Abstract
The utility model discloses a metal rubber-plastic composite pipe cover composed of a pipeline, a screw cap, a metal cover, a rubber ring, and a pipe fitting body. The metal cover is sheathed on the pipeline. The rubber ring is positioned on the rear of the metal cover. The pipe fitting body is sheathed on the metal cover form rear. The screw cap is sheathed on the metal cover form front and is connected with a thread of the pipe fitting body. The utility model has the advantages of good sealing effect, wide range of application, etc. Because each component adopts identical materials, the coefficient of expansion is concord. Leakage phenomenon does not appear when the pipe fitting meets cold or heat or the impact of a water hammer. The metal rubber-plastic composite pipe cover is particularly suited for cold and hot water supply and water for fire fighting occasions.
Description
The utility model belongs to a kind of pipe fitting Sealing.
Thin-wall pipe under the situation of heat supply water, because the joint coefficient of thermal expansion and contraction is inconsistent, produces the infiltration phenomenon through regular meeting when using the self-locking sealed pipe fittings to connect at present.In addition, in fire-fighting water during emergency water supply impact of water hammer and when catching fire high-temperature baking pipe fitting and can causing supply water malfunctioning.
The purpose of this utility model is: a kind of pipe fitting big envelope of each parts expansion coefficient unanimity is provided, it can not leaked under above-mentioned various situations.
The utility model is to constitute like this: it is by pipeline (1), nut (2), metallic envelope (3), rubber ring (4), pipe fitting (5) is formed, and metallic envelope (3) is enclosed within on the pipeline (1), rubber ring (4) places the back of metallic envelope (3), pipe fitting (5) is enclosed within on the metallic envelope (3) from behind, and nut (2) is enclosed within on the metallic envelope (3) from the front, and is threaded with pipe fitting (5).
Advantages such as the utility model compared with prior art has good sealing effect, and is widely applicable.Because each parts adopts identical materials, its expansion coefficient unanimity is so water leakage phenomenon can not take place in pipe fitting when meeting cold reception heat and impact of water hammer.Being particularly suitable for hot and cold water water supply and fire-fighting water occasion uses.
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment of the present utility model: earlier metallic envelope (3) is enclosed within on the pipeline (1), put rubber ring (4) again, pipe fitting (5) is enclosed within on the metallic envelope (3) from behind, nut (2) is enclosed within on the metallic envelope (3) from the front, and the internal thread of nut (2) and pipe fitting (5) outside thread are tightened and got final product.
Claims (1)
1, a kind of metal, rubber and plastic composite pipe fitting big envelope, by pipeline (1), nut (2), metallic envelope (3), rubber ring (4), pipe fitting (5) is formed, it is characterized in that: metallic envelope (3) is enclosed within on the pipeline (1), and rubber ring (4) places the back of metallic envelope (3), and pipe fitting (5) is enclosed within on the metallic envelope (3) from behind, nut (2) is enclosed within on the metallic envelope (3) from the front, and is threaded with pipe fitting (5).
