Description

Technical Field

[0001] The present invention relates to the technical field of steam heat pumps, in particular to an energy-saving system for achieving zero steam consumption in a brewing workshop through a steam heat pump. Background Art

[0002] Brewing processes such as saccharification and sterilization require large amounts of steam, which generates a significant amount of liquefied wastewater. Previously, this wastewater was simply discharged. However, with the increasing adoption of energy-saving and environmentally friendly production concepts, a growing number of devices are now available on the market that filter and recycle steam wastewater, including heat recovery.

[0003] Steam heat pumps, as one type of energy-saving equipment, achieve "zero wastewater consumption" by recovering waste heat from wastewater. However, in actual production processes, due to the temperature fluctuations of wastewater, the heat of lower-temperature wastewater cannot be fully recovered, while the heat exchange of higher-temperature wastewater is difficult to quickly carry out, resulting in reduced heat exchange efficiency and quality. Summary of the Invention

[0004] The purpose of the present invention is to provide an energy-saving system that achieves zero steam consumption in a brewing workshop through a steam heat pump, so as to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an energy-saving system for achieving zero steam consumption in a brewing workshop through a steam heat pump, comprising an evaporator, a condenser, a compressor, a control cabinet and a pressure reducing valve, the evaporator being respectively provided with a waste liquid inlet and a waste liquid outlet, a flow control and pressure regulating device being installed on the waste liquid inlet, the compressor being connected to the evaporator through a pipeline, the evaporator being connected to the condenser through a pipeline, one end of the pressure reducing valve being connected to the evaporator through a pipeline, and the other end of the pressure reducing valve being connected to the condenser through a pipeline, a heating inlet and a heating outlet being respectively provided on the condenser, and the flow control and pressure regulating device being connected to a pumping device through a pipeline.

[0006] The control cabinet is equipped with a control system that controls the entire energy-saving system. The pumping device is used to transport the wastewater after steam cooling in the brewing workshop to the flow control and pressure regulating device.

[0007] During operation, the pumping device transports the wastewater to the flow control and pressure regulating device through the pipeline. After passing through the flow control and pressure regulating device, the wastewater enters the evaporator from the waste liquid inlet. The residual heat of the waste liquid heats the refrigerant in the evaporator. The heated refrigerant enters the compressor, and the wastewater after heat exchange is discharged from the waste liquid outlet, completing the purpose of steam wastewater heat recovery.

[0008] The heated refrigerant enters the compressor, where it is compressed into a high-temperature, high-pressure gas before being sent to the condenser. Simultaneously, room-temperature pure water enters the condenser from the heating inlet, where it comes into contact with the high-temperature, high-pressure refrigerant. The room-temperature pure water absorbs heat and forms steam, which is then transported from the heating outlet to the steam port where it will be used. After releasing the heat, the high-temperature, high-pressure refrigerant changes from gas to liquid. After passing through the pressure reducing valve, it returns to a low-temperature, low-pressure liquid and flows back to the evaporator, beginning the next cycle.

[0009] Furthermore, the flow control and pressure regulating device includes a flow control component, a hollow tube and a flange tube. A cache component is installed at one end of the flow control component, the cache component is slidingly connected to the flange tube, the flange tube is connected to the pumping device through a pipeline, a pressure regulating component is installed in the hollow tube, the other end of the flow control component is connected to the pressure regulating component, the hollow tube is connected to the waste liquid inlet, the hollow tube is connected to the first infusion device through the pipeline, and the flow control component is connected to the second infusion device through the pipeline.

[0010] The first infusion device is used to input or output hydraulic oil into the hollow tube, and the second infusion device is used to input or output hydraulic oil into the flow control component.

[0011] Furthermore, the flow control assembly includes a ring frame, on which several flow control members are rotatably mounted, an adjusting gear ring is rotatably mounted on the ring frame, the adjusting gear ring is meshed with the flow control member for transmission, a ring cover is mounted on the ring frame, a sliding shell is mounted inside the ring cover, an adjusting slider is mounted on the adjusting gear ring, the adjusting slider is slidably connected to the sliding shell, the sliding shell is slidably connected to the adjusting gear ring, a connecting tube is mounted at one end of the sliding shell, the connecting tube passes through the ring cover and is connected to the second infusion device, one end of the ring cover is connected to the pressure regulating assembly, and the other end of the ring cover is connected to the cache assembly.

