Description

Technical Field

[0001] This utility model relates to the field of precision control technology, and more specifically, to a diversion device. Background Technology

[0002] When cooling equipment, there are usually several temperature control units. In order to ensure the temperature control requirements of each temperature control unit and to maximize the effectiveness of the large temperature control equipment, the constant temperature fluid produced by the large temperature control equipment needs to be distributed to each temperature control unit through a flow distribution component. In the existing technology, the constant temperature fluid is distributed using a flow distribution component. The existing flow distribution component usually uses a combination of a flow distributor and a flow collector. The flow distributor distributes the constant temperature fluid produced by the large temperature control equipment into the temperature control unit, and the flow collector collects the high temperature fluid returning from the temperature control unit and returns it to the large temperature control equipment.

[0003] However, in the process of implementing this technology, the applicant discovered that the prior art has at least the following problems:

[0004] When the temperature control unit is under maintenance or blocked, the thermostatic fluid will continue to accumulate in the main channel of the distributor, increasing the pressure at the distributor and preventing the fluid from flowing back to the main temperature control equipment, resulting in poor overall system circulation and affecting system stability.

[0005] In summary, how to solve the problem of increased pressure at the distributor and inability of fluid to flow back to the main temperature control equipment when the temperature control unit is under maintenance or blocked is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a flow divider to solve the problem that when the temperature control unit is under maintenance or blocked, the pressure at the flow divider increases and the fluid cannot flow back to the main temperature control unit.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A shunt device, comprising:

[0009] At least two diversity stream components, each comprising an interconnected main channel and several branch channels;

[0010] In this configuration, a bypass channel is provided between the main channels of different diversity stream components, and a bypass regulating valve is provided in the bypass channel.

[0011] Preferably, the main channel of the diversity stream component is connected to the corresponding main interface, and the branch channel of the diversity stream component is connected to the corresponding branch interface;

[0012] The branch channel of the diversity flow component or the passage connected to the branch interface is provided with a branch regulating valve for regulating the fluid flow rate in the corresponding branch channel;

[0013] A bypass channel is provided between the main channels of different diversity flow components, and a bypass regulating valve is provided in the bypass channel.

[0015] And / or, the branch channel of the diversity stream component or the passage connecting it to the branch interface is provided with a branch valve.

[0016] Preferably, the main channel of the diversity stream component or the path connecting it to the main interface is equipped with a voltage regulator component.

[0017] Preferably, the main channel of the diversity stream component or the path connecting it to the main interface is provided with a main flow statistics component;

[0018] And / or, the branch channel of the diversity flow component or the path connected to the branch interface is provided with a branch flow statistics component.

[0019] Preferably, a pressure monitoring component is provided at the main interface for monitoring the fluid pressure within the main interface.

[0020] Preferably, an exhaust assembly is provided at the high position of the diversity flow assembly;

[0021] And / or, a drainage component is provided at the lower position of the diversity flow component.

[0022] Preferably, the diversity stream component includes a splitter and a collector;

[0023] The main interface includes a main water inlet interface and a main water return interface;

[0024] The branch interface includes a branch water inlet interface and a branch water return interface;

[0025] The main channel of the diverter is connected to the main water inlet, and the branch channel of the diverter is connected to the branch water inlet.

[0026] The main channel of the collector is connected to the main return water interface, and the branch channel of the collector is connected to the branch return water interface.

[0027] Preferably, the distribution device further includes a cabinet, the distribution component is arranged inside the cabinet, and both the main interface and the branch interface extend to the outside of the cabinet;

[0031] The diversion device provided by this utility model has at least the following advantages compared with the prior art:

[0032] By setting a bypass channel between the main channels of different manifold components, the thermostatic fluid in the manifold component, which acts as a distributor, can flow back directly to the manifold component, which acts as a collector, without passing through the branch channel. This satisfies the need for thermostatic fluid return when the temperature control unit is under maintenance or blocked, avoids the accumulation of thermostatic fluid at the distributor causing an increase in distributor pressure, and ensures that the fluid can circulate within the system, thus ensuring system stability.

[0033] Furthermore, when the number of temperature control units is greater than the number of branch channels of the flow distribution components, multiple flow distribution components can be connected through bypass channels, so that all of the multiple flow distribution components can be used as flow distributors or flow collectors after being connected in parallel, thereby increasing the number of branch channels used for flow distribution or flow collection, and preventing some temperature control units from being unable to obtain constant temperature fluid.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] The core of this utility model is to provide a flow distribution device, which has the ability to individually adjust the flow of each branch channel by connecting a branch regulating valve in series between the branch channel and the branch interface of the flow distribution component, thereby realizing the individual adjustment of the temperature control effect of each temperature control unit.

