Valve manifold

摘要

A valve manifold has a housing including a central mixing chamber and a shell surface. The shell surface has at least two valve ports that are each associated with one valve. A first valve port has three openings and the additional valve ports each have at least two, preferably three openings. A respective first opening of the valve ports is in direct fluid communication with the central mixing chamber, and the second and third openings of the valve ports are each in fluid communication with an inflow or outflow via a duct. An external port is provided which is in direct fluid communication with the mixing chamber via a duct.

1. A valve manifold comprising:
a body having at least first, second, and third side faces; a mixing chamber formed within the body; at least first and second valve ports arranged on an external surface of the body such that the first valve port is formed on the external surface of the first side face and the second valve port is formed on the external surface of the second side face, and wherein each valve port of the at least first and second valve ports is adapted to receive a diaphragm valve; wherein each valve port of the at least first and second valve ports includes a first opening, a second opening, and a third opening wherein each first opening is in direct fluid communication with the mixing chamber, each second opening is in fluid communication with a dedicated second opening flow duct, and each third opening is in fluid communication with a dedicated third opening flow duct; and wherein each first opening and second opening are separated by a first web accessible at each of a respective one of the at least first and second valve ports for a respective diaphragm valve, and wherein each first opening and third opening are separated by a second web accessible at the respective on of the at least first and second valve ports for the respective diaphragm valve; one additional fluid connection which extends in the body from an external port on the external surface of the body directly into the mixing chamber, wherein the external port is separate from the first and second valve ports; and wherein the first, second, and third side faces form a periphery of the body, and wherein the first, second, and third side faces extend in a vertical direction between upper and lower end faces of the body, and wherein the external port is formed within the upper end face and comprises a direct inflow to the mixing chamber without flowing through the dedicated second and third opening flow ducts of the first and second valve ports.
