Description

Technical Field

[0001] The present application relates to the technical field of petroleum production, and in particular to an electromagnetic water distributor. Background Art

[0002] The overall outer diameter of the water distributor is usually fixed. In actual use, the diameter of the main water flow channel is usually required to be greater than or equal to 45mm. Therefore, the installation space of the flow meter in the water distributor is greatly restricted, and only a smaller-sized flow meter can be used. The measuring flow channel of the flow meter is correspondingly narrow, and the measurement accuracy is insufficient. In addition, the length of the measuring flow channel usually needs to be set to 35mm. When the installation space is limited, the diameter of the measuring flow channel is small, and the diameter length of the measuring flow channel is relatively small, which will further affect the stability and accuracy of the measurement process.

[0028] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with examples and drawings. The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.

[0029] like Figure 1-Figure 2 As shown, an embodiment of the present application provides an electromagnetic water distributor, which includes a first end 1, a second end 2, a middle shell, an inner cylinder 4 and an electromagnetic flowmeter 5.

[0030] The first end 1 has a first flow channel 11, which can serve as the overall water inlet channel of the electromagnetic water distributor. The first end 1 as a whole can be roughly cylindrical in shape, that is, the first end 1 as a whole can be a standard cylinder, or it can be a segmented combination structure with different diameters along the length direction. When the first end 1 is set to a segmented combination structure, the electromagnetic water distributor can adapt to more installation occasions.

[0031] The second end 2 has a second flow channel 21, and the first end 1 and the second end 2 are arranged at intervals. The second flow channel 21 can serve as the overall water outlet channel of the electromagnetic water distributor. The second end 2 as a whole can also be roughly cylindrical in shape, that is, the second end 2 as a whole can be a standard cylinder, or a segmented combination structure with different diameters along the length direction. When the second end 2 is set to a segmented combination structure, the electromagnetic water distributor can adapt to more installation occasions.

[0032] The middle shell is connected to the first end 1 and the second end 2 respectively to connect the first flow channel 11 and the second flow channel 21. The middle shell as a whole can be cylindrical, and the two ends of the middle shell are respectively equal in diameter to the end faces of the first end 1 and the second end 2. The two ends of the middle shell are respectively sealed and connected to the first end 1 and the second end 2, and the inner hole of the middle shell connects the first flow channel 11 and the second flow channel 21.

[0033] The inner tube 4 has a first section 41 and a second section 42, wherein the diameter of the first section 41 is greater than the diameter of the second section 42, and the first section 41 and the second section 42 are eccentrically arranged, wherein an end of the first section 41 is connected to the first end 1, and an end of the second section 42 is connected to the second end 2, and the first flow channel 11 and the second flow channel 21 are connected through the inner tube 4.

[0034] The electromagnetic flowmeter 5 is located between the second section 42 and the middle shell, one end of the electromagnetic flowmeter 5 is connected to the inner tube 4, and the other end is connected to the outside of the middle shell, the axis of the measuring flow channel of the electromagnetic flowmeter 5 is coplanar with the axes of the first section 41 and the second section 42, and the axis of the first section 41 is located between the axis of the second section 42 and the axis of the measuring flow channel.

[0035] During operation, the main water flow passes through the first flow channel 11, the inner tube 4, and the second flow channel 21 in sequence to pass through the electromagnetic water distributor. When the main water flow flows through the inner tube 4, part of it flows into the electromagnetic flowmeter 5 to measure the flow rate. The measured water flow is discharged from the outside of the electromagnetic water distributor through the electromagnetic flowmeter 5.

[0036] The electromagnetic water distributor provided in the present application has a larger installation space between the inner cylinder 4 and the middle shell by constructing the inner cylinder 4 into a first section 41 and a second section 42 with different diameters, and eccentrically arranging the first section 41 and the second section 42. This allows for the installation of a larger electromagnetic flowmeter 5, and the measuring flow channel inside the electromagnetic flowmeter 5 is larger, so that the flow rate of the measured object is larger, which can ensure that the measurement result is more accurate. At the same time, the electromagnetic flowmeter 5 has a larger diameter-to-length ratio, the measurement process is smoother, and the reliability of the measurement result is higher.

[0037] In some optional embodiments, a flow measuring hole is provided on the first section 41, and the flow measuring hole may include a continuous first part and a second part, the axis of the first part is along the radial direction of the first section 41, and the axis of the second part is parallel to the axial direction of the first section 41, and one end of the electromagnetic flowmeter 5 is connected to the flow measuring hole through the second part, thereby realizing the connection between the electromagnetic flowmeter 5 and the inner cylinder 4.

