DETAILED DESCRIPTION

[0027] In order to make the person skilled in the art better understand the present application, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] The embodiments of the present application provide a flow assembly, which can solve the problem of unnecessary cost waste caused by the frequent replacement of the pressure regulating valve due to the insufficient gas-liquid separation effect, the electrolyte crystallization easily causing the pressure regulating valve to be blocked, and the service life of the pressure regulating valve to be greatly reduced.

[0029] As shown in Figs. 1 and 2, the embodiments of the present application provide a flow assembly, which comprises: a flow assembly 1, the flow assembly 1 is provided with an air inlet 11 and a first air outlet 12, the air inlet 11 is used to communicate with a gas-liquid separator, and the first air outlet 12 is used to communicate with a pressure regulating valve; a filter 2, the filter 2 is installed in the flow assembly 1, the filter 2 is provided with a filter inlet 21 and a filter outlet 22, the filter inlet 21 is communicated with the air inlet 11 through a pipeline 3, and the filter 2 is internally provided with a filter core. The filter core can be a filter cotton core. Figure 1 and Figure 2 As shown in Figs. 1 and 2, the embodiments of the present application provide a flow assembly, which comprises: a flow assembly 1, the flow assembly 1 is provided with an air inlet 11 and a first air outlet 12, the air inlet 11 is used to communicate with a gas-liquid separator, and the first air outlet 12 is used to communicate with a pressure regulating valve; a filter 2, the filter 2 is installed in the flow assembly 1, the filter 2 is provided with a filter inlet 21 and a filter outlet 22, the filter inlet 21 is communicated with the air inlet 11 through a pipeline 3, and the filter 2 is internally provided with a filter core. The filter core can be a filter cotton core.​

[0030] In this embodiment, the flow collector 1 is equipped with an air inlet 11 connected to a gas-liquid separator for receiving gas that has undergone preliminary gas-liquid separation, and a first air outlet 12 connected to a pressure regulating valve to ensure that a negative pressure is formed inside the flow collector 1 under the action of the pressure regulating valve. A filter 2 is installed inside the flow collector 1. The filter 2 has a filter inlet 21 and multiple filter outlets 22. The filter inlet 21 is connected to the air inlet 11 of the flow collector 1 through a pipeline 3 to ensure that the gas entering the flow collector 1 can directly enter the filter 2 for further filtration. The core part of the filter 2 is a filter core installed inside it, which can effectively remove small droplets, electrolyte crystals, and other impurities in the gas, perform secondary filtration on the gas after the gas-liquid separator, effectively remove residual electrolyte and other impurities, and significantly improve the efficiency of gas-liquid separation. Since the filter 2 effectively removes electrolyte crystals and impurities in the gas, it reduces the blockage and corrosion of the pressure regulating valve by these substances, thereby significantly extending the service life of the pressure regulating valve and reducing the frequency and cost of replacement. In addition, for negative pressure generating devices with compact layout space, by effectively utilizing the space inside the flow collector 1, the filter 2 is arranged inside the flow collector 1, without the need for additional space for the arrangement of the filter 2.

[0031] In one embodiment, as shown in Figure 1 and Figure 2 , the filter 2 is in a cylindrical shape, and the filter inlet 21 and the filter outlet 22 are both opened on the side wall of the filter 2. Along the length direction of the filter 2, the air inlet 11 and the first air outlet 12 are centrally arranged on opposite sides of the filter 2.

[0032] In this embodiment, the filter 2 is designed in a cylindrical shape, which not only facilitates uniform gas flow but also improves the utilization rate of the filter core. Because of the cylindrical shape, the pressure distribution when the gas flows through is more uniform. The filter inlet 21 and the filter outlet 22 are both opened on the side wall of the filter 2. This design allows the gas to enter the filter 2 from the side and flow out uniformly through the side filter outlet 22, further improving the filtration efficiency and uniformity of the gas. Along the length direction of the filter 2, the air inlet 11 and the first air outlet 12 are centrally arranged on opposite sides of the filter 2. This layout ensures that the gas can flow through the entire filter core when passing through the filter 2, thereby fully utilizing the filtering capacity of the filter core and improving the filtering effect. The combination of the cylindrical filter 2 and the side-opening filter inlet 21 and filter outlet 22 makes the gas flow in the filter 2 more uniform, the utilization rate of the filter core higher, and the overall filtration efficiency improved. This flow collector can more stably handle the gas and reduce system fluctuations caused by uneven gas flow or incomplete filtration.

[0033] In an embodiment, the filter 2 can also be designed as a sphere, and the filter inlet 21 and the plurality of filter outlets 22 are both arranged on the side wall of the sphere.

[0034] In an embodiment, as shown in Figure 1 and Figure 2 , the plurality of filter outlets 22 are arranged in multiple numbers, and the diameters of a part of the plurality of filter outlets 22 are larger than those of the remaining filter outlets 22.

[0035] In this embodiment, among the plurality of filter outlets 22 arranged on the side wall of the filter 2, the diameters of a part of the plurality of filter outlets 22 are designed to be larger than those of the remaining filter outlets 22. The filter outlets 22 with larger diameters can allow more gas to flow out at the same time, thereby increasing the flow rate of the gas and improving the overall gas processing efficiency, which is particularly important for formation tanks that need to quickly process a large amount of gas.

[0036] In an embodiment, the first gas outlet 12 is connected with a first vacuum breaking valve, and the first vacuum breaking valve is used to communicate with the pressure regulating valve.

