[0002] Steam traps are widely used in heating equipment that can generate steam. Their main function is to separate and discharge condensed water from the heating equipment while retaining steam to the maximum extent to improve the efficiency and reliability of the system. However, as the steam traps age, they may leak, meaning that steam may be discharged through the steam traps together with condensed water, resulting in a large amount of high-temperature steam leakage and energy waste. Utility Model Content

[0003] The main purpose of the utility model is to provide a steam trap detection device and a heating device, so as to facilitate the detection of whether the steam trap is leaking.

[0004] To achieve the above-mentioned purpose, the utility model proposes a steam trap detection device, comprising a gas-liquid separation tank, an exhaust pipe, a drain pipe and a temperature sensor; the gas-liquid separation tank is provided with a liquid inlet, an exhaust port and a drain port, the liquid inlet is used to communicate with the outlet end of the steam trap; the exhaust pipe is connected to the exhaust port; the drain pipe is connected to the drain port; at least one of the exhaust pipe and the drain pipe is provided with the temperature sensor.

[0005] The technical solution of the utility model is to provide a liquid inlet on the gas-liquid separation tank to communicate with the outlet end of the steam trap, so that the gas-liquid mixture flowing out of the outlet end of the steam trap flows into the gas-liquid separation tank for gas-liquid separation, thereby separating the gas-liquid mixture. By connecting the exhaust pipe to the exhaust port of the gas-liquid separation tank, connecting the drain pipe to the drain port of the gas-liquid separation tank, and providing a temperature sensor on at least one of the exhaust pipe and the drain pipe, it is convenient to perform temperature detection on the separated liquid and / or gas separately, so that when the temperature is detected to be within the normal temperature range, it is judged that the steam trap is in a non-leaking state, and when the temperature is detected to be too high, it is judged that the steam trap is leaking. By separating the gas and liquid and then performing temperature detection on the gas and / or liquid separately, the accuracy of the detection is improved, and the risk of inaccurate detection caused by the inability to determine whether the steam trap is leaking or the flow is too large when the gas and liquid are mixed in large quantities is reduced.

[0006] In one embodiment, a power pump is provided on the liquid discharge pipe.

[0007] Such an arrangement can improve the stability and efficiency of the liquid flow in the drain pipe, thereby facilitating the discharge of the liquid in the drain pipe.

[0008] In one embodiment, the temperature sensor includes a first temperature sensor, which is disposed on the drain pipe and located at the rear end of the power pump.

[0009] Such a configuration can, on the one hand, ensure that the first temperature sensor can detect the temperature of the liquid in the discharge pipe; on the other hand, it can reduce the risk of temporary temperature increase caused by large flow rate or incomplete gas-liquid separation. Therefore, arranging the first temperature sensor at the rear end of the power pump can also obtain more accurate measurement results.

[0010] In one embodiment, the power pump includes a liquid flow channel and a gas flow channel isolated from each other, the liquid flow channel is connected to the liquid discharge pipe, and the gas flow channel has an outlet, and the outlet is connected to the exhaust pipe.

[0011] With such arrangement, the gas or steam entering the gas flow channel can be discharged into the external environment through the exhaust pipe, thereby reducing the need to separately set up a pipeline connected to the external environment, thereby reducing the number of pipelines connected to the external environment, and simplifying the structure of the steam trap detection device.

[0012] In one embodiment, the end of the liquid discharge pipe is also connected to a liquid recovery tank.

[0013] With such an arrangement, the condensed water can be recovered and reused, thereby improving energy utilization.

[0014] In one embodiment, the gas-liquid separation tank is also provided with a sewage outlet.

[0015] Such an arrangement makes it easy for the user to clean and repair the gas-liquid separation tank without disassembling the drain pipe.

[0016] In one embodiment, a sealing member is installed at the sewage outlet.