[0012] A seal is provided between the sliding housing and the adjusting gear ring.

[0013] Furthermore, the ring frame includes an inner ring and an outer ring, a connecting rod is installed between the inner ring and the outer ring, a ring cover is installed on the outer ring, an adjusting gear ring is rotatably installed on the outer ring, one end of the spoiler is rotatably connected to the inner ring, and the other end of the spoiler is rotatably connected to the outer ring.

[0014] Furthermore, the spoiler includes a rotating rod, on which a spoiler is installed. One end of the rotating rod is rotatably connected to the inner ring, and the other end of the rotating rod passes through the outer ring and is installed with a gear. The gear is engaged with the adjusting gear ring for transmission, and one end of the rotating rod with the gear installed is rotatably connected to the outer ring.

[0015] A temperature sensor is provided in the evaporator for detecting the temperature of the incoming waste liquid. When a high temperature is detected, the control system turns on the second infusion device, which inputs hydraulic oil into the sliding shell through the connecting pipe. The hydraulic oil entering the sliding shell squeezes one side of the adjustment slider. After the adjustment slider is compressed, it drives the adjustment gear to rotate around the outer ring. The adjustment gear ring drives the gear meshing with it to rotate. The gear drives the rotating rod to rotate. The rotating rod drives the baffle to deflect, thereby increasing the gap between the baffles and the flow area. This increases the speed at which wastewater enters the evaporator. At the same time, the control system accelerates the flow rate of the refrigerant, and the refrigerant quickly absorbs the heat in the waste liquid, thereby improving the heat exchange efficiency.

[0016] When the temperature sensor detects that the temperature of the wastewater is low, the control system controls the second infusion device to pump out the hydraulic oil in the sliding shell through the connecting pipe. After the hydraulic oil is pumped out, the pressure in the sliding shell decreases, the adjusting slider slides in the opposite direction, and drives the adjusting slider to drive the adjusting gear ring to rotate in the opposite direction, and the adjusting gear ring drives the gear to rotate in the opposite direction. The gear drives the baffle to deflect in the opposite direction through the rotating rod, and the gap between the baffles is reduced, reducing the flow area, so that the speed at which the wastewater enters the evaporator is slowed down. At the same time, the control system slows down the flow rate of the refrigerant in the evaporator to ensure sufficient heat exchange between the two.

[0017] The deflection of the spoiler is positively correlated with the wastewater temperature.

[0018] Furthermore, the pressure regulating assembly includes a sliding tube, which is slidably connected to the hollow tube, and a number of guide tubes are installed in the sliding tube, and a guide rod is slidably installed in the guide tube. One end of the guide rod is connected to a sliding ring, and the sliding ring is slidably installed in the hollow tube. An adjusting spring is installed between the sliding ring and the sliding tube, and an induction switch is installed on the sliding tube.

[0019] The faster the pumping device operates, the faster the wastewater flow rate input to the flow control and pressure regulating device, the greater the impact of the wastewater on the flow blocking element, and the greater the displacement generated by the flow control component, making it easier for the induction switch to be triggered at a high operating speed of the pumping device. In order to eliminate the influence of the wastewater flow rate on the flow control component, the control system turns on the first infusion device according to the operating speed of the pumping device. The first infusion device inputs hydraulic oil into the regulating cavity through the liquid outlet. The hydraulic oil pushes the sliding ring to move in the hollow tube. The sliding ring pre-loads the regulating spring, increasing the stiffness of the regulating spring and increasing the thrust required by the flow control component to compress the regulating spring through the sliding ring. This achieves the purpose of offsetting the thrust caused by the increase in flow rate, ensuring that the flow control component can generate corresponding, proportionally controllable displacement at different wastewater flow rates, so that the difficulty of triggering the induction switch is consistent at different wastewater flow rates.

[0020] Furthermore, a regulating cavity is provided in the hollow tube, a liquid outlet is provided on the hollow tube, the liquid outlet is connected to the regulating cavity, the liquid outlet is connected to the first infusion device through a pipeline, a convex ring is provided in the hollow tube, a first corrugation is provided in the hollow tube, and a second corrugation is provided on the sliding tube.

