Abstract
PURPOSE: To easily control coupling at a water seal portion by providing a moving clearance as an enclosed empty chamber formed at the side which is in contact with a coupling adjustment mechanism for water seal valve seat and by installing a pressurized fluid intake circuit in the empty chamber.
CONSTITUTION: A stop valve 25 is installed at a liquid pressure intake pipe 24. When the stop valve 25 is opened, the fluid at pressure P on the upper stream side is introduced into an enclosed empty chamber 23 through the intake pipe 24. and presses a water seal valve seat 19 at the pressure P all over the section of height L2 in the direction opposite to a fluid passage direction S. The pressure P acts on the section of height L1 from the upper stream side of the fluid along the fluid passage direction S. The water seal valve seat 19 is pressed down into the coupling direction to a valve body 17 at the force of P×(L2 -L1). The action force of said fluid increases the tightness between the water seal valve seat 19 and the valve body 17. The water seal valve seat 19 follows any localized deformations of the valve body 17 and provides a uniform water seal effect over the entire water seal portion.
