Abstract
The utility model relates to a water heating pipe in the class of hardware, particularly a convenient pipe joint. A body of the convenient pipe joint is provided with at least two interfaces, wherein the interface sections of the body are provided with internal screw threads, wherein the internal diameter of a transition section between the end of the internal threads and the body is in the shape of a cylinder, and the transition of the diameter change part of the internal diameter of the transition section between the interface sections of the body and the body is performed by a sealing step. When the convenient pipe joint is connected with a pipe, sealing connection is realized by a sealing ring which is previously arranged on the sealing step. The convenient pipe joint has the advantages of good sealing effect, simple and fast connection mode, no need of traditional tools, such as box spanners, etc. and manual screwing.
Description
Technical field:
The hot-water heating pipe fitting of the utility model design five metals class, particularly a kind of portable type pipe fitting joint.
Background technique:
Common pipe fitting joint all is threaded with other pipe fittings employings by the internal thread of its interface, internal thread had both risen and had screwed interconnect function, seal again, but pipe fitting belongs to rigid components, be subjected to the restriction of processing technology again, the sealing that is threaded is relatively poor, for this reason, general screwing with pipe fitting joint again after the spiral shell of pipe fitting is buckled the winding raw meal belt or the rope made of hemp is connected, though improved sealing effect, but this method wastes time and energy, and inconvenience is installed.
Summary of the invention:
Goal of the invention of the present utility model provide a kind of easy for installation fast, good airproof performance, long-lived portable type pipe fitting joint.
The technological scheme that realizes the foregoing invention purpose is: have two interfaces at least on this portable type pipe fitting joint body, the interface section of this body has internal thread, its internal diameter of changeover portion from this inside body of this female ends is cylinder type, and the internal diameter reducing place of the interface section of this body and the changeover portion of this body is by the sealed step transition.When this pipe fitting joint is connected with pipe fitting, realize being tightly connected by the seal ring that is placed on sealing step place in advance.
Portable type pipe fitting joint according to this technological scheme realization, when being connected with pipe fitting, owing to realize sealing by prepositioned seal ring, twine the raw meal belt or the rope made of hemp again and needn't buckle at the spiral shell of pipe fitting, therefore, good sealing effect, and Placement simple and fast, even do not need traditional instruments such as pipe lead, only screw by hand and get final product.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.This embodiment is a pipe fitting joint that is called pipe nipple, this joint has two interfaces 1, the interface section 2 of this body has internal thread 3, changeover portion 4 its internal diameters from this inside body of these internal thread 3 ends are cylinder type, and the interface section 2 of this body is passed through sealed step 5 transition with the internal diameter reducing place of the changeover portion 4 of this body.When this pipe fitting joint is connected with pipe fitting, realize being tightly connected by the seal ring that is placed on sealing step 5 places in advance.
Pipe fitting joint described in the utility model can also be pipe fitting joints such as elbow, threeway, four-way except that above-mentioned pipe nipple.
