Abstract
The utility model relates to a pipe joint for the central heating, comprising the main body of the joint (5), a pressing nut (6) and a sealing washer (7). The pipes (8) to be connected are directly extended into the main body of the joint, and the sealing washer is extruded by the pressing nut, which achieves the action of making the pipes sealed and fixed. Compared with the common pipe joint, the pipe joint for the central heating reduces the quantity of parts and can save the cast-iron by 25-30%. In addition, the pipes to be connected and the main body of the joint don't adopt the threaded connection, and therefore, the pipe joint for the central heating has lower requirement for the length size of the pipes and convenient installation.
Description
The utility model belongs to pipe-line system, especially the link in the water heating system.
At present, in the hot-water heating pipe-line system, the general Placement of pipeline is to connect by taking over transition, and required part is more, takes material, when taking a lot of work.Chinese patent 87207919 model utilitys have been simplified joint (seeing accompanying drawing 1), its working principle is that adapter body (1) links to each other with the radiator that will be connected, transition connecting tube (4) links to each other with adapter body and seals by gland nut (2) and seal washer (3).But four parts of still needing are formed, and cost is higher, and are threaded with the water pipe employing, and are tighter to the length size requirement of pipe when mounted, difficult during installation.
The purpose of this utility model is the less pipe coupling of a kind of part of development, to reduce material and expenditure of time, reduces cost.
Formation of the present utility model is the cancellation connecting tube, and water pipe directly links to each other with adapter body and seals by seal washer.
The structure of 2 explanations pipe coupling of the present utility model is as follows in conjunction with the accompanying drawings:
This joint is made up of adapter body (5) and gland nut (6) seal washer (7), there is screw thread at adapter body (5) two ends, one end links to each other with radiator, the other end and gland nut (6) match, and at inside placement seal washer (7), the pipe that connect (8) passes seal washer and gland nut stretches in the adapter body, tightens gland nut, make the seal washer distortion, seal.
The utility model has the advantages that and reduced part number,, can save cast iron 25--30% approximately so but economical with materials and save man-hour is compared with existing pipe coupling, in addition, directly insert in the adapter body because of connecting pipe, utilize frictional force to fix, need not be threaded, so when mounted, tube length is not had strict requirement, the surplus of freely stretching is arranged, easy for installation.
Embodiment of the present utility model is as follows:
When connecting radiator and intake pipe with pipe coupling of the present utility model, adapter body (5) links to each other with radiator by its outside thread.The other end of adapter body has outside thread and gland nut (6) to match, its internal diameter with want the water pipe connecting external diameter to match, 40 °~45 ° inclined-planes are fallen in the end, when tightening gland nut, because the effect on two inclined-planes seal washer extrusion-deformation, is played seal action.

Claims (2)
1, a kind of plumbing pipe joint, form by adapter body, seal washer, gland nut, it is characterized in that water pipe directly links to each other with adapter body, and seal by seal washer, there is outside thread at said adapter body two ends, one end links to each other with the radiator that will be connected, its interior edge face of the other end is the inclined-plane, inside is installed seal washer and is matched with gland nut, the pipe that connects passes seal washer and gland nut, in the insertion adapter body, compress seal washer, with fixing tube and sealing by gland nut.
2, by the said pipe coupling of claim 1, the inclined-plane that it is characterized in that adapter body one end is 40 °~45 °, and the gland nut interior edge face is 40 °~45 °.
