Description
The utility model relates to gas cylinder and combustion gas tool interconnection technique field, particularly a kind of gas safe quick-acting connector.
Existing a kind of household liquified petroleum gas connects pressure governor soon, and it comprises pressure governor valve, cylinder angle valve joint and connects the two quick-acting joint.The cylinder angle valve joint comprises sealing gasket, plug screw pipe, cylinder joint, and valve core spring and steel ball and the rubber cushion of sealing the mouth of pipe are arranged in the plug screw pipe; The pressure governor valve comprises pressure governor valve body and plug pipe; Quick-acting joint comprises fittings body, the locking ball on fittings body and Steel Cable Baffle Ring, the outer unlatching cover and the outer casing spring that can move at the fittings body outer surface, and connecting sleeve is connected with the plug pipe; A plunger tip that can back down sealed steel ball in the plug screw pipe is housed in connecting sleeve, there is inlet hole this pipe end side, and this pipe middle part is set with seal rubber pad, on fittings body pipe face, have mobile in top cover and the interior sleeve spring on the connecting sleeve end face, with the corresponding position of locking ball draw-in groove is arranged on the outer surface of cylinder joint.During use, the cylinder angle valve joint has been connected on the cylinder for liquefied gas angle valve, the connecting sleeve of quick-acting joint and pressure governor valve the plug pipe be connected.When pressure regulator valve is connected with angle valve, as long as the fittings body front end is entangled cylinder joint, enforce fittings body forward, make the cylinder joint rear end prop up interior top cover, by interior sleeve spring, locking ball, draw-in groove, outer casing spring, Steel Cable Baffle Ring, the outer unlatching under the acting in conjunction of overlapping, locking ball in draw-in groove, thereby cylinder joint and fittings body are linked together.Desire with pressure governor when steel cylinder is dismantled, can retreat opening the power of applying mechanically outward, under interior sleeve spring, locking ball, interior top cover, cylinder joint, draw-in groove effect, cylinder joint withdraws from fittings body, steel ball is sealed in the plunger tip disengaging, and this steel ball is lived the plug screw pipe mouth of pipe at valve core spring effect lower seal.The existing deficiency of said structure is: 1, the cylinder joint ear end face contacts to metal contacts with rubber with the seal rubber pad at plunger tip middle part, and sealing is not ideal enough; After quick-acting connector separated, the cylinder joint ear end face was easily damaged, and has destroyed sealability.2, need special-purpose pressure governor valve port to be attached thereto and connect, can't be attached thereto for present widely used pressure regulator valve and connect use.
The purpose of this utility model is to provide a kind of simple in structure, good seal performance and is applicable to the gas safe quick-acting connector of universal gas pressure regulator valve.
The purpose of this utility model is achieved in that a kind of gas safe quick-acting connector, comprise cylinder joint part and quick-acting joint part, cylinder joint partly comprises rubber cushion (1), plug screw (2), cylinder joint (5) and turriform spring (3) steel ball (4) that is positioned at plug screw (2) inner chamber, O-ring seal (7), quick-acting joint partly comprises fittings body (9), if steel ball thereon (8) and Steel Cable Baffle Ring (6), the outer unlatching cover (16) and the outer casing spring (14) that can move at fittings body (9) outer surface, on fittings body (9) inner tube surface, be provided with the interior top that can relatively move and overlap (15) and interior sleeve spring (11), in fittings body (9) inner chamber, be provided with plunger tip (17), this plunger tip (17) mid-rear portion is equipped with seal rubber pad (12), and its front end contacts with steel ball (4) sphere, its sidewall is provided with inlet hole (18), and described cylinder joint (5) rearward end is socketed with protection gum cover (13); Be connected with the connecting sleeve (10) of being with interior threaded hole in fittings body (9) rear threads, this interior threaded hole is threaded with universal gas pressure regulator valve valve port.
Advantage of the present utility model is: 1, this quick-acting connector 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, after the quick-acting connector split, it is impaired to avoid the cylinder joint ear end face to be bumped effectively, thereby 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 quick-acting connector 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 and the turriform spring 3, the steel ball 4 that are positioned at plug screw 2 inner chambers, be provided with O-ring seal 7 between plug screw 2 rearward end and the cylinder joint 5, the cylinder joint part directly is threaded with cylinder angle valve and is fixed on the angle valve.Quick-acting joint part by fittings body 9, be located at steel ball 8 and Steel Cable Baffle Ring 6 on the fittings body 9, can form at outer unlatching cover 16 and outer casing spring 14, interior top cover 15, plunger tip 17, interior sleeve spring 11 and connecting sleeve 10 that fittings body 9 outer surfaces move.Be provided with the interior top cover 15 that can relatively move and at the interior sleeve spring 11 of fittings body 9 inwalls, plunger tip 17 front ends contact with steel ball 4 spheres on fittings body 9 inner tube surfaces, its anterior side is evenly equipped with 4 inlet holes 18, and with O-ring seal 7 endoporus Elastic Contact.Be provided with draw-in groove with steel ball 8 corresponding positions on the outer surface of cylinder joint 5.At plunger tip 17 rear portions seal rubber pad 12 is housed, is socketed with protection gum cover 13 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, make plunger tip 17 withstand steel ball 4, top cover 15 and mobile backward in withstand cylinder joint 5 rear ends, and then sleeve spring 11 in the compression, when interior top cover 15 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, and the outer cover 16 of opening moves forward under the elastic force effect of outer casing spring 14 when being blocked by Steel Cable Baffle Ring 6 and stops.Like this, cylinder joint 5 just is connected together with the fittings body 9 of quick-acting joint part, and at this moment, plunger tip 17 front ends back down steel ball 4, and its inlet hole 18 leaves O-ring seal 7, has been communicated with the combustion gas gas circuit.Meanwhile, the protection gum cover 13 that is positioned at cylinder joint 5 rear-most ends is just tightly pushed down seal rubber pad 12, reaches good seal action.Combustion gas in the steel cylinder successfully flows to the pressure regulator valve suction port under sealing state.When pneumatic inflation, this quick-acting connector will separate, and cylinder joint 5 rear ends will expose outside, because the protection of protection gum cover 13 is arranged, thus make cylinder joint 5 rearward end avoid damaging impaired, guaranteed sealing reliability.
When needing the quick-acting joint part partly separated with cylinder joint, slightly firmly draw back, just realize resilient separation immediately as long as will open cover 16 outward, its inner body mechanism with in conjunction with the time opposite.
