Top Vacuum Socre brings you a new solution for optimizing valve selection. In vacuum systems, vacuum system components used to change the direction of airflow, adjust the volume of airflow, cut off or connect pipelines are called vacuum valves. The functions of vacuum valves in vacuum systems are: switching air paths, changing the flow route of airflow; controlling the volume of airflow, adjusting the vacuum degree; and quantitatively inflating. Vacuum valves mainly include vacuum angle valves, vacuum ball valves, vacuum butterfly valves, vacuum diaphragm valves, vacuum gate valves, and vacuum globe valves. Different types of vacuum valves have different applications. Below, we will discuss the characteristics and common areas of use of different types of valves such as gate valves, globe valves, butterfly valves, and ball valves. When configuring and selecting vacuum valves, it is necessary to consider the minimum pressure difference and high flow resistance of components within the molecular flow range. In addition, the valve body and valve seat require the minimum leakage rate. The lubricant on the vacuum side of moving parts in the valve must be suitable for the required pressure and temperature range, or overall exposure to high or ultra-high vacuum should be avoided as much as possible. The minimum harmful (dead) space and large flow conductance are important, especially in the molecular flow range.

1. Select the valve type based on the vacuum level The first principle in valve selection is vacuum level matching. Under different vacuum ranges, there are significant differences in gas flow state, leakage sensitivity, and material outgassing behavior. If the valve level is insufficient, it will become a performance bottleneck for the entire system.

Semiconductor RF chips and their vacuum coating processes

The core function of the ‌ radio frequency chip is to handle the transmission and reception of radio signals, enabling efficient data transmission and connection of wireless communication devices ‌. It is widely used in fields such as mobile phones, the Internet of Things, automotive radars, base stations, and defense systems. The radio frequency Chip (RF Chip) serves as the "signal translator" and "transmission bridge" of wireless communication systems. Its core mission is to achieve the transmission and reception, modulation and demodulation, and signal optimization of high-frequency electrical signals. It converts the digital signals processed by the baseband chip into RF signals that can be transmitted through antennas, while simultaneously receiving external RF signals and restoring them to digital signals. From mobile phone calls to satellite communications, from Internet of Things transmission to car radars, the signal transmission in all wireless connection scenarios relies on the precise operation of radio frequency chips.

What are the process technologies of argon arc welding?

IG welding (Tungsten Inert Gas welding) sounds quite high-tech, and indeed it is an oxygen-free welding method with relatively high requirements. In principle, it involves introducing argon, a gas with stable properties, to expel air and continuously cover the welding area. This prevents the metal in the welding zone from coming into contact with air, avoiding reactions between oxygen, nitrogen, and other gases in the air with the electric arc and the welding area, thereby achieving a high-quality welding effect.