[0017] With such an arrangement, the drain outlet can be in a closed state when the gas-liquid separation tank is in a state of performing gas-liquid separation on the gas-liquid mixture, thereby reducing the risk of liquid being discharged from the drain outlet.

[0018] In one embodiment, the steam trap detection device includes a mounting bracket, and the gas-liquid separation tank is mounted on the mounting bracket.

[0019] Such an arrangement makes the installation of the gas-liquid separation tank more stable.

[0020] In one embodiment, the mounting bracket includes a mounting seat and a support frame, one end of the support frame is connected to the mounting seat, and the other end of the support frame supports the gas-liquid separation tank.

[0021] Such an arrangement, on the one hand, enables the mounting base to have a stable supporting effect on the support frame, thereby improving the supporting stability of the gas-liquid separation tank; on the other hand, the support frame supports the gas-liquid separation tank, which makes it convenient to provide sufficient space under the gas-liquid separation tank to connect components such as the drain pipe.

[0022] In one embodiment, the steam trap detection device further includes an overflow pipe, one end of which is disposed in the gas-liquid separation tank, and the other end of which is disposed outside the gas-liquid separation tank.

[0023] Such an arrangement reduces the risk of the liquid level in the gas-liquid separation tank being too high and thus affecting the life of the gas-liquid separation tank.

[0024] In one embodiment, the liquid inlet is provided in plurality.

[0025] Such an arrangement improves the efficiency of detecting whether multiple steam traps are leaking at the same time and saves detection costs.

[0026] In one embodiment, a plurality of the drainage ports are provided, and the plurality of drainage ports are connected to the drainage pipe.

[0027] Such an arrangement improves the efficiency of the liquid discharged from the gas-liquid separation tank.

[0028] The utility model also provides a heating device, comprising the above-mentioned steam trap detection device. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Steam traps are automatic valves widely used in heating equipment that can generate steam. Their main function is to separate and discharge condensate from the heating equipment while retaining steam to the maximum extent possible to improve the efficiency and reliability of the system. As steam traps age and approach their design life, they may leak. At this point, steam may be discharged through the steam trap along with condensate, resulting in a large amount of high-temperature steam leakage and energy waste.

[0049] In order to facilitate the detection of whether a steam trap is leaking, the utility model provides a steam trap detection device.

[0050] Please refer to Figures 1 to 3 In one embodiment of the utility model, the steam trap detection device includes a gas-liquid separation tank 100, an exhaust pipe 200, a drain pipe 300 and a temperature sensor 400; the gas-liquid separation tank 100 is provided with a liquid inlet 110, an exhaust port and a drain port, the liquid inlet 110 is used to communicate with the outlet end of the steam trap; the exhaust pipe 200 is connected to the exhaust port; the drain pipe 300 is connected to the drain port; at least one of the exhaust pipe 200 and the drain pipe 300 is provided with a temperature sensor 400.

[0051] The gas-liquid separation tank 100 is a tank device for separating steam and condensed water. The gas-liquid separation tank 100 has a liquid inlet 110, and the liquid inlet 110 can be used for the condensed water flowing out of the water outlet of the steam trap to pass through. Then the condensed water flowing out of the water outlet of the steam trap is in the gas-liquid separation tank 100. It can be understood that under normal conditions, that is, when the steam trap is not leaking, the temperature of the condensed water flowing out of the steam trap is usually between 80°C and 97°C, so the condensed water flowing out of the steam trap carries a small amount of steam. If the steam trap leaks, the condensed water flowing out of the outlet of the steam trap carries a large amount of steam. Therefore, by setting the gas-liquid separation tank 100, the gas-liquid mixture flowing out of the steam trap can be separated into gas and liquid. The gas-liquid separation tank 100 also has an exhaust port and a liquid discharge port. Since the steam temperature is relatively high, the steam generally moves upward, and thus the exhaust port may be disposed at the top of the gas-liquid separation tank 100 . Liquid is generally heavier, and in order to facilitate automatic discharge of the liquid, the liquid discharge port may be disposed at the bottom of the gas-liquid separation tank 100 .

