Abstract

The utility model relates to an externally sealing insertion type pipe joint. The externally sealing insertion type pipe joint is composed of a joint body (1), radial sealing rings (2), cushion rings (3), fastening devices (4), nuts (5), end surface sealing rings (6), and linings (7). The externally sealing insertion type pipe joint is characterized in that The linings (7), the end surface sealing rings (6), the radial sealing rings (2), the cushion rings (3), and the fastening devices (4) are respectively and orderly sheathed in two end heads of the joint body (1). The nuts (5) are respectively screwed on the two end heads of the joint body (1). The structure of the externally sealing insertion type pipe joint is simple. Aluminum-plastic composite pipelines can be simply strictly and firmly directly inserted and connected by the externally sealing insertion type pipe joint.

Description

External sealed type inserting type pipe joint
The utility model relates to a kind of external sealed type inserting type pipe joint, is a kind of dedicated pipe joint that is applicable in the aluminium-plastic composite pipe tube equipment.
At present, general pipe joint (as Fig. 1) belongs to interior sealed type, and the part of pipe joint is inserted internal diameter of the pipeline, and the interior hole path d of pipe joint increased fluid resistance, so flow loses slightly less than internal diameter of the pipeline D.
At present, general pipe joint (as Fig. 2) insertion portion has two annular grooves, and groove is embedded with two RUBBER O RunddichtringOs, 1/3rd protruding being exposed on the groove in sealing astragal footpath, easily cut away the protruding cushion rubber that reveals part sometimes at the otch Q place of pipeline end face during installation, the effect of influence sealing.
The purpose of this utility model is to design a kind of external sealed type inserting type pipe joint, to overcome the deficiencies in the prior art.
The purpose of this utility model is to realize like this, it is made up of fittings body (1), radial direction seal ring (2), packing ring (3), fastener (4), nut (5), end-face seal ring (6) and lining (7), it is characterized in that: be set with lining (7), end-face seal ring (6), radial direction seal ring (2), packing ring (3) and fastener (4) in the two ends of fittings body (1) respectively successively, screwed nut (5) on the two ends of fittings body (1) respectively.
Its feature also is: described fittings body (1) diameter of bore and pipeline (8) internal diameter measure-alike.
Its feature also is: described end-face seal ring (6) is the elastic ring that a section is the U font.
Its feature also is: described fastener (4) is that edge is gradient, the open annular circle of band claw-like tooth.
The utility model compared with prior art, it is simple in structure, can be simple and direct, tightly, securely plastic-aluminum combined pipeline is directly inserted connection.The utility model pipe joint belongs to the external sealed type, in the pipeline insertion tube joint, because the internal diameter of pipeline equates that with pipe joint endoporus channel diameter so runner does not have resistance, flow is not suffered a loss.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is existing current nipple assembly structure figure.
Fig. 2 is existing current nipple assembly state diagram.
Fig. 3 is the utility model mounting structure schematic representation.
Wherein: 1, fittings body, 2, radial direction seal ring, 3, packing ring, 4, fastener, 5, nut, 6, end-face seal ring, 7, lining, 8, pipeline.
Referring to accompanying drawing 3: it is made up of the utility model fittings body 1, radial direction seal ring 2, packing ring 3, fastener 4, nut 5, end-face seal ring 6 and lining 7, described fittings body 1 diameter of bore and pipeline 8 internal diameters measure-alike.Described end-face seal ring 6 is elastic rings that a section is the U font.Described fastener 4 is that edge is gradient, the open annular circle of band claw-like tooth.Be set with lining 7, end-face seal ring 6, radial direction seal ring 2, packing ring 3 and fastener 4 in the two ends of fittings body 1 respectively successively, screwed nut 5 on the two ends of fittings body 1 respectively.
During use, insert in the end of fittings bodies 1 overlapping loading nut 5, fastener 4, packing ring 3 and radial direction seal ring 2 backs successively on the outer circumferential face of suit end-face seal ring 6 and lining 7, pipeline 8 successively on the termination of pipeline 8, and nut 5 and fittings body 1 are screwed fastening getting final product.

Claims (4)

1, a kind of external sealed type inserting type pipe joint, it is made up of fittings body (1), radial direction seal ring (2), packing ring (3), fastener (4), nut (5), end-face seal ring (6) and lining (7), it is characterized in that: be set with lining (7), end-face seal ring (6), radial direction seal ring (2), packing ring (3) and fastener (4) in the two ends of fittings body (1) respectively successively, screwed nut (5) on the two ends of fittings body (1) respectively.
