Disc steam trap is based on thermal power Bernoulli principle, the use of steam and condensate different thermodynamic properties, kinetic and potential movement caused by pressure changes. So that the valve actuator pressure changes from top to bottom, start to open and close the valve, so as to achieve the purpose of blocking gas drainage. Features 1. Small size, light weight, unrestricted installation location. 2. All are made of stainless steel parts, durable and corrosion-resistant. 3. In the outdoor afraid of freezing, the ability of water hammer resistant overheating. 4. undercooling 8 ℃, steam leakage rate of less than 3% of the actual displacement, maximum back pressure of 50%. 5. Simple structure, easy installation and maintenance. Works within the trap with a valve piece, both sensitive to the actuator member is action. When the device starts, the pipe cooling off condensate, condensate open the valve by operating pressure, rapid discharge. When the condensation water discharge is completed, the steam enters the trap, the rapid expansion of the volume of steam, steam condensate flow rate greater than the valve sheet to produce pressure up and down, quickly close the valve in the steam flow rate of suction. When the valve is closed, both sides of the valve under pressure, the valve below the force area is less than the above force area, due to the pressure inside the trap steam chamber from the vapor pressure, so the valve on top of the force is greater than the following, valves tightly closed. When the steam chamber inside the steam trap cooled to condensate, steam room inside the pressure disappears. Condensate pushed by work pressure valves, condensate and continue to discharge cycle work, intermittent drainage.