[0021] When the temperature of the wastewater input to the evaporator is low, as the several baffles are closed as a whole, the operating speed of the pumping device remains unchanged. At this time, the wastewater in the flange pipe increases, resulting in an increase in the local pressure in the area, and the impact force on the baffle increases, causing the baffle to drive the entire flow control assembly to move horizontally toward the hollow pipe. During movement, the ring cover pushes the sliding tube to slide in the hollow tube, the adjusting spring is compressed, and the guide tube slides along the guide rod. The guide tube and the guide rod are used to maintain the stability of the adjusting spring when it is compressed. When the wastewater temperature rises, the baffle gradually opens, and the wastewater in the flange pipe area is discharged. The water pressure in the area gradually decreases, the impact on the baffle weakens, the adjusting spring rebounds, and drives the entire flow control assembly to move in the opposite direction and reset through the sliding tube, thereby achieving the purpose of local water pressure regulation, preventing leakage due to excessive water pressure, and providing primary protection for the flow control of the flow control assembly.

[0022] Furthermore, the cache assembly includes a cache tube, which is installed on one side of the ring cover. The cache tube is provided with several cache grooves, elastic bags are installed in the cache grooves, a cache plate is installed in the cache grooves, an electric valve is provided on the cache plate, and the cache tube is slidably connected to the flange tube.

[0023] When the temperature of the wastewater transported by the pumping device remains low and the water pressure in the flange pipe continues to rise to a critical value, the flow control component drives the entire flow control assembly to move horizontally, the ring cover pushes the sliding tube, and the induction switch at the end of the sliding tube moves to the convex ring position and is squeezed with the convex ring. The second corrugation on the sliding tube moves to the first corrugation and the two come into contact. After the induction switch is pressurized, it sends an electrical signal to the control system. After receiving the electrical signal, the control system reduces the operating speed of the pumping device and reduces the speed of wastewater transportation.

[0024] When the induction switch moves toward the convex ring position, the cache tube at the other end of the ring cover moves along with the ring cover until the cache tube is offset from the flange tube and the wastewater contacts the cache plate. When the induction switch is triggered, the control system synchronously opens the electric valve, and the high-pressure wastewater is squeezed into the elastic bag, thereby alleviating the local high water pressure. As the control system reduces the speed of the pumping device, the wastewater decreases, the water pressure at the flange pipe decreases, the elastic bag contracts and squeezes out the wastewater inside. Due to the contact between the first corrugation and the second corrugation, the local friction between the sliding tube and the hollow tube is increased, so that the speed at which the sliding tube rebounds and resets under the action of friction is slower than the contraction speed of the elastic bag. After the elastic bag contracts, the sliding tube drives the flow control component to rebound and reset, the electrical signal generated by the induction switch disappears, and the control system closes the electric valve, thereby achieving the purpose of local water pressure overload regulation, further preventing leakage or damage to the mechanism due to water pressure overload, and providing secondary protection for the flow control of the flow control component.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The second infusion device is used to input or output hydraulic oil into the sliding shell, so that the adjusting slider slides in the sliding shell. The adjusting slider drives the adjusting gear ring to deflect, thereby driving several baffles to deflect synchronously. After the deflection, the gap between the baffles changes, so that the wastewater flow area changes, so that the wastewater heat is taken away faster or more fully by the refrigerant, thereby achieving the purpose of improving the wastewater heat recovery rate and recovery speed.

[0027] 2. Hydraulic oil is injected into the regulating chamber using the first infusion device. The hydraulic oil pushes the sliding ring to move within the hollow tube. The sliding ring preloads the regulating spring, increasing its stiffness and increasing the thrust required by the flow control component to compress the regulating spring through the sliding ring. This offsets the thrust caused by the increased flow rate, ensuring that the flow control component produces a corresponding, proportionally controllable displacement at different wastewater flow rates, making the induction switch trigger with consistent ease at different wastewater flow rates.

[0028] 3. The sliding tube is used to convert the high-pressure impact force on the flow control component into compression of the regulating spring, thereby achieving the purpose of local water pressure regulation, preventing leakage due to excessive water pressure, and providing primary protection for the flow control of the flow control component.

