Abstract
The utility model discloses an elastic cutting ferrule type pipe connecting head which comprises a connecting head body, wherein, the connecting head body is provided with outer screw threads, a compression nut is arranged outside the connecting head body, and a sealing ring is arranged in the connecting head body. The utility model is characterized in that the inner part of the connecting head body is provided with a bevel which is adjacent to the sealing ring, and the inner part of the connecting head body is also provided with a cutting ferrule ring. The utility model has the advantages that the structure is simple, the smoothness requirement of the pipe surface is low, firm connection is realized between the utility model and a pipe, the sealing property is good, and convenient and quick construction is realized. The utility model can be widely used in architecture decoration for civil pipe connection and in industry for oil, gas or water pipe connection.
Description
The utility model relates to the technical field of pipe joint, specifically a kind of elastic ferrule formula pipe joint that can connect fast.
Existing pipeline quick Connector coupling mainly is made up of fittings body, gland 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, pressurize or shake, if there is above situation can influence sealing effect between pipe and joints; 2, sealing effect is undesirable, and the tube outer wall that is connected not polishing also can influence the sealing effect of pipe coupling; 3, seal ring can only disposablely use.
The purpose of this utility model is to provide a kind of elastic ferrule formula pipe joint, can strengthen the soundness and the sealing effect at joint and pipe coupling place.
The technical solution of the utility model is achieved in that 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, be provided with an inclined-plane, a cutting ferrule circle also is housed in fittings body near the seal ring place.
The utility model is connected very firm with the pipe coupling place, sealability is good, it is easy to connect, rapid to construct, degree of finish to pipe surface is less demanding, pipeline be connected with 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 a structural representation of the present utility model
Fig. 2 is the structural representation of taking the cutting ferrule circle apart among Fig. 1
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises fittings body 5, on fittings body 5, be provided with outside thread, on clamping nut 2, be provided with the internal thread that matches with fittings body 5, the fittings body 5 outer clamping nuts 2 that are connected with, seal ring 4 is housed in fittings body 5, it is different from prior art: be provided with an inclined-plane 1. near seal ring 4 places in fittings body 5 a cutting ferrule circle 3 also is housed in fittings body 5, when screwing clamping nut 2, can make cutting ferrule circle 3 touch seal ring 4, seal ring 4 touches the inclined-plane in the fittings body 5 again, strengthen its soundness and sealing, the cutting ferrule circle 3 that is provided with in the present embodiment is approximate tapered, in clamping nut 2, can be provided with the inclined-plane 1 ' that matches with cutting ferrule circle 3, seal ring 4 is the soft elastic O-ring of rubber-like, can reduce degree of finish requirement to institute's connecting tube 6, further strengthen the soundness of fittings body 5 and pipe valve, sealing, the best oblique angle Q1 on the inclined-plane 1 that is provided with in fittings body 5 is 30-60 °, the best oblique angle Q1 ' on the inclined-plane 1 ' that is provided with in clamping nut 2 is 20-45 °.This joint cuts pipe earlier when mounted by length, need outside pipe, not process screw thread, the tube end that cuts is put clamping nut, metal taper cutting ferrule circle, soft elastic seal ring, insert the fittings body inward turning then and press tight nut, make the direct apace close-coupled of pipeline and joint.The joint that this joint can be widely used in pipelines such as civil pipeline joint in the architectural decoration and the oil in the industry, gas, water connects.
Claims (2)
