している(特願昭60−106553号参照)。(Prior Art) Generally, various valves built into piping equipment such as water supply and hydraulic equipment have operating handles that protrude from the outside of the valve housing. A valve body inside the housing is actuated to shut off or adjust the flow rate of fluid in the piping. This type of valve structure requires a large space for the operating handle, making it unsuitable for complex piping equipment that requires space saving. A suitable valve structure has already been filed (see Japanese Patent Application No. 106553/1982).

の弁体5を操作リング3の操作量に応じて回動させる。In this device, as shown in Fig. 3.4, an exterior ring 2 rotatably fitted around the outer circumference of a valve housing 1 is manually rotated around an axis (X-X line in the figure). Then, the operating ring 3 connected to the exterior ring 2 rotates integrally, and the pinion gear 4 meshed with the rack teeth 3a of the operating ring 3 is driven. The pinion gear 4 is pivotally supported by the valve housing 1 with the Y-Y line orthogonal to the X-X line as the center of rotation, and the spherical valve body 5 housed in the valve housing 1 is controlled by the operating amount of the operating ring 3. Rotate accordingly.

弁構造となっている。When the valve hole 5a formed in the valve body 5 communicates with the flow hole 7 formed by the valve housing 1 and the pair of valve seats 6, fluid (not shown) flows from the pipe PA to the pipe P. That's what I do. That is, a ball valve 8 consisting of a valve body 5 and a valve seat 6 is opened and closed by an operating force from an operating ring 3 via a pinion gear 4, and an operating handle etc. that protrudes from the valve housing 1 to the outside is opened and closed. This valve structure is suitable for saving space in piping equipment.

用途する弁構造としては不経済なものであった。(Problems to be Solved by the Invention) However, in such a conventional valve structure, the operating force received by the outer ring 2 is transferred to the rack teeth 3 of the operating ring 3.
A and the pinion gear 4 change the direction and transmit the information to the valve body 5. Although the valve structure is compact and saves space, the cost of machining the operating ring 3 and the pinion gear 4 is high. Ta. In addition, since the tooth shape shown in FIG.
Since teeth are formed over the entire circumference of the valve, it is not possible to determine the position at which the valve opening is fully open or fully closed using only the operating ring 3 and pinion gear 4. Therefore, it is necessary to determine the opening/closing position using another means, which is particularly uneconomical for a valve structure whose main purpose is to shut off fluid.

になっている。Reference numeral 21 denotes a cylindrical operating member, and the operating member 21 is rotatably attached to the outer periphery of the valve housing If substantially coaxially with the fluid passage I6. The operating member 21 includes an outer cylinder 22 and an inner cylinder 23 that are fixed to each other or integrally engaged in the rotational direction.
The outer periphery of the outer cylinder 22 is engraved with dovetail knurling and the like. A guide groove 23a extending in the axial direction is formed in the inner cylinder 23.
3a is a retaining pin 24a implanted in the valve body drive member 24.
is engaged. The valve body driving member 24 has an engagement pin 24a that is an engagement portion that engages with the operating member 21, and a support portion 24b that is rotatably supported by the valve housing 21 on the rotation axis of the valve body 18. The support portion 24b of the valve body driving member 24 is provided with a convex portion 24c that protrudes toward the valve body 18 side. The convex portion 24c of the valve body driving member 24 has, for example, a rectangular cross section, and is adapted to rotate integrally with the valve body 18 by being fitted into a recess 18b formed in the valve body 18. Then, when the operating member 21 is manually rotated as shown in the X-X diagram, the engagement pin 24a of the valve body driving member 24 slides into the guide groove 23a of the inner cylinder 23 according to the amount of operation of the operating member 21. When they come into contact with each other, the valve body driving member 24 rotates, and the valve body 18 is rotated along the YY line. Further, the valve body driving member 24 is rotated in a predetermined angle range (angle θ in FIG. 2) by the rotation operation of the operating member 21, and the valve body 18 is in the valve open position where it is fully open and the valve closed position where it is fully closed. In this position, the engagement pin 24a is connected to the circular wall surface 2 of the inner cylinder 23.
3b, and in this state, the valve body drive member 24 functions as a stopper that restricts rotation of the operating member 21. That is, the valve body 24 rotates within a predetermined angular range from the valve open position to the valve closed position, and drives the valve body 18 to open and close via the support portion 24b.

Moreover, 26 is a seal ring, and the seal ring 26 is interposed between the valve housing 11 and the support part 24b of the valve body drive member 24, and maintains the liquid tightness in the valve chamber 17.
次に、作用を説明する。Next, the effect will be explained.

開側あるいは弁閉側に駆動される。First, when the outer cylinder 22 of the operating member 21 is directly grasped and rotated around the axis of the fluid passage 16, the inner cylinder 22 of the operating member 21
3 rotates so that the guide groove 23a and the engagement pin 24a of the valve body drive member 24 come into sliding contact, and the valve body drive member 24 moves into the fluid passage 1.
It rotates around a rotation axis perpendicular to 6. At this time, the valve body 18 is driven via the support portion 24b of the valve body drive member 24, and the valve body 18 aligns the axis of the valve hole 18a with the valve hole 19 of the valve seat 19.
The valve holes 18a and 19a are rotated so as to intersect with the axes of the valve holes 18a and 19a, or to reduce the intersecting angle of the axes of the valve holes 18a and 19a. Therefore, the valve body 18 is easily driven to the valve opening side or the valve closing side by the valve body driving member 24 having a simple configuration having the engagement pin (engaging portion) 24a and the support portion 24b as both ends.

する必要がない。Next, by rotating the operating member 21, the valve body driving member 2
4 rotates to the valve open position or valve close position, the engagement pin 24a comes into contact with the circular wall surface 23b of the inner cylinder 23, restricting the rotation of the operating member 21, and the valve body 18 is fully open or fully closed. stop in the state. Therefore, simply rotating the operating member 21 facilitates opening and closing the valve, and furthermore, the valve open position and valve closed position are determined only by the engagement state of the inner cylinder 23 and the valve body drive member 24. , there is no need to provide a separate means for position determination.

であるということができる。In this way, in this embodiment, the valve body 18 is easily opened and closed using the valve body drive member 24 having a simple configuration, so the mechanism for driving the valve body is simplified and the parts cost is reduced. . In addition, since the valve open position or valve close position is easily determined by the valve body driving member 24, there is no need to separately provide means for determining the position when the main purpose is to shut off fluid, and it is extremely economical. It can be said that the valve structure is suitable for use as a fluid cutoff.

The present invention is not limited to this, and can be applied to other valves such as butterfly valves. Further, the valve body drive member is not limited to the shape shown in the drawings, and may be in the form of a link. It may also be engaged with a concave (including holes, slits, etc.) engaging portion or side surface of. Furthermore, the valve body driving member does not necessarily have to function as a stopper for the operating member; if the valve body is rotated within a predetermined angular range between the valve open position and the valve closed position, the operating member will rotate within the other range. A similar effect can be obtained even in a free state.
