The difference between cylinder exhaust throttle valve and intake throttle valve

The difference between cylinder exhaust throttle valve and intake throttle valve

1. Exhaust throttling: After the exhaust throttle valve adopts exhaust throttling, the reversing valve is reversed.Cylinder< /strong>The one-way valve on the intake side opens to quickly inflate the rodless cavity of the cylinder. The gas in the rodless cavity can only pass through the throttle on the exhaust side. Flow valve exhaust. By adjusting the opening speed of the throttle valve, the movement speed of the cylinder can be changed. This control method ensures stable piston operation and is the most commonly used circuit. Exhaust throttling should be used for double-acting cylinders. The throttling method of rotation in the hydraulic system of the electric jack is selected based on the actual situation of the customer.

2. Intake throttling: After using intake throttling to adjust speed, the intake side one-way valve is closed and the exhaust side one-way 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. The expansion of compressed air 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 stabilize with this throttling method. Generally used for speed control of single-acting cylinders, clamping cylinders and low-friction cylinders.

1. Different functions< /p>

Exhaust throttling is used for double-acting cylinders;
Inlet throttling is generally used for speed control of single-acting cylinders, clamping cylinders and low-friction cylinders.

2. Different speeds
Exhaust throttle adjusts the opening speed of the throttle valve to change the movement speed of the cylinder. This control method ensures stable piston operation and is the most commonly used circuit.
Intake throttling mainly relies on the expansion of compressed air to move the piston forward, so this throttling method is difficult to control The speed of the cylinder reaches stability.

3. Different exercise methods
After exhaust throttling is adopted, after the reversing valve is reversed, the one-way valve on the intake side of the cylinder opens, and no flow is directed to the cylinder. The rod cavity is quickly inflated, and the gas in the non-rod cavity can only pass through the exhaust sideThrottle valveExhaust.
After using intake throttle speed regulation, the one-way valve on the intake side is closed and the exhaust When the side check valve is open, the intake air 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.

Enter How to distinguish between air throttle valve and exhaust throttle valve?

Exhaust throttling is generally used for air pressure
Air intake throttling is generally used in hydraulics
