Steel jacket, steel insulation, steel pipe drain trap

Steel sleeve steel insulated steel pipe steam trap is a customized product, and users must provide drawings when placing orders. Generally, drawings are provided by the design institute.

The function of the steel jacket insulated steel pipe drain is to automatically and quickly discharge condensed water from the pipeline and prevent steam leakage. At the same time as discharging condensed water, remove residual air and other non condensable gases in the pipeline.

Working principle diagram of steel jacket, steel insulation, steel pipe trap

When the condensate flows into hole A, the valve plate is pushed open by the condensate pressure, and the water flows through the annular groove B and is discharged from the small hole opened downwards. During this flow process, due to the constant specific volume of condensed water, the air and condensed water flow smoothly, and the valve plate remains open for continuous discharge. When steam enters, the valve plate is opened, and the steam flows from hole A under the valve plate to the outlet through groove B. Under the action of lower pressure at the outlet orifice, the steam specific volume increases sharply with pressure drop, and the steam flow velocity under the valve plate increases sharply, causing the static pressure under the valve plate to decrease. At the same time, steam is forced to rush into the control chamber above the valve plate through the gap between the valve plate and the valve cover, establishing a sufficiently high pressure inside the chamber and quickly closing the valve plate downwards to block steam. Due to the sealing effect of the thermal power type steam trap after the valve plate is closed, it can prevent the discharged condensed water from flowing back into the working pipe, so there is no need to install a check valve behind the thermal power type steam trap.
