[0025] Please see Figure 1-6 This utility model provides a technical solution:

[0026] A compact steam trap with a heat dissipation structure includes a valve body 1 with a heat dissipation structure and a valve cover 2, and a temperature-controlled self-operated thermostatic element 3. The valve body 1 is characterized by: the valve cover 2 being bolted to the upper end; the thermostatic element 3 being fixedly connected inside the valve cover 2; a valve seat 4 being fixedly connected to the outer side of the valve body 1; a drain hole 5 being fixedly connected to the outer side of the valve body 1; a float ball 6 being provided inside the valve body 1; a filter screen 7 with a ball cover being fixedly connected to the upper end of the inner side of the valve body 1; a cleaning device 8 being fixedly connected to the inner side of the valve body 1; and a water inlet being provided inside the valve body 1.

[0027] As a further implementation of the above technical solution: the valve body 1 is provided, with a limiting ring 81 fixedly connected to the inner side of the valve body 1, and a cleaning plate 83 slidably connected to the inner side of the valve body 1. The bottom of the cleaning plate 83 is installed inside the mounting groove 82, and the cleaning plate 83 and the limiting ring 81 are parallel to each other. The vertical cross-section of the cleaning plate 83 is U-shaped. This arrangement makes the overall structure more reasonable. The cleaning plate 83 can rise and fall with the condensate level, thereby effectively cleaning the inner wall of the valve body 1 and preventing dirt from adhering to the surface of the valve body 1.

[0028] As a further implementation of the above technical solution: a number of friction holes 84 are provided, the cross-sectional shape of the friction holes 84 is set to rhombus, the friction holes 84 are arranged in an array, and the friction holes 84 are arranged in a circle on the upper end of the cleaning plate 83. The friction holes 84 can pass through the friction filter screen 7, thereby effectively cleaning the surface of the filter screen 7.

[0029] As a further implementation of the above technical solution: by setting an anti-clogging device 89, there are several anti-clogging devices 89, which are arranged in an array on the upper end of the cleaning plate 83. The anti-clogging devices 89 and the friction holes 84 are staggered. The projection of the anti-clogging device 89 directly above it is a square. The anti-clogging device 89 can effectively clean the surface of the filter screen 7 and prevent the surface of the filter screen 7 from being blocked, thus affecting the flow of fluid.

[0030] As a further implementation of the above technical solution: a plurality of slide grooves 85, springs 86 and extrusion plates 87 are provided, and the slide grooves 85, springs 86 and extrusion plates 87 are evenly and equidistantly distributed on the outside of the cleaning plate 83. The springs 86 are located between the slide grooves 85 and the extrusion plates 87. The outside of the extrusion plates 87 is slidably connected to the inside of the slide grooves 85. The springs 86 are perpendicular to the slide grooves 85 and the extrusion plates 87. The cleaning plate 83 will be in close contact with the inner wall of the valve body 1 through the internal springs 86, which can effectively clean the inner wall of the valve body 1.

[0031] As a further implementation of the above technical solution: several brushes 88 are provided and are evenly and equidistantly distributed on one side of the extrusion plate 87. The brushes 88 are S-shaped and are in close contact with the inner wall of the valve body 1. The brushes 88 provided on the outside of the cleaning plate 83 will be in close contact with the inner wall of the valve body 1 through the internal spring 86, so as to continuously clean the inner wall of the valve body 1.

[0032] As a further implementation of the above technical solution: by setting anti-clogging columns 892, there are several anti-clogging columns 892, which are evenly and equidistantly distributed on the upper end of the shock-absorbing plate 891. The vertical cross section of the upper end of the anti-clogging column 892 is set as a triangle, and the anti-clogging column 892 is perpendicular to the upper end of the shock-absorbing plate 891. The anti-clogging columns 892 can effectively clean the surface of the filter screen 7.

[0033] Working Process: During operation, the compact valve body 1 with its heat dissipation structure operates at room temperature when the equipment is first started. The thermal element 3 contracts, allowing fluid to continuously expel initial air through the water flow channel 9, enabling rapid start-up. When condensate enters the valve body 1, the float 6 rises with the condensate level. At this time, the condensate is discharged from the valve seat 4 through the water flow channel 9. When hot condensate and steam enter the valve body 1, the thermal element 3 expands due to heat, closing the valve. The float 6 floats with the condensate level, adjusting the opening of the valve seat 4 to discharge condensate. When no condensate enters the valve body 1, the float 6 descends with the level, closing the valve seat 4. Since the valve seat 4 is located below the condensate level, a water seal is formed, preventing steam leakage. When the water level rises again... When valve seat 4 opens, condensate is discharged, forming a circulation. As float 6 rises and falls with the condensate level, the cleaning device 8 will also rise and fall with the condensate level. The brush 88, located on the outside of cleaning plate 83, will be tightly attached to the inner wall of valve body 1 via internal spring 86, effectively cleaning the inner wall of valve body 1 and preventing dirt from adhering to the surface of valve body 1. When cleaning device 8 rises, it will enter the inside of filter screen 7, and the outside of float 6 will block the lower end of filter screen 7. The anti-clogging column 892 can effectively clean the surface of filter screen 7, preventing the surface of filter screen 7 from being blocked and affecting fluid flow. The cleaned impurities and dirt will be discharged out through drain hole 5, effectively ensuring the normal use of valve body 1.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
