Analysis by adjusting the throttle
Propane Control Valve characteristics shows that the flow through the Propane Control Valve depends on the size of the physical characteristics of the flow Propane Control Valve and fluid control Propane Control Valve and flow coefficient KV with the Propane Control Valve opening change, and thus the physical properties of the fluid constant, flow relational expression can be expressed as
Taking into account the volume of syrup spray job is about 1: 500, a mixture of pesticides accounted for a smaller share of medicine, therefore, may be a mixture of syrup density approximation for the density of water, which in the process of mixing traditional Chinese medicine water mixture density a constant. Binding of formula (2) shows, the flow rate through the flow control Propane Control Valve pesticide only with the pressure downstream of the flow regulating Propane Control Valve and the patio heater control valveopening degree concerned. Therefore, as long as the flow of traffic through the establishment of the relational model calibration regulating Propane Control Valve downstream pressure and Propane Control Valve opening between, you can come through the control Propane Control Valve opening line detection and control of the actual flow of liquid, enabling online real mix drugs. In addition, the spray pressure is generally between 0.2 ~ 0.5MPa, in spray application process, spraying droplets into the atmosphere of 1 atm (about 0.1MPa), even if the line pressure loss is ignored, the maximum differential pressure regulating Propane Gas Control Valvedownstream to 0.4MPa, therefore, the following main conditions for pressure is less than 0.4MPa study started.
