A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by José Antonio de Alzate y RamÃrez, a Mexican priest and scientist, who described the device in 1790 in the Gaceta de Literatura Méxicana.[1] It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped, hence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.

Pneumatic diaphragm pump internal structure
With the advent of the 21st century, earthshaking changes have taken place in many countries. For example, in our country, the material and living standards of people have greatly increased. However, for pneumatic diaphragm pumps, many people do not understand the situation because they are not people's daily necessities, resulting in a relatively small amount of information on the market. For manufacturers, The detailed description of the internal structure of the diaphragm pump can not only help users, but also promote these products. Pneumatic diaphragm pump internal structure diagram Next describes its internal structure: Pneumatic diaphragm pump is a new type of conveyor machinery, is currently the most novel kind of pump. Using compressed air as power source, for a variety of corrosive liquids. Aluminum pneumatic diaphragm pump pneumatic diaphragm pump which has four materials: engineering plastics, aluminum, cast iron, stainless steel. Pneumatic diaphragm pumps are based on different liquid media were nitrile rubber, neoprene, fluorine rubber, PTFE, polyhexamethylene. To meet the needs of different users. Placed in a variety of special occasions, used to pump a conventional pump can not be aspirated medium, have achieved satisfactory results. Diaphragm pump driven by compressed air. Through the air distribution valve and the reversing shaft, the most central components are: "air chamber", are set in the center of the pump. The medium flows through two confluence tubes and the pump housing, called "wetted parts." Normally Check Valves (ball or plate) are located at the manifold end and rely mainly on the ball for suction of liquid. During operation, the air distribution valve automatically distributes the compressed air to two separate air chambers. At the end of each diaphragm stroke, the reversing shaft changes direction and the air distribution valve distributes the compressed air into the other air chamber, moving the diaphragm in the opposite direction, thus creating a continuous alternating movement of the diaphragm on either side, thereby achieving Absorption and pressure of the role of the diaphragm pump is driven by compressed air, its quality requirements of the air must pass through the pneumatic triple filter to remove water, in addition to the role of air impurities to extend Valve, reversing shaft life. The check valve opens and closes as the medium passes through the diaphragm pump, which alternately fills and discharges inside each pump housing, and the check valve reacts to the pressure differential. Ball valve check Valves handle media with small particles, while check valve valves can handle media with soft particles close to the size of the pipe. Qigong diaphragm pump is a new type of conveying machinery. Nowadays it is a very novel pump equipment in our country. As its use continues to expand, its research and innovation have also attracted the attention of more professionals. I believe in the future its development deserves everyone's expectations.
