发明名称 PROPORTIONIERUNGSVENTIL ZUM VOLUMETRISCHEN AUFTEILEN EINER STROEMUNG IN BESTIMMTEN VERHAELTNISSEN
摘要 <p>A proportioning valve is provided for volumetric proportioning of flow in an influent fluid line of the valve between two effluent fluid lines of the valve, particularly adapted for use in sensing main flow and adjusting purge flow in proportion to main flow in a twin-tank heatless or heat-reactivated adsorbent bed gas-fractionating apparatus, such as a desiccant bed dryer. The valve features two valve elements, each movable independently of the other, one sensing and responding to flow through one variable opening, and the other responding to and cooperating with the first in adjusting flow through a second variable opening, the first variable opening being in the influent fluid line of the valve, and the second variable opening being in one effluent fluid line of the valve, the first and second valve elements in combination controlling flow in the one effluent valve line at a desired volume and pressure in relation to pressure and flow in the influent valve line.</p>
