Abstract
The utility model discloses a gas meter pipe joint which comprises a pipe body, a screw connection end and a nut connection end. An adjustable corrugated pipe is arranged in the middle section of the pipe body, a pressing nut is arranged at connection end of the nut, a convex edge matched with the pressing nut is arranged on the outer wall of the nut connection end, and a seal ring is arranged between the pressing nut and the convex edge. According to the gas meter pipe joint, due to the fact that the corrugated pipe is arranged in the middle section of the pipe body, the central positions of the thread connection end and the nut connection end can be adjusted through curving of the corrugated pipe, and the pipeline is easily aligned to a central hole of the gas meter pipe joint during installation. The gas meter pipe joint is rapid to install and good in installation quality, stress of the pipeline after installation is removed by curving radius of the corrugated pipe, the gas leakage cannot be caused, the seal ring is arranged between the pressing nut and the convex edge, and seal performance after installation is ensured.
Description
Technical field
The utility model relates to a kind of pipe fitting joint, relates in particular to a kind of gas meter pipe joint.
Background technique
At present, the general straight connector of adopting the loose joint of two bands of natural gas table is installed, there is following defective when mounted easily, the center of pipeline tracheae and the center of gas meter joint are difficult for suiting the medicine to the illness, make effort, time-consuming is installed, and because the effect of the eccentric internal stress in back is installed, make the pipe joint distortion easily and the phenomenon that leaks air impacts safety.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of gas meter pipe joint of being convenient to install, can guarantee installation quality.
The technical solution of the utility model is: a kind of gas meter pipe joint, comprise body, screw rod connecting end and nut connecting end, the stage casing of described body is adjustable bellows, described nut connecting end is equipped with gland nut, the outer wall of nut connecting end is provided with the convex edge with the gland nut coupling, is provided with seal ring between described gland nut and the convex edge.
As preferably, described seal ring is made by rubber.
The beneficial effects of the utility model are: because bellows is adopted in the stage casing of body, can regulate the central position of threaded ends and nut connecting end by the bending of bellows, be easy to make the center hole of pipeline and gas meter joint to align when mounted, installation is rapid, installation quality is good, the stress of back pipeline is installed is eliminated by the bending radius of bellows, can not produce the phenomenon of gas leakage; Be provided with seal ring between gland nut and the convex edge, the sealing after having guaranteed better to install.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, body; 2, gland nut; 3, convex edge; 4, seal ring.
Embodiment
As a kind of mode of execution of the present utility model, as shown in Figure 1, a kind of gas meter pipe joint, comprise body 1, screw rod connecting end and nut connecting end, the stage casing of described body 1 is adjustable bellows, and described nut connecting end is equipped with gland nut 2, and the outer wall of nut connecting end is provided with the convex edge 3 with gland nut 2 couplings, be provided with seal ring 4 between described gland nut 2 and the convex edge 3, described seal ring 4 is made by rubber.
The utility model is because bellows is adopted in the stage casing of body 1, can regulate the central position of threaded ends and nut connecting end by the bending of bellows, be easy to make the center hole of pipeline and gas meter joint to align when mounted, installation is rapid, installation quality is good, the stress of back pipeline is installed is eliminated by the bending radius of bellows, can not produce the phenomenon of gas leakage; Be provided with seal ring 4 between gland nut 2 and the convex edge 3, the sealing after having guaranteed better to install.
