Valve manifold box and method of making same
First Claim
1. A valve manifold box to enclose manifolds controlling the flow of potentially hazardous liquids which need containment in the event of valve leaks, the box comprising:
- a non-metallic box having five sides integral with each other, four of said sides defining an opening;
a cover panel sealingly held against adjacent edges of four of the sides to form a liquid retaining enclosure to contain any leakage from valves of a manifold within the box; and
a plurality of fittings spin welded in sealing relationship to at least part of the walls;
said fittings adapted to be in communication with the interior of the box manifold and with liquid carrying tubes connected thereto.

Abstract
A manifold box adapted to contain manifolds for valves controlling the flow of potentially hazardous liquids. This is a rotationally cast sealed plastic box enclosing the valves to contain any leaks from the valves and allow any leaking liquid to drain from the box through a drain tube at the bottom of the box to prevent the liquid from leaking onto surfaces below or adjacent to the valves. Attachment engaging "tee-nuts" are cast in place within the walls of the box and fittings for tubing connections are spin welded to the walls of the box. The box has a front access opening sealingly closed by a hinged plastic cover panel. In one embodiment the box is rectangular and is designed with two adjacent sloping walls which permit drainage of liquid from the box into a drain tube regardless of whether the box is mounted vertically or horizontally. In another embodiment the box is square and has one sloping wall containing a drain connected to a drain pipe.

7. A valve manifold box to enclose manifolds controlling the flow of potentially hazardous liquids which need containment in the event of valve leaks, the box comprising:
-
A non-metallic molded box having a back wall, two side walls, a top wall and a bottom wall; the top, bottom and side walls defining a front opening lying opposite to the back wall; a front cover panel sealingly covering the opening to prevent leakage of liquid from the box, the front cover panel being capable of being opened to provide access to the interior of the box; at least one wall of the box containing a drain port and said wall being sloped toward the drain port; a plurality of spin welded fittings sealingly attached to at least part of the walls to provide connections for liquid carrying tube members; and means attaching a manifold assembly inside the box, whereby said manifold assembly is adapted to be in communication with the liquid carrying tubes extending through the spin welded fittings.