[0050] Please refer to Figure 1 , Figure 2 and Figure 3 A shunt device, comprising:

[0051] At least two diversity stream components 4, each diversity stream component 4 including an interconnected main channel and several branch channels;

[0052] Among them, a bypass channel 5 is provided between the main channels of different diversity flow components 4, and a bypass regulating valve 52 is provided in the bypass channel 5.

[0053] like Figure 1 , Figure 2 and Figure 3As shown, the diversion device includes at least two sets of diversion and flow-dividing components 4. A bypass channel 5 is provided between the main channels of the two sets of diversion and flow-dividing components 4. When the temperature control unit is under maintenance or blocked, the total amount of fluid flowing through the temperature control unit decreases. At this time, the pressure in the upstream diversion and flow-dividing component 4 increases. Therefore, the bypass channel 5 is opened at this time, so that the main channels of the two sets of diversion and flow-dividing components 4 are connected, and the fluid in the high-pressure diversion and flow-dividing component 4 flows back directly to the low-pressure diversion and flow-dividing component 4 through the bypass channel 5. That is, the fluid flows back directly without passing through the temperature control unit, thereby ensuring the stability of the system pressure and ensuring smooth fluid flow.

[0054] Furthermore, when the number of temperature control units is greater than the branch channels of a single flow distribution component 4 in the flow distribution device, a bypass channel 5 is used to connect the main channels of multiple flow distribution components 4, that is, multiple flow distribution components 4 are connected in parallel, increasing the number of branch channels used for flow distribution or flow distribution, so as to meet the simultaneous temperature control of more temperature control units.

[0055] In some embodiments, the main channel of the diversity stream component 4 is connected to the corresponding main interface 2, and the branch channel of the diversity stream component 4 is connected to the corresponding branch interface 3.

[0056] The branch channel of the flow distribution assembly 4 or the passage connecting it to the branch interface 3 is provided with a branch regulating valve 35 for regulating the fluid flow rate in the corresponding branch channel.

[0057] A bypass channel 5 is provided to connect the main channels of different diversity flow components 4, and a bypass regulating valve 52 is provided in the bypass channel.

[0058] like Figure 1 , Figure 2 and Figure 3 As shown, the main channel of the diversity stream component 4 is connected to the main interface 2, the branch channel of the diversity stream component 4 is connected to the branch interface 3, and a branch regulating valve 35 is connected in series between each branch channel and the branch interface 3.

[0059] In use, the main interface 2 is connected to the large temperature control device, and the branch interface 3 is connected to each temperature control unit. The constant temperature fluid is diverted to each temperature control unit through the manifold component 4, or the fluid from each constant temperature unit is collected by the manifold component 4 and then flows to the large temperature control device. During this process, by adjusting the branch regulating valve 35 and changing the diameter of the branch regulating valve 35, the flow rate of the corresponding branch channel can be changed, thereby changing the flow rate or velocity of the corresponding temperature control unit and thus changing the temperature control effect of the corresponding temperature control unit.

[0060] In some embodiments, two diversion devices are used in combination. One diversion device's diversion and collection component 4 is used as a diverter 41 to separate the constant temperature fluid generated by the large temperature control device to the temperature control unit for temperature control, while the other diversion device's diversion and collection component 4 is used as a collector 42 to collect the return water from the temperature control unit and return it to the large temperature control device, thereby realizing fluid circulation.

[0061] In some embodiments, two flow splitting and combining components 4 are integrated in a single flow splitting device, serving as a flow splitter 41 and a flow collector 42 respectively. A branch regulating valve 35 is provided between the branch channel and the branch interface 3 of the flow splitter 41 and / or the flow collector 42, which can realize fluid circulation and control the flow rate of a single branch channel, thereby controlling the temperature control effect of a single temperature control unit.

[0062] Among them, the branch regulating valve 35 is preferably a needle valve, which has a more precise flow regulation capability.

[0063] When the two flow-collecting components 4 are used as a splitter 41 and a collector 42 respectively, when the total flow rate in the branch channel decreases, the pressure in the main channel of the splitter 41 will increase. By opening the bypass regulating valve 52, some of the fluid in the splitter 41 can flow directly to the main channel of the collector 42 through the bypass channel 5, thereby reducing the pressure in the main channel of the splitter 41 and ensuring the stability of the system pressure.

