摘要： A gate valve comprises a valve body having an internal working fluid passage and an internal gate chamber extending transverse to the working fluid passage. In addition, the gate valve comprises a gate disposed in the internal gate chamber and movable within the gate chamber between a closed position obstructing fluid flow through the working fluid passage and an open position allowing fluid flow through the working fluid passage. Further, the gate valve comprises an internal sealing arrangement coaxially disposed in the working fluid passage and extending between the valve body and the gate to form a barrier between the internal working fluid passage and the gate chamber. The internal sealing arrangement includes a frustoconical metal sealing surface adapted to sealingly engage an opposed mating frustoconical metal sealing surface on the valve body to form a first tapered metal-to-metal seal between the sealing arrangement and the valve body.

摘要： A double check valve (10) with two separate elements (20, 25) individually movable to close the valve and collectively movable to open the valve. The separate elements are independently closing the valve, and collectively controllable to open the valve, to allow pressure release or to allow injection of fluid (e.g. lubricant). In an example, the double check valve includes two separate check valves with a stinger element (30) between them which is operable to internally sting the one check valve when (e.g. by action of) the other check valve is stung by a user (e.g. using a stinger means) thereby to open both check valves individually and the double check valve as a whole.
摘要翻译：具有两个独立元件（20,25）的双止回阀（10），其可单独移动以关闭所述阀并且可共同地移动以打开所述阀。单独的元件独立地关闭阀，并且可共同控制以打开阀，以允许压力释放或允许注入流体（例如润滑剂）。在一个示例中，双止回阀包括两个单独的止回阀，在它们之间具有托架元件（30），当止动阀（例如通过动作）另一个止回阀被用户拴住时，该止回阀可操作以在一个止回阀内部固定（例如，使用托管装置），从而单独打开止回阀和整个双重止回阀。