[0029] 4. When the temperature of the wastewater delivered by the pumping device remains low and the water pressure in the flange pipe continues to rise to a critical value, the ring cover drives the induction switch to be triggered by pressure, and at the same time drives the buffer component on the other side to open, so that the elastic bag can temporarily accommodate the high-pressure wastewater, thereby achieving the purpose of local water pressure overload regulation, further preventing leakage or mechanism damage due to water pressure overload, and providing secondary protection for the flow control of the flow control component.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] like Figures 1-10 As shown, the present invention provides a technical solution for an energy-saving system for achieving zero steam consumption in a brewing workshop through a steam heat pump: the system comprises an evaporator 1, a condenser 2, a compressor 3, a control cabinet 5 and a pressure reducing valve 4, the evaporator 1 is respectively provided with a waste liquid inlet 11 and a waste liquid outlet 12, the waste liquid inlet 11 is installed with a flow control and pressure regulating device 6, the compressor 3 is connected to the evaporator 1 through a pipeline, the evaporator 1 is connected to the condenser 2 through a pipeline, one end of the pressure reducing valve 4 is connected to the evaporator 1 through a pipeline, and the other end of the pressure reducing valve 4 is connected to the condenser 2 through a pipeline, the condenser 2 is respectively provided with a heating inlet 21 and a heating outlet 22, and the flow control and pressure regulating device 6 is connected to a pumping device through a pipeline.

[0043] The control cabinet 5 is provided with a control system for controlling the entire energy-saving system. The pumping device is used to transport the waste water after steam cooling in the brewing workshop to the flow control and pressure regulating device 6.

[0044] During operation, the pumping device transports the wastewater to the flow control and pressure regulating device 6 through the pipeline. After passing through the flow control and pressure regulating device 6, the wastewater enters the evaporator 1 through the waste liquid inlet 11. The residual heat of the waste liquid heats the refrigerant in the evaporator 1. The heated refrigerant enters the compressor 3, and the wastewater after heat exchange is discharged from the waste liquid outlet 12, completing the purpose of steam wastewater heat recovery.

[0045] The heated refrigerant enters compressor 3, where it is compressed into a high-temperature, high-pressure gas and then fed into condenser 2. Simultaneously, room-temperature pure water enters condenser 2 through heating inlet 21, where it comes into contact with the high-temperature, high-pressure refrigerant. The room-temperature pure water absorbs heat and forms steam, which is then transported through heating outlet 22 to the steam port for future use. After releasing heat, the high-temperature, high-pressure refrigerant changes from gas to liquid. After passing through pressure reducing valve 4 and being decompressed, it returns to a low-temperature, low-pressure liquid and flows back into evaporator 1, beginning the next cycle.

[0046] The flow control and pressure regulating device 6 includes a flow control component 61, a hollow tube 63, and a flange tube 62. A buffer component 65 is installed at one end of the flow control component 61. The buffer component 65 is slidably connected to the flange tube 62. The flange tube 62 is connected to the pumping device via a pipeline. A pressure regulating component 64 is installed in the hollow tube 63. The other end of the flow control component 61 is connected to the pressure regulating component 64. The hollow tube 63 is connected to the waste liquid inlet 11. The hollow tube 63 is externally connected to a first infusion device via a pipeline. The flow control component 61 is externally connected to a second infusion device via a pipeline. The first infusion device is used to input or output hydraulic oil into or out of the hollow tube 63, and the second infusion device is used to input or output hydraulic oil into or out of the flow control component 61.

[0047] The flow control assembly 61 includes a ring frame 611, on which a plurality of flow control elements 612 are rotatably mounted. An adjustment ring gear 614 is rotatably mounted on the ring frame 611, meshing with the flow control elements 612. A ring cover 613 is mounted on the ring frame 611, within which a sliding housing 615 is mounted. An adjustment slider 6141 is mounted on the adjustment ring gear 614, which is slidably connected to the sliding housing 615. The sliding housing 615 is slidably connected to the adjustment ring gear 614. A connecting tube 616 is mounted at one end of the sliding housing 615, which passes through the ring cover 613 and is connected to the second infusion device. One end of the ring cover 613 is connected to the pressure regulating assembly 64, and the other end of the ring cover 613 is connected to the buffer assembly 65. A seal is provided between the sliding housing 615 and the adjustment ring gear 614.

