Description

TECHNICAL FIELD

[0001] The utility model relates to the field of stop valve, concretely is a stop valve for pipeline. BACKGROUND

[0002] In the pipeline system, the stop valve as an important fluid control element is widely used in various occasions for cutting off or regulating the fluid flow in the pipeline.

[0003] The current stop valve design is often single function, only simple opening and closing operation can be realized, cannot satisfy the flexible control demand of water flow switching distribution in multiple pipeline systems, such as irrigation system, cooling system or water supply network etc., often needs to distribute single water source to multiple water outlets, needs to use multiple individual stop valves to control each water outlet, this method not only increases the complexity and cost of the system, but also occupies a large space, brings inconvenience to installation and maintenance. SUMMARY

[0004] In order to overcome the above-mentioned insufficient, the utility model provides a stop valve for pipeline.

[0005] The utility model takes the technical scheme:

[0006] A stop valve for pipeline, including the valve body, the valve body is the shell structure, the both sides of valve body are circular ring shape, the top of valve body is circular, the top of valve body is round plate, the inside of valve body is hollow, the bottom center of valve body is fixedly connected with water inlet pipe, the outer wall of valve body is fixedly connected with three water outlet pipes, three water outlet pipes are evenly distributed at equal interval angle, the valve body has the valve core, the valve core is annular with notch, the notch of valve core is one third of integral annular, the valve core is slidably connected with the inner wall of valve body, the top center of valve body is rotatably connected with valve rod, the bottom end of valve rod penetrates round plate to the inside of valve body, the bottom end of valve rod is rotatably connected with round plate, the outer wall between the bottom end of valve rod and the outer wall of valve core is fixedly connected with multiple connecting plates, connecting plates are distributed radially, the top end of valve rod is fixedly connected with rotating disc.

[0007] The utility model has the advantages of:

[0008] The utility model can easily switch water outlet pipe by rotating the rotating disc, realize the flexible control of water flow, make the user control the distribution of water flow, the outer wall of valve body is annular, three water outlet pipes are evenly distributed at equal angle, make the whole stop valve structure compact, occupy small space.

[0016] like Figures 1-6 As shown: A gate valve for pipelines includes a valve body 1, which is a shell structure. The valve body 1 has two annular sides and a circular top. The top of the valve body 1 is a circular plate 8. The valve body 1 is hollow inside. A water inlet pipe 2 is fixedly connected to the center of the bottom of the valve body 1. Three water outlet pipes 3 are fixedly connected to the outer wall of the valve body 1. The three water outlet pipes 3 are evenly distributed at equal intervals. The valve body 1 contains a valve core 4, which is an annular shape with a notch. The notch of the valve core 4 is one-third of the entire annular shape. The valve core 4 slides against the inner walls of the two sides of the valve body 1. A valve stem 5 is rotatably connected to the center of the top of the valve body 1. The bottom end of the valve stem 5 passes through the circular plate 8 into the interior of the valve body 1. The valve stem 5 is rotatably connected to the circular plate 8. Multiple connecting plates 6 are fixedly connected between the outer wall of the bottom end of the valve stem 5 and the outer wall of the valve core 4. The connecting plates 6 are radially distributed. A turntable 7 is fixedly connected to the top end of the valve stem 5.

[0017] Before operation, the position of the notch in the valve core 4 determines which outlet pipe 3 is open. Since the notch in the valve core 4 is one-third of the overall ring and the three outlet pipes 3 are evenly distributed at equal angles, in the initial state, the notch in the valve core 4 will be aligned with one of the outlet pipes 3, so that the outlet pipe 3 is connected to the inlet pipe 2, allowing water to flow through.

[0018] When it is necessary to switch the outlet pipe 3, the operator rotates the turntable 7 at the top of the valve stem 5. The rotation of the turntable 7 drives the valve stem 5 to rotate, which in turn drives the valve core 4 to slide on the inner wall of the valve body 1 through multiple radially distributed connecting plates 6.

[0019] As the valve core 4 rotates, its notch gradually moves away from the previously aligned outlet pipe 3 and simultaneously moves towards another outlet pipe 3.

[0020] During movement, the valve core 4 will temporarily block all the water outlets 3 at the same time, and then the notch is aligned with the new water outlet 3, so that the water outlet 3 is communicated with the water inlet 2.

[0021] When the notch of the valve core 4 is completely aligned with the new water outlet 3, water will flow out through the water outlet 3, and the other two water outlets 3 are completely blocked by the valve core 4, and no water flows out.
