Claims

[Scope of utility model registration request]

an external opening formed on the outer surface of an egg-shaped flange attached to the process flange of the transmitter;
A process side opening formed on the process flange side and communicating with the fluid to be measured, a through hole that linearly connects both of these openings, and a stepped portion formed near the process side opening on the inner periphery of this through hole. (valve seat), a threaded portion formed near the external opening on the inner periphery of the through hole, and an outflow hole formed in the through hole between the stepped portion and the threaded portion so as to communicate with the outside. , a valve body that is slidably inserted into the through hole from the external opening and has a tapered part formed at its tip contacting the stepped part to form a sealing part; and a valve body that is screwed into the threaded part. and tightening plug means for pressing the valve body against the stepped portion.
