[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 The utility model provides a technical solution: a city gas pressure regulating and conveying device, comprising a fixed base 1, the upper end of the fixed base 1 is clamped and sleeved with a storage tank 2, the gas outlet end of the storage tank 2 is connected with a pressure regulating valve 3, the upper end of the storage tank 2 is connected with an automatic pressure relief pipe 4, the automatic pressure relief pipe 4 is sealed and sleeved with a channel pipe 5 through a fixed buckle 17, one end of the channel pipe 5 is connected with a collection tank 6, and one end of the channel pipe 5 is fixedly connected with a one-way valve 7.

[0019] In the present embodiment, the gas can be stored by the storage tank 2, and the pressure can be adjusted by the pressure regulating valve 3. When the internal storage capacity of the storage tank 2 is too large, the internal pressure is too high, which will cause the excess gas to be discharged through the automatic pressure relief pipe 4, and flow to the interior of the collection tank 6 through the channel pipe 5 for storage and collection. At the same time, the one-way valve 7 can prevent the gas from flowing back and affecting the interior of the storage tank 2. This design can automatically relieve the pressure of the storage tank 2, avoid excessive storage capacity, resulting in high internal pressure, and prone to explosions and other accidents in hot weather, and has a good protective effect.

[0020] Specifically, a return spring 8 is fixedly connected to the interior of the automatic pressure relief pipe 4 , one end of the return spring 8 is fixedly connected to a piston block 10 , and a pressure relief port 9 is opened on one side of the exterior of the automatic pressure relief pipe 4 .

[0021] In this embodiment, by providing a reset spring 8, when the storage volume of the storage tank 2 is too large, the piston block 10 can be pushed to slide. When the piston block 10 slides to the pressure relief port 9, the excess gas can be discharged into the collection tank 6 for collection. After the pressure relief is completed, under the elastic action of the reset spring 8, the piston block 10 can block the automatic pressure relief pipe 4 and seal it.

[0022] Specifically, the lower end of the fixed base 1 is fixedly connected with a supporting footnote 11, and the number of the supporting footnotes 11 is four.

[0023] In this embodiment, the support footnote 11 is provided to facilitate support.

[0024] Specifically, air inlets 12 are fixedly opened at the upper ends of both sides of the fixed base 1 , air outlets 13 are fixedly opened at both sides of the fixed base 1 , and cooling fans 14 are fixedly connected inside the air outlets 13 .

[0025] In this embodiment, when the heat dissipation fan 14 is powered on, it can be driven to rotate, thereby dissipating heat inside the fixed base 1.

[0026] Specifically, the cooling fan 14 is electrically connected to the battery 16 via a wire, the battery 16 is fixedly connected to one side of the back of the fixed base 1, and a cooling sheet 15 is fixedly embedded on the inner side of the fixed base 1, and the cooling sheet 15 is electrically connected to the battery 16 via a wire.

[0027] In this embodiment, after the power is turned on, the refrigeration plate 15 can cool and dissipate heat to the storage tank 2 through the inner refrigeration surface, so that the storage tank 2 can be quickly cooled, and the heat dissipation surface of the refrigeration plate 15 can be quickly cooled by the heat dissipation fan 14. This design method can quickly cool down and dissipate heat for the storage tank 2, avoids damage to the tank body due to long-term high-temperature use, and has a good protective effect on the storage tank 2.
