Abstract:
The present invention can be operated with excellent operability to prevent an opening/closing operation when unnecessary by automatically locking a rotating handle and to release the lock with one touch, while maintaining overall compactness by means of a simple internal configuration. A one-touch lock valve comprises: a valve main body (1) in which a valve element (4) is installed; a stem (3) axially mounted in the valve main body; a rotating handle (6) affixed to the upper part of the stem; a retaining body (21) accommodated in the rotating handle and secured to an axial mounting part (11); and a lock mechanism (10) arranged on the retaining body and the rotating handle. The lock mechanism comprises: a spring (33) mounted in the retaining body; a spherical body (40) provided on the lower force exertion side of the spring; a locking member (25) an intermediate portion of the rear-end side of which is axially mounted on the retaining body, a rear-end portion being elastically biased via the spherical body, and a front-end-portion side making elastic contact with a lower-edge portion of the rotating handle; and an engagement groove (23) in which the front-end-portion side of the locking member is engaged by the rotating handle. The locking member locks automatically in the elastically biased state at a position facing the engagement groove.
