Claims

[Scope of utility model registration request]

On the inner surface of the valve stem 6, a female thread 8 and an R-shaped sealing surface 9 are provided sequentially from below, and the vertical positional relationship is reversed from the valve opening shape of a normal valve stem at the deep part of the sealing surface. An opening 10, a female thread 11, a V-shaped tapered surface 12, and a small opening 13 are formed as shown in FIG. is formed to provide a spring locking portion 17,
A pipe-shaped body packing 18 is attached to an intermediate position on the outer surface, and a disc-shaped flange 19 is provided slightly below the body packing 18, and a valve port 20 is provided at the lower end with a slightly thinner wall. The straight opening 15.16 is provided with:
A shaft 23 to which a cylindrical valve seal 21 and a valve seal receiver 22 are caulked and fixed is inserted, and a compression spring 24 is inserted from above the shaft.
After inserting, the upper end of the shaft 23 is fixed by caulking to keep the valve port 20 airtight, and from the lower end of the shaft, the window 26 formed by slotting and the female thread of the valve stem are inserted. After inserting the head 25 having a male thread 2'7 that can be screwed into the valve core 7, the skirt portion 28 of the head is caulked and fixed to the flange 19 of the valve core body.
A high-pressure valve comprising: a valve core 7 screwed into the stem 6 from below to be fixed therein;
