Description

Technical Field

[0001] The utility model relates to the field of heat pump units, in particular to a signal monitoring integrated component and a heat pump unit. Background Art

[0002] At present, the pressure detectors, pressure alarms and inspection valves on the exhaust pipe and return pipe of the heat pump unit are generally welded directly to the exhaust pipe and return pipe in a decentralized manner. These pipes are often far away from the inspection port of the heat pump unit, which makes it inconvenient for the staff to read the pressure information, and it is difficult to repair when the pressure detector and pressure alarm fail. At the same time, this decentralized welding method will cause too many holes in the exhaust pipe and return pipe, which is not conducive to the overall stability of the pipeline. In addition, when replacing the problematic pressure detector and pressure alarm, it is necessary to close the inspection valves on both sides, and then remove the problematic pressure detector and pressure alarm from the pipeline. At this time, there is still refrigerant in the pipeline section where the pressure detector and pressure alarm are located. During the removal process, the refrigerant is easily ejected from the pipeline, resulting in refrigerant waste and even leakage risk. Utility Model Content

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0049] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] There are usually a large number of pipes in the heat pump unit. The staff needs to monitor the sealing of the pipes at any time to ensure the normal and safe operation of the heat pump unit, especially the exhaust pipe and return pipe of the compressor. Refrigerant flows in the pipes. Refrigerant leakage can easily cause safety accidents such as fire and explosion. The amount of refrigerant also directly affects the normal operation of the compressor. Therefore, it is necessary to install pressure detectors and pressure alarms on the exhaust pipe and return pipe to monitor the sealing of the pipes and the amount of refrigerant in the pipes at any time. The pressure detector is generally used to sense the pressure of the refrigerant fluid in the pipe, and then present the pressure value in the pipe to the staff in the form of a numerical value. The staff can judge whether the pipe is normal based on the read pressure value to monitor whether there is leakage at any time; the pressure alarm is used to send an alarm or control signal when the pressure in the pipe exceeds or falls below the set threshold to remind the staff to control the amount of refrigerant in the pipe. In the past, pressure detectors, pressure alarms, and inspection valves at both ends were directly welded to the exhaust pipe and the return pipe, and were dispersed, making it difficult to monitor centrally. The exhaust pipe and the return pipe had too many holes, which was not conducive to the overall stability of the pipeline. They were far from the inspection port of the unit, making it difficult to repair when any device failed. During maintenance, since there was still refrigerant in the pipe section where the device to be repaired was located, when the device to be repaired was removed from the pipe, the refrigerant would spray out of the pipe, causing waste of refrigerant and even the risk of leakage. In addition, when it was necessary to charge the compressor with refrigerant, the traditional pressure detector, pressure alarm, and inspection valve were set far away from the inspection port of the unit, making it inconvenient for the staff to read the data, resulting in the untimely closure of the inspection valve, the weight of the refrigerant often deviated greatly, and when the stop valve needed to be closed after charging, the pressure was too high, making it difficult to close the stop valve.

[0051] Based on this, the utility model provides a signal monitoring integrated component, in which the pressure detector, the pressure alarm and the pipeline to be detected are centrally fixed on the integrated component through a stop valve, and the integrated component is arranged near the inspection panel of the heat pump unit, so as to facilitate the monitoring of the pressure condition of the pipeline to be monitored, facilitate inspection and better prevent the leakage of refrigerant in the pipeline to be monitored.

[0052] See also Figure 1-3 The embodiment of the present application provides a signal monitoring integrated component, including an integrated component 10, a first connection port 11, a plurality of second connection ports 12 and a third connection port 13 are formed on the outer wall of the integrated component 10, a main channel 10a, a first channel 11a, a plurality of second channels 12a and a third channel 13a are formed inside the integrated component 10, the first connection port 11 is connected to the main channel 10a through the first channel 11a, a plurality of second connection ports 12 are connected to the main channel 10a through the corresponding second channels 12a, and the third connection port 13 is connected to the main channel 10a through the third channel 13a.

[0053] Furthermore, in some embodiments, the signal monitoring integrated component further includes a first stop valve 111, and the interface of the pipeline to be monitored is connected to the first connection port 11 through the first stop valve 111. Specifically, the first stop valve 111 is a multi-way stop valve, wherein one through pipe is connected to the first connection port 11, and another through pipe is connected to the interface of the pipeline to be monitored. When the switch of the first stop valve 111 is in an open state, the refrigerant in the pipeline to be monitored can flow into the integrated component 10, and when the switch of the first stop valve 111 is in a closed state, the refrigerant is blocked in the pipeline to be monitored.

