Description

Technical Field

[0001] This utility model relates to the field of drainage equipment technology, and in particular to an electric steam trap. Background Technology

[0002] In steam heating systems, steam traps are crucial energy-saving components. Their core function is to efficiently and reliably discharge condensate automatically and prevent steam leakage, enabling the steam heating system to operate normally and avoiding energy waste caused by steam leakage.

[0003] The traditional steam traps commonly used in the market today mainly rely on built-in buoyancy elements, such as floats or buoys, to work. They use the small buoyancy difference between condensate and steam on the float (or buoy) as a driving signal. When condensate accumulates, the float rises due to buoyancy, which drives or indirectly controls the valve core to open to discharge the condensate. When steam enters, the float sinks due to reduced buoyancy, which drives the valve core to close to prevent steam from escaping.

[0004] However, because the difference in buoyancy between condensate and steam on the float is extremely small, the small driving force makes the valve's opening and closing action extremely sensitive to changes in operating conditions, which can easily cause the float to make erroneous movements. When the valve core needs to be opened, it closes, causing the steam trap to fail; when the valve core needs to be closed, it opens, causing steam leakage. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] like Figure 1 and Figure 2 As shown, this embodiment provides an electric steam trap, including a steam trap body 1, a liquid level detection element 2, a control component, and an electric valve body 3. The steam trap body 1 is provided with an inlet 11, a first drain outlet 12, and a valve chamber 13. The inlet 11 is located above the first drain outlet 12, and both the inlet 11 and the first drain outlet 12 are connected to the valve chamber 13, allowing water to enter the valve chamber 13 from the inlet 11 and exit through the first drain outlet 12. The liquid level detection element 2 is disposed on the steam trap body 1 and can detect the liquid level inside the steam trap body 1. The control component is electrically connected to the liquid level detection element 2. The electric valve body 3 is disposed on the first drain outlet 12 and is electrically connected to the control component, which can control the electric valve body 3 to open or close the first drain outlet 12.

[0032] When the liquid level detection element 2 detects that the liquid level in the valve chamber 13 has risen to a certain height, it transmits a detection signal to the control component. The control component then controls the electric valve body 3 to open the first drain port 12 to discharge the water from the valve chamber 13. When the liquid level detection element 2 detects that the liquid level in the valve chamber 13 has dropped to a certain height, it transmits a detection signal to the control component. The control component then controls the electric valve body 3 to close the first drain port 12 to prevent steam escape and energy waste. The liquid level detection element 2 can accurately detect the liquid level, and the control component can accurately control the electric valve body 3 to open or close the first drain port 12, preventing erroneous actions by the electric valve body 3. Furthermore, the electric steam trap has a simple structure and low cost.

[0033] Specifically, the steam trap body 1 is a cylindrical structure, with a cylindrical valve chamber 13 inside. The inlet 11 and the first outlet 12 are both located on the side wall of the steam trap body 1, on opposite sides, facilitating water discharge from the valve chamber 13. The inlet 11 is near the top of the steam trap body 1, and the first outlet 12 is near the bottom. The liquid level detection element 2 is located at the top of the steam trap body 1. The liquid level detection element 2 is a liquid level sensor, which can be a capacitive liquid level sensor, an ultrasonic liquid level sensor, or a radar liquid level sensor; this embodiment does not limit this. The electric valve body 3 is installed on the side wall of the first outlet 12 and partially extends into the first outlet 12. The electric valve body 3 can be fixed to the side wall of the first outlet 12 with screws. The specific structure of the electric valve body 3 is based on existing technology and will not be described in detail in this embodiment. The specific structure of the control components is also based on existing technology and will not be described in detail in this embodiment.

[0034] Optionally, the steam trap body 1 includes a steam trap tank 14 and a sealing cap 15, which facilitates the manufacturing of the steam trap body 1 and reduces the manufacturing difficulty of the steam trap body 1. The sealing cap 15 is detachably connected to the steam trap tank 14, and a valve cavity 13 is formed between the sealing cap 15 and the steam trap tank 14, which facilitates the installation and removal of the sealing cap 15 and the steam trap tank 14, facilitates the cleaning of the valve cavity 13, and facilitates the installation of the liquid level detection element 2.