[0052] The exhaust pipe 200 refers to a pipe for discharging the gas in the gas-liquid separation tank 100. The cross-sectional shape of the exhaust pipe 200 may be circular, rectangular or other shapes. Both ends of the exhaust pipe 200 are provided with openings, one end of the exhaust pipe 200 is connected to the exhaust port, and the other end is used to connect to the external environment. When the exhaust pipe 200 is connected to the exhaust port, the exhaust pipe 200 can be connected to the exhaust port of the gas-liquid separation tank 100 through a flange assembly; or the exhaust pipe 200 and the exhaust port of the gas-liquid separation tank 100 are set as an integrated structure by welding, bonding or integral molding; or one end of the exhaust pipe 200 is passed through the exhaust port and extends into the gas-liquid separation tank 100, and the other end is arranged outside the gas-liquid separation tank 100 and communicates with the external environment. The exhaust pipe 200 can be a straight pipe or a curved pipe.

[0053] The drain pipe 300 refers to a pipe for discharging the liquid in the gas-liquid separation tank 100. The cross-sectional shape of the drain pipe 300 may be circular, rectangular or other shapes. One end of the drain pipe 300 is connected to the drain port, and the other end is used to connect to the external environment or to the liquid storage tank. When the drain pipe 300 is connected to the drain port, the drain pipe 300 can be connected to the drain port of the gas-liquid separation tank 100 through a flange assembly; or the drain pipe 300 and the drain port of the gas-liquid separation tank 100 are set as an integrated structure by welding, bonding or integral molding; or one end of the drain pipe 300 is passed through the drain port and extends into the gas-liquid separation tank 100, and the other end is arranged outside the gas-liquid separation tank 100 and connected to the external environment. The drain pipe 300 may be a straight pipe or a curved pipe.

[0054] The temperature sensor 400 is a sensor for measuring temperature. In terms of the measurement method, the temperature sensor 400 can be a contact sensor or a non-contact sensor. In terms of sensor materials and electronic component characteristics, the temperature sensor 400 can be a thermal resistor sensor or a thermocouple sensor. Specifically, there can be only one temperature sensor 400, and the temperature sensor 400 can be only arranged on the exhaust pipe 200, or only arranged on the drain pipe 300; or there can be at least two temperature sensors 400, wherein the two temperature sensors 400 can be respectively defined as a first temperature sensor 410 and a second temperature sensor 420, and the first temperature sensor 410 and the second temperature sensor 420 are respectively arranged on the drain pipe 300 and the exhaust pipe 200. When the steam trap is not leaking, the temperature of the condensed water discharged from the drain pipe 300 will not be too high, and the amount of steam carried in the condensed water is also small. Therefore, the temperature sensor 400 disposed on the drain pipe 300, for example, the temperature detected by the temperature sensor 400 on the drain pipe 300 will not exceed the first preset temperature threshold range, which can be set to not less than 80°C and not more than 97°C in the present application. If the steam trap leaks, the amount of steam carried in the condensed water will increase, and the temperature of the steam will also be higher. At this time, the temperature in the drain pipe 300 detected by the temperature sensor 400 on the drain pipe 300 will continue to be greater than 100°C for a certain period of time. When the steam trap is not leaking, the temperature of the steam discharged from the exhaust pipe 200 will not be too high. For example, in the present application, the temperature in the exhaust pipe 200 is only slightly higher than 100°C, such as 101°C, 102°C, 103°C. If the steam trap leaks, the amount of steam in the gas-liquid separation tank 100 will increase, thereby increasing the gas pressure in the gas-liquid separation tank 100, and further greatly increasing the temperature of the steam. If the temperature detected by the temperature sensor 400 on the exhaust pipe 200 exceeds the second preset temperature threshold, for example, the second preset temperature threshold can be set to 105°C. If the temperature sensor 400 is provided on both the exhaust pipe 200 and the drain pipe 300, it can be more accurately determined whether the steam trap at the front end of the steam trap detection device is leaking by combining the steam temperature in the exhaust pipe 200 and the liquid temperature in the drain pipe 300.

