The Hole Sealing Equipment is composed of three different types of machinery: the Hole Punching Machine, the Sealing Device, and the Lower Sealing Device. They share a common frame, which is made up of parts such as the sector gate valve, upper and lower connectors, left and right positioning fixtures, temporary bypass connections, relief valves, and pressure gauges. The frame serves as a support for the Hole Punching Machine, Sealing Device, and Lower Sealing Device, and uses its left and right fixing devices to connect and securely clamp the running PE pipeline. The lower connector is connected and sealed to the PE pipe fittings; the upper connector connects and seals to the Hole Punching Machine, Sealing Device, and Lower Sealing Device; the sector gate valve is an essential device for opening and closing during the equipment spring change in the hole sealing process. The frame is made of aluminum alloy, treated by anodizing, and features high surface hardness, corrosion resistance, wear resistance, and light weight.
