Problems solved by technology
[0003] High-pressure cleaners are widely used in light industry, ship paint removal, sand removal in foundry industry, cement industry preheater crust removal, etc. The working pressure of high-pressure cleaners is usually 350-1600bar. The joints that play the role of connection have higher requirements. The joints provided by the prior art are mostly connected by friction between the joints and the water supply mechanism. Since the friction is related to the roughness of the contact surface and the normal pressure of the contact, when When the joint is repeatedly used and disassembled, the roughness of the contact surface between the joint and the water supply mechanism will gradually decrease, and at the same time, due to wear, the contact positive pressure between the joint and the water supply mechanism will also gradually decrease. The phenomenon that the joint and the water supply mechanism are often separated, not only is not conducive to production work, but also causes a lot of waste of water resources

The invention discloses a self-locking connector for conveying high-pressure liquid. The self-locking connector comprises a locking and connecting device, and the locking and connecting device comprises a supporting sleeve with the position arranged fixed, and a locking and sealing element arranged on the supporting sleeve. The locking and sealing element is used for achieving locking and unlocking between the supporting sleeve and a fluid extruding pipe and can be used for connecting with the fluid extruding pipe with external equipment. The locking and sealing element is hinged to a supporting section, and a hinge shaft core wire is consistent with the groove width direction of a containing groove. The locking and sealing element can be pushed to rotate around a hinge shaft to rotate andblock and open a flow guide hole. When the flow guide hole is opened, the locking and sealing element is in a locked state. The locking and sealing element comprises a locking section for cooperatingand locked with an annular groove in the fluid extruding pipe, and a sealing section for blocking and opening the flow guide hole, and a built-in step matched with an external step is formed at the joint of the locking section and the sealing section.
Description
[0001] This invention is a divisional application of the invention patent with the application date of November 15, 2017, the application number: 2017111303393, and the invention title of "self-locking interface for conveying high-pressure liquid". technical field [0002] The invention relates to a joint, in particular to a joint used in high-pressure liquid and gas butt joint transportation. Background technique [0003] High-pressure cleaners are widely used in light industry, ship paint removal, sand removal in foundry industry, cement industry preheater crust removal, etc. The working pressure of high-pressure cleaners is usually 350-1600bar. The joints that play the role of connection have higher requirements. The joints provided by the prior art are mostly connected by friction between the joints and the water supply mechanism.
