Abstract (en)
A wrench socket (1) is disclosed for a hydrant valve (B) that is provided with a body ( co ) having symmetrically opposed sides ( la ), a stem ( st ) and a handwheel ( vo ). The socket (1) comprises a front part (2) having a curved wall (20) provided with an opening (21) and inner surface (23), a rear part (4) for its coupling with a wrench and an intermediate part (3) joining the front part (2) to the rear part (4). The intermediate part (3) has an inner cavity (30, 31) designed to receive the stem ( st ) without the handwheel ( vo ) when the socket (1) is inserted on the valve (B), and the inner surface (23) is a continuous surface tangent to the symmetrically opposed sides ( la ) of the body ( co ) so that the socket (1) inserted on the valve (B) exerts a torque on the body ( co ) by means of the wrench for screwing or unscrewing the valve (B).
