闸门阀具有阀壳体（1），是在主轴（2）关闭楔（3）容纳的可操作之一。 滑动壳体（1）由一个向内突出的壳体轮缘设置有（6）经Absperrkeils的外轮廓为界（3）适于将所述上壳体的开口（7）被提供，其由所述外壳边缘（6），盖（11）从所述卡合后面内的压力密封 已完成。 盖（11）携带的外，内螺纹的颈部（13），其中，具有用于所述主轴（2）为主轴套环的导向件（35）和密封件（40）和支撑支座（36）（21）具有锁定螺钉（14）拧入 是。 覆盖件（13）和闭合螺钉（14）被插入的支承环（15）坐在两个支撑脚之间（16），其从上述坐起来在外壳的边缘（6）。 当拧紧锁定螺钉（14）由主轴套环（21）被夹紧和密封，所述主轴（2）和也盖（11）是压力密封地连接到所述外壳（1）支撑。 盖连接件（13）是大致壳体开口（7），其适于与所述锁定螺钉（14）的凹部内用于支撑主轴套环（21）和外侧，一个连续的外螺纹（22）的宽度。

The gate valve has a valve housing (1), is in the one of the spindle (2) actuable shut-off wedge (3) housed. The slide valve housing (1) is matched with a by an inwardly projecting housing rim (6) bounded by the outer contour of the Absperrkeils (3) the upper housing opening (7) which engages behind by the housing edge (6), cover (11) from the inside a pressure-tight is completed. The cover (11) carries an outer internally threaded socket (13), in a one guide (35) and seal (40) for the spindle (2) and a support abutment (36) for the spindle collar (21) having locking screw (14) screwed is. Between the cover piece (13) and the plug (14) is a support ring (15) inserted, seated at the two support legs (16) that sit up on top of the edge of the housing (6). When tightening the locking screw (14) by the spindle collar (21) is clamped and sealed, the spindle (2) and also the cover (11) is pressure-tightly connected to the housing (1) braced. The cover connection piece (13) is approximately the width of the housing opening (7) is adapted and the locking screw (14) carries internally a recess for supporting the spindle collar (21) and the outside, a continuous outer thread (22).
