摘要： The valve assembly is designed for isolation of the fluid in a storage tank from a diaphragm seal (29) of a level monitoring system. The assembly has a cleaning port (54) defined in the housing for directing cleaning or calibration fluid at the diaphragm seal so that it can be cleaned or calibrated in-situ . A flushing drain port (55) is provided to allow used cleaning fluid and dirt to be directed from the assembly. The invention eliminates the need to remove the seal and a pressure transmitter each time cleaning or calibration is required.
摘要翻译：阀组件设计用于将储罐中的流体与液位监视系统的隔膜密封件（29）隔离。组件具有限定在壳体中的清洁端口（54），用于在隔膜密封件处引导清洁或校准流体，使得其可以原位清洁或校准。提供冲洗排放口（55）以允许使用的清洁流体和污物从组件引导。每次清洁或校准时，本发明不需要去除密封件和压力变送器。

摘要： A ball valve assembly comprises a housing with ball valve (7) rotatably disposed in a valve chamber in the flow passage. The ball valve (7) is rotatable between open and closed positions by a valve stem that is connected to the ball valve at one end. The ball valve has an open ended slot (21) in wich the end of the stem (20) is received. During assembly the stem may be inserted into the housing first and then the ball valve introduced into the housing with the slot facing the stem and then moved in the direction of the slot so that that the stem is received in the slot. The arrangement enables the conventional bonnet a ball valve assembly to be eliminated and therefore provides for a compact design.
摘要翻译：球阀组件包括具有可旋转地设置在流动通道中的阀室中的球阀（7）的壳体。球阀（7）可在打开和关闭位置之间通过阀杆在一端连接到球阀上。球阀具有开口的狭槽（21），其中杆（20）的端部被接收。在组装期间，杆可以首先插入到壳体中，然后将球阀引入到壳体中，其中槽面向杆，然后沿槽的方向移动，使得杆被容纳在槽中。该布置使传统的阀盖能够消除球阀组件，因此提供了紧凑的设计。

WO2004085892A1 AN ISOLATION VALVE ASSEMBLY 审中-公开

摘要： An isolation valve assembly for use in a pipeline comprises a valve housing body (1) with a passageway extending therethough. A valve chamber (3) in said passageway receives a rotary valve ball (2) and a pair of valve seats (6, 7) disposed on opposite sides of the ball (2). Each seat (6, 7) has a first side proximal the ball valve (2) that defines a sealing surface in contact with an outer surface of said valve ball (2) as well as a second sealing surface in contact with the body. A passage (18) extending from the valve chamber (3) redirects fluid pressure in said chamber towards the side of the seat that is furthest from the valve ball (2) so that the fluid pressure can be used to force the seal into contact with the valve ball. The arrangement ensures that if the upstream seat seal fails the fluid that leaks into the valve chamber (3) is used to increase the sealing force applied between the downstream seat seal and the valve ball (2).
摘要翻译：用于管道的隔离阀组件包括具有沿其延伸的通道的阀壳体（1）。所述通道中的阀室（3）容纳旋转阀球（2）和设置在球（2）的相对侧上的一对阀座（6,7）。每个座（6,7）具有靠近球阀（2）的第一侧，其限定与所述阀球（2）的外表面接触的密封表面以及与主体接触的第二密封表面。从阀室（3）延伸的通道（18）将所述腔室中的流体压力重新定向到距离阀球（2）最远的座椅的侧面，使得流体压力可以用于迫使密封件与阀球。该布置确保如果上游座圈密封件失效，则泄漏到阀室（3）中的流体用于增加施加在下游阀座密封件和阀球（2）之间的密封力。
