Applicator system

Abstract

An applicator for combining and applying components of a multi-part curable system includes a proportioning valve having a body with a plurality of separate internal passageways, each communicating with a separate inlet recess and a separate outlet opening maintaining each component in separate condition in the valve. Each inlet recess is adapted to be connected to a source of one component of a multi-part curable system and the discharge openings discharge the two components separately from a common nose into an attached static mixing applicator nozzle.

1 . A proportioning valve for supplying components of a multi-part curable system comprising a proportioning valve having a body including a plurality of separate internal passageways, each communicating with a separate inlet recess and a separate outlet opening thereby maintaining each component in separate condition therein, wherein each said inlet opening is adapted to be connected to a source of one component of a multi-part curable system and wherein said discharge openings are adapted to discharge said components separately from spaced openings in a common nose into a common chamber for mixing.

       5 . A proportioning valve as in  claim 1  wherein a number of components supplied is 2 and wherein said mixing valve includes oppositely disposed threaded inlet passages designed to accommodate inlet elbow fittings connected to component sources.  
   
   
       6 . A proportioning valve as in  claim 5  wherein said inlet recesses are of different diameters.  
   
   
       7 . The proportioning valve of  claim 1 , wherein the internal passageways are configured to obtain a predetermined mixing proportion of components of the multi-part curable system.  
   
   
       8 . The proportioning valve of  claim 1 , wherein the input flow of components to the valve body is modulated, wherein the output flow of components from the valve body is controlled.  
   
   
       9 . The proportioning valve of  claim 1 , wherein one of the inlet opening and outlet opening of at least one internal passageway is configured different from one of the inlet opening and outlet opening of another internal passageway.  
   
   
       10 . The proportioning valve of  claim 1 , wherein the common chamber for mixing is removably attached to the valve body and disposable.  
   
   
       11 . The applicator of  claim 3 , wherein the internal passageways are configured to obtain a predetermined mixing proportion of components of the multi-part curable system.  
   
   
       12 . The applicator of  claim 3 , wherein the input flow of components to the valve body is modulated, wherein the output flow of components from the valve body is controlled.  
   
   
       13 . A method for dispensing mixed materials as a continuous bead, comprising: 
 providing a valve body having a plurality of separate internal passageways, with each passageway extending from a separate inlet opening to a separate outlet opening;    coupling each inlet opening to a source of material to be mixed;    coupling a static mixing applicator nozzle to the valve body, wherein the separate outlets openings are in fluid communication with the applicator nozzle; and    mixing all the materials separately discharged from the valve body through the applicator nozzle forming a continuous bead of mixed materials.    
   
   
       14 . The method of  claim 13 , including the step of configuring the relative size of each passageway to obtain a predetermined mixing proportion of materials to be mixed in the applicator nozzle.  
   
   
       15 . The method of  claim 14 , wherein one of the inlet opening and outlet opening of at least one passageway is configured different from one of the inlet opening and outlet opening of another passageway.  
   
   
       16 . The method of  claim 13 , including the step of modulating the input flow of material to the valve body wherein the output flow from the valve body is controlled.  
   
   
       17 . The method of  claim 13 , wherein the applicator nozzle is removably attached to the valve body.  
   
   
       18 . The method of  claim 17 , wherein the applicator nozzle is disposable.  
   
   
       19 . The method of  claim 13 , wherein a number of materials to be mixed is two.  
   
   
       20 . The method of  claim 13 , wherein the valve body includes oppositely disposed threaded inlet passages in communication with the inlet openings and configured to receive inlet elbow fittings coupled to the material sources.  
   
   
       21 . A device for dispensing at least first and second materials which form a curable material when combined, the device comprising: 
 a housing having a first conduit separate from a second conduit, the first and second conduits having respective units being configured for connection to sources of the first and second materials respectively; and    a removable disposable mixing device, the conduits further including outlets, wherein the mixing device is removable coupled to housing so that material from the outlets is flowable into and mixed within the mixing device.    
   
   
       22 . The device of  claim 21 , wherein the mixing device is formed from plastic.  
   
   
       23 . For use with the housing of  claim 21 , a removable, disposable mixing applicator nozzle.
