The invention provides a multi-channel flow adjusting valve and a liquid supply system, and relates to the technical field of liquid supply equipment. The multi-channel flow adjusting valve comprisesa valve seat, multiple first valve mouth assemblies, multiple second valve mouth assemblies and multiple adjusting parts. The valve seat is provided with a backflow channel, multiple valve element channels and multiple adjusting channels used for communicating the backflow channel with the valve element channels. The multiple first valve mouth assemblies and the multiple second valve mouth assemblies are arranged on the valve seat and are in one-to-one communication through the valve element channels. The multiple adjusting parts are arranged on the valve seat in a manner of being capable of moving up and down and are in one-to-one correspondence to the multiple adjusting channels. The adjusting parts are provided with cooperation portions matched with the adjusting channels, and liquid passing gaps are clamped between the cooperation portions and the adjusting channels. The adjusting parts can move up and down relative to the valve seat so as to adjust the sizes of the liquid passinggaps. In addition, the liquid supply system comprises the above flow adjusting valve, and the quantity of each path of output liquid can be finely adjusted through the adjusting parts.
Description
technical field [0001] The invention relates to the technical field of liquid supply equipment, in particular to a multi-channel flow regulating valve and a liquid supply system. Background technique [0002] Soft capsule pill press is a common pharmaceutical equipment, which is equipped with a flow regulating valve to adjust the amount of liquid supplied. [0003] At present, most of the flow regulating valves used in soft capsule pill presses are slideway metering pump structures, and the pipelines controlled by the slideway metering pumps are used to calculate the capacity of the device. However, as time changes, the inner cavity of the slideway of the metering pump is prone to wear and tear, and the measured capacity error is relatively large, which will lead to the problem of unequal drug amounts loaded by different soft capsule balls in practical applications. In view of this, the inventor proposes the present application after studying the prior art. Contents of th...