[0054] Further, in some embodiments, the signal monitoring integrated component also includes a plurality of second stop valves 121 and a plurality of pressure detectors 122, and one end of the pressure detector 122 is connected to the second connection port 12 through the second stop valve 121. Specifically, the second stop valve 121 is a multi-way stop valve, one of which is connected to the second connection port 12, and another of which is connected to the pressure detector 122. When the pressure detector 122 is in working state, the pressure detector 122 passes through the channel in the second stop valve 121 and is connected to the second connection port 12; when the pressure detector 122 has a problem and needs to be repaired or replaced, the second stop valve 121 is closed, and then the pressure detector 122 is taken out from the channel of the second stop valve 121, so as to avoid the leakage of the refrigerant in the integrated component 10. It can be understood that the pressure detector 122 can be a pressure sensor, a pressure gauge or other device for pressure detection, and the number of the corresponding second connection ports 12 matches the number of the set pressure detectors 122.

[0055] Furthermore, in some embodiments, the signal monitoring integrated component further includes a third shut-off valve 131 and a pressure alarm 132, and one end of the pressure alarm 132 is connected to the third connection port 13 through the third shut-off valve 131. Specifically, the third shut-off valve 131 is a multi-way pipe shut-off valve, one of which is connected to the third connection port 13, and another of which is connected to the pressure alarm 132. When the pressure alarm 132 is in a working state, the pressure alarm 132 passes through the channel in the third shut-off valve 131 and is connected to the third connection port 13. When the pressure alarm 132 has a problem and needs to be repaired or replaced, the third shut-off valve 131 is closed, and then the pressure alarm 132 is taken out from the channel of the third shut-off valve 131, so as to avoid leakage of refrigerant in the anti-integrated component 10. Specifically, the pressure alarm 132 is a pressure switch or other alarm device for monitoring pressure.

[0056] It is understandable that by connecting the pressure detector 122 and the pressure alarm 132 to the second connection port 12 and the third connection port 13 through the second stop valve 121 and the third stop valve 131, on the one hand, refrigerant leakage can be effectively prevented when the pressure detector 122 and the pressure alarm 132 are replaced, and on the other hand, the thread stripping phenomenon of the threads of the second connection port 12 and the third connection port 13 caused by frequent replacement of the pressure detector 122 and the pressure alarm 132 can be avoided. In addition, the second stop valve 121 and the third stop valve 131 are permanently fixed at the second connection port 12 and the third connection port 13, playing the role of fixing the pressure detector 122 and the pressure alarm 132.

[0057] Furthermore, in some embodiments, in order to integrate the signal monitoring element and take into account the function of charging refrigerant at the same time, a fourth connection port 14 and a fourth channel 14a are provided on the integrated component 10. The fourth connection port 14 is connected to the main channel 10a through the fourth channel 14a. The signal monitoring integrated component is also provided with a fourth stop valve 141, which is fixedly connected to the fourth connection port 14.

[0058] Specifically, in some embodiments, the fourth stop valve 141 includes a first flow pipe 1411, a second flow pipe 1412 and a fourth stop valve switch 1413. The first flow pipe 1411 is connected to the fourth connection port 14. When the pipeline to be monitored does not need to be charged with refrigerant, the fourth stop valve switch 1413 is closed, and the second flow pipe 1412 is in a blocked state. When the pipeline to be monitored needs to be charged with refrigerant, the second flow pipe 1412 is connected to the refrigerant pipeline access port, and the fourth stop valve switch 1413 is opened at the same time, the second flow pipe 1412 is connected to the first flow pipe 1411, and the refrigerant enters the pipeline to be monitored through the integrated component 10.

[0059] It is understandable that the integrated component 10 can be a cylinder, a cuboid, a cube, a sphere or other shapes, which are not limited here. The main flow channel 10a in the integrated component 10 can be a straight flow channel connected to the first connection port 11 and the fourth connection port 14, or it can be a flow channel of various other shapes. When the refrigerant flows in the pipeline, if the cross-section of the pipeline is constant, the pressure of the refrigerant at various locations in the pipeline is almost the same. Therefore, as a preferred embodiment, the main flow channel 10a in the integrated component 10 is a straight flow channel, and the cross-sectional size of the main flow channel 10a is the same as the cross-sectional size of the first connection port 11 and the fourth connection port 14. In this way, the position of the pressure detector 122 and the pressure alarm 132 on the integrated component 10 is not restricted, and the pressure monitoring of the refrigerant on the monitored pipeline is more accurate.

