[0002] A throttle valve is a valve that controls fluid flow and pressure by changing the cross-sectional area of ​​the channel. It mainly achieves the purpose of regulating flow by changing the gap between the valve core and the valve seat, thereby changing the cross-sectional area of ​​the channel through which the fluid passes through the valve. The throttle valve produces relatively loud noise during operation and requires noise reduction treatment using noise reduction components.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figure 1-Figure 7 The utility model provides an embodiment: a noise reduction throttle valve assembly, including a base 1, and also including a slide plate 21, a mounting plate 22, a spring 23, a damper 24 and a mounting mechanism. The base 1 is provided with a mounting mechanism inside. The base 1 is slidably connected with the slide plate 21 inside, and the inner side of the slide plate 21 is fixedly connected with the mounting plate 22. The spring 23 is fixedly connected between the mounting plate 22 and the base 1, and the damper 24 is fixedly connected between the mounting plate 22 and the base 1. The spring 23 and the damper 24 absorb the vibration generated by the impact to prevent shaking. The one-way screw 46 can be raised and lowered by twisting the second nut 45, and the sealing ring 411 can play a sealing effect to prevent leakage at the connection between the connecting rod 47 and the throttle valve body 41. The one-way screw 46 can be raised and lowered to adjust the relative position of the valve core 49 and the valve seat 43, thereby controlling the flow rate. The throttle valve body 41 is removable through the support frame 25 and the fixing frame 28, and the throttle valve body 41 is disassembled, replaced and repaired. The vibration caused by the impact is absorbed by the spring 23 and the damping 24 to prevent the throttle valve body 41 from shaking and generating noise.

The slide plate 21 and the mounting plate 22 are limited by the slide grooves so that the slide plate 21 and the mounting plate 22 can only slide up and down in a straight line and will not fall out of the slide grooves.

[0023] See also Figures 1-4In this embodiment, the top of the mounting plate 22 is fixedly connected to a support frame 25, and the top of the support frame 25 is fixedly connected to a slot plate 26. The interior of the slot plate 26 is movably connected to a slide rod 27, and the exterior of the slide rod 27 is fixedly connected to a fixing frame 28. Bolts 29 are provided inside the fixing frame 28 and the support frame 25. The exterior of the bolt 29 is threadedly connected to a first nut 210. The position of the throttle valve body 41 can be installed by cooperating with the support frame 25 and the fixing frame 28, and the fixing frame 28 can be opened to take out the throttle valve body 41, which is convenient for inspecting the throttle valve body 41. The slot plate 26 is provided with a limiting groove at the corresponding position of the slide rod 27, and the slide rod 27 is movably connected to the inside of the limiting groove. The position of the fixing frame 28 is positioned by the slot plate 26, so that the fixing frame 28 is more flexible, and the fixation of the throttle valve body 41 is more convenient, thereby preventing position conflict with the throttle valve body 41.

[0024] See also Figure 1 、 Figure 5 In this embodiment, the mounting mechanism includes an external hexagonal rotating rod 31, which is rotatably connected to the inside of the base 1, and a bidirectional screw 32 is fixedly connected to the inner side of the external hexagonal rotating rod 31. The external thread of the bidirectional screw 32 is connected to a slider 33, and the outer side of the slider 33 is fixedly connected to a fixing ear 34. The positions of the two fixing ears 34 are synchronously adjusted by rotating the bidirectional screw 32, so that the fixing ears 34 correspond to the appropriate positions for fixation, which can be applied to different installation positions. There are four sliders 33, and the base 1 is provided with sliding grooves at the corresponding positions of the four sliders 33, and the four sliders 33 slide symmetrically inside the sliding grooves. The sliders 33 are limited by the sliding grooves so that the sliders 33 can only slide linearly inside the sliding grooves and cannot rotate, so that the sliders 33 can be driven to move by the bidirectional screws 32.

[0025] See also Figure 1 、 Figure 6 、 Figure 7In this embodiment, a throttle valve further includes a throttle valve body 41, which is arranged inside the support frame 25 and the fixing frame 28. The left and right sides of the throttle valve body 41 are fixedly connected with flanges 42. The interior of the throttle valve body 41 is fixedly connected with a valve seat 43. The interior of the throttle valve body 41 is fixedly connected with a sealing ring 411. The top of the throttle valve body 41 is fixedly connected with a positioning frame 44. The interior of the positioning frame 44 is rotatably connected with a second nut 45. The interior of the second nut 45 is threadedly connected with a one-way screw 46. The bottom of the one-way screw 46 is fixedly connected with a connecting rod 47. The connecting rod 47 is provided It is located inside the throttle valve body 41, and the connecting rod 47 is arranged inside the sealing ring 411. The bottom of the connecting rod 47 is fixedly connected to the rotating disk 48. The inside of the throttle valve body 41 is slidingly connected to the positioning plate 410. The bottom of the positioning plate 410 is fixedly connected to the valve core 49. The rotating disk 48 is rotatably connected to the inside of the valve core 49. The valve core 49 is arranged inside the valve seat 43. By twisting the second nut 45 to drive the one-way screw 46, the distance between the valve core 49 and the valve seat 43 can be controlled to control the flow rate. The valve core 49 corresponds to the shape and size of the valve seat 43, the flow control is more precise, and the blocking effect is better when closed.

[0026] During operation, the corresponding pipeline is connected through the flange 42 to allow the liquid to enter the cavity of the throttle valve body 41, and the second nut 45 is twisted to drive the one-way screw 46, and the one-way screw 46 drives the connecting rod 47. The connecting rod 47 drives the valve core 49 through the rotating disk 48. The valve core 49 slides inside the throttle valve body 41 through the positioning plate 410, and the distance between the valve core 49 and the valve seat 43 is adjusted to control the flow rate. When the throttle valve body 41 is impacted by the water flow, the impact force is transmitted to the mounting plate 22 through the fixing frame 28 and the supporting frame 25. The mounting plate 22 compresses the spring 23 and the damping 24, and the impact is absorbed by the spring 23 and the damping 24. The nut 210 is disengaged from the bolt 29, and the bolt 29 is removed from the inside of the fixing frame 28 and the support frame 25, so that the fixing frame 28 is freed from its restraint. The fixing frame 28 is first pushed upward, and the fixing frame 28 drives the slide bar 27 to slide inside the limit groove of the slot plate 26, so that the fixing frame 28 is raised to the highest point. Then the fixing frame 28 is rotated to open, and the throttle valve body 41 can be taken out from the inside of the support frame 25. The outer hexagonal rotating rod 31 is twisted to drive the two-way screw 32, and the two-way screw 32 drives the slider 33. The slider 33 drives the fixing ear 34, and the position of the fixing ear 34 is adjusted so that the fixing ear 34 corresponds to the appropriate mounting hole position, thereby fixing the position of the base 1 through the fixing ear 34.

[0027] Through the above steps, the mounting plate 22 absorbs the impact through the spring 23 and the damper 24, thereby preventing the throttle valve body 41 from shaking, thereby solving the problem that unstable water flow may cause the throttle valve to shake, thereby generating noise and causing noise pollution to the working environment.
