Description

Technical Field

[0001] The utility model relates to the field of ice water machine maintenance, in particular to a water channel sealing device which is convenient for ice water machine maintenance. Background Art

[0002] Leakage plugging under pressure is to use appropriate seals to completely cut off the channel for medium leakage; or to block or isolate the leakage medium channel; or to increase the flow resistance of the fluid in the leakage medium channel to form a closed space to prevent the fluid from leaking. Among the many types of failures of chillers, a large part is related to pipeline leakage. When repairing failures related to pipeline leakage, a device is needed to quickly seal the leakage point.

[0003] At present, a Chinese patent with authorization announcement number CN220749449U discloses a three-way universal pressure plugging clamp, which relates to the technical field of three-way plugging, including a first plugging clamp sleeve and a second plugging clamp sleeve, the first plugging clamp sleeve and the second plugging clamp sleeve are fixedly connected with a first connecting plate on the top, and the first plugging clamp sleeve and the second plugging clamp sleeve are fixedly connected with a second connecting plate on the inner side, and a plurality of first bolt plugging holes are provided on the first connecting plate and the second connecting plate. The pressure plugging clamp is limited in position on the three-way pipe by the first plugging clamp sleeve and the second plugging clamp sleeve, and the first connecting plate and the second connecting plate are merged at the same time as the first plugging clamp sleeve and the second plugging clamp sleeve are merged, and the fastening bolts are plugged into the first bolt plugging holes, so that the first plugging clamp sleeve and the second plugging clamp sleeve are fixed on the three-way pipe, ensuring a simple and compact structure, facilitating the subsequent convenient replacement of the sealing gasket, and improving the plugging effect.

[0004] The above-mentioned prior art solution has the following defects: the clamp is mainly used for temporary plugging of damaged pipelines in the chemical industry, no water valve is provided on the three-way pipe, and there is no corresponding sensor to detect whether the blocked pipeline is still leaking, which has certain limitations when used in the field of ice machine maintenance. Utility Model Content

[0005] The utility model aims to provide a water channel sealing device which is convenient for ice machine maintenance, so as to solve the problems existing in the above-mentioned prior art.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A water channel sealing device for facilitating the maintenance of a water chiller comprises an internally threaded sleeve and a display device, wherein the internally threaded sleeve is assembled from an upper sleeve and a lower sleeve, the lower sleeve is provided with a first through hole and a second through hole, a liquid level sensor is provided at the top of the first through hole, a power cord sleeve is coaxially provided in the first through hole, a wire is wrapped in the power cord sleeve, the liquid level sensor is electrically connected to the display device via the wire, a water outlet pipe is coaxially provided in the second through hole, a water valve is provided on the water outlet pipe, sealing blocks are symmetrically provided at the left and right ends of the internally threaded sleeve, and threads are provided on the surfaces of the sealing blocks contacting the internally threaded sleeve.

[0008] By adopting the above technical scheme, the sealing device can be quickly clamped on the leakage point of the ice machine pipeline. This sealing device is mainly composed of an internal threaded sleeve and two left and right sealing blocks. After the two sealing blocks are sleeved on the pipeline, the upper sleeve and the lower sleeve are sleeved on the sealing blocks. After fixing the internal threaded sleeve with a clamp, the internal threaded sleeve can be rotated to continuously move and rotate the left and right sealing blocks toward the middle. At this time, a closed chamber is formed between the sealing blocks and the internal threaded sleeve. A water outlet pipe and a liquid level sensor are also provided on the lower sleeve. The water outlet pipe is controlled by a water valve to control whether it is conductive or not, and the liquid level sensor can be used to determine whether there is still leakage in the pipeline. In addition to temporary blocking, it can also provide strong assistance for subsequent maintenance.

[0009] In a further embodiment, the blocking block is rotatably disposed on the internal threaded sleeve, and a gasket is sleeved on the top end of the blocking block.

[0010] By adopting the above technical solution, the rubber gasket can further increase the sealing between the sealing block and the internal threaded sleeve. The rubber gasket is also divided into two halves and fixedly arranged on the top of the left sealing block and the right sealing block. The surface of the sealing block is not completely covered with threads, only the front section is provided with threads.

[0011] In a further embodiment, the blocking block comprises an upper blocking block and a lower blocking block, and a fixing buckle is provided at the connection between the bottom ends of the upper blocking block and the lower blocking block.

[0012] By adopting the above technical solution, when the sealing block is sleeved on the pipe, the bottom end can be initially fixed by a fixing buckle, and after the top end of the sealing block is pushed into the internal threaded sleeve, both the top and the bottom ends can be fixed, and then the sealing block can be completely fixed in the internal threaded sleeve by rotating the internal threaded sleeve.

[0013] In a further embodiment, a clamp body is disposed on the internally threaded sleeve, and the clamp body includes an upper clamp and a lower clamp, and the upper clamp is bolted to the lower clamp.

[0014] By adopting the above technical solution, the clamp is convenient and quick. When pipeline leakage occurs, the internal threaded sleeve can be quickly fixed to facilitate subsequent maintenance.

[0015] In a further embodiment, the display device includes a housing, a knob and a display screen. A receiving groove is provided on one side of the housing, a display screen is embedded in the receiving groove, and a knob is fixedly connected to the bottom end of the display screen.

[0016] By adopting the above technical solution, the liquid accumulation inside the sealing device can be checked through the display device to determine whether the pipeline leakage is still occurring. At the same time, the circulating liquid inside the closed cavity can be discharged through the water valve first to prevent the leakage from flowing into the interior of the chiller when the internal threaded sleeve is disassembled, thereby damaging other components.

