Abstract
An apparatus for valve-seat inspection and pressure-resistance inspection for valves which can successively perform a valve-seat inspection and a pressure-resistance inspection on a valve and can quickly and correctly inspect valves, by highly-accurately detecting a leak of search gas in a substantially fixed time; a method for these inspections; and a valve. The apparatus allows a valve-seat leak and pressure-resistance inspection of a test valve, includes a clamp mounting mechanism that fixes the test valve in an inspection chamber, an inspection space adjustment mechanism that adjusts a volumetric capacity of an inspection space S of the chamber, and a gas sensor for valve-seat inspection arranged in a flow path of the test valve and a gas sensor provided in the chamber for a pressure-resistance inspection of the valve, in which the volumetric capacity of the inspection space S of the chamber is adjusted to be substantially fixed.
