Abstract
The utility model is a detachable connecting pipe fitting applied to pipe networks, such as direct drinking water pipe networks of municipal, industrial and civil buildings, etc., for delivering pressure fluid. The connecting piece comprises an adapter body (1), a terminal nut (2) and a clamp ring (3), wherein inner holes are formed on the adapter body (1) and the terminal nut (2) along the longitudinal centerline and used for containing a pipe (6); a groove (21) is formed at one end of the terminal nut (2) and used for containing the clamp ring (3); the end part of the groove (21) is connected with the adapter body(1); and the clamp ring (3) is clamped in a hermetic cavity circled by the adapter body (1) and the groove (21) arranged on the terminal nut (2). Since the structure in which connecting pipes are pressed tightly through the clamp ring clamped between the adapter body and the terminal nut to generate plastic deformation is adopted, the connecting pipe fitting has the advantages of simple structure, quick and reliable connection between pipes which do not need to be processed, convenient field installation and disassembly, reutilization, good pressure bearing effect and sealing effect.
Description
Technical field:
The utility model is that a kind of pipe networks such as municipal administration, industry, civil building direct drinking water that are applied to carry out the detachable connecting pipe fitting that pressure fluid is carried, and particularly a kind of stainless steel detachable connecting pipe fitting belongs to the renovation technique of detachable connecting pipe fitting.
Background technique:
The Placement of existing pipe fitting has varied, and commonly used have clamp-press type, compression type, push type, welding type and a various derivation Placement, and these Placements respectively have its characteristics and applicable situation.The clamp-press type Placement is that pipe arrangement is inserted pipe fitting, the U type groove of pipe fitting two ends for protruding, built-in seal ring, needing with the special pipe fitting instrument socket joint position card to be compressed into row connects, the advantage of this Placement is sealing joint reliable performance, easy construction, and shortcoming is can not reuse after interface cost height, the dismounting; The advantage of welding manner is the sealing joint reliable performance, but its shortcoming is can not reuse after interface cost height, the dismounting, and construction is inconvenient; The screw thread of thread connecting mode is to make in the roll extrusion mode to form, and its advantage is that interface cost is low, can reuse after the dismounting, easy construction, but that its shortcoming is a sealability is reliable inadequately.More than various Placements all can not accomplish that under the sealability reliable premise interface cost is low.Thereby make the pipe-networks engineering cost high, cause thin walled tube, particularly promoting the use of of stainless-steel thin-wall pipe is restricted.
The model utility content:
The purpose of this utility model is to consider the problems referred to above and provides a kind of connection reliable, good airproof performance, and is easy to field erected detachable connecting pipe fitting.The utility model is processed and is constructed simple and convenient.
The technical solution of the utility model is: include fittings body, Female connector fittings, clamp ring, wherein fittings body, Female connector fittings longitudinally center line all make the endoporus that holds tubing respectively, and an end of Female connector fittings is made the groove that holds clamp ring, the end of groove is connected with fittings body, and the clamp ring mounting board is in the closed cavity that fittings body and the set groove of Female connector fittings are surrounded.
The outside thread that the end of the set groove of above-mentioned Female connector fittings is made by the internal thread made on it and fittings body end spins.
Make the shoulder of the mounting point of fastening tubing on the inwall of above-mentioned fittings body.
The surface of contact of above-mentioned clamp ring and the set groove of Female connector fittings is last convex surface.
The shoulder and the surface of contact between the tubing of above-mentioned fittings body are provided with first seal ring.
The inwall and the surface of contact between the tubing of above-mentioned fittings body are provided with second seal ring.
The inwall of above-mentioned fittings body is made the groove that embeds second seal ring.
The utility model is owing to adopt the clamp ring by being clipped between fittings body and the Female connector fittings to produce the structure that plastic deformation compresses connection tubing, therefore, the utility model is simple in structure, tubing need not to carry out any processing, can realize quick between the pipe fitting, connection reliably, on-the-spot installation and removal are very convenient, and recyclable, and good pressure-bearing effect and sealing effect are arranged.The utility model is a kind of convenient and practical detachable connecting pipe fitting.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, include fittings body 1, Female connector fittings 2, clamp ring 3, wherein fittings body 1, Female connector fittings 2 longitudinally center line all make the endoporus that holds tubing 6 respectively, and an end of Female connector fittings 2 is made the groove 21 that holds clamp ring 3, the end of groove 21 is connected with fittings body 1, and clamp ring 3 mounting boards are in the closed cavity that fittings body 1 and Female connector fittings 2 set grooves 21 are surrounded.
In the present embodiment, for ease of processing and install, the outside thread that the end of above-mentioned Female connector fittings 2 set grooves 21 is made by the internal thread made on it and fittings body 1 end spins.
For ease of determining the mounting point of tubing 6, make the shoulder 11 of the mounting point of fastening tubing 6 on the inwall of above-mentioned fittings body 1.
Can produce the active force that acts in the clamp ring 3 when guaranteeing that Female connector fittings 2 is connected with fittings body 1, so that clamp ring 3 produces plastic deformation on direction perpendicular to axial direction and embedding is pressed into tubing 6, above-mentioned clamp ring 3 is last convex surface with the surface of contact 31 of Female connector fittings 2 set grooves 21.
For guaranteeing sealing, the shoulder 11 and the surface of contact between the tubing 6 of above-mentioned fittings body 1 are provided with first seal ring 5.Surface of contact between the inwall of above-mentioned fittings body 1 and the tubing 6 is provided with second seal ring 4.For ease of installing, the inwall of above-mentioned fittings body 1 is made the groove 12 that embeds second seal ring 4.
When the utility model engages in construction, fittings body 1 and Female connector fittings 2 are by being threaded togather, and in the tension process, clamp ring 3 produces plastic deformation on direction perpendicular to axial direction and embedding is pressed into tubing 6, form the firm engagement of pipe fitting and tubing, and produce good seal action.And when needs separate the pipe fitting dismounting, only need Female connector fittings 2 reverse back-outs are got final product, it is very convenient to adorn folding.
