Title (EN) SAFETY LOCKING ARRANGEMENT
(FR) DISPOSITIF DE VERROUILLAGE DE SURETE
Abstract: front page image
(EN)A safety locking arrangement is provided on a valve for control of fluid flow comprising a valve body (1) having a seat (2) with a flow passage passing therethrough and a valve closure member (16) located within the body. The valve closure member is adapted to engage the seat to effect closure of the valve. The valve closure member is carried by a cap (10) adapted to enter into screwthreaded (3) engagement with the valve body at the mouth thereof. To ensure retention of the cap on the body, the cap additionally enters into screw-threaded engagement with an annular retaining means (20) disposed around and formed separately from the valve body, with the valve body itself being so formed in the mouth region that the retaining means cannot be withdrawn therefrom merely by rotation and/or displacement lengthwise of the valve body.
