Mechanical type, also known as float type, is the use of the density difference between condensate and steam, through the condensate level changes, so that the float lift valve to open or close, to block steam drainage purposes. Mechanical type of small degree of supercooling traps, free from pressure and temperature changes, the water that is row, no water heating equipment, heating equipment can achieve the best heat transfer efficiency. Maximum back pressure ratio of 80%, high quality workmanship, the production process is the ideal heating device steam trap. Mechanical trap with free float, free half float, lever float, inverted bucket, etc. 1, free float trap: Free float trap has a simple structure, the internal only a fine moving parts Grinding stainless steel hollow float, both the float and the opening and closing pieces, non-wearing parts, long service life, "Silver Ball" card traps with Y series automatic exhaust air device is very sensitive and can automatically discharge air, High quality of work. When the equipment is just started to work, the air in the pipeline is exhausted by the Y series automatic exhaust air device. The low temperature condensate water enters the steam trap, the condensate water level rises, the float rises, the valve opens, the condensate water rapidly discharges and the steam quickly enters Equipment, equipment, rapid heating, Y series of automatic exhaust air temperature of the liquid expansion of the device, automatic exhaust air device is turned off. Traps began to work normally, the float with the condensate level rise and fall, block steam drainage. Free float ball valve seat is always below the liquid level to form a water seal, no steam leakage, energy saving effect. Minimum working pressure 0.01Mpa, from 0.01Mpa to the maximum operating pressure range from the impact of temperature and pressure fluctuations, continuous drainage. To the saturation temperature condensate water, the minimum undercooling is 0 ℃, heating equipment without water, can make the heating equipment to achieve the best heat transfer efficiency. Back pressure rate greater than 85%, is the production of process heating equipment, one of the best trap. 2, free half-float trap: free half-float trap only one half-ball bucket for the moving parts, opening down, the barrel is the opening and closing pieces, but also seals. The entire spherical surface can be sealed, long service life, water resistance, no wearing parts, trouble-free, durable, no steam leakage. The back pressure rate is greater than 80%, to the saturation temperature condensate water, the minimum undercooling is 0 ℃, heating equipment without water, can make the heating equipment to achieve the best heat transfer efficiency. When the device is just started, air and low temperature condensate in the pipeline enter the steam trap through the launch tube. The bimetallic emptying element in the valve bounces the bucket open, the valve opens, and the air and low temperature condensate drain rapidly. When the steam enters the bucket, the bucket produces upward buoyancy, while the temperature inside the valve rises, the bimetallic emptying element contracts, the bucket drifts toward the valve port, and the valve closes. When the steam inside the bucket becomes condensed water, the bucket loses its buoyancy and sinks, the valve opens and the condensate drains quickly. When the steam enters the barrel again, the valve is closed again, intermittently and continuously. 3, Lever Float Traps: The basic features of Lever Float Traps are the same as the free float type. The internal structure is a floating ball connecting lever that drives the valve core to open and close as the liquid level of condensate rises and falls. Leveraged float traps use double seats to increase the condensate displacement to achieve a small volume displacement, the maximum hydrophobic capacity of 100 tons / hour, is the ideal large-scale heating equipment traps. 4, inverted bucket trap: inverted bucket traps inside is an inverted bucket for the level of sensitive parts, hanging bucket opening down, inverted bucket connected to the lever to open the spool valve. Upside-down bucket trap to the air, not afraid of water hammer, anti-fouling performance. Undercooling is small, the leakage rate is less than 3%, the maximum back pressure rate of 75%, more connectors, the sensitivity of free float ball traps. Because inverted bucket steam trap is closed by steam buoyancy valve, working pressure less than 0.1MPA, not suitable for use. When the device is just started, air and low temperature condensate in the pipeline enter the steam trap, the inverted bucket falls by its own weight, the inverted bucket connects the lever to drive the valve core to open the valve, and the air and low-temperature condensed water are rapidly discharged. When the steam enters the inverted bucket, the steam in the inverted bucket generates upward buoyancy, and the inverted bucket rises to connect the lever to drive the valve core to close the valve. Inverted bucket has a small hole, when part of the steam discharged from the hole, the other part of the steam condensate, inverted bucket loses its buoyancy, by its own weight to the sink, inverted bucket connected to the lever to open the valve spool, the cycle Work, intermittent drainage. 5, combined superheat steam traps: Combined superheated steam traps have two isolated valve cavity, the two stainless steel pipe connected to the upper and lower valve cavity, which is a combination of float and inverted bucket traps, the valve The structure is advanced and reasonable. Under the working conditions of overheating, high pressure and light load, the condensate formed when the superheated steam disappears can be discharged in time, effectively preventing overheated steam leakage and high working quality. The maximum allowable temperature of 600 ℃, the valve body is all stainless steel, the valve seat is carbide steel, long service life, is a steam trap for superheated steam, made two national patents, to fill the gap. When the condensate into the lower chamber, the deputy valve float with the liquid level rise, the float closed into the steam hole. The condensate water rises to the main valve cavity through the water inlet pipe. The inverted bucket falls down by its own weight and drives the valve core to open the main valve and discharge the condensate. When the vice cavity of the condensate water level drops, the float drops with the liquid level, deputy valve open. The steam enters into the inverted bucket inside the main valve cavity through the steam inlet pipe, the uplift bucket produces upward buoyancy, and the inverted bucket actuates the valve core to close the main valve. When the secondary valve cavity condensate water level then rise, the next cycle began again, intermittent drainage.
