Please help me provide a quick-opening sanitary grade manhole
Thread Content
The diameter of the cylinder I designed is 350mm. It is a container that is often opened, so a quick-opening manhole-like device needs to be installed on the cylinder. Please ask an expert on this kind of drawing to send me a copy. I would be very grateful!
It seems that someone posted a picture of a quick manhole, please search it and take a look.
Search the Internet for "quick hand hole opening". There are many drawings for you to choose from.
The sanitary grade is different from the general ones. Its surface treatment is very strict and its cutting is small. Nowadays, most pharmaceutical equipment factories or standard parts suppliers sell them. You can ask about them. Just buy the standard one.
Strictly speaking, the hole in the cylinder with a diameter of 350 is not called a manhole, but a hand hole. I am engaged in crafts, you can press 1: I will draw a three-dimensional diagram for you at 1 scale. To make the diagram, you need to find an equipment person. If you need it, just say it, it's best to send me a text message, I'm afraid I'll forget. This post was last edited by Diao Dayu on 2009-4-13 13:42 ]