[0060] As an example, in this embodiment, the integrated component 10 is a cylinder, the first connection port 11 is arranged at one end of the cylindrical integrated component 10, and the fourth connection port 14 is arranged at the other end. The main flow path 10a in the integrated component 10 is a cylindrical direct current path, the first connection port 11 and the fourth connection port 12 are coaxially connected with the main flow path 10a, and the second connection port 12 and the third connection port 13 are arranged on the side wall of the integrated component 10, and can be arranged at any position of the side wall of the integrated component 10. In order to avoid the structural strength of the integrated component 10 being weakened due to the centralized arrangement of multiple openings, it is preferred that the second connection port 12 and the third connection port 13 are dispersedly arranged on the side wall of the integrated component 10.

[0061] In some other embodiments, the first connection port 11 is disposed at one end of the cylindrical integrated component 10, and the second connection port 12, the third connection port 13 and the fourth connection port 14 are all disposed on the side wall of the integrated component 10, and can be disposed at any position on the side wall of the integrated component 10. Preferably, the second connection port 12, the third connection port 13 and the fourth connection port 14 are dispersedly disposed on the side wall of the integrated component 10.

[0062] It should be noted that, through the different setting positions of the above-mentioned two fourth connection ports 14, the spatial distribution of the pipeline to be monitored connected to the first connection port 11 can be flexibly adjusted and utilized, so as to avoid the situation where the interface of the pipeline to be monitored is inconveniently connected to the first connection port 11 due to insufficient longitudinal or lateral space in the heat pump unit box.

[0063] Furthermore, when the monitored pipeline is charged with refrigerant, after the amount of refrigerant in the monitored pipeline reaches a certain amount, the charging of refrigerant needs to be gradually reduced until it stops. In this process, in order to facilitate the flow limiting of the refrigerant entering the monitored pipeline, the fourth stop valve 141 is provided with a flow limiting member, which can be arranged at the first flow pipe 1411 or the second flow pipe 1412. Preferably, the flow limiting member is arranged at the second flow pipe 1412, and before closing the fourth stop valve switch 1413, the flow limiting member is adjusted first to reduce the amount of refrigerant flowing from the refrigerant inlet into the internal end face of the fourth stop valve switch 1413, thereby reducing the pressure on the internal end face of the fourth stop valve switch 1413, so that the fourth stop valve 141 is closed more easily and quickly.

[0064] See also Figure 4In some embodiments, the flow limiting member 15 includes a first flow limiting plate 151, a second flow limiting plate 152 and a swivel 153. The first flow limiting plate 151 is fixed in the second flow pipe 1412, the swivel 153 is rotatably connected to the second flow pipe, and the second flow limiting plate 152 is fixed in the swivel 153 and is arranged opposite to the first flow limiting plate 151. Specifically, the first flow limiting plate 151 and the first flow limiting plate 152 are circular plates, the first flow limiting plate 151 and the second flow limiting plate 152 are arranged parallel to each other, and the first flow limiting plate 151 and the second flow limiting plate 152 are both provided with a plurality of flow blocking pieces 1511 evenly distributed on the circumference, and spacer holes are formed between adjacent flow blocking pieces 1511, and the refrigerant can pass through the spacer holes. By rotating the swivel 153, the relative positions of the flow blocking pieces 1511 of the first flow limiting plate 151 and the flow blocking pieces 1511 of the second flow limiting plate 152 can be changed, thereby changing the flow rate of the refrigerant after passing through the flow limiting member 15. When refrigerant needs to be charged, the rotating ring 153 is rotated so that the baffles on the first limiting plate 151 and the second limiting plate 152 are completely opposite, and the refrigerant can pass through the spacing holes at the maximum flow rate. When the liquid in the second flow pipe 1412 needs to be limited, the rotating ring 153 drives the second limiting plate 152 to rotate, and the spacing holes on the second limiting plate 152 and the first limiting plate 151 are staggered to reduce the refrigerant flow rate.

[0065] See also Figure 5-7 In some other embodiments, the flow limiting member 15' includes a circular ring seat 151', a blocking cover 152', a plurality of circular arc pieces 153', a retaining spring 154' and an adjusting rod 155'.

