Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1-6, a retainer flange structure convenient for replacing a vacuum sealing ring comprises a vacuum chamber flange 1, a retainer flange 2, a door flange 3, a clamping block 5, a hanging component 7 and a sealing ring 12;
the upper end of the vacuum chamber flange 1 is provided with a mounting positioning groove 4 for mounting a hanging component 7;
the upper part of the retainer flange 2 is provided with more than one mounting hole 6 for mounting pendant assemblies 7, the pendant assemblies 7 corresponding to the number of the mounting holes 6 are fixed in the mounting holes 6, and the pendant assemblies 7 comprise pins 10, gaskets 8 and screws 9;
a clamping block 5 is arranged in the middle of the top of the retainer flange 2;
sealing grooves 11 are formed in two sides of the retainer flange 2, and sealing rings 12 are arranged in the sealing grooves 11.
The sealing groove 11 on the retainer flange 2 is a dovetail groove.
The retainer flange 2 is provided with 2 mounting holes 6, and each mounting hole 6 is internally provided with a hanging component 7.
The pin 10 of the pendant assembly 7 is inserted into the mounting hole 6, and a gasket 8 and a screw 9 are sequentially arranged on the other side of the retainer flange 2 to prevent the pin 7 from being separated from the mounting hole 6.
The clamping block 5 is of an inverted boss structure, and is convenient to clamp remotely through a manipulator.
The surface of the clamping block 5 is knurled, so that the clamping friction force is increased.
The positions and the number of the installation positioning grooves 4 correspond to those of the hanging components 7.
A clamping block 5 is arranged in the middle of the top of the retainer flange 2.
The installation positioning groove 4 is a double U-shaped groove, and the upper groove is large and the lower groove is small, so that the hanging component 7 can be conveniently installed in place.
When the invention works, the sealing rings 12 are arranged in the sealing grooves 11 on two sides of the retainer flange 2. The manipulator lifts the retainer flange 2 by clamping the clamping blocks 5, and the hanging component 7 is installed in the installation positioning groove 4, so that the retainer flange 2 is installed on the vacuum chamber flange 1, and the door flange 3 compresses the retainer flange 2 from the other side, thereby realizing double-side sealing.
