Problems solved by technology

When eliminating intake noise, sound absorption, sound insulation, and noise reduction methods are generally used to reduce the resonance caused by noise. Reinforcement methods will be used, and measures such as mufflers will be used at the same time. The purpose of noise reduction, but the initial investment needs to be increased, and the later maintenance also needs to be paid attention to, so it is not universal, so we propose a high-efficiency and low-noise compressor inlet valve

Embodiment 1

[0033] see figure 1 , figure 2 as well as image 3 , the high-efficiency and low-noise compressor intake valve of the present invention includes an intake valve plate 01, an intake valve body 03 installed on the intake valve plate 01, and an intake valve control assembly 02 combined with the intake valve body 03 And the silencer assembly 04 connected with the intake valve body 03, the outer side of the intake valve body 03 is provided with a threaded hole 302 for connecting bolts, and is connected with the plate body of the intake valve plate 01 through the threaded hole 302; the intake valve body The top of 03 is also fixedly connected with an extension cylinder, and the outside of the extension cylinder is provided with two symmetrically arranged connecting pipes 301, which communicate with both sides of the intake valve control assembly 02; There is a circular through hole and a bottom positioning column 303 that runs through the intake valve body 03 is plugged into it. ...

Embodiment 2

[0035] see figure 2The inner side of the bottom of the intake valve body 03 is provided with an air outlet through hole 306, and the outer side of the air outlet through hole 306 is located at the inner edge of the intake valve body 03 to be provided with an inner cavity 305, and the inner side of the inner cavity 305 is annularly opened with multiple A card slot 304 provides a stable guarantee for the opening of the card slot 304 by using the inner cavity 305. At the same time, the setting of the card slot 304 can also provide a stable installation position for the sound-absorbing assembly 04. The inner side of the card slot 304 is also clamped with a sealing block. 401, the outer side of the sealing block 401 is connected to the sound-absorbing assembly 04, and the bottom of the sound-absorbing assembly 04 is radially opened with a plurality of air intake through holes with the bottom positioning column 303, and a sound-absorbing plate 403 is fixedly connected to the inner s...

Embodiment 3

[0037] see Figure 4 ,

[0038] The top of the muffler plate 403 is provided with a plurality of air intake passages 402, and the middle part of the air intake passage 402 is curved. Block 406, using the thickened inner wall 407, can force the airflow to pass through without causing the resonance of the intake passage 402, thereby reducing the noise during intake. The airflow can be dispersed, further weakening the resonance effect brought by the airflow.

Abstract

The invention relates to the technical field of compressor air inlet valves, and particularly discloses an efficient low-noise compressor air inlet valve which comprises an air inlet valve plate, an air inlet valve body installed on the air inlet valve plate, an air inlet valve control assembly combined with the air inlet valve body and a silencing assembly connected with the air inlet valve body. A threaded hole connected with a bolt is formed in the outer side of the air inlet valve body, and the air inlet valve body is connected with a plate body of the air inlet valve plate through the threaded hole; an extending cylinder is further fixedly connected to the top of the air inlet valve body, two symmetrically-arranged connecting pipes are arranged on the outer side of the extending cylinder, the arranged silencing assembly can be combined with the air inlet valve body, in the air inlet process, the multiple air inlet channels are arranged and matched with the bent shape, and therefore the silencing effect is improved. And noise generated during air inlet is forced to be counteracted when air flow is bent and conveyed.

Description

technical field [0001] The invention relates to the technical field of compressor intake valves, in particular to a high-efficiency and low-noise compressor intake valve. Background technique [0002] Compressors can provide airflow with stable pressure, which can reduce the problem of airflow pressure fluctuations. At the same time, it has the characteristics of stable rotation and high efficiency. It is a production auxiliary measure for many industrial enterprises and plays an important role in production. [0003] Because the compressor needs to transport air from the outside when it is running, its power is relatively large, and the air transport causes the internal parts to resonate, so the air compressor is a kind of strong noise equipment, and the strong noise generated during operation deteriorates the working conditions and life. surroundings. [0004] The noise is mainly intake noise, exhaust noise, mechanical noise and electromagnetic noise. Intake noise is the...
