The thermal power disc drain valve uses the difference in water flow rate between steam and condensate to drive the disc opening and closing.
○ Flow rate difference between steam and condensate water
○ Pressure changes generated by secondary steam
○ Rated pressure: PN63
○ Maximum allowable pressure of valve body: 6.27MPa/200 ℃
○ Maximum allowable temperature of valve body: 450 ℃/2.6MPa
○ Factory steam action test:>3 times/1.6MPa
○ Maximum working pressure: 4.2MPa
○ Maximum operating temperature: 350 ℃
○ Factory cold test pressure: 9.5MPa
○ Air test: 2.0MPa
○ The valve body and valve cover are made of forged steel, cast steel, and stainless steel.
○ The valve disc and seat are made of martensitic stainless steel.
○ After heat treatment and aging treatment, they remain unchanged and wear-resistant under high temperature and high pressure, thereby improving the service life of the drain valve.
○ Stainless steel insulation sleeve, used for isolating and reducing heat loss, and eliminating ineffective actions.
○ The internal structure of the flow channel is strictly designed according to the ○ Bernoulli equation, and the structure is reasonable.
○ The built-in filter ensures that the drain valve operates in a clean environment.
○ The back pressure rate can reach 80% or higher.
○ In order to eliminate low-temperature condensed water with high undercooling, customization is required.
○ Steam main and heat tracing pipelines quickly eliminate condensed water to prevent erosion
○ Sensitive opening and closing control is required in superheated steam systems due to the absence of liquid water
○ Compact installation scenarios for small steam equipment such as disinfection cabinets, ovens, etc
○ High temperature pipeline space restricted hydrophobic nodes in the paper and textile industries
○ Outdoor or corrosive environments require maintenance free high reliability applications
The thermal power disc drain valve uses the difference in water flow rate between steam and condensate to drive the disc opening and closing.
The thermal power disc type drain valve relies on the principle of fluid dynamics to automatically open and close, with a simple structure, shock resistance, and no need for external energy.