[0055] The technical solution of the utility model is to provide a liquid inlet 110 for communicating with the outlet end of the steam trap on the gas-liquid separation tank 100, so that the gas-liquid mixture flowing out of the outlet end of the steam trap flows into the gas-liquid separation tank 100 for gas-liquid separation, thereby separating the gas-liquid mixture. By connecting the exhaust pipe 200 to the exhaust port of the gas-liquid separation tank 100, connecting the drain pipe 300 to the drain port of the gas-liquid separation tank 100, and providing at least one of the exhaust pipe 200 and the drain pipe 300 with a temperature sensor 400, it is convenient to perform temperature detection on the separated liquid and / or gas separately, so that when the temperature is detected to be within the normal temperature range, it is judged that the steam trap is in a non-leaking state, and when the temperature is detected to be too high, it is judged that the steam trap is leaking. By separating the gas and liquid and then performing temperature detection on the gas and / or liquid separately, the accuracy of the detection is improved, and the risk of inaccurate detection caused by the inability to determine whether the steam trap is leaking or the flow is too large when the gas and liquid are mixed in large quantities is reduced.

[0056] Please refer to Figures 1 to 3 In one embodiment of the present invention, a power pump 500 is provided on the discharge pipe 300 .

[0057] The power pump 500 is a power source for providing flow power for the liquid discharged from the gas-liquid separation tank 100. The power pump 500 can be a pneumatic pump or an electric pump. It should be noted that pneumatic pumps and electric pumps are well known to those skilled in the art, so they are not described in detail.

[0058] By arranging the power pump 500 on the drain pipe 300 , the stability and efficiency of the liquid flow in the drain pipe 300 can be improved, thereby facilitating the discharge of the liquid in the drain pipe 300 .

[0059] Please refer to Figure 1 and Figure 3 In one embodiment of the present invention, the temperature sensor 400 includes a first temperature sensor 410 . The first temperature sensor 410 is disposed on the drain pipe 300 and is located at the rear end of the power pump 500 .

[0060] The first temperature sensor 410 is a sensor for detecting the temperature of the liquid in the discharge pipe 300. The first temperature sensor 410 may be a contact sensor or a non-contact sensor. Alternatively, the first temperature sensor 410 may be a thermal resistor sensor or a thermocouple sensor.

[0061] The first temperature sensor 410 is located at the rear end of the power pump 500, which means that the first temperature sensor 410 is located on a pipeline connected to the end of the power pump 500 away from the gas-liquid separation tank 100. It is understandable that when the flow rate of the gas-liquid mixture flowing out of the steam trap is large or the gas-liquid separation tank 100 does not separate the steam and liquid so thoroughly, the pressure in the gas-liquid separation tank 100 will be large, and the temporary high pressure may cause the discharge port of the gas-liquid separation tank 100 to temporarily increase in temperature. Since the front end of the power pump 500 is close to the discharge port of the gas-liquid separation tank 100, the temperature range of the liquid at the front end of the power pump 500 fluctuates greatly, and the risk of inaccurate measurement is easily caused when measuring the temperature here.

[0062] By arranging the first temperature sensor 410 on the discharge pipe 300 and at the rear end of the power pump 500, on the one hand, it can be ensured that the first temperature sensor 410 can detect the temperature of the liquid in the discharge pipe 300; on the other hand, it can reduce the risk of temporary temperature increase caused by a large flow rate or incomplete gas-liquid separation. Therefore, arranging the first temperature sensor 410 at the rear end of the power pump 500 can also obtain more accurate measurement results.

[0063] Please refer to Figures 1 to 3 In one embodiment of the present invention, the power pump 500 includes a liquid flow channel and a gas flow channel that are isolated from each other. The liquid flow channel is connected to the discharge pipe 300 , and the gas flow channel has an outlet that is connected to the exhaust pipe 200 .

