Description

Technical Field

[0001] This utility model relates to the field of butterfly valves, specifically to a short flange type marine butterfly valve. Background Technology

[0002] Short flange type marine butterfly valves are commonly installed on fluid transmission pipelines in ships to control the opening and closing of pipelines and the flow of fluid. For example, patent application number 202021554679.6 discloses a short flange type Japanese standard marine butterfly valve, including a valve body with flanges at both ends. The flanges have equidistant connecting holes around the valve body. A lifting handle is horizontally fixed to the upper side of the front and rear outer walls of the valve body. Connecting sleeves are fixedly connected to the upper side of both ends of the valve body. Positioning bolts are horizontally slidably inserted into the connecting sleeves. The outer wall of the positioning bolts is threaded. A linkage rod is movably connected to the end of the positioning bolt near the center of the valve body. A linkage ring is horizontally arranged above the valve body and is movably connected to the end of the linkage rod. A first telescopic rod is vertically fixedly connected to the outer wall of the uppermost part of the flange body, and a spring is sleeved on the upper end of the first telescopic rod. A connecting rod is horizontally fixedly connected to the upper end of the first telescopic rod. A locking pin is vertically fixedly connected to the lower side of the end of the connecting rod away from the center of the valve body. A support sleeve is fixedly connected to the outer wall of the flange body at the position of the first telescopic rod. A fixed slide rod is horizontally slidably inserted into the support sleeve, and the end of the fixed slide rod away from the center of the valve body is inserted into the connecting rod. Threaded connecting cylinders are fixedly connected to both the front and rear sides of the linkage ring. A fixed screw is vertically inserted into the lifting handle. It has the following advantages: by lifting the entire valve body with the handles on the front and rear sides, the flanges at both ends of the valve body are aligned with the flanges at the ends of the connecting pipes, and the connecting holes are aligned. Then, by pulling down the linkage ring with one finger holding the handle, the linkage ring is opened by the linkage rod, and the positioning bolt is slid laterally through the connecting hole on the flange body and the hole on the connecting pipe flange, without the need to support it with your hand.

[0023] In use: First, install the first mounting ring 3 and the second mounting ring 4 on the outside of the ship pipe 34 using the first screw 5 and the first screw sleeve 6. Then, use screw 10 to install the additional block 9 on the side of the first mounting ring 3. Next, install the lower first movable block 13 and the first screw sleeve 14, and the front and rear second movable blocks 17 and the second screw sleeve 18 in sequence. Then, place the valve body 1 between the two ship pipes 34, and then install the upper first movable block 13 and the first screw sleeve 14. At this time, the support blocks 19 and the balls 20 on the upper and lower sides and the front and rear sides can support the valve body 1. Then, rotate the second screw 30 of the positioning mechanism 23 so that the end of the second screw 30 moves out from between the first limit blocks 32.

Then use bolts to fix the mating flange bodies together to complete the installation of the valve body 1. This makes it easier and more convenient to operate because the connection holes of the flange body of this product do not need to be held by hand while aligning with the connection holes of the flange body of the marine pipeline 34. Then slide the auxiliary plate 22 to abut against the side of the bolt and rotate the second screw 30 so that the end of the second screw 30 moves out between the second limit blocks 33. The spring 26 will return to its original position, so that the end of the positioning head 28 can be inserted into the positioning groove at the corresponding position of the first movable block 13 and the second movable block 17. Then rotate the second screw 30 in the opposite direction so that the end of the second screw 30 is between the first limit blocks 32, so that the installed bolts are not easy to fall off, thereby improving the stability of the valve body 1 after installation.
