記載の二重シール弁。[Claims for Utility Model Registration] (1) An upper valve seat and a lower valve seat are formed in a vertical passage communicating between two upper and lower liquid flow paths, and an upper valve body and a lower valve body respectively correspond to these two valve seats. and are disposed coaxially and oppositely to the passage and to form an opposing gap between both valve bodies when the valve is closed, and the lower valve body has a first valve rod extending upward and a first valve rod extending upwardly, and a first valve rod extending upwardly, and a first valve rod extending upwardly, and a first valve rod extending upwardly, and a first valve rod extending upwardly, and a first valve rod extending upwardly, and a first valve rod extending upwardly, and a first valve rod extending upwardly, and a first valve rod extending upwardly, and a first valve rod extending upwardly, and a first valve rod extending upwardly, and a first valve rod extending upwardly, and a first valve rod extending upwardly. A drain pipe is formed in communication with the drain pipe extending downward, and the upper valve body is formed with a hollow second valve rod that is externally inserted into the first valve rod, and the upper valve body is connected to the lower valve body. In the double seal valve that moves following the drain pipe, the lower end of the drain pipe is biased upward by a spring force to liquid-tightly seal the lower end opening of the drain pipe, and the liquid in the drain pipe is biased upwardly by a spring force. A double seal valve characterized in that it is provided with a drain valve that descends and opens when the weight overcomes the spring force, and a proximity switch that detects the opening operation of the drain valve. (2) Both valve rods of the upper and lower valve bodies protrude outward from the upper part of the valve casing that constitute the upper and lower liquid flow passages, and a cleaning liquid passageway reaches the opposing gap between the two valve bodies from the cleaning liquid inlet provided in this protrusion. Formed claim (1)
Double seal valve as described.