[0064] The power pump 500 in this embodiment is a pneumatic pump, which includes a liquid flow channel and a gas flow channel isolated from each other, wherein the liquid flow channel is used to communicate with the drain pipe 300, thereby providing power for the liquid in the drain pipe 300. One end of the liquid flow channel can be connected to the drain port, and the other end is connected to the inlet of the drain port; or the pneumatic pump is arranged in the middle section of the drain pipe 300. The gas flow channel of the pneumatic pump is responsible for conveying compressed air or steam to provide power for the pump. Specifically, the gas flow channel has an inlet and an outlet, and the inlet of the gas flow channel can be connected to the boiler room, so that the steam in the boiler room can be input into the gas flow channel to provide power for the power pump 500.

[0065] By isolating the liquid flow channel and the gas flow channel of the power pump 500 from each other, the gas providing power will not interfere with the fluid passing through the power pump 500. By connecting the liquid flow channel with the drain pipe 300, it is convenient for the liquid in the power pump 500 to flow to the drain pipe 300 and then be discharged through the drain pipe 300. By connecting the outlet of the gas flow channel to the exhaust pipe 200, the gas or steam entering the gas flow channel can be discharged to the external environment through the exhaust pipe 200, reducing the need to set up a separate pipeline connected to the external environment, thereby reducing the number of pipelines connected to the external environment, and simplifying the structure of the steam trap detection device.

[0066] like Figure 4 As shown, in one embodiment of the present invention, the end of the liquid discharge pipe 300 is also connected to a liquid recovery tank 600 .

[0067] The end of the drain pipe 300 refers to the end of the drain pipe 300 away from the gas-liquid separation tank 100 .

[0068] The liquid recovery box 600 refers to a box body used to recover the condensed water discharged from the drain pipe 300. The box body can be a rectangular parallelepiped, a cube or a cylinder, etc. The box body has a water inlet, and the water inlet can be arranged on the side wall or the top wall of the box body. In addition, the recovery box 600 can be a closed one-piece box body, or it can be an open box body. Alternatively, the recovery box 600 can include a box body with an opening and a movable cover arranged at the opening, and the movable cover can open or close the opening of the box body, so as to facilitate pouring out the condensed water in the box body when the opening is opened.

[0069] Since the end of the drain pipe 300 is connected to the liquid recovery tank 600, the condensed water can be recovered and reused, thereby improving energy utilization.

[0070] Please refer to Figures 1 to 4 In one embodiment of the present invention, the gas-liquid separation tank 100 is further provided with a sewage outlet 120 .

[0071] The drain outlet 120 refers to an opening for discharging the substances in the gas-liquid separation tank 100 when the gas-liquid separation tank 100 needs to be cleaned or repaired. It should be noted that when the gas-liquid separation tank 100 is repaired, the drain outlet or the power pump 500 on the drain pipe 300 can be closed, and then the drain outlet 120 can be opened. The drain outlet 120 can be circular, rectangular or other shapes. The shape of the drain outlet 120 can be the same as the shape of the drain port, or it can be different from the shape of the drain port. Based on the fact that the drain outlet 120 has the same shape as the drain port, further, the size of the drain outlet 120 can be the same as the size of the drain port, or it can be different from the size of the drain port.

[0072] The drain port 120 may be provided at the bottom wall of the gas-liquid separation tank 100 or at the side wall of the gas-liquid separation tank 100; of course, under the premise of draining with the assistance of other power devices, the drain port 120 may also be provided at the top of the gas-liquid separation tank 100. It is understood that when the gas-liquid separation tank 100 is in a normal working state, the drain port 120 may be in a blocked state, thereby reducing the risk of liquid flowing away from the drain port 120. The drain port 120 may be blocked by a sealing member 700, or a switch valve may be provided at the drain port 120 to control the drain port 120 to be in an open or blocked state.

