Problems solved by technology

[0004] The disadvantage of the existing flow control device is: since the pressure in the metering tank will change correspondingly when the material is fed or discharged, when the pressure in the metering tank is relatively high, the flow rate of the material will decrease at the same speed and time of the metering pump. It must be relatively large. When the pressure in the metering tank is small, the flow rate of the material must be small at the same speed and time of the metering pump, resulting in inaccurate metering of the metering pump; Strict, so that part of the material flows back from the circulation pipe to the metering tank, resulting in inaccurate metering by the metering pump, so the metering accuracy of this flow control device is not high

Embodiment Construction

[0011] The flow control device of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, the flow control device includes a metering tank 1. The metering tank 1 is connected to the metering pump 2 through a pipeline. The metering pump 2 is connected to the pouring valve 3 through a pipeline. The pouring valve 3 is connected to the metering tank 1 through a circulation pipe 4. The pouring valve 3 includes a hollow cylindrical shell 31, the side of the shell 31 is provided with a feed port 32, one end of the shell 31 is provided with a discharge port 33, and the other end of the shell 31 is provided with a circulation Port 34, and the inside of the housing 31 is provided with a pouring rod 35. When the pouring rod 35 moves telescopically, the feed port 32 communicates with the circulation port 34 or the discharge port 33 respectively, and the circulation pipe 4 and the pouring valve 3 Ci...
