One Question per Day in Applied Chemistry (9-7)
Thread Content
Leveraging knowledge related to applied chemistry, including (analytical chemistry, physical chemistry, and principles of chemical engineering), we are launching the \"One Question per Day\" activity; simply reply to get the question. To encourage ongoing participation from everyone! You get 3 wealth rewards just for participating! Answering 1 category correctly earns an additional wealth reward. I hope everyone will participate actively, learn together, and make progress together! ! ! How can valves be classified according to their purpose?
Valves can be classified by their purpose and function as follows: Control valves – mainly used to regulate parameters such as the flow rate and pressure of the medium. Including control valves, throttle valves, pressure relief valves, etc. Check valves – used to prevent the backflow of fluid. Including check valves of various structures. Shunt valves – used to separate, distribute, or mix fluids. Including distribution valves and steam traps of various structures, etc. Safety valves – used for safety protection when the pressure of the medium exceeds a certain level. Including various types of safety valves. Shut-off valves – mainly used to shut off or connect the flow of a medium. Including gate valves, globe valves, diaphragm valves, ball valves, plug valves, butterfly valves, plunger valves, etc.
Classified by the purpose of the valve: a) Shut-off type: used to shut off the medium in the pipeline. Such as: gate valves, globe valves, ball valves, plug valves, butterfly valves, etc. b) Check valves: used to prevent the backflow of the medium. For example: check valve c) For regulation: regulating pressure and flow. Such as: control valves, pressure reducing valves, throttle valves, butterfly valves, V-port ball valves, balance valves, etc. d) Distribution use: to change the flow direction of the medium in the pipeline and distribute the medium. Such as: distribution valves, three-way or four-way ball valves, plug valves, etc. e) For safety purposes: used for overpressure protection. Such as: safety valves, relief valves. f) Other special purposes: such as steam traps, air traps, drain valves, vent valves, breather valves, slag discharge valves, temperature control valves, etc.
Shut-off valves: mainly used to cut off or connect the flow of media. These include gate valves, globe valves, diaphragm valves, ball valves, plug valves, disc valves, plunger valves, ball plug valves, and metering needle valves. Control valves: Mainly used to regulate the flow rate, pressure, etc. of the medium. Including control valves, throttle valves, pressure relief valves, etc. Check valves: Used to prevent the backflow of fluid. Including check valves of various structures. Shunt valves: Used to separate, distribute, or mix media. Including distribution valves and steam traps of various structures, etc. Safety valves: Used for providing safety protection when the pressure of the medium exceeds a certain level. Including various types of safety valves.
It is divided into: 1. Shut-off valves: mainly used to shut off or connect the flow of the medium. These include gate valves, globe valves, diaphragm valves, ball valves, plug valves, disc valves, plunger valves, ball plug valves, and needle-type control valves. 2. Control valves: Mainly used to regulate the flow rate, pressure, etc. of the medium. Including control valves, throttle valves, pressure relief valves, etc. 3. Check valves: Used to prevent the medium from flowing in reverse. Including check valves of various structures. 4. Diversion valves: Used to separate, distribute, or mix fluids. Including distribution valves and steam traps of various structures, etc. 5. Safety valves: Used for providing safety protection when the pressure of the medium exceeds a certain level. Including various types of safety valves.
