By adopting technique scheme, the arrangement mode of the first installing hole and the second installing hole is neat, and the first installing hole and the second installing hole be conducting setting, facilitates the machine-shaping of the first installing hole and the second installing hole, reduces production difficulty, increases work efficiency.
The utility model is further set to, and quincunx through hole is inwardly given prominence to and is formed with four bare terminal ends, four bare terminal end corresponding four groups of installing hole groups settings respectively.
By adopting technique scheme, quincunx through hole is inwardly given prominence to and is formed with four bare terminal ends, four bare terminal ends can be by the clamping of valve rod firm stable, four bare terminal end corresponding four groups of installing hole groups settings respectively, make through hole and four groups of installing hole marshallings on upper mounting plate tight, and the structural strength forming is higher.
The utility model is further set to, and lower installation board is rounded, and circular hole is positioned at the center of lower installation board, on lower installation board, has some the 3rd installing holes along circular hole circle distribution.
By adopting technique scheme, lower installation board is rounded, and upper mounting plate is square, and can meet the valve of difformity or different structure and the installation needs of ring flange, and versatility is stronger.
The utility model is further set to, and is formed with smooth clamping face on described bare terminal end.
By adopting technique scheme, on bare terminal end, be formed with smooth clamping face, when bare terminal end grips valve rod, can not only play the fixing effect of supporting to valve rod, the frictional resistance of smooth clamping face is less simultaneously.
Compared with prior art, the utility model has the advantage of: this ring flange bracket general is strong, can on different valves, use, meet the installation requirements of the large small flange plate of different size, and can not only play and support fixing effect valve rod, clamp resistance less simultaneously.
