Description

Technical Field

[0001] The utility model relates to the technical field of secondary water supply, in particular to a cleaning joint and a self-cleaning flow stabilizing tank. Background Technique

[0002] At present, after the flow stabilizing tank works for a period of time, due to calcium ions, magnesium ions, etc. existing in the water quality of the connected pipe network in the tank body, scale is generated on the side head surface and the bottom of the tank body, resulting in the output water quality being affected by the scale. Moreover, the scale adheres to the stainless steel plate surface, which is easy to corrode and rust, and in serious cases, water leakage problems will occur. Secondly, when sand, stones, etc. in the pipe network pass through the Y-shaped filter, they are not completely filtered. When they reach the booster pump through the flow stabilizing tank, it will cause serious harm to the pump body. In the design and development of the non-negative pressure flow stabilizing tank, the main cleaning methods for the non-negative pressure flow stabilizing tank on the market are: manual regular brushing, chemical scale remover cleaning, and motor-driven brush cleaning, etc. However, these methods are either troublesome to operate and cannot meet the requirements of energy conservation and emission reduction; or they cause secondary pollution to drinking water and pose a hazard to human health.

[0003] Therefore, the self-cleaning function of the non-negative pressure flow stabilizing tank is particularly important. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cleaning joint and a self-cleaning flow stabilizing tank, which are used for boosting the water flow, filtering impurities in the water, and can be used to prevent scale from being generated in the flow stabilizing tank and damaging the flow stabilizing tank, and improving the water quality of the conveyed water flow.

[0007] A main pipe body, the main pipe body includes a first branch pipe and a second branch pipe, the first branch pipe is communicated with the second branch pipe, the first branch pipe and the second branch pipe are bent, and the included angle between the bent first branch pipe and the second branch pipe is 60°-120°;

[0008] A flushing head, the flushing head is arranged at one end of the main pipe body, one end of the flushing head is circular and the other end is flat, and a plurality of flushing ports are uniformly arranged inside the flushing head;

[0009] A connecting piece, the connecting piece is arranged at the other end of the main pipe body for installing and fixing the main pipe body.

[0010] Preferably, the ratio of the sum of the water outlet caliber areas of the plurality of flushing ports to the sum of the water inlet caliber areas of the main pipe body is 1:2-2:3.

[0011] Preferably, the first branch pipe and the second branch pipe are made by an integral molding method; and / or,

[0012] The flushing head is detachably mounted at one end of the second branch pipe; and / or,

[0013] The connecting member is fixedly arranged at one end of the first branch pipe.

[0014] A self-cleaning flow stabilizing tank, comprising:

[0015] A tank body, an inlet interface is arranged at a position near one end at the top of the tank body, and a drain interface is arranged at the bottom of the tank body;

[0016] Two end closures, the end closures are spherical in shape and are respectively arranged at both ends of the tank body;

[0017] The above-mentioned cleaning joint, the cleaning joint is installed inside the tank body at a position corresponding to the inlet interface through a connecting member, and the flushing head faces the end closure to wash the inner wall of the end closure and generate a water flow in the tank body that flows from one end closure through the bottom wall of the tank body to the other end closure, so as to wash the other end closure.

[0018] Preferably, an installation part is arranged inside the tank body at the inlet interface for cooperating with the connecting member to fix the main pipe body.

[0019] Preferably, the installation part is an annular boss arranged around the inlet interface, the connecting member is a flange, and studs for passing through through holes of the flange are annularly arranged on the annular boss to cooperate with nuts to fix the flange.

[0020] Preferably, after the cleaning joint is installed inside the tank body, the flushing head faces the end closure.

[0021] Preferably, after the cleaning joint is installed inside the tank body, the second branch pipe is arranged vertically or obliquely downward at an angle of 0° to 30° with the axis direction of the tank body.

[0022] Preferably, the self-cleaning flow stabilizing tank further includes an auxiliary joint for externally connecting a negative pressure suppressor to prevent negative pressure from being generated inside the tank body; and / or,

[0023] The auxiliary joint is located at a position of the tank body near the other end closure.

[0024] Preferably, the self-cleaning flow stabilizing tank further includes support members, and at least two support members are respectively arranged at positions near both ends at the bottom of the tank body.

[0025] Compared with the prior art, the beneficial effects of the present utility model at least include:

[0026] When in use, this cleaning connector can utilize the difference in the cross-sectional area between the water inlet side and the flushing port to generate a relatively high water flow velocity on the flushing head side without using external pressurization equipment, achieving multiple functions. Moreover, the flushing port with rectangular square holes can filter impurities such as sand and stones in the water flow, improving the water quality to a certain extent and having better practicability.

