Description
Technical field
The present invention relates to gas engine technical field, more particularly to a kind of valve for being easy to leakage check and there is the valve
The gas engine gas burning system of door.
Background technology
The fuel gas pipeline of gas machine is as leaked and making combustion gas air inlet, it would be possible to cause the equivalent risk that explodes, because
The fuel gas pipeline design anti-leak of this gas machine peculiar to vessel has high demands.According to the requirement of gas engine safety peculiar to vessel, gas machine
Fuel gas pipeline should be double-layer cavity structure, and inner chamber is blast tube, and exocoel is scavenging chamber.Scavenging chamber is connected with air exhauster, as in
Chamber blast tube is leaked, then the combustion gas for leaking to scavenging chamber will drain into safe place by air exhauster, and prevent leakage combustion gas exists
In cabin, accumulation brings danger.
The gas burning system being made up of main combustible pipe road and pre- fuel gas pipeline is the species of existing gas engine gas burning system
One of.The pre- fuel gas pipeline connection precombustion chamber of this gas burning system, precombustion chamber are connected with main combustion chamber by spray orifice, and spark plug is first
The gaseous mixture in pre-burning room is lighted, pre-burning indoor temperature, pressure rise is made, high-temperature gas sprays into main combustion chamber by spray orifice, and lights
Gaseous mixture in main combustion chamber.Due to this pre- fuel gas pipeline after precombustion chamber, combustor, exhaust duct with environmental communication, therefore
Pipeline is not closed, and cannot carry out performing leak test to fuel gas pipeline, it is impossible to guarantee pipe component and connection before gas machine work
Place causes gas machine peculiar to vessel to there is certain potential safety hazard in the problem for prevent gas leakage without leakage.
Content of the invention
In order to solve above-mentioned technical problem, it is an object of the invention to provide a kind of valve for being easy to leakage check and having
The gas engine gas burning system of the valve, closes can pipeline by the valve, and then can be before gas machine work to combustion
Air pipe carries out performing leak test.
According to an aspect of the invention, there is provided a kind of valve for being easy to leakage check, including：
Shell, with inlet portion and export department；
Through hole, makes the inlet portion connect with export department by through hole；
Valve closure member, by valve closure member scalable through hole；
At least two scavenging cell bodies, respectively on the end face for being arranged in inlet portion and export department in a ring, in order to scavenging
Chamber connects；
First sealing ring, is arranged in the inner side of scavenging cell body, in order to realize that the through hole and the sealing of blast tube connect
Connect, and then realize the isolation of through hole and scavenging chamber；
Second sealing ring, is arranged in the outside of scavenging cell body, in order to realize being tightly connected for scavenging cell body and scavenging chamber, enters
And realize the isolation of scavenging cell body and indoor environment；
Scavenging passage, is arranged on the body interior of shell and connects two scavenging cell bodies.
Existing ball valve product on market, sealing property meet require, but do not possess double-layer cavity structure, it is impossible to pre-
On fuel gas pipeline, the function of gas pipeline leakage scavenging is further realized in the scavenging chamber connection of other parts, is unsatisfactory for gas machine peculiar to vessel
Security requirement.It is easy to the valve of leakage check, the structure design with dual chamber be installed to pre- fuel gas pipeline
On.Close can pipeline by the valve, and then performing leak test can be carried out to fuel gas pipeline before gas machine work；Another
The aspect valve can ensure once the joint face seal failure that flows through of combustion gas, and the combustion gas of leakage can enter scavenging chamber and in time by band
To safe place.
Further, the cross sectional shape of scavenging cell body is triangle or rectangle.
Further, valve body leakage scavenging passage is additionally provided with shell, and valve body leaks scavenging passage and lets out multiple in valve
Dew risk point insertion, and with scavenging channel connection, when there is leak point on valve body, it can be ensured that the combustion gas of leakage quilt in time
Take away.
Preferably, the valve is ball valve, and compact conformation, sealed reliable with wear-resisting, good seal performance, switch light, use
The advantages of life-span length.
Further, ball valve is separation type ball valve, and its shell includes left shell and right shell body, and valve body leakage scavenging passage exists
It is circular layout at the joint face of left and right housing, the joint face of ball valve or so housing is disclosure risk point, arranges valve body in this place and lets out
Drain sweep gas passage, can prevent from revealing, at valve, the danger that combustion gas air inlet brings.
Further, valve closure member includes the handle of valve element and control valve element.Using conventional valves form, structure letter
Single, processing technology is ripe.
Further, the case surface around the handle, is provided with the mark for representing valve switch, can prevent behaviour by mistake
Make.
Further, case surface is provided with the stop screw for limiting bat-handle switch position.
According to another aspect of the present invention, there is provided a kind of gas engine gas burning system with the valve, in pre-burning
On air pipe, the above-mentioned valve for being easy to leakage check is set up.
For being easy to the valve of leakage check, the valve to be located on pre- fuel gas pipeline in gas engine gas burning system, should
When valve is opened, pre- fuel gas pipeline is unimpeded, and gas machine can normal work；During the valve closing, pipeline is closed, and can carry out sealing
Test.
Compared with prior art, the invention has the advantages that：
Designed by unique valve mechanism, solve traditional pre- fuel gas pipeline and do not close and then cannot be in gas machine
The technical problem of performing leak test is carried out before work to fuel gas pipeline.By the valve is added on pre- fuel gas pipeline, a side
Face can close pipeline before gas machine work, so as to realize the performing leak test to fuel gas pipeline；On the other hand in gas
When machine works, the valve can ensure once the joint face seal failure that flows through of combustion gas, the combustion gas of leakage can enter scavenging chamber and and
When be taken to safe place, increased safety of the gas machine peculiar to vessel in terms of gas leakage is prevented.
On the basis of ordinary ball valve structure, by the double O-ring sealings of end face, triangle or rectangular ventilation groove and brill
The simple machined structures such as hole insertion, you can make ball valve meet the security requirement of gas machine fuel gas pipeline.The valve arrangement is tight
Gather, processing is simple, and manufacturability is good.
