Abstract
An internal-external thread movable joint is characterized by comprising an external thread bell end, a nut and an internal-external thread bell end. Firstly the external thread bell end is arranged in the nut, and then external threads of the internal-external thread bell end are screwed into the nut, so that the external thread bell end and the internal-external thread bell end are pressed against each other in a plane-to-plane mode. An O-shaped sealing ring is installed at the position where the internal-external thread bell end and the external thread bell end are pressed against each other. The installation is not affected by the quality of workers, and glue is not needed for bonding, and therefore fast installation is achieved. Besides, the range of application of the movable joint is wide. According to the internal-external thread movable joint, fast connection of pipe fittings is achieved, construction period is shortened, replacement is convenient, construction quality is improved, energy consumption is reduced, environmental protection is facilitated, equipment investment is decreased, production cost is reduced, and economic benefit and social benefit are obvious.
Description
Technical field
The utility model relates to Union.
Background technique
Common internal thread union refers to tapped pipe joint, is modal a kind of pipe fitting in industry and the life plumbing, and threaded for union makes the connection of pipeline become simpler, and dismounting and change is also easier, has greatly saved the cost that pipeline connects.But its defective is two can only connect internal thread tube piece, has narrow limitation for the requirement of pipe fitting.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, provides a kind of effective change pipeline to connect, and makes pipeline connect variation, does not need other braking force, simple in structure, low cost of manufacture, removes and installs easily Union.
The technological scheme of the utility model Union is, it is characterized in that comprising outside thread bellmouth, nut and internal and external threads bellmouth, the outside thread bellmouth is arranged in the nut, screwing in the nut of internal and external threads bellmouth, outside thread bellmouth and internal and external threads socket plan are to pressing, and internal and external threads bellmouth and outside thread bellmouth are to pressure place mounting O-shaped seal ring.
The utility model discloses a kind of Union, at first the outside thread bellmouth is arranged in the nut, screwing in the nut the internal and external threads bellmouth again, outside thread bellmouth and internal and external threads socket plan are to pressing, internal and external threads bellmouth and outside thread bellmouth during installation, are not affected by quality of workers pressure place mounting O-shaped seal ring, need not the glue bonding, thereby realize quick mounting.In addition, this union Applicable scope is extensive, has realized the quick connection of pipe fitting, shortens construction period; it is convenient to change, and improves construction quality, reduces energy consumption, is beneficial to environmental protection; reduce equipment investment, cost of production is lower, has obvious economic benefit and social benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model Union.
Embodiment
The utility model relates to a kind of Union, as shown in Figure 1, it is characterized in that comprising outside thread bellmouth 1, nut 3 and internal and external threads bellmouth 4, outside thread bellmouth 1 is arranged in the nut 3, screwing in the nut 3 of internal and external threads bellmouth 4, outside thread bellmouth 1 and internal and external threads bellmouth 4 planes are to pressing internal and external threads bellmouth 4 and 1 pair of pressure place of outside thread bellmouth mounting O-shaped seal ring 2.At first outside thread bellmouth 1 is arranged in the nut 3, screwing in the nut 3 internal and external threads bellmouth 4 again, outside thread bellmouth 1 and internal and external threads bellmouth 4 planes are to pressing, internal and external threads bellmouth 4 and 1 pair of pressure place of outside thread bellmouth mounting O-shaped seal ring 2, during installation, not affected by quality of workers, need not the glue bonding, thereby realize quick mounting.In addition, this union Applicable scope is extensive, has realized the quick connection of pipe fitting, shortens construction period; it is convenient to change, and improves construction quality, reduces energy consumption, is beneficial to environmental protection; reduce equipment investment, cost of production is lower, has obvious economic benefit and social benefit.
