Pressing on. The inner surface of the lower end portion of the peripheral wall 2 is formed in a tapered portion having a small diameter at the lower side, and is provided so that the gap between the lower end of the valve head 13 and the inner surface of the peripheral wall can be changed by the vertical movement of the valve head 13.

Numeral 20 denotes a valve displacing means which forms the outer end of a plate-like lever 21 placed on the top wall of the cylinder lid 5 in a gripping portion and cuts off the center of the inner end to form a forked shape. And, the shaft 22 is laid across the forked portion. Then, the shaft 22 is
It is rotatably fitted into a cutout portion 23 of a side opening formed at the upper end of the valve stem 14.

As shown in FIG. 3, a recess 24 is formed on the upper surface of the top wall of the tubular lid 5 by erecting the lever 21 so that the tip of the bifurcated portion of the lever can be fitted. 4 and 5
Shows another embodiment, in which a semicircular raised portion 25 is formed on the upper surface of the peripheral portion of the top wall of the cylindrical lid 5 so as to be able to ride on by rotating the lever 21 in the circumferential direction.

Reference numeral 30 denotes a connecting member for fitting an outwardly-flanged tube 31 to the inner surface of the inflow tube 4 of the valve housing, and an inwardly-flanged female screw tube 32 to the outer surface of the inflow tube 4.
Flange holes are slidably fitted. To attach the valve housing 1 to the discharge pipe 34 of the container 33, the female screw pipe 32 may be screwed to the outer surface of the discharge pipe 34.

Next, the operation of the present embodiment will be described.
FIG. 1 shows a fully closed state of the flow control valve. To open the valve, the outer end of the lever 21 may be lifted, and the inner end of the lever slides on the upper surface of the top wall of the cylindrical lid 5 to raise the valve body 14 against the urging force of the coil spring 16. . To fully open,
As shown in FIG. 3, the lever 21 may be raised and the inner end may be fitted into the recess 24.

In order to close the valve, the lever 21 may be pulled forward from the state shown in FIG. 3, and the inner end of the lever is detached from the concave portion 24 and falls down on the top wall of the cylinder lid 5, and the valve body 12 is closed. Is pressed down by the spring force and comes into contact with the valve seat 11. On the other hand, in order to reduce the flow rate by setting the valve opening to the middle, the lever 21 may be rotated in the circumferential direction to ride on the raised portion 25 as shown in FIG. The broken line in FIG. 1 shows the position of the valve head 13 at this time.
