Description

technical field [0001] The invention relates to a steam trap with visible liquid level, which is applied to heating equipment using water vapor as heat carrier. Background technique [0002] At present, steam traps are widely used in petrochemical, food and pharmaceutical, power plants and other heating or heat tracing equipment and pipelines that use water vapor as the heat carrier. The function of the steam trap is to discharge the condensed water in the steam system as soon as possible, and at the same time prevent the leakage of water vapor to the greatest extent. The function of the steam trap is simply to drain water and block steam. After the water vapor absorbs heat, it condenses into water. If the condensed water of water vapor cannot be discharged in time, the heat absorbed will cause the temperature to drop rapidly, affecting the continuous and stable supply of heat energy, resulting in Production cannot proceed normally.

Problems solved by technology

The mechanical type is also called the float type, which utilizes the density difference between condensed water and steam, and through the change of the condensed water level, the float lifts and drives the valve disc to open or close, so as to achieve the purpose of blocking steam and draining water. Occasionally, there is a phenomenon of jamming, which causes the valve flap switch to be untimely or insensitive, resulting in energy waste or poor drainage, so that the water vapor condensate cannot be discharged in time, affecting the normal heat exchange of the heat exchange equipment, and causing instability to production; The power type is based on the principle of phase change, relying on the difference in flow rate and volume change when steam and condensed water pass through, so that different pressure differences are generated between the upper and lower sides of the valve plate, which drives the valve plate to switch the valve. The working power of the thermal power type steam trap comes from steam. Therefore, the waste of steam is relatively large; the thermostatic type uses the temperature difference between steam and condensed water to cause deformation or expansion of the temperature sensing element to drive the valve core to open and close the valve. The temperature sensing element is fatigued after long-term operation, resulting in poor drainage of condensate or steam leak waste

[0004] It can be seen that while the existing steam traps discharge water vapor condensate, there are more or less water vapor leakage phenomena, especially during the use of the steam trap, the wear and deformation of the internal components are the main causes of water vapor leakage during the use of the steam trap. biggest cause of leaks
