What is the working principle of the pressure gauge globe valve Please tell us about the pressure in

When the water surface in the toilet exceeds the high point of the S-bend, the siphon phenomenon is formed, which can pump the water and dirt from the toilet bowl together. Toilets, officially known as toilets, are buckets with lids for urinating and urinating. The invention of the toilet is known as a great invention, which solved the problem of people eating and drinking in and out of Lazar. >>>More

Make the most of the water pressure of the city's tap water and apply the principles of fluid mechanics. >>>More

The suction cup can suck the wall is to squeeze the air inside the suction cup when extruding the suction cup, so that the air pressure inside the suction cup is far less than the external air pressure, so that there is great pressure on the external surface of the suction cup to press the suction cup on the wall, under this huge pressure, if the wall surface is not smooth enough, so that the outside air will be pressed into the inside of the suction cup through the small gap in the connection between the suction cup and the wall, the internal air pressure will increase, and the external atmospheric pressure will not change, so that the difference between the internal and external air pressure will decrease, and the pressure on the outer surface of the suction cup will decrease, Suction cups are naturally easy to drop. >>>More

The paint booth is an equipment that provides a special environment for painting operations, and is an environmentally friendly product for painting products, and is used to treat the exhaust gas and paint mist emitted by painting. Its function is to limit the paint mist in the painting process to a certain area for filtration. Painting in the water curtain spray room, its working environment is good and clean, protecting the safety and health of the paint master, bringing a safe, healthy, bright and comfortable working environment; At the same time, it can meet the needs of the coating operation for the temperature, humidity, illumination and cleanliness of the environment; It can also control the waste discharge generated in the coating operation and protect the surrounding environment from pollution. >>>More

After the 220V AC power passes through the bulb H and the rectifier bridge, it becomes a DC pulsating voltage, which is added to the VS and R branches of the thyristor as a forward bias voltage. During the day, when the brightness is greater than a certain extent, the photodiode D presents a low-impedance state of 1K, so that the triode V is cut-off, and its emitter has no current output, and the unidirectional thyristor VS is blocked because there is no trigger current. At this time, the current flowing through the bulb H does not emit light. >>>More
