The perforation and sealing equipment consists of three different-purpose machines: a perforator, a sealing device, and a lower sealing device. They share a common frame, which is made up of components such as a sector gate valve, upper and lower connectors, left and right positioning fixtures, temporary bypass connections, vent valves, and pressure gauges. The frame serves as a support for the perforator, sealing device, and lower sealing device, and also uses its left and right fixing devices to connect and securely clamp the running PE pipes. The lower connector connects and seals with PE pipe fittings; the upper connector connects and seals with the perforator, 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 perforation and sealing process. The frame is made of aluminum alloy, treated with anodizing, featuring high surface hardness, corrosion resistance, wear resistance, and light weight.
