Title:
HIGH TEMPERATURE FLUID CONTROL VALVE DEVICE
Document Type and Number:
Japanese Patent JPH0727232
Kind Code:
A
Abstract:

PURPOSE: To provide a high temperature fluid control valve device low-priced and excellent in durability by providing a cover piece at the inner wall upper part of an inflow port side body in a valve part accommodating part in such a way as to protrude downward being spaced by the required dimension from a valve body, thereby reducing the heat load of the valve part.

CONSTITUTION: A connecting part between the right end of an upper wall 1d in a valve chamber 1a and the inner wall upper part of an inflow port 1b is provided with a cover piece 22 protruding downward so as to cover the outer peripheral surface on the right side of a valve part 14a, that is, the outer peripheral surface on the inflow port 1b side where exhaust gas flows in. With this cover piece 22 thus provided, the flow direction of exhaust gas flowing in from the inflow port 1b is deflected so as to prevent the right side face of the valve part 14a from being directly exposed to high temperature exhaust gas, this part is not heated locally. Accordingly, even if the frequency of being used in the valve open state is high, the heat load of the whole valve part 14a is small, and the valve part 14a is heated almost uniformly, which results in improving the oxidation resistance and corrosion resistance of the valve part 14a.