[0048] The ring frame 611 includes an inner ring 6111 and an outer ring 6113, a connecting rod 6112 is installed between the inner ring 6111 and the outer ring 6113, a ring cover 613 is installed on the outer ring 6113, an adjusting gear ring 614 is rotatably installed on the outer ring 6113, one end of the spoiler 612 is rotatably connected to the inner ring 6111, and the other end of the spoiler 612 is rotatably connected to the outer ring 6113.

[0049] The spoiler 612 includes a rotating rod 6122, on which a spoiler 6121 is installed. One end of the rotating rod 6122 is rotatably connected to the inner ring 6111, and the other end of the rotating rod 6122 passes through the outer ring 6113 and is installed with a gear 6123. The gear 6123 is engaged with the adjusting gear ring 614 for transmission, and one end of the rotating rod 6122 on which the gear 6123 is installed is rotatably connected to the outer ring 6113.

[0050] The pressure regulating assembly 64 includes a sliding tube 641, which is slidably connected to the hollow tube 63. Several guide tubes 642 are installed in the sliding tube 641. A guide rod 643 is slidably installed in the guide tube 642. One end of the guide rod 643 is connected to a sliding ring 646. The sliding ring 646 is slidably installed in the hollow tube 63. An adjusting spring 644 is installed between the sliding ring 646 and the sliding tube 641. An induction switch 645 is installed on the sliding tube 641.

[0051] The faster the pumping device operates, the faster the wastewater flow rate input to the flow control and pressure regulating device 6 becomes, the greater the impact of the wastewater on the flow blocking element 612, and the greater the displacement of the flow control assembly 61, making it easier for the inductive switch 645 to be triggered at high pumping device operating speeds. To eliminate the effect of the wastewater flow rate on the flow control assembly 61, the control system activates the first infusion device according to the pumping device operating speed. The first infusion device injects hydraulic oil into the regulating chamber 634 through the liquid outlet 632. The hydraulic oil pushes the sliding ring 646 to move within the hollow tube 63. The sliding ring 646 preloads the regulating spring 644, increasing the stiffness of the regulating spring 644 and increasing the thrust required by the flow control assembly 61 to compress the regulating spring 644 through the sliding ring 646. This offsets the thrust caused by the increased flow rate, ensuring that the flow control assembly 61 can produce corresponding, proportionally controllable displacement at different wastewater flow rates, making the inductive switch 645 trigger with consistent ease at different wastewater flow rates.

[0052] An adjusting cavity 634 is provided in the hollow tube 63, and a liquid outlet 632 is provided on the hollow tube 63. The liquid outlet 632 is communicated with the adjusting cavity 634, and the liquid outlet 632 is connected to the first infusion device through a pipeline. A convex ring 633 is provided in the hollow tube 63, a first corrugation 631 is provided in the hollow tube 63, and a second corrugation 6411 is provided on the sliding tube 641.

[0053] The cache assembly 65 includes a cache tube 651, which is installed on one side of the ring cover 613. The cache tube 651 is provided with a plurality of cache grooves 6511. Elastic bags 654 are installed in the cache grooves 6511. A cache plate 652 is installed in the cache grooves 6511. The cache plate 652 is provided with an electric valve 653. The cache tube 651 is slidably connected to the flange tube 62.

[0054] The working principle of the present invention is as follows: a temperature sensor is provided in the evaporator 1 for detecting the temperature of the incoming waste liquid. When a high temperature is detected, the control system turns on the second infusion device, and the second infusion device inputs the hydraulic oil into the sliding shell 615 through the connecting pipe 616. The hydraulic oil entering the sliding shell 615 squeezes one side of the adjusting slider 6141. After the adjusting slider 6141 is pressurized, it drives the adjusting gear ring 614 to rotate around the outer ring 6113. The adjusting gear ring 614 drives the gear 6123 meshing with it to rotate. The gear 6123 drives the rotating rod 6122 to rotate. The rotating rod 6122 drives the baffle 6121 to deflect, thereby increasing the gap between the baffles 6121 and the flow area. This increases the speed at which waste water enters the evaporator 1. At the same time, the control system accelerates the flow rate of the refrigerant, and the refrigerant quickly absorbs the heat in the waste liquid, thereby improving the heat exchange efficiency.

