Abstract
A drain pipe joint and a drain pipe connection structure relate to a novel pipeline connection structure. The drain pipe joint and the drain pipe connection structure comprise a left flange joint and a right flange joint which can be cooperatively used in pairs with the left flange joint. The left flange joint shares a same structure with the right flange joint. Bolt connecting holes which are used for fastening and connection are formed in a flange plate of the left flange joint and the right flange joint. The drain pipe joint and the drain pipe connection structure are characterized in that the flange joints are steel, at least one annular melting layer is covered in advance on the outside surface of the straight pipe of the flange joints, the melting layer can melt by heating and polyethylene (PE) pre- coated lacquer is painted on the surface of the flange structure. Joint strength of flange structure and the drain pipe can be improved through heating. The heating is easy to operate and suitable for spot operation. The drain pipe and pipe material adopt a sealing connection through a rubber sealing gasket, which enables the construction to be convenient, fast and greatly reduces labor intensity and cost of pipe fittings.
Description
Technical field
The utility model relates to a kind of pipe coupling, specifically a kind of drain connection.
Background technique
Present drainage pipe can be divided into from configuration aspects: outer surface has the spiral winding pipe, plain-wall pipe of spiral reinforcing rod etc., and this drainage pipe uses complicated Placement to connect in the process of laying because bore is larger usually, prevents from leaking.The Placement of drainage pipe commonly used is that connection is connected in sweat soldering with steel now, and the join strength of sweat soldering wherein is lower, and steel is pricked the complicated structure of Placement, need to repeatedly carry out water-proofing treating, and cost is higher.
The model utility content
For a change the complicated the purpose of this utility model of existing Placement is to provide a kind of drain connection, is a kind of structure that is easy to install assembling, improves field erected efficient and quality.
The technical scheme in the invention for solving the technical problem is: a kind of drain connection, comprise the left and right sides flanged joint that is used in conjunction with in pairs, described left and right sides flanged joint structure is identical, flange plate at described left and right sides flanged joint has bolt connecting hole, be used for being fastenedly connected, it is characterized in that, described flanged joint is Steel Work, and at the pre-coated melting layer that is stamped at least one road annular of the straight tube outer surface of flanged joint, mode by heating is so that melting layer melts, and the existence of described melting layer can improve the adhesive strength of flanged joint and the pipeline that is connected.
Described melting layer is the PE coating layer that forms by applying, and has the characteristic that heating is easily melted.
Straight tube surface at flanged joint corresponding to described melting layer is provided with annular groove, is used for the storage fused materials.
Flange plate both sides at described flanged joint are provided with stiffening rib.
Use the connection structure for drain-pipe of this kind drain connection, it is characterized in that, be provided with rubber gasket between the flanged joint of the described left and right sides, the cross section of described rubber gasket is I shape, and is fastenedly connected by bolt between two flanged joints.
The beneficial effects of the utility model are:
1, flanged joint is steel component, and the characteristics of this structure are the large raisings of resistance to compression grade at tube connector place.
2, the flange arrangement surface scribbles the pre-coating of PE in factory, and the mode by heating can improve the adhesive strength with drainage pipe, and is easy and simple to handle, is fit to execute-in-place.
3, drainage pipe adopts rubber gasket to be connected and sealed with being connected of tubing, and easy construction is quick, has reduced widely labor intensity and pipe fitting cost.

Among the figure: 1 flange plate, 11 bolt connecting holes, 2 straight tubes, 3 stiffening ribs, 4 melting layers, 5 rubber gaskets, 6 waste pipes.
Embodiment
Embodiment one
Such as Fig. 1～shown in Figure 6, a kind of drain connection comprises the left and right sides flanged joint that is used in conjunction with in pairs, and left and right sides flanged joint structure is identical, be the stainless steel product or through antiseptic steel member, have bolt connecting hole 11 at the flange plate of left and right sides flanged joint.
Flanged joint is Steel Work, comprises flange plate 1 and straight tube 2, is provided with stiffening rib 3 in the flange plate both sides of flanged joint, can improve the intensity of flange plate.At the pre-coated melting layer 4 that is stamped three road annulars of the straight tube outer surface of flanged joint, this melting layer 4 is the PE coating layers that form by applying, straight tube surface at flanged joint corresponding to described melting layer is provided with annular groove, is used for the storage fused materials, so the straight tube outer surface is smooth.Melting layer 4 has the characteristic that heating is easily melted, and can carry out good being tightly connected with the drainage pipe in the outside by heating.The existence of this melting layer can improve the combination seal effect of flanged joint and the pipeline that is connected.
During connection, be provided with rubber gasket 5 between described left and right sides flange connects, the cross section of described rubber gasket is I shape, is stuck between two flanged joints, forms sealing effect, the generation of the phenomenon of avoiding seeping water.
Installation process is, at first the straight length with flanged joint inserts in the drainage pipe, then by hot weld so that waste pipe 6 connect with flanged joint, electric heating flange joint is so that melting layer 4 thawings, and waste pipe and flanged joint further carry out combination, uses at last bolt that adjacent flange plate is connected and get final product.
Embodiment two
Be with embodiment's one difference, the outer surface at flanged joint straight tube place applies one deck melting layer fully.
Except the described technical characteristics of specification, be the known technology of those skilled in the art.
Claims (5)
