Hot working principle of the static type of trap and classification

Trap is the use of steam and condensate temperature difference caused by heat element variant or expansion drive heart valve opening and closing of the valve. Hot static type of trap super-cooling degree is larger, general degree of supercooling of 15 to 40 degrees, it can use a part of the condensate sensible heat, always have high temperature condensate before valve, no leakage, energy-saving effect is remarkable. Is in the steam pipe, heating pipe, small heating equipment, heating equipment, temperature requirements is not high, small heating equipment, the most ideal trap. Hot static type of trap with bellows, bellows type, double metal plate. Bellows trap is the main action of element metal film box, filled with a kind of gasification temperature is lower than the water saturation temperature of liquid, have open valve temperature below the saturation temperature 15 ℃ and 30 ℃ two to choose from. Bellows trap particularly sensitive reaction, not afraid of cold, small size, resistant to overheating, can be installed at any position. Back pressure is greater than 80%, can not condensate gas, bellows solid, long service life, convenient maintenance, using range is very wide. Just starting, piping in low temperature condensate, the liquid in the bellows condensation state, the valve is in open position. When the temperature of the condensed water is increasing, membrane inside the liquid evaporated, membrane combined internal pressure rise, diaphragm drives the valve core to close the direction, before condensate saturation temperature, steam trap began to close. Bellows with the steam temperature control valve switch, vapor barrier drainage effect. Bellows type steam trap valve core stainless steel corrugated tube filling a vaporization temperature lower than that of water saturation temperature of the liquid. Change with steam temperature control switch valve, the valve is equipped with adjusting bolt, can be used according to need to adjust the temperature, the average degree of supercooling adjusting range below the saturation temperature 15 ℃ - 40℃。 Back pressure is greater than 70%, is not afraid of cold, small size, can be installed at any position, can not condensate gas, long service life. Appear when the device is started, pipe cooling water, liquid in a condensed state, corrugated tube valve core under the elasticity of spring, in an open position. When the temperature of the condensed water is increasing, the corrugated tube liquid evaporated inflation, higher internal pressure, deformation and elongation, drives the valve core to close the direction, before condensate saturation temperature, steam trap began to close, with the steam temperature control valve switch, vapor barrier drainage. Bimetallic strip trap are the main components of bimetallic strip temperature sensing element, lift heat steam temperature, deformation, push the valve core switch valve. Bimetallic type steam trap is equipped with adjusting bolt, can be used according to need to adjust the temperature, the general super-cooling degree below the saturation temperature 15 ℃ - adjustable range 30 ℃, the back pressure is greater than 70%, can not condensate gas, not afraid of cold, small size, resistant to water hammer, resistance to high pressure, can be installed at any position. Bimetallic strip have fatigue sex, need frequent adjustments. When the device just starting, pipeline in low temperature condensate, bimetallic strip is flat, valve core under the elasticity of spring, the valve is in open position. When the condensate temperature rise gradually, bimetallic strip thermal element began bending deformation, and the valve core to the closed position. Before the condensate saturation temperature, steam trap began to close. Bimetallic strip with the steam temperature control valve switch, vapor barrier drainage.
