Valves are the most common equipment in chemical enterprises and play a great role. They seem to be simple and easy, but in the actual operation process, they also need to meet the relevant technical requirements, otherwise they will cause safety accidents. Only the valves related to our liquid level appearance are introduced here, and other equipment is not analyzed.
The most common valves on our level gauges are: blowdown valves, exhaust valves and globe valves (ball valves and gate valves). Of course, the first two valves are brought by the level gauge according to the user's requirements when leaving the factory, and the shut-off valve is used to connect the level gauge and the equipment, of course, they do not require some working conditions, but as a professional instrument manufacturer, we recommend installing them, which can facilitate subsequent maintenance.
Here are a few types of globe valves:
1. Ball valve: generally divided into pneumatic ball valve, manual ball valve and electric ball valve, wear-resistant, good sealing performance, light switching force and long service life.
2. Globe valve: It is a forced seal valve, which is simpler in structure than gate valve, more convenient in maintenance, and has greater flow resistance.
3. Gate valve: when opening and closing, the sealing surface is easy to wear, difficult to maintain, and the scale is large. The structure is messy.
