发明名称 Anordning för avstängningsventil i mark
摘要 An arrangement intended for a stop valve (1) comprises a tubular member (9). The stop valve (1) is located in the ground (2) and has a valve housing (11) and a valve bonnet (12) fixed thereto with the aid of a fixing means (14), said valve bonnet having a valve spindle (15) supporting a movable stop means (16), such as a slide. The tubular member (9) extends from the valve (1) up to ground level to enable operation of the valve spindle (15). A collar means (10') is tightly connected with and supported by the valve housing (11). The collar means (10') has a collar portion (32) which surrounds the valve bonnet (12) and the fixing means (14) and is tightly connected with the lower end of the tubular member (9), the diameter of the tubular member (9) essentially corresponding to the diameter of the collar portion (32). Moreover, the arrangement comprises a pipe access means (12'), which instead of the valve bonnet (12) from ground level is tightly mountable on said valve housing (11).
