In the valve, an engaging part 6a is formed in the upper part of the stem 6, and a lock pin 12 is formed in the valve box 1 on the side of the engaging part 6A.
When the ball valve body 3 is at a predetermined opening position, the lock plate 13, which has an insertion hole 13a in the center and a cutout groove 13b in the outer periphery, is inserted into the insertion hole 1.
3a and the engaging portion 6a, and the notch groove 13b and the lock pin 12 are respectively engaged and inserted into the stem 6, and the lock plate 13 is inserted into the lock nut 1.
4 to the stem 6, and the cap 15 is screwed onto the valve body 1 from above the lock nut 14 with an O-ring 9 interposed therebetween to prevent the lock nut 14 from loosening and to seal between the valve body 1 and the cap 15. A shutoff valve with a lock configured to perform this function. (2) The shutoff valve with a lock according to claim (1), wherein the seat ring 5 is made of synthetic resin, and the seat ring 5 is inserted into the valve chamber 1a with an O-ring 4 interposed therebetween. (3) An interlock mechanism A is interposed between the lock plate 13 and the cap 15, and by inserting the lock plate 13 into the stem 6, the interlock mechanism A is released and the cap 15 is connected to the valve body 1.
The shutoff valve with a lock according to claim 1, wherein the shutoff valve has a lock that can be screwed onto the valve. (4) The interlock mechanism A is attached to a lock pin 12 that stands up on the side of the engaging portion 6a of the stem 6 of the valve body 1.
and a lock lever 16 which is rotatably supported by the lock pin 12 and becomes horizontal due to gravity.
