The utility model provides a low-frequency resonance suppression front wall sound insulation pad, which relates to the technical field of sound insulation pads and comprises a sound insulation pad main body, and a base material framework layer is arranged in the sound insulation pad main body. According to the utility model, the low-frequency sound absorption layer is made of the open-cell polyurethane foam, and residual low-frequency noise penetrating through the dash panel is treated through friction loss of a porous material or sound energy absorption of the resonant cavity. The mass load layer is made of a high-density PVC plate, the overall mass of the sound insulation pad is increased, the blocking capacity to low-frequency sound waves is improved, the damping vibration attenuation layer is made of asphalt-based damping fins, when the sound insulation pad body is subjected to low-frequency vibration, the materials can convert vibration energy into heat energy and other forms of energy to be dissipated, and therefore the vibration amplitude is reduced, and the sound insulation pad has the good sound insulation effect. And low-frequency noise generated by vibration is reduced. And by arranging the low-frequency sound absorption layer, the mass load layer and the damping vibration attenuation layer, the low-frequency sound wave blocking capacity of the sound insulation pad body is effectively improved.

A valve device
A valve device includes a valve seat assembly and a valve core. The valve seat assembly has a valve cavity, and the valve core is rotatable within the valve cavity. The valve seat assembly also has a first opening, a second opening, and a third opening, with the first and second openings spaced apart around the rotation direction of the valve core. The valve core has a valve core channel, and the third opening communicates with the valve core channel. The valve core channel includes a valve core opening, and both the first and second openings communicate with the same valve core opening. The valve device includes a flow-diverting state, in which the first and second openings communicate with the same valve core opening. This configuration helps to reduce flow resistance during the operation of the valve device.
