Description

Technical Field

[0001] This utility model relates to the technical field of water supply and drainage system renovation, and in particular to a digital pump set, pipe connectors and water supply and drainage assembly. Background Technology

[0002] Water supply and drainage systems generally consist of components such as hydraulic pumps, relief valves, directional valves, flow control valves, and pressure control valves. In engineering water supply and drainage systems, such as load-sensitive multi-way valve systems, there can be dozens of different types of components, increasing the system's complexity.

[0003] The root cause of the above problems lies in the fact that the design concept of existing water supply and drainage systems is based on the functional design of components, that is, to achieve corresponding functional control by designing or combining valves and pumps with different functions. This will cause the following problems: too many types of valves and pumps will lead to an increase in the system design, manufacturing and maintenance costs, and the outlets of several pumps are often very close together, which will cause several water flows to accumulate at each outlet and form turbulence, thereby increasing the pipeline pressure, and even causing water to flow back into the outlet pipe, resulting in changes in pipeline pressure and impact on the pipeline, which can easily cause a certain degree of damage to the pipeline. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0010] This utility model also discloses a pipe connector for connecting a digital pump set, including: a flexible joint assembly, including a first connecting flange connected to a water outlet, a second connecting flange disposed at a location away from the water outlet, and a steering component disposed between the first and second connecting flanges, the second connecting flange being connected to a distant water pipe; and a sealing assembly disposed on the first and second connecting flanges.

[0011] As a preferred embodiment of the pipe connector of this utility model, the turning component includes a first cylinder disposed on a first connecting flange, a second cylinder disposed on a second connecting flange, and a multi-directional adapter disposed between the first cylinder and the second cylinder. A first retaining ring is disposed at the end of the first cylinder away from the first connecting flange, and a second retaining ring is disposed at the end of the second cylinder away from the second connecting flange. The first retaining ring and the second retaining ring respectively form installation spaces at the ends of the first cylinder and the second cylinder.

[0012] As a preferred embodiment of the pipe connector of this utility model, the multi-directional adapter includes a first water-passing body disposed in the installation space on the first cylinder, a second water-passing body disposed in the installation space on the second cylinder, and a water-passing pipe communicating with the first water-passing body and the second water-passing body. Both the first water-passing body and the second water-passing body are provided with connecting holes, and both the first water-passing body and the second water-passing body are provided with sealing elements on their outer sides.

[0013] As a preferred embodiment of the pipe connector of this utility model, the sealing element includes a first flange and a second flange disposed on the outer side of the first water passage and the second water passage. The first flange and the second flange are arranged in a ring. The width ratio of the second flange to the width of the first flange is 1:1.8-1:2. The upper surface of the first flange is provided with a bent flange. After the second flange is bent, it is prevented from bending further by the bent flange to form a bending space.

[0014] This utility model also discloses a water supply and drainage assembly for connecting a digital pump group and a pipe connector, comprising: a main inlet pipe connected to several pump bodies; a hydraulic actuator disposed at the outlet end of the pump body, with an outlet pipe at the distal end of the hydraulic actuator; an outlet pipe with a non-obstruction connection component between the outlet pipe and several outlet pipes; and a control assembly electrically connected to the hydraulic actuator.

When the pump body stops, even if the water continues to flow, the reduced pressure at the outlet end reduces the pressure in the entire pipeline, thereby eliminating the "water hammer" phenomenon, reducing liquid backflow and pipeline pressure, and achieving an effect similar to a throttling valve. This results in cost savings and convenient installation. Attached Figure Description

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0031] Example 1

[0032] Reference Figure 1 This is the first embodiment of the present invention, which provides a digital pump set. In this embodiment, the pump set includes a pump set body 100, which is the main component of the entire digital pump set. A digital pump body 101 is selected and is installed in the pump room. In this embodiment, the pump set body 100 includes several pump bodies 101 that are directly connected to the water supply pipeline. The several pump bodies 101 are arranged in parallel with each other, so that each pump body 101 forms a single water pumping line.

[0033] Preferably, in order to arrange several pump bodies 101 in relation to each other, a main base plate is set inside the pump room. Several installation positions are pre-drilled on the base plate, and positioning holes are then drilled at the installation positions. Buffer washers are added, and the pump bodies 101 are then installed at the installation positions, ensuring that the end of each pump body 101 can be connected to the water supply pipeline. Finally, the pump bodies 101 are fixed with bolts.

