[0017] The angle-type intelligent flow measurement and control device of this utility model, such as Figure 1 As shown, the device includes a water injection housing 10, a metering unit 20, a control unit 30, and an execution unit 40. The water injection housing 10 has an inlet end and an outlet end. The metering unit 20 is located inside the water injection housing 10 near the inlet end and is used to measure the inlet flow rate. The control unit 30 is located above the water injection housing 10 and connected to the metering unit 20. The control unit 30 is used to receive and display the inlet flow rate measured by the metering unit 20 and to issue a control signal based on the inlet flow rate.

It is used to control the outlet flow rate based on the control signal. The execution unit 40 includes a valve mounting seat 41, a grinding wheel valve 42, an electric actuator 43, and a flexible connecting pipe 44. The valve mounting seat 41 is welded to the water injection housing 10 near the outlet end. The grinding wheel valve 42 is detachably installed inside the valve mounting seat 41.

[0018] In use, the valve mounting seat 41 and the grinding wheel valve 42 are installed separately, which reduces the size of the movable grinding wheel valve 42 and greatly reduces the inconvenience of disassembly and assembly. Therefore, it significantly improves the efficiency of oil production, reduces working costs, and improves economic benefits.

[0019] Furthermore, the water injection housing 10 includes: a vertical sleeve 11 and a horizontal pipe section 12, with the water inlet located at the lower end of the vertical sleeve 11 and a connection port provided on the side of the vertical sleeve 11; a metering unit 20 is disposed inside the vertical sleeve 11, and a control unit 30 is disposed at the upper end of the vertical sleeve 11 and passes through the upper port of the vertical sleeve 11 to connect with the metering unit 20; the horizontal pipe section 12, with its first end vertically connected to the vertical sleeve 11 through the connection port, and its second end forming a water outlet; and an execution unit 40 installed on the horizontal pipe section 12 to control the water flow rate at the water outlet.

[0020] In use, the metering unit 20 transmits the water flow measurement data at the inlet to the control unit 30. The control unit 30 feeds back the received signal to the execution unit 40. The execution unit 40 can control the water flow at the outlet according to the signal, so as to realize the automatic opening and closing angle of the grinding wheel valve 42, thereby adjusting the water flow at the outlet.

[0021] Furthermore, the water injection housing 10 also includes: a welding flange 13 and a clamping flange 14. The welding flange 13 is located above the vertical sleeve 11 and is welded to the vertical sleeve 11. In use, the metering unit 20 is detachably installed inside the vertical sleeve 11 through the through hole of the welding flange 13.

The magnet 222 inside the measuring housing 22 is above the shunt column 221.

[0024] When in use, the water flow passes through the magnet 222 built into the measuring housing 22 to generate an induced voltage. The induced voltage is transmitted to the smart meter 33 of the control unit 30 through the electrodes, so that the measured water flow is accurately displayed on the smart meter 33.

[0025] Furthermore, the upper housing 21 has a first rectangular groove on its side, and the lower surface of the first rectangular groove is at the same level as the upper surface of the welding flange 13 during installation; the measuring housing 22 has multiple openings evenly distributed on its side, and the openings connect to the transverse horizontal pipe section 12; the measuring housing 22 also includes a boss 223, the bottom of the boss 223 has a sealing groove around the measuring housing 22, and the lower part of the boss 223 has a sealing groove around the measuring housing 22.

A seal is provided at the bottom of the boss 223 and below the measuring housing 22. When water flows through the measuring housing 22, it can be ensured that the water will not leak from the gap between the measuring housing 22 and the water injection housing 10, making the water flow rate measured by the measuring housing 22 more accurate.

[0027] Furthermore, the control unit 30 includes: a sensor 31, a connector 32, and a smart meter 33. The lower part of the sensor 31 is inserted into the metering unit 20, and the sensor 31 is used to process the induced voltage collected by the metering unit 20. The connector 32 is detachably disposed above the water injection housing 10.

The smart meter 33 is installed on the upper part of the connector 32, and the sensor 31 transmits the flow signal to the smart meter 33 through the connecting wire.

[0028] Furthermore, the connector 32 is filled with glue, and both the upper and lower ends of the connector 32 are provided with annular sealing grooves for installing sealing rings.

The control unit 30 is connected to the electric actuator 43 through the flexible connecting pipe 44. The control unit 30 sends valve position feedback information to the electric actuator 43 for valve position adjustment.

[0031] Furthermore, a clamping nut 45 is installed above the valve mounting seat 41, and the grinding wheel valve 42 is detachably installed inside the valve mounting seat 41 via the clamping nut 45; the flexible connecting pipe 44 is made of high temperature resistant material.

[0032] When in use, the entire grinding wheel valve 42 can be removed by manually unscrewing the clamping nut 45, which greatly reduces the inconvenience of valve disassembly and assembly.

[0033] Furthermore, the electric actuator 43 can be adjusted automatically or manually.

[0034] In use, the grinding wheel valve 42 can be automatically adjusted by the electric actuator 43 to change the valve opening value, or the electric actuator 43 can be manually adjusted to change the valve opening value of the grinding wheel valve 42, thereby realizing the flow regulation at the outlet end.
