Description

Technical Field

[0001] This utility model relates to the field of steam trap leakage monitoring technology, specifically a steam pipeline steam trap leakage rate monitoring device. Background Technology

[0002] The important function of steam traps is to automatically remove condensate and non-condensable gases such as air from heating equipment or steam pipelines, while automatically preventing steam leakage. They can effectively block steam and drain water, ensure uniform heating of steam heating equipment, make full use of the latent heat of steam, and effectively prevent water hammer in steam pipelines. Steam trap leakage may lead to a large amount of steam waste, so it is necessary to detect steam trap leakage. To more accurately determine whether a steam trap is leaking, it is necessary to combine it with ultrasonic testing methods.

[0003] In existing ultrasonic leak detection of steam traps, maintenance personnel typically use a handheld testing instrument and a probe to inspect the steam trap. This requires personnel to physically visit the steam trap, which is inconvenient for real-time inspection or for automatically detecting multiple locations on the steam trap. Utility Model Content

[0004] The purpose of this invention is to provide a steam pipeline steam trap leakage rate monitoring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A steam trap leakage rate monitoring device includes a detector and a magnetic probe, which are electrically connected by a wire. An auxiliary mechanism is provided on the outside of the steam trap, the auxiliary mechanism including:

[0007] The flip-up assembly is located on the outside of the steam trap;

[0008] A movable component is disposed at one end of the flipping component. The movable component includes a fixed frame, a lead screw is rotatably connected inside the fixed frame, and a sliding sleeve that slides and fits against the fixed frame is screwed onto the outside of the lead screw.

[0009] A clamping assembly is disposed on the outside of the magnetic probe, and the clamping assembly includes a limiting frame fixedly installed at one end of the sliding sleeve.

[0010] Furthermore, a second motor capable of driving the lead screw to rotate is fixedly installed at one end of the fixed frame.

[0011] Furthermore, a fixing sleeve is fixedly installed on the outer surface of the magnetic attraction probe, the magnetic attraction probe slides through the limiting frame, a sliding rod is symmetrically fixedly installed on one side surface of the limiting frame, the sliding rod slides through the fixing sleeve, and a spring is movably sleeved on the outer side of the sliding rod located on one side of the fixing sleeve.

[0012] Furthermore, a No. 3 motor is fixedly installed on one side surface of the limiting frame, a lever is fixedly installed at the output end of the No. 3 motor, and a stop bar is fixedly installed on the outer surface of the fixing sleeve.

[0013] Furthermore, the flipping component includes:

[0014] Two fixed rings are movably fitted onto the outside of the steam trap;

[0015] Two limiting rings are fixedly installed on the outer surface of the fixing ring;

[0016] Two rotating rings are rotatably connected to the outside of two fixed rings.

[0017] Preferably, connecting ears are fixedly installed at both ends of the outer surface of the fixed ring and the rotating ring, and bolts are detachably connected between two adjacent connecting ears. A connecting rod is fixedly installed on the outer surface of one of the rotating rings, and one end of the connecting rod is fixedly connected to the fixed frame.

[0018] Preferably, an incomplete gear ring is fixedly installed on one end surface of each of the two rotating rings, and a No. 1 motor is fixedly installed on one side surface of one of the fixed rings. The output end of the No. 1 motor is fixedly installed with a gear that meshes and drives with the incomplete gear ring.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By placing two fixed rings on the outside of the steam trap and then placing two rotating rings on the outside of the fixed rings, and fixing them with bolts, the magnetic probe is placed on one side of the steam trap. The No. 1 motor runs, driving the gear to rotate. Under the meshing transmission of the gear and the incomplete gear ring, the rotating ring is driven to rotate, rotating the magnetic probe to the other side of the steam trap, increasing the detection surface of the magnetic probe.

[0021] 2. When motor 2 operates, adjust the position of the clamping assembly to position the magnetic probe at different locations on one side of the steam trap. When motor 3 operates, it drives the lever to rotate. At this time, the lever moves the stop bar, causing the magnetic probe to move. During testing, motor 3 stops rotating, the spring pushes the fixing sleeve to reset, and also pushes the lever to reset. Simultaneously, under the magnetic attraction of the magnetic probe, it presses against the surface of the steam trap for testing. By adjusting the height of the magnetic probe, it can test different positions on the steam trap. Through multi-point testing, the accuracy of the data after testing is improved, replacing manual handheld testing and facilitating real-time detection of steam trap leaks.

[0028] 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.

[0029] Please see Figure 1-5 In this embodiment of the present invention, a steam pipe steam trap leakage rate monitoring device includes a detector 1 and a magnetic probe 102. The detector 1 and the magnetic probe 102 are electrically connected by a wire 101. The detector 1 is an ultrasonic detector, which detects whether the steam trap is leaking by detecting changes in sound. The detector 1 is installed on the outside of the pipe connected to the steam trap to facilitate real-time detection of the steam trap. The detector 1 is connected to an external PLC controller to receive the detection results of the detector 1 and to determine whether the steam trap is leaking. An auxiliary mechanism is provided on the outside of the steam trap. The auxiliary mechanism includes a flipping component 2, which is set on the outside of the steam trap. A moving component 3 is set on one end of the flipping component 2. The moving component 3 includes a fixed frame 301. A lead screw 302 is rotatably connected inside the fixed frame 301. A sliding sleeve 304 that slides and fits against the fixed frame 301 is screwed on the outside of the lead screw 302. A clamping component 4 is set on the outside of the magnetic probe 102. The clamping component 4 includes a limiting frame 401 fixedly installed on one end of the sliding sleeve 304.

