Abstract
The utility model relates to a loose joint for pipes, which is used for connecting pipelines, particularly tap water supplying pipelines. The loose joint is provided with only one part, namely a connecting sleeve whose inner part is provided with threads and seal grooves. Compared with the loose joints greatly used at present, the utility model has the characteristics of simple structure, small size, low manufacturing cost, convenient installation, simple pipeline installation procedure and reliable sealing performance. The utility model can endure pressure change in a relatively wide range, and can be widely used in the installation and the connection of various hydraulic and pneumatic pipelines.
Description
The utility model relates to a kind of pipeline that is used for and connects, especially is applicable to 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 in piping erection, union is widely adopted, but existing union (as shown in Figure 4) is made of two joints and locking swivel nut, its boundary dimension is big, structure is also complicated, and two joints link with docking pipeline thread respectively, also need keep the gap of certain precision between the joint, therefore, install also and bother, in notification number is the Chinese patent of GG87200335, announce an a kind of movable pipe joint that not be used in connected pipe end processing silk mouthful, brought convenience to installation, but this movable pipe joint two ends all have been provided with attachment cap, lining and seal ring, the structure of itself are still complicated.
Task of the present utility model is to avoid above-mentioned deficiency and provides a kind of performance better movable pipe joint, and it not only is convenient to install, and the structure of self is also very simple.
The utility model is realized by following scheme: have one and connect cover 2, its difference is that an end has connecting thread 3 in connecing cover 2, and the other end is provided with seal groove 7, is equipped with seal ring 1 in the seal groove.
According to such scheme, the utility model is by being provided with screw thread and seal groove is realized in connecing cover, has only a part, therefore structure is simple especially, and its boundary dimension radially also greatly reduces, this helps the installation and the laying of pipeline, when two pipelines are connected, only need will connect cover 2 one ends and pipeline 8 screw threads and link, the other end pipeline 9 can directly insert, and do not need machining screw, the pipeline that inserts can connect to overlap and rotate, and the spacings between the two butt joint pipelines can have more error, these connection and installations to pipeline all can bring great convenience, and make the piping erection operation obtain simplifying.An end of the present utility model is provided with seal ring 1, owing to be static seal between it and the pipeline, seal ring can not wear and tear, so sealability also is very reliable, can bear variation in pressure in a big way.
Fig. 1 is an embodiment's of the utility model a positive view.
Fig. 2 is another embodiment's of the utility model a positive view.
Sectional view when Fig. 3 is connected with two pipelines for the utility model.
Fig. 4 is the half sectional view of existing union.
Embodiment of the present utility model such as Fig. 1, shown in 2, have one and connect cover 2, an end is provided with connecting thread 3 in connecing cover, screw thread can be straight thread or tapered thread, the other end can be provided with 1 road or 2 road sealing grooves 7 in connecing cover, be equipped with seal ring 1 in the seal groove, seal ring can be selected the O RunddichtringO for use, for the connection that makes two pipelines more firm, be provided with seal groove connect the cover one end also locking head can be set, locking head is by locking nut 5, the compression chuck 4 that has straight trough constitutes, locking nut 5 and compression chuck 4 are matched by tapered thread, in addition, and for ease of installing, on the outer ring that connects cover 2, can be provided with the tongue 6 of symmetry, the plane of two correspondences perhaps is set.
