Equipped with protrude from the first rubber tube lateral wall and it is embeddable in first limiting slot first limit raised line.
In sealed connection flange of the present invention, which is four the first limiting slots, should
For four the first limiting slot spaced sets in the first connection medial wall of the tube, which is four first
Connecting hole, four first limiting slots distinguish face four first connecting holes.
In sealed connection flange of the present invention, the first limit raised line face second connecting hole.
In sealed connection flange of the present invention, which is equipped with to the rubber disc first
The sealing ring that face is protruded and can be wrapped on the ring flange lateral wall, the sealing ring internal diameter are equal to the flange external diameter.
In sealed connection flange of the present invention, which is equipped with to the ring flange lateral wall indent
Sunken ring-shaped depression slot, the sealing ring inner sidewall are equipped with the embeddable annular protruding rib in the ring-shaped depression slot.
Implement sealed connection flange of the invention, when having the advantages that using sealed connection flange of the invention,
Before carrying out flanged joint, the first rubber tube outer wall surface can be smeared a certain amount of glue, be inserted into the first connection
Bonding is fixed in cylinder, so that rubber disc abutting ring flange, is then attached, by two methods again with other ring flanges
When blue disk is attached, the connection that the first connecting hole, the second connecting hole are then passed through another ring flange later is passed through using bolt
Hole, be spirally connected with nut locking later, and rubber pad disk folder is set among two ring flanges at this time, plays good sealing effect.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing:
Fig. 1 is the decomposition texture schematic diagram that the present invention is tightly connected flange.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
As shown in Figure 1, in sealed connection flange first embodiment of the invention, the connecting flange 1 include ring flange 13,
It is set to the first through hole 2 at 13 middle part of ring flange, is fixedly arranged on what 13 first Middle face of ring flange was connected to the first through hole 2
The second through-hole that first connecting cylinder 3, pad are set to the rubber disc 4 in 13 second face of ring flange, are set to 4 middle part of rubber disc
5, it is fixedly arranged on the first rubber tube that 4 first face of rubber disc is connected to and is inserted into the first through hole 2 with second through-hole 5
6, the aperture of the first through hole 2 is equal to the internal diameter of first connecting cylinder 3, and the aperture of second through-hole 5 is equal to the first rubber tube 6
Internal diameter, the outer diameter of first rubber tube 6 are equal to the internal diameter of first connecting cylinder 3, which is equipped at least three first
Connecting hole 7 is equipped with the second connecting hole 8 with 7 corresponding position of the first connecting hole on the rubber disc 4.
It, can be by 6 outer wall table of the first rubber tube before carrying out flanged joint when using sealed connection flange 1 of the invention
A certain amount of glue is smeared in face, is inserted into bonding is fixed in the first connecting cylinder 3, so that the abutting flange of rubber disc 4
Then disk 13 is attached with other ring flanges 13 again, when being attached two ring flanges 13, pass through first using bolt
The connecting hole of another ring flange 13 is then passed through after connecting hole 7, the second connecting hole 8, be spirally connected with nut locking later, at this time rubber
Rubber mat disk 4 is located among two ring flanges 13, plays good sealing effect.
