Problems solved by technology
There are two ways of opening / closing the existing plugs: ⑴ There are mutually matching threads on the end of the container and the plug, screwed in / out manually, and then the plug is moved up / down the container. It is easy to damage the sealing surface on the plug when moving the plug, especially when the weight of the plug is heavy, it is more difficult to move; (2) There are no threads on the end of the container and the plug, and the hydraulic device is directly lifted and lowered Plug; this method will cause the equipment to be bulky, and the manufacturing cost will increase significantly. Due to the complexity of the equipment mechanism, the probability of failure will also increase.

The invention relates to a high-pressure container plug opening / closing device. The device comprises a bracket, a guide cover, a connecting rod, a hinge base and a rotating mechanism. The guide cover is arranged at the upper part of the bracket, and a high-pressure container is arranged at the bottom; a screw sleeve is arranged on the guide cover; a lead screw is arranged in the screw sleeve; a plug lifting wheel is arranged at the top end of the lead screw, and a plug is arranged at the bottom end of the lead screw; matched threads I are arranged at ports of the plug and the high-pressure container; a shaft hole is formed in the hinge base; a mandrel is arranged in the shaft hole; one end of the connecting rod is connected with the screw sleeve, and the other end is connected with the mandrel; and the rotating mechanism is arranged on the mandrel. The high-pressure container plug opening / closing device is simple and accurate in operation, is safe and reliable, can reduce the equipment manufacturing cost, and can prolong the service life.
Description
technical field [0001] The invention relates to the technical field of high-pressure containers, in particular to a plug opening / closing device for high-pressure containers. Background technique [0002] High-pressure vessels are used in scientific research and production in food processing, material manufacturing and other fields. High-pressure vessels need to withstand high pressure. When the volume of the vessel increases, the thickness of the metal sealing plug at the end needs to increase accordingly to meet the strength requirements. thereby increasing its weight. There are two ways of opening / closing the existing plugs: ⑴ There are mutually matching threads on the end of the container and the plug, screwed in / out manually, and then the plug is moved up / down the container. It is easy to damage the sealing surface on the plug when moving the plug, especially when the weight of the plug is heavy, it is more difficult to move; (2) There are no threads on the end of the c...
