Embodiment 1

[0026] Embodiment 1: as figure 1 , figure 2 A compressor cylinder head with noise reduction function shown includes a cylinder head body 1 and a muffler arranged on one side of the cylinder head body. The muffler is composed of a muffler body 8, a muffler cover 4 arranged on the end face of the muffler body and a sealing gasket 3 arranged between the muffler body and the muffler cover. The muffler body 8 and the cylinder head body 1 are integrally cast. The muffler is provided with a muffler cavity 5, specifically, a recessed cavity is provided on the end face of the muffler body 8 that cooperates with the muffler cover 4, and the muffler cavity 5 is formed by the gap between the muffler body and the muffler cover. The concave cavity is formed. The muffler cavity 5 is divided into a first cavity 51 and a second cavity 52 by a partition 6; specifically, a partition 6 is provided in the recessed cavity, and the partition 6 is in contact with the end face of the muffler body ...

Embodiment 2

[0030] Embodiment 2: the remaining structure of this embodiment is with reference to embodiment 1, and its difference is:

[0031] Such as image 3 As shown, the partition plate 6 is also provided with a third vent hole 24 communicating with the first cavity 51 and the second cavity 52, and the cylinder head body 1 is also provided with a third vent hole 24 communicating with the second cavity 52 and the air guide groove 2. Four ventilation holes 18. The cross sections of the first vent hole 7 , the second vent hole 11 and the third vent hole 24 are all circular. The first vent hole 7 is opposite to the second vent hole 11 . The first air hole, the second air hole and the third air hole are respectively provided with electromagnetic valves 12a, 12b, 12c or electric valves for controlling the opening and closing of the air holes. The solenoid valve or electric valve used to control the first vent hole and the third vent hole is located in the first cavity, and one port of th...

Abstract

The invention discloses a compressor cylinder head with a noise elimination function, and aims to provide a compressor cylinder head which is capable of effectively reducing the production cost, is provided with a compact structure, and has a good noise elimination effect. The compressor cylinder head comprises a cylinder head body and a silencer arranged on one side of the cylinder head body, a noise elimination cavity is arranged in the silencer, and is divided into a first cavity and a second cavity by a baffle, the side face of the silencer is provided with an air suction port communicated with the first cavity, the baffle is provided with a first ventilation hole which communicates the first cavity with the second cavity, an air guide slot is arranged on one side, close to the silencer, of the end face of the cylinder head body, the cylinder head body is further provided with a second ventilation hole which communicates the second cavity with the air guide slot, the silencer is composed of a silencer body, a silencer cover body and a sealing gasket arranged between the silencer body and the silencer cover body, and the silencer body and the silencer cover body are integrally cast and formed.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a compressor cylinder head with a sound-absorbing function. Background technique [0002] Noise has been regarded as one of the serious pollution in the world today, and the noise problem of the compressor has become an important indicator to measure its comprehensive performance. The main noise source of the compressor is composed of three parts: the aerodynamic noise radiated by the intake and exhaust, the mechanical noise generated by the mechanical moving parts, and the noise of the driving motor; and the exhaust noise is weaker than the intake noise, so the aerodynamic performance of the compressor The noise is generally dominated by intake noise. [0003] Compressors usually reduce noise by setting intake and exhaust mufflers, and the muffler in the compressor is generally a resistance muffler; it causes a change in impedance during sound propagation through a sudden change in t...
