Abstract
The invention discloses a high-pressure-resisting combustion chamber with a laser lens and an observation window convenient to wipe. The high-pressure-resisting combustion chamber comprises a high-pressure-resisting combustion chamber body, a sealing ring, a cleaning plug and leveling screws. The outer wall of the high-pressure-resisting combustion chamber body is provided with a cleaning window, and the cleaning window is the same as the observation window of the high-pressure-resisting combustion chamber body in height. The cleaning plug is arranged on the cleaning window, and the sealing ring is arranged between the cleaning plug and the cleaning window. The multiple leveling screws are symmetrically distributed at the bottom of the high-pressure-resisting combustion chamber body. The high-pressure-resisting combustion chamber is simple in structure and low in price; when the laser lens and the observation window are wiped after a laser ignition experiment is completed, the laser lens and the observation window can be wiped just by screwing off the cleaning plug, and therefore the experiment efficiency is greatly improved because neither an airtight test is needed nor beam-focusing needs to be conducted again after wiping is completed.
Description
Technical field
The invention belongs to cleaning equipment field, firing chamber, be specifically related to a kind of high pressure resistant firing chamber being convenient to wiping laser lens and view window.
Background technology
In research solid propellant ignition burning performance, laser is as radiation source, and the energy because of it with output is high, and exposure time and output energy adjustable, the advantages such as anti-electromagnetic interference capability is strong, have become the Novel ignition mode of research solid propellant both at home and abroad.The experiment of the combustion characteristics of research propellant is carried out mostly in a combustion chamber, a large amount of smoke contamination laser lens and view window can be discharged during propellant combustion, the metallic aluminium ion of the thawing that propellant combustion produces can stick on laser lens and view window, therefore needs frequent wiping laser lens and view window.
Chinese patent CN201410519983.X discloses a kind of high pressure resistant temp. controllable laser ignition experimental provision, the firing chamber be made up of lens and view window, on the one hand because bottom of combustion chamber does not have the leg of balancing, there is foozle in the screw connecting firing chamber bottom end cover and cavity, tighten the basal plane out-of-flatness of screw after-burner, at the trial, firing chamber is easily rocked, and affects experimental result; On the other hand the multiple screws being used for fixing firing chamber upper end cover must all screw down when wiping view window and laser lens by this firing chamber, very consuming time, and having after wiping view window and lens needs multiple gib screw to tighten.Air tightness test will be re-started afterwards, and again to light, the real igniting experiments time only needs one minute, but probably need half an hour in order to wiping laser lens and view window, again also need one hour to light, therefore this firing chamber can reduce conventional efficient greatly.
Ox and woods are in " novel solid Ignition of Energetic Materials and combustion characteristics research " literary composition, and propose to roll up weldering by the stainless-steel sheet that 3.5mm is thick and form firing chamber, it is the window of 120mm that a diameter is respectively opened on both sides, firing chamber.This firing chamber is similar with the firing chamber that Wang Hongmei designs, in order to wiping laser lens and view window with again also need a large amount of time to light.
Summary of the invention
The object of the present invention is to provide a kind of high pressure resistant firing chamber being convenient to wiping laser lens and view window, one is that the screw solved owing to connecting firing chamber bottom end cover and cavity exists foozle, tighten the irregular problem of basal plane of screw after-burner, two is solve wiping laser lens and view window will be dismantled many screws and cause the problem of length consuming time.
The technical solution realizing the object of the invention is: a kind of high pressure resistant firing chamber being convenient to wiping laser lens and view window, comprise high pressure resistant firing chamber, O-ring seal, clean plug and levelling bolt, high pressure resistant outer wall of combustion chamber has clean window, the view window of described clean window and high pressure resistant firing chamber is contour, clean plug is arranged on clean window, be provided with O-ring seal between clean plug and clean window, several levelling bolts are symmetrically distributed in high pressure resistant bottom of combustion chamber.
Described clean plug comprises blocking, positioning disk and stubborn cap, positioning disk is between blocking and stubborn cap, and positioning disk diameter is greater than blocking diameter, and blocking is arranged in clean window, positioning disk is positioned at high pressure resistant outer wall of combustion chamber, and O-ring seal is positioned at the joint face of blocking and positioning disk.
Described stubborn cap is positioned at positioning disk center.
Described blocking is right cylinder, and outer wall is provided with external thread
Compared with prior art, its remarkable advantage is in the present invention: (1) saves experimental period, improves conventional efficient: when wiping laser lens and view window, and only clean plug is backed out by needs, just can wiping laser lens and view window; Do not need after wiping completes to carry out leakproofness test, also not again to light, greatly improve conventional efficient.
(2) structure is simple, cheap.
Accompanying drawing explanation
Fig. 1 is the one-piece construction schematic diagram being convenient to the high pressure resistant firing chamber of wiping laser lens and view window of the present invention.
Fig. 2 is the A place partial enlarged drawing being convenient to the high pressure resistant firing chamber of wiping laser lens and view window of the present invention.
Fig. 3 is the clean plug structure schematic diagram being convenient to the high pressure resistant firing chamber of wiping laser lens and view window of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Composition graphs 1, Fig. 2 and Fig. 3, a kind of high pressure resistant firing chamber being convenient to wiping laser lens and view window, comprise high pressure resistant firing chamber 1(commercial, the patent No. is CN201410519983.X), O-ring seal 2, clean plug 3 and levelling bolt 4, high pressure resistant firing chamber 1 outer wall has clean window, the view window of described clean window and high pressure resistant firing chamber 1 is contour, clean plug 3 is arranged on clean window, open view window and laser lens that clean plug 3 can clean high pressure resistant firing chamber 1, clean and be provided with O-ring seal 2 between plug 3 and clean window, when not carrying out clean, the sealing of high pressure resistant firing chamber 1 can be ensured.Several levelling bolts 4 are symmetrically distributed in bottom high pressure resistant firing chamber 1, and levelling bolt 4 is for carrying out leveling to high pressure resistant firing chamber 1.Levelling bolt 4 adopts 4 usually, is symmetrically distributed in bottom high pressure resistant firing chamber 1.
Described clean plug 3 comprises blocking 3-1, positioning disk 3-2 and stubborn cap 3-3, positioning disk 3-2 are blocking between 3-1 and stubborn cap 3-3, and positioning disk 3-2 diameter is greater than blocking 3-1 diameter, and blocking 3-1 is arranged in clean window, for blocking clean window.Positioning disk 3-2 is positioned at high pressure resistant firing chamber 1 outer wall, and O-ring seal 2 is positioned at the joint face of blocking 3-1 and positioning disk 3-2, and positioning disk 3-2 coordinates with O-ring seal 2, ensure that the location of clean plug 3 and the sealing of high pressure resistant firing chamber 1.