[0030] Specifically, the flipping component 2 places the magnetic probe 102 on one side of the drain valve and can control the flipping position of the magnetic probe 102. The moving component 3 adjusts the up and down position of the magnetic probe 102 to facilitate multi-point detection. The clamping component 4 fixes and limits the magnetic probe 102 so that it can contact and separate from the drain valve.

[0031] Example 1

[0032] like Figure 4 and Figure 5 As shown, in this embodiment, the flipping assembly 2 includes: two fixed rings 201 movably sleeved on the outside of the drain valve, two limiting rings 202 fixedly installed on the outer surface of the fixed rings 201, and two rotating rings 203 rotatably connected to the outside of the two fixed rings 201; connecting ears 204 are fixedly installed at both ends of the outer surfaces of the fixed rings 201 and the rotating rings 203, and bolts 205 are detachably connected between two adjacent connecting ears 204; a connecting rod 209 is fixedly installed on the outer surface of one rotating ring 203, and one end of the connecting rod 209 is fixedly connected to the fixed frame 301.

[0033] In this embodiment, two fixing rings 201 are fitted onto the outside of the steam trap, and then two adjacent connecting ears 204 are connected by bolts 205 to fix the fixing rings 201 onto the outside of the steam trap. Then, two rotating rings 203 are fitted onto the outside of the fixing rings 201 and connected and fixed by bolts 205, and the magnetic probe 102 is set on one side of the steam trap.

[0034] like Figure 3 and Figure 4 As shown, in this embodiment, a second motor 303 capable of driving the lead screw 302 to rotate is fixedly installed at one end of the fixed frame 301. The second motor 303 drives the lead screw 302 to rotate, and under the sliding limit of the sliding sleeve 304 and the fixed frame 301, the sliding sleeve 304 moves up and down. A fixed sleeve 402 is fixedly installed on the outer surface of the magnetic attraction probe 102. The magnetic attraction probe 102 slides through the limiting frame 401. A sliding rod 403 is symmetrically fixedly installed on one side surface of the limiting frame 401. The sliding rod 403 slides through the fixed sleeve 402. A spring 404 is movably sleeved on the outer side of the sliding rod 403 on one side of the fixed sleeve 402. A third motor 405 is fixedly installed on one side surface of the limiting frame 401. A lever 406 is fixedly installed at the output end of the third motor 405. A stop bar 407 is fixedly installed on the outer surface of the fixed sleeve 402.

[0035] In practice, motor 303 operates, adjusting the position of clamping assembly 4 to move the magnetic probe 102 to different positions on one side of the drain valve. Motor 405 operates, driving lever 406 to rotate. At this time, lever 406 moves stop lever 407, causing fixed sleeve 402 to move magnetic probe 102 away from the drain valve under the sliding limit of fixed sleeve 402 and slide rod 403, facilitating adjustment of the position of magnetic probe 102. During testing, motor 405 stops rotating, and spring 404... The fixed sleeve 402 is reset, which also pushes the lever 406 to reset. At the same time, under the magnetic attraction of the magnetic probe 102, it is pressed against the surface of the steam trap for detection. The magnetic probe 102 is clamped by the clamping component 4, and then the height of the magnetic probe 102 is adjusted by the moving component 3 so that the magnetic probe 102 can detect different positions of the steam trap. Through multi-point detection, the accuracy of the data after detection is improved, replacing the manual handheld detector 1 for detection, and facilitating real-time detection of air leakage in the steam trap.

[0036] Example 2

[0037] Based on Example 1, in order to overcome the problem that the magnetic probe 102 can only detect on one side of the drain valve and the other side is inconvenient to detect.

[0038] like Figure 4 and Figure 5 As shown, in this embodiment, an incomplete gear ring 206 is fixedly installed on one end surface of each of the two rotating rings 203, and a No. 1 motor 207 is fixedly installed on one side surface of a fixed ring 201. A gear 208 that meshes and drives with the incomplete gear ring 206 is fixedly installed at the output end of the No. 1 motor 207.

[0039] In practice, two incomplete gear rings 206 form a complete gear ring. Motor 207 operates, driving gear 208 to rotate. Under the meshing transmission of gear 208 and incomplete gear ring 206, the rotating ring 203 is driven to rotate, rotating the magnetic probe 102 to the other side of the drain valve, increasing the detection surface of the magnetic probe 102.

[0040] In this utility model, in order to facilitate the operator's control of the utility model, the detector 1, motor 207, motor 303 and motor 405 are all electrically connected to the PLC controller. The PLC controller is existing technology and will not be described in detail here.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
