Description

Technical Field

[0001] The utility model relates to the technical field of steam traps, in particular to a steam trap filtering and anti-blocking structure. Background Art

[0002] A steam trap, also known as a steam trap or drain valve, is a valve used in situations where it is necessary to prevent the medium from leaking out of the equipment. Its main function is to control the flow of liquid or gas to achieve the purpose of draining water. The working principle of the steam trap is to use the pressure difference of liquid or gas to open or close the valve. When a certain amount of condensed water or air accumulates in the pipeline, the steam trap will sense the pressure difference and automatically open the valve to discharge the accumulated liquid or gas. When the discharge is completed, the steam trap will automatically close the valve to maintain the sealing of the system. However, when the existing steam trap discharges gas or liquid, when the gas enters the steam trap, impurities will inevitably exist in the gas and liquid. When it is discharged, the internal components of the steam trap will be contaminated, which will affect the drainage efficiency of the steam trap and increase the wear and tear of the internal components of the steam trap, causing friction between the components to cause the steam trap to fail.
