Description
The application is be on October 22nd, 2003, denomination of invention the applying date for " plural component spray gun that is used for rapidly solidified material " and application number be dividing an application of 200380101833.7 Chinese invention patent application.
The US application serial No. 60/420,085 that the application requires to submit on October 22nd, 2002, on January 21st, 2003 submit to 60/441,575,60/462,124 the rights and interests submitted on April 10th, 2003.
Technical field
The present invention relates to be used for the plural component spray gun of rapidly solidified material.
Background technology
Known spray foam and the similar material of being used for of plural component spray gun that uses with rapidly solidified material.Although this spray equipment is effective substantially at these materials of spraying, they often bother very much, and need a plurality of instruments and sizable labour intensity to dismantle and clean.
Summary of the invention
Plural component spray gun is designed for the rapidly solidified material of spraying as foam and so on.In order to realize this purpose, the air cleaner pattern design of this rifle makes and can use at an easy rate with minimum instrument.For example, under the situation of tool using not,, with coin or screwdriver they are taken out from the fluid shell then, can mount and dismount the side seal cover by retainer ring is pulled down.The sealing cover is easy to dismounting and cleaning.
Similarly, by locking ring (using hand) is turned on, the fluid shell can be pulled down from handle.Under situation about not dismantling, lubricating oil directly can be sprayed into and be used in the rifle storing, and be sprayed onto in the whole hybrid chamber by clean air.This hybrid chamber is rotationally connected with 1/8 circle with piston and is easy to separate.Air duct in the rifle body that can see is easy to machining, and if stop up and to allow more easily to keep in repair.
Fluid be not exposed under the airborne situation, just can realizing cleaning impingement holes.The corresponding surface of the sealing surfaces of this side seal covering device and hybrid chamber is made by the hard metal material as 440C stainless steel and so on, has the flexible outstanding durability of metal and metal sealing.
In the mechanical purge version of this rifle, pore is provided with a pair of isolated cornu, thereby corresponding with the size on plane on the cleaning chamber fixator, to allow dismounting and fixing holder under the situation of not using independent instrument.
Typical existing machinery cleaning rifle has two groups of fluid seals, with sealed valve stem.The primary seal that is generally interference engagement is Delrin A-F, and is uncontrollable.Forward end seal also is an interference engagement, is made by UHMWPE, and also is uncontrollable.When this main seal wears, rifle will " splash " goes out the front end of rifle, stopped nozzles.Seal is usually with similar speed wearing and tearing, so when the rifle splash, the user all replaces these two seals.
Impact cavity forms first and second annular chambers of opening around its circle spacing, with first and second groups of passages that described chamber is connected with its inner passage.These first and second groups of passages enter the inner passage at the same axial position place, thereby prevent to produce the lead and lag situation of unmixed material.
Be provided with the easy governor motion that is used for channel washer.Can realize this simple adjusting by rotating the channel washer that is positioned at the rifle rear portion with nut spanner or similar tool.This channel washer threaded engagement in piston, utilize simultaneously in the hole with piston on complementary flat, prevent that this piston from preventing to rotate with respect to the rifle body.
From the description below in conjunction with accompanying drawing, these and other purposes of the present invention will more fully show, and wherein identical Reference numeral is represented identical or similar parts in these several accompanying drawings.

The specific embodiment
Air cleaner spray gun of the present invention illustrates in accompanying drawing 1,2 and 7 fully.Spray gun comprises rifle body 1.As finding out from accompanying drawing 2, air duct 1a is manufactured in the sight line fully, to be easy to machining and maintenance.When pulling down piston 15, can see the whole length of each passage, and be easy to clean with drill bit.
Be provided with dismountable piston stop 28, and it can activate with safety lock 4 (through promoting and rotation).O shape ring 24 and spring 30 are between this piston stop and safety lock.Rear cylinder cap 5 is screwed on the rear portion of rifle body 1 by screw thread, and seals with O shape ring 14.Piston 15 slides on the inside of rifle body 1 (it to have complementary plane, to prevent relatively rotate), and this piston has an outstanding axle 15a.Be provided with sealing O shape ring 16 and 17.
Side seal covering device 18 and 20 comprises sealing shroud shell 18a and 20a, spring 18b and 20b, seal 18c and 20c and O shape ring 18d, 20d, 18e and 20e.Side seal covering device 18 is made by hard metal material with 20 the sealing surfaces and the corresponding surface of hybrid chamber 19, as the 440C stainless steel.
Detect valve 26 and be positioned on two sides of fluid shell 11, each detects valve 26 and all is made up of shell 26a, screw 26b, carbonization ball 26c, filter screen 26d, spring 26e and O shape ring 26f and 26g.Notice that fluid stream flows out through filter screen internally, thereby fluid pressure can not destroy filter screen 26d as taking place in existing rifle.
Lubricating oil zerk fitting 25 is arranged in the fluid shell, and is connected on the clean air passage.Fill up lubricating oil in the fluid passage in this permission hybrid chamber 19 and the front end of rifle, this lubricating oil mixes with clean air, to prevent aggegation (setup) and crystallization.The spray gun that this injection will allow to clean is fully deposited whole evening.Similarly, pore 10 plays the effect of previously deriving of the air after the cleaning around nozzle 19a, thereby prevents to accumulate in above it.
In the mechanical purge version of rifle 40, pore 110 is provided with a pair of isolated cornu 110A, thereby corresponding with the size of plane 142A on the impact cavity fixator 142, to allow dismounting and fixing holder 142 under the situation of not using independent instrument.
Be provided with the easy governor motion that is used for channel washer 148.This simple governor motion can be realized by the rear end 148A that rotates the channel washer that is positioned at the rifle back with nut runner or similar tool.Channel washer 148 threaded engagement utilize the complementary flat on hole and the piston (being respectively 101A and 115A) to prevent that this piston 115 from rotating with respect to rifle body 101 in piston 115 simultaneously.
The adjustable cushion of the present invention 154 that is fixed on the position with nozzle fixator 150 (it is fixed nozzle 152 also) allows the user to be close to preceding seal, to prevent splash.This regulating power allows the user more not using up one day at least under the situation of change owner liner.
When regulating air-flow or changing nozzle, the operating personnel of engine cleaning gun must often activate the safeties of rifle.These safeties 158 must be in all cases easy operatings all.The spray of crossing of foam or polyureas often covers rifle, makes that the actuating of safeties is very difficult.Even guarantee that by the bursting tube 156 that polyethylene is made these safeties 158 also can moved freely when covering by the mistake spray, and shown in accompanying drawing 15 and 16.Foam or polyureas can not adhere on the polyethylene.If on insurance actuator 160 accumulation is arranged, when activating safeties 158, polyethylene will make spray come off.
Under the situation that does not break away from the spirit and scope of the present invention that are defined by the following claims, can make variations and modifications to this spray gun.
