Cylinder cover locking mechanism for vertical pressure container

Abstract

The invention discloses a cylinder cover locking mechanism for a vertical pressure container. The cylinder cover locking mechanism includes a cylinder body and a cylinder cover, the bottom of the cylinder cover abuts against the top of the cylinder body, a piston cylinder is fixedly connected to the top of the outer side of the cylinder body, a first piston is slidably connected to the inside of the piston cylinder, a pull rod is fixedly connected to the top of the first piston, the top end of the pull rod penetrates through the top of the piston cylinder and extends to the outside of the piston cylinder, and a pre-compression spring is arranged at the position, located inside the piston cylinder, of the surface of the pull rod in a sleeving manner. The cylinder cover locking mechanism relates to the technical field of vertical pressure vessels. By means of the cylinder cover locking mechanism for the vertical pressure container, the pull rod is arranged to downwards pull a pressure ring, the rectangular pressure ring downwards presses the cylinder cover, and therefore the better sealing effect is achieved; and the pull-down action of the pull rod is realized through cooperation ofthe pre-compression spring and a ring pipe, the rectangular pressure ring can be controlled to pop up and retract back through cooperation of a permanent magnet coil and an electromagnet, operation is convenient and quick to realized, and manpower is saved.

Description

technical field [0001] The invention relates to the technical field of vertical pressure vessels, in particular to a cylinder cover locking mechanism for vertical pressure vessels. Background technique [0002] A pressure vessel is a closed device that holds gas or liquid and carries a certain pressure. In order to more effectively implement scientific management and safety supervision and inspection, my country's "Pressure Vessel Safety Supervision Regulations" divides pressure vessels into three categories according to working pressure, medium hazards and their role in production, and the pressure of each category Containers have different regulations in the design, manufacturing process, and inspection items, contents and methods. The pressure vessel has a wide range of uses, and it has an important position and role in many sectors such as industry, civil, military, and many fields of scientific research. Among them, the most used ones are in the chemical industry and t...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a cover locking mechanism for a vertical pressure vessel, which solves the problem that the cover of the existing pressure vessel is generally fastened to the cylinder body by using a bolt fastening structure or a buckle structure. The effect of sealing has been achieved, but for this kind of structure, in order to ensure the sealing, it needs to use a lot of force to fasten it, which is troublesome and laborious, and the simple sealing structure may loosen when the equipment is vibrated. And then will affect the sealing effect of the problem