[0034] Furthermore, each pump body 101 is provided with an inlet end 102 and an outlet end 103 at both ends. The inlet end 102 is mainly connected to the water supply pipe, while the outlet end 103 is mainly the outlet for pumping water outward.

[0035] In this embodiment, the water inlet 102 includes a water inlet pipe 102a connected to one end of the pump body 101 and a docking part 102b. The water outlet 103 includes a water outlet pipe 103a connected to the other end of the pump body 101 and a measuring element 103b. The measuring element 103b is mainly a sensor for detecting the pressure and flow rate inside the pump body 101, and is mainly used to monitor whether the pump body 101 is in normal working condition. The measuring element 103b is connected to the main control room through a circuit, so that the operator can directly observe it in the main control room.

[0036] Preferably, the mating part 102b includes a flange connecting ring 102b-2 connected to the water inlet 102a and a mating gasket disposed on the flange connecting ring 102b-2. The flange connecting ring 102b-2 can be used to position the connection position of the water inlet 102a, while the mating gasket plays a buffering role after installation.

[0037] Furthermore, a control component 104 is provided on the pump body 101. In this embodiment, the control component 104 includes a control motor 104a provided on each pump body 101. The control motor 104a controls the start and stop of the pump body 101. The control motor 104a is also externally connected to the main control room for remote control by the operator.

[0038] Furthermore, an external control unit 104 is provided on the pump body 101. In this embodiment, the external control unit 104 includes an external control box connected to the pump body 101. The external control box is equipped with hardware structures such as a power supply module, a start / stop control module, and wiring ports. The external control box is also connected to the main control room, thereby facilitating remote control of the pump by the operator.

[0039] The specific implementation principle of this embodiment is as follows: When installing the pump body 101 and the water supply pipeline, the pump body 101 and the water supply pipeline are directly connected through a flange. Compared with the prior art, we do not install throttling components such as throttling valves. Instead, the outlet end 103 of the pump body 101 is connected to a flow-free drainage system, which reduces the liquid pressure at each outlet of the pump body 101. When the pump body 101 stops, even if the water continues to flow, the reduced pressure at the outlet end 103 reduces the pressure in the entire pipeline, thereby eliminating the "water hammer" phenomenon, reducing liquid backflow and pipeline pressure, and achieving an effect similar to a throttling valve. This results in cost savings and convenient installation.

[0040] Example 2

[0041] Reference Figure 2-5 This embodiment differs from the previous embodiment in that it also discloses a pipe connector for connecting a digital pump set. The pipe connector is mainly used to connect the pump body 101 with the water supply pipe and the water outlet pipe 302. It is set at the water outlet 103 and the water inlet 102. In this embodiment, only the case of connecting at the water outlet 103 is described. If it is connected at the water inlet 102, the structure and connection method are the same as the connection at the water outlet 103.

[0042] The pipe connector includes a flexible joint assembly 200. In this embodiment, the flexible joint assembly 200 includes a first connecting flange 201 connected to the water outlet 103a, a second connecting flange 202 disposed away from the water outlet 103a, and a turning component 203 disposed between the first connecting flange 201 and the second connecting flange 202. The first connecting flange 201 is fixedly connected to the water outlet 103a. In this embodiment, the first connecting flange 201 and the water outlet 103a are fixedly connected by bolts. In order to ensure sealing, a sealing component is also provided. The sealing component is disposed on the first connecting flange 201 and the second connecting flange 202. The sealing component is a rubber gasket disposed between the first connecting flange 201 and the water outlet 103a.

[0043] Furthermore, the second connecting flange 202 is connected to the water pipe at the far end. The size of the second connecting flange 202 is the same as that of the first connecting flange 201. The steering component 203 mainly connects the first connecting flange 201 and the second connecting flange 202. It is worth noting that due to the different installation positions, the first connecting flange 201 and the second connecting flange 202 are not necessarily directly opposite each other, and thus a flexible connection is achieved through the steering component 203.

[0044] In this embodiment, the steering component 203 includes a first cylindrical body 203a disposed on the first connecting flange 201, a second cylindrical body 203b disposed on the second connecting flange 202, and a multi-directional adapter 204 disposed between the first cylindrical body 203a and the second cylindrical body 203b. The first cylindrical body 203a is welded and fixed to the first connecting flange 201, and the second cylindrical body 203b is welded and fixed to the second connecting flange 202 or is integrally molded to ensure the sealing between the two and the overall strength.