[0073] By further providing a drain port 120 on the gas-liquid separation tank 100 , it is convenient for the user to clean and repair the gas-liquid separation tank 100 without disassembling the drain pipe 300 .

[0074] Please refer to Figures 1 to 4 In one embodiment of the present invention, a sealing member 700 is installed at the sewage outlet 120 .

[0075] The sealing member 700 refers to a sealing component used to block the sewage outlet 120 to prevent the liquid in the gas-liquid separation tank 100 from flowing out of the sewage outlet 120. The sealing member 700 may be a columnar plug or a T-shaped plug body, etc., in which case the sealing member 700 may be detachably mounted on the sewage outlet 120. Alternatively, the sealing member 700 may be a sealing plate or a sealing sheet movably arranged at the sewage outlet 120. Alternatively, the sealing member 700 may be a switch valve, which seals the sewage outlet 120 when the switch valve is in a closed state.

[0076] By installing a seal 700 at the drain outlet 120 , the drain outlet 120 can be blocked when the gas-liquid separation tank 100 is in a state of gas-liquid separation of the gas-liquid mixture so that the drain outlet 120 is in a closed state, thereby reducing the risk of liquid being discharged from the drain outlet 120 .

[0077] Please refer to Figures 1 to 4 In one embodiment of the present utility model, the steam trap detection device includes a mounting bracket 800 , and the gas-liquid separation tank 100 is mounted on the mounting bracket 800 .

[0078] The mounting bracket 800 is a component for mounting the gas-liquid separation tank 100. The mounting bracket 800 may be a bracket structure composed of a plurality of rods, or a support structure composed of a seat, as long as the mounting bracket 800 does not interfere with the disassembly and assembly of the drain pipe 300 and the exhaust pipe 200 after the gas-liquid separation tank 100 is mounted on the mounting bracket 800.

[0079] By installing the gas-liquid separation tank 100 on the installation bracket 800 , the installation of the gas-liquid separation tank 100 is made more stable.

[0080] Please refer to Figures 1 to 4 In one embodiment of the present invention, the mounting bracket 800 includes a mounting seat 810 and a support frame 820 , one end of the support frame 820 is connected to the mounting seat 810 , and the other end supports the gas-liquid separation tank 100 .

[0081] The mounting seat 810 refers to a base for carrying the support frame 820 and the gas-liquid separation tank 100. The mounting seat 810 may be a plate-shaped body or a block-shaped body.

[0082] The support frame 820 is a frame structure for directly supporting the gas-liquid separation tank 100. The support frame 820 can be a tripod, or the support frame 820 can include at least two rods arranged in parallel, and one end of the rod away from the mounting seat 810 is provided with a supporting portion for supporting the gas-liquid separation tank 100. When the gas-liquid separation tank 100 is cylindrical, the supporting portion can have an arc-shaped supporting surface, so as to stably support the gas-liquid separation tank 100. When the gas-liquid separation tank 100 is a rectangular parallelepiped, the supporting portion can have a U-shaped groove, and the gas-liquid separation tank 100 is stuck in the U-shaped groove. When the support frame 820 is connected to the mounting seat 810, it can be connected by screw connection, riveting, snap connection, welding or integrated molding. When the gas-liquid separation tank 100 is supported at the other end of the support frame 820, it can be clamped or threaded with the other end of the support frame 820.

[0083] By connecting one end of the support frame 820 to the mounting base 810 and supporting the gas-liquid separation tank 100 at the other end, on the one hand, the mounting base 810 has a stable supporting effect on the support frame 820, thereby improving the supporting stability of the gas-liquid separation tank 100; on the other hand, the support frame 820 supports the gas-liquid separation tank 100, which makes it convenient to provide sufficient space under the gas-liquid separation tank 100 to connect components such as the drain pipe 300.

