CN2251064Y - Combined jointing part for thin-wall pipe - Google Patents

Abstract

The utility model discloses a combined jointing part for thin-wall pipes, which is composed of thread sleeves which are screwed with each other, screw caps, a common liner bushing with a scapula and an O-shaped sealing ring which is arranged between the liner bushing scapula and a pipe flaring mouth. The utility model makes the pipe flaring mouth deform, press the O-shaped sealing ring and paste the liner bushing scapula through screwing down the thread sleeves and the screw caps for forming firm and sealed connection and solving the connection problem of thin-walled pipes. The utility model replaces galvanized pipes with stainless steel thin-wall pipes, eliminates the defects of original galvanized pipes, and has the advantages of long service life, light weight, beautiful appearance, neatness, etc.

Description

Thin walled tube combination fitting

The utility model relates to the connection set of thin walled tube.

Usually, wall thickness is called thin walled tube at the pipe below 1 millimeter, and thin walled tube is generally made with stainless steel or copper material, it is compared with traditional galvanized pipe, has not polluted water, can resist soda acid and other Korrosionsmedium advantage to corrosion of piping, and the iron rust that has fundamentally solved galvanizing pipe pollutes, therefore, the application of picture stainless steel and so on thin walled tube is more and more general, as indoor installations such as home dwellings is a kind of emerging tap water delivery pipe, and the trend that replaces galvanized pipe is gradually arranged.The application thing followed of thin walled tube is the technical problem that has produced the connection aspect, and the connection of galvanized pipe is usually being threaded, but on-the-spot machining screw needs equipment, and pretty troublesome, thin walled tube has its particularity, and thin should not the employing of wall is threaded; Also have a kind ofly to connect with swivel nut, nut, the sealing of " O " RunddichtringO, but also do not have a kind of desirable connection set at present.

The utility model provides a kind of at the existing in prior technology defective and is connected firmly, the thin walled tube of good airproof performance combination fitting.

Realize that the utility model is at the end of pipe suit to have externally threaded swivel nut, the end of another pipe suit have internal thread, with the swivel nut spiral shell by nut, and be provided with the lining of public band omoplate at the end of two pipes endoporus, two " O " RunddichtringO branches are located between lining omoplate and the two pipe enlargings, utilize swivel nut to produce axial displacement with the mutual spinning of nut and reach the purpose that is connected two thin walled tubes.

This combination fitting is with the support of lining as thin walled tube, two thin walled tubes after the connection can be out of shape not only have certain rigid but also have connectivity robustness and sealing preferably, solved the connectivity problem of thin walled tube, replace galvanized pipe with stainless steel thin-wall and do not need on-the-spot machining screw, eliminated water pollution that galvanized pipe caused because of iron rust pollutes and to corrosion of pipe, be used for the fluid line conveying that water supply pipe conveying and pressure are not higher than 1 MPa, long service life, in light weight, the size that takes up room, specious, clean and tidy.

Accompanying drawing 1 provides the utility model structural representation.

Be described in detail again below in conjunction with above-mentioned accompanying drawing embodiment.

As shown in Figure 1; thin walled tube combination fitting comprises a swivel nut (1), a nut (4); both are spirally connected mutually and are set in the thin walled tube end of two butt joints; be inserted in the lining (2) of public band omoplate in the thin walled tube, two " O " RunddichtringOs (3) divide and are located between lining omoplate and the two pipe enlargings.

Described thin walled tube comprises that wall thickness by stainless steel or copper material system is at the pipe below 1 millimeter.

Elder generation was enclosed within swivel nut and nut respectively the end of two thin walled tubes when this combination fitting used, then enlarging processing is carried out in the thin walled tube end, enlarging processing is carried out at the scene, technological method is simple and easy, the thin walled tube inner orifice is inserted at the lining two ends that will be set with two " O " RunddichtringOs more respectively, screw nut, swivel nut at last, the axial displacement that causes along with the screw-in length increase makes nut, swivel nut press to enlarging respectively, the distortion of enlarging tightly is attached on the omoplate of lining " O " RunddichtringO, and formation is connected firmly, the connection set of good airproof performance.Can be used for that straight tube is connected with straight tube, straight tube is connected with three-way pipe, bend pipe is connected or the like with three-way pipe, when being used for and joint (5) when being connected, this joint is equivalent to the effect of lining and swivel nut, and can omit lining and swivel nut this moment.

Claims (1)

1. part is pressed in a thin walled tube combination, at the end of pipe suit and to have externally threaded swivel nut (1), at the end of another pipe suit and to have nut (4) internal thread, that be spirally connected with swivel nut, also be provided with " O " RunddichtringO, it is characterized in that the end endoporus of two pipes is provided with the lining (2) of public band omoplate, two " O " RunddichtringOs (3) branch is located between lining omoplate and the two pipe enlargings.
