Description
Technical field
The utility model relates to a kind of pipe joint, and specifically, the utility model relates to a kind of pipe joint, particularly a kind of quick-acting and quick-discharging joint for metallic hose pressure testing.
Background technique
Metallic hose is a kind of bearing pipe, and it is extensive application in industry and civilian equipment.As a kind of compression-member, before dispatching from the factory, MANUFACTURER must be carried out in accordance with regulations testing property, in order to eliminating reject.The structure that outreaches at small diameter metal flexible pipe two ends is male thread pipe joints, first connects and shutoff with supporting female joint during pressure testing, can carry out pressure test after two ends pipe joint seals completely.Although this kind of screw connection structure is very simple, it is also easy to connect, and sealing is reliable, meets pressure testing requirement completely.But every root metallic hose pressure testing process all obtains the female joint first screwing on two ends, oppositely unscrews again and lay down female joint after pressure testing, need to make multipurpose rotary because being threaded and could realize handling.This time, operation consuming timely about needed 5 ~ 8 minutes, and actual pressure testing only needs 3 ~ 6 minutes, owing to being greater than pressure testing man-hour unproductive time, caused pressure testing work efficiency low.Only applicable small lot batch manufacture is supporting for the action pressure-testing joint of this conventional structure, is not suitable for production in enormous quantities supporting.In addition, when metallic hose is with prior art pressure testing, because the male thread joint at two ends is directly sealed and matched with female joint, certainty leave over vestige in cooperation place, and this kind of defect damages the brand-new quality of commodity.
Model utility content
The utility model is rotatably connected mainly for prior art and consumes many deficiency unproductive time, proposes a kind of quick-acting and quick-discharging joint being specifically designed to metallic hose pressure testing, and this joint structure is simple, it is convenient to connect, sealing is reliable.
The utility model is achieved through the following technical solutions technical goal.
For the quick-acting and quick-discharging joint of metallic hose pressure testing, divide and be located at workpiece two ends oral area, it comprises plug, seal ring, clip and circle cover.Described plug is the stop bit plug that one end is axially arranged with shoulder, the reduced diameter section of plug and workpiece oral area endoporus Spielpassung, sealing configuration is formed between the two by the seal ring of setting-in, the plug being positioned at workpiece entrance point is provided with axial hole, this through hole introduces pressure source through externally connected pipe, and the plug being positioned at workpiece end oral area is solid plug.Its improvements are: described clip is made up of two identical semicircular collar, to the clip of opening structure coordinating by two ends inner edge axial limiting plug and workpiece.Described circle cover is thin-wall sleeve, and outer being enclosed within clip outer wall of circle cover makes to keep cooperation situation, removes round cover and is convenient to clip disintegration and dismantles plug.
In said structure, the major diameter limit of described plug and the outer male half coupling equal diameters of workpiece.Axial distance between the inner edge of described clip two ends, equals the plug exterior edge face male half coupling exterior edge face length dimension outside workpiece be on mounting point.
The utility model compared with prior art, has following good effect:
1, yoke configurations is simple, handling are easy, and consume only 2 ~ 3 seconds unproductive time during actual use, manufacturing efficiency is high;
2, during pressurization, plug is contained in the plug pressurized at workpiece two ends and moves outside axis, and the end thrust of formation strengthens the sealing of clip and plug junction plane further;
3, do not use the screw thread at workpiece two ends in pressure testing process, guarantee the brand-new quality of workpiece.

Fig. 1 is the utility model structural profile schematic diagram.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural representation of half clip in Fig. 1.
Fig. 4 is the left pseudosection of Fig. 3.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings below.
Embodiment illustrated in fig. 1 is quick-acting and quick-discharging joint for metallic hose pressure testing, and this joint divides and is located at workpiece 5 two ends oral area, and it comprises plug 1, seal ring 2, clip 3 and circle cover 4.Described plug 1 is axially arranged with the stop bit plug of shoulder for one end, and the reduced diameter section of plug 1 and workpiece 5 oral area endoporus Spielpassung, form sealing configuration by the seal ring 2 be inlaid in plug 1 reduced diameter section outer wall circular groove between the two.Divide the plug 1 being located at workpiece 5 two ends because of position difference, function is also not quite similar, therefore structure slightly difference.The plug 1 being positioned at workpiece 5 left end oral area in Fig. 1 is provided with axial hole, and this through hole introduces pressure source through externally connected pipe 1.1.The plug 1 being positioned at workpiece 5 right-hand member oral area in Fig. 1 is solid plug, and in pressure testing process, it only plays the effect of blocking workpiece 5 one end.Described clip 3 is the core components realizing quick-acting and quick-discharging, and it is made up of two identical semicircular collar as shown in Figure 3, Figure 4, clip 3 two ends of opening structure has been filled in the plug 1 of workpiece 5 oral area respectively by two ends inner edge screens.Axial distance between the inner edge of clip 3 two ends, equals the plug 1 exterior edge face workpiece 5 outer male half coupling 5.1 exterior edge face length dimension be apart on mounting point, makes plug 1 and workpiece 5 oral area inner hole position determine after clip 3 is in place.Described round cover 4 is thin-wall sleeve, endoporus and clip 3 outer wall Spielpassung.During pressure testing, treat that plug 1 and clip 3 are in place, then will be enclosed within clip 3 outer wall outside circle cover 4, utilize circle cover 4 radial direction to restraint clip 3, to keep the mounting point of clip 3 and plug 1.This structure is when pressure testing, and interior pressure acts on plug 1 interior edge face and forms end thrust, and end thrust strengthens the sealing of clip 3 and plug 1 junction plane further.Pressure testing is complete, then remove round cover 4 from clip 3 outer wall, and the clip 3 losing radial constraint is shattered into two halves, pulls out plug 1 and namely completes dismounting.More than installation and removal do not have rotary motion, easy and simple to handle, quick, and do not need any instrument.Whole charge and discharge operations does not have relative rotary motion, and the ripe refining operator on post installs or removes at every turn and only needed for 2 ~ 3 seconds, saves the time over half than prior art.This kind of quick-acting and quick-discharging structure, except manufacturing efficiency height, be the more important thing is that pressure testing does not use workpiece 5 two ends screw thread, is guaranteed the brand-new quality of commodity.
