[0050] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a low-noise silenced reversing valve.

[0051] A low-noise silencer directional control valve includes a valve body 1 and a valve core 10, the valve core 10 being disposed within the valve body 1. It also includes a noise reduction mechanism disposed on the valve body 1 for noise reduction operations. The noise reduction mechanism includes: a noise reduction box 2 disposed within the valve body 1 and fixedly connected to it; multiple noise reduction springs 3 disposed within and fixedly connected to the noise reduction box 2; multiple noise reduction plates 4 disposed within and fixedly connected to the noise reduction box 2; multiple connectors 5 disposed on the valve body 1 for connecting external pipes; multiple noise reduction cylinders 6 disposed on and fixedly connected to the connectors 5; and an installation mechanism disposed on the valve body 1 for installing the valve body 1 and for noise reduction.

[0052] refer to Figure 1 and Figure 2 In a preferred embodiment, the noise reduction mechanism further includes: two working ports 7, which are disposed within the valve body 1 for hydraulic oil flow; a pressure port 8, disposed within the valve body 1 for applying pressure; and a return port 9, disposed within the valve body 1 for hydraulic oil return.

[0053] With this configuration, both the noise reduction plate 4 and the noise reduction cylinder 6 are porous structures, enabling effective noise reduction. The noise reduction box 2 is made of fiberglass, which effectively absorbs noise, allowing the noise to enter the interior of the noise reduction box 2 and then be reduced again by the noise reduction spring 3 and the lowering plate, thus achieving effective noise reduction.

[0054] refer to Figure 1 and Figure 5 In a preferred embodiment, the installation mechanism includes: a protective part disposed on the valve body 1 for protecting the valve body 1; a noise reduction buffer part disposed on the protective part for noise reduction and buffering; and two mounting parts disposed on the noise reduction buffer part for installing and fixing the reversing valve.

[0055] refer to Figure 3 In a preferred embodiment, the protective part includes: a first protective shell 11 disposed on the valve body 1 for protecting the valve body 1; a second protective shell 12 disposed on the valve body 1 for protecting the valve body 1; and multiple connecting holes 13 disposed on the first protective shell 11 and the second protective shell 12 for connecting the first protective shell 11 and the second protective shell 12.

[0056] refer to Figure 3In a preferred embodiment, the noise reduction buffer includes: a buffer pad 14, which is respectively disposed on the first protective shell 11 and the second protective shell 12 for buffering operation; two buffer springs 15, which are disposed on the first protective shell 11 and fixedly connected to the first protective shell 11; and multiple fixing holes 16, which are disposed on the first protective shell 11 for component installation.

[0057] refer to Figure 3 and Figure 5 In a preferred embodiment, the mounting part includes: a mounting plate 17 disposed on the buffer spring 15 and fixedly connected to the buffer spring 15; a fixing ring 18 disposed on the mounting plate 17 and fixedly connected to the mounting plate 17; multiple fixing posts 19 disposed on the mounting plate 17 and fixedly connected to the mounting plate 17; and multiple mounting holes 20 disposed on the mounting plate 17 for fixing the reversing valve.

[0058] With this configuration, the buffer pad 14 is used so that when the buffer spring 15 is working, the mounting plate 17 will contact the buffer pad 14 for further buffering, preventing excessive noise; the fixing ring 18 is used to prevent the mounting plate 17 from moving arbitrarily; the fixing post 19 can slide within the fixing hole 16, which also ensures the vertical movement of the mounting plate 17 and prevents the mounting plate 17 from moving arbitrarily.

[0059] This device, by incorporating a noise reduction mechanism, can directly reduce the noise generated during the operation of the directional valve. It can also reduce noise at external locations, preventing noise generation. Furthermore, the device's mounting mechanism, once installed and secured, absorbs and buffers vibrations generated during the valve's operation, preventing excessive noise from the device and its mounting location, thus further reducing noise.

[0060] Working principle: When using this device, the fixing bolts are used to fix the device in the required position through the mounting holes 20. Then, the external pipe is connected through the connector 5 to start working. During the operation, the noise reduction cylinder 6 can reduce noise at the pipe connection position. The noise generated during operation is reduced by the noise reduction box 2. The noise reduction plate 4 in the noise reduction box 2 has multiple holes to silence the noise, thus achieving the noise reduction work. At the same time, the noise reduction spring 3 and the noise reduction plate 4 also provide support. Meanwhile, if the reversing valve vibrates during operation, it can be buffered by the buffer pad 14 and the buffer spring 15, thereby preventing a lot of noise from the device and the connection position, thus achieving the noise reduction work.

[0061] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
