The function of the cylinder throttle valve, how to adjust the cylinder throttle valve

The function of cylinder throttle valve

Throttle valves are divided into two types: limited inlet throttling and limited outgoing throttling. The general inlet mark is ----i, and the limit outlet mark----O. The throttle valve (it is a kind of joint) can also be installed separately.

Cylinder throttle valveThe main function is to adjust Since there are two speeds, one must be for adjusting the feed speed and the other for adjusting the return speed. One is to adjust the feed speed, which is the speed of delivery. The other is to adjust the return speed of thecylinder.

How to adjust the cylinder throttle valve

1. The speed of the cylinder can be achieved by adjusting the flow rate of the intake air, such as regulating valves, throttle valves, etc.

2. If different speeds are required, multiple air paths can be used to achieve it.

3. The combined output of multiple air circuit controls can achieve a variety of cylinder speeds.

In-depth analysis of cylinder throttle valve

Cylinder throttle is an essential accessory of the cylinder. Most people rarely pay attention to this standard part. When selecting, they only care about whether to choose ø4 or ø6, and then Or if the bore diameter is too large, choose a ø8 one. Is there anything else I should pay attention to?

Intake throttling VS exhaust throttling

Throttle valves are divided into intake throttling and exhaust throttling. As the name implies: one throttles when the air is in, and the other throttles when the air is out. If the airflow is from the threaded end to the air pipe end, and the adjustment nut has obvious effect after adjustment, it is an exhaust throttle valve. On the contrary, it is the intake throttle valve (many people go to the site and do not know how to adjust the cylinder speed).

When the air is throttled, the pressure in the exhaust chamber is small (connected to the atmospheric pressure), and the gas in the air inlet chamber is restricted. The air flow is small, the initial pressure is small, and the cylinder When the load is large, it will crawl and then rush. When the air is throttled, the pressure in the exhaust chamber will not suddenly drop to zero due to the action of the limited flow valve. The pressure in the air inlet chamber is the same as that of the air source, which can form a more stable pressure difference and achieve better speed regulation effects. When common single-acting cylinders or air blowers use exhaust throttling, the throttle valve will not work at all (this is very common, not to mention assembly, but not engineering), because the flow is limited by the return stroke of the cylinder. The return stroke of the cylinder is generally unloaded.

Pressure regulating cap locking function

You may be familiar with this. As shown in the picture at the beginning, some brands have a pressure regulating cap locking function. After the cylinder speed is adjusted, in some places with high speed requirements, in order to prevent the vibration from changing over time or other personnel accidentally touching it, using this kind of speed regulating valve will, of course, be more expensive. In general, use the ordinary one (Figure 2, easy to change) can.



Selection of throttle valve diameter

The thread specification of the throttle valve is selected according to the cylinder, and the connecting diameter of the speed control valve is selected according to the corresponding< a href="https://www.diancifa.cc/" target="_blank">CylinderCylinder diameter selection. Generally, the recommended diameter is listed at the beginning of the brand manual, you can refer to the selection. . Avoid choosing a trachea diameter that is too small, which may cause the cylinder to fail to move or crawl.
