Plunger-type dispensing valve for the rapid deposition of adhesive to road pavement surfaces for enabling the fixation of pavement markers to road pavement surfaces

a technology of adhesive and dispensing valve, which is applied in the direction of valve operating means/releasing devices, functional valve types, valves, etc., can solve the problem that the valve needs to dispense adhesive materials extremely quickly, and achieve the effect of facilitating soft starts, minimizing the likelihood of formation, and minimizing the pressure prevailing at the valve member or shutoff blad

Benefits of technology

The patent describes a dispensing valve that has a unique structure that allows for controlled and safe operation. When the valve is in its fully closed position, a valve plunger is positioned to prevent adhesive material from flowing downward and to recirculate the material through the system. When the valve is in its fully open position, the valve plunger is positioned to allow the adhesive material to flow freely. This structure ensures that the valve can control the flow of adhesive material and minimize the likelihood of residual material or splatter being discharged from the output of the valve.

Problems solved by technology

In addition, the valve needs to dispense the adhesive material extremely quickly.

Embodiment Construction

[0017]Referring now to the drawings, and more particularly to FIG. 1 thereof, the new and improved plunger-type dispensing valve is disclosed and is generally designated by the reference character 100. More particularly, it is seen that the dispensing valve 100 comprises a valve housing 102 wherein the valve housing 102 effectively comprises a first uppermost section 104, a second intermediate section 106, and a third lowermost section 108. A piston-cylinder assembly is disposed within the first uppermost section 104 of the valve housing 102 and is seen to comprise a piston which, in turn, comprises a piston head 110 and a piston rod 112, the piston head 110 being vertically movable within a cylinder portion 114 of the first uppermost section 104 of the valve housing 102. A lower end portion of the piston rod 112 is fixedly connected to a first uppermost enlarged diameter portion 116 of a valve plunger 118. The piston-cylinder assembly may be operated either pneumatically or hydraul...

Abstract

A reciprocating plunger-type valve mechanism or assembly, which can be utilized in conjunction with adhesive dispensing applicators to control the dispensing of adhesive compositions which are to be used in connection with the bonding, securing, or fixation of pavement markers to road pavement surfaces, is disclosed. The mechanism or assembly comprises dual shutoff locations in connection with the supply of the incoming adhesive material so as to effectively reduce the prevailing pressure upon the shutoff blade controlling the adhesive material dispensing / discharge port whereby soft pressure starts and controlled deposition quantities are enabled while the generation of residual adhesive material or splatter is avoided.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to dispensing valve mechanisms or assemblies, and more particularly to a new and improved reciprocating plunger-type dispensing valve mechanism which can be utilized in conjunction with adhesive dispensing applicators to control the dispensing of adhesive compositions which are to be used in connection with the bonding, securing, or fixation of pavement markers to road pavement surfaces.BACKGROUND OF THE INVENTION[0002]Pavement markers are conventionally applied to road pavement surfaces by means of a suitable adhesive. Various adhesive dispensing mechanisms are conventionally mounted upon a road vehicle that moves along a road pavement surface upon which the pavement markers are to be applied. The adhesive material is dispensed onto a predetermined location of the road pavement surface by means of the particular adhesive dispensing mechanism or apparatus, and subsequently, a technician / operator, riding upon the roa...
