Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a quick plugging device, which includes a bladder body 1, a connecting pipe 2 and a gas transmission pipe 3. One side of the bladder body 1 is communicated with a connecting joint 4. The connecting joint 4 is fixed to one end of the connecting pipe 2 through a hose clamp 13. The other end of the connecting pipe 2 and the gas transmission pipe 3 are detachably installed together through a connecting component. The connecting component includes a quick joint 5 fixed to one end of the gas transmission pipe 3 through a hose clamp 13. One end of the connecting pipe 2 far from the bladder body 1 is fixedly installed with a one-way air valve 6 through a hose clamp 13. The gas transmission pipe 3 and the connecting pipe 2 are fixedly connected together through the quick joint 5 and the one-way air valve 6.

[0021] In this embodiment, the bladder body 1, the connecting pipe 2 and the gas transmission pipe 3 are connected in sequence. When installing the bladder body 1 and the connecting pipe 2, the user can insert the connecting joint 4 on one side of the bladder body 1 into one end of the connecting pipe 2, and then lock and fix the connecting joint 4 to one end of the connecting pipe 2 through the hose clamp 13, so as to connect the bladder body 1 and the connecting pipe 2 together. When installing the connecting pipe 2 and the gas transmission pipe 3, the user can lock and fix the one-way air valve 6 to one end of the connecting pipe 2 through the hose clamp 13, and then lock and fix the quick joint 5 to one end of the gas transmission pipe 3 through the hose clamp 13. After the one-way air valve 6 and the quick joint 5 are installed, the user can insert one end of the one-way air valve 6 into one end of the quick joint 5, so as to quickly connect the gas transmission pipe 3 and the connecting pipe 2. Through the setting of the one-way air valve 6, it can inflate the inside of the bladder body 1 unidirectionally and is also convenient for deflation operation.

[0022] In addition, in this embodiment, the pressure that the bladder body 1 can withstand is less than 0.2 Mpa, and the pressure that the connecting pipe 2 and the gas transmission pipe 3 can withstand is less than 1 Mpa.

[0023] The surface of the connecting pipe 2 is provided with a handheld component for conveniently moving the bladder body 1 to the part of the gas pipeline that needs to be plugged. The handheld component includes a heat-insulating sleeve 7 sleeved on the surface of the connecting pipe 2.

One end of the T-shaped pipe 11 is fixedly connected with one end of the gas transmission pipe 3 through a hose clamp 13, and the other end of the T-shaped pipe 11 is communicated with an air inlet joint 12.

[0026] In this embodiment, the air inlet assembly includes a T-shaped pipe 11, a pressure gauge 10 and an air inlet joint 12, which are installed at one end of the gas transmission pipe 3. When installing, the user can install the pressure gauge 10 on the T-shaped pipe 11, and then fix one end of the T-shaped pipe 11 on one end of the gas transmission pipe 3 through the hose clamp 13. When moving the bladder body 1 to the position inside the gas pipeline for blocking, the user can connect the air inlet joint 12 with an external gas source, and then inject gas into the bladder body 1 to make it expand to block the position inside the gas pipeline. When injecting gas into the bladder body 1, the user can monitor the pressure state inside the bladder body 1 in real time through the pressure gauge 10.
