Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, specifically a regulating valve with pressure reduction and noise reduction functions. Background Technology

[0002] Control valves, as key actuators in automatic control systems, play a vital role in industrial production, building facilities, and various fluid transport systems. Based on signals from the control system, they precisely regulate process parameters such as flow rate, pressure, and temperature of fluids (liquids, gases, or steam), ensuring stable and efficient system operation.

[0003] Existing technology publication CN222209223U discloses a regulating valve with noise reduction function, including a base and a regulating valve. A placement platform is slidably connected through the interior of the base. A noise reduction device is installed inside the base. A groove is formed on the inner wall of the base, and a receiving plate is slidably connected to the inner wall of the groove. A first spring is fixed to the bottom end of the receiving plate, and a moving groove is formed at the bottom end of the receiving plate. A second spring is fixed to the inner wall of the moving groove, and a moving block is fixed to the end of the second spring away from the moving groove. A connecting arm is hinged inside the moving block. A fixing block is fixedly connected to the bottom interior of the base. Through the design of the groove, receiving plate, first spring, moving groove, second spring, moving block, connecting arm, fixing block, damping block, and pressing rod, the vibration generated by the regulating valve itself can be reduced during use, thereby reducing noise and effectively increasing the service life of the device.

[0004] However, in the existing control valve, when the medium enters the control valve body through the noise reduction pipe, the medium will pass through three through holes of different sizes opened on the side wall of the flow limiting plate from left to right. The flow rate and pressure of the medium are reduced by passing through the through holes, thereby reducing the noise. However, this method cannot reduce the noise generated by the high pressure differential gas when the fluid passes through. The generated noise will still be transmitted through the control valve, resulting in poor noise reduction effect. Therefore, we propose a control valve with pressure reduction and noise reduction function. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a regulating valve with pressure reduction and noise reduction functions to solve the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a regulating valve with pressure reduction and noise reduction functions, comprising a valve body, a valve pipe integrally connected to the top of the valve body, a valve stem threadedly connected to the top of the valve pipe, a first soundproof cover and a second soundproof cover respectively installed on the outer side of the valve body, soundproof pads installed on the inner sides of both the first and second soundproof covers, a first locking plate fixedly connected to the top and bottom of the first soundproof cover, a locking opening on the front of the first locking plate, a second locking plate fixedly connected to the top and bottom of the second soundproof cover, a locking buckle fixedly connected to the front of the second locking plate, a valve seat fixedly connected inside the valve body, a noise reduction sleeve installed on the top of the valve seat, and a noise reduction port on the outer side of the noise reduction sleeve.

[0009] Preferably, both ends of the valve body are fixedly connected to a mating flange, and a fixing port is provided on one side of the mating flange.

[0010] Preferably, a valve plug is fixedly connected to the bottom end of the valve stem, and the valve plug is movably connected to the noise reduction sleeve.

[0011] Preferably, the sound insulation pad is made of polyester fiber material, and the outer surface of the sound insulation pad is provided with pores.

[0012] Preferably, a handwheel is fixedly connected to the top of the valve stem, and the outer surface of the handwheel is smooth.

[0014] Preferably, multiple noise reduction ports are provided, the multiple noise reduction ports are the same size, and the multiple noise reduction ports are arranged at equal intervals.

[0015] (III) Beneficial Effects

[0016] This utility model provides a regulating valve with pressure reduction and noise reduction functions, which has the following beneficial effects:

[0017] (1) This type of regulating valve with pressure reduction and noise reduction function, through the setting of noise reduction sleeve, first sound insulation cover, second sound insulation cover and sound insulation pad, when using the regulating valve, the operator holds the handwheel and drives the valve stem to rotate clockwise through the handwheel. At this time, the valve stem drives the valve plug to move upward, and the valve plug can move the noise reduction sleeve upward. At the same time, the fluid can flow through the noise reduction port on the noise reduction sleeve. The noise reduction sleeve can play a throttling role by utilizing the noise reduction port. Then the fluid diffuses and expands in the noise reduction sleeve, thereby greatly reducing the noise generated by the high pressure differential gas. The sound is absorbed, and then the fluid flows to the other side through the noise reduction port. When the noise is transmitted through the valve body, it is absorbed by the sound. The valve body is surrounded by the first and second sound insulation covers, and the first and second sound insulation covers are equipped with sound insulation pads. The sound insulation pads are made of polyester fiber material and have a large number of tiny, interconnected pores. When the sound is incident on the surface of the material, some of the sound will enter the pores, causing friction between the air in the pores and the material pore walls, converting the sound energy into heat energy and dissipating it, thereby achieving the effect of sound absorption and sound insulation. Therefore, the pressure reduction and noise reduction effect of the regulating valve is improved. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a regulating valve with pressure reduction and noise reduction function, including a valve body 1, a valve pipe 9 integrally connected to the top of the valve body 1, a valve stem 10 threadedly connected to the top of the valve pipe 9, a first sound insulation cover 4 and a second sound insulation cover 401 respectively installed on the outer side of the valve body 1, sound insulation pads 402 installed on the inner side of both the first sound insulation cover 4 and the second sound insulation cover 401, a first locking plate 5 fixedly connected to the top and bottom of the first sound insulation cover 4, a locking opening 6 opened on the front of the first locking plate 5, a second locking plate 7 fixedly connected to the top and bottom of the second sound insulation cover 401, a locking buckle 8 fixedly connected to the front of the second locking plate 7, a valve seat 13 fixedly connected inside the valve body 1, a noise reduction sleeve 14 installed on the top of the valve seat 13, and a noise reduction port 15 opened on the outer side of the noise reduction sleeve 14.

