Description

Technical Field

[0001] This utility model relates to the field of transfer valve technology, and more specifically, to a multi-connector transfer valve. Background Technology

[0002] To improve filtration efficiency during vacuum oil filtration of transformer insulating oil, a single oil filter often connects to multiple insulating oil tanks. Multi-connector valves are required on-site to allow one filter to connect to multiple tanks. However, due to space constraints, the distance between each tank and the filter varies, and the length and direction of the connecting pipes differ. Longer pipes or complex routing increase frictional losses as the fluid passes through, leading to higher flow resistance. Because of these varying flow resistances, the inlet speed of each tank may be inconsistent. For tanks located further away or with more complex piping, the rate at which the insulating oil enters the filter decreases, resulting in inconsistent total filtration capacity for each tank. The total filtration capacity is the product of the flow rate and time of the insulating oil through the filtration pipeline. Currently used multi-connector valves only control valve opening and closing and cannot automatically adjust the flow rate as needed. Utility Model Content

[0003] The present invention aims to provide a multi-connector valve to solve the problem that in the prior art, when connecting an oil filter to multiple oil tanks through a multi-connector valve, the distance between each oil tank and the oil filter is inconsistent due to the limited space on site, and the different lengths and directions of the connecting pipes, resulting in inconsistent total capacity of insulating oil filtration for each oil tank. However, the existing multi-connector valves only have the function of controlling the valve opening and closing and cannot adjust the flow rate as needed.

By adjusting each flow divider control valve, the flow through the oil tank connector can be quickly adjusted so that the flow measured by each flow divider sensor is the same, thus ensuring that the flow is equal and the total filtering capacity of insulating oil in each oil tank is consistent.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1 like Figures 1-3 As shown, this embodiment proposes a multi-connector adapter valve, including an adapter valve body 1. One side of the adapter valve body 1 is provided with an oil filter connector 1-2, and the other side of the adapter valve body 1 is provided with multiple oil tank connectors 1-3.

[0026] Preferably, the adapter valve body 1 includes a cylinder, the two ends of the cylinder are closed, one side of the cylinder is provided with an oil filter interface, the other side of the cylinder is provided with multiple oil tank interfaces, the oil filter connector 1-2 is fixedly connected to the oil filter interface, and the oil tank connector 1-3 is fixedly connected to the oil tank interface.

[0027] Preferably, the oil filter connector 1-2 and the oil tank connector 1-3 are fixedly connected to the adapter valve body 1 or are directly integrally formed.

[0028] In this embodiment, three oil tank connectors 1-3 are provided. The number of oil tank connectors 1-3 can be designed according to requirements.

[0029] The inside of the transfer valve body 1 is provided with a flow equalization plate 1-1. The flow equalization plate 1-1 is arranged between the oil filter interface and the oil tank interface. The length direction of the flow equalization plate 1-1 is the same as the length direction of the cylinder. Multiple holes are opened on the flow equalization plate 1-1.

[0030] Preferably, the flow equalization plate 1-1 is fixedly connected to the transfer valve body 1.

[0031] Preferably, the interior of the transfer valve body 1 is provided with two flow equalization plates 1-1, which are arranged in parallel, dividing the interior of the transfer valve body 1 into three spaces. The insulating oil in the oil tank 11 first enters the space between the oil tank interface and the first flow equalization plate 1-1, then enters the space between the two flow equalization plates 1-1, and finally enters the space between the oil filter interface and the second flow equalization plate 1-1. The flow equalization plate 1-1 not only has the function of equalizing flow, but also has the effect of filtering impurities.

[0032] Preferably, the transfer valve body 1 is made of metal, and the flow equalization plate 1-1 is welded inside the transfer valve body 1.

[0033] A total flow sensor 3 is installed on the oil filter connector 1-2, and a flow divider sensor is installed on the oil tank connector 1-3. The total flow sensor 3 and each of the flow dividers are used to measure the flow rate of the fluid in real time.

[0034] Preferably, each of the oil tank joints 1-3 is equipped with a flow divider sensor, namely a first flow divider sensor 5-1, a second flow divider sensor 5-2, and a third flow divider sensor 5-3.

[0035] The oil filter connector 1-2 is equipped with a total flow control valve 4, and the oil tank connector 1-3 is equipped with a flow distribution control valve. The total flow control valve 4 and the flow distribution control valve are used to adjust the flow rate through the connector.

[0036] Preferably, a first flow control valve 6-1 and a second flow control valve 6-2 are respectively installed on two of the oil tank joints 1-3, while no flow control valve is installed on the other oil tank joint 1-3. The first flow control valve 6-1 and the first flow sensor 5-1 are installed on the same oil tank joint 1-3, and the second flow control valve 6-2 and the second flow sensor 5-2 are installed on the same oil tank joint 1-3.

[0037] Preferably, the two tank joints 1-3 equipped with the flow control valve are located on both sides of the other tank joint 1-3 that is not equipped with the flow control valve.

[0038] When the real-time flow rate measured by the total flow sensor 3 is Q, the real-time flow rates measured by the three individual flow sensors should be: By adjusting the opening degrees of the first flow split control valve 6-1 and the second flow split control valve 6-2, the flow rates measured by the first flow split sensor 5-1 and the second flow split sensor 5-2 are both made to reach [the specified value]. Thus, the flow rate measured by the third flow sensor 5-3 also reaches... .

