Description
Technical field
A kind of natural gas distribution piping is the utility model is related to, belongs to natural gas engine or dual fuel engine distribution
Pipe device field.
Background technology
With the rapid development of the industry such as automobile, ship, petroleum resources shortage and the problem of increasing environmental pollution it is increasingly convex
It is aobvious, force people to accelerate research and development and the application process of Engine Alternative Fuel.Natural gas is due to exhaust emission is low, resource
The advantages that abundant, cheap, therefore turn into a kind of extremely potential substitute fuel.At present, natural gas engine and double
Engine fuel is more and more paid close attention to its preferable dynamic property, economy, emission performance by market.Natural gas engine changes
The quality that gas process is carried out, is directly affected to engine performance, and engine aspirating system and port timing are to influence hair
The principal element of motivation scavenging period quality, but the natural gas air inlet pipe system of these engines substantially uses straight tube at present
Each cylinder head is connected to as house steward, then by each cylinder branch pipe, this mode is simple in construction, is easily installed, but exists
The problem of be that can cause " to rob gas " between each cylinder, cause each cylinder natural gas air inflow uneven, finally make each gas of engine
Cylinder work done is uneven, reduces the service life of engine.
Utility model content
The purpose of this utility model is to propose a kind of natural gas distribution piping, and the natural gas distribution piping makes engine each
The air inflow uniformity of cylinder, make each cylinder work done of engine uniform, extend the service life of engine.
Natural gas distribution piping described in the utility model, installed with engine, including house steward, distribution header one and distribution
House steward two, and distribution header one and distribution header two are connected with the cylinder branch pipe of identical quantity, and each cylinder branch pipe connects engine respectively
Each cylinder, and cylinder adjacent with work done order connection cylinder branch pipe connect distribution header one and distribution header two respectively；House steward
Distribution header one and distribution header two are connected respectively by two dispensing branch.
Each cylinder is entered by distribution header one and distribution header two respectively after house steward's air inlet, and it is adjacent with work done order
The cylinder branch pipe of cylinder connection connects distribution header one and distribution header two respectively, therefore two cylinders of adjacent air inlet acting separate, and increase
The off time of air inlet between two cylinders, air inlet interference is alleviated, be advantageous to be lifted the air inflow of each cylinder natural gas, it is final real
Each cylinder intake of existing engine is uniform, extends the service life of engine.
Preferably, the middle section position of described dispensing branch is flexible pipe.Each cylinder of engine is by an original house steward
Connection control, is changed to two distribution pipes while connects control, so if each pipe somewhat error, is assembled then more tired during installation
Difficulty, therefore install flexible pipe additional, the assembling of convenient whole distribution piping and engine is installed.
Preferably, two described dispensing branch are connected to the middle section position of distribution header one and distribution header two.
Preferably, between described house steward and dispensing branch, between dispensing branch and distribution header one and distribution header two
Connected by flange, cylinder branch pipe is fixedly connected by welding with distribution header one and distribution header two.
Possessed beneficial effect is the utility model compared with prior art：
The utility model is reasonable in design, and natural gas inlet manifold is divided into two, distribution header one and distribution header
Two respectively connect the cylinder of engine half by each cylinder branch pipe, due to the work of the cylinder in distribution header one and distribution header two
Work(order is non-conterminous, and this will be significantly reduced " robbing gas problem " of adjacent each cylinder, finally make the natural gas of each cylinder of engine
Air inflow uniformity, make each cylinder work done of engine uniform, extend the service life of engine.

Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
Such as Fig. 1 and Fig. 2, natural gas distribution piping described in the utility model, installed with engine, including house steward 2, distribution
House steward 1 and distribution header 24, distribution header 1 and distribution header 24 are connected with the cylinder branch pipe of identical quantity, each cylinder branch
Pipe connects each cylinder of engine respectively, and the cylinder branch pipe for connecting the adjacent cylinder of work done order connects the He of distribution header 1 respectively
Distribution header 24；House steward 2 connects distribution header 1 and distribution header 24 respectively by two dispensing branch 3.
In the present embodiment：The middle section position of dispensing branch 3 is flexible pipe 11, and each cylinder of engine is by an original house steward
2 connection controls, are changed to two distribution pipes while connect control, so if each pipe somewhat error, is assembled then more tired during installation
Difficulty, therefore install flexible pipe 11 additional, the assembling of convenient whole distribution piping and engine is installed；Two dispensing branch 3 are connected to
Distribution header 1 and the middle section position of distribution header 24, between house steward 2 and dispensing branch 3, dispensing branch 3 and distribution header one
Connected between 1 and distribution header 24 by flange, cylinder branch pipe is fixed by welding and distribution header 1 and distribution header 24
Connection.
As illustrated, enter each cylinder by distribution header 1 and distribution header 24 respectively after the air inlet of house steward 2, when starting
When the acting order of machine is 1-3-5-6-4-2,1 cylinder branch pipe 10,4 cylinder branch pipes 7 and the 5 cylinder branch pipes 6 connection cylinder branch of distribution header one 1,2
Pipe 9,3 cylinder branch pipes 8 and the connection distribution header 24 of 6 cylinder branch pipes 5, two cylinders of adjacent air inlet acting are separated, and add two cylinders
Between air inlet off time, alleviate air inlet interference, be advantageous to be lifted the air inflow of each cylinder natural gas, final realize is started
Each cylinder intake of machine is uniform, extends the service life of engine.
