DETAILED DESCRIPTION

[0020] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the controllable multi-pipeline ball valve comprises a valve body 1, left and right valve rods 3 and 4 are respectively arranged on the left and right sides of the front side of the valve body 1, the surfaces of the left and right valve rods 3 and 4 are fixedly connected with limiting plug shells 8, a fixed shell 5 is fixedly connected with the middle part of the front side of the valve body 1, a positioning spring 17 is movably connected with the inner cavity of the fixed shell 5, support plug plates 12 are fixedly connected with the left and right sides of the positioning spring 17, positioning plug shells 11 are fixedly connected with the left and right sides of the bottom of the valve body 1, a liquid collecting shell 6 is inserted into the bottom of the positioning plug shell 11, and an optical liquid sensor 10 is fixedly connected with the bottom of the inner cavity of the liquid collecting shell 6.

[0022] The number of the limiting plug shells 8 is four, which are arranged on the inner part and the bottom of the surfaces of the left and right valve rods 3 and 4, and the outer sides of the support plug plates 12 extend into the inner cavities of the limiting plug shells 8 through the fixed shell 5.

[0023] A threaded joint 2 is welded with the top of the valve body 1, and a control module 9 is fixedly connected with the bottom of the liquid collecting shell 6. A clamping hole is arranged on the front side of the inner cavity of the positioning plug shell 11, and a warning light strip 7 is embedded into the top of the front side of the liquid collecting shell 6. The liquid collecting shell 6 comprises a shell body 18, the left and right sides of the top of the shell body 18 are fixedly connected with connecting cross plates 19, the top of each connecting cross plate 19 is fixedly connected with a connecting plug plate 20, and a positioning clamping block 16 is fixedly connected with the outer side of each connecting plug plate 20.

[0024] Sliding openings 14 are arranged on the left and right sides of the front side of the fixed shell 5, and push plates 15 are fixedly connected with the front sides of the support plug plates 12 through the sliding openings 14. A support plate 13 is fixedly sleeved with the rear side of the surface of the fixed shell 5, and the rear side of the support plate 13 is fixedly connected with the valve body 1.

[0025] In actual manufacturing, the main water pipe is connected with the threaded joint 2, and the branch water pipes are connected with the two sides of the valve body 1.
