作部の一定角度の回動により弁体を開閉する形式の弁操
作装置に関するものである。The most popular type of valve mentioned above is the lift valve.The operating mechanism of this lift valve is to rotate the valve shaft connected to the disc on which the valve disc is mounted. There are devices that move the valve toward and away from the valve seat, and devices that open and close the valve by moving the valve directly in the axial direction. Among the former type of valve operating device, the present invention is particularly directed to This invention relates to a valve operating device that opens and closes a valve body by rotating an operating part through a certain angle.
（従来技術及びその問題点）
この種弁操作装置としてすでに第６図のものが知られて

たカム筒ｃ１１１とカム対偶する。This Monoke uses a cam mechanism to raise and lower the valve shaft O1 as the drive shaft as it rotates, and the valve shaft 0
The bottle 1lll provided at α is mated with a cam cylinder c111 provided in the valve shaft penetrating portion of the device main body.

れる構成である。This cam cylinder has a pair of cam parts (2
) and ■, both ends of the bottle Oυ are in contact with each other from the upper blade, and the valve body 13) (i) is configured such that a biasing force in the valve closing direction is always applied to the valve body G++ by a spring +41 VC. It is.

1) moves from the valley part of ■ to the peak part of the cam part, and the valve stem (1)
0I and the valve body (3) are lifted to open the valve, and when both ends of the bottle 01) are fitted into the recesses provided in the peak, the valve is held in this open valve state.

位置に保持されるようにしたことである。(Means) - The technical means of the present invention for solving the problem described in 1-1 is to bias the pressing means in the pressing direction by means of a lever, and to move the drive shaft connected to the pressing means in the axial direction. In a device that opens and closes a lever that moves, a plurality of links are arranged on the outer periphery of the axis of the drive shaft on a cylinder or tapered surface that is concentric with this fine detail, and each of these links has both ends The first fulcrum is the upper piece provided on the drive shaft, and the second fulcrum is provided on the device body side, and these fulcrums allow two movements in the circumferential direction and f radial direction. The first part of the pair in the opening state. The distance between the second fulcrums in the direction of the drive shaft is set smaller than the distance between the fulcrums of the link, so that either one of the fulcrum groups can be rotated integrally at a certain angle, and the end of the rotation u when opening r. Each fulcrum of these fulcrum groups is held at a position near the dead center relative to the other fulcrum.
（作用） 本発明の」１記技術的手段は次のように作用する。(effect) The technical means described in item 1 of the present invention operates as follows.
初期状態では、各リンクの第１支点は第２支点から円周
方向に外れた位置忙あり、駆動軸及び弁押圧手段も初期
位置にあって、バネの付勢力によりｙｔ体は閉ｊｔ状態
に保持さｈている。In the initial state, the first fulcrum of each link is located circumferentially away from the second fulcrum, the drive shaft and valve pressing means are also in the initial position, and the yt body is in the closed state due to the biasing force of the spring. It is retained.

群の回動に伴って各リンクは円滑に揺動する。この間で
は、支点の対偶部がその姿勢を変えるだけであり、摺動
のない状態で動作が進行する。Next, when the first fulcrum group or the second fulcrum group is integrally rotated forward around the drive shaft, each link swings around the fixed fulcrum, and the I8# axis moves in the axial direction. It is moved and the valve body opens. During this rotation, each fulcrum has two degrees of freedom in the circumferential direction and the radial direction, so each link swings smoothly as each fulcrum group rotates. During this period, the pair of fulcrums only changes its attitude, and the operation proceeds without sliding.

り弁体が閉弁する。The fulcrum on the rotation side is automatically or forcibly locked at a position where the other fulcrum substantially coincides with the other fulcrum, that is, at a position near the dead center, and the valve is suddenly held in an open state. When the lock is released and the rotated fulcrum group is rotated in the opposite direction, the fulcrum group moves to the other fulcrum group and returns to its initial position, and the valve body closes due to the biasing force of the spring. do.
以−にのように、いずれか一方の支点群を一定範囲にわ
たって回動きせると弁体が開閉し、作用力変換機構さし
てのリンク機構がａＸ＃動作のない対偶開係により弁体
を開閉させる。As described above, when either one of the fulcrum groups is rotated over a certain range, the valve body opens and closes, and the link mechanism, which is the acting force conversion mechanism, opens and closes the valve body by the paired opening mechanism without aX# movement. .
（効果）
本発明は上記構成であるから、次の特有の効果を有する
。(Effects) Since the present invention has the above configuration, it has the following unique effects.
摺動部分がなく、リンクの支点を構成する対偶素の姿勢
変化のみにより？ｐ体の開閉動作が進行するから、一定
範囲の摺ｆＩ１１＃作に伴って開閉される操作機構にく
らべて動作が円滑になる。There are no sliding parts, and only the posture changes of the pair elements that make up the fulcrum of the link? Since the opening/closing operation of the p body progresses, the operation is smoother than that of an operating mechanism that opens/closes as the sliding fI11# moves over a certain range.
また、同じ理由から動作の抵抗が少なくなり、操作力が
軽減できる。Furthermore, for the same reason, the resistance to movement is reduced, and the operating force can be reduced.