[0017] In a further embodiment, the internally threaded sleeve and the blocking block are both made of stainless steel.

[0018] By adopting the above technical solution, the corrosion resistance, wear resistance and strength of stainless steel 304 are sufficiently high, and the service life is long.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. Through the setting of the internal thread sleeve and the sealing block, a sealed internal cavity can be quickly manufactured to prevent the continuous leakage of the ice machine pipeline;

[0021] 2. Through the setting of the liquid level sensor and the water valve, the outflow of the liquid inside the sealed cavity formed between the internal threaded sleeve and the sealing block can be freely controlled, and at the same time, the leakage of the pipeline can be monitored;

[0022] 3. Through the setting of the display device, the information of the liquid level sensor can be updated on the display device in real time, which makes it easier for maintenance personnel to confirm the leakage of the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example:

[0030] like Figure 1-3As shown, a water channel sealing device for facilitating the maintenance of a chiller comprises an internal threaded sleeve 1 and a display device 2, wherein the internal threaded sleeve 1 is assembled from an upper sleeve 11 and a lower sleeve 12, a clamp body 17 is arranged on the internal threaded sleeve 1, the clamp body 17 comprises an upper clamp 171 and a lower clamp 172, the upper clamp 171 is bolted to the lower clamp 172, a first through hole and a second through hole are arranged on the lower sleeve 12, a liquid level sensor 13 is arranged at the top of the first through hole, a power cord sleeve 14 is coaxially arranged in the first through hole, a wire is wrapped in the power cord sleeve 14, the liquid level sensor 13 is electrically connected to the display device 2 through the wire, a water outlet pipe 15 is coaxially arranged in the second through hole, and an outlet pipe 15 is arranged at the top of the first through hole. A water valve 16 is provided on the water pipe 15. After the sealing block 3 is sleeved up and down on both ends of the leaking pipe, the buckle is put on, and the upper sleeve 11 and the lower sleeve 12 are quickly sleeved on the leaking pipe and fixed by a clamp. This fixing method is convenient and fast, and is very suitable for blocking leaking pipes. After the fixing is completed, the internal threaded sleeve 1 can be rotated a few times to cooperate with the thread on the sealing block 3 to create a closed chamber to prevent the circulating fluid inside the ice machine from continuing to leak. A liquid level sensor 13 is provided in the internal threaded sleeve 1 to detect the internal leakage in real time. When the accumulated liquid in the cavity needs to be discharged, the water valve 16 can be twisted to discharge the circulating fluid from the water outlet pipe 15.

[0031] like Figure 1-2 As shown, the left and right ends of the internal threaded sleeve 1 are symmetrically provided with sealing blocks 3, the surfaces of the sealing blocks 3 contacting the internal threaded sleeve 1 are provided with threads, the sealing blocks 3 are rotatably provided on the internal threaded sleeve 1, the top of the sealing blocks 3 is sleeved with a gasket 33, the sealing blocks 3 include a left sealing block 31 and a right sealing block 32, the connection between the bottom ends of the left sealing block 31 and the right sealing block 32 is provided with a fixing buckle 34, the display device 2 includes a shell 21, a knob 22 and a display screen 23, a side of the shell 21 is provided with a receiving groove, the display screen 23 is embedded in the receiving groove, and the bottom end of the display screen 23 is fixedly connected to the knob 22 The internal threaded sleeve 1 and the sealing block 3 are both made of stainless steel. The threads on the sealing block 3 can cooperate with the internal threads of the internal threaded sleeve 1 to increase the sealing performance of the device. The gasket 33 is made of rubber and can also increase the airtightness of the cavity. The display device 2 can cooperate with the liquid level sensor 13 to display the liquid level inside the cavity at any time, so as to determine whether the pipeline is still leaking. The knob 22 can adjust the displayed value to accurately determine whether there is still leakage inside the sealing device. The sealing block 3 and the internal threaded sleeve 1 made of stainless steel have excellent corrosion resistance and are very suitable for blocking leakage of circulating fluid in ice machines.

[0032] Specific implementation process: First, find the leaking pipe, then set the two sealing blocks on the pipe symmetrically with the leak point as the midpoint. After the upper and lower sealing blocks are pressed on the pipe, put on the fixing buckles, and the sealing blocks can be initially fixed. Then, the upper sleeve and the lower sleeve are respectively put on the pipe at the leaking point, and then the internal threaded sleeve is clamped with a clamp. Then, the left and right sealing blocks are moved toward the sleeve respectively, so that the sealing blocks are close to the thread at one end of the internal threaded sleeve and the thread connection of the sleeve. Then, the internal threaded sleeve can be rotated to continuously tighten the two sealing blocks to form a closed cavity. When the circulating fluid in the pipeline continues to leak, it will continuously fill this cavity. When After the cavity is filled, the circulating liquid in the pipeline can continue to run, but impurities will increase. When the chiller and water-using devices are all stopped, the circulating liquid in the chiller can be gradually discharged through the drainage pipe and water valve. The liquid level sensor can accurately measure whether there is circulating liquid in the sealing device. After draining, start repairing the chiller and fill the leaking pipe. After the filling and repair are completed, the sealing device can be installed again, and the chiller can be tested and the display device can be observed. If the data on the display is normal and the liquid level sensor does not detect leakage, the device is operating normally. Otherwise, the leakage problem has not been solved and further disassembly and maintenance are required.