[0066] The annular seat 151' is arranged parallel to the cross section of the second flow tube 1412. A slot 151a' is provided in the annular seat 151', and the blocking cover 152' is rotatably provided in the slot 151a'. A plurality of through holes 151b' evenly distributed along the circumference are provided on the annular surface of the annular seat 151', and a plurality of notches 152b' are provided on the blocking cover 152'. The arc piece 153' is sandwiched between the annular seat 151' and the blocking cover 152', and a fixed shaft 153a' is provided on both sides of the arc piece 153'. The fixed shaft 153a' on one side is rotatably provided in the through hole 151b', and the fixed shaft 153a' on the other side is slidably provided in the notch 152b'. A plurality of arc pieces 153' are arranged in an array along the circumference, and a variable-sized adjustment hole 156' is formed in the middle. The retaining spring 154' is located inside the slot. The retaining spring 154' is against the retaining cover 152' on one side toward the center of the retaining cover 152', and is fixed to the annular seat 154' on the other side. The retaining spring 154' is used to prevent the annular seat 151' and the retaining cover 152' from rotating axially at the same time. A notch 151c' is provided on the side of the annular seat 151', and the adjusting rod 155' passes through the notch 151c' and is fixed to the side of the retaining cover 152'. By toggling the adjusting rod 155', the retaining cover 152' is driven to rotate, and the position of the arc piece 153' is adjusted, thereby controlling the size of the adjusting hole 156'. When refrigerant needs to be charged, the adjusting hole 156' is adjusted to the maximum to facilitate the circulation of the refrigerant. When the refrigerant needs to be limited, the adjusting hole 156' is gradually reduced. At the same time, the fourth stop valve switch 1413 is closed, and finally the refrigerant inlet is pulled out from the interface of the second flow channel 1412.

[0067] Furthermore, since the internal pressure of the integrated component 10 is relatively high, it is easy to cause the refrigerant in the integrated component 10 to leak. In order to increase the sealing of the integrated component 10 to prevent the refrigerant from leaking, and to make the first stop valve 111, the second stop valve 121, the third stop valve 131 and the fourth stop valve 141 more convenient to connect with the first connection port 11, the second connection port 12, the third connection port 13 and the fourth connection port 14 respectively, the first connection port 11, the second connection port 12, the third connection port 13 and the fourth connection port 14 are all provided with an integrally welded fixing member 16. The fixing member 16 is provided with a thread on the inner side, and one of the through pipes of the first stop valve 111, the second stop valve 121, the third stop valve 131 and the fourth stop valve 141 is threadedly connected to the integrated component 10 through the fixing member 16.

[0068] Furthermore, in some embodiments, sealing rings are provided at the connection points between the fixing member 16 and the first stop valve 111 , the second stop valve 121 , the third stop valve 131 and the fourth stop valve 141 to further enhance the sealing of the integrated component 10 .

[0069] See also Figure 1 and Figure 8Furthermore, in some embodiments, in order to secure the integrated component 10 on the maintenance panel of the heat pump unit, a fixing seat 17 is provided at the connection between the fourth stop valve 131 and the integrated component 10 .

[0070] An embodiment of the present application also provides a heat pump unit, comprising the above-mentioned signal monitoring integrated component.

[0071] Compared with the prior art, the beneficial effects of the technical solution of this application are:

[0072] (1) The pressure detector, the pressure alarm and the pipeline to be detected are centrally fixed to the integrated component through the stop valve to form an integrated component, and the integrated component is arranged near the maintenance panel of the heat pump unit, so as to facilitate the monitoring of the pressure of the pipeline to be monitored so as to understand the status of the pipeline to be monitored at any time, and to facilitate maintenance while better preventing the leakage of refrigerant in the pipeline;

[0073] (2) A fourth connection port and a fourth stop valve are provided on the integrated component to facilitate access to the refrigerant inlet from the second flow channel of the fourth stop valve to charge the refrigerant into the pipeline to be monitored.

[0074] (3) When charging the refrigerant into the pipeline to be monitored, the flow rate of the refrigerant in the pipeline can be adjusted at any time according to the pressure information obtained by setting a flow limiting device;

[0075] At the same time, before the refrigerant charging is stopped, the flow rate of the refrigerant inlet flowing into the internal end face of the fourth stop valve switch is reduced by adjusting the flow limiting member to reduce the pressure on the internal end face of the fourth stop valve switch, so that the fourth stop valve is closed more easily and quickly, and the amount of refrigerant charged is ensured to be more accurate;

[0076] (4) By integrally welding the fasteners at the interfaces of the integrated components, the fastening of each stop valve to each interface is facilitated, and at the same time, the sealing performance is improved;

[0077] (5) Sealing rings are provided at each connection to further enhance the sealing of the entire assembly.

[0078] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