[0045] Furthermore, a first retaining ring 203c is provided at the end of the first cylinder 203a away from the first connecting flange 201, and a second retaining ring 203d is provided at the end of the second cylinder 203b away from the second connecting flange 202. Both the first retaining ring 203c and the second retaining ring 203d are open at both ends, and the opening degree at the end away from the first cylinder 203a is smaller than the opening degree at the end closer to the first cylinder 203a. The opening degree of the second retaining ring 203d is the same as that of the first retaining ring 203c, so that the first retaining ring 203c and the second retaining ring 203d form installation spaces at the ends of the first cylinder 203a and the second cylinder 203b, respectively.

[0046] In this embodiment, the multi-directional adapter 204 includes a first water-passing body 204a disposed in the mounting space on the first cylinder 203a, a second water-passing body 204b disposed in the mounting space on the second cylinder 203b, and a water-passing pipe 204c communicating between the first water-passing body 204a and the second water-passing body 204b. In this embodiment, the first water-passing body 204a and the second water-passing body 204b are both hollow spheres, and the overall material is stainless steel or other materials with water erosion resistance and impact resistance. The diameter of the sphere is smaller than the front opening size of the first retaining ring 203c and the second retaining ring 203d, so that the first water-passing body 204a and the second water-passing body 204b can rotate freely and will not fall out of the mounting space.

[0047] Furthermore, several connecting holes 204d are provided on both the first water passage body 204a and the second water passage body 204b, and the connecting holes 204d correspond to the first cylinder body 203a or the second cylinder body 203b. The water passage pipe 204c connects the first water passage body 204a and the second water passage body 204b by welding. Water flows into the first water passage body 204a through the first cylinder body 203a, then flows into the second water passage body 204b through the water passage pipe 204c, and then flows out from the connecting holes 204d on the second water passage body 204b and into the second cylinder body 203b, thus flowing towards the water outlet pipe 302.

[0048] Because of the unique spherical design of the first water passage 204a and the second water passage 204b, the first water passage 204a and the second water passage 204b can rotate within the first retaining ring 203c and the second retaining ring 203d. When the first connecting flange 201 and the second connecting flange 202 are not aligned, the operator can adjust the first water passage 204a or the second water passage 204b so that the first cylinder 203a and the second cylinder 203b are no longer aligned, but are aligned with the first connecting flange 201 and the second connecting flange 202 respectively, thereby achieving the effect of a soft connection.

[0049] Preferably, a sealing element 205 is provided on the outside of both the first water passage 204a and the second water passage 204b. The sealing element 205 is set in the same way at the first water passage 204a and the second water passage 204b. Here, only the specific structure of the sealing element 205 at the first water passage 204a is described. The structure of the sealing element 205 at the second water passage 204b is the same.

[0050] In this embodiment, the sealing element 205 includes a first flange 205a and a second flange 205b disposed on the outside of the first water-passing body 204a, and the first flange 205a and the second flange 205b are arranged in a ring.

[0051] Furthermore, there is a certain distance difference between the first flange 205a and the second flange 205b. The shapes of the first flange 205a and the second flange 205b are both annular when not subjected to external force. When the operator installs the first water passage 204a, the first water passage 204a will move the first flange 205a and the second flange 205b, flipping the first flange 205a and the second flange 205b away from the first cylinder 203a.

[0052] Preferably, the width ratio of the second flange 205b to the width of the first flange 205a is 1:1.8-1:2. Therefore, when the first water-passing body 204a is installed, the flipping area of ​​the first flange 205a is larger than that of the second flange 205b, so that the first flange 205a has a larger relative area to fit against the outer wall of the first water-passing body 204a, thereby increasing the waterproof capability.

[0053] Furthermore, a bent flange 205c is provided on the upper surface of the first flange 205a, with the bent flange 205c facing upward. When the second flange 205b is bent by the inserted first water passage 204a, it will be blocked by the bent flange 205c and guided by the bent flange 205c to undergo further bending, thereby forming a bending space.

