Boiler cascade water reducing valve advantages

Boiler water temperature control valve can be used for large and medium-sized generating units, the main steam boiler and reheat steam temperature control of the water required for the cooling water flow rate, it is one of the key power plant valve. stn water regulating valve is a kind of anti-cavitation multi-stage throttling control valve, also known as high-pressure regulating valve, which is a novel structure of the control valve. Cascade water reducing valve has the following advantages: 1. Fluid step-down, the fluid direction is constantly changing, stn water regulating valve with cascade structure, the fluid through the tortuous passage, the purpose is to reduce the flow of energy consumption, Prevent liquid cavitation. Increase the flow resistance, control the flow rate to prevent cavitation damage. Allow pressure drop 25mpa. 2. Multi-level throttling: 4 throttling at high flow rate, 5 throttling at low flow rate, to reduce fluid erosion on the spool surface. 3. Throttling surface and the sealing surface separately, the valve core and the valve sleeve surface hardening treatment, the hardness reaches hrc70 or so, close tight, long life. 4. There is a big gap on the surface of the valve core. The fluid contains solid particles such as 2 ~ 3mm welding slag and the valve core will not be stuck and the movement is flexible. 5 flow adjustment features good adjustment range (about 60 ~ 70%). The control valve is a patented product, our patent registration number is no.15739, many power plants have successfully used this multi-stage throttling control valve.

High Flow Peristaltic Pump

The working principle of a High Flow Peristaltic Pump like a snake swallowing an egg. The hose is constantly squeezed through the roller to make the hose generate pressure and push the liquid forward. Our designers make the Peristaltic pump head and hose fit perfectly by designing precise roller size and pump head structure. So as to achieve the purpose of accurate liquid metering transmission or filling

1. Clean and pollution-free: the fluid only passes through and touches the peristaltic pump hose.
2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. With stop valve function, no siphon, no seals, stop valve and check valve function.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
