Abstract
The utility model discloses an elastic cutting sleeve type pipe joint. The utility model is characterized in that the inner part of a joint body is provided with a bevel adjacent to a sealing ring; the inner part of the joint body is also provided with an open cutting sleeve ring and one to two sealing rings. Compared with the existing joint, the connecting point of the joint and a pipe is more firm, the sealing property is superior, the construction and connection are convenient and quick, and the requirement to the finish degree of pipe surface is not high. When the pipe is connected with the joint of the utility model, the sealing effect can not be affected by shocking, shaking, drawing, pressing, etc. from external force. By testing, the sealing pressure of the utility model in a hydraulic test can reach 3 MPa, the joint of the utility model is convenient for pipe maintenance and pipe disassembly, and the sealing rings can be used repeatedly.
Description
The utility model relates to the technical field of pipe joint, the specifically a kind of elastic ferrule formula pipe joint that can drop into fast.
Existing pipeline quick Connector coupling mainly is made up of fittings body, clamping nut and seal ring, there are the following problems for such pipe joint: 1, tightness is not enough after pipe and joint connection, can not the pipe that connect be shaken, draws, shake or pressurize, as and if above situation can influence sealing effect between pipe and joints; 2, sealing effect is not really desirable, the not bright and clean sealing effect that also can influence pipe coupling of the tube outer wall that is connected; 3, seal ring can only disposablely use.
The purpose of this utility model is to provide a kind of improved elastic ferrule formula pipe joint, and it can strengthen the soundness and the sealing of joint and pipe joint.
Metal scheme of the present utility model is achieved in that a kind of elastic ferrule formula pipe joint, it mainly comprises fittings body, on fittings body, be provided with outside thread, clamping nut is housed outside fittings body, seal ring is housed in fittings body, it is characterized in that: in fittings body, establish an inclined-plane, in fittings body, also adorn an open card lasso and 1-2 seal ring near the seal ring place.
The utility model is owing to also adorn an open card lasso and a seal ring in fittings body, it is more firm than existing with the joint of pipe, and sealability is good, and it is easy to connect rapid to construct, less demanding to the degree of finish of pipe surface; Pipeline be connected with this joint the back to the vibrations of external force, shake draw, pressurization etc. all can not influence sealing effect, the sealing load of its hydraulic pressure test can reach 3Mpa after tested, and this joint is all very convenient in maintenance, detaching pipelines to pipeline, and seal ring also can use repeatedly.
Fig. 1 is the utility model one embodiment's a structural representation
The schematic representation of Fig. 2 for preparing the utility model is installed
Fig. 3 is the schematic representation of the utility model installation in position
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises fittings body 6, on fittings body 6, be provided with outside thread, clamping nut 2 is housed outside fittings body 6, on clamping nut 2, be provided with the internal thread that matches with fittings body 6, seal ring 5 is housed in fittings body 6, it is different from prior art: establish an inclined-plane 1 near seal ring 5 places in fittings body 6, also adorn an elastic opening cutting ferrule circle 3 and 1-2 seal ring 4 in fittings body 6; The open card lasso 3 of present embodiment is approximate tapered or circular, open card lasso 3 can be fastening ring or elastic ring, 2 seal rings 4 are housed in fittings body, but one of them seal ring is opening also, in clamping nut 2, also be provided with the inclined-plane 1 ' that can match among the embodiment with open card lasso 3, screwing clamping nut 2 can make elastic opening cutting ferrule circle 3 touch seal ring 4, seal ring 4 touches the inclined-plane 1 in seal ring 5 and the fittings body 6 again, to strengthen soundness and sealing, seal ring 4 is the soft elastic O-ring of metal flat packing ring or rubber-like, can reduce degree of finish requirement, further strengthen the soundness of fittings body 6 and connecting tube 7 institute's connecting tube 7, sealing; The best oblique angle Q1 on the inclined-plane that is provided with in fittings body 6 is the 30-60 degree, and the best oblique angle Q1 ' on the inclined-plane 1 ' that is provided with in clamping nut 2 is the 20-45 degree.This joint cuts connecting tube earlier when mounted by length, need outside connecting tube, not process screw thread, the pipeline end that cuts is put clamping nut, elastic opening cutting ferrule circle, metal flat packing ring, soft elasticity O-ring seals, insert the fittings body inward turning then and press tight nut, pipeline directly closely is connected apace with joint, and the joint that this joint can be widely used in pipelines such as civil pipeline joint in the building decoration and the oil in the industry, gas, water connects.
Claims (3)