[0054] Operation process: When water flows through the first flange 205a and the second flange 205b, both flanges 205a and 205b are bent. When the second flange 205b bends, it cooperates with the bending flange 205c and, guided by the bending flange 205c, bends back, thus forming a water storage space. At this time, the water flow is initially blocked by the first flange 205a. After the first flange 205a's obstruction becomes ineffective, the water flow breaks through the first flange 205a and enters the water storage space through the permeable holes. Because of the structural design of the permeable holes, the amount of water flowing out of the water storage space is less than the amount of water entering the water storage space, causing the water to accumulate in the water storage space. When a certain amount is accumulated, the water will press the second flange 205b, pushing the free end of the second flange 205b outward, causing the free end of the second flange 205b to bend away from the water storage space. As a result, the second flange 205b will increase its area and fit against the first water passage body 204a. At this time, the second flange 205b will continue to form a barrier, hindering the spread of water and thus ensuring the sealing effect.

[0055] Example 3

[0056] Reference Figure 6-8 This embodiment differs from the previous embodiment in that: the present invention also discloses a water supply and drainage assembly for connecting a digital pump group and a pipe connector, including a main water inlet pipe 300, which is connected to several pump bodies 101. The main water inlet pipe 300 is mainly the main water supply pipeline and plays the role of water flow.

[0057] Furthermore, it also includes a hydraulic actuator 301, which is installed at the outlet end 103 of the pump body 101. The hydraulic actuator 301 has an outlet pipe 301a at its far end. The hydraulic actuator 301 itself is a pipeline connected to the outlet end 103, and a control module capable of control is installed on the pipeline. The hydraulic actuator 301 is wirelessly controlled by the system to adjust the valve opening to regulate the flow rate, and the hydraulic actuator 301 is connected to the second connecting flange 202.

[0058] Furthermore, it also includes a water outlet pipe 302, and a non-obstruction connection component 304 is provided between the water outlet pipe 302 and several water outlet pipes 301a. The non-obstruction connection component 304 is mainly used to eliminate the pressure at each water outlet end 103 of the pump body 101 and reduce the occurrence of "water hammer".

[0059] Furthermore, it also includes a control assembly 303, which is electrically connected to the hydraulic actuator 301.

[0060] Furthermore, in this embodiment, the unobstructed connection component 304 includes a connecting pipe body 304a connected to the water outlet pipe 302, an extension drain pipe body 304b disposed within the connecting pipe body 304a, and a connecting water inlet 304c opened on the connecting pipe body 304a. The connecting pipe body 304a is welded or integrally formed with the water outlet pipe 302 to ensure sealing. The end of the connecting pipe body 304a is sealed, allowing only the extension drain pipe body 304b to connect. The extension drain pipe body 304b extends into the connecting pipe body 304a, so that the position of the pipe opening of the extension drain pipe body 304b is far away from the position of the connecting water inlet 304c.

[0061] Preferably, the extended drain pipe 304b is connected to one of the outlet pipes 301a, and the connecting port 304c is connected to the other outlet pipe 301a. The connecting port 304c is located on the side wall of the connecting pipe 304a, while the extended drain pipe 304b extends along the length of the connecting pipe 304a, thereby causing the position of the connecting port 304c to be offset from the position of the pipe opening of the extended drain pipe 304b.

[0062] The specific implementation principle of this embodiment is as follows: the outlet of the extended drain pipe 304b is deeper into the connecting pipe 304a, while the connecting water outlet 304c is closer to the end of the connecting pipe 304a. This arrangement prevents the water flowing out from the extended drain pipe 304b and the water flowing out from the connecting water outlet 304c from directly merging. The point where the two water flows meet is extended into the connecting pipe 304a, thereby reducing turbulence caused by the direct convergence of the two water flows. Consequently, the water flow resistance and pressure are reduced, and the backflow of water into the outlet pipe 301a is also reduced, thereby reducing the pipe pressure. Thus, the effect of a throttle valve can be achieved without the need to install a throttle valve.

[0063] Preferably, a main guide vane 305 is provided on the connecting inlet 304c, and a secondary guide vane 306 is provided on the extended drain pipe body 304b near the connecting inlet 304c. Both the secondary guide vane 306 and the main guide vane 305 are thin sheets, and both the main guide vane 305 and the secondary guide vane 306 face the same direction. This guides the water flowing out of the connecting inlet 304c to flow along the length of the connecting pipe body 304a, thereby further reducing turbulence and water pressure.
