Description
Technical field the utility model relates to the joint, particularly rapid pipe joint that a kind of pipeline connects usefulness.
Background technique is present, the kind of rapid pipe joint is many, the rapid pipe joint basic structure of generally using on the market is as follows: its main casing is made up of two sections different pipes of the diameter that is connected as a single entity, establish screw thread in this main casing large diameter tube free end, its outside thread with fixed tube joint one end is connected, and this fixed tube joint the other end is established adapter.Establish spring in this fixed tube joint, its front end is stuck in behind the plug set in the main casing large diameter tube on the prism.This plug is formed by the cylinder at middle part and its both sides are prismatic, and the preceding prism of this plug can insert in the seal ring that is located at the interior shaft shoulder place of main casing, and the cylinder end face of plug contacts with the seal ring face.Establish 3-4 shaft orientation opening groove on the above-mentioned main casing narrow tube, establish opening radial groove on the outer surface again, establish back-up ring in the groove near the end top of pipe.Establish the through hole of interruption on the narrow tube of radial groove inboard, it is built-in with positioning ball.Be with spring outside the main casing narrow tube, the one end is stuck on the outer shaft shoulder of main casing, and the other end is stuck on the interior projection of snap ring.This can with main casing narrow tube, spring, steel ball, and the snap ring main body that contains of back-up ring be annulus, establish 3-4 the projection that can be positioned at main casing narrow tube upper shed groove and move within it near the end in it, one side of these projections is provided with spring, and opposite side then is stuck on the back-up ring.Can insert the adapter of moving pipe joint in the main casing narrow tube, establish when the pipe plug is inserted into steel ball on it and enter radial groove in it, this adapter front-end face can contact with the seal ring end face.Its deficiency is: its connection or the sealing when disconnecting all are to be realized by a seal ring, seal ring is fragile, moving simultaneously pipe joint front end in use for some time, can cause envelope gas or water shutoff not tight because of wearing and tearing make its end face and seal ring face the space occur, shortening product working life.
The summary of the invention the purpose of this utility model is to provide the gas liquid two purpose rapid pipe joint of a kind of good seal performance, long service life.
The utility model is based on existing rapid pipe joint, mainly is to set up the seal ring A corresponding with the shaft shoulder in the main casing on the cylinder of plug, again former seal ring B is moved to simultaneously in the groove near the narrow tube of the interior shaft shoulder, and corresponding with the pipe joint adapter.
Main casing of the present utility model also is made up of two sections different pipes of the diameter that is connected as a single entity, and establishes screw thread in this main casing large diameter tube free end, and it can directly be connected with the outside thread of fixed tube joint one end, also can link to each other indirectly by a transition piece.This fixed tube joint the other end is established the adapter that can link to each other with connected tube, and it can have multiple structural type, if any the intubate of single-stage or multistage conehead, and male-pipe, or the intubate peripheral hardware is threaded in the lock ring ring on the pipe joint.In the fixed tube joint or the anterior rear end that is provided with spring, the front end of this spring is stuck in behind the plug on the prism.This plug that is located in the main casing large diameter tube is also formed by the cylinder at middle part and its both sides are prismatic, but establish radial groove on this plug cylinder, establish seal ring A in it, the sealing circle is corresponding with the shaft shoulder in the main casing, and it can be sealed sealing fluid when being used for rapid pipe joint and disconnecting.Also establish 3-4 shaft orientation opening groove on the above-mentioned main casing narrow tube, establish opening radial groove on the outer surface again, establish back-up ring in the groove near the end top of pipe.Establish the through hole of interruption on the narrow tube of radial groove inboard, it is built-in with positioning ball.Be with spring outside the main casing narrow tube, the one end is stuck on the outer shaft shoulder of main casing, and the other end is stuck on the interior projection of snap ring.This snap ring main body is an annulus, establishes the projection that number is corresponding with main casing narrow tube upper shed groove and can move within it near the end in it, and a side of these projections is provided with spring, and opposite side then is stuck on the back-up ring.Establish radial groove near interior shaft shoulder place in addition in the main casing narrow tube, establish seal ring B in the groove, can insert the adapter of moving pipe joint in it, the side of this adapter contacts and seals with seal ring B, sealing fluid when being used for the rapid pipe joint connection.When the pipe plug is inserted into, hold positioning ball and enter radial groove in it also being provided with in the adapter of above-mentioned moving pipe joint.The other end that should moving pipe joint is established the adapter that can link to each other with connected tube, and adapter is the same also multiple structural type can with another for it.
During use, the pipe that an end fixed, that move two pipe joints is connected with two needs respectively links to each other.When moving pipe joint does not inject rapid pipe joint, be pushed to shaft shoulder place in the main casing under the spring action of plug in main casing, seal ring A card is thereon with the fluid-tight in the fixed tube joint.When moving pipe joint injects rapid pipe joint, the seal ring B in the main casing is passed in its adapter, the side of taking over contacts with seal ring will move pipe joint opening and extraneous sealing, taking over to hold to push up then to contact with prism before the plug passes through fluid to pusher, when the steel ball card on the main casing minor diameter is in the radial groove that moving pipe joint is taken over, pipe joint promptly is inserted into the position, the position that steel ball will move pipe joint and main casing limits, two continuous pipe successful connections, tube fluid can pass through smoothly.The utility model can adopt metal to make, and also can adopt nonmetal making.
The utility model compared with prior art has following advantage:
1 use is efficient and convenient.
2 good seal performance.
3 long service life.
4 these structures can adopt non-metallic material, and it is not only corrosion-resistant but also cost is low.
