High-pressure quick-opening manhole with self-locking function

Abstract

This utility model relates to the field of high-pressure quick-opening manhole technology, and in particular to a high-pressure quick-opening manhole with a self-locking function. It includes a flange seat assembly, with screws rotatably connected to the inner side of the flange seat assembly. An end cap assembly is installed on the upper end of the flange seat assembly. The flange seat assembly includes a seat body, which is integrally fixed with a cylindrical shell. A groove and a vent hole are opened on the inner side of the cylindrical shell. An arc-shaped pipe is fixedly connected to the outer side of the cylindrical shell, and a solenoid valve is fixedly connected to the front end of the arc-shaped pipe. A check valve is fixedly connected to the inner side of the groove in the cylindrical shell. The end cap assembly includes a fixing plate, with a ring plate fixedly connected to one side of the fixing plate. A sliding hole is opened on the inner side of the ring plate, and a spring is fixedly connected to the upper end of the ring plate. A guide post is fixedly connected to the upper end of the spring. In this utility model, before opening the cap, the operator can move away from the device, thereby preventing incomplete depressurization of the container or a sudden increase in residual pressure that could cause the end cap to eject or the medium to spray out, endangering the safety of on-site personnel.
