Detailed Description

The technical solution of the present invention is further explained with reference to the accompanying drawings and specific embodiments.

Example one

As shown in fig. 1-3, the butterfly valve installation auxiliary device provided by the utility model comprises a pipeline 1, a valve body 2 and a valve rod 4 connected to the valve body 2, wherein the pipeline 1 and the valve body 2 are fixedly connected through a flange 3, the flange 3 comprises a first flange 31 and a second flange 32, the first flange 31 and the second flange 32 are equal in size and same in shape, the first flange 31 is fixedly connected with the pipeline 1, the second flange 32 is fixedly connected with the valve body 2, the outer surface of the valve rod 4 is detachably connected with a pair of installation pieces 5, the outer annular surfaces of the two installation pieces 5 are fixedly connected with a connecting arm 6, the deviating ends of the two connecting arms 6 are fixedly connected with an arc-shaped lap cover 7, the bottom of the arc-shaped lap cover 7 is provided with a lap groove 11, the width of the lap groove 11 is slightly larger than the sum of the thicknesses of the first flange 31 and the second flange 32, therefore, the arc-shaped lap cover 7 can simultaneously cover the first flange 31 and the second flange 32 through the lap groove 11. The radian of the top wall of the lapping groove 11 is the same as that of the ring surface of the flange 3, so that the arc lapping cover 7 is more stable on the flange 3.

In this embodiment, when installing the butterfly valve, align the valve body 2 and the pipeline 1 as shown in the figure and place, make the arc take cover 7 wrap the first flange 31 and the second flange 32 by upper portion simultaneously, because the arc takes cover 7 to be through linking arm 6 and installation piece 5 and valve rod 4 stable connection, the butterfly valve accessible arc takes cover 7 to take on ring flange 3, consequently can make whole butterfly valve keep the position that the figure aligns with pipeline 1, need not to hand or hold in the palm, has made things convenient for subsequent operations such as inserting the bolt.