[0027] Furthermore, during the long-term use of the self-cleaning steady flow tank with this cleaning connector, when the water in the pipe network enters through the cleaning connector, it pressurizes the water flow, significantly reducing the laminar flow area of the water flow fluid state in the tank and greatly reducing the dominant field where water scale can form. The second branch pipe of the cleaning connector shoots vertically or obliquely downward at an angle of ° to ° with the axis direction of the tank body towards the head, forming a reverse flow field at the optimal angle in the tank body, reducing the energy loss of the water entering the tank. Thus, it can solve the problem that water scale formed by calcium ions, magnesium ions, etc. in the water quality flowing through the tank body adheres to the inner wall of the stainless steel head and the bottom of the tank body, avoiding problems such as electrochemical corrosion, rust on the tank body affecting the water quality of the outlet, and water leakage at the weld between the head and the tank body. The entire process uses physical pressurization in the cleaning connector to wash the head, without the need to externally connect pressurization equipment such as a booster pump for pressurized flushing, which is more energy-saving and environmentally friendly. At the same time, since impurities such as sand and stones in the upstream water inlet pipe network of the tank body may not be completely filtered when passing through components such as the Y-shaped filter, when they are discharged from the tank body and flow through subsequent components such as the booster pump, they will affect the normal operation of these components. However, after using the steady flow tank equipped with the cleaning connector, the main pipe body and the flushing port with a rectangular cross-sectional shape can filter large particle impurities such as sand and stones, achieving the effect of improving water quality. And when there is no water inlet, the sand and stones automatically slide into the bottom of the second branch pipe, and it is not easy to block the flushing port, enabling the cleaning connector to maintain a long service life.

[0039] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this utility model will be more complete and comprehensive, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their repetitive description will be omitted.

[0040] In this utility model, the words expressing position and direction are described by taking the accompanying drawings as examples, but can be changed according to needs, and all changes made are included in the protection scope of this utility model.

[0041] Referring to Figures 1 to 3 , this application provides a cleaning joint, including: a main pipe body 1, a flushing head 2 and a connecting piece 3.

[0042] Specifically, the main pipe body 1 includes a first branch pipe 101 and a second branch pipe 102. The first branch pipe 101 is communicated with the second branch pipe 102. The first branch pipe 101 and the second branch pipe 102 are bent, and the included angle between the bent first branch pipe 101 and the second branch pipe 102 is 90° - 120°; when the included angle between the first branch pipe 101 and the second branch pipe 102 is 90°, the first branch pipe 101 is perpendicular to the second branch pipe 102. At this time, the main pipe body 1 is a right-angled L-shaped elbow; when the included angle between the first branch pipe 101 and the second branch pipe 102 is 120°, the first branch pipe 101 and the second branch pipe 102 form an obtuse angle. At this time, the main pipe body 1 is an obtuse-angled elbow. Among them, the first branch pipe 101 and the second branch pipe 102 are preferably made by an integral molding method. Specifically, the first branch pipe 101 and the second branch pipe 102 can be made by methods including but not limited to injection molding or casting, and are not uniquely limited herein.

[0043] The flushing head 2 is arranged at one end of the main pipe body 1. One end of the flushing head 2 is circular and the other end is flat. A number of flushing ports 201 are evenly arranged inside the flushing head 2. Specifically, the flushing head 2 is preferably of a solid structure. The cross-sectional structure of the flushing port 201 is preferably a rectangular square hole structure, and the flushing ports 201 are evenly arranged along the flat end of the flushing head 2. The ratio of the sum of the water outlet diameters of the several flushing ports 201 to the sum of the water inlet diameters of the main pipe body 1 is 1:2 to 2:3, so that water enters from one end of the main pipe body 1 and is discharged through the flushing ports 201. Since the water inflow of the main pipe body 1 is greater than the water discharge of the flushing ports 201, at this time, by using the difference between the water inflow and outflow at both ends of the main pipe body 1, a relatively large water pressure will be generated inside the main pipe body 1, which can increase the drainage flow rate of the flushing ports 201 without using external pressurizing equipment such as a booster pump. At the same time, the flushing ports 201 arranged in a rectangular square hole structure can filter out impurities such as gravel and stones in the water, and to a certain extent, can purify and filter the water quality and improve the water quality.

