Embodiment Construction

[0023] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments, and it should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention.

[0024] A kind of elastic plate type straight-through perforated pipe water muffler with static pressure balance chamber, such as figure 1 , 2 As shown, it includes a flange 1, a muffler main pipe 2, an elastic sheet 5, an expansion chamber housing 6, a balance chamber housing 7, a balance chamber sealing plate 8, and a sealing rubber ring 11.

[0025] The expansion chamber housing 6 is coaxially connected with the balance chamber housing 7 to form a muffler housing. The other end of the balance chamber housing 7 is connected to the balance chamber sealing plate 8. The main pipe 2 of the muffler passes through the expansion chamber from one end of the expansion chamber housing 6 in...

Abstract

The invention discloses an elastic plate type straight-through perforated pipe water silencer with a static pressure balance cavity. The silencer perforates a main pipeline in an expansion cavity, and the aperture is small; one end of the expansion cavity is a rigid wall surface and the other end is an elastic thin plate; when no sound pressure is transmitted in the pipeline, the air pressure of the static pressure balance cavity and the water pressure of the expansion cavity are kept balanced, and the elastic thin plate is in a balanced state; the elastic thin plate makes micro elastic movement under the action of sound pressure, and the vibration direction of the elastic plate is always opposite to the movement direction of the mainstream water medium under the action of sound waves, namely, a counteracting sound source is formed. The invention further provides an assembling method. The silencer does not need to be large in size, the silencer further has the silencing characteristic of a straight-through perforated pipe silencer, and the silencing effect of the silencer is further improved on the premise that the requirement for low flow resistance of a pipeline is met.

Description

technical field [0001] The invention relates to a muffler, in particular to an elastic plate type straight-through perforated pipe water muffler with a static pressure balance chamber and an assembly method. Background technique [0002] The water inlet and outlet pipes of the seawater pipeline system on the ship are directly connected with seawater. During the working process of the system, due to the shape, size and layout of pumps, valves and pipelines, pressure pulsations will occur in the water medium. Pressure pulsation will not only cause pipeline vibration, but also affect pipeline safety, and even have a greater impact on people's lives; pumps, valves and other components in water pipeline systems are the main noise sources, and their noise energy is mainly concentrated in low and medium frequency bands. The noise radiates directly into the seawater through the nozzle, and the transmission distance is long and the efficiency is high, causing serious radiation noise,...
