Abstract
A multi-layer sealing clamping sleeve type tube part used for the connection with metal tube consists of a metal tube part body, a sealing ring, a metal band and a screw cap. The sealing ring and a metal loop multi-sealing are formed after the utility model being connected and installed. The structure has advantages of easy and convenient installment and using, reliable sealing and long service life.
Description
The utility model is relevant with metal tube connection leakage proof, is meant that especially a kind of metal tube connects multi-layer sealed (flexible sealing body and rigid seal body) ferrule-type pipe fitting of usefulness.
The cutting ferrule pipe fitting of the metallic conduit of supply connection in the market because its connection easy construction is used widely, wherein relates to surface, the concealed installation concealed work of drinking water pipeline, heating pipe, refrigerant pipe.But, these metallic conduits connect with the cutting ferrule pipe fitting and often very easily produce percolating water phenomenon owing to construction wrong, if occur in the concealed installation concealed work then have endless trouble, not only the property management maintaining are made troubles, and have a strong impact on body of wall, floor, make property impaired.
The purpose of this utility model is to provide a kind of improved metal tube to connect the multi-layer sealed ferrule-type pipe fitting of usefulness, and this simple in structure being convenient to is produced in batches, and is easy to use, prevents the stable performance of seepage, long service life.
The purpose of this utility model is achieved in that
A kind of multi-layer sealed ferrule-type pipe fitting that is used for the metal tube connection, include metal pipe element and nut, it is characterized in that also having seal ring and metal ferrules, the appearance of described metal pipe element is divided three sections, the stage casing is the hexagonal plate body, about two sections be provided with outside thread, the bore of metal pipe element also is divided into three sections, the stage casing has less internal diameter, about two sections have bigger internal diameter, its joint respectively forms a ring-shaped step, left and right sides two-port is provided with chamfering, said nut is a hexagon nut, one end has the internal thread that matches with the outside thread of metal pipe element, and the other end is a tight mouthful of end, and the internal diameter of two sections bodys is suitable about its bore and described metal pipe element; Said seal ring is placed on the ring-shaped step place in the metal pipe element pipe, and metal ferrules when using be lock ring the metal tube that will connect outside and by the tight mouth of the port chamfering of metal pipe element and hexagon nut hold urge fastening.
Also be provided with second seal ring before the said metal ferrules.
The cross section of said metal ferrules is a crescent shape.
The cross section of said metal ferrules is trapezoidal.
Between the tight mouth end of said hexagon nut and the internal thread is the female cone chamber face of transition.
Said metal pipe element comprises copper pipe fitting, stainless steel pipe etc., and said seal ring comprises fluorine rubber, silicone rubber or separates seal ring or other flexible sealing colloids that sub-plastic or other material makes all can.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is that the user mode of the utility model most preferred embodiment is partly cutd open schematic representation.
Among the figure:
I.II---metal tube
1---the left and right body of metal pipe element 11---hexagonal plate body 12---
13---outside thread 14---ring-shaped step 15---chamferings
2---seal ring 3---seal ring 4---metal ferruless
5---hexagon nut 51---internal thread 52---female cone chamber faces
53---tight mouthful of end
See also Fig. 1.The most preferred embodiment of the multi-layer sealed ferrule-type pipe fitting of the utility model is by metal pipe element 1, hexagon nut 5, seal ring 2, seal ring 3 and metal ferrules 4 are formed, metal pipe element 1 is seen from appearance can regard three sections as, the stage casing is a hexagonal plate body 11, connect metal tube I for this pipe fitting, can utilize spanner and so on instrument application of force to establish during II, a left side, right two sections bodys 12 are provided with outside thread 13, the internal diameter of metal pipe element 1 also is divided into three sections, the stage casing has less internal diameter, and about two sections have bigger internal diameter, thereby its joint respectively forms a ring-shaped step 14, lay for seal ring 2, port is provided with chamfering 15; Said hexagon nut 5, its wide mouth part is provided with the internal thread 51 that matches with the outside thread 13 of metal pipe element 1, and the other end is a tight mouthful of end 53, and the internal diameter of the body 12 of its bore and metal pipe element 1 is suitable, also the external diameter with metal tube I that is connected or II is suitable, is convenient to penetrate into good.Said metal ferrules 4 lock rings are in the port appropriate location of the metal tube I that will connect, and said seal ring 3 is positioned at one side of metal ferrules 4 nearly metal tube I ports.
The multi-layer sealed ferrule-type pipe fitting of the utility model, can make all size size, usefulness for the metal tube that connects different bores, Fig. 1 has represented to connect the pipe fitting of the metal tube of identical bore, also can be made into left and right two sections metal pipe elements 1 with different bores, mix corresponding hexagon nut, for the metal tube that connects two different bores.
The using method of multi-layer sealed Bite type fittings of the present utility model is as follows:
1. metal tube to be connected is penetrated from 5 tight mouthfuls of ends 53 of hexagon nut;
2. metal ferrules 4 tightly is enclosed within the port appropriate location of the metal tube I that will connect, is inserted in seal ring 3 again;
3. put into seal ring 2 at ring-shaped step 14 places of metal pipe element 1;
4. metal tube I is inserted in the body 12 of metal pipe element 1, again hexagon nut 5 rotation sets on the outside thread 13 of metal pipe element 1, and screw with proper implements, promptly formed have seal ring 2, seal ring 3 is connected with the pipe of the multiple-sealed structure of metal ferrules 4;
In like manner, metal tube II can be connected with the other end of the multi-layer sealed ferrule-type pipe fitting of the utility model.
The advantage of the multi-layer sealed ferrule-type pipe fitting of the utility model is as follows:
1. it is multi-layer sealed to have seal ring 2, seal ring 3 and metal ferrules 4, thereby sealing is reliable;
2. easy to use, install and do not carry out other pipe fitting processing when connecting, as long as connect, do not need the know-how personnel by above-mentioned mode, can both make the metal tube that is connected non-leakage, and long service life.
3. simple in structure, be convenient to produce in enormous quantities, thereby will have favorable economic benefit and social benefit.
