Abstract
The utility model discloses a quick coupler nozzle, which comprises a female coupler and a male coupler. Two sealing rings are arranged between the contact surfaces of the female coupler and the male coupler. The sealed space formed between the two sealing rings is connected with a vacuum pump through an evacuation pipe. In order to facilitate the attachment of the female coupler and the male coupler, a quick coupling mechanism is additionally arranged between the female coupler and the male coupler. In order to judge the liquid leakage rate, a vacuum pressure gauge is additionally arranged between the evacuation pipe and the vacuum pump. The structure of the anti-leak pipe coupler is simple and the coupling reliability of the piping system coupling port is greatly improved. In case of liquid leakage at the sealing rings, the leaked liquid flows into the space between the two sealing rings and is evacuated by the vacuum pump through the evacuation pipe. Thereby, the liquid leakage from the sealing rings is effectively avoided.
Description
Technical field
The utility model relates to a kind of transition head, relates in particular to a kind of transit joint of high pressure hose.
Background technique
The transit joint of the high pressure hose of reality usefulness comprises major joint and male connector 2, and adapter body is provided with the cloudy interface 1 that is connected with male connector 2 seal rings, adopts nut 5 fixing, relatively simple for structure between male connector 2 and the negative joint 1.But along with the increase of diameter, whole transition interface is done the pressure that can bear and is obviously reduced, increase behind certain size even can't use, and poor safety performance.
The model utility content
The utility model has solved the technological method that above-mentioned technical problem adopted: it can effectively overcome conventional miniature valve joint because the leakage problem that seal failure produces reduces and changes frequency.
Described anti-leak pipe joint comprises negative and positive two joints, it is characterized in that: two seal rings sealings is arranged between the surface of contact of negative and positive two joints, and the seal space that forms between two seal rings is connected with vacuum pump by the pipeline of finding time.
The combination of male and female connector also is provided with the structure of meeting sb. at the airport soon between male and female connector for convenience.
Anti-leak pipeline structure described in the utility model is simple, can improve the connection reliability of pipe-line system connection mouth greatly.When the seal ring place has liquid to release, let out leakage liquid and will arrive space between two seal rings, and taken away by vacuum pump, thereby prevent that effectively liquid from leaking from seal ring by vacuum lead.
