Quick opening-closing pneumatic system of gas-saving low-noise valve

Abstract

The invention relates to a quick opening-closing pneumatic system of a gas-saving low-noise valve. One branches of an air inlet and an air outlet of a cylinder rodless cavity are connected with an air source through a first throttling valve and a two-position five-way electromagnetic reversing valve A or communicated with a silencer through the first throttling valve, the two-position five-way electromagnetic reversing valve A and a first one-way valve, the other branches of the air inlet and the air outlet of the cylinder rodless cavity are communicated with the silencer through a fourth one-way valve and a two-position five-way electromagnetic reversing valve B, one branches of an air inlet and an air outlet of a cylinder rod-having cavity are communicated with the silencer through a third one-way valve and the two-position five-way electromagnetic reversing valve A, and the other branches of the air inlet and the air outlet of the cylinder rod-having cavity are connected with the air source through a second throttling valve and the two-position five-way electromagnetic reversing valve B or communicated with the silencer through the second throttling valve, the two-position five-way electromagnetic reversing valve B and a second one-way valve. The quick opening-closing pneumatic system is low in requirement on transient air supply quantity, air consumption quantity is reduced greatly when compared with that of a conventional system, air noise is lowered greatly, using requirements on ship environment are met, and the quick opening-closing pneumatic system is high in integration level, high in reliability and convenient to mount.

Description

technical field [0001] The invention relates to a switch pneumatic system dedicated to an air valve control type passive anti-rolling water tank device, in particular to a pneumatic system capable of quickly switching multiple pneumatic valves at the same time under the condition that the instantaneous air supply capacity of an air source is limited. Background technique [0002] The pneumatic valves of the air valve-controlled passive anti-rolling water tank device are used to adjust the oscillation phase of the water level in the tank. The number of valves is usually large (generally 6~16) and requires rapid opening and closing. The conventional pneumatic valve control system adopts a simple single reversing valve control method, which requires the gas source to have a very large instantaneous gas supply capacity to meet the requirements of rapid opening and closing of multiple valves in the system. The device is discharged instantaneously, and the air noise is very loud. ...

AI Technical Summary

Problems solved by technology

Excessive air consumption of marine equipment will cause the air compressor to start frequently, affecting the service life of the air compressor, and may affect the normal operation of the main engine in serious cases

Moreover, modern ships pay more and more attention to noise control, so the air consumption and air noise become important factors affecting the suitability of the valve-controlled passive anti-rolling water tank device
