Detailed Description

Referring to fig. 1-2, the rotary plate breaking valve of the invention is connected in series with a loading arm and a loading arm of a tank car and comprises a female valve body, yang Fati, a first groove clamp 5, a second groove clamp 6, a locking cap 7 and a locking bolt 8, wherein the female valve body and a male valve body are symmetrically identical in structure, the female valve body consists of a pipe body 1, an X-shaped bracket 2, a valve plate 3, a fixed base 4 and a fixed base 4, the fixed base 4 is fixed on the pipe wall of the pipe body 1, and the valve plate 3 is arranged in the pipe body 1 through the X-shaped bracket 2; the X-shaped support 2 is composed of a fixed plate 21 and a triangular limiting plate 22, the fixed plate 21 and the triangular limiting plate 22 are crossed between the valve plate 3 and the fixed base 4, one end of the fixed plate 21 is rotationally connected with the valve plate 3, the other end of the fixed plate 21 is rotationally connected with the fixed base 4, one end of the triangular limiting plate 22 is rotationally connected with the valve plate 3, the other end of the triangular limiting plate 22 is rotationally connected with the fixed base 4, one support arm of the triangular limiting plate 22 can prop against the inner wall of the pipe body 1 to play a limiting role, the valve plate 3 and the cross section of the pipe body 1 can be kept vertical, and the fluency of the flow of liquid medium is guaranteed.

When the invention is normally used for conveying liquid, the edge of the bottom surface of the valve plate 3 of the female valve body is contacted with the edge of the bottom surface of the valve plate of the male valve body, and the valve plate 3 cannot rotate no matter how the liquid medium flows under the limiting action of the triangular limiting plate 22.

The first groove card 5 one end is equipped with oval hole, second groove card 6 one end is equipped with the U-shaped recess, the oval hole of first groove card 5 is crossed to locking bolt 8's screw rod cluster, the U-shaped recess of second groove card 6 one end is arranged in to locking bolt 8's screw rod, first groove card 5 one end is connected through locking bolt 8 with second groove card 6 one end, leave the clearance between first groove card 5 one end and the second groove card 6 one end, first groove card 5 other end and second groove card 6 other end all are equipped with the latch segment, wherein female valve body and Yang Fati pass through first groove card 5 and second groove card 6 fixed connection, locking cap 7 cover is on the latch segment.

Referring to fig. 3, a wire rope is tied to the rope hole 71 of the locking cap 7, and the other end of the wire rope is fixed to the upright post, so that when the liquid medium is loaded into the tank wagon by using the crane pipe, one end flange of the pipeline of the crane pipe is connected with the tank wagon, and the other end of the pipeline of the crane pipe is connected with the conveying pipeline, and the liquid medium is loaded and unloaded by the crane pipe. When a fire breaks out on site, a driver starts the tank truck immediately when the crane pipe and the flange of the tank truck are not yet opened, a steel wire rope with one end fixed on the upright post and the other end fixed on the locking cap 7 is tensioned first, the rear locking cap 7 is pulled off from one locking block of the first slot clamp 5 and the second slot clamp 6, and then the first slot clamp 5 and the second slot clamp 6 are unlocked and separated.
