Description
The utility model relates to gas cylinder and combustion gas tool interconnection technique field, particularly a kind of gas safe quick connector.
Existing a kind of gas safe coupling partly is made up of cylinder joint part and fast joint.Cylinder joint part is made up of rubber cushion, plug screw, cylinder joint, plunger tip (I) and the turriform spring, the steel ball that are positioned at the plug screw inner chamber, plug screw and cylinder joint interior contacts the end and is provided with sealing ring and contacts with the steel ball sphere, the cylinder joint rear cavity is set with plunger tip (I), plunger tip (I) front end contacts with the steel ball sphere, and plunger tip (I) front end side is evenly equipped with 4 air admission holes.The cylinder joint part directly is threaded with cylinder angle valve and is fixed on the angle valve.Fast joint part by fittings body, be located at steel ball and elastic spring on the fittings body, can form at outer unlatching cover and outer casing spring, plunger tip (II), interior sleeve spring that the fittings body outer surface moves.On the fittings body inner tube surface, be provided with the interior top cover that can relatively move and, be provided with draw-in groove with the corresponding position of steel ball on the outer surface of cylinder joint at the interior sleeve spring of fittings body inwall.At plunger tip (II) middle part seal gasket is housed, is socketed with the protection gum cover in the cylinder joint rearward end.Be connected with adapter sleeve in the fittings body rear threads, this adapter sleeve rear portion is provided with internal thread hole, is connected with general gas pressure regulating valve valve port screw thread.
During use, be threaded fixing with the adapter sleeve of fast joint part general pressure regulator valve intake valve port, the pressure regulator valve gas outlet is connected with the gas-cooker air inlet pipe by sebific duct, cylinder joint is inserted in the fast joint front portion, plunger tip (I) and plunger tip (II) are joined, top cover and mobile backward in withstand the cylinder joint rear end, and then sleeve spring in the compression, when interior top cover is recessed out steel ball, and the draw-in groove on the cylinder joint is when being in the correspondence position of steel ball, and outer the unlatching moves forward under the elastic force effect that is enclosed within outer casing spring, utilizes jacket wall that steel ball is compressed into draw-in groove, the outer cover of opening moves forward to when being blocked by elastic spring and stops, like this, the fittings body of cylinder joint and fast joint part just is connected together, at this moment, plunger tip (I) front end backs down steel ball, has connected fuel gas path.There is following weak point in the gas safe coupling of said structure: sealing property is relatively poor, and gas leak phenomenon can take place.Because the seal gasket of the protection gum cover of cylinder joint rearmost end and adapter sleeve front end is the plane contact compression seal, adapter sleeve is long heavier in addition, can swing, and causes loose contact, and also fatiguability of rubber, thus seal unreliable.Simultaneously also can cause fast joint part insertion force big, inconvenient operation.
The purpose of this utility model is to provide a kind of light, that sealing property is fabulous and gas safe quick connector that be applicable to the universal gas pressure regulator valve swift to operate.
The purpose of this utility model is achieved in that a kind of gas safe quick connector, include the rubber cushion 1 that is connected with cylinder angle valve, plug screw 2, cylinder joint 3, and the turriform spring 4 that is positioned at plug screw 2 inner chambers, copper sphere 5, O-ring seal 6, also be provided with snap joint at cylinder joint 3 rear portions, this snap joint comprises fittings body 10, if steel ball thereon 7 and elastic spring 17, the outer unlatching cover 8 and the outer casing spring 9 that can move at fittings body 10 outer surfaces, on fittings body 10 inner tube surfaces, be provided with the interior top cover 15 and the interior sleeve spring 14 that can relatively move, be provided with the plunger tip 13 of band center roof vent in adapter sleeve 11 front end central authorities, these plunger tip 13 front ends contact with copper sphere 5 spheres, its side is provided with air admission hole 18, be connected with tapped adapter sleeve 11 in fittings body 10 rear threads, this internal thread is threaded with universal gas pressure regulator valve valve port, and described plunger tip 13 middle front parts and cylinder joint 3 are slidingly matched and parallelly on the face are provided with three O shape rubber seal 16; Described copper sphere 5 front portions are cylinder, and the thin end of turriform spring is enclosed within on this cylinder.
Advantage of the present utility model is good seal performance, safe and reliable; Adapter sleeve inserts with dial-out all light, flexible.
Fig. 1 is the structural representation of an embodiment of the utility model.
By following embodiment the utility model is further elaborated.
Referring to shown in Figure 1, an embodiment gas safe of the utility model quick connector, include the rubber cushion 1 that is connected with cylinder angle valve, plug screw 2, cylinder joint 3, at plug screw 2 inner chambers turriform spring 4 is housed, copper sphere 5, O-ring seal 6, also be provided with snap joint at cylinder joint 3 rear portions, it comprises fittings body 10, if steel ball thereon 7 and elastic spring 17, the outer unlatching cover 8 and the outer casing spring 9 that can move at fittings body 10 outer surfaces, on fittings body 10 inner tube surfaces, be provided with the interior top cover 15 and the interior sleeve spring 14 that can relatively move, in fittings body 10 inner chambers, be provided with the plunger tip 13 of band center roof vent, these plunger tip 13 front ends contact with copper sphere 5 spheres, its side is provided with four air admission holes 18, plunger tip 13 rearward end are threaded with adapter sleeve 11 leading sections, and with rubber seal 12 sealing, be connected with tapped adapter sleeve 11 in fittings body 10 rear threads, this internal thread is threaded with universal gas pressure regulator valve valve port.For the enhanced leaktightness performance, guarantee its safety, reliable, for this reason, parallelly on plunger tip 13 middle front parts and cylinder joint 3 are slidingly matched face be provided with three O shape rubber seal 16.For make the copper sphere 5 and the sphere of plunger tip 13 front ends connect accurately, quick, thereby copper sphere 5 front portions are designed to cylinder, the thin end of turriform spring 4 is enclosed within on this cylinder.
During use, be threaded fixing with the adapter sleeve 11 of snap joint general pressure regulator valve intake valve port, the pressure regulator valve gas outlet is connected with the gas-cooker air inlet pipe by sebific duct, cylinder joint 3 rear portions are inserted in snap joint, top cover 15 and mobile backward in withstand cylinder joint 3 rear ends, and then sleeve spring 14 in the compression, when interior top cover 15 is recessed out steel ball 7, and when the draw-in groove on the cylinder joint 3 is in the correspondence position of steel ball 7, the outer cover 8 of opening moves forward under the elastic force effect of outer casing spring 9, utilize jacket wall that steel ball 7 is compressed into draw-in groove, the outer cover 8 of opening moves forward to when being blocked by elastic spring and stops, like this, cylinder joint 3 just is connected together with fittings body 10, at this moment, plunger tip 13 front ends back down copper sphere 5, and the combustion gas in the steel cylinder is successfully flowing to the pressure regulator valve air inlet under the sealing condition all around.
Need the fast joint part is partly separated when unloading from cylinder joint, slightly firmly draw back as long as will open cover 8 outward, just realize resilient separation immediately, its inner body course of work is opposite during with joint.
