It can monitor and control the water flow and is used as a device for dividing and converging or switching the flow direction of the medium in pipelines in coal chemical industry, petrochemical industry, rubber, papermaking, pharmaceutical industry, etc.

[0003] After searching, a Chinese patent discloses an intermediate pipe for sampling a water supply pipe (publication number CN 110565746B). This patented technology uses a water turbine to drive the impeller to rotate to stir the water in the intermediate pipe into a vortex, pick up the precipitated impurities, and transport the sample water through the guide blades. Precipitation is not easy to occur during the transportation process. When the control valve is opened, the sample water can be discharged from the drain pipe. Sampling is very convenient, and through stirring and rotating transportation, precipitation is not easy to occur for water sampling.

The lateral end of the closing plate 3011 close to the annular plate 3015 is fixedly connected with a rubber sealing plate 3025, and the lateral end of the rubber sealing plate 3025 is fixedly connected with a handle 3024. The rubber sealing plate 3025 fits closely with the inner wall of the guide frame 3023. The rubber sealing plate 3025 can increase the connection sealing performance to prevent water leakage. The handle 3024 can be simply pulled to increase the entry depth of the rubber sealing plate 3025 and increase the sealing performance. The inner wall of the water intake pipe 3014 is fixedly connected with a blocking step 3022, and the inner wall of the water intake pipe 3014 is rotatably connected with a switch leaf door 3021.

The water storage volume in the water storage box 405 can be expanded by sliding the movable bottom plate 401, and at the same time, the internal cavity air pressure is prevented to block the water flow from entering, so that the water flow can quickly enter the water storage box 405 to complete the sampling and collection. The water outlet component 404 is composed of a sealing plug and a water outlet hole, which can control the discharge of water in the water storage box 405. For those skilled in the art, In other words, the water outlet component 404 is a prior art and will not be described in detail herein.
