Today we are going to focus on manufacturers to tell you about the relevant multi-leaf blast of air flow control valve structural features, to know that a majority of users of this knowledge is more concerned in understanding this knowledge, we can understand that it's safer applications. Let's look at the specific, as follows: Characteristic (l) of the air flow control valve in the unity of the whole blade width four sizes, leaf-shaped blades for diamond double positive outlet picture, between the blades soft lap 18,605,342,909, so airtight performance Good. Features (2) air volume control valve body architecture After 2 mm cold rolled galvanized sheet molding, carbon dioxide gas welding or welding by ordinary Q235 plate processing; blades with 1 mm cold rolled galvanized sheet for corrugated, two piece synthetic spot-square shaft inserted, or 2 mm cold-formed steel G235 pressure delivery outlet, single punching or welding circular interpolation square shaft axis. Features (3) of the valve sub-manual, electric pressure delivery outlet height, divided by the materials: iron, galvanized sheet, aluminum plate, stainless steel four, the same body structure and size specifications. For more information about multi-leaf outlet of knowledge that we will continue to bring you to organize, so stay tuned to draw attention to some of the leafy exhaust port wiring problem areas we want to focus on today explain to you about the multi-leaf smoke vents in this area knowledge. One of the more knowledge users need to understand that the majority of the problem is that some aspects of the multi-leaf junction exhaust port. For this knowledge could understand some promise, so today we give you stressed about, hope to better explain our cause everyone's attention, let's take a detailed look: for knowledge in this area, we first To understand the leafy exhaust port to pick four lines. The first is the control line, usually executed terminals 1,2 No. I control Zhang, connect DC24V power supply, it is the action (exhaust port open); then the signal is set to return line pressure delivery outlet, usually 4,5, 6 is a set of passive signal returns micro switch, 5 is a common point, and then returns the data signal with the requirements of the option of connecting 4 or 6. These are the areas of knowledge wiring to introduce us briefly about the multi-leaf smoke vents, and to learn more about this and we will continue to bring you to organize, so stay tuned.
