Description

Flow dividing valve
Technical Field
The invention relates to a flow dividing valve, in particular to a flow dividing valve used on a water quality monitoring ship.
Background
The water quality monitoring is a process for monitoring and measuring the types of pollutants in the water body, the concentrations and the variation trends of various pollutants and evaluating the water quality condition. The monitoring range is very wide, and the monitoring range comprises uncontaminated and contaminated natural water (rivers, lakes, seas and underground water), various industrial drainage and the like. The main monitoring projects can be divided into two main categories: one is a comprehensive index reflecting the water quality conditions, such as temperature, chroma, turbidity, pH value, conductivity, suspended matters, dissolved oxygen, chemical oxygen demand, biochemical oxygen demand and the like; the other is some toxic substances, such as phenol, cyanogen, arsenic, lead, chromium, cadmium, mercury, organic pesticides and the like. In order to objectively evaluate the water quality of rivers and oceans, it is sometimes necessary to measure the flow velocity and flow rate in addition to the above-mentioned monitoring items. At present, an unmanned ship is often used for water sample collection and water quality detection in water quality monitoring, water in a water area is collected into a detection cavity on the ship through a sampling pump on the unmanned ship, and then the sampled water in the detection cavity is detected through a sensor on the unmanned ship, for example, Chinese patent document CN207510670U discloses the unmanned ship for water quality monitoring. Most of the water quality detection sensors are electrochemical sensors, and chemical substances in the sensors are consumed in the long-time use process, so that the accuracy of the sensors is reduced, and the sensors need to be replaced after being used for a period of time. On the existing unmanned ship, because various sensors are uniformly arranged in the detection cavity, the sampled water is consumed by the sensors after entering the detection cavity. However, in some water areas, various data of water quality are not required to be monitored, and only certain water quality data, such as ph value of water quality, are required to be collected, which causes unnecessary loss of other sensors. Therefore, each sensor can be independently arranged in one detection cavity, sampling water can be injected into one or some detection cavities according to needs to obtain corresponding water quality data, and therefore the water pumped by the water sampling pump needs to be distributed into the corresponding detection cavities by using the distribution valve.
