How can external button operation of an explosion-proof distribution box be satisfied?

We can make a small opening (window) on the explosion-proof distribution box, which precisely exposes the part of the instrument that needs to be displayed. Below are several small buttons. I believe everyone now understands what this is for. These can be pressed, and above and below there are indicator plates: the upper one displays the function of the instrument, which is also its name, while the lower one displays the functions of the instrument buttons. There are also several buttons here, each corresponding to several functions. Inside, we can see the assembled components, and we can remove one piece to show it.。

First, here is a piece of glass. This is the button we just mentioned, and its interior. The edge portions are all sealed with this adhesive, epoxy resin adhesive. There is a surrounding frame on the side, and then we add this pressing frame to hold down the glass. Here there are support pillars that prop up the instrument. In this way, when we press the button from the outside, it also operates the interior, and it aligns exactly. Of course, this glass is not ordinary glass; it undergoes tempering treatment. It must withstand certain thermal shock, meaning that under high-temperature conditions, it must not crack and must not affect the function of the explosion-proof electrical equipment.

Secondly, it must withstand a certain impact force, so its strength is very critical; ordinary glass will not do. The adhesive also has certain requirements for high and low temperatures, as it needs to be heat-resistant and cold-resistant. This is the entire instrument assembly. As you can see, this instrument assembly not only solves the display and operation issues of the instrument, but also meets explosion-proof standard requirements, and is aesthetically pleasing. What an excellent solution it is.。

The above is how to meet the requirements for external button operation on an explosion-proof distribution box.？Content introduction. For more related information, please visit Hualong Explosion-proof at www.hlfbdq.com/.
