Product surface description:
Directly buried insulated drain joint refers to a steel pipe fitting that, after being processed by insulation technology, ensures that the temperature inside the working steel pipe meets or meets the requirements for use under different working environments and external media. Directly buried insulated drain joint is one of the indispensable fittings in steam pipelines. The drain joint is also known as prefabricated insulation and drainage joint, which is moisture-proof, drainage and external anti-corrosion. Steel pipes with good insulation are coated with external anti-corrosion treatment. Working principle of steam pipeline drain joint: when the pipe inside the drain joint is cold

Description :
Directly buried insulated drain joint refers to a steel pipe fitting that, after being processed by insulation technology, ensures that the temperature inside the working steel pipe meets or meets the requirements for use under different working environments and external media.
Directly buried insulation drain joint is one of the indispensable fittings in steam pipelines. The drain joint is also known as prefabricated insulation and drainage joint, which is moisture-proof, drainage and external anti-corrosion. The working principle of well insulated steam pipeline drain joint
When condensed water flows into hole A in the drainage section, the valve plate is pushed open by the pressure of the condensed water. The water passes 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 are unobstructed, and the valve plate is normally open, continuously discharged. 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 lower pressure at the outlet orifice, the steam specific volume increases sharply with the 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 in the chamber and quickly closing the valve plate downwards to block steam. As the thermal power type steam trap can seal after the valve plate is closed, it can prevent the discharged condensed water from flowing back into the working pipe. Therefore, there is no need to install a check valve behind the thermal power type steam trap.