[0037] In this embodiment, the introduction of the first vacuum breaking valve can quickly break the vacuum when the system needs to do so, ensuring that the gas can smoothly flow out of the first gas outlet 12 and be stably supplied to the pressure regulating valve, thereby meeting the gas demand of subsequent equipment. In the gas supply system, a vacuum state can cause some unpredictable risks. When the system needs to be maintained or overhauled, the first vacuum breaking valve can conveniently cut off the connection with the pressure regulating valve, making the maintenance work more convenient, and at the same time, it will not affect other parts of the entire gas supply system.

[0038] In an embodiment, as shown in Figure 1 , the flow collector 1 is provided with a second gas outlet 13, and the second gas outlet 13 is connected with a proportional valve, and the proportional valve is used to communicate with the pressure regulating valve.

[0039] In this embodiment, the proportional valve can accurately adjust the flow of gas passing through it, thereby ensuring the stability and accuracy of gas supply, which is crucial for systems that require strict gas flow management. Through cooperation with the pressure regulating valve, the proportional valve can achieve precise regulation of gas pressure, which not only meets the different needs of the system for gas pressure, but also improves the overall performance and stability of the system.

[0040] In an embodiment, as shown in Figure 1 , the flow collector 1 is provided with a third gas outlet 14, and the third gas outlet 14 is connected with a second vacuum breaking valve, and the second vacuum breaking valve is used to communicate with the pressure regulating valve.

[0041] In the embodiment, the presence of the second vacuum breaking valve makes the gas in the flow collector 1 more flexible to be controlled and adjusted. When it is necessary to release or adjust the gas in the flow collector 1, the second vacuum breaking valve can be opened or closed to achieve the purpose, such as forming a vacuum state in the flow collector, the second vacuum breaking valve can quickly break the vacuum to avoid the negative effects caused thereby, such as equipment damage or gas flow obstruction.

[0042] In an embodiment, as shown in Figure 1 The flow collector 1 is provided with a fourth gas outlet 15, and the fourth gas outlet 15 is communicated with a negative pressure digital display meter for communicating with the pressure regulating valve.

[0043] In the embodiment, the negative pressure digital display meter can monitor the negative pressure value in the flow collector 1 in real time, provide accurate data support for the operator, help to understand the pressure condition in the flow collector in time, and through the communication with the pressure regulating valve, the negative pressure digital display meter can assist the operator to accurately control the pressure in the flow collector 1. When the pressure reaches the preset value, the pressure regulating valve can be adjusted in time to ensure that the pressure in the flow collector 1 is stable within the safe range. The introduction of the negative pressure digital display meter increases the safety of the system. When the pressure in the flow collector 1 is abnormal, the operator can quickly find and take corresponding measures to avoid possible dangerous situations.

[0044] In an embodiment, as shown in Figure 2 The first gas outlet 12, the second gas outlet 13, the third gas outlet 14 and the fourth gas outlet 15 are distributed along the length direction of the filter 2.

[0045] In the embodiment, the filter 2 arranged horizontally cooperates with the four negative pressure gas outlets to uniformly extract negative pressure, solving the problem of uneven loss of the conventional vertically arranged filter 2.

[0046] In an embodiment, as shown in Figure 1 A through hole 16 is formed on one side of the flow collector 1, and a ring of clamping grooves 17 is formed on the side, the through hole 16 is located in the clamping groove 17, and the flow collector 1 is clamped with a sealing cover plate 18 through the clamping groove 17.

[0047] In this embodiment, a through hole 16 is specially provided on one side of the current collecting member 1, and a clamping groove 17 is also provided on the same side, and the through hole 16 is located in the clamping groove 17. The sealing cover plate 18 is clamped with the current collecting member 1 through the clamping groove 17, thereby covering and sealing the through hole 16. The clamping design of the sealing cover plate 18 and the clamping groove 17 ensures that the through hole 16 is effectively sealed. This sealing structure can prevent the leakage of gas or liquid in the current collecting member 1, and ensure the sealing of the inside of the current collecting member. The clamping structure makes the installation and disassembly of the sealing cover plate 18 relatively simple. When it is necessary to access the inside of the current collecting member 1 or to maintain, the sealing cover plate 18 can be easily disassembled, without the need for complex operations or tools, so that the filter 2 inside can be disassembled and cleaned.

[0048] In one embodiment, as shown in Figure 4 The side wall of the filter 2 is provided with a buckle member 4, and the inner wall of the current collecting member 1 is provided with a buckle groove. The buckle member 4 is configured to be clamped with the buckle groove, so that the filter 2 is fixed in the current collecting member 1.

[0049] In this embodiment, the filter 2 is designed with a buckle member 4, and the inner wall of the current collecting member 1 is correspondingly provided with a buckle groove. Through the clamping of the buckle member 4 and the buckle groove, the filter 2 can be firmly fixed in the current collecting member 1, ensuring its stability and reliability during work.

[0050] In one embodiment, as shown in Figure 4 The side wall of the filter 2 is provided with a buckle member 4, and the inner wall of the current collecting member 1 is provided with a buckle groove. The buckle member 4 is configured to be clamped with the buckle groove, so that the filter 2 is fixed in the current collecting member 1.

[0051] In one embodiment, as shown in Figure 2 As shown in the figure, the inner diameter of the pipeline 3 gradually increases along the path direction of the gas entering the pipeline 3.

[0052] In this embodiment, when the gas flows from the smaller inner diameter part of the pipeline 3 to the larger inner diameter part of the pipeline 3, the flow rate of the gas will decrease accordingly due to the increase of the cross-sectional area of the pipeline 3. This design helps to control the flow rate of the gas in the pipeline, making it more stable. By gradually increasing the inner diameter of the pipeline 3, the sharp change of the flow rate of the gas can be avoided, thereby reducing the pressure loss. When the flow rate of the gas decreases, the particulate matter in the gas has more opportunities to contact and be captured by the filter 2, thereby improving the filtering effect.
