One end that the connecting rod 31 is connected, when being connected in order to top 32a on the blind flange 20, the accumbency of depression bar 32 exists
On blind flange 20, it is to avoid space-consuming.
In the present embodiment, the shape of the depression bar 32 can be the shape of rule, such as cylindricality, plate shape or not advise
In shape then, this preferred embodiment, the cylinder of the depression bar 32, the diameter of the cylindrical depression bar 32 by the depression bar 32 with it is described
One end to the other end of the depression bar 32 that connecting rod 31 is connected successively decreases, and it is larger that the top 32a is located at the volume of depression bar 32
One end, so can preferably ensure that top 32a is connected on the blind flange 20.
To sum up, the integral installation process below in conjunction with 1 to 5 pair of flange assembly of the present invention of accompanying drawing carries out overall elaboration：
Gone forward blind flange 20 is installed on into flange seat 10, connecting rod 31 and depression bar 32 can be installed on blind flange 20 in advance
On, its specific installation process is：Installation portion 312 is inserted into mounting groove 322 first, rotating shaft 33 is then passed through into the first axis hole
301 and second after axis hole 302, are processed to the two ends of the rotating shaft 33, so that rotating shaft 33 is pacified to installation portion 312 and two
Dress journal stirrup 321 carries out spacing；Install after connecting rod 31 and depression bar 32, it is possible to convenient that blind flange 20 is installed on flange seat 10
On；Now, then by the limiting section 311 of connecting rod 31 passed through from first through hole 101, to stretch in cavity, then stir connecting rod 31
The connecting rod 31 is moved in the second through hole 102, coordinated by the second through hole 102 and limiting section 311, limit connecting rod 31 and method
The position of blue seat 10, then blind flange 20 is socketed on flange seat 10, depression bar 32 is then rotated, the depression bar 32 is promoted blind flange
20 move to the direction of flange seat 10, until when the top 32a of the depression bar 32 is connected on the blind flange 20, stopping turning
Dynamic, now the depression bar 32 fastens the blind flange 20 on the flange seat 10, it is ensured that blind flange 20 is firmly fixed
On flange seat 10, and whole assembling process is without twisting screw bolt and nut so that operates very convenient, improves assembling effect
Rate, reduces assembly cost.
