Description

Technical Field

[0001] The invention relates to the technical field of air-conditioning equipment, in particular to a flushing bypass pipe of an air-conditioning water system. Background Art

[0002] During the installation process of air conditioning water systems, impurities such as rust, welding slag, and sand are inevitably present in the pipes. If these impurities remain in the system, they can adversely affect the normal operation of the air conditioning equipment. For example, impurities can clog the heat exchanger and water pump in the air conditioning unit, reducing heat exchange efficiency and resulting in poor cooling or heating results. They can also increase wear on equipment such as the water pump, shortening its service life.

[0003] To ensure the cleanliness of air conditioning water systems, flushing is often necessary. Traditional flushing of air conditioning water systems often presents challenges due to the design and installation locations of individual devices. For example, some equipment cannot withstand excessive flushing water flow rates and pressures, which can damage them. This is why flushing bypass pipes in air conditioning water systems have emerged. By installing a flushing bypass pipe, the flushing water flow can be directed to a bypass pipe during the flushing process, bypassing equipment that cannot withstand high flow and pressure, thereby preventing damage to these devices.

[0004] The existing bypass pipe structure is relatively simple, usually with only one "U"-shaped pipe connected to the inlet and outlet water pipes of the equipment. The following problems still exist during use: 1. Its size is fixed, so it cannot be installed according to the actual use requirements of the equipment, which has limitations during use; 2. When the bypass pipe is installed between two groups of equipment, the flushing water needs to be guided to the subsequent equipment, and when the bypass pipe is installed at the end of the air-conditioning water system, the flushing water needs to be discharged at this time. However, the existing bypass pipe cannot selectively use different functions when facing the needs of drainage or continuous flushing of subsequent equipment; 3. The flow direction of the flushing water cannot be controlled during flushing, and backflow problems are prone to occur, which may cause impurities to enter the equipment and affect operation. Summary of the Invention

[0005] In response to the deficiencies in the prior art, the present invention provides an air conditioning water system flushing bypass pipe, which solves the technical problems of the existing bypass pipe, such as installation limitations, restricted usage scenarios, and easy backflow.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solutions: a flushing bypass pipe for an air conditioning water system, comprising a fixed plate, a flow direction control assembly being mounted on the bottom of the fixed plate, a flexible hose and a connecting pipe being flange-connected to both sides of the flow direction control assembly, an end of the flexible hose away from the flow direction control assembly being flange-connected to a water inlet pipe, an adjustment assembly being mounted on the water inlet pipe, and the adjustment assembly being movably connected to the fixed plate; a filter assembly being fixedly connected to the filter assembly at one end of the connecting pipe away from the flow direction control assembly, the filter assembly being fixedly connected to the fixed plate via a fixing ring, and an outlet pipe being fixedly connected to one side of the filter assembly;

[0007] The flow direction control assembly includes a valve housing installed at the bottom of the fixed plate, a valve core is provided in the valve housing, a valve stem is fixedly connected to the valve core, one end of the valve stem extends to the outside of the valve housing and is fixedly connected to an operating handle, a switching channel is opened in the valve core, a one-way flow stop is embedded in the switching channel, two groups of pipe joints respectively connected to the telescopic hose and the connecting pipe are fixed on the outer wall of the valve housing, and a drain pipe is fixed at the bottom of the valve housing.

[0008] Preferably, the switching channel consists of channel one and channel two, channel one and channel two are in a "T"-shaped structure and are interconnected, and the one-way flow stop is located in channel one.

[0009] Preferably, the one-way flow stop member includes a spring installed in channel one, one end of the spring is fixed with a baffle, and a plurality of through holes distributed in a ring shape are opened near the edge of the baffle. In the non-working state, the through holes on the baffle are tightly sealed with the inner wall of the valve core.

[0010] Preferably, a flow direction indicating arrow is provided on the operating handle.

[0011] Preferably, the adjustment assembly includes a movable plate hinged to one end of the fixed plate, an adjustment hole is opened on the movable plate, a sliding sleeve fixed to the outer wall of the water inlet pipe is provided at the adjustment hole, the sliding sleeve is fixed to the outer wall of the water inlet pipe, and a bolt is threadedly connected to the side wall of the sliding sleeve.

[0012] Preferably, the filter assembly includes a shell fixedly connected above the fixed plate, the shell is connected to one end of the connecting pipe, a filter element is installed in the shell, a cleaning assembly is provided on the outside of the filter element, and an inspection plate is installed on the side of the shell away from the water outlet pipe by screws.

[0013] Preferably, the cleaning assembly includes a scraper ring sleeved on the outer wall of the filter element, an operating rod is fixed to the scraper ring, a fixing block is sleeved on one end of the operating rod, and the fixing block is fixed to the inner wall of the shell.

[0014] Preferably, flow direction marks are provided on the outer walls of the water inlet pipe and the water outlet pipe.

