Title:
クリーニング手段を有する温度応動弁
Document Type and Number:
Japanese Patent JP7261031
Kind Code:
B2
Abstract:
To provide a temperature responsive valve having cleaning means capable of surely removing foreign matter on a downstream side of a valve port (valve hole).SOLUTION: A cleaning rod 5 is operated to scrape off foreign matter adhering to the inside of a valve seat downstream chamber 63 located downstream of a valve port 62, by a downstream blade 2 formed at the tip of the cleaning rod 5. That is, a tool such as a screwdriver is inserted into an operating groove 35c of the cleaning rod 5, and when the cleaning rod 5 is tightened, the downstream blade 2 rises in a direction of an arrow 105 while rotating, and scrapes off foreign matter adhering to a ceiling slope 63a and a side wall 63b of the valve seat downstream chamber 63. Since the downstream blade 2 has a shape corresponding to the shape of the inner wall of the valve seat downstream chamber 63 and the shape of a valve body 12 protruding from the valve port 62, the foreign matter can be reliably removed.SELECTED DRAWING: Figure 1
