A metal plate having a substantially U-shaped cross section and consisting of a partially arc-shaped lower part 11 that slides on the cylindrical side surface 16 of the lid 3 in conjunction with the rise and fall of the lid 3, and an intermediate part 12 that connects the upper and lower parts. 4, the metal plate 4 is provided with a protrusion 9 bent in the opposite direction to the lower part 11 of the metal plate, and the protrusion 9 is attached to the valve box 6 or the valve box 6 at an appropriate valve opening position. The upper edge 14 of the long hole 13 of the stop plate 8 engages with the long hole 13 of the stop plate 8 provided so as to be fixed to the corresponding part and slides in the axial direction of the valve stem.
A valve characterized in that the valve is brought into contact with the valve to constitute a valve opening degree limiting mechanism. (2) A folded part 20 having a U-shaped cross section is provided on the upper part of the stop plate 8, and the folded part 20 is configured to engage and slide on the side edge 21 of the intermediate part 12 of the metal plate. The valve described in paragraph (1). (3) Claim (1) characterized in that an opening degree scale 15 is disposed on the cylindrical side surface 16 of the lid and engages with the lower part 11 of the metal plate to serve as a valve opening degree display device.
) or claim (2). (4) In a valve stem rising type valve that restricts the flow rate by rotation of the handle wheel 2, a portion of the valve stem 1 that has an insertion hole 10 for the valve stem 1 and is connected to the lower part of the handle wheel 2 rotates. The upper part 17 held freely and the valve stem 1
A metal plate having a substantially U-shaped cross section and consisting of a partially arc-shaped lower part 11 that slides on the cylindrical side surface 16 of the lid 3 in conjunction with the rise and fall of the lid 3, and an intermediate part 12 that connects the upper and lower parts. 4, a part of the valve box 6 or a part similar to the valve box 6, and the intermediate part 1 of the metal plate.
2. A valve characterized in that holes 18 and 19 are provided in a part of the valve opening, and a valve opening degree limiting mechanism is configured that can be sealed using a steel wire or the like. (5) An opening degree scale 15 is disposed on the cylindrical side surface 16 of the lid and engages with the lower part 11 of the metal plate, thereby serving as a valve opening degree display device.