[0015] By means of the above technical solution, the present invention provides a flushing bypass pipe for an air conditioning water system, which has at least the following beneficial effects:

[0016] 1. The flushing bypass pipe of the air conditioning water system is equipped with a flow direction control component. Since a switching channel is provided in the valve core, when the valve core rotates, when the switching channel connects the telescopic hose and the drain pipe, the flushing water can be directly discharged from the drain pipe. When the switching channel connects the telescopic hose and the connecting pipe, the flushing water can continue to be transported to subsequent equipment to achieve the purpose of continuous flushing. Different functions can be selectively used according to the installation position of the bypass pipe.

[0017] 2. The flushing bypass pipe of the air conditioning water system is equipped with a one-way flow stop. When the flushing water is transported to the subsequent equipment, it can overcome the elastic force of the spring and flow backward from the through hole on the baffle. Conversely, when the flushing water flows back, the baffle will block the switching channel, thereby achieving the effect of preventing backflow and preventing impurities from entering the equipment in reverse and causing damage to it.

[0018] 3. The flushing bypass pipe of the air conditioning water system is equipped with a telescopic hose and an adjustment component. Under the action of the telescopic hose, the distance between the water inlet pipe and the water outlet pipe can be adjusted to meet the installation requirements of different equipment. The movable plate can drive the water inlet pipe to rotate, thereby realizing the inclined installation of the water inlet pipe to meet the installation requirements of different angles.

[0026] 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.

[0027] The air conditioning water system is an important part of the central air conditioning system. It is mainly used to transport and distribute cold air so that the air conditioning equipment can operate normally and achieve the purpose of regulating indoor temperature, humidity and other environmental parameters.

[0028] Example 1:

[0029] Due to the existing installation limitations, limited usage scenarios and technical defects of easy backflow, please refer to Figure 1-Figure 4The embodiment provides an air conditioning water system flushing bypass pipe, which can selectively use different functions according to the installation position of the bypass pipe, such as direct drainage or continued flushing of subsequent equipment, and has the advantages of anti-backflow and wide application range. The bypass pipe includes a fixed plate 1, a flow control component 2 is installed at the bottom of the fixed plate 1, and a flexible hose 3 and a connecting pipe 6 are flange-connected on both sides of the flow control component 2. The end of the flexible hose 3 away from the flow control component 2 is flange-connected to the water inlet pipe 4, and the water inlet pipe 4 is installed with an adjusting component 5, which is movably connected to the fixed plate 1; the end of the connecting pipe 6 away from the flow control component 2 is fixedly connected to the filter component 7, and the filter component 7 is fixed to the fixed plate 1 through a fixing ring 8, and a water outlet pipe 9 is fixed on one side of the filter component 7; by reasonably arranging the various components, such as using the method The flange connection is convenient for disassembly and maintenance. The flow direction control component 2 can control the discharge of flushing water or continue to transport it to subsequent equipment. The adjustment component 5 is movably connected to the fixed plate 1 to adjust the position of the water inlet pipe 4, making the bypass pipe structure more flexible and compact, improving the installation convenience and overall performance of the bypass pipe, and adapting to different usage scenarios and installation requirements. The filter component 7 can be used to filter impurities in the flushing water to prevent impurities from entering subsequent equipment during continuous flushing; when in use, the flushing water enters the flow direction control component 2 through the water inlet pipe 4 and the telescopic hose 3, and the flushing water flow direction is selected according to the actual installation position. The flow direction can be divided into two paths, one is directly discharged from the bottom of the flow direction control component 2, and the other enters the filter component 7 along the connecting pipe 6. After filtration, it enters the subsequent equipment through the outlet pipe 9 for flushing operations.

[0030] The existing bypass pipe has a simple structure and cannot be used selectively when facing drainage or continuous flushing of subsequent equipment. For this problem, please refer to Figure 2 and Figure 3 The flow direction control assembly 2 includes a valve housing 201 mounted on the bottom of the fixed plate 1. A valve core 202 is provided in the valve housing 201. A valve stem 203 is fixed to the valve core 202. One end of the valve stem 203 extends to the outside of the valve housing 201 and is fixed to an operating handle 204. A switching channel 2021 is provided in the valve core 202. A one-way flow stop 2022 is embedded in the switching channel 2021. Two sets of pipe joints 205 connected to the telescopic hose 3 and the connecting pipe 6 are fixed on the outer wall of the valve housing 201. A drain pipe 206 is fixed to the bottom of the valve housing 201. ; By setting the valve core 202, the valve stem 203 and the operating handle 204, it is convenient for the operator to control the flow direction of the flushing water. The setting of the switching channel 2021 and the one-way stop member 2022 can effectively prevent the backflow of the flushing water and ensure that the fluid flows in a predetermined direction. When the switching channel 2021 connects the telescopic hose 3 and the drain pipe 206, the flushing water can be directly discharged from the drain pipe 206. When the switching channel 2021 connects the telescopic hose 3 and the connecting pipe 6, the flushing water can continue to be transported to the subsequent equipment to achieve the purpose of continuous flushing.

