The Triple Eccentric Butterfly Valve, which makes use of a metal seat, is therefore able to withstand a greater amount of pressure, compared to Resilient Seated Butterfly Valve. The seal of the eccentric disc could be either metal/Graphite multi-layer design, or fully metal-to-metal design. The multi-layer design could achieve zero leakage and simple maintenance, while the metal-to-metal design is more reliable in higher temperature and pressure. Basically speaking, triple Eccentric Butterfly Valve is both applied in shutoff or throttling service.

Common led strips usually do not need to install cooling equipment, because the led strip screen is not very long, and usually installed LED modules are semi-outdoor modules, there is void heat can be dissipated directly, so there is no need for heat treatment.
Indoor monochrome led screen does not need heat dissipation, because the indoor led monochrome screen module is also magnetic type, there is a gap between the module and the module, the heat can be directly dispersed, so no need to install cooling equipment.
Outdoor led large screen must install cooling equipment. Outdoor led screen has these characteristics, first of all, waterproof is very important, led outdoor large screen installed on the column, hanging on the external wall of the building, some are inlaid installation, the seal must be very strict, or water or moisture, This can lead to poor circuit contact on the led screen resulting in a short circuit risk. Second, the outdoor led large screen brightness is high, the brightness must be greater than the illumination to display a clear picture, it means that the power than the indoor led large screen power, the power generated by the heat is also great, so the outdoor full color led screen must Install cooling equipment. Some people say that there is no need to install. If it is not installed, the main effect is that the internal temperature of the screen is high, which will lead to premature aging of the screen components and shorten the life. And the LED screen will also have the risk of IC breakdown in the short term. There are two ways to dissipate heat. First, the LED screen area is less than 20 square meters. Convection fans can be used to install outside blinds to prevent rain from splashing into the screen. More than 20 square meters, to install air conditioning to cool, an average of 20 square meters led screen 1 2P air conditioning, then 100 square meters of led screen will install 5 sets of 2P air conditioning.
"Led screen how to deal with heat problems" We all know that led screen is divided into indoor led display, outdoor led large screen, led full color screen, monochrome led screen, graphic led screen. Led big screen since it is electrical, there is power, there are components, it will certainly produce heat. So what kind of temperature is more appropriate in the heat, led large screen should be maintained at what temperature is considered reasonable. Let's focus on the following for reference.
