Claims

[Scope of utility model registration request]

A short bottomed cylindrical valve housing with an open top, an inlet on the bottom and an outlet on the side, and a clamp that is removably attached to the open opening on the top of the valve housing, and both the top and bottom are closed on the top. A lid body with a vertical cylinder erected, a short vertically oriented tubular bearing intersecting the part of the lid body corresponding to the inlet, and an upper half sliding into the lower half of the bearing. A valve stem that is freely and airtightly inserted and has a valve body at its lower end; a flange-shaped portion that is smaller in diameter than the upper opening provided on the outer periphery of the valve body;
A valve seat is provided on the upper surface of the incisal edge of the inlet, and a female screw is provided that passes vertically through the upper wall of the vertical cylinder, and a male screw is screwed into the female screw, and a deep guide hole is formed in the lower surface of the male screw. an adjustment screw device provided, a guide rod whose upper end is slidably inserted into the guide hole and whose lower end is slidably inserted into the upper half of the bearing, and a portion near the upper end of the guide rod that moves up and down along the guide rod. The movable spring holder is fitted in this state, and the fixed spring holder is installed near the bottom end of the guide rod so that it cannot move up and down. These are equipped with a coil spring sandwiched between a movable spring holder and a fixed spring holder, and the height of the movable spring holder can be changed arbitrarily using the male screw mentioned above, and the lower end of the guide rod always holds the upper end of the valve rod. A safety valve characterized in that it is in a depressed state.
