【control valve】Valve body type selection: There are many types of valve bodies for regulating valves, and commonly used valve body types include ① straight through single seat ② straight through double seat ③ angular ④ diaphragm ⑤ small flow ⑥ three-way ⑦ eccentric rotation ⑧ butterfly ⑨ sleeve type ⑩ spherical, etc. When selecting a regulating valve, the following considerations can be made: (1) Valve core shape and structure: mainly based on the selected flow characteristics and unbalanced forces. (2) Wear resistance: When the fluid medium is a suspension containing high concentrations of abrasive particles, the internal material of the valve should be hard. (3) Corrosion resistance: Due to the corrosive nature of the medium, it is advisable to choose valves with simple structures. (4) Temperature and pressure of the medium: When the temperature and pressure of the medium are high and vary greatly, valves with valve cores and seats that are less affected by temperature and pressure changes should be selected. When the temperature is ≥ 250 ℃, a radiator should be added. (5) Prevent flash evaporation and cavitation: Flash evaporation and cavitation only occur in liquid media. In the actual production process, flash evaporation and cavitation can cause vibration and noise, shortening the service life of valves. Therefore, when selecting valves, precautions should be taken to prevent flash evaporation and cavitation.

Overview of Pneumatic Thin Film High Pressure Angle Regulating Valve:

Pneumatic thin film high-pressure angle regulating valve is a special valve designed for use in high-pressure systems. After being connected to pneumatic or electric (power to gas converters) regulating instruments, it is widely used in industries such as fertilizers, petrochemicals, power plants, and light industry for automatic regulation and remote control of production processes. Pneumatic thin film high-pressure angle regulating valve uses changing signal pressure to change the flow energy cross-section of the valve, thereby achieving a change in medium flow rate and completing the adjustment of required parameters (such as pressure, flow rate, temperature, liquid level, etc.).

【control valve】It consists of an electric or pneumatic actuator and a regulating valve. Regulating valves are divided into electric regulating valves, pneumatic regulating valves, and hydraulic regulating valves (self operated regulating valves). Regulating valves are used to regulate the flow rate, pressure, and liquid level of the medium. According to the signal from the regulating position, the opening of the valve is automatically controlled to achieve the regulation of medium flow rate, pressure, and liquid level. Regulating valves are usually divided into two types: straight through single seat regulating valves and straight through double seat regulating valves. The latter has the characteristics of large flow capacity, small imbalance, and stable operation, so it is usually particularly suitable for situations with high flow rate, high pressure drop, and low leakage. The flow capacity Cv is one of the main parameters for selecting a regulating valve. The definition of the flow capacity of a regulating valve is: when the regulating valve is fully opened, the pressure difference between the two ends of the valve is 0.1MPa, and the fluid density is 1g/cm3, the flow rate per hour of the regulating valve is called the flow capacity, also known as the flow coefficient, expressed in Cv, with the unit of t/h. The Cv value of the liquid is calculated according to the following formula.
