Abstract
The utility model relates to an inner connecting piece of a pipe. The utility model relates to a connecting piece, particularly a connecting piece of a pipe. At present a pipe is connected with a pipe through a screw thread, because the pipe is long, the connecting mode that the whole pipe is rotated is bothersome, the connection is easily damaged, in addition, the connection through the screw thread is not tight, liquid or gas in the pipe easily leaks outwards, and an accident happens. The inner connecting piece of a pipe comprises a connecting body (1) which is in a hollow structure, wherein, the outer part of which is square and the inner part of which is circular. The square body is provided with a screw thread hole (2). The inner circle is provided with an inner screw thread (3). The square body is provided with a groove (4) in which a sealing ring (5) is embedded. The other surface which is opposite to the sealing ring (5) on the square body is provided with a groove (6). The screw thread hole (2) penetrates through the connector (1) and is positioned in the area of the groove (6). The utility model solves the problems that the connection through a screw thread between pipes is easily damaged, and gas and liquid in the pipes can easily leak outwards. The utility model can be widely used for the connection between pipes.
Description
Technical field: the utility model relates to a kind of link, particularly the link between pipe fitting.
Background technique: pipe mostly is with being connected of pipe way and is threaded at present, promptly on two interconnective pipes of need, process internal and external threads, connect then, but because pipe is generally all very long, connect very trouble by the method for rotating whole pipe, and damage easily, in addition, being threaded does not closely make liquid in pipe or gas leak easily, causes unnecessary accident.
Summary of the invention: the utility model relates to a kind of pipe way interconnecting piece, can be so that the convenient connection of pipe way can reach good sealing effect again.The purpose of this utility model is achieved in that its composition of pipe way interconnecting piece comprises connecting body 1, and described connecting body 1 is the square-outside and round-inside hollow structure, has tapped hole 2 on described side's body, on the circle internal thread 3 is arranged in described.Fluted 4 on described side's body, in described groove 4, stud with seal ring 5, the another side opposite with seal ring 5 is fluted 6 on described side's body, and described tapped hole 2 is through connecting body 1 and in the zone of groove 6.Advantage of the present utility model is: connecting body 1 is the square-outside and round-inside hollow structure, on side's body tapped hole 2 is arranged, can make things convenient for and being connected of pipe fitting upper flange, on the interior circle internal thread 3 is arranged, internal thread 3 can be fixed on certain with the pipe that link connects with bolt, in addition, also can be connected by screw thread with threaded pipe, make things convenient for the connection of distinct interface pipe, the side is fluted 4 on the body, studs with seal ring 5 in the groove 4, for link and being connected of pipe playing seal action, another side at square body is provided with groove 6, tapped hole 2 is located in the zone of groove 6, when flange connects, can put pad in groove 6, not only can play seal action, and can clamping bolt make connect between flange tightr.
Description of drawings: Fig. 1 is a main sectional view of the present utility model, and Fig. 2 is a rear view of the present utility model, and Fig. 3 is the plan view of Fig. 1.
Embodiment: the pipe way interconnecting piece, its composition comprises connecting body 1, described connecting body 1 is the square-outside and round-inside hollow structure, respectively has a tapped hole 2 on four angles on described side's body, on the circle internal thread 3 is arranged in described.To have the two tubes connection of flange by the tapped hole on the square body 2 after, available bolt is fixed on certain by the internal thread on the interior circle with pipe, also the pipe that has flange can be connected with screwed pipe.On described side's body fluted 4, in described groove 4, stud with seal ring 5, be provided with four grooves 6 on four angles of another side opposite with seal ring 5 on described side's body, described four tapped holes 2 are all through connecting body 1 and in four zones of groove 6.In groove 6, put pad, the one, can play seal action, the 2nd, can make the connection of flange tightr by fixing bolt.
Claims (3)
1, a kind of pipe way interconnecting piece, its composition comprises connecting body (1), it is characterized in that described connecting body (1) is the square-outside and round-inside hollow structure, has tapped hole (2) on described side's body, on the circle internal thread (3) is arranged in described.
2, according to the described pipe way interconnecting piece of claim (1), it is characterized in that on described side's body fluted (4), in described groove (4), stud with seal ring (5).
3, pipe way interconnecting piece according to claim 1 and 2 is characterized in that another side fluted (6) opposite with seal ring (5) on described side's body, and described tapped hole (2) is through connecting body (1) and in the zone of groove (6).
