    • A gate valve assembly (100) for use in subsea workover systems is disclosed. In an embodiment, the gate valve assembly (100) includes a valve block (102). The valve block (102) includes a cutting gate (204) disposed in a valve cavity (206) such that the cutting gate (204) can engage in a reciprocating motion in the valve cavity (206) between an “open” position and a “closed” position. The reciprocating motion of the cutting gate (204) results in a cutting operation of a tubing conveyed string passing through the gate valve assembly (100). The gate valve assembly (100) further includes a slug pit (202) formed in the valve block (102) alongside the valve cavity (206). The slug pit (202) defines an opening which can contain one or more cuttings from tubing conveyed springs resulting from the cutting operation. The reciprocating motion of the cutting gate (204) transports one or more cuttings of the tubing conveyed string to the slug pit (202).
    • 公开了一种用于海底修井系统的闸阀组件(100)。 在一个实施例中,闸阀组件(100)包括阀块(102)。 阀块(102)包括设置在阀腔(206)中的切割门(204),使得切割门(204)可以在阀开口(206)中的“打开”位置和 “封闭”的位置。 切割门(204)的往复运动导致通过闸阀组件(100)的输送管道的切割操作。 闸阀组件(100)还包括沿着阀腔(206)旁边形成在阀块(102)中的塞槽(202)。 排渣坑(202)限定了一个开口,该开口可以包含来自切割操作产生的管道输送的弹簧的一个或多个切屑。 切割门(204)的往复运动将所输送的管道的一个或多个切屑输送到塞槽(202)。
