Manual throttle valve
5 month agoWorking Principle
The throttle valve mainly relies on the axial movement of the valve stem to change the flow area between the valve core and the valve seat, thereby adjusting the flow and pressure of the fluid. When the valve stem moves downward, the valve core approaches the valve seat, the flow area decreases, the resistance to the fluid increases, and the flow and pressure decrease; conversely, when the valve stem moves upward, the flow area increases, and the flow and pressure increase.
Features
High flow regulation accuracy: It can accurately adjust the fluid flow to meet the strict requirements of different process processes for flow. By finely adjusting the flow area between the valve core and the valve seat, the flow can be controlled to change within a smaller range.
Large pressure loss: Since the fluid needs to pass through a narrow flow channel when passing through the throttle valve, it will produce a large pressure loss. When selecting a throttle valve, it is necessary to reasonably evaluate the impact of pressure loss on the system based on specific process requirements and system pressure conditions.
Simple structure: The structure of the throttle valve is relatively simple compared to other valves. It is mainly composed of valve body, valve core, valve seat, valve stem and operating mechanism. There is no complex internal transmission mechanism, so the manufacturing and maintenance costs are low and the reliability is high.

Application
Petrochemical industry: In the process of petroleum refining and chemical production, throttle valves are often used to control the flow and pressure of various fluids, such as crude oil, gasoline, diesel, various chemical raw materials and products. For example, in the reflux pipeline of the distillation tower, the flow of the reflux liquid can be accurately controlled by the throttle valve to ensure the stability of the distillation process.
Power industry: In thermal power plants, throttle valves are used to control the flow and pressure of media such as steam and water. For example, in the steam inlet pipeline of the steam turbine, the throttle valve can be used to adjust the steam flow and pressure entering the steam turbine, thereby controlling the speed and output power of the steam turbine.
Aerospace field: In the fuel system, hydraulic system and air conditioning system of the aircraft, throttle valves are used to accurately control the flow and pressure of various fluids. For example, in the fuel supply system of an aircraft, the throttle valve can accurately adjust the fuel flow according to the working status of the engine to ensure the normal operation of the engine.
