Description

Technical Field

[0001] This utility model relates to the field of condensate drain technology, and in particular to a heat tracing condensate drain regulator. Background Technology

[0002] In many industrial production processes and certain application scenarios, the medium transported in pipelines needs to be kept at a certain temperature to prevent the medium from solidifying, increasing in viscosity, or undergoing other physicochemical changes that are detrimental to transportation and use. Heat tracing technology is a widely used method to meet this requirement.

[0003] Traditional heat tracing systems typically use steam or electric heat tracing. In steam heat tracing systems, steam condenses into water after releasing heat. If this condensate is not drained in a timely and effective manner, it will accumulate in the pipes, causing water hammer. This not only impacts and damages the pipes, affecting their service life, but may also reduce heat transfer efficiency, thus affecting the heat tracing effect.

[0004] Currently, mechanical steam traps, thermostatic steam traps, and thermodynamic steam traps are commonly used for steam trapping and drainage. However, current steam traps all rely on mechanical principles, which have low precision. This results in poor temperature control accuracy, inability to predict water volume in advance, and delayed closure of the steam trap after drainage. As a result, steam is released under pressure, leading to steam waste over time. Furthermore, routine inspections in winter mainly rely on touching the pipes to check for overheating and determine if the steam traps are malfunctioning. This inspection efficiency is low, especially in winter. If inspections are missed and not addressed in time, it can cause instrument measurement failures, leading to plant shutdowns or production fluctuations. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a heat tracing condensate regulator, which solves the technical problems of existing technologies relying on mechanical principles, which suffer from poor temperature control accuracy and varying degrees of water vapor carryover, resulting in energy waste. This regulator achieves the goal of precise control of the heat tracing system to prevent vapor buildup and drain water, thus avoiding energy waste.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a heat tracing and drainage regulator, comprising a connecting pipe installed in the regulator body, wherein a heat tracing pipe and a drain pipe are respectively installed at the left and right ends of the connecting pipe, and multiple temperature sensors are installed on the heat tracing pipe and the drain pipe; a steam venting mechanism for blocking steam and draining water is provided in the connecting pipe, and a control mechanism for controlling the operation of the steam venting mechanism according to the temperature is provided on the regulator body.

[0007] A further improvement is that the exhaust mechanism includes a micro motor installed in a mounting cavity within the regulator body, and the output end of the micro motor is connected to a reduction gear. A switching gear is meshed on the reduction gear, and a ball valve extending into the connecting pipe is installed on the switching gear.

[0008] A further improvement is that the control mechanism includes a display screen mounted on the regulator body, and control buttons are mounted on the regulator body below the display screen, and a battery for powering the regulator body is installed inside the regulator body.

[0009] A further improvement is that the temperature sensor is a PT100 platinum resistance thermometer, and multiple temperature sensors are electrically connected to the control mechanism via signal cables.

[0010] A further improvement is that the micro motor is a DC motor with a working voltage of 3~5V, and it is electrically connected to the temperature sensor and the control mechanism, and the battery is a 3.7V lithium battery.

[0011] A further improvement is that internal threads are provided at both ends of the inner wall of the connecting pipe, and external threads that are compatible with the internal threads on the connecting pipe are provided at the connection ports of the heat tracing pipe and the drain pipe.

[0012] By employing the above technical solution, this utility model provides a heat tracing hydrophobic regulator, which has at least the following beneficial effects:

[0013] 1. This utility model monitors the temperature of the heat tracing pipe in real time through a temperature sensor. When the temperature approaches the preset temperature, different electrical signals are sent to drive the steam exhaust mechanism to open and drain steam according to the difference between the preset temperature and the actual temperature and the magnitude of the change. This accurately controls the temperature and avoids the phenomenon of water carrying steam, thus avoiding energy waste.

