Difference between exhaust throttle valve and intake throttle valve

The difference between exhaust throttle and intake throttle is as follows:

1. Different functions: exhaust throttle is used for double-acting cylinders, and intake throttle is generally used for speed control of single-acting cylinders, clamping cylinders and low-friction cylinders.

2. Speed difference: The exhaust throttle valve can adjust the opening speed of the throttle valve, thus changing the moving speed of the cylinder. This control mode to stabilize the piston operation is the most commonly used circuit. The intake throttle valve mainly relies on the expansion of compressed air to move the piston forward, so it is difficult to control the speed of the cylinder to achieve stability.

3. Different movement modes: after the exhaust throttle is adopted, the reversing valve is reversed, and the one-way valve on the intake side of the cylinder is opened, so that the rodless cavity of the cylinder can be inflated quickly, and the gas without the rodless cavity can only be discharged through the exhaust throttle; After the intake throttle speed regulation is adopted, the intake side check valve is closed, the exhaust side check valve is opened, the intake flow is small, the pressure in the intake chamber rises slowly, the exhaust is rapid, and the pressure in the exhaust chamber is very low.
