbag 42. The material of the airbag 42 is a one-way air intake material and can perform automatic air inhalation. An airbag 42 is fixedly connected to one side of the base 41, an air pipe 43 is fixedly connected to one side of the airbag 42, and a sealed expansion airbag 44 is fixedly connected to the other side of the air pipe 43. One side of the sealed expansion airbag 44 is fixedly connected to the inside of the connecting groove of the pressure regulating valve body 1. The sealed expansion airbag 44 is made of a material with good sealing performance. The sealed expansion airbag 44 can effectively seal and fix the connection between the water pipe and the pressure regulating valve body 1. The present application can squeeze the airbag 42 after the water pipe and the regulating valve body 1 are connected by fixing the anti-leakage device 4. After being squeezed, the airbag 42 will transport the internal gas to the sealed expansion airbag 44 through the air pipe 43, and the sealed expansion airbag 44 will expand to seal and fix the connection between the water pipe and the pressure regulating valve body 1, which is highly practical.

[0022] When in use, first dock the water pipe with the connecting groove of the pressure regulating valve body 1. After the water pipe slides into the connecting groove in the pressure regulating valve body 1, it will squeeze the airbag 42 in the connecting groove. After being squeezed by one side of the water pipe, the airbag 42 will transport the internal gas to the sealed expansion airbag 44 through the air pipe 43. After the sealed expansion airbag 44 is injected with gas, it will expand, and the connection between the water pipe and the pressure regulating valve body 1 will be sealed and fixed to prevent the water pipe and the pressure regulating valve body 1 from being unstable. It can also effectively prevent the water pipe and the pressure regulating valve body 1 from being unstable due to the connection. The water pipe and the pressure regulating valve body 1 are highly practical. If it is necessary to separate the water pipe from the pressure regulating valve body 1, it is only necessary to discharge the gas in the sealed expansion airbag 44 through the exhaust valve 54. The sealed expansion airbag 44 will return to its original position after the internal gas is discharged. At this time, the user can separate the water pipe from the pressure regulating valve body 1. After separation, due to the setting of the one-way air intake material of the airbag 42, the airbag 42 will automatically inhale and slowly return to the expanded state, which is convenient for the next use.

[0023] Embodiment 2

[0024] See also Figure 1-4 On the basis of the first embodiment, a heat preservation device 5 is further provided on both sides of the pressure regulating valve body 1:

[0025] The heat preservation device 5 includes a connecting pipe 51, one side of which is fixedly connected to the gas delivery pipe 43, the connecting pipe 51 and the gas delivery pipe 43 penetrate and are fixedly connected inside the pressure regulating valve body 1, and the connecting pipe 51 can deliver the gas in the airbag 42 to the air pressure cabin 52. The other side of the connecting pipe 51 is fixedly connected to the air pressure cabin 52, and the air pressure cabin 52 is fixedly connected to both sides of the pressure regulating valve body 1. The air pressure insulation sleeve 53 is made of a material with good heat preservation performance. After the air pressure cabin 52 is injected with gas, it can effectively drive the air pressure insulation sleeve 53 to move. A pressure insulation sleeve 53 is slidably connected to one side of the pressure cabin 52, and an exhaust valve 54 is arranged on the top of the pressure cabin 52. The present application uses the insulation device 5 to transport the internal gas to the pressure cabin 52 through the connecting pipe 51 after the air bag 42 is squeezed. The pressure cabin 52 will drive the pressure insulation sleeve 53 to insulate the outside of the water pipe and the pressure regulating valve body 1, so as to prevent the connection between the water pipe and the pressure regulating valve body 1 from bursting under low temperature conditions, which will affect the use of the entire device.

[0026] When in use, on the basis of the first embodiment, the water pipe and the connecting groove of the pressure regulating valve body 1 are connected, and one side of the water pipe will squeeze the airbag 42. After being squeezed, the airbag 42 will transport the internal gas to the connecting pipe 51 through the gas pipe 43. The connecting pipe 51 will transport the gas to the inside of the air pressure cabin 52. After the air is injected into the air pressure cabin 52, it will drive the air pressure insulation sleeve 53 to move. The air pressure insulation sleeve 53 will insulate and protect the outside of the connection between the water pipe and the pressure regulating valve body 1 for a distance to prevent the water from being heated at a low temperature. Under the high temperature, the connection between the water pipe and the pressure regulating valve body 1 bursts, causing the entire device to be unusable, further enhancing the practicality of the entire device. When the water pipe needs to be replaced or the entire device needs to be removed, it is only necessary to discharge the gas in the pressure chamber 52 through the exhaust valve 54. After the gas in the pressure chamber 52 is completely discharged, the pressure insulation sleeve 53 will return to its original position without the drive of gas. At this time, the user can easily take out the water pipe for replacement, or remove the entire device, which is convenient, fast and simple to operate.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
