Abstract

The invention discloses a corrosion-resisting quick coupling. The quick coupling comprises a fixing socket and a male plug matched with the fixing socket. A sealing component, a holder, a first elastic lantern ring and a pressing sleeve are arranged in the fixing socket from inside to outside in sequence. The pressing sleeve is fixedly connected with the fixing socket. A top cover is arranged in the pressing sleeve, and a through hole allowing the male plug to penetrate through is formed in the top cover axially. A plurality of first openings are uniformly distributed in the inner wall of thefirst elastic lantern ring in the circumferential direction, a plurality of second openings are uniformly distributed in the outer wall of the first elastic lantern ring in the circumferential direction, and the first openings and the second openings are formed in a staggered mode. The corrosion-resisting quick coupling is simple in structure and easy to implement; the coupling is quick and convenient to mount and dismount; and the first elastic lantern ring and a second elastic lantern ring are made of the stainless steel material, a pressing component and pressing sheets are made of the tetrafluorohydrazine material, the corrosion resistance of the coupling is improved, the service life of the coupling is prolonged, in addition, the production cost is low, and the quick coupling is easier to apply and popularize.

Description

technical field [0001] The invention relates to a pipeline connection device, in particular to a corrosion-resistant quick joint. Background technique [0002] In daily life and industrial production equipment, it is often necessary to connect and disassemble pipes. Pipes are devices connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles. In order to realize fast operation, various quick connection structures have been designed. However, rubber sealing rings are used inside the quick connection structure, which is not corrosion-resistant. For example, paint, banana water, etc. cannot be used. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a corrosion-resistant quick joint that is easy to install and disassemble. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invention is: [0005] A corrosion-res...
