Abstract
The utility model discloses a rapid joint, which comprises a seat consisting of a joint body A and a joint body B. The rapid joint is characterized in that an outer sleeve is added on the joint body A, a spring is arranged between the joint body A and the outer sleeve; a valve core is installed inside the seat; and springs are respectively arranged among two ends of the valve core and the inner wall of the seat corresponding to the valve core. The rapid joint is capable of effectively solving the problem of liquid leakage caused by the sealing failure of a conventional miniature tube joint, and lowering replacement frequency.
Description
Technical field
The utility model relates to a kind of transition head, relates in particular to a kind of rapid pipe joint.
Background technique
The transit joint of the high pressure hose of reality usefulness comprises major joint and male connector, and adapter body is provided with the cloudy interface that is connected with the male connector seal ring, adopts fixed by nut between male connector and the negative joint, and is relatively simple for structure.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.
The utility model is finished like this, construct a kind of rapid pipe joint, comprise the pedestal that constitutes by fittings body A and fittings body B, it is characterized in that: increasing on fittings body A has overcoat, between fittings body A and overcoat, be provided with spring, wherein spool is installed, between the base vivo wall corresponding of the two ends of spool, is provided with spring respectively with it in pedestal inside.
According to a kind of rapid pipe joint described in the utility model, it is characterized in that: fittings body A inwall is provided with back-up ring, is provided with spring ring between overcoat and fittings body B.
According to a kind of rapid pipe joint described in the utility model, it is characterized in that: in fittings body B, be provided with O shape circle, and between fittings body A and fittings body B, be provided with steel ball.
It is simple in structure in a kind of rapid pipe joint described in the utility model, can improve the connection reliability of pipe-line system connection mouth greatly.When the seal ring place has liquid to release, leakage liquid will arrive the space between two seal rings, and be taken away by vacuum pump by vacuum lead, thereby prevent that effectively liquid from leaking from seal ring.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: the 1-back-up ring; 2-fittings body A; The 3-spring; The 4-spool; 5-O shape circle; The 6-overcoat; The 7-spring; The 8-steel ball; The 9-spring ring.
Embodiment
Below in conjunction with accompanying drawing the utility model is explained:
As shown in Figure 1: a kind of rapid pipe joint, comprise the pedestal that constitutes by fittings body A 2 and fittings body B10, on fittings body A 2, increase overcoat 6 is arranged, between fittings body A 2 and overcoat 6, be provided with spring 7, wherein spool 4 is installed, between the base vivo wall corresponding of the two ends of spool 4, is provided with spring 3 respectively with it in pedestal inside.Fittings body A 2 inwalls are provided with back-up ring 1, are provided with spring ring 9 between overcoat 6 and fittings body B10.In fittings body B 10, be provided with O shape circle 5, and between fittings body A 2 and fittings body B 10, be provided with steel ball 8.It is simple in structure in a kind of rapid pipe joint described in the utility model, can improve the connection reliability of pipe-line system connection mouth greatly.When the seal ring place has liquid to release, leakage liquid will arrive the space between two seal rings, and be taken away by vacuum pump by vacuum lead, thereby prevent that effectively liquid from leaking from seal ring.
