The opening hole plugging device is composed of three kinds of machines, such as an opening machine, an occluder and a lower closure device. The utility model is composed of a fan-shaped plywood valve, an upper and lower connector, a left and right positioning device, a temporary bypass interface, a discharge valve, a pressure meter and other parts. The utility model provides a support for an opening machine, an occluder and a lower closure, and simultaneously utilizes the left and right fixing device to fix the PE pipe in operation to be clamped tightly. Under the PE connector pipe and special connection and sealing; on the connector and the opening machine, respectively, under the occluder connection and sealing device; the fan-shaped valve is an important device to implement splint hole plugging process equipment for the spring must be open and close, frame materials by Aluminum Alloy, treated by anodic oxidation process with surface high hardness, corrosion resistance, abrasion resistance, light weight and so on.
Opening machine is composed of drill pipe, hole cutter, differential feed mechanism and a connecting plate, a casing, sheath and hand manipulation of parts, machine adopts manual hole, hole cutting knife, drill pipe automatic differential feed, block hole knife center drill centering and bring out after cutting the whole. The machine has the advantages of compact structure, compact and lightweight, simple operation and labor saving.
The occluder is composed of a main shaft, an eccentric connecting disc, a folding leather bowl, a sealing head, a control device and a mechanical part. The plugging device is the key equipment for plugging and cutting off the medium circulation of the pipe after opening. The effect and reliability achieved are the key to the plugging technique. It uses the eccentric swinging device and spherical connecting plate folding cup will have good plugging head into the hole in the side of the plugging head through the lever open, and use the pressure of the pipeline to promote skin head sealing cone seal more tightly in the bowl.
Under the occluder is connected with a wheel clamp block and lever parts, its function is in the plugging holes after plugging special electric melting PE pipe plug mouth next block sealing plug. The left and right clamp block is installed on the lower end of the main shaft, when the work will block around the closure of special electric melting PE pipe plug, a movable pin and position control device on the spindle
