Abstract
The utility model discloses a circumferential sealing device for a water drainage pipe to solve the problems that an existing sealing device for a water drainage pipe is relatively complex in structure, difficult to machine, high in production cost and the like. According to the circumferential sealing device for the water drainage pipe, a ring-shaped movable limiting flange (4) is sleeved on a second water drainage pipe (6), the movable limiting flange (4) is connected with a seal ring seat (2) on a first water drainage pipe (1) through a plurality of bolts, therefore, a waistcoat (5) on the second water drainage pipe (6) is arranged in and movably connected with a cavity which is formed by the seal ring seat (2) and the movable limiting flange (4), an aerating seal ring (3) is arranged on the outer circle surface of the waistcoat (5), and the aerating seal ring (3) makes contact with the inner circle surface of the seal ring seat (2) at one end of the first water drainage pipe (1) and plays a sealing role. Therefore, the circumferential sealing device has the advantages of being simple in structure, easy to machine and low in production cost.
Description
Technical field
The utility model relates to a kind of waste pipe seal arrangement, relates in particular to a kind of by the spacing flange of activity, seal ring, first waste pipe and second circumferential seals that is used for waste pipe that waste pipe is formed.
Background technique
At present, a kind of so rotatable collapsible honeycomb duct is disclosed on the market, its structural feature is: be made up of honeycomb duct, unwinding device, bend pipe and the steering gear, one end of honeycomb duct is connected with unwinding device one end, the other end of unwinding device is connected with an end of another root honeycomb duct, the other end of another root honeycomb duct is connected with unwinding device one end by the steering gear, bend pipe, and the unwinding device the other end is connected with last root honeycomb duct; Unwinding device is made up of packing holder, gas-flow closure circle, worm gear and worm screw, be provided with the gas-flow closure circle at packing holder, towards an end of another root honeycomb duct the worm screw that is connected with power is installed at packing holder, is fixed on another root honeycomb duct one end with the worm gear of worm meshing; The gas-flow closure circle is made up of seal ring, packing holder, first waste pipe and second waste pipe, be provided with packing holder at first waste pipe one end, be provided with sleeveless jacket at second waste pipe one end, packing holder is provided with the dovetail groove that can place seal ring, and the cross section of seal ring also is arranged to dovetail shaped.Therefore, this structure is complicated, processing is difficult, cost of production is higher.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy processing, the circumferential seals that is used for waste pipe that cost of production is lower.
For achieving the above object, the utility model is used for the circumferential seals of waste pipe, by the gas-flow closure circle, packing holder, first waste pipe and second waste pipe are formed, be provided with packing holder at first waste pipe one end, be provided with sleeveless jacket at second waste pipe one end, be set with in the form of a ring movable spacing flange at second waste pipe, movable spacing flange is connected with packing holder on first waste pipe by a plurality of bolts, make second sleeveless jacket on the waste pipe place in the cavity that packing holder and movable spacing flange constitute and be movably connected, at the sleeveless jacket outer round surface gas-flow closure circle is installed, the gas-flow closure circle contacts with the packing holder internal circular surfaces that is arranged on first waste pipe one end again, seals.
Described packing holder is arranged to axial cross section is the L shape.
Described sleeveless jacket outer round surface is provided with the annular groove that can lay the gas-flow closure circle, and this groove axial cross section is square-shaped, annular groove bottom be provided with can be by second waste pipe in the hole of locating that the boundary communicates and placing pipeline.
After adopting this structure, owing to the movable spacing flange that is set with at second waste pipe in the form of a ring, movable spacing flange is connected with packing holder on first waste pipe by a plurality of bolts, make second sleeveless jacket on the waste pipe place in the cavity that packing holder and movable spacing flange constitute and be movably connected, at the sleeveless jacket outer round surface gas-flow closure circle is installed, the gas-flow closure circle contacts with the packing holder internal circular surfaces that is arranged on first waste pipe one end again, seals.Again because described sleeveless jacket outer round surface is provided with the annular groove that can lay seal ring, and this groove axial cross section is square-shaped, annular groove bottom be provided with can be by second waste pipe in the hole of locating that the boundary communicates and placing pipeline.Thereby reach simple in structure, easy processing, purpose that cost of production is lower.
