Preferably, there are at least three arc-shaped reeds arranged in an annular array.

Preferably, when the arc-shaped reeds are odd in number, they are symmetrically arranged in pairs, wherein the symmetrically arranged bottom sheets of the reeds are connected together with the circular valve sheet, and the installation holes and the small holes are combined together, The extra arc-shaped reed is connected with the circular valve piece alone, and the inner side of the circular valve piece is located between the arc-shaped ends, and a raised arc piece connected as a whole is provided on the raised arc piece. hole.

Preferably, when the arc-shaped reeds are even-numbered, they are symmetrically arranged in pairs, wherein the bottom pieces of the symmetrically arranged reeds are connected together with the circular valve piece, and the installation holes and the small holes are combined together.

Preferably, the arc-shaped reeds are arranged so that the arc-shaped end is connected end-to-end with the reed base, and each of the reed bases is provided with a mounting hole and a small hole.

Preferably, a reed gap is formed between the arc-shaped reed and the circular valve plate.

Preferably, the connection between the reed bottom plate and the circular valve plate is arc-shaped and smoothly connected with the arc-shaped arm.

Compared with the traditional technology, the beneficial effect of the present invention is: the present invention balances the gas pressure on the valve plate by setting multiple sets of arc-shaped reeds, and directly sets the arc-shaped reeds in the large through hole to reduce the gas pressure. The impact force on the circular valve plate improves the service life, and reduces the bending force of the reed to reduce energy consumption.
