[0002] A butterfly valve, also known as a flap valve, is a regulating valve with a simple structure. It can be used for the on-off control of low-pressure pipeline media. A butterfly valve refers to a valve whose closing member (valve disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing. The combination between the valve shaft and the disc can be called a valve core assembly. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media, and mainly plays a role of cutting off and throttling in pipelines.

[0003] When the butterfly valve is installed and connected to the pipeline, the butterfly valve flange and the pipeline flange need to be aligned and then fixed with bolts. However, for large-sized and large butterfly valves that are not installed on the ground, it is difficult to repeatedly adjust the position or height of the butterfly valve during the alignment process, resulting in a very time-consuming and labor-intensive assembly and installation process.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3 A flange-assembled multifunctional split butterfly valve comprises a valve body 1 and a base 7 arranged directly below the valve body 1. The lower end of the base 7 is rotatably connected with four rectangularly distributed universal wheels 9 for easy movement. A second support plate 2 is fixed at the lower end of the valve body 1 for supporting the valve body 1. A first support plate 5 is arranged at the lower end of the second support plate 2 for supporting the valve body 1. Two guide rods 8 are slidably inserted at the lower end of the second support plate 2 for keeping the second support plate 2 linearly lifted and lowered. The lower end of the guide rod 8 is fixedly connected with the upper end of the first support plate 5.

[0020] In this embodiment, a first adjustment mechanism is provided between the first support plate 5 and the second support plate 2. The first adjustment mechanism includes a bidirectional screw rod 3 provided between the first support plate 5 and the second support plate 2, which is used to drive the second support plate 2 to rise and fall. The two ends of the bidirectional screw rod 3 are respectively inserted into the first support plate 5 and the second support plate 2. The bidirectional screw rod 3 is threadedly connected to the first support plate 5 and the second support plate 2. A first rudder-type handle 4 is fixedly sleeved on the bidirectional screw rod 3 to facilitate the user to rotate the bidirectional screw rod 3.

[0021] In this embodiment, the lower end of the base 7 is provided with a groove corresponding to the first support plate 5, and the lower end of the first support plate 5 movably extends into the groove. One side of the groove is rotatably connected with a support 6 for supporting and driving the first support plate 5 to rotate. The other side of the groove is provided with a connecting groove. One end of the support 6 penetrates the first support plate 5 and is rotatably connected to the inner wall of the connecting groove. The support 6 and the first support plate 5 are fixedly connected.

[0022] In this embodiment, a second adjustment mechanism is provided in the connecting groove, and the second adjustment mechanism includes a worm wheel 12 fixedly sleeved on the pillar 6, which is used to drive the pillar 6 to rotate. A worm 13 meshing with the worm wheel 12 is rotatably connected to the bottom of the connecting groove, which is used to drive the worm wheel 12 to rotate. The upper end of the worm 13 passes through the base 7 and is fixedly connected to a second rudder-type handle 10, which is used to facilitate the user to manually rotate the worm 13. The worm 13 is rotatably connected to the base 7.

[0023] In the present embodiment, firstly, by setting the base 7, the first support plate 5, the second support plate 2 and the universal wheel 9, the user can move the valve body 1 conveniently, and align the valve body 1 with the pipe flange conveniently. The first rudder-type handle 4 is manually rotated to drive the bidirectional screw 3 to rotate. The bidirectional screw 3 drives the second support plate 2 and the valve body 1 to rise and fall through the action of thread engagement, so that the user can align the valve body 1 with the pipe flange conveniently. At the same time, the second rudder-type handle 10 is manually rotated to drive the worm 13 to rotate. The action of the engagement between the worm 13 and the worm wheel 12 drives the support 6 to rotate. The support 6 drives the first support plate 5, the second support plate 2 and the valve body 1 to adjust the inclination angle, so as to further facilitate the user to align the valve body 1 with the pipe flange.
