Detailed Description

The utility model will now be further described by way of specific examples with reference to the accompanying drawings, which are given by way of illustration only and not by way of limitation.

The utility model provides a flange, includes first flange 1, first flange 1 and 2 butt joints of second flange, inside groove 5 has all been seted up on first flange 1 and the second flange 2, install inner seal 4 on the inside groove 5, first flange 1 carries out the buckle by fastener 10 again after 2 butt joints of second flange, there is observer 13 in the fastener 10, prevents through the fastener that the clearance that appears between the messenger flange is constantly enlarged because of the bolt looseness, finally leads to droing, adds the setting of observer, is convenient for in time discover that the weeping condition appears in flange joint.

The center positions of the first flange 1 and the second flange 2 are respectively provided with a through hole 3, the sections of the inner grooves 5 on the first flange 1 and the second flange 2 are trapezoid, the sections of the inner sealing rings 4 are hexagonal, and the inner sealing rings 4 are matched with the inner grooves 5 in the first flange 1 and the second flange 2, and the contact surfaces of the inner sealing rings 4 and the inner grooves 5 are denser due to the fact that the first flange 1 and the second flange are extruded to the center during installation, so that sealing can be better carried out. The positioning blocks 6 are annularly arranged on the first flange 1, the positioning grooves 7 are annularly arranged on the second flange 2, the positioning blocks 6 are matched with the positioning grooves 7, and the two flanges are prevented from being deviated and cannot be abutted to the mounting holes when the two flanges are mounted subsequently through successful abutting joint of the positioning blocks 6 and the positioning grooves 7; six flange mounting holes 8 are formed in the annular lines on the outer sides of the first flange 1 and the second flange 2. The fastener 10 is provided with two fastener mounting holes 11, the fastener mounting holes 11 correspond to two adjacent flange mounting holes 8 on the flange, and the flange mounting holes 8 are connected with the fastener mounting holes 11 through bolts 12. The top view of the fastener 10 is a third ring, and the cross section of the fastener 10 is ; the observer 13 is a transparent liquid storage device, and the observer 13 is positioned at the center of the fastener 10; the front of the fastener 10 is one third of a circle, the three fasteners 10 need to be connected in a surrounding mode for reinforcement during flange connection, and the observer 13 only needs to be installed on the fastener 10 positioned at the lowest position.

The working flow of the utility model is as follows: when an installer installs the flange, the pipeline connecting end of the first flange 1 is connected with the pipeline, then the inner sealing ring 4 is placed in the corresponding inner groove 5 on the first flange 1, the positioning block 6 of the first flange 1 is in butt joint with the positioning groove 7 of the second flange 2, the edge of the first flange 1 which is in butt joint with the second flange 2 is placed in the groove of the fastener 10, the bolts 12 penetrate through the fastener mounting holes 11 and the flange mounting holes 8, the bolts 12 are screwed, when the bolts 12 are loosened, the flanges are buckled by the fastener 10, so that larger cracks are prevented from being formed in connection between the flanges due to loosening of the bolts 12, liquid in the flanges permeates out through the inner sealing ring 4 and is influenced by gravity, and effluent liquid can flow into the fastener 10 with the observer 13 positioned below, so that inspection personnel can find abnormal loosening and leakage;