[0044] As a preferred method, the flushing head 2 is detachably installed at one end of the second branch pipe 102. Specifically, for example, an existing structure such as a threaded sleeve (not shown) can be arranged at the circular end of the flushing head 2, and an external thread (not shown) adapted to the threaded sleeve is provided on the outer wall of the corresponding end of the second branch pipe 102, so that the flushing head 2 can be installed on the second branch pipe 102 by a threaded method, so that in actual application, the flushing head 2 or the main pipe body 1 can be replaced according to the situation. At the same time, the gravel, stones and other impurities filtered inside the main pipe body 1 can also be cleaned by removing the flushing head 2.

[0045] It should be noted that the flushing head 2 and the second branch pipe 102 can also be connected in a fixed manner. However, in this case, when any structure of the main pipe body 1 or the flushing head 2 is damaged, the entire cleaning joint needs to be replaced. And when it is necessary to clean the gravel, stones and other impurities filtered inside the main pipe body 1, the main pipe body 1 needs to be removed from the tank body 4 as a whole, and the gravel, stones and other impurities are poured out from one end of the first branch pipe 101.

[0046] The connecting piece 3 is arranged at the other end of the main pipe body 1 for installing and fixing the main pipe body 1. Among them, the connecting piece 3 is preferably fixedly arranged at one end of the first branch pipe 101. More preferably, the connecting piece 3 and the first branch pipe 101 can be made by an integral molding method such as injection molding or casting, so as to improve the strength of the entire cleaning joint and extend its service life.

[0047] Thus, when in use, the cleaning joint can, without using an external pressurization device, utilize the difference in the cross-sectional areas of the water inlet side and the flushing port 201 to generate a relatively high water flow velocity on one side of the flushing head 2, achieving multiple functions. Moreover, by adopting a rectangular-shaped flushing port 201 with square holes, impurities such as sand and stones in the water flow can be filtered, improving the water quality to a certain extent and having better practicality.

[0048] Referring to Figure 4 and Figure 5 , the present application also provides a self-cleaning flow-stabilizing tank, comprising: a tank body 4, a head 403, and a cleaning joint. Among them, the tank body 4 is preferably a cylindrical structure.

[0049] Specifically, a water inlet interface 401 is provided at a position near one end of the top of the tank body 4, and a drain interface 402 is provided at the bottom of the tank body 4; among them, connection flanges are provided at the ends of the water inlet interface 401 and the drain interface 402 away from the tank body 4 for connecting to external devices so that water can be transported into the tank body 4.

[0050] Furthermore, after the cleaning joint is installed inside the tank body 4, the flushing head 2 faces the head 403. Preferably, after the cleaning joint is installed inside the tank body 4, the second branch pipe 102 forms an angle of 0° to 30° with the axis direction of the tank body 4 and is arranged to face the head 403 in a vertical or inclined downward posture. Among them, when the angle between the first branch pipe 101 and the second branch pipe 102 is 90°, the second branch pipe 102 forms an angle of 0° with the axis direction of the tank body 4, that is, the second branch pipe 102 coincides with the axis of the tank body 4. At this time, the water discharged from the flushing port 201 of the flushing head 2 shoots directly at the head 403 and impacts one side of the head 403; when the angle between the first branch pipe 101 and the second branch pipe 102 is greater than 90° and less than or equal to 120°, the second branch pipe 102 is arranged in a direction forming an angle greater than 0° and less than or equal to 30° with the axis direction of the tank body 4. At this time, the water discharged from the flushing port 201 of the flushing head 2 shoots obliquely downward and impacts one side of the head 403. Thus, the water in the pipe network can enter the main pipe body 1 through the water inlet interface 401, the first branch pipe 101, and the second branch pipe 102. During this process, the water flow can be pressurized. The water flow discharged from the flushing port 201 can perform a high-pressure flushing of a certain intensity on the surface of the head 403, and the water flow can flow along one side of the head 403 in the tank body 4 through the bottom wall of the tank body 4 and then reach the head 403 on the other side, resulting in a significant reduction in the laminar flow region of the fluid state inside the tank body 4, greatly reducing the dominant field for forming scale inside the tank body 4, making it difficult to form scale, enabling the tank body 4 to have a certain self-cleaning effect, thereby avoiding the occurrence of electrochemical corrosion due to scale adhering to the inner walls of the tank body 4 and the head 403, causing the tank body 4 to rust and affecting the water quality of the transported water flow. At the same time, it can also avoid problems such as water leakage at the connection between the head 403 and the tank body 4.

