Limitation.
Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of improved flange face bolt, including first
Flange 1, the right end of first flange 1 are equipped with second flange 2, bolt 3 are equipped between first flange 1 and second flange 2；
First flange 1 is provided with the first circular trough 11, and the first sealing shroud 14 is socketed in the first circular trough 11, has sealing
Effect, first flange 1 are provided with square groove 12, square block 34 are connected in square groove 12, pass through square groove 12 and square block 34
Cooperation, can make square block 34 that can not rotate, first flange 1 is provided with first through hole 13, sliding in first through hole 13
Dynamic to be socketed with bolt 3, first through hole 13 is that bolt 3 provides installation space；
Second flange 2 is contacted with first flange 1, and second flange 2 is provided with the second circular trough 21,21 inner sleeve of the second circular trough
It is connected to the second sealing shroud 23, the second sealing shroud 23 is close to the first sealing shroud 14, has sealing function, and second flange 2 is provided with
Second through-hole 22, sliding sleeve is connected to bolt 3 in the second through-hole 22, and the second through-hole 22 is that bolt 3 provides installation space, the second method
The right end of orchid 2 is fixedly connected with guide holder 24, and guide holder 24 is provided with pilot hole 25, and sliding sleeve is connected to positioning pin in pilot hole 25
26, pilot hole 25 has guiding role to positioning pin 26, and the outside of positioning pin 26 is socketed with spring 27, and the outside of positioning pin 26 is solid
Surely it is socketed with support ring 28, spring 27 is compressive state, has compression elasticity effect to support ring 28；
The right end of bolt 3 is fixedly connected with terminal pad 31, and terminal pad 31 is provided with locating slot 32, is connected in locating slot 32
Positioning pin 26 can make terminal pad 31 that can not rotate by the cooperation of positioning pin 26 and locating slot 32, so that spiral shell
