Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, specifically to a regulating valve with a measuring mechanism. Background Technology

[0002] Control valves, also known as regulating valves, are crucial components in industrial automation process control used to regulate process parameters such as flow rate, pressure, temperature, and liquid level. They automatically adjust the valve opening based on control signals from the automation system, thereby achieving precise control of process parameters.

[0003] During use, the valve core and seat of a control valve are easily contaminated by impurities and particles in the medium. The lack of a structure to filter impurities or particles can lead to valve jamming and incomplete closure, which can affect the performance and reliability of the control valve and may even cause system failure, failing to meet production requirements. Therefore, a control valve with a measuring mechanism is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a regulating valve with a measuring mechanism, which has the advantages of filtering out residual impurities or particles in flowing liquids. It solves the problem that the valve core and valve seat are easily contaminated by impurities and particles in the medium during the use of the regulating valve, and the lack of a structure to filter impurities or particles leads to valve jamming and incomplete closure. This affects the performance and reliability of the regulating valve and may even lead to system failure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a regulating valve with a measuring mechanism, comprising a regulating valve body, a filter element inserted into the lower right end of the regulating valve body, a plurality of filter holes being formed on the surface of the filter element, a measuring mechanism being provided on the right side of the regulating valve body, and a regulating mechanism for regulating the liquid flow rate being provided on the lower side of the regulating valve body.

[0006] The measuring mechanism includes a fixed seat fixedly connected to the right side of the regulating valve body, a sensor fixedly installed on the inner wall of the fixed seat, a second tension spring connecting block fixedly connected to the right side of the sensor, a tension spring fixedly connected to the lower side of the second tension spring connecting block, and a first tension spring connecting block fixedly connected to the lower side of the tension spring.

[0007] Furthermore, the adjusting mechanism includes a threaded cylinder rotatably sleeved on the inner wall of the regulating valve body, a threaded rod threadedly connected to the inner wall of the threaded cylinder, a piercing plug fixedly sleeved on the lower side of the threaded rod, a piercing plug seat fixedly sleeved inside the lower side of the regulating valve body, and a rotating assembly disposed on the outer side of the threaded rod.

[0008] Furthermore, the rotating assembly includes a second bearing rotatably sleeved on the outer wall of the threaded rod and a first bearing rotatably sleeved on the upper outer wall of the threaded rod.

[0009] Furthermore, a limiting component is provided on the outer side of the threaded rod. The limiting component includes sliders fixedly connected to the left and right sides of the threaded rod and a groove formed on the lower inner wall of the regulating valve body.

[0010] Furthermore, a conveying assembly for liquid flow is provided on the lower side of the regulating valve body. The conveying assembly includes an outlet connected to the left end of the lower side of the regulating valve body and an inlet connected to the right end of the lower side of the regulating valve body.

[0011] Furthermore, a sealing ring is fixedly fitted on one end of the lower side of the regulating valve body near the second bearing, and the inner wall of the sealing ring is in contact with the outer wall of the threaded rod.

[0012] Furthermore, a limiting plate is fixedly connected to the right side of the filter element, and the outer side of the filter element is sleeved on the inner wall surface of the liquid inlet.

[0013] Compared with the prior art, the present invention provides a regulating valve with a measuring mechanism, which has the following advantages:

[0014] 1. The regulating valve with a measuring mechanism is inserted and clipped to the liquid inlet side of the lower right end of the regulating valve body by one side of the filter element, and can effectively fit the outer surface of the liquid inlet. When the liquid passes through, the filter holes opened on the surface of the filter element are used to filter the liquid and filter out the impurities or particles in the liquid, thereby effectively improving the service life of the regulating valve body and avoiding the valve core or valve seat from getting stuck.

[0015] 2. This regulating valve with a measuring mechanism uses a threaded cylinder to drive a threaded rod on the inner wall, moving the vertebral plug towards the vertebral plug seat. Simultaneously, the tension spring, connected by the first bearing, works with a sensor to effectively determine the speed ratio based on the tension length generated by the spring. This solves the problem that during use, the valve core and valve seat are easily contaminated by impurities and particles in the medium, lacking a structure to filter impurities or particles, leading to valve jamming and incomplete closure. This affects the performance and reliability of the regulating valve and may even cause system failure. Attached Figure Description

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.

[0022] Please see Figure 1-4 This embodiment of a regulating valve with a measuring mechanism includes a regulating valve body 1, a filter element 12 inserted into the lower right end of the regulating valve body 1, a plurality of filter holes 13 formed on the surface of the filter element 12, a measuring mechanism disposed on the right side of the regulating valve body 1, and a regulating mechanism for regulating the liquid flow rate disposed on the lower side of the regulating valve body 1. The measuring mechanism includes a fixed base 15 fixedly connected to the right side of the regulating valve body 1, a sensor 14 fixedly installed on the inner wall of the fixed base 15, a second tension spring connecting block 16 fixedly connected to the right side of the sensor 14, a tension spring 2 fixedly connected to the lower side of the second tension spring connecting block 16, and a first tension spring connecting block 3 fixedly connected to the lower side of the tension spring 2.

[0023] The regulating mechanism includes a threaded cylinder 17 rotatably sleeved on the inner wall of the regulating valve body 1, a threaded rod 4 threadedly connected to the inner wall of the threaded cylinder 17, a cone plug 8 fixedly sleeved on the lower side of the threaded rod 4, a cone plug seat 11 fixedly sleeved inside the lower side of the regulating valve body 1, and a rotating assembly disposed on the outer side of the threaded rod 4. The rotating assembly includes a second bearing 7 rotatably sleeved on the outer wall of the threaded rod 4 and a first bearing 5 rotatably sleeved on the upper outer wall of the threaded rod 4. A limit assembly is disposed on the outer side of the threaded rod 4. The limit assembly includes a fixedly connected component on the threaded rod 4. The sliding blocks on the left and right sides and the groove opened on the lower inner wall of the regulating valve body 1. The lower side of the regulating valve body 1 is provided with a conveying component for liquid flow. The conveying component includes a water outlet 9 connected to the lower left end of the regulating valve body 1 and a liquid inlet 10 connected to the lower right end of the regulating valve body 1. A sealing ring 6 is fixedly sleeved on the lower end of the regulating valve body 1 near the second bearing 7. The inner wall of the sealing ring 6 is in contact with the outer wall of the threaded rod 4. A limit plate is fixedly connected to the right side of the filter element 12. The outer side of the filter element 12 is sleeved on the inner wall surface of the liquid inlet 10.

[0024] The working principle of the above embodiments is as follows:

[0025] Using a limiting plate, the filter element 12 is inserted from the right side of the regulating valve body 1 into the inner wall of the inlet 10. Then, the regulating valve body 1 is connected to other pipes for use. During use, liquid enters the regulating valve body 1 from the inlet 10 and is discharged from the outlet 9. The liquid flows out through the filter hole 13 after passing through the filter element 12. Impurities and particles remaining in the liquid are blocked by the filter element 12, which prevents impurities from contacting the inside of the regulating valve body 1 and causing the valve core to jam, thus extending the service life of the regulating valve body 1. During use, it can be used with the threaded cylinder 17 to drive the lower vertebra 8 of the threaded rod 4 to move into the vertebra seat 11 and adjust the flow rate of the liquid. During the movement of the threaded rod 4, the first bearing 5 extends the connected tension spring 2 through the first tension spring connecting block 3 and transmits the tension from the second tension spring connecting block 16 to the sensor 14, thereby effectively determining the speed ratio by measuring the pulling length generated by the tension spring 2 to achieve the measurement purpose.
