Claims

[Scope of utility model registration request]

A pressure detection plug that measures the fluid pressure in the flow path 1 by being screwed into a female threaded hole 3 formed through a side wall 2 of the pressure fluid flow path 1, and a male screw threaded into the female threaded hole 3. A plug body 4 having a portion 4A and a pressure measurement hole 4B;
A screw shaft portion 5A that can be screwed into the outer end portion of the pressure measurement hole 4B, and a state in which the screw shaft portion 5A is screwed into the pressure measurement hole 4B as much as possible, seal and close the pressure measurement hole 4B. A bolt-like valve body 5 having an overhanging head 5B, and a bolt-shaped valve body 5 having an overhanging head 5B, at least one location in the circumferential direction on the circumferential surface of the helical shaft portion 5A of the bolt-like valve body 5, over the entire length or almost the entire length in the axial direction. A pressure detection plug characterized in that it has a flat portion 5a with a thread removed.