[0064] When neither the branch interface 3 of the distributor 41 nor the collector 42 is connected to a pipe, the bypass channel 5 can be directly connected. In this case, the distributor 41 and the collector 42 can form a fluid circulation through the bypass channel 5, thus preventing the constant temperature fluid from accumulating in the distributor 41 or the collector 42.

[0065] Among them, the bypass regulating valve 52 is preferably a needle valve, which has a more precise flow regulation capability.

[0066] In some embodiments, a bypass valve 51 is connected in series in the bypass channel 5, and the opening and closing of the bypass channel 5 can be directly controlled by controlling the bypass valve 51. The bypass valve 51 is preferably a butterfly valve, ball valve, etc.

[0067] In some embodiments, the main channel of the diversity flow component 4 or the passage connected to the main interface 2 is provided with a main channel valve 23;

[0068] And / or, the branch channel of the diversity flow component 4 or the passage connecting it to the branch interface 3 is provided with a branch valve 33.

[0069] like Figure 3 As shown, a main valve 23 is connected in series between the main interface 2 and the main channel of the distribution flow component 4, and the main valve 23 controls the on / off connection between the main channel and the large temperature control device.

[0070] And / or, the branch channel of the flow distribution assembly 4 or the passage connecting it to the branch interface 3 is provided with a branch valve 33, which controls the opening and closing of the branch channel and the temperature control unit.

[0071] Among them, the main valve 23 and the branch valve 33 are preferably shut-off valves or manual valves, such as butterfly valves and ball valves.

[0072] In some embodiments, the main channel of the diversity stream component 4 or the path connected to the main interface 2 is provided with a voltage regulator component 25.

[0073] like Figure 3 As shown, when the flow distribution component 4 is used as a flow divider 41, the main channel of the flow divider 41 is used to receive the constant temperature fluid produced by the large temperature control equipment. Through the action of the pressure stabilizing component 25, the fluid pressure output from the branch channel and the branch interface 3 can be kept stable, reducing the pressure fluctuation of the fluid in the temperature control component.

[0074] In some embodiments, the main channel of the diversity flow component 4 or the path connected to the main interface 2 is provided with a main flow statistics component 26;

[0075] And / or, the branch channel of the diversity flow component 4 or the path connected to the branch interface 3 is provided with a branch flow statistics component 34.

[0076] By connecting the main flow statistics component 26 in series between the main interface 2 and the main channel of the diversity flow component 4, the total flow rate of the fluid flowing through the main interface 2 can be counted. By connecting the branch flow statistics component 34 in series between the branch interface 3 and the branch channel of the diversity flow component 4, the flow rate of each branch can be counted.

[0077] like Figure 3 As shown, when the flow distribution component 4 is used as the flow collector 42, the main flow statistics component 26 is connected in series between the main channel and the main return water interface 22 of the flow collector 42 to count the total return water volume. The branch flow statistics component 34 is connected in series between the branch channel and the branch return water interface 32 of the flow collector 42 to count the return water volume of each branch.

[0078] like Figure 1 As shown, a main display module is set outside the cabinet 1 to display the statistical results of the total return water volume; and a branch display module is set outside the cabinet 1 in correspondence with the branch return water interface 32 to display the statistical results of the branch return water volume; and in the design, the branch regulating valve 35 is set between the branch channel of the collector 42 and the branch return water interface 32, and the actuation component of the branch regulating valve 35 is set in correspondence with the branch display module.

[0079] In some embodiments, a pressure monitoring component 24 is provided at the main interface 2 for monitoring the fluid pressure within the main interface 2.

[0080] like Figure 3 As shown, pressure monitoring components 24 are installed between the main channel of the distributor 41 and the main inlet interface 21 and between the main channel of the collector 42 and the main return interface 22, respectively, to monitor the total inlet pressure and the total return pressure. The display modules of the two pressure monitoring components 24 are arranged in a one-to-one correspondence with the main inlet interface 21 and the main return interface 22.

[0081] The pressure monitoring component 24 preferably uses a pressure gauge, and the dial of the pressure gauge is located outside the cabinet 1 for easy observation of the reading.

[0082] In some embodiments, an exhaust assembly 7 is provided at the high position of the diversity flow assembly 4;

[0083] And / or, a drainage component 6 is provided at the lower position of the flow distribution component 4.

