Description

Technical Field

[0001] This utility model relates to the field of control valve technology, and in particular to a shock-absorbing and noise-reducing safe flow control valve. Background Technology

[0002] In hydraulic systems, flow control valves are one of the key components used to regulate the flow rate of liquid to meet the system's operational requirements.

[0003] However, traditional flow control valves often generate vibration and noise during operation, which not only affects the normal operation of the system but may also cause noise pollution to the surrounding environment. In addition, when the system pressure is too high, traditional flow control valves may not be able to provide timely and effective safety protection, posing certain safety hazards.

[0004] Therefore, we propose a shock-absorbing and noise-reducing safe flow control valve. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a shock-absorbing and noise-reducing safe flow control valve, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing and noise-reducing safety flow control valve, comprising a valve body, an inlet pipe and an outlet pipe respectively provided on both sides of the valve body, a mounting block provided on the top of the valve body, an electric telescopic mechanism provided on the mounting block, an end of the electric telescopic mechanism extending into the interior of the valve body and fitted with a plug, a fixing block provided inside the valve body, a through groove provided in the middle of the fixing block, connecting pipes provided on the upper and lower sides of the fixing block near the through groove, the other end of the connecting pipe extending to the upper surface of the fixing block and provided with an outlet, a diversion pipe provided at the bottom of the valve body, a water outlet fixedly connected to the middle of the diversion pipe, and an extension pipe provided at the bottom of the valve body.

[0007] In a preferred embodiment, the present invention can be further configured such that: the extension tube is bent and the other end of the extension tube extends to below the plug; a connecting block is provided at the top of the extension tube; a rotating cover plate is rotatably provided on the connecting block; and the rotating cover plate is adapted to the extension tube.

[0008] In a preferred embodiment, the present invention can be further configured such that: a drive motor is provided below the fixed block of the valve body, a connecting rope is sleeved on the output shaft of the drive motor, and the connecting rope is fixedly connected to the rotating cover plate.

[0009] In a preferred embodiment, the present invention can be further configured such that: the diversion pipe is connected to the extension pipe, and through holes are provided in both the diversion pipe and the extension pipe; a movable column is slidably arranged inside the diversion pipe; and a spring is provided at the bottom of the diversion pipe, and the spring is fixedly connected to the movable column.

[0010] In a preferred embodiment, the present invention can be further configured such that the diversion pipe is connected to the outlet, and a one-way valve is fixedly installed between the outlet and the diversion pipe.

[0011] In a preferred embodiment, the present invention can be further configured such that: a damping layer is provided inside the valve body, a damper and sound-absorbing cotton are provided inside the damping layer, and a noise-reducing coating is applied to the outside of the valve body.

[0012] The beneficial effects of this utility model are:

[0013] This utility model incorporates an electric telescopic mechanism that moves the plug up and down, thereby opening the connecting pipe and the outlet sequentially from bottom to top. This facilitates graded control. When a large flow rate is required, the plug can be disengaged from the fixed block to fully open the channel and allow for a large flow of water.

[0014] By setting up a shock-absorbing layer and applying a noise-reducing coating, the overall sound insulation and noise reduction of the valve body are increased;

[0015] The drive motor rotates, which in turn winds up the connecting rope, causing the connecting rope to open the rotating cover. Excess fluid enters the diversion pipe through the extension pipe. When the system pressure exceeds the set value, the movable column overcomes the spring force under pressure, opens the pressure relief port, and discharges the excess fluid, thereby reducing the system pressure.

[0024] 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.

[0025] In the embodiments

[0026] Please see Figures 1-7 A shock-absorbing and noise-reducing safety flow control valve includes a valve body 1. An inlet pipe 2 and an outlet pipe 3 are respectively provided on both sides of the valve body 1. An installation block 4 is provided on the top of the valve body 1. An electric telescopic mechanism 5 is provided on the installation block 4. The end of the electric telescopic mechanism 5 extends into the interior of the valve body 1 and is fitted with a plug 11. A fixing block 10 is provided inside the valve body 1. A through groove is opened in the middle of the fixing block 10. Connecting pipes 9 are opened at the top and bottom on the side of the fixing block 10 near the through groove. The other end of the connecting pipe 9 extends to the upper surface of the fixing block 10 and is provided with an outlet 6. A diversion pipe 7 is provided at the bottom of the valve body 1. An outlet 8 is fixedly connected to the middle of the diversion pipe 7. An extension pipe 14 is provided at the bottom of the valve body 1.

[0027] The extension tube 14 is bent, and its other end extends to below the plug 11. A connecting block 15 is provided at the top of the extension tube 14, and a rotating cover plate 16 is rotatably mounted on the connecting block 15, which is adapted to the extension tube 14. A drive motor 12 is also provided below the fixing block 10 in the valve body 1. A connecting rope 13 is sleeved on the output shaft of the drive motor 12, and the connecting rope 13 is fixedly connected to the rotating cover plate 16.

[0028] The diversion pipe 7 is connected to the extension pipe 14, and both the diversion pipe 7 and the extension pipe 14 have through holes 17. A movable column 18 is slidably installed inside the diversion pipe 7, and a spring 19 is installed at the bottom of the diversion pipe 7, and is fixedly connected to the movable column 18 through the spring 19. The diversion pipe 7 is connected to the outlet 8, and a one-way valve is fixedly installed between the outlet 8 and the diversion pipe 7.

[0029] The valve body 1 is provided with a damping layer 20, and the damping layer 20 is provided with a damper and sound-absorbing cotton inside. The valve body 1 is coated with a noise-reducing coating.

[0030] See again Figure 7 Fluid enters the valve body 1 through the inlet pipe 2 and flows towards the fixed block 10. The fluid is blocked by the fixed block 10, causing it to flow back and then towards the extension pipe 14. The drive motor 12 drives the connecting rope 13 to wind up, which in turn drives the rotating cover 16 fixedly connected to the connecting rope 13 to open. When the connecting rope 13 is taut, the opening of the extension pipe 14 is opened to the maximum, and the rotating cover 16 rotates at an angle of 0-45°. When the water pressure is not so high, the drive motor 12 rotates back, causing the connecting rope 13 to loosen. The water pressure drives the rotating cover 16 to close the extension pipe 14, shutting off the extension pipe 14.

[0031] Working principle: When this device is in use, liquid enters through the inlet pipe 2 and exits through the outlet pipe 3. The fixed block 10 completely divides the inside of the valve body 1 into two spaces of equal size. The electric telescopic mechanism 5 drives the plug 11 to move up and down, thereby adjusting the flow rate at the outlet. The fluid enters the connecting pipe 9 from bottom to top and is output through different outlets 6. When the flow rate is large, the electric telescopic mechanism 5 drives the plug 11 to completely separate from the fixed block 10, so that the fluid can flow out from the through groove.

[0032] When a safe flow rate is set, if the system pressure exceeds the set value, the drive motor 12 will operate, causing the connecting rope 13 to wind up. This will cause the rotating cover 16, which is fixedly connected to the other end of the connecting rope 13, to be subjected to a corresponding force, causing the rotating cover 16 to open. The fluid will then enter the diversion pipe 7 through the extension pipe 14. By squeezing the movable column 18, which is in contact with the through hole 17, the fluid will move downward, squeezing the spring 19. This will cause the movable column 18 to move to the outlet 8 side, and the excess fluid will be discharged through the outlet 8, thereby reducing the system pressure and ensuring the safe operation of the system.
