Description
The utility model relates to a kind of igniter of spray gun, exactly, relates to a kind of pulse detonation igniter of supersonic speed internal combustion type spray gun.
Closely during the last ten years, along with developing rapidly of plasma spray technology, supersonic spray coating is with its coating interface bond strength height, and coating quality is good and quite be subjected to people's favor, especially enter the nineties after, become many focuses that reach country's research.The supersonic speed internal combustion type spray gun that the applicant succeeds in developing is the novel spray gun that mainly adopts liquid fuels such as kerosene, alcohol, this spray gun structure is fairly simple, and its ratio of performance to price in using operating process is better than the supersonic speed plasma torch and the supersonic spray gun of external development, has good economic benefits and popularizing application prospect.But, sparking mode such as the present common oxygen-acetylene torch that adopts of spray gun of this spray gun incompatibility, supercharging lighter, built-in resistance wire, its reason is: 1. liquid fuel such as kerosene, alcohol, because the burning-point height, igniting is difficulty quite; 2. Dian Huo flame is difficult for entering the spray gun combustion chamber; 3. situations such as the pressure of combustion gas, flow velocity are very complicated in the combustion chamber in the spray gun.
The purpose of this utility model provides a kind of pulse detonation igniter of supersonic speed internal combustion type spray gun, with the igniting that solves this spray gun problem of igniting.
The utility model is achieved in that it is made up of oxygen feeding pipe, fuel supply pipe and burning torch three parts, and it is characterized in that: above-mentioned fuel supply pipe is made of the air compressor that is linked in sequence, fuel tank, flow valve, electromagnetic switch valve and check valve; Above-mentioned oxygen feeding pipe then is made of the oxygen cylinder that is linked in sequence, stop valve, electromagnetic switch valve and flash-back arrestor; The end of above-mentioned two pipelines (being its outlet) symmetry respectively is installed in the corresponding dual-side of combustion chamber, square-section, burning torch middle part, and the rear portion of this burning torch is fixed with spark plug, and front end is a mini diameter tube shape jet pipe.
The central space of above-mentioned burning torch is the combustion chamber, and screwing in its rear portion screwed hole has spark plug, and the jet pipe external diameter of its front end and length should match with the fire hole size of spray gun.
Above-mentioned burning torch is made with stainless steel.
Characteristics of the present utility model are to be respectively equipped with an electromagnetic switch valve on oxygen feeding pipe and fuel supply pipe, and these two electromagnetic switch valves are to be opened by manual crawl simultaneously, at this oxygen and fuel oil simultaneously in the combustion chamber of spirt burning torch and be mixed into combustible gas rapidly moment, and immediately by the blast of the Pulse Electric spark initiation of the spark plug of synchronization action, the high pressure-temperature flame stream that blast is produced can ultrasonic high speed be implemented ignition operation from the ejection of burning torch jet pipe.This sparking mode overcome all inconvenience of sparking mode in the past preferably, ignition effectiveness height, good reliability, the igniting that has solved the supersonic speed internal combustion type spray gun of liquid fuels such as using kerosene, the alcohol difficult problem of igniting.
Fig. 1 is that structure of the present utility model is formed schematic diagram;
Referring to Fig. 1, the utility model is a kind of pulse detonation igniter of supersonic speed internal combustion type spray gun, and it mainly includes fuel supply pipe, oxygen feeding pipe and burning torch three parts, introduces its design feature below in conjunction with its course of work:
The compressed air that air compressor 1 on the fuel supply pipe produces extrudes back (if gaseous fuel with the liquid fuel of 2 li of fuel tanks, then directly from the pressure fuel bottle, extract), through the combustion chamber 11 of flow control valve 3, electromagnetic switch valve 4 and check valve 5 inlet point firelocks.Wherein flow control valve 3 is used for manually controlling the output flow of fuel, so that the proportioning of fuel metering and oxygen; 4 of electromagnetic switch valves are used to control the pulse supply of fuel, it controls its spool action by point driving switch, people's magnetic switch valve 4 is a normally closed type, when hand was pushed point driving switch, this electromagnetic switch valve powered up, and its spool is opened rapidly under the suction of electromagnet, open fuel channel, and after the pulse crawl time finished, its spool was return original position, valve-off rapidly under spring action.The structure of check valve 5 is by a spring steel ball to be pressed on the cone valve, and it mainly acts on is to prevent tempering.
After oxygen cylinder 9 on the oxygen feeding pipe was opened, oxygen wherein was through the combustion chamber 11 of commutation stop valve 6, electromagnetic switch valve 7 and flash-back arrestor 10 inlet point firelocks.The regular tap valve that above-mentioned commutation stop valve 6 has been on-off actions, 7 structures with above-mentioned electromagnetic switch valve 4 of electromagnetic switch valve are identical, be used to control the pulse supply of oxygen, and make the pulse firing synchronization action of these two electromagnetic switch valves 4,7 and spark plug 8 by same pulse firing circuit, when guaranteeing that fuel oil enters combustion chamber 11, can fully mix formation combustible gas, moment therewith with oxygen, implement simultaneously ignition operation again, produce pulse detonation.For preventing the explosion time of lighting a fire, the fuel flame flows to into oxygen channel, so be provided with flash-back arrestor 10 at the end of oxygen channel, its structure is identical with oxygen flash-back arrestor in the gas welding torch.
Be installed with spark plug 8 in the screwed hole at burning torch of the present utility model rear portion, its middle part is combustion chamber, square-section 11, and front end is the jet pipe 12 of 2.5 millimeters of Φ, and its external diameter and length should match with the fire hole size of spray gun.This burning torch uses stainless steel to make.
When manual crawl electromagnetic switch valve moment opens, fuel on two passages and oxygen will be in the moment combustion chambers 11 of spirt burning torch simultaneously, and be mixed into combustible gas rapidly, the electric pulse spark that is produced by the spark plug of synchronous effect is again ignited immediately, the high pressure-temperature flame stream that blast produces sprays from nozzle with supersonic speed, can implement ignition operation to spray gun.
The utility model is used at a high speed or the ignition operation of supersonic speed internal combustion type spray gun, comprises sand-blasting gun, shot-peening rifle, paint spray gun, cutting gun etc.
The utility model has been tested enforcement, and wherein the operating voltage of electromagnetic switch valve is 12V, opening and closing time ratio＜0.1 second, operating pressure P＜1.2MPa, and the opening pressure of check valve: P＞0.5MPa.
