Description

Mechanical sealing element convenient to use

Technical Field

The utility model relates to a pipeline sealing equipment technical field especially relates to a mechanical seal spare convenient to use.

Background

The method for connecting the pipeline-pipeline connecting pipes, the pipe connecting pieces, the valves and the inlet and outlet connecting pipes on the equipment is determined by the properties, pressure and temperature of fluid, the material, size and installation place of the pipes and other factors, and mainly comprises 4 methods of screw thread connection, flange connection, socket connection, welding and the like, wherein the method comprises the following steps: is mainly suitable for small-diameter pipelines. During connection, fluoroplastic sealing tape is wound on the threaded connection part, or thick paint is coated on the threaded connection part, or hemp thread is wound on the threaded connection part, so as to prevent leakage. At pressures above 1.6 mpa, the tube ends are typically gasketed. The connection method is simple, and can be disassembled and reassembled, but a movable joint needs to be installed at a proper position of the pipeline so as to be convenient for disassembly and assembly. Connecting flanges: the applicable diameter range is large. During connection, different flanges and sealing gaskets are selected according to the property, pressure and temperature of fluid, and the gaskets are clamped by bolts to keep sealing. The flange connection is adopted at most of the pipe sections which need to be frequently disassembled and assembled and the places where the pipelines are connected with the equipment. Thirdly, socket joint connection: it is used for the connection between cast iron pipe, concrete pipe, pottery clay pipe and their connectors, and is only suitable for water supply, drainage and gas pipeline working under low pressure and normal temperature. During connection, hemp thread, cotton thread or asbestos rope is filled into the socket, then asbestos cement or lead is filled into the socket, and rubber sealing ring is filled into the socket to make the socket have good flexibility and allow the pipe to move a little. Welding and connecting: the connection has the best strength and sealing performance, is suitable for various pipelines, saves labor and materials, but the pipe and the pipe connector are required to be cut off when the pipe connector is disassembled.

It is now common to see interconnections between two pipes, and in both pipe joints, some sealing assemblies are used to maintain the tightness of the pipe joints, but these sealing assemblies are usually quite cumbersome to install and remove, so a mechanical seal that is easy to use is designed to solve this problem.
