The present invention relates to a waterproofing port for an indoor fire hydrant valve, and more particularly, an angle valve that is embedded in a fire hydrant box in an indoor fire hydrant facility and used to open and close the fire extinguishing water. It relates to a waterproof port for an indoor fire hydrant valve in which the coupling of the valve is secure and the coupling of the valve rod is firm and accurate.
The present invention is a valve body provided with a valve seat between the inlet and the outlet, and a valve that is rotatably screwed to a support boss protruding from the inside of the valve body in the direction of the valve seat to vertically move upward and downward according to the rotation. Consisting of a rod and a valve body coupled to a packing at a lower end of the valve rod;
The valve rod includes an integral coupling protruding ring in which the coupling surface and the rod coupling groove are coupled in a concave-convex shape, and one or more tightening reinforcing grooves are formed on the support surface to provide a clearance with the coupling portion;
The rod coupling groove to which the coupling protruding ring is coupled and the locating groove and the screw coupling part are formed in the upper inner diameter of the support body of the bottom, and a pressurizing support part is formed radially, and the support body is inclined toward the upper side from the outer diameter of the part with the fixing groove. The lower side includes a valve body having a small outer diameter and becoming larger toward the upper side;
A fixing ring that forms a fixing screw that is coupled to the screw connection part at the outer diameter of the valve rod and is coupled to the screw connection part, and the valve rod is rotatably connected to each other;
It is characterized by comprising a packing that surrounds the valve body and is coupled to a fixing groove at the upper side of the packing body, is integrally fixed with a coupling protrusion at the tip of the radial pressing part at the circumference of the packing body, and has a blocking part formed at the lower side.
