Claims (1)
力感知板により弁機構が制御作動を行なう減圧弁
の弁箱に設けられる前記２次圧室の接続筒部の開
口端部に、その接続口の径方向に延出する取付鍔
部を形設し、その取付鍔部を、ボイラーの罐体の
罐壁に開設した水取入口の回わりに組付け止着し
て、罐体の罐壁に弁箱を直結的に組付け接続せし
めたことを特徴とするボイラーにおける減圧弁。 At the open end of the connecting cylinder part of the secondary pressure chamber provided in the valve box of the pressure reducing valve, the valve mechanism performs a control operation by a pressure sensing plate that operates based on the difference between the pressure on the secondary pressure chamber side and the spring pressure, A mounting flange extending in the radial direction of the connection port is formed, and the mounting flange is assembled and fixed around the water intake hole provided in the can wall of the boiler casing. A pressure reducing valve for a boiler, characterized in that a valve box is directly assembled and connected to a can wall.
