Understand the mechanical type of trap

Mechanical type also called float type, is the use of water and steam density difference, through the water level change, make the float elevator drive valve open or closed, to achieve the vapor barrier drainage. Mechanical type of trap super-cooling degree is small, not affected by working pressure and temperature change, there are water, no water in the heating equipment, can make the heating equipment to achieve optimum thermal efficiency. Maximum back pressure rate was 80%, the high quality of work, is the most ideal production process heating equipment of steam trap. Mechanical type of trap is freedom ball float, half ball float ball float, leverage, inverted bucket type, etc. Free ball float trap has simple structure, internal only one clinical activity components of fine grinding stainless steel hollow ball, is both a float and open-close part, no quick-wear part, long service life, YQ trap interior with Y series automatic air discharge device, is very sensitive and can automatic exhaust air, high quality of work. Equipment has just started work, air in the pipe after Y series automatic air discharge device, low temperature water into the steam trap, water level rise, the float rises, the valve opens and the condensate discharge rapidly, steam quickly into equipment, equipment rapidly, Y series automatic air discharge device of liquid thermal expansion, automatic air discharge equipment shut down. Trap began to work properly, the float along with the water level fluctuation, vapor barrier drainage. Free ball float trap seat total level in the following, form a water seal, no leakage, good energy saving effect. Minimum working pressure 0. 01 mpa, from 0. 01 mpa to the highest working pressure range is not affected by temperature and pressure fluctuations, continuous drainage. Can condensate saturation temperature, minimum degree of supercooling of 0 ℃, no water in the heating equipment, can make the heating equipment to achieve optimum thermal efficiency. Back pressure is greater than 85%, is the most ideal production process heating equipment of one of the trap. Free half ball float trap only one and a half ball float ball barrels for moving parts, opening down, the ball barrel is open-close part, and a seal. The entire sphere can be used for sealing, long service life, resistant to water hammer, no wearing parts, trouble-free, durable, no leakage of steam. Back pressure is greater than 80%, can the condensate saturation temperature, minimum degree of supercooling of 0 ℃, no water in the heating equipment, can make the heating equipment to achieve optimum thermal efficiency. When the device has just started, air in the pipe and low temperature condensate through a tube into the trap, bimetallic strip emptying elements within the valve barrel bounce off the ball, the valve opens, air and water flowing rapidly at low temperature. When steam into barrels a ball, the ball upward buoyancy bucket, at the same time, the temperature inside the valve, bimetallic strip emptying element contraction, the ball tong floats to the valve, the valve closed. When the ball the steam into the condensate inside the bucket, bucket loses buoyancy sinking, the valve opens and the condensate discharge quickly. When steam again into the ball barrels, the valve closed again, discontinuous and continuous work. Lever ball float trap basic characteristics the same as the free floating ball type, internal structure is floating ball connecting lever drives the valve core, as the condensate liquid level switch valve lift. Lever ball float trap using double seat increase water discharge, small size large displacement can be obtained, the biggest drain water quantity of 100 tons/hour, is the most ideal trap large heating equipment. Inverted bucket type steam trap is an inverted bucket inside for a liquid level sensitive parts, bucket downwards, inverted bucket connecting lever drives the valve core to open and close the valve. Inverted bucket type steam trap can exhaust air, not afraid of water hammer, the fouling resistance performance is good. The supercooling degree of small, leakage rate is less than 3%, maximum back pressure rate was 75%, the fitting is more, the sensitivity than free ball float trap. For inverted bucket type steam trap is established by steam upward buoyancy and close the valve, work pressure difference is less than 0. 1 mpa, not suitable for use. When the device has just started, air in the pipe and low temperature condensate into the trap, inverted bucket down on its own weight, inverted bucket connecting lever drives the valve core to open the valve, air and water flowing rapidly at low temperature. When the steam into the inverted bucket, the inverted bucket steam generate upward buoyancy, inverted bucket up connecting lever drives the valve core to close the valve. Inverted bucket to open a small hole, when a part of the steam from a small hole, the other part of the steam condensate, the bucket loses buoyancy, sink under their own weight and inverted bucket connecting lever drives the valve core to open the valve, work cycle, intermittent drainage. Combined superheated steam trap has two isolation valve cavity, two stainless steel tubes connected by upper and lower valve chamber, it is by the ball float and a combination of inverted bucket type steam trap, the valve structure of advanced and reasonable, in the heat, high pressure and small load working conditions, to be able to timely discharge superheat disappear when the formation of the condensate, effectively prevent leakage of superheated steam, high quality of work. Maximum allowable temperature is 600 ℃, the body as a whole stainless steel, the seat for hard alloy steel, long service life, is a special superheated steam trap, obtained two national patents, filled the domestic blank. When the condensate into the valve cavity, pair of valve ball float liquid level rise, floating ball closed into the steam pipe hole. Water by the water conduit to rise to the main valve cavity, inverted bucket by gravity drop, drives the valve core to open the main valve, discharge frozen water. Vice valve cavity when the water level falls, floating ball with the liquid level drops, the deputy valve to open. On the steam from the steam pipe into the inverted bucket, the main valve cavity upward buoyancy inverted bucket, bucket drives the valve core to close the main valve. Vice valve cavity when the water level rises, the next cycle began, intermittent drainage.
