Abstract
The utility model relates to an active jointing head for a pipe for pipeline connection, particularly water supply pipeline connection. The active jointing head for a pipe is provided with a connecting sleeve. One end of the connecting sleeve is provided with a connecting screw, and the other end is patched with a telescopic connecting pipe and is provided with a sealing part. The other end of the telescopic connecting pipe is provided with a connected screws. The utility model has the advantages of simple structure, small appearance size, convenient use and installation, and reliable sealing performance. The active jointing head for a pipe is used in the connection and the butt-joint of the pipelines, which enables the installing process to be further simplified.
Description
The utility model relates to a kind of pipeline that is used for and connects, and particularly is suitable for the movable pipe joint that water supply pipe connects.
In the connection and butt joint of pipeline, use union can simplify and make things convenient for the installation procedure of pipeline, therefore, union is widely adopted in piping erection, and existing union is made of two joints and locking swivel nut, and its boundary dimension is big, structure is also complicated, and installs also than trouble.In application number is 91200880 Chinese patent, announced and a kind ofly connect that an end is provided with screw thread in the cover, the other end is provided with the movable pipe joint of seal groove, it have simple in structure, boundary dimension is little and the characteristic being convenient to install, but in actual use because the first end of loose joint is direct and the external diameter phase configuration of pipeline, thereby its sealability tends to be subjected to the influence of caliber tolerance and out of roundness, reduced its sealing reliability.
Task of the present utility model is to avoid above-mentioned deficiency and a kind of improved movable pipe joint is provided, and its not only simple in structure being convenient to is installed, and has reliable sealing performance.
The scheme that realizes the utility model task is as follows: have one and connect cover 5, connect cover one end and be provided with connecting thread 1, its difference is to have connected a flexible connecting tube 4 at the other end that connects cover 5, be provided with Sealing 2 at their mating face place, be provided with connecting thread 3 at the other end of flexible connecting tube 4.
According to such scheme, owing to set up a flexible connecting tube 4 to connecing cover 5, fit tolerance each other can be subjected to controlling preferably, avoided when directly pegging graft because of the influence of caliber tolerance and out of roundness its sealability with pipeline, make the utility model possess reliable sealing performance, the utility model has only two parts, its structure is still very simple, boundary dimension is also less, connecing cover 5 and individual contracting can relatively rotate and stretch between the connecting tube 4, therefore use to install still very conveniently, in the connection and butt joint of pipeline, its installation procedure is further simplified.
Fig. 1 is an embodiment's of the utility model a positive view.
Embodiment of the present utility model as shown in Figure 1, have one and connect cover 5, connect the interior end of cover and be provided with connecting thread 1, in connecing cover, connected a flexible connecting tube 4 in the hole of the other end, place, mating face in flexible connecting tube can be provided with an annular seal groove 6, install seal ring 2 in the seal groove and connect cover matched, seal groove and seal ring can be provided with the 1-2 road, seal groove and seal ring also can be arranged in the endoporus that connects cover 5, its effect is identical, the other end of flexible connecting tube 4 is provided with connecting thread 3, and the endoporus of flexible connecting tube is connected with the endoporus that connects cover, and flexible connecting tube 4 can be straight-through, also can be elbow bend or threeway cross fitting, in addition, for ease of installing, the backstop position 7 of both sides correspondence can be set also in the outside that connects cover 5 and flexible connecting tube 4,8.
