I would like to ask what the hole in this control valve is for?
Thread Content
I would like to ask everyone: In Figure 1, there are three identical small holes in a week’s time – what is the purpose of these? Thank you for the guidance
This hole doesn’t even have threads. Is there an exhaust hole on the cylinder? By the way, are you from Changlian?
It’s not a Changlian model; the top of the cylinder doesn’t have an exhaust port, and there are three ports at the bottom (on the left side of the diagram).
Top post, keep it from sinking; Learn along the way *:lol
It must be the exhaust hole; I can think of nothing else. The volume on the spring side is relatively large, so faster exhaust during air supply allows for quicker operation. There definitely can’t be any more holes in the air inlet line at the top
It’s the breathing hole on the spring side; the absence of such a hole can cause abnormal valve operation
How many years have you been working with instruments? It shouldn’t be long before we make contact
I used to work at Changlian before; the equipment there looks quite similar
It must be the exhaust vent. In the past, I encountered situations where the exhaust from the large valves wasn’t working properly; the solution was to use a drill to make holes at the bottom of the cylinder, making sure to take precautions to prevent water leakage!!
