Benefits of technology

The invention is a modular media control valve that allows for easy repair and replacement of components without replacing the entire valve. The valve includes a valve body, plunger, and metering system. A sleeve is positioned inside the valve body, with a particulate media inlet opening in the sleeve. The plunger is attached to a shaft, which in turn is attached to the control knob. The valve opening can be calibrated by visual indication of the alignment of the metering marks on the valve body with the bottom edge of the control knob. The valve is designed to facilitate assembly and improve the seal integrity of the assembled valve. The invention simplifies the design and manufacture of the valve, making it easier to repair and replace.

Problems solved by technology

Because of the harsh environment of the valve use, the wear between the plunger and the body of the valve can cause failure of various components which then have to be periodically replaced.
Likewise, the sleeve can only be replaced by disassembling the entire valve.
Further, because the bolts 3 pass through the cap, body, and sleeve and into the base, a full body gasket cannot be incorporated in the design.

Embodiment Construction

[0026]The present invention is directed to a valve for controlling the flow of a media to a fluid stream, referred to herein as a media control valve. By media, it is meant any material or materials that may be desired to be added to another material or materials. While various solid, fine particulate, blasting media, such as sand, metal shot, and the like, are used by way of example herein, the media that may be supplied by the media control valve of the present invention is not so limited, and may include a wide variety of materials including liquids and gasses as well as solid particles. The subject invention is particularly useful when used in applications containing solid particles of a defined maximum particulate size.

[0027]In one embodiment, the media control valve of the present invention includes a valve body having a media inlet and a media outlet. A housing is connected to the valve body. A plunger is positioned within the valve body. A sleeve is mounted in the body and r...

Abstract

A media control valve has a valve body having a media inlet and a media outlet and a plunger which is positioned within the valve body. The plunger is connected to a metering control assembly in the bore of the valve body and can be removed without disturbing the control assembly. A sleeve is positioned in the valve body between the valve body and the plunger. The sleeve includes an integral seal for sealing the valve to a flow device such as a base. The valve stem or post for housing the control knob may have metering marks for visually indicating the position of the plunger relative to the sleeve. The control knob on the valve is aligned with the metering marks on the valve body, whereby the valve opening may be calibrated by visual indication of the alignment of the metering marks with the lower edge of the control knob.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention is related to media control and, more specifically, media control valves used to control the flow of a media into a fluid stream as part of an apparatus for treatment of a surface.[0003]2. Description of the Related Art[0004]A typical media control valve is the pipe side valve shown and described in U.S. Pat. No. 4,322,058, issued to Thompson, et al on Mar. 30, 1982 (the “Thompson Patent”). This valve has been has been widely accepted in applications where the flow of particulate material, such as sand or other abrasive material, from a tank or hopper, is fed into a blast line for propelling the particulate material or media through a nozzle.[0005]As shown in the Thompson Patent, the valve has a unitary plunger which is movable axially with respect to a lateral particulate material inlet between positions closing and opening the inlet. The plunger is moved by rotation on a threaded portion of the p...
