摘要： Wellhead flow control valve including a valve body, a hydraulic linear actuator means connected to valve body in alignment with operating chamber. Actuator has Belleville spring return. A seat sleeve carrying a valve seat and an internal lining mounts at outlet of operating chamber. Drive shaft moves flow control member of prescribed configuration into and out of valve seat sleeve. Flow control member and valve seat cause complete flow closure. Hydraulic conduit connects into actuator to admit hydraulic fluid to move piston and to compress spring. Activator is responsive to a pilot signal for: activating a pump control switch; to permit operation of pumps; activating a by-pass valve switch to keep closed a by-pass valve between conduit and sump of pump; and activating a blocking valve switch to keep open a blocking valve connected between pump and actuator. Flow throttling valve connected into conduit between actuator and other valve control apparatus to adjustably control rate of travel of piston by adjusting flow rate. Pressure sensing means connects into product pipe downstream from control valve and connected: to switch by-pass valve switch to open hydraulic by-pass valve and to switch pump control switch to closed position to stop pump and to close control valve when prescribed to high product pressure occurs; and to switch pump control switch to start pump and to switch by-pass valve to close hydraulic pass valve to stop and to open control valve when a prescribed lower product pressure occurs.
摘要翻译：井口流量控制阀包括阀体，与操作室对准的阀体连接的液压线性致动器装置。执行机构有Belleville春季回归。承载阀座和内衬的座套可安装在操作室的出口处。驱动轴将规定构造的流量控制构件移入和排出阀座套筒。流量控制构件和阀座导致完全的流动关闭。液压管道连接到执行器中，以允许液压流体移动活塞并压缩弹簧。激活器响应于一个导频信号：激活泵控制开关; 允许泵的运行; 激活旁路阀开关以在泵的管道和集油槽之间保持关闭旁通阀; 并启动阻塞阀开关，以保持打开连接在泵和执行器之间的阻塞阀。流量节流阀连接到执行器和其他阀门控制装置之间的导管中，通过调节流量来调节活塞行程的速度。压力传感装置连接到控制阀下游的产品管道并连接：切换旁路阀开关打开液压旁通阀，并将泵控制开关切换到关闭位置，停止泵并关闭控制阀压力发生; 并且当规定的较低产品压力发生时，切换泵控制开关以启动泵并切换旁通阀以关闭液压通过阀停止并打开控制阀。

摘要： A new wellhead housing structure which utilizes identical units of a unique wellhead housing of selected internal diameter and pressure rating. Each wellhead housing utilizes a new flexible bowl ("flexbowl") hanger support ring which may be installed and removed as desired during assembly of the wellhead structure during completion of the well. Each wellhead housing forms an internal circumferential groove to receive the flexible bowl hanger support ring in position to receive and support different kinds and sizes of hangers for casing, protective sleeves, and the like. The flexible bowl support ring is drawn into a contracted position. The contracted support ring will pass through the wellhead housing and is seated by a setting tool. Subsequently, a tubing or casing hanger may be landed upon the support ring and supported by the support ring which serves the same functions as the bowl seat in a conventional wellhead housing. The support ring may be removed by a removal tool.
摘要翻译：一种新的井口外壳结构，其采用相同的单元，其具有选定的内径和压力等级的独特的井口壳体。每个井口壳体都使用一个新的柔性碗（“弯头”）衣架支撑环，可在井的完井期间组装井口结构期间根据需要安装和拆卸。每个井口壳体形成内部周向凹槽，以将柔性碗挂架支撑环接纳在适当位置，以容纳和支撑用于套管，保护套等的不同种类和尺寸的衣架。柔性碗支撑环被拉入收缩位置。承包的支撑环将穿过井口外壳，并由安装工具安置。随后，管道或套管悬挂器可以落在支撑环上并由支撑环支撑，支撑环在常规的井口壳体中起到与碗座相同的作用。支撑环可以通过去除工具去除。

摘要： A valve is disclosed that is operable by converting rotational force of a stem into linear motion of a valve closure element, such as a sleeve, to control fluid flow through the valve. In a presently preferred embodiment, at least two interconnection members are rotatably mounted, such as with a round end, to a stem drive element. The interconnection members are slidably mounted into channels or grooves in a sleeve. Rotatable movement of the stem permits rotation of the interconnection members whereby the interconnection members are constrained to slide in the channels whereby rotational movement of the stem is converted into translational or linear movement of the valve closure element.
摘要翻译：公开了一种阀，其可通过将阀杆的旋转力转换成阀闭合元件（例如套筒）的线性运动来操作，以控制通过该阀的流体流动。在目前优选的实施例中，至少两个互连构件可旋转地安装，例如具有圆形端，到杆驱动元件。互连构件可滑动地安装在套筒中的通道或槽中。杆的可旋转运动允许互连构件的旋转，由此互连构件被限制为在通道中滑动，由此杆的旋转运动转换成阀闭合元件的平移或线性移动。

摘要： A high pressure seal structure to seal against fluid pressure around a cylinder member movably. The structure includes an integral circular metal sealing ring including a pair of first circular sealing lips having a cross-section of chevron shape axially opening in a first direction to flexibly extend with a first inner lip in sealing relation against the cylindrical surface of the cylinder member and with the first outer lip in sealing relation against a cylindrical wall formed in the housing. Also included is a pair of second circular sealing lips having a cross-section of chevron shape axially opening in a second direction to flexibly extend with a second inner lip in sealing relation against the cylindrical surface and with a second outer lip in sealing relation against the cylindrical wall. A deformable inner sealing ring having a triangular cross-section is closely fitted in the space defined by the first inner lip, the second inner lip, and the cylindrical surface. A deformable outer sealing ring having a triangular cross-section is closely fitted in the space defined by the first outer lip, the second outer lip, and the cylindrical wall. A first circular and moveable and metal engagement ring having a cross-section of chevron shape axially extends into the opening form by the first sealing lips to expand the first sealing lips. A second circular and moveable metal engagement ring having a cross-section of chevron shape axially extends the opening formed by the second sealing lips to expand the second sealing lips. An axially moveable circular adjustment structure is provided to urge the first engagement ring and the second ring together for expanding the first sealing lips and the second sealing lips.
