Description
The utility model relates to gas cylinder and combustion gas tool interconnection technique field, particularly a kind of gas safe joiner.
Existing a kind of gas safe quick connector includes rubber cushion 1, plug screw 2, cylinder joint 5, plunger tip (I) (18) that is connected with steel cylinder and turriform spring 3, steel ball 4, the O-ring seal 6 that is positioned at plug screw 2 inner chambers; The rear portion also is provided with rapid pipe joint, this rapid pipe joint comprises fittings body 9, be located at steel ball 8 on the fittings body 9 and Steel Cable Baffle Ring 7, can move at fittings body 9 outer surfaces outer unlatching cover 17 and outer casing spring 15, on fittings body 9 inner tube surfaces, be provided with the interior top cover 14 that can relatively move and at the interior sleeve spring 12 of fittings body 9 inwalls, in fittings body 9 inner chambers, be provided with plunger tip (II) 11, at plunger tip (II) 11 middle parts seal rubber pad 13 is housed, plunger tip (I) 18 front ends contact with steel ball 4 spheres, and its side is provided with inlet hole 19; At plunger tip (II) 10 rear portions connecting sleeve and connecting screw are housed, so that be connected with the pressure regulation valve port of special use.The connector of this kind structure can only be connected with the pressure regulator valve of special use, be not suitable for existing just widely used gas pressure regulating valve, and the pressure regulator valve of this special use need be bought with connector, and pressure regulator valve originally have to be thrown aside, and this just causes unnecessary waste; In addition, when spool (I) and spool (II) are that the cylinder joint ear end face contacts with the seal rubber pad that is enclosed within plunger tip (II) when contacting, this is that metal contacts with rubber, its sealing is not ideal enough, reasons such as invar bottle inflation are after this connector separates, outside the cylinder joint ear end face is exposed to, impaired by hard thing bump easily, thus its sealability can seriously be destroyed.
The purpose of this utility model is the gas safe joiner that a kind of good seal performance is provided and is applicable to the universal gas pressure regulator valve.
The purpose of this utility model is achieved in that a kind of gas safe joiner, include the rubber cushion 1 that is connected with cylinder angle valve, plug screw 2, cylinder joint 5, plunger tip (I) 18 and be positioned at the turriform spring 3 of plug screw 2 inner chambers, steel ball 4, O-ring seal 6, also be provided with rapid pipe joint at the cylinder joint rear portion, this rapid pipe joint comprises fittings body 9, if steel ball thereon 8 and Steel Cable Baffle Ring 7, the outer unlatching cover 17 and the outer casing spring 15 that can move at fittings body 9 outer surfaces, on fittings body 9 inner tube surfaces, be provided with the interior top cover 14 and the interior sleeve spring 12 that can relatively move, in fittings body 9 inner chambers, be provided with plunger tip (II) 11, seal rubber pad 13 is equipped with at this plunger tip (II) 11 middle parts, plunger tip (I) 18 front ends contact with steel ball 4 spheres, its side is provided with inlet hole 19, be connected with tapped connecting sleeve 10 in fittings body 9 rear threads, this internal thread is threaded with universal gas pressure regulator valve valve port; Described cylinder joint 5 rearward end are socketed with protection gum cover 16.
Advantage of the present utility model is: 1. this joiner is applicable to now widely used gas pressure regulating valve, thereby has made things convenient for the user, has also avoided the unnecessary waste of user; 2. it is impaired to avoid the cylinder joint ear end face to be bumped effectively, and sealability is more superior.
Fig. 1 is the utility model structural representation.
By following embodiment the utility model is further elaborated.
Referring to shown in Figure 1, embodiment's gas safe of the utility model joiner partly is made up of cylinder joint part and quick-acting joint.Cylinder joint part is made up of rubber cushion 1, plug screw 2, cylinder joint 5, plunger tip (I) 18 and the turriform spring 3, the steel ball 4 that are positioned at plug screw 2 inner chambers, plug screw 2 and cylinder joint 5 interior contacts the end and is provided with seal ring 6 and contacts with steel ball 4 spheres, cylinder joint 5 rear cavity are set with plunger tip (I) 18, between cylinder joint 5 and the plunger tip (I) 18 Steel Cable Baffle Ring is housed, plunger tip (I) 18 front ends contact with steel ball 4 spheres, and plunger tip (I) 18 front end sides are evenly equipped with 4 inlet holes 19.Cylinder joint part directly be threaded with cylinder angle valve and fixing and angle valve on.Quick-acting joint part by fittings body 9, be located at steel ball 8 and Steel Cable Baffle Ring 7 on the fittings body 9, can form at outer unlatching cover 17 and outer casing spring 15, plunger tip (II) 11, interior sleeve spring 12 that fittings body 9 outer surfaces move.On fittings body 9 inner tube surfaces, be provided with the interior top cover 14 that can relatively move and, be provided with draw-in groove with steel ball 8 corresponding positions on the outer surface of cylinder joint 5 at the interior sleeve spring 12 of fittings body 9 inwalls.At plunger tip (II) 11 middle parts seal rubber pad 13 is housed, is socketed with protection gum cover 16 in cylinder joint 5 rearward end.Be connected with connecting sleeve 10 in fittings body 9 rear threads, these connecting sleeve 10 rear portions are provided with interior threaded hole, are connected with general gas pressure regulating valve valve port screw thread.
During use; be threaded fixing with the connecting sleeve 10 of quick-acting joint part general pressure regulator valve intake valve port; the pressure regulator valve air outlet is connected with the gas cooker suction tude by sebific duct; cylinder joint 5 is inserted in the quick-acting joint front portion; plunger tip (I) 18 and plunger tip (II) 11 are joined; top cover 14 and mobile backward in withstand cylinder joint 5 rear ends; and then sleeve spring 12 in the compression; when interior top cover 14 is recessed out steel ball 8; and the draw-in groove on the cylinder joint 5 is when being in the corresponding position of steel ball 8; the outer cover 17 of opening moves forward under the elastic force effect of outer casing spring 15; utilize jacket wall that steel ball 8 is compressed into draw-in groove; the outer cover 17 of opening moves forward to when being blocked by Steel Cable Baffle Ring and stops, and like this, cylinder joint 5 just is connected together with the fittings body 9 of quick-acting joint part; at this moment; plunger tip (I) 18 front ends back down steel ball 4, and be positioned at cylinder joint 5 the protection gum cover 16 of end just tightly push down seal rubber pad 13, reach good seal action.Combustion gas in the steel cylinder successfully flows to the pressure regulator valve suction port under sealing condition.
Need the quick-acting joint part is partly unloaded when separating from cylinder joint, slightly firmly draw back as long as will open cover 17 outward, just realize resilient separation immediately, its inner body mechanism is opposite during with joint.
