Description
Technical field
The utility model is related to technical field of pipeline connection, more particularly to a kind of fast connecting device of pipelines.
Background technology
The conveying of the fluid media (medium)s such as Oil, Water, Gas generally uses pipeline mode.At present, the connection between pipeline is main
Using welding or flange connection method, the pipeline frequently changed is needed to connect especially for those, such as pneumatic steelmaking oxygen rifle enters,
The connection of outlet conduit and oxygen channel, flange connection is the most frequently used connection method.Flange connection advantage be it is simple in construction,
Have the disadvantage to need to dismantle some groups of bolt and nuts when changing every time, be typically at least 6 groups, 8 groups, it is higher for those seal requests
, the group number of connecting bolt is then more, and time-consuming long, inefficiency, labor strength is big.In addition, between flange generally
Sealed by rubber blanket or asbestos packing, sealing effectiveness is poor, be easily caused Joint failure, occur oil leak, leak, deflation phenomenon.
Utility model content
To overcome prior art defect, the technical problem that the utility model is solved is to provide a kind of pipeline and quickly connects dress
Put, it is simple in construction, it is easy to use, sealed by the conical surface between upper lower body and O-shaped rubber ring, it is only necessary to unclamp or tighten 2 groups of bolts
Pipeline connection can be rapidly completed, connection is reliable, time-consuming short, high working efficiency, labor strength is low.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of fast connecting device of pipelines, including upper body, bolt, nut, O-shaped rubber ring, lower body, bearing pin, pin, its feature
It is that the bolt is articulated and connected by bearing pin, pin and lower body；Socket connection between the upper body, lower body, passes through O-shaped rubber
Circle sealing, is fastened together using bolt, nut.
Circular conical surface provided with matching between the upper body, lower body, its taper preferably 1:10.
Horizontally U-shaped notch is provided with the upper body flange, circular conical surface is provided with the O-shaped rubber with O-shaped rubber ring matched design
Cushion rubber notch.
Distance between 2 gussets for being provided with through hole, two gussets is provided with along pipe level axisymmetrical compare spiral shell on the lower body
The big 1-3mm of external diameter of bolt.
Compared with prior art, the beneficial effects of the utility model are：
1) it is simple in construction, it is easy to use, it is only necessary to which that pipeline connection can be rapidly completed by unclamping or tightening 2 groups of bolts, solve pipe
Road connection, which is changed, takes long problem；
2) sealed between upper body, lower body by the conical surface and O-shaped rubber ring, good sealing effect, be not susceptible to oil leak, leak,
Deflation phenomenon, solves loss of connectivity issue；
3) labor strength is small, high working efficiency.

Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
See Fig. 1-Fig. 6, the utility model is related to a kind of fast connecting device of pipelines, including upper body 1, bolt 2, nut 3, O
Type rubber ring 4, lower body 5, bearing pin 6, pin 7, the bolt 2 are articulated and connected by bearing pin 6, pin 7 and lower body 5, and bolt 2 can be around bearing pin
6 rotate up and down；Socket connection between the upper body 1, lower body 5, is sealed by O-shaped rubber ring 4, is fastened using bolt 2, nut 3
Link together.O-shaped rubber ring 4 needs settable 3-4 roads according to connection.
Circular conical surface provided with matching between the upper body 1, lower body 5, its taper preferably 1:10.
Horizontally U-shaped notch 11 is provided with the flange of upper body 1, U-shaped opening distance is easy to than the big 1-3mm of external diameter of bolt 2
The free movement of bolt 2, circular conical surface is provided with O-shaped rubber ring notch 12, with the matched design of O-shaped rubber ring 4.
On the lower body 5 distance between 2 gussets 21 for being provided with through hole, two gussets 21 is provided with along pipe level axisymmetrical
Than the big 1-3mm of external diameter of bolt 2, it is easy to the free movement of bolt 2.
A kind of method that pipeline is quickly connected, comprises the following steps：
1) upper body 1 is connected with intending one end of connecting pipe, lower body 5 is connected with intending the other end of connecting pipe；
2) bolt 2 is articulated and connected by bearing pin 6, pin 7 and lower body 5, nut 3 is screwed on bolt 2, and makes the nut 3 of bolt 2
