摘要： Pressure relief apparatus for ensuring that the pressure of fluid in a vessel does not exceed a known maximum value, comprising a bursting disc assembly (10) together with a pressure relief valve means (40), there being a sealed interspace (76) between the assembly (10) and the valve means (40). The apparatus also includes indicator means (56,74) for indicating when the pressure in said interspace (76) reaches a first known minimum value, while said valve means. (40) includes secondary relief valve means (54) which permit flow of fluid therethrough from the interspace (76) when the pressure in said interspace (76) reaches a further known value at least equal to said first known value but less than said known maximum value, and primary relief valve means (46) which permit flow of fluid therethrough from the interspace (76) when the disc (12) of the assembly (10) bursts. Preferably the primary and secondary relief valve means (46,54) and the indicator means (56,74) are incorporated in a single valve unit (40).

摘要： A valve comprises a valve housing (10),an annular valve seat (12) and a valve closure plate (14) having a deformable annular seal (52), the valve being operable from a first, closed condition in which the valve closure plate (14) engages the valve seat and into a second, open condition in which the valve closure plate (14) is displaced from the valve seat. The valve closure plate (14) comprises first (14a) and second (14b) portions which are releasably securable together to retain the deformable seal (52) on the valve closure plate and the second portion (14b) of the valve closure member is removable with the valve in the closed condition to allow removal and/or replacement of the deformable seal (52).

摘要： A handle assembly for operating a valve of the type having a valve body and a pivotally mounted actuating spindle (22) extending from the valve body has a mounting means (12) to secure the assembly to the spindle (22), a handle portion (14) connected to the mounting means and a pivotally mounted locking member (28). The locking member is pivotable, either by camming surfaces on the handle portion and the locking member or by a key, between a first locked position in which it engages with a portion of the valve body, and a second, unlocked position in which it is free from the valve body and enables the valve spindle to be rotated by the handle portion. The locking member (28) is provided with a number of apertures which can be aligned with corresponding apertures in the mounting means (12) and the handle portion (14) when the locking member is in the locked position. The apertures are shaped to receive tamper-sensitive tape or wire or the shackle of a padlock, to indicate or prevent unauthorised use of the valve.

摘要： A valve is in the form of a valve body (10) having a valve inlet (26), a valve outlet (28) and a valve seat (16) disposed between the inlet and the outlet. A valve closure member (12) is movable between a first, closed position in abutment with the valve seat (16) and a second, open position in which it is displaced from the valve seat (16).
A shaft (70) is pivotally mounted within the valve body (10) and one end is connected to an actuating handle (14), by means of which it is pivotable. An arm (54) is connected to the shaft (70) and to the valve closure member (12), whereby movement of the actuating handle (14) causes opening and closing of the valve.
The positioning of the pivoting portions of the valve and the spring within the valve body (i.e. in an aperture actually within the material forming the valve body) means that the only item other than the valve closure member in the path of material being discharged is the arm (54), and that when in the open position the valve closure member causes no constriction of the bore.摘要翻译： 阀门为具有阀入口（26），阀出口（28）和设置在入口和出口之间的阀座（16）的阀体（10）的形式。 阀关闭构件（12）可在与阀座（16）邻接的第一闭合位置和与阀座（16）移位的第二打开位置之间移动。 轴（70）枢转地安装在阀体（10）内，并且一端连接到致动手柄（14），借助于此可枢转。 臂（54）连接到轴（70）和阀关闭构件（12），由此致动手柄（14）的移动导致阀的打开和关闭。 阀门和弹簧的枢转部分在阀体内的定位（即在实际上在形成阀体的材料内的孔中）的定位意味着在被排出的材料路径中除阀闭合构件之外的唯一项目是 臂（54），并且当处于打开位置时，阀关闭构件不引起孔的收缩。

摘要： A valve assembly has a valve body (10) which houses a pivotally mounted valve closure member (14) in the form of a valve closure flap secured to upper and lower spindles (16, 17). The valve housing is formed from two sections (20, 22) which are releasably secured together by means of an annular clamp (24) which engages with a peripheral upstanding rib (36) formed by the alignment of a flange (34) on one face of each of the valve housing sections.
The valve closure member is located in the vicinity of the junction of the two valve housing portions. The provision of a clamp permits the valve assembly to be dismantled extremely quickly in the event of service or repair of the valve assembly.摘要翻译： 阀组件具有阀体（10），阀体（10）容纳枢转地安装的阀闭合件（14），该阀闭合件呈固定在上部和下部心轴（16,17）上的阀关闭片的形式。 阀壳由两个部分（20,22）形成，两个部分通过环形夹子（24）可拆卸地固定在一起，该环形夹子（24）与在一个面上的凸缘（34）对准形成的周边直立肋（36） 的每个阀壳体部分。 阀关闭件位于两个阀壳体部分的连接处附近。 提供夹具使得在维修或修理阀组件时可以非常快速地拆卸阀组件。
