Abstract
The invention relates to a dismountable pipe fitting applied to pipe networks for municipal, industrial, civil building direct drinking water, etc. in order to transport pressure fluid. The pipe fitting comprises a joint body (1), a joint nut (2) and a clamp ring (3), wherein the joint body (1) and the joint nut (2) are respectively provided with an inner hole holding pipes (6) along a longitudinal center line, and one end of the joint nut (2) is provided with a groove (21) holding the clamp ring (3); an end part of the groove (21) is connected with the joint body (1); the clamp ring (3) is clamped in a closed cavity surrounded by the joint body (1) and the groove (21) arranged on the joint nut (2). Adopting a structure of producing plastic deformation through the clamp ring clamped between the joint body and the joint nut so as to compress the connecting pipes, the pipe fitting is simple in structure, can realize the fast reliable connection of pipe fittings without carrying out any processing treatment to the pipe fitting, is very convenient for field installation and dismantlement, can be recycled, and has good pressure bearing and sealing effects.
Description
Technical field:
The present invention 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 pipe fitting two ends are the U type groove of protrusion; Built-in seal ring; Need with the special pipe fitting instrument socket joint position card to be compressed into row and connect, 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 with 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.
Summary of the invention:
The objective of the invention is to consider the problems referred to above and provide a kind of connection reliable, good airproof performance, and be easy to field erected detachable connecting pipe fitting.The present invention processes and constructs simple and convenient.
Technological scheme of the present invention 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 through 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 present invention is owing to adopt the clamp ring through being clipped between fittings body and the Female connector fittings to produce the structure that plastic deformation compresses connection tubing; Therefore, the present invention is simple in structure, and 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 present invention is a kind of convenient and practical detachable connecting pipe fitting.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
Embodiment:
Structural representation of the present invention is 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, and 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 through the internal thread made on it and fittings body 1 end spins.
For ease of confirming 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 on direction perpendicular to axial direction, produces plastic deformation 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 present invention engages in construction; Fittings body 1 is in the same place through being threaded with Female connector fittings 2, and in the tension process, clamp ring 3 on direction perpendicular to axial direction, produces plastic deformation 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.