[0084] like Figure 3 As shown, an exhaust assembly 7 is provided at the top of the distributor 41, which helps to discharge the gas released from the constant temperature fluid, reduce the gas content of the fluid entering the temperature control unit, and improve the temperature control effect of the temperature control unit.

[0085] like Figure 3 As shown, a drainage component 6 is provided at the bottom of the collector 42, which helps to fully drain the fluid in the temperature control unit and facilitates the maintenance of the heat exchange components of the temperature control unit.

[0086] In some embodiments, the diversity stream component 4 includes a splitter 41 and a collector 42;

[0087] Main interface 2 includes main water inlet interface 21 and main water return interface 22;

[0088] Branch interface 3 includes branch water inlet interface 31 and branch water return interface 32;

[0089] The main channel of the diverter 41 is connected to the main inlet interface 21, and the branch channel of the diverter 41 is connected to the branch inlet interface 31.

[0090] The main channel of the collector 42 is connected to the main return water interface 22, and the branch channel of the collector 42 is connected to the branch return water interface 32.

[0091] like Figure 1 and Figure 2 As shown, cabinet 1 contains both a distributor 41 and a collector 42. The distributor 41 is used to distribute the constant temperature fluid to the corresponding temperature control unit. The return liquid from the temperature control unit is collected by the collector 42 and then flows back into the temperature control equipment.

[0092] Furthermore, the main water inlet interface 21 and the main water return interface 22 are arranged on the same side of the cabinet 1, which facilitates the construction of connection pipelines with the temperature control equipment; while the branch water inlet interface 31 and the branch water return interface 32 are respectively arranged on both sides of the cabinet 1, which facilitates the construction of connection pipelines with multiple temperature control units and reduces interference between pipelines.

[0093] In some embodiments, the distribution device further includes a cabinet 1, the distribution component 4 is arranged inside the cabinet 1, and the main interface 2 and the branch interface 3 both extend to the outside of the cabinet 1.

[0094] At least one side of the cabinet 1 is provided with a removable or openable cabinet door for internal maintenance of the cabinet 1.

[0095] like Figure 1 and Figure 2 As shown, the diversity flow component 4 is arranged inside the cabinet 1 to facilitate protection of the diversity flow component 4 and prevent damage. The main interface 2 and the branch interface 3 are extended to the outside of the cabinet 1 to facilitate pipe connection.

[0096] like Figure 1 and Figure 2 As shown, the collector 42 and the splitter 41 inside the cabinet 1 are arranged in parallel. The connecting pipes of the two and the branch interface 3 are arranged in two parallel rows and are close to the side wall of the cabinet 1. Therefore, a detachable or openable cabinet door is provided at the corresponding side wall to facilitate the inspection and maintenance of the pipes inside the equipment and improve the maintenance convenience of the equipment.

[0097] like Figure 2 As shown, in the internal design of cabinet 1, the branch return water interface 32 and the branch inlet water interface 31 are respectively arranged on opposite sides of cabinet 1. The main channels of the splitter 41 and the collector 42 are arranged vertically. The branch channels of the splitter 41 are connected to the branch inlet water interface 31 by straight pipes in a one-to-one correspondence. The branch channels of the collector 42 are connected to the branch return water interface 32 through bent pipes. The branch regulating valve 35 is set at the bend of the pipe. The actuator of the branch regulating valve 35 is extended to the outside of the cabinet. The actuator is arranged in a one-to-one correspondence with the branch return water interface 31. The branch flow statistics component 34 is set in the straight pipe end of the bent pipe. The display module of the branch flow statistics component 34 is extended to the outside of cabinet 1 and is set in a one-to-one correspondence with the actuator of the branch regulating valve 35. At the same time, the display module of the main flow statistics component 26 is set on the same side as the display module of the branch flow statistics component 34, which facilitates the statistical observation of branch flow and total flow.

[0098] In some embodiments, the cabinet 1 is provided with a wheeled walking assembly 9;

[0099] And / or, the bottom of the cabinet 1 is provided with detachable support legs 8, and the support legs 8 and the walking assembly 9 are selected for load-bearing of the cabinet 1.

[0100] like Figure 1 and Figure 2 As shown, a wheeled walking component 9 is installed at the bottom of the cabinet 1 to enable it to walk, making it easy to move and improving its flexibility;

[0101] Meanwhile, detachable support legs 8 are installed at the bottom of the cabinet 1. When the support legs 8 are installed, the walking component 9 is off the ground and becomes ineffective, so that the cabinet 1 has relatively stable support.