[0031] Furthermore, the switching channel 2021 is composed of a channel 1 20211 and a channel 2 20212. The channel 1 20211 and the channel 2 20212 are in a T-shaped structure and are interconnected. The one-way flow stop 2022 is located in the channel 1 20211. When drainage is required, the valve core 202 is rotated. At this time, one end of the channel 1 20211 is connected to the drain pipe 206, and the channel 2 20212 is connected to the pipe joint 205 near the position of the telescopic hose 3. In this way, the flushing water can directly enter the drain pipe 206 along the switching channel 2021 and be discharged. When continuous flushing is required, the valve core 202 is rotated. At this time, Figure 3 As shown, channel 1 20211 connects the two pipe joints 205, while channel 2 20212 is blocked, and the flushing water can only be transported to the rear along the switching channel 2021, so that the flushing water can continuously flush the subsequent equipment.

[0032] The existing bypass pipe cannot control the flow direction of flushing water during flushing, and backflow is prone to occur, which causes impurities to enter the equipment and affect operation. To address this problem, the one-way flow stop 2022 includes a spring 20221 installed in the channel 1 20211, and one end of the spring 20221 is fixedly connected to a baffle 20222. The baffle 20222 is provided with a plurality of through holes distributed in an annular shape near the edge. In the non-working state, the through holes on the baffle 20222 are tightly sealed with the inner wall of the valve core 202; the arrangement of the spring 20221 and the baffle 20222 enhances the flow-stopping effect of the one-way flow stop 2022, so that the valve core 202 can be easily opened. Figure 3 The arrow shown in the figure is the reference determination direction. When the flushing water flows in the forward direction, the spring 20221 is compressed, and the through hole on the baffle 20222 allows the flushing water to pass through; when the flushing water flows in the reverse direction, the spring 20221 is extended, and the through hole on the baffle 20222 is blocked, preventing the flushing water from flowing back, thereby achieving the purpose of preventing backflow.

[0033] Furthermore, a flow direction indicating arrow 2041 is provided on the operating handle 204; the setting of the flow direction indicating arrow 2041 enables the operator to intuitively understand the flow direction of flushing water in the valve housing 201, facilitates accurate operation, avoids operational errors, and improves the convenience and accuracy of operation.

[0034] Example 2:

[0035] The cam 502 is screwed to the cam 504 so that the cam 504 can be screwed to the cam 504. The cam 502 is screwed to the cam 504 so that the cam 504 can be screwed to the cam 504.

[0036] Example 3:

[0037] Based on Examples 1 and 2, please refer to 4. Filter assembly 7 includes a housing 701 fixed to the top of fixed plate 1. Housing 701 is connected to one end of connecting pipe 6. A filter element 702 is installed within housing 701. A cleaning assembly 703 is provided on the outside of filter element 702. An access panel 704 is screwed to the side of housing 701 away from outlet pipe 9. The provision of cleaning assembly 703 facilitates cleaning of filter element 702, maintains the filtering effect of filter element 702, and improves the filtration quality of the fluid. Access panel 704 is screwed for easy removal and installation, facilitating inspection and maintenance of filter element 702 and other components, ensuring the normal operation of filter assembly 7 and improving the reliability and stability of the entire bypass pipe system.

[0038] The existing filter element 702 cleaning method may be more complicated, and the filter element 702 needs to be disassembled for cleaning, which increases maintenance cost and time. To solve this problem, the cleaning assembly 703 includes a scraper ring 7031 sleeved on the outer wall of the filter element 702, an operating rod 7032 is fixedly connected to the scraper ring 7031, and a fixing block 7033 is sleeved at one end of the operating rod 7032. The fixing block 7033 is fixedly connected to the inner wall of the housing 701; the scraper ring 7031 is sleeved on the outer wall of the filter element 702, and the inspection plate 7033 is fixedly connected to the inspection plate 7033. After 704 is removed, by pulling the operating rod 7032 and driving the scraper ring 7031 to move left and right on the outer wall of the filter element 702, impurities attached to the filter element 702 are scraped off, and the filter element 702 is cleaned without removing the filter element 702, reducing maintenance time and cost, and the fixing block 7033 fixes the operating rod 7032 on the inner wall of the shell 701, ensuring the stability and reliability of the cleaning component 703, and improving the convenience and efficiency of cleaning the filter element 702.

[0039] The existing bypass pipe does not have a flow direction mark, and the operator may not be able to accurately judge the direction of water flow during installation and use, resulting in installation errors or improper use. To address this problem, flow direction marks are provided on the outer walls of the water inlet pipe 4 and the water outlet pipe 9; the setting of the flow direction mark enables the operator to clearly identify the water flow direction of the water inlet pipe 4 and the water outlet pipe 9, facilitates correct installation and use, avoids system failures caused by incorrect water flow direction, and improves the accuracy and convenience of installation and use.

[0040] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