[0035] Specifically, the sealing cap 15 and the condensate tank 14 can be connected by snap-fit ​​or screws. A sealing ring can also be provided between the sealing cap 15 and the condensate tank 14 to improve the sealing performance between them.

[0036] Optionally, the sealing cover 15 is provided with a mounting hole, and the detection end of the liquid level detection element 2 passes through the mounting hole and extends into the valve cavity 13 to detect the height of the liquid level in the valve cavity 13.

[0037] Specifically, the end of the liquid level detection element 2 furthest from the detection end is provided with a limiting edge, which abuts against the side of the sealing cover 15 facing away from the hydrophobic tank 14. The limiting edge can be fixed to the sealing cover 15 by snap-fit ​​or screw connection, which is not limited in this embodiment.

[0038] Furthermore, the level detection element 2 is sealed to the inner wall of the mounting hole to ensure the sealing performance of the valve cavity 13. Specifically, the diameter of the limiting edge is larger than the diameter of the mounting hole, and the limiting edge seals the mounting hole. A sealing ring can be provided between the limiting edge and the sealing cover 15 to improve the sealing performance between the level detection element 2 and the mounting hole.

[0039] Because the water contains impurities, after a period of use, the impurities will enter the first drain outlet 12 and accumulate at the electric valve body 3. Too many impurities will cause the electric valve body 3 to be unable to completely close the first drain outlet 12, resulting in steam escaping and energy waste.

[0040] Optionally, the electric steam trap also includes a filter element 4, which is disposed within the valve chamber 13 and connected to the inner wall of the valve chamber 13. By providing the filter element 4, impurities in the water can be filtered, preventing impurities from accumulating at the electric valve body 3, so that the electric valve body 3 can completely close the first drain outlet 12.

[0041] Optionally, the filter element 4 is disposed at the water inlet 11 and fits against the inner wall of the valve cavity 13, so that impurities are blocked at the water inlet 11, preventing impurities from entering the valve cavity 13, facilitating the cleaning of impurities, and improving the filtration effect of the filter element 4 on impurities.

[0042] Furthermore, the filter element 4 is detachably connected to the inner wall of the valve cavity 13, facilitating the installation and removal of the filter element 4 and making it easy to disassemble and clean it. Specifically, the filter element 4 is a ring-shaped filter screen. The filter element 4 is interference-fitted into the inner wall of the valve cavity 13 and corresponds to the water inlet 11.

[0043] Optionally, the electric steam trap also includes an alarm component, which is communicatively connected to the control component. When the electric valve body 3 malfunctions and cannot open the first drain outlet 12, and the liquid level in the valve chamber 13 is too high, the liquid level detection element 2 transmits the detected signal to the control component. The control component then controls the alarm component to issue an alarm, thereby reminding personnel to check and repair it in a timely manner. Specifically, the alarm component is an audible and visual alarm.

[0044] Optionally, the electric steam trap also includes a second drain outlet and a manual regulating valve. The second drain outlet is located at the bottom of the steam trap body 1 and communicates with the valve chamber 13. The manual regulating valve is located at the second drain outlet and can open or close the second drain outlet. When the electric valve body 3 malfunctions and cannot open the first drain outlet 12, the second drain outlet is opened through the manual regulating valve to drain the water in the valve chamber 13, thus preventing safety accidents caused by poor drainage. The specific structure of the manual regulating valve is based on existing technology and will not be described in detail in this embodiment.

[0045] Optionally, the control component is equipped with a delay module, which enables the electric valve body 3 to close the first drain port 12 after a delay, ensuring that the water in the valve chamber 13 is drained. Specifically, the delay module closes the first drain port 12 after a delay of 2-5 seconds. In this embodiment, the delay module closes the first drain port 12 after a delay of 3 seconds.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
