Title:
クリーニング手段を有する温度応動弁
Document Type and Number:
Japanese Patent JP7104572
Kind Code:
B2
Abstract:
To provide a temperature responsive valve with cleaning means which comprises a simple configuration and is capable of surely removing a foreign substance at a downstream side of a valve port (valve hole) without leaking a fluid such as a drain.SOLUTION: Cleaning is performed by removing a foreign substance deposited within a valve seat downstream chamber 63 which is positioned at a downstream side of a valve port 62, by means of a downstream blade 8 through a screwing operation of a regulating rod 35. Namely, When a tool such as a driver is fitted into an operation groove 35c of the regulating rod 35 and the regulating rod 35 is unfastened, a valve shaft 10 per se rises in a direction of an arrow 105 while being rotated via a coupling rod 10a, and the downstream blade 8 is rotated proximately to an inner surface of the valve seat downstream chamber 63 via a valve body 2 and a center rod 4. Thus, the foreign substance deposited on the inner surface of the valve seat downstream chamber 63 is scraped off by the downstream blade 8.SELECTED DRAWING: Figure 1
