One of the video capture card technical parameters is the video frame rate. This parameter is very important. The following small series first briefly introduces what is the frame rate of the video capture card. Frame rate of the video capture card The number of frames per second (fps) or frame rate represents the number of times the graphics processor can update every second while processing the field. High frame rates for smoother, more realistic animations. In general, 30fps is acceptable, but improving performance to 60fps can significantly improve the sense of interaction and realism, but in general, more than 75fps is generally not easy to notice a significant increase in fluency. If the frame rate exceeds the screen refresh rate, it only wastes the ability to process graphics, because the monitor cannot be updated at such a fast speed that the frame rate exceeding the new rate is wasted. Through the above understanding of what is the frame rate of the video capture card, when selecting the video capture card, you must first understand the resolution and frame rate of the video device output, so that you can choose the capture card that suits you. Otherwise, the frame rate of the video capture card cannot reach the output device frame rate, and preview and capture will not be possible.
Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.
Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services. Angle Valves, Angle Globe Valves, Brass Angle Valve, Zinc Angle Valve ZHEJIANG KINGSIR VALVE CO., LTD. , https://www.kingsir-valves.com
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
