Does the control function of the valve ensure that the valve has sufficient flow capacity?

The flow regulating and pressure regulating valve is also known as a piston multi-function control valve, because it has a variety of control functions (such as water level control function, pressure reduction control function, pressure sustaining pressure relief control function, flow control function, etc.), it can play a role in No cavitation, no turbulence, no vibration, impact resistance and other effects.

The flow regulating and pressure regulating valve has a good energy dissipation effect on the fluid under small flow conditions, effectively preventing cavitation; under large flow conditions, the valve can reduce part of the energy of the fluid and retain part of the energy of the fluid. Ensure that the valve has sufficient overcurrent capacity. Its main advantages are as follows: accurate control of flow can be achieved, and constant flow can be maintained; adjustment within a large pressure difference range can be achieved to maintain pressure stability after the valve; manual and electric control methods can be selected, and electric flow regulating and pressure regulating valves can also be realized. With remote control, operators can make high-precision adjustments as needed without having to visit the site.

The regulating valve has a good fluid energy dissipation effect on the valve under small flow conditions, effectively preventing cavitation; when the flow rate is large, the valve energy can reduce the energy of the fluid and retain the energy of the fluid to ensure that the valve has enough energy. overcurrent energy. Its main advantages are as follows: to achieve precise control of flow, which can maintain constant flow; large pressure adjustment range, to maintain stable pressure behind the valve; two manual and electric control modes can be selected, power flow and pressure regulating valve can be remotely controlled, and the operator There is no need to go to the site, and high-precision adjustments can be made as needed.

The leakage of the valve often occurs on the packing, flange seal and valve body. The long-term leakage of the valve can cause the erosion of the valve stem and the flange sealing surface, which can make the valve scrapped, and the loss of the medium fluid will increase the consumption of the power plant. , the cost rises, and the economic benefit declines. If the medium fluid is toxic, flammable, explosive, corrosive, etc., external leakage occurs, casualties such as poisoning, fire, explosion, etc. are likely to occur, and the corrosion rate of plant equipment will be accelerated, shortening its service life, polluting the surrounding environment in serious cases, and destroying power production and damage people's health.