[0084] Please refer to Figures 1 to 4 In one embodiment of the present invention, the steam trap detection device further includes an overflow pipe 900 , one end of the overflow pipe 900 is disposed in the gas-liquid separation tank 100 , and the other end of the overflow pipe 900 is disposed outside the gas-liquid separation tank 100 .

[0085] The overflow pipe 900 is a pipe for overflowing the excess liquid when there is too much liquid in the gas-liquid separation tank 100. The cross-sectional shape of the overflow pipe 900 can be circular, rectangular or other shapes. The overflow pipe 900 can be a straight pipe or a curved pipe.

[0086] By arranging one end of the overflow pipe 900 inside the gas-liquid separation tank 100 and the other end outside the gas-liquid separation tank 100, when there is too much liquid in the gas-liquid separation tank 100 and cannot be discharged in time through the drain pipe 300, the liquid will flow out of the overflow pipe 900 when it reaches the top port of the overflow pipe 900, thereby reducing the risk of the liquid level in the gas-liquid separation tank 100 being too high and affecting the life of the gas-liquid separation tank 100.

[0087] Please refer to Figures 1 to 4 In one embodiment of the present invention, a plurality of liquid inlets are provided.

[0088] Specifically, when a plurality of liquid inlets 110 are provided, a plurality of liquid inlet pipes may also be provided, and each liquid inlet pipe is connected to a liquid inlet 110 .

[0089] By providing a plurality of liquid inlets 110, a plurality of steam traps can be connected to the plurality of liquid inlets 110 respectively, so that the condensed water discharged from the plurality of steam traps can be discharged into the gas-liquid separation tank 100 at the same time, and then the temperature sensor 400 can be used to detect whether there is a risk of leakage in the plurality of steam traps at one time, thereby improving the efficiency of detecting whether the plurality of steam traps are leaking at the same time and saving the detection cost.

[0090] Please refer to Figures 1 to 4 In one embodiment of the present utility model, a plurality of drain ports are provided, and the plurality of drain ports are connected to the drain pipe 300 .

[0091] Specifically, the drain pipe 300 may include a plurality of independently arranged sub-pipes, and the plurality of sub-pipes are respectively connected to the plurality of drain ports; or the drain pipe 300 includes a main pipe and a plurality of independently arranged sub-pipes, and one end of each of the plurality of sub-pipes is connected to a drain port, and the other end is connected to the main pipe. In this case, if the drain pipe 300 is provided with a temperature sensor 400, the temperature sensor 400 may be provided in plurality, and the plurality of temperature sensors 400 are respectively provided on the plurality of sub-pipes; or the temperature sensor 400 is provided in a single temperature sensor, and the temperature sensor 400 may be provided on the main pipe, thereby reducing the number of temperature sensors 400 and saving costs.

[0092] This arrangement improves the efficiency of the liquid discharged from the gas-liquid separation tank 100.

[0093] The utility model also proposes a heating device, including a steam trap detection device. The specific structure of the steam trap detection device refers to the above-mentioned embodiment. Since the heating device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0094] The heating device includes a steam generator, the outlet end of the steam generator is connected to a steam trap, and the outlet end of the steam trap is connected to a liquid inlet 110 in the steam trap detection device.

[0095] A steam generator is a device that generates steam by consuming fuel or other energy to heat water. For example, water can be heated by consuming electrical energy or by using gas. The outlet of the steam generator is used to discharge steam. It is understood that when steam flows in the pipeline, condensed water will be generated. By connecting a steam trap to the outlet of the steam generator, the steam can be retained through the steam trap and the condensed water can be discharged.

[0096] By connecting the outlet end of the steam trap to the liquid inlet 110 of the gas-liquid separation tank 100 in the steam trap detection device, the gas-liquid mixture discharged from the steam trap enters the gas-liquid separation tank 100, and then the gas-liquid mixture discharged from the outlet end of the steam trap is detected by the above-mentioned steam trap detection device, so as to determine whether the steam trap has a leakage risk.

[0097] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present invention.
