Problems solved by technology

[0003] However, during the construction process, when it is necessary to connect two pipes, the usual method is to precisely align the two pipes, and then use a hot-melt machine to carefully perform hot-melt welding at the seams, so as to realize the combination of the two pipes , this method is not only inconvenient to operate, but also costly

Embodiment 1

[0020] Embodiment 1 is basically as attached figure 1 , figure 2 Shown: The pipe joint sealing equipment includes a small air pump, an outer fixing ring, an inner fixing ring and an air bag, and also includes a plug storage box, which is detachably connected to the small air pump; the outer diameter of the inner fixing ring is smaller than that of the pipe Inner diameter, the inner diameter of the outer fixing ring is larger than the outer diameter of the pipe, the airbag is circular and consists of two pieces, the outer wall of the airbag is provided with a strong adhesive layer and bonded between the inner fixing ring and the outer fixing ring, the thickness of the strong adhesive layer is 1-3cm ; Through practice, the strong adhesive layer within this range has the best effect when sealing the pipe joints. There are air holes on the outer fixing ring or inner fixing ring, and plugs are set on the air holes, and the plug storage box is fixed on the small air pump by Velcro...

Embodiment 2

[0025] The only difference from Embodiment 1 is that the plug storage box is embedded in the handle of the small air pump; it is convenient to carry and saves space.

Abstract

The invention discloses pipe joint sealing equipment. The pipe joint sealing equipment comprises a small inflation pump and airbags; the outer diameter of an inner fixing ring is smaller than the inner diameter of a pipe; the inner diameter of an outer fixing ring is larger than the outer diameter of the pipe; the airbags are annular; two airbags are arranged; mighty glue layers are arranged on the outer walls of the airbags, and are bonded between the inner fixing ring and the outer fixing ring; an air hole is formed in the outer fixing ring or the inner fixing ring; and a plug is arranged in the air hole. The pipe joint sealing equipment is convenient to operate, low in cost and high in efficiency.

Description

technical field [0001] The present invention relates to pipe joint sealing equipment. Background technique [0002] Hollow wound pipe is a kind of pipe made of high-density polyethylene (HDPE) by winding and welding. Due to its unique forming process, it can produce pipes with a diameter of up to 3 meters. [0003] However, during the construction process, when it is necessary to connect two pipes, the usual method is to precisely align the two pipes, and then use a hot-melt machine to carefully perform hot-melt welding at the seams, so as to realize the combination of the two pipes , this method is not only inconvenient to operate, but also expensive. Contents of the invention [0004] The invention intends to provide a pipe seam sealing device to facilitate operation and reduce cost. [0005] In the basic plan: pipe joint sealing equipment, including a small air pump, an outer retaining ring, an inner retaining ring and an air bag, the outer diameter of the inner retai...
