Abstract
The utility model relates to a pipe connecting device. The utility model is composed of a pipe member and a connecting member which are mutually connected, wherein, the middle part of the inner side of the pipe member is provided with threads, and both ends of the connecting member are hollow pipes with outer threads. The connecting member is embedded in the pipe member by the threads. The middle part of the outer side of the connecting member is provided with a clamping part or a clamping cover, and a sealing ring is fixed on the outward end of the clamping part of the clamping cover. Another sealing ring is fixed between the clamping cover and the inner threads of the pipe member. The utility model treats connection and sealing separately, and two connecting methods are used together, so the connecting reliability is high, and the sealing property is good. In addition, the utility model has the advantages of simple structure, and convenient implement and operation.
Description
(1) technical field
The utility model relates to the pipe fitting technical field that is applied in the pipeline connection, specifically is meant a kind of assembling pipe joint.
(2) background technique
At present, in the pipe-line system that thin-wall metal plastic lining composite pipe is formed, adopt pipe fitting to connect between the pipeline, Placement has mechanical compression type (comprising FERRULETYPE, clamp-press type etc.) connection to be connected with direct bonding or braze welding type.The deficiency of these modes is: the connection power that has not enough (as mechanical clamp-press type etc.), and the poor sealing that has (as directly bonding), the difficulty of construction that has is big to need complicated construction facility and skilled worker's (being connected as braze welding type).
(3) summary of the invention
The utility model is exactly in order to solve above-mentioned the deficiencies in the prior art part, provide a kind of connections reliably, good airproof performance and implement assembling pipe joint easily.
A kind of assembling pipe joint described in the utility model, it is characterized in that, it is interconnected by pipe fitting and link forms, wherein, the pipe fitting middle inside has screw thread, and link is the externally threaded hollow tube of two ends band, embeds in the pipe fitting by screw thread, the outer middle side part of link has screens or card cover, is fixed with seal ring in screens or the outside end of card cover.Between card cover and pipe fitting internal thread, also be fixed with seal ring.
The utility model is in pipeline connects, and connecting and sealing processing respectively, tubing is realized being connected by internal thread and pipe fitting, seal ring is compressed form end seal and radial seal, and the fluid in the pipe can not leaked at body and tubing joint.Connect better and sealing effect for reaching, can add alite paste at the tubing and the outside, pipe fitting joint.
The utility model compared with prior art has following advantage and beneficial effect:
1. the utility model is connecting and sealing processing respectively, and two kinds connect actings in conjunction, make to connect reliability height, good airproof performance.
2. the utility model is simple in structure, and is convenient on the implementation and operation.
(4) description of drawings
Fig. 1 is the utility model embodiment one a structural representation;
Fig. 2 is the utility model embodiment two a structural representation.
(5) embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment one
As shown in Figure 1, pipe fitting 4 middle inside have internal thread 5, and link 2 is the hollow tube of two ends band outside thread 7, embed in the pipe fitting 4 by screw thread, and link 2 outer middle side parts have screens 6, are fixed with seal ring 3 at screens 6 outside ends.Tubing 1 is the ultra-thin-wall plastic stainless-steel composite-tubes, is connected with link 2 and pipe fitting 4 by internal thread.Seal ring 3 adopts O type rubber ring, and the sealing between tubing 1 and the pipe fitting 4 realizes by O type rubber ring.Seal ring 3 is between link 2 and tubing 1 screw thread, and the inwall of pipe end through being squeezed in tubing 1 and link 2 forms end and radial seal respectively, makes between tubing 1 and the pipe fitting 4 and does not produce leakage.The internal thread of tubing 1 processes with special screw tap, processes when the internal thread 5 of pipe fitting 4 is injection moulding.As mentioned above, can realize the utility model preferably.
Embodiment two
As shown in Figure 2, link 2 outer middle side parts have card cover 9, are fixed with seal ring 3 at card cover 9 outside ends, also are fixed with seal ring 8 between card cover 9 and pipe fitting 4 internal threads.Tubing 1 is that outer wall is to be not easy to bonding plastic tube (as PPR pipe) outerly to be the tubing of plastics (as aluminium-plastic composite pipe, its skin is the PE material) with metal composite.Blocking cover 9 is thin metal coverings, can be pressed together on the plastic outer layer of tubing 1 with the mode of roll extrusion, makes between its outer wall and the pipe fitting 4 and can be bonded together with viscose glue, with seal ring 3 sealings, is sealed by seal ring 8 between link 2 and the pipe fitting 4 between tubing 1 and the link 2.All the other structural principles are identical with embodiment one.As mentioned above, can realize the utility model preferably.
Claims (2)
1. assembling pipe joint, it is characterized in that, it is interconnected by pipe fitting and link forms, wherein, the pipe fitting middle inside has screw thread, and link is the externally threaded hollow tube of two ends band, embeds in the pipe fitting by screw thread, the outer middle side part of link has screens or card cover, is fixed with seal ring in screens or the outside end of card cover.
2. a kind of assembling pipe joint according to claim 1 is characterized in that, also is fixed with seal ring between card cover and pipe fitting internal thread.