[0026] Furthermore, both ends of the valve body 1 are fixedly connected to a docking flange 2. A fixing port 3 is opened on one side of the docking flange 2. The docking flange 2 is connected to the pipeline, and then the bolts are inserted into the fixing port 3 of the docking flange 2 for fixing. At this time, the regulating valve can be connected to the pipeline.

[0027] Furthermore, a valve plug 12 is fixedly connected to the bottom end of the valve stem 10. The valve plug 12 is movably connected to the noise reduction sleeve 14. The valve stem 10 is rotated clockwise by the handwheel 11. At this time, the valve stem 10 drives the valve plug 12 to move upward, and the valve plug 12 can move the noise reduction sleeve 14 upward.

[0028] Furthermore, the sound insulation pad 402 is made of polyester fiber material. The outer surface of the sound insulation pad 402 is provided with pores. Because the sound insulation pad 402 is made of polyester fiber material and has a large number of tiny, interconnected pores, when sound is incident on the surface of the material, some of the sound will enter the pores, causing friction between the air in the pores and the pore walls of the material, converting the sound energy into heat energy and dissipating it, thereby achieving the effect of sound absorption and sound insulation.

[0029] Furthermore, a handwheel 11 is fixedly connected to the top of the valve stem 10. The outer surface of the handwheel 11 is smooth, and by holding the handwheel 11, it is easy for the operator to drive the valve stem 10 to rotate.

[0030] Furthermore, the valve body 1 is made of metal and has a hollow structure. The valve body 1, made of metal, is more robust and durable and less prone to damage.

[0031] Furthermore, multiple noise reduction ports 15 are provided, all of the same size, and are arranged at equal intervals. Fluid can flow through the noise reduction ports 15 on the noise reduction sleeve 14. The noise reduction sleeve 14 can throttle the flow by utilizing the noise reduction ports 15. Then, the fluid diffuses and expands within the noise reduction sleeve 14, thereby significantly reducing the noise generated by the high pressure differential gas. Afterward, the fluid flows to the other side through the noise reduction ports 15.

[0032] Working Principle: After installation, first check the installation, fixation, and safety protection of this utility model. When using the regulating valve, the operator connects the connecting flange 2 to the pipeline, and then inserts the bolts into the fixing port 3 of the connecting flange 2 for fixation. At this time, the regulating valve can be connected to the pipeline. Then, the operator holds the handwheel 11 and drives the valve stem 10 to rotate clockwise. At this time, the valve stem 10 drives the valve plug 12 to move upward, and the valve plug 12 can move the noise reduction sleeve 14 upward. At the same time, the fluid can flow through the noise reduction port 15 on the noise reduction sleeve 14. The noise reduction sleeve 14 can play a throttling role by utilizing the noise reduction port 15. Then, the fluid diffuses and expands within the noise reduction sleeve 14. This significantly reduces the noise generated by the high-pressure differential gas. Then, the fluid flows to the other side through the noise reduction port 15. When the noise is transmitted through the valve body 1, it is absorbed by the first sound insulation cover 4 and the second sound insulation cover 401. The first sound insulation cover 4 and the second sound insulation cover 401 are equipped with a sound insulation pad 402. The sound insulation pad 402 is made of polyester fiber material and has a large number of tiny, interconnected pores. When the sound is incident on the surface of the material, some of the sound will enter the pores, causing friction between the air in the pores and the pore walls of the material, converting the sound energy into heat energy and dissipating it, thereby achieving the effect of sound absorption and sound insulation. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
