Description

Technical Field

[0001] This utility model relates to the field of throttle valve technology, specifically a novel electric throttle shut-off multifunctional throttle valve. Background Technology

[0002] A throttle valve is a valve that controls fluid flow by changing the throttling cross-section or throttling length. Specifically, when fluid passes through a throttle valve, the internal channel area of ​​the valve decreases, causing the fluid velocity to increase, thereby controlling the flow rate. Throttling valves also feature a wide flow rate adjustment range and smooth pressure difference changes, which makes them widely used in industrial production.

[0003] Considering that throttle valves are frequently adjusted during use and flow control needs to be ensured, failure to adjust the valve in time may cause changes in flow rate due to increased fluid intake. When the flow rate changes, turbulence may occur, which can prevent the fluid from flowing out smoothly, leading to internal blockage. Blockage increases internal pressure. Although the equipment itself can withstand high pressure, continuous exposure to a high-pressure environment will also lead to increased wear and tear and reduced service life.