[0039] By adjusting the flow rate of each oil tank joint 1-3 to be consistent using the above method, the total amount of insulating oil entering the oil filter is the same for each oil tank.

[0040] Because this utility model is equipped with a total flow sensor 3 and various branch flow sensors, it can display the real-time flow and total flow of each joint when vacuum filtering the insulating oil of the main transformer.

[0041] Because this utility model is equipped with a flow control valve, the fluid flow rate of the oil tank joint can be quickly adjusted and the flow rate of each oil tank joint can be made equal, thereby ensuring that the total capacity of insulating oil filtration in each oil tank is consistent.

[0042] Example 2 The difference between this embodiment and Embodiment 1 is that: like Figure 4 As shown, the oil filter connector 1-2 is connected to the oil filter 10 via a first oil inlet pipe 12-1. The first oil inlet pipe 12-1 is connected to the oil filter inlet 10-1 of the oil filter 10. Each oil tank connector 1-3 is connected to the oil tank outlet 11-1 of an oil tank 11 via a second oil inlet pipe 12-2 (i.e., multiple oil tank connectors 1-3 are connected to multiple oil tanks 11 one by one). In this way, the insulating oil in the oil tank 11 can be transported to the inside of the oil filter 10.

[0043] Furthermore, the oil tank 11 is connected to the oil filter outlet 10-2 of the oil filter 10 via a second oil outlet pipe 14-2, a three-way adapter 13, and a first oil outlet pipe 14-1. Specifically, the oil inlet 11-2 of each oil tank 11 is connected to the corresponding three-way adapter phase valve 13-2 of the three-way adapter 13 via a second oil outlet pipe 14-2. The main valve 13-1 of the three-way adapter 13 is connected to the oil filter outlet 10-2 of the oil filter 10 via the first oil outlet pipe 14-1. In this way, the filtered insulating oil can be delivered to each oil tank 11. The three-way adapter 13 is existing technology.

[0044] Using the above structure, the insulating oil in the oil tank 11 can be transported to the inside of the oil filter 10. After vacuum filtration, the insulating oil is then transported through the oil filter outlet 10-2 of the oil filter 10 to the first oil outlet pipe 14-1. After entering the one-to-three adapter 13, it is transported to each oil tank 11 through each second oil outlet pipe 14-2.

[0045] Example 3 The difference between this embodiment and Embodiment 1 is that: like Figure 3 As shown, the multi-connector valve also includes an industrial control touch screen all-in-one machine 2. The total flow sensor 3 and each of the branch flow sensors are respectively connected to the industrial control touch screen all-in-one machine 2 through flow signal cables. The total flow control valve 4 and each of the branch flow control valves are respectively connected to the industrial control touch screen all-in-one machine 2 through flow control cables.

[0046] In this embodiment, the industrial control touch screen all-in-one machine 2 is connected to the first flow distribution sensor 5-1 via the first flow signal cable 8-1, to the second flow distribution sensor 5-2 via the second flow signal cable 8-2, to the third flow distribution sensor 5-3 via the third flow signal cable 8-3, and to the total flow sensor 3 via the fourth flow signal cable 8-4.

[0047] The industrial control touch screen all-in-one machine 2 is connected to the first sub-flow control valve 6-1 via the first flow control cable 9-1, to the second sub-flow control valve 6-2 via the second flow control cable 9-2, and to the total flow control valve 4 via the third flow control cable 9-3.

[0048] The industrial control touch screen 2 reads signals from four flow sensors through the flow signal cable, transmits control commands through the flow control cable to control the opening of the flow control valve, and displays relevant information (running time, real-time flow, total flow, alarm information, etc.) on the industrial control touch screen 2.

[0049] The industrial control touch screen all-in-one machine 2 is fixedly installed at one end of the transfer valve body 1.

[0050] The industrial control touch screen all-in-one machine 2 is equipped with a data acquisition module, a processing module, and a control module. The flow data measured by the total flow sensor 3 and each of the branch flow sensors are transmitted to the data acquisition module and displayed on the industrial control touch screen all-in-one machine 2. The processing module is used to perform calculations on the data (for example, when the real-time flow measured by the total flow sensor is Q, the target value of the average flow at each oil tank joint is calculated). Compare the real-time flow rate measured by the flow divider sensor with it; if it is greater than... If the opening of the flow control valve is smaller, then adjust the opening of the flow control valve. Then, increase the opening of the flow control valve to ensure that the real-time flow measured by each flow sensor is equal. The system transmits control commands to the control module based on the calculation results. The control module then transmits the control commands to the flow control valves via the flow control cable. This control module is used to control and adjust the opening of each of the sub-flow control valves, and can also control the opening and closing of the total flow control valve 4 and its opening, thereby achieving automatic flow control.

[0051] The industrial control touch screen all-in-one machine 2 and all cables are existing technologies and can be directly used with existing products.

[0052] Example 4 The difference between this embodiment and Embodiment 1 is that: Manual valve 7 is installed on oil tank joints 1-3 that do not have a flow control valve installed.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