[0055] When the temperature sensor detects that the temperature of the wastewater is low, the control system controls the second infusion device to pump out the hydraulic oil in the sliding shell 615 through the connecting pipe 616. After the hydraulic oil is pumped out, the pressure in the sliding shell 615 decreases, the adjusting slider 6141 slides in the opposite direction, and drives the adjusting slider 6141 to drive the adjusting gear ring 614 to rotate in the opposite direction. The adjusting gear ring 614 drives the gear 6123 to rotate in the opposite direction. The gear 6123 drives the baffle 6121 to deflect in the opposite direction through the rotating rod 6122. The gap between the baffles 6121 is reduced, reducing the flow area, slowing down the speed at which the wastewater enters the evaporator 1. At the same time, the control system slows down the flow rate of the refrigerant in the evaporator 1 to ensure sufficient heat exchange between the two. The deflection amount of the baffle 6121 is positively correlated with the wastewater temperature.

[0056] When the temperature of the wastewater input to the evaporator 1 is low, as the plurality of flow-blocking members 612 are closed as a whole, the operating speed of the pumping device remains unchanged. At this time, the wastewater in the flange pipe 62 increases, resulting in an increase in the local pressure in the area, and the impact force on the flow-blocking member 612 increases, causing the flow-blocking member 612 to drive the entire flow control assembly 61 to move horizontally toward the hollow pipe 63. During the movement, the ring cover 613 pushes the sliding pipe 641, causing the sliding pipe 641 to slide in the hollow pipe 63, the adjusting spring 644 is compressed, and the guide pipe 642 slides along the guide rod 643. The guide tube 642 and the guide rod 643 are used to maintain the stability of the adjustment spring 644 when it is compressed. When the wastewater temperature rises, the flow blocking member 612 gradually opens, and the wastewater in the flange pipe 62 area is discharged. The water pressure in the area gradually decreases, and the impact on the flow blocking member 612 is weakened. The adjustment spring 644 rebounds and drives the entire flow control component 61 to move in the opposite direction and reset through the sliding tube 641, thereby achieving the purpose of local water pressure regulation, preventing leakage due to excessive water pressure, and providing primary protection for the flow control of the flow control component 61.

[0057] When the temperature of the wastewater transported by the pumping device remains low and the water pressure in the flange pipe 62 continues to rise to a critical value, the flow blocking member 612 drives the entire flow control assembly 61 to move horizontally, the ring cover 613 pushes the sliding tube 641, and the inductive switch 645 at the end of the sliding tube 641 moves to the position of the convex ring 633 and is squeezed by the convex ring 633. The second corrugation 6411 on the sliding tube 641 moves to the first corrugation 631 and the two contact each other. After being pressurized, the inductive switch 645 sends an electrical signal to the control system. After receiving the electrical signal, the control system reduces the operating speed of the pumping device and reduces the speed of wastewater transportation.

[0058] When the induction switch 645 moves toward the convex ring 633, the buffer tube 651 at the other end of the ring cover 613 moves along with the ring cover 613 until the buffer tube 651 is offset from the flange tube 62, and the waste water contacts the buffer plate 652. When the induction switch 645 is triggered, the control system synchronously opens the electric valve 653, and the high-pressure waste water is squeezed into the elastic bag 654, thereby relieving the local high water pressure. As the control system reduces the speed of the pumping device, the waste water decreases, the water pressure at the flange tube 62 decreases, the elastic bag 654 contracts and squeezes out the waste water inside. The contact between the corrugation 631 and the second corrugation 6411 increases the local friction between the sliding tube 641 and the hollow tube 63, so that the sliding tube 641 rebounds and resets slower than the contraction speed of the elastic bag 654 under the action of the friction. After the elastic bag 654 contracts, the sliding tube 641 drives the flow control component 61 to rebound and reset, the electrical signal generated by the induction switch 645 disappears, and the control system closes the electric valve 653, thereby achieving the purpose of local water pressure overload regulation, further preventing leakage or mechanism damage caused by water pressure overload, and providing a secondary guarantee for the flow control of the flow control component 61.

[0059] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