[0038] In the embodiment of the present application, since the inner diameter of the first section 41 is different from the inner diameter of the second section 42, the flow rate of the main water flow will change to a certain extent after flowing from the first section 41 to the second section 42, and the water flow in the first section 41 is closer to the water inlet channel. After the electromagnetic flowmeter 5 is directly connected to the inner hole of the first section 41, the measurement result can be more accurate and reliable.

[0039] In some optional embodiments, the inner diameter of the end of the first section 41 is equal to the diameter of the first flow channel 11 , and the inner diameter of the first section 41 gradually decreases from its end toward the second section 42 until it is equal to the inner diameter of the second section 42 .

[0040] In the embodiment of the present application, the first section 41 is set as a variable diameter structure, and its inner hole does not have a cross-sectional structure, which can reduce the obstruction of the inner hole of the first section 41 to the main water flow and ensure the smoothness of the main water flow through the electromagnetic water distributor.

[0041] In some optional embodiments, the axial projection profile of the second section 42 is inscribed in the axial projection profile of the first section 41. This arrangement enables the second section 42 to have a maximum spacing with the middle housing, thereby providing a larger installation space for the electromagnetic flowmeter 5, so that a larger-sized electromagnetic flowmeter 5 can be used in the water distributor; at the same time, the installation space is larger, and the specification selection of the electromagnetic flowmeter 5 is more diverse, and more electromagnetic flowmeters 5 with different diameter-to-length ratios can be selected as needed to meet different measurement requirements.

[0042] In some optional embodiments, an annular flow channel 22 is provided in the second end portion 2, and the annular flow channel 22 has a first connecting hole and a second connecting hole, wherein the first connecting hole is connected to the other end of the electromagnetic flowmeter 5, and the second connecting hole is connected to the outside of the second end portion 2, and an adjustable water nozzle 6 is arranged at the second connecting hole.

[0043] In the embodiment of the present application, through the setting of the annular flow channel 22, the measuring water flow in the electromagnetic flowmeter 5 can flow out from one radial side of the second section 42, and this side has a certain installation space, that is, there is also a certain distance between the second section 42 on this side and the middle shell 3, allowing the installation of an adjustable water nozzle 6. After the adjustable water nozzle 6 is configured for the second connecting hole, the flow size of the second flow hole can be adjusted by the adjustable water nozzle 6, thereby realizing the adjustment of the internal water pressure of the electromagnetic flowmeter 5, ensuring the stability of the internal water flow of the electromagnetic flowmeter 5, and then ensuring the stability of the measurement process and the accuracy of the measurement results.

[0044] Of course, if the installation requirements are large, for example, a larger adjustable water nozzle 6 is required, the positions of the adjustable water nozzle 6 and the electromagnetic flowmeter 5 are not necessarily arranged relative to each other. Due to the diameter difference between the first end and the second section 42, there is still a large installation space on both sides of the electromagnetic flowmeter 5, and the adjustable water nozzle 6 can be installed in the installation space. At this time, the adjustable water nozzle 6 can be installed separately, that is, the driving part is located in the aforementioned installation space, and the execution part is installed in the second flow hole.

[0045] Preferably, the first connecting hole and the second connecting hole are arranged in a central symmetric manner. With this arrangement, the water in the electromagnetic flowmeter 5 can enter the annular flow channel 22 from the first flow hole after flowing out, and then flow out of the water distributor from the second flow hole after a longer path, which is conducive to ensuring the stability of the water flow measured in the electromagnetic flowmeter 5, that is, the measurement process is more stable, thereby ensuring the accuracy of the measurement result.

[0046] In some optional embodiments, the eccentricity of the first section 41 and the second section 42 is configured to be 5.8-6.2 mm. On the basis that the axial profile of the second section 42 is inscribed in the axial profile of the first section 41, the eccentricity is configured to be 5.8-6.2 mm, which can provide sufficient installation space for the electromagnetic flowmeter 5, and the inner diameter of the second section 42 can be maintained at an appropriate value, which has less impact on the circulation of the main water flow.

[0047] Preferably, the eccentricity between the first section 41 and the second section 42 is configured to be 6 mm.

[0048] In some optional embodiments, the adjustable water nozzle 6 is configured as a ceramic water nozzle and is connected to the second end 2, wherein the adjustable water nozzle 6 is configured with a motor to adjust the opening under the drive of the motor, and the motor is located between the middle shell and the inner tube 4.

[0049] In some optional embodiments, a pressure gauge 7 is disposed on the first end 1 to detect the external environmental pressure of the first end 1 .

[0050] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the present application in detail. It should be understood that the above description is only the specific implementation method of the present application and is not intended to limit the scope of protection of the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
