Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1-3, a liquid pipeline flange assembly comprises a double-end flange 1, a cover groove 2 and a circulation groove 3, and further comprises a one-way plugging valve cover 4 for plugging the circulation groove 3, wherein the cover groove 2 is respectively arranged at two ends in the double-end flange 1, the circulation groove 3 is arranged between the cover grooves 2 in a penetrating manner, one-way plugging valve covers 4 for covering the circulation groove 3 are respectively arranged at one ends in the cover groove 2, the top of the one-way plugging valve covers 4 is rotationally connected with the top in the cover groove 2 through a rotating shaft, a rectangular insertion channel 6 is arranged at one end bottom in the cover groove 2, a rectangular push rod 9 is inserted in the rectangular insertion channel 6, a wedge plate 10 is welded and connected with the top of the rectangular push rod 9, one side of the wedge plate 10 is rotationally connected with a roller 11 through the rotating shaft, and a slope block 5 corresponding to the roller 11 is arranged at the bottom of the one-way plugging valve covers 4.

The bottom of the rectangular insertion channel 6 is provided with a threaded hole 7 through the double-end flange 1, a screw rod 8 is inserted into the threaded hole 7 in a threaded manner, the top of the screw rod 8 is rotationally connected with the bottom of the rectangular push rod 9 through a bearing, and the bottom end of the screw rod 8 penetrates out of the threaded hole 7 to be welded and connected with a hand wheel 12; as shown in fig. 1-3, the hand wheel 12 is convenient for a person to rotate the screw rod 8, so that the screw rod 8 pushes and pulls the rectangular push rod 9 based on the thread movement, and the roller 11 can roll and push the one-way valve cover 4.
