Abstract
The utility model relates to a valve which is easy to make pipeline connection. A ring convex is arranged on the inner wall of a main body connecting joint of the valve, and an O-shaped seal ring is arranged on the ring convex; the only thing needing to do during the installation is to support a connecting pipe port on the seal ring, and the valve can be efficiently sealed on the pipeline. The utility model has the advantages that the installation and the maintenance are convenient, and the time and the labor force can be saved.
Description
The utility model relates to a kind of valve that easily connects on the pipeline that is installed in.
Existing valve, when mounted, for non-leakage between preventing valve and pipeline being threaded, do not emit water, on the pipeline inipple, twine raw meal belt usually, to improve the sealing between them, but operator are time-consuming when connecting, effort, make troubles for installation and maintenance.
Both quick and easy when the purpose of the utility model is to provide a kind of connection, the valve that can be connected with seal for pipe joints effectively again.Its technological scheme is such: it is equipped with " 0 " shape seal ring on the connecting head inwall of valve.As long as the connecting tube port is withstood on the seal ring, valve can be sealed on the pipeline effectively during installation.Because the utility model need not twine raw meal belt on pipeline, thus have when installing save time, laborsaving, installation, maintenance such as makes things convenient at advantage.
Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is Fig. 1 and partial enlarged drawing after pipeline is connected.
Referring to Fig. 1, Fig. 2, the utility model comprises valve body 3; It is protruding to be provided with circle at the not end of the two ends of this valve body 3 connecting head 1 inner thread, on this circle is protruding, be equipped with " 0 " shape seal ring 2, when connecting tube 4 is threaded with connecting head 1, stir valve body 3 or connecting tube 4, make connecting tube 4 top roof pressures on connecting head 1 seal ring 2, can reach the sealing between the link, thereby save the raw meal belt between the screw nipple 4.
Valve body 3 of the present utility model can be a ball valve, as Fig. 1, also can be plunger valve, other valve such as stop valve.
