Connecting hole links together two metal bellows, but there are the following problems using such mode:One, needing will many metal
Bellows is connected to achieve the purpose that lengthening, but due to the complex manufacturing technology of flange, the connection for being easily deformed displacement, and using
Bolt is also more, and when construction is not easy to install, and construction cost is higher, has an effect on use;Two, since angle steel flange is and wavy metal
What pipe welded together, it inevitably causes end face of flange uneven in the welding process, will produce after the connection of two metal bellows
Compared with big gap, lead to poor sealing;Three, the metal bellows with flange can cause serious integrally after high temperature galvanizing
Deformation, to further result in poor sealing;Four, behind metal bellows embedment underground, when two adjacent sections metal bellows is born
Pressure it is uneven or due to support metal bellows ground occur differential settlement when, adjacent two metal bellows will be sent out
The raw changing of the relative positions can cause the bolt of connection metal bellows end flanges to be cut, to make two metal bellows nozzles of connection
It is staggered, not only influences normal use, the pedestrian of traveling thereon or vehicle can also be damaged;Five, due to metal bellows
It is an entirety, the freight volume of per car is few, and transport is inconvenient and cost is higher.
Invention content
In order to solve the problems in the existing technology, the utility model provides a kind of Spliced type bellows.
The technical solution that the utility model solves the above problems is:A kind of Spliced type bellows, including the first bellows
And second bellows, first bellows include the first connector, the second connector and the first expansion joint, first expansion
One end of section is connected with the first connector, and the other end is connected with the second connector, and second bellows includes third connector, the 4th connects
Head and the second expansion joint, one end of second expansion joint are connected with third connector, and the other end is connected with the 4th connector, described
Attaching nut is also associated on third connector, the attaching nut mutually welds with third connector;
The outer end of the third connector is equipped with the first Tapered Cup and first boss, the outer diameter of first Tapered Cup by outer and
The rear end of interior gradual increase, first Tapered Cup is connected with first boss;
Second connector outer end is equipped with external screw thread, and second connector outer end is internally provided with inner conical surface, the inner conical surface
Diameter ecto-entad between reduce;
Internal thread is equipped in the attaching nut, the internal thread is matched with the external screw thread of the second connector;
Second connector is connected with third connector by attaching nut, right end and the third connector phase of the attaching nut
Even, left end is connected with the second connector, and first Tapered Cup is socketed in the second connector;
First Tapered Cup is equipped with sealing ring mounting groove;
The male cone (strobilus masculinus) of first Tapered Cup is matched with the inner conical surface of the second connector, is set between the inner conical surface and male cone (strobilus masculinus)
There are sealing ring, the sealing ring to be arranged in sealing ring mounting groove.
The utility model has advantageous effect:
Even if the utility model convenience in transport can also manually transport, both ensure in the construction site of not transporting equipment
Construction speed, and substantially saved transportation cost;By attaching nut make the second connector and third joint it is smoother,
More firm stable, junction can bear the external impact force of bigger without tube coupling deformation occurs;The inner conical surface and male cone (strobilus masculinus)
Between be equipped with sealing ring, further enhance the sealing effect of connection structure;The utility model has the advantages of convenient installation, and construction greatly improved
Efficiency has saved construction cost.
