What are the differences between an exhaust throttle valve and an intake throttle valve?
1 Answers
The differences between an exhaust throttle valve and an intake throttle valve are as follows: 1. Different functions: The exhaust throttle is used for double-acting cylinders; the intake throttle is generally used for speed control in single-acting cylinders, clamping cylinders, and low-friction cylinders. 2. Different speeds: Adjusting the opening of the exhaust throttle valve can change the movement speed of the cylinder. This control method ensures stable piston operation and is the most commonly used circuit. The intake throttle mainly relies on the expansion of compressed air to move the piston forward, making it difficult to control the cylinder's speed stably with this method. 3. Different movement methods: After using the exhaust throttle, when the directional valve changes direction, the one-way valve on the intake side of the cylinder opens, quickly filling the rodless cavity with air, while the gas in the rodless cavity can only exhaust through the throttle valve on the exhaust side. After using the intake throttle speed control, the intake side one-way valve closes, the exhaust side one-way valve opens, the intake flow is small, the pressure in the intake cavity rises slowly, the exhaust is rapid, and the pressure in the exhaust cavity is very low.
