The grooved bright rod soft sealing gate valve adopts a new type of steel pipe connection, also called clamp connection, which has many advantages. The design specification of automatic sprinkler system proposes that the connection of the system piping should be connected by grooved joints or threaded and flanged joints; for pipes with a diameter equal to or greater than 100mm in the system, flanges or grooved joints should be used in sections. connection.
The open-bar groove soft sealing gate valve has six characteristics:
1. All specifications, large inventory, fast delivery, low price, is your ideal first product.
2. Structural Science: Flat Design.
The bottom of the groove soft sealing gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris accumulation, so that the fluid is unobstructed.
3. Gate rubber: The whole gate is covered with rubber. It is made of high quality rubber and has good elasticity! Durable.
4. Shell material: made of precision ductile iron, once formed.
Traditional cast iron gate valves often cause breakage due to foreign objects hitting, collision or heavy pressure. Since Hebei Hongqiu valve soft seal gate valve body is changed to ductile iron, this situation can be greatly reduced.
5. The valve body is sprayed with 5005, the coating thickness is not less than 250μm. It can prevent corrosion and rust of the valve body and can be used in sewage system.
6. The internal structure of the open-bar groove soft sealing gate valve is accurate in size. The precise geometrical dimensions allow the valve body to be sealed without any finishing.
OLED is organic light-emitting diode (D1de), which has the characteristics of self illumination, high brightness, wide viewing angle, high contrast, flexibility, low energy consumption and so on. Therefore, it has been widely concerned. As a new generation of display mode, it has gradually replaced the traditional liquid crystal display, and is widely used in mobile phone screen, computer display, full-color TV and so on. OLED display technology is different from traditional liquid crystal display technology. It does not need backlight. It uses very thin organic material coating and glass substrate. When there is current passing through, these organic materials will emit light. However, as organic materials are easy to react with water vapor or oxygen, OLED displays have high requirements for packaging.
