Abstract
The invention belongs to combustion engine field of ignition systems, specifically design a kind of extension type ignition electric nozzle.Including the composition such as sparking plug component, forward flange disk, rear stub, cylinder, spring, limiting gasket, this spy's envelope, sealing ring and sealing shroud.Extension type sparking plug of the present invention can provide strikes sparks under combustion engine light condition, and by air pump pressure supply under high pressure, worst hot case, sparking plug component protrudes into combustion chamber and lights a fire again.It can fundamentally solve the problems, such as that sparking plug components over time is in high pressure, high-temperature work environment, to improve the reliability of ignition electric nozzle.
Description
Technical field
The invention belongs to combustion engine field of ignition systems, and in particular to a kind of extension type ignition electric nozzle.
Background technique
Ignition system product is the important component of gas turbine, and wherein ignition electric nozzle is used for the high pressure for generating igniter
Pulse electricity is changed into electric spark, to light the indoor fuel of burning.Ignition electric nozzle is typically mounted on combustion box, is under fire
Mouth front end is in combustion chamber, therefore ignition mouth is chronically at the working condition of high temperature, high pressure, seriously affected properties of product and
Service life is embodied in the end face ablation of ignition mouth, semiconductor piece breakage, firing voltage raising and air-tightness failure etc..
Summary of the invention
The present invention proposes a kind of extension type point to adapt to combustion engine ignition system high-energy, the property requirements of long-life
Thermoelectricity mouth can fundamentally solve the problems, such as that sparking plug components over time is in high pressure, high-temperature work environment, to improve igniting
The reliability of sparking plug.
The present invention adopts the following technical scheme that in order to solve the technical problem
A kind of extension type ignition electric nozzle includes sparking plug component, forward flange disk, rear stub, cylinder, spring, limit pad
Circle, this special envelope, sealing ring a, sealing ring b, sealing ring c, plain washer, spring washer, nut, stud and sealing shroud；The sparking plug
After component is threadedly coupled with sealing shroud, it is fixed in the cylinder by forward flange disk and rear stub；Before the spring is located at
In ring flange and the mounting groove of rear stub, forward flange disk and rear stub pass through the stud, plain washer, spring washer, spiral shell
Mother's fastening；The limiting gasket, this spy's envelope, sealing ring a are placed in sealing shroud in seal groove；The sealing ring b is placed in sealing shroud
In external seal slot；The sealing ring c is placed in the interior seal groove of rear stub.
In a free state, sparking plug component is bonded with rear stub, and sparking plug end point is outside combustion chamber；Rear stub
High pressure gas is passed through in venthole, can driving sparking plug component, ring flange direction is mobile forward, and sparking plug end is made to protrude into combustion chamber.
Being slidingly sealed between sealing shroud and forward flange disk is realized by limiting gasket, this spy's envelope, sealing ring a；Pass through sealing
Ring b realizes being slidingly sealed between sealing shroud and cylinder；Being slidingly sealed between sealing shroud and rear stub is realized by sealing ring c.
The sealing ring a, sealing ring b and sealing ring c use graphite material.
The invention has the advantages that:
For the present invention by design telescoping mechanism, the sparking plug components over time for avoiding ignition electric nozzle is in high pressure, high temperature work
The problem of making environment, to improve the reliability of ignition electric nozzle；The being slidingly sealed property for guaranteeing telescoping mechanism is sealed by graphite annulus；
Graphite annulus has high-temperature stability, and the present invention has high-temperature stability, can work normally under 450 DEG C of high temperature.
Detailed description of the invention
Fig. 1 is active extension type ignition electric nozzle half sectional view of the present invention.
Serial number in figure: 1 sparking plug component, 2 forward flange disks, 3 rear stubs, 4 cylinders, 5 springs, 6 limiting gaskets, 7 this spy envelope,
8 sealing ring a, 9 sealing ring b, 10 sealing ring c, 11 plain washers, 12 spring washers, 13 nuts, 14 studs and 15 sealing shrouds.
Specific embodiment
The technical solution of the invention is described in detail with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of extension type ignition electric nozzle, including sparking plug component 1, forward flange disk 2, rear stub 3, cylinder
4, spring 5, limiting gasket 6, this spy's envelope 7, sealing ring a8, sealing ring b9, sealing ring c10, plain washer 11, spring washer 12, spiral shell
Mother 13, stud 14 and sealing shroud 15.
After sparking plug component 1 is threadedly coupled with sealing shroud 15, the cylinder 4 is fixed on by forward flange disk 2 and rear stub 3
In；Spring 5 is located in forward flange disk 2 and the mounting groove of rear stub 3, and forward flange disk 2 and rear stub 3 pass through stud 14, put down
Washer 11, spring washer 12, nut 13 fasten；Limiting gasket 6, this spy's envelope 7, sealing ring a8 are placed in seal groove in sealing shroud 15
In；Sealing ring b9 is placed in 15 external seal slot of sealing shroud；Sealing ring c10 is placed in the interior seal groove of rear stub 3.
Being slidingly sealed between sealing shroud 15 and forward flange disk 2 is realized by limiting gasket 6, this spy's envelope 7, sealing ring a8；It is logical
It crosses sealing ring b9 and realizes being slidingly sealed between sealing shroud 15 and cylinder 4；Sealing shroud 15 and rear stub are realized by sealing ring c10
Being slidingly sealed between 3.Sealing ring a8, sealing ring b9 and sealing ring c10 use graphite material, and graphite annulus has self-lubricating and Nai Gao
Temperature characteristics, it is ensured that the present invention has characteristic resistant to high temperature.
Working principle is as follows:
In free state, under the action of spring 5, sparking plug component 1 is bonded with rear stub 3, and sparking plug end point is being fired
It burns outdoor；When combustion engine is lighted a fire, be passed through high pressure gas into the venthole of rear stub 3, driving sparking plug component 1 to
2 direction of forward flange disk is mobile, and sparking plug end is made to protrude into combustion chamber to light combustion gas；After combustion engine starts, the venthole of rear stub 3
Middle gas decompression is to standard atmospheric pressure, and under the active force of spring 5, sparking plug component 1 rebounds, i.e. sparking plug end falls back on combustion chamber
Outside.
