摘要： A combined stop-cock chamber and surface box comprises a plastic tube in two parts 10,11. The upper part 11 forms a surface box and is telescopically attached to the lower part 10 which houses the stop-cock. The two parts can be resiliently supported on a plastic plate to allow the surface box to be depressed resiliently by a load such as a vehicle wheel.
A ball valve housing 20 is moulded in the lower part 10 to prevent back siphonage.摘要翻译： 组合的止动阀室和表面箱包括两个部分10,11中的塑料管。 上部11形成表面盒，并且可伸缩地附接到容纳停止旋塞的下部10。 两个部件可以弹性地支撑在塑料板上，以允许表面盒通过诸如车轮的负载弹性地压下。 球阀壳体20模制在下部10中以防止反虹吸。

摘要： A valve spindle has a valve washer 59 at a lower end which acts as a valve closure member. The spindle is in two parts connected by a spigot and recess joint 62 which prevents rotation of the washer 59 in the valve seat when the upper part of the spindle is rotated to open or close the valve. Further seals 57,58,58a may be provided on both spindle parts.
摘要翻译： 阀芯具有位于下端的阀垫圈59，其用作阀关闭构件。 主轴由两个部分连接，这两个部分通过一个插口和凹槽接头62连接起来，当轴的上部旋转以打开或关闭阀门时，该接头62可防止垫圈59在阀座中旋转。 另外的密封件57,58,58a可以设置在两个主轴部件上。

摘要： The fluid valve arrangement for use in pipe work systems such as central heating systems, fire sprinklers, flowmeters, filters etc. comprises a valve body (1) which has a normally plugged aperture containing a removable plug (7).
The valve body (1) is adapted to receive a hollow plug (6) which is inserted through the normally plugged aperture.
To enable the hollow plug (6) to be inserted whilst the valve body is connected to a source of fluid pressure a gate valve (13) is used together with a domed housing (11) which contains the plug (6).摘要翻译： 用于诸如中央加热系统，消防喷洒器，流量计，过滤器等的管道工作系统中的流体阀装置包括阀体（1），其具有包含可移除塞（7）的通常孔的孔。 阀体（1）适于容纳穿过正常堵塞孔的中空塞子（6）。 为了使中空塞（6）在阀体连接到流体压力源时被插入，闸阀（13）与包含塞子（6）的圆顶壳体（11）一起使用。
