Lift check valves are also called piston check valves. They are essentially globe valves without the stem and top works, allowing the disc to respond to flow rates and direction. The disc has linear movement and is typically body-guided with conical seating surfaces. Springs can be added above the disc to provide more closure force when the disc returns to its closed position. Some manufacturers include externally attached equalizer piping to increase the disc opening with lower flows. The equalizer pipe is an open-pressure communication device that maintains equal pressure above the disc and in the piping downstream of the disc.

The seed germination box is also known as the germination box and the precision seed germination box. It is mainly used for germination of seeds, germination of seeds, constant temperature preservation of seeds, and germination rate of seeds. The seed germination box has the functions of light, hot and cold constant temperature, automatic humidification and dehumidification, automatic switching between day and night, and over-temperature protection.
What we are most concerned about is the performance of the germination box control system.
The control system of the seed germination box adopts microcomputer automatic control, control board integration, touch switch can be arbitrarily set for each test section running time, temperature, humidity, light value, to ensure the uniformity of the internal temperature of the box; large-screen liquid crystal display test cycle , Running time, actual temperature and humidity value, set temperature and humidity value, remaining time and light level; with cycle conversion function, with over-temperature and abnormal sensor protection to ensure the safety of instruments and samples; optional full-spectrum plant growth lamp, It is conducive to the growth of plants and improves disease resistance. It has the function of automatic power-off memory and power-off time compensation. It can continue the original working state after a power failure.
Therefore, the seed germination box combined with a stable, safe and intelligent control system not only saves manpower, material resources and financial resources for work, but more importantly it can provide a seed culture room with high quality, high efficiency and high yield.
