Abstract
A thin-wall connector of a stainless steel water pipe belongs to a connecting assembly of a water pipe. The utility model solves the problems and defects which are resulted from the easy leakage and the difficult maintenance of the existing thin-wall connector of the stainless steel water pipe. The thin-wall connector of stainless steel water pipe of the utility model comprises a middle connector, locking nuts and O-shaped sealing rings, wherein the middle connector is arranged at the connecting point of the water pipe, and the locking nuts and the O-shaped sealing rings are respectively arranged on the outer surfaces of both ends of the middle connector. The middle connector is provided with outer threads. Conical surfaces which are fit with the conicity of the connecting point of the water pipe are formed on the outer surfaces of the front and the back ends of the middle connector. O-shaped annular grooves are arranged on the conical surfaces of the middle connector, and the O-shaped sealing rings are arranged in the O-shaped annular grooves. The conicity is formed at the front ends of the locking nuts, which are fit with the conical surface of the connecting point of the water pipe.
Description
Technical field
The utility model relates to a kind of connection part of water pipe, particularly a kind of thin-wall stainless steel water pipe joint.
Background technique
In the building water supply piping, past, the metal galvanizing pipes that adopt sent water more, because of its polluted water, just progressively replaced by engineering plastics and plastic-aluminum combined water pipe, but this kind tubing is coming with some shortcomings in various degree also, can not satisfy the needs of water-feeding pipes system and country fully to potable water and relevant requirements in water quality thereof, so the Ministry of Construction issued " thin-wall stainless steel water pipe " industry standard in calendar year 2001, feed piping provides the more pipe fitting of high-quality.
In view of this, stainless steel thin-wall water pipe joint adopts clamp-press type and two kinds of methods of ring-type muscle compression type more, but all comes with some shortcomings at present, and is specific as follows:
(1) the clamp-press type joint adopts the pipeline inner and outer surface to be connected with joint inner and outer surface card press fit, but the stainless steel thin-wall water pipe in use, because manifold pressure size and temperature variation, original rigidity intensity produces sudden change, make pipeline junction loosening easily, seepage takes place, must repair by equipment special in maintenance, for example seepage is taken at the pipeline middle part needs a series of pipelines are reinstalled.
(2) ring-type muscle compression type joint adopts the pipe interior reaming to make the water pipe outer surface form convex surface and is connected with joint; Ring-type muscle convex surface because of leaving groove in its inside, because pipeline pressure size and variation of temperature make pipeline and joint linear telescopic, produces seepage, and easily produces dirt in the groove that ring-type muscle convex surface forms in using after compression in running.
The model utility content
The purpose of this utility model is to solve existing thin-wall stainless steel water pipe with joint easy to leak and problem and shortage that easy-maintaining did not produce, and a kind of good seal performance, thin-wall stainless steel water pipe joint simple in structure are provided.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: described thin-wall stainless steel water pipe comprises the transition joint that is arranged at the water pipe joint, is arranged at the locking nut and the O RunddichtringO of described transition joint two ends outer surface respectively with joint; Described transition joint is provided with outside thread, and the tapering that the outer surface in the transition joint rear and front end is formed with the conical surface and water pipe joint matches; The conical surface of described transition joint is provided with O type circular groove groove, and is provided with the O RunddichtringO in O type circular groove groove; The front end of described locking nut is formed with tapering and matches with the conical surface of water pipe joint.
Adopt said structure, by cooperatively interacting and be arranged at O RunddichtringO in the transition joint conical surface between each conical surface, make water pipe and transition joint realize that driving fit is connected, effectively avoided making between water pipe and joint loosening because of water pipe internal pressure and temperature variation, leakage problems takes place, and has improved the sealability of thin-wall stainless steel water pipe with joint.
Description of drawings
Fig. 1 is the structural representation of the utility model thin-wall stainless steel water pipe with joint;
Fig. 2 is the partial enlarged drawing at the O of being provided with RunddichtringO shown in Figure 1 position.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, the utility model thin-wall stainless steel water pipe comprises the transition joint 1 that is arranged at water pipe joint 2, is arranged at the locking nut 3 and the O RunddichtringO 4 of described transition joint 1 two ends outer surface respectively with joint; Described transition joint 1 is provided with outside thread, and the tapering that the outer surface in transition joint 1 rear and front end is formed with the conical surface and water pipe joint 2 matches; The conical surface of described transition joint 1 is provided with O type circular groove groove, and in O type circular groove groove, be provided with O RunddichtringO 4, by cooperatively interacting and be arranged at O RunddichtringO 4 in transition joint 1 conical surface between each conical surface, make water pipe realize that with transition joint 1 driving fit is connected, effectively avoided making water pipe and 1 of joint loosening because of water pipe internal pressure and temperature variation, leakage problems takes place, and has improved the sealability of thin-wall stainless steel water pipe with joint; The front end of described locking nut 3 is formed with tapering and matches with the conical surface of water pipe joint 2; By the outside thread that is arranged at transition joint 1 locking nut 3 is provided with thereon,, has realized that sealed against leakage possesses enough tensile strength simultaneously again in order to be one with O RunddichtringO 4 strong bonded with water pipe, transition joint 1.
Described O RunddichtringO 4 can adopt high strength health O type ring.
The front end of described locking nut 3 is conical, and the rear end is a hexagon or for excircle is provided with protruding stupefied muscle, these locking nut 3 internal surfaces have screw thread.
Do not guarantee promptly that for the flow that makes water does not change in the joint water-flowing amount is constant, make the transition joint 1 and the internal diameter of water pipe in full accord.
Above-mentioned embodiment is illustrated the utility model with preferred embodiment, but the example of this visualization of just lifting for the ease of understanding should not be considered to be the restriction to the utility model scope.Equally, according to the description of the technical solution of the utility model and preferred embodiment thereof, can make various possible being equal to and change or replacement, and all these changes or replacement all should belong to the protection domain of the utility model claim.