[0014] 2. This utility model transmits the temperature detected by the temperature sensor on the heat tracing pipe to the display screen in real time. The inspection personnel only need to observe the temperature displayed on the screen to know the pipe temperature, which improves the inspection efficiency. In addition, with the control button, the corresponding heat tracing temperature can be set for different medium temperature requirements, which improves the applicability of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Current technologies all rely on mechanical principles, which suffer from low precision, poor temperature control, and varying degrees of water vapor carryover, leading to energy waste. This embodiment provides a heat tracing and condensate drain regulator. Please refer to [reference needed]. Figures 1-3 This embodiment provides a heat tracing drain regulator that can precisely control the steam blocking and drainage of the heat tracing system, avoiding energy waste. The heat tracing drain regulator includes a connecting pipe 2 installed inside the regulator body 1. A heat tracing pipe 3 and a drain pipe 4 are respectively installed at the left and right ends of the connecting pipe 2, and multiple temperature sensors 5 are installed on the heat tracing pipe 3 and the drain pipe 4. A steam venting mechanism 6 for steam blocking and drainage is provided inside the connecting pipe 2, and a control mechanism 7 is provided on the regulator body 1 to control the operation of the steam venting mechanism 6 according to the temperature. The temperature of the heat tracing pipe 3 is monitored in real time by the temperature sensors 5 installed on the heat tracing pipe 3. The resistance value of the temperature sensor is calculated based on the ratio of the voltage value obtained by the voltage division between the temperature sensor 5 and the fixed resistor to the total voltage, and then calculated according to the formula: The calculated temperature is used to control the steam exhaust mechanism 6 to open and drain steam when the temperature approaches the preset temperature of the control mechanism 7. This is done based on the difference between the preset temperature and the actual temperature and the magnitude of the difference. This ensures precise temperature control and avoids water carrying steam, thus preventing energy waste.

[0025] Since existing technologies rely on mechanical principles and lack precision, they suffer from poor temperature control accuracy, leading to steam carryover and energy waste. This device also includes a steam exhaust mechanism 6, which comprises a micro motor 61 installed in a cavity within the regulator body 1. The output of the micro motor 61 is connected to a reduction gear 62, which meshes with a switching gear 63. A ball valve 64 extending into the connecting pipe 2 is mounted on the switching gear 63. When the temperature detected by the temperature sensor 5 on the heat tracing pipe 3 reaches a preset value, the micro motor 61 is activated, driving the reduction gear 62 to rotate, which in turn drives the meshing switching gear 63 to rotate, thereby rotating the ball valve 64. The opening range of the ball valve 64 is controlled according to different temperatures, achieving precise steam blocking and drainage, thus avoiding energy waste.

[0026] Since traditional inspection methods mainly rely on touching the pipes by hand to check for overheating and determine whether the steam trap is faulty, the inspection efficiency is low. Therefore, the device is also equipped with a control mechanism 7. The control mechanism 7 includes a display screen 71 installed on the regulator body 1, and a control button 72 is installed on the regulator body 1 below the display screen 71. A battery 73 is installed inside the regulator body 1 to power it.

[0027] Temperature sensor 5 is a PT100 platinum resistance thermometer, and multiple temperature sensors 5 are electrically connected to the control mechanism 7 via signal cables. The temperature detected by the temperature sensor 5 on the heat tracing pipe 3 is transmitted to the display screen 71 in real time. The inspection personnel only need to observe the temperature displayed on the display screen 71 to know the pipe temperature, which improves the inspection efficiency. In addition, with the control button 72, the corresponding heat tracing temperature can be set according to different medium temperature requirements, which improves the applicability of the device.

[0028] The micro motor 61 is a DC motor with a working voltage of 3~5V, and it is electrically connected to the temperature sensor 5 and the control mechanism 7. According to the built-in program, the micro motor 61 automatically controls the opening of the ball valve 64, thereby achieving automatic and precise exhaust and making it more intelligent. The battery 73 is a 3.7V lithium battery.

[0029] Both ends of the inner wall of the connecting pipe 2 are provided with internal threads, and the connection ports of the heat tracing pipe 3 and the drain pipe 4 are provided with external threads that are compatible with the internal threads on the connecting pipe 2. The connection can be quickly made by screwing the heat tracing pipe 3 and the drain pipe 4 into the connecting pipe 2, which is more convenient and labor-saving.
