Description
Technical field
The utility model is related to marine engine device field, especially a kind of marine engine noise elimination gas handling system.
Background technology
Its cardinal principle of marine engine muffler is to reduce noise using sound-absorbing porous material.Sound-absorbing material is fixed
It is arranged in the duct on the inner wall of the gas channel of inlet manifold or according to certain way, just constitutes resistive muffler.When
When sound wave enters dissipative muffler, a part of acoustic energy rubs in the hole of porous material and is converted to thermal energy consumption and dissipates, and makes to lead to
The sound wave for crossing silencer weakens.Resistive muffler device just looks like pure resistor element circuit electrically, and sound-absorbing material is similar to resistance.Cause
This, this silencer is just called dissipative muffler by people.Dissipative muffler is good to medium-high frequency noise elimination effect, eliminates the noise and imitates to low frequency
Fruit is poor.
Usually there are one idling air control valves for the internal combustion engine of marine engine, when the choke block of engine is closed or is approached
When closing, for adjusting the air into motor intake manifold.The air inlet pipe of idling air control valve is connected to air pipeline,
Escape pipe is connect with engine charge room.
Space is small in idling air control valve installation site, above-mentioned not to be suitable for idling using the noise-reducing structure of sound-absorbing material
The noise reduction of air control valve is handled.Through retrieval, currently without the marine engine gas handling system idling air conditioning being easily installed
Valve noise-reducing structure.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of easy for installation, at low cost, applicability
Good marine engine noise elimination gas handling system.
The utility model solves its technical problem and is achieved through the following technical solutions：
A kind of marine engine noise elimination gas handling system, including ventilation shaft, throttle valve and idle air control valve, are divulging information
Throttle valve is installed on pipeline, choke block is installed in throttle valve, idle air control valve, idling air are installed on ventilation shaft
The air inlet of control valve is connected to the air inlet side of throttle valve by admission line, and gas outlet is connected to throttling by outlet pipe
Valve goes out gas side, it is characterised in that：Noise reduction valve is installed on the air inlet of the idle air control valve, which includes expansion
Room, expanding chamber are formed with expanding chamber air inlet and expanding chamber gas outlet, the air inlet pipe of expanding chamber air inlet and idle air control valve
Road connects, and the air inlet of expanding chamber gas outlet and idle air control valve connects；The expanding chamber air inlet and expanding chamber outlet
The axis parallel interval of mouth.
Moreover, the expanding chamber air inlet is sleeve shaped air inlet, sleeve shaped air inlet is connect with admission line.
Moreover, the expanding chamber gas outlet is sleeve shaped gas outlet, sleeve shaped gas outlet and idle air control valve into
Gas port coaxial package.
It the advantages of the utility model and has the beneficial effect that：
1, the marine engine noise elimination gas handling system of the utility model, by pacifying on the air inlet of idle air control valve
Noise reduction valve is filled, which includes expanding chamber, and expanding chamber is formed with expanding chamber air inlet and expanding chamber gas outlet, expanding chamber air inlet
It is connect with the admission line of idle air control valve, the air inlet connection of expanding chamber gas outlet and idle air control valve passes through
Gas enters expanding chamber and it is made to realize the decaying of noise；And parallel with the axis of expanding chamber gas outlet of expanding chamber air inlet
Every increase gas die-away time in expanding chamber improves noise reduction effect.
2, the marine engine noise elimination gas handling system of the utility model, expanding chamber air inlet and gas outlet are sleeve shaped,
It conveniently carries out installation with admission line and the air inlet of idle air control valve to connect, installation is extremely easy.
3, the utility model scientific structure design realizes noise reduction rationally, it can be achieved that with engine aspirating system Fast Installation
Noise reduction effect, and it is simple in structure, it is readily produced manufacture, at low cost, it can be achieved that modularization is installed, being one kind having higher innovation
Marine engine noise elimination gas handling system.

Specific implementation mode
Below by specific embodiment, the utility model is described in further detail, following embodiment be it is descriptive, no
It is restrictive, protection scope of this utility model cannot be limited by this.
A kind of marine engine noise elimination gas handling system, including ventilation shaft 1, throttle valve 2 and idle air control valve 7,
Throttle valve is installed on ventilation shaft, choke block 3 is installed in throttle valve, idle air control valve is installed on ventilation shaft, it is idle
Fast air shut-off valve air inlet 11 is connected to the air inlet side of throttle valve by admission line 4, and idle air control valve gas outlet 6 connects