[0051] There are two heads 403, which are spherical in shape and are respectively arranged at both ends of the tank body 4; preferably, the heads 403 on both sides are installed at both ends of the tank body 4 by welding. Of course, they can also be made by integral molding, and there is no unique limitation here.

[0052] The cleaning joint is installed inside the tank body 4 at a position corresponding to the water inlet interface 401 through the connecting piece 3. The water flow output by the flushing head 2 towards the head 403 shoots towards the inner wall of the head 403 and can generate a water flow flowing from one head 403 through the bottom wall of the tank body 4 to the other head 403 inside the tank body 4, so as to form a fluid flow field inside the tank body 4 and reduce the formation of scale inside it.

[0053] As a preferred method, an installation part is provided inside the tank body 4 at the water inlet interface 401 for cooperating with the connecting piece 3 to fix the main pipe body 1. Among them, the installation part is preferably an annular boss arranged around the water inlet interface 401, and the connecting piece 3 is a flange. The flange is preferably the same size and shape as the annular boss, so that the outer contour edges of the two can coincide during assembly. The annular boss is annularly provided with studs for passing through the through holes of the flange to fix the flange with a matching nut. Specifically, during installation, the studs are aligned with the through holes of the flange and passed through, and the main pipe body 1 is installed inside the tank body 4 by the cooperation of the nut and the stud. Subsequently, when it is necessary to clean sundries such as gravel and stones filtered inside the main pipe body 1, the main pipe body 1 can be removed and the internal impurities can be poured out.

[0054] Therefore, during the long-term use of the self-cleaning flow-stabilizing tank with a cleaning joint, when the water inlet from the pipe network passes through the cleaning joint, the water flow is pressurized, significantly reducing the laminar flow area of the water flow fluid state in the tank body 4, greatly reducing the dominant field for scale formation, and the second branch pipe 102 of the cleaning joint shoots vertically or obliquely downward at an angle of 0° to 30° with the axis direction of the tank body 4 towards the head 403, forming a reverse flow field at the optimal angle in the tank body 4, reducing the energy loss of the water inlet to the tank body 4, thereby being able to solve the problem that scale formed by calcium ions, magnesium ions, etc. in the water quality flowing through the tank body 4 adheres to the inner wall of the stainless steel head 403 and the bottom of the tank body 4, avoiding problems such as electrochemical corrosion, rust on the tank body 4 affecting the water quality of the outlet water, and water leakage at the weld joint between the head 403 and the tank body 4. The entire process uses physical pressure increase in the cleaning joint to wash the head 403, without the need to externally connect a booster pump or other pressurizing equipment for pressurized flushing, being more energy-saving and environmentally friendly. At the same time, since impurities such as gravel and stones in the upstream water supply pipe network of the tank body 4 may not be completely filtered when passing through components such as a Y-shaped filter and will affect the normal operation of components such as the booster pump when passing through the tank body 4 and flowing through subsequent components such as the booster pump, after using a flow-stabilizing tank equipped with a cleaning joint, the main pipe body 1 and the flushing port 201 with a rectangular cross-sectional shape can filter large-particle gravel, stones and other impurities, achieving the effect of improving water quality, and when there is no water inlet, the gravel and stones automatically slide into the bottom of the second branch pipe 102, not easily causing blockage of the flushing port 201, and being able to keep the cleaning joint in service for a long time.

[0055] In a specific embodiment, the self-cleaning flow-stabilizing tank further includes an auxiliary joint 404 for externally connecting a negative pressure suppressor to prevent negative pressure from being generated inside the tank body 4. The auxiliary joint 404 is located at a position of the tank body 4 close to the other head 403 to avoid the negative pressure inside the tank body 4 affecting the water supply to downstream users.

[0056] In a specific embodiment, the self-cleaning flow-stabilizing tank further includes a support member 5. There are at least two support members 5, which are respectively arranged at positions close to both ends of the bottom of the tank body 4; specifically, preferably two support members 5 are provided and are respectively arranged at positions close to both ends of the bottom of the tank body 4. The structure of a single support member 5 is a support leg with a square bottom plate, and waist-shaped holes are symmetrically arranged at both ends of the square bottom plate to install the flow-stabilizing tank on a base or the ground through components such as screws or expansion screws, so as to keep the flow-stabilizing tank stable.

[0057] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Without departing from the principle and purpose of the present utility model, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the utility model, and all such changes should fall within the protection scope of the claims of the present utility model.
