Description

Technical Field

[0001] This utility model relates to the field of flow control valve technology, specifically to a flow control valve that is easy to adjust. Background Technology

[0002] Flow control valves are indispensable key components in industrial fluid transport and control systems. They are widely used in many fields such as petroleum, chemical, metallurgy, power and municipal water supply. Their core function is to accurately regulate and stabilize the flow rate of the medium in the pipeline to meet process requirements or system balance.

[0003] Traditional manual valves mostly use a handwheel-driven valve stem structure. When the operator rotates the handwheel, there is a lack of clear and real-time mechanical feedback, making it difficult to accurately control the small opening changes of the valve core. They often rely on experience or repeated comparison of flow meter readings, resulting in low efficiency and difficulty in guaranteeing accuracy during the adjustment process. Electric valves, on the other hand, cannot be used when there is an unexpected power outage, which affects flow control. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Please see Figures 1 to 8 This utility model discloses an easily adjustable flow control valve, including a valve seat 1, and further including: a valve cover 2 fixedly installed on the top surface of the valve seat 1, a rotating rod 3 rotatably mounted on the top surface of the valve cover 2, a valve rod assembly 4 internally threadedly connected to the rotating rod 3, a rotating handwheel 5 fixedly mounted on the top of the rotating rod 3; a rubber sleeve gear 6 fixedly mounted on the bottom surface of the rotating rod 3, an adjustment feedback gear sleeve 7 sleeved on the surface of the rubber sleeve gear 6, an angle scale 8 fixedly mounted on the top surface of the adjustment feedback gear sleeve 7, and a positioning assembly 9 fixedly mounted on one side of the outer surface of the rotating rod 3. After adjustment, the operator rotates the positioning gear 92 and engages it with the positioning engagement tooth 14 to fix the rotating rod 3, preventing displacement caused by vibration of the medium flow.

[0033] A scale pointer 10 is fixedly installed on the side of the outer surface of the rotating rod 3 away from the positioning component 9. With the setting of the rubber sleeve gear 6, the adjustment feedback gear sleeve 7, the angle scale 8 and the scale pointer 10, when manually adjusting, the operator rotates the handwheel 5, so that the rubber sleeve gear 6 rotates in the adjustment feedback gear sleeve 7. Since the rubber sleeve gear 6 and the adjustment feedback gear sleeve 7 are slightly meshed, the operator will receive feedback in real time when rotating, which is convenient for the operator to make precise adjustments. At the same time, the scale pointer 10 indicates the reading on the angle scale 8, and the flow meter 17 is used to display the flow reading in real time, realizing the visualization and precision of the adjustment process.

[0034] A fixing bracket 11 is fixedly installed on the edge of the top surface of the valve cover 2. A servo motor 12 is fixedly installed on one side of the fixing bracket 11. A connecting component 13 is fixedly installed at the output end of the servo motor 12. With the setting of the connecting component 13, when adjusting electrically, the electric push rod 131 is opened, so that the cross connecting block 132 is inserted into the cross groove of the rotating handwheel 5. The servo motor 12 drives the cross connecting block 132 to rotate, so that the rotating handwheel 5 rotates accordingly. This realizes the integration of manual and electric adjustment. Electric adjustment is performed when the power is on normally, and manual adjustment is performed when the power is accidentally cut off, ensuring the use of the flow control valve.

[0035] Furthermore, the positioning component 9 includes a fixed rod 91 fixedly disposed on one side of the outer surface of the rotating rod 3, and a positioning tooth 92 rotatably disposed at one end of the fixed rod 91 via a damping shaft; a positioning engagement tooth 14 is fixedly disposed on the edge of the top surface of the adjustment feedback sleeve 7, the positioning engagement tooth 14 is adapted to the positioning tooth 92, and the bottom of the adjustment feedback sleeve 7 is fixedly connected to the valve cover 2.

[0036] In this embodiment, the operator rotates the positioning toothed rod 92 and engages it with the positioning engagement tooth 14 to fix the rotating rod 3, thus preventing displacement caused by vibration of the medium flow.

[0037] Furthermore, the valve stem assembly 4 includes a valve stem 41 threadedly connected to the inside of the rotating rod 3, and a valve plate 42 is fixedly installed at the bottom of the valve stem 41; positioning rods are fixedly installed on both sides of the inner top wall of the valve cover 2, and a limit rod 15 is slidably installed inside the positioning rod.

[0038] In this embodiment, when the rotating rod 3 rotates, the valve stem 41, which is threadedly connected to the rotating rod 3, moves up and down, driving the valve plate 42 up and down. When the valve stem 41 moves up and down, the limiting rod 15 slides synchronously inside the positioning rod to limit the valve stem 41 and is used to regulate the flow rate.

[0039] Furthermore, the connecting component 13 includes an electric push rod 131 fixedly mounted on the output end of the servo motor 12, and a cross connecting block 132 fixedly mounted on the output end of the electric push rod 131; positioning tubes are fixedly mounted on both sides of the bottom surface of the servo motor 12, and an anti-torque rod 16 is slidably mounted inside the positioning tube, with the bottom of the anti-torque rod 16 fixedly connected to the cross connecting block 132; a cross groove is provided in the middle of the top surface of the rotating handwheel 5, and the cross groove is adapted to the cross connecting block 132.

[0040] In this embodiment, during electric adjustment, the electric push rod 131 is opened, so that the cross connecting block 132 is inserted into the cross groove of the rotating handwheel 5. The servo motor 12 drives the cross connecting block 132 to rotate, so that the rotating handwheel 5 rotates accordingly. The anti-torque rod 16 is used to bear the torque of the electric push rod 131 to avoid damage.

[0041] Furthermore, an inlet pipe is provided through one side of the valve seat 1, and an outlet pipe is provided through the other side of the valve seat 1. A flow meter 17 is fixedly installed on the surface of the outlet pipe.

[0042] In this embodiment, the flow meter 17 is used to monitor the flow rate of the outlet pipe.

[0043] Furthermore, the inner wall of the adjustment feedback gear sleeve 7 is provided with several blocking grooves in a ring array, and the blocking grooves are adapted to the rubber sleeve gear 6.

[0044] In this embodiment, the retaining groove is used to slightly impede the rubber sleeve gear 6.

[0045] The working principle and usage process of this utility model: When adjusting electrically, the electric push rod 131 is opened, so that the cross connecting block 132 is inserted into the cross groove of the rotating handwheel 5. The servo motor 12 drives the cross connecting block 132 to rotate, so that the rotating handwheel 5 rotates accordingly, realizing the integration of manual and electric adjustment. Electric adjustment is performed when the power is on normally, and manual adjustment is performed when the power is accidentally cut off, ensuring the use of the flow control valve.

[0046] During manual adjustment, the electric push rod 131 drives the cross connecting block 132 to disengage from the rotating handwheel 5. The operator rotates the rotating handwheel 5, causing the rubber sleeve gear 6 to rotate within the adjustment feedback gear sleeve 7. Since the rubber sleeve gear 6 and the adjustment feedback gear sleeve 7 are slightly meshed, the operator will receive real-time feedback during rotation, which facilitates precise adjustment. At the same time, the scale pointer 10 indicates the reading on the angle scale dial 8, and the flow meter 17 is used to display the flow reading in real time, realizing the visualization and precision of the adjustment process.

[0047] After adjustment, the operator rotates the positioning toothed rod 92 and engages it with the positioning engagement tooth 14 to fix the rotating rod 3, preventing vibration of the medium flow from causing displacement.
