Embodiment Construction

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings. Wherein, the description in this specific embodiment uses descriptive terms such as up, down, left, right, etc., which are based on the orientation of the universal guide frame when it is in use.

[0053] Such as Figure 1 to Figure 4 As shown, the throttle valve is fed into the tool, including the guide cylinder 1, bracket and disassembly mechanism;

[0054] The guide cylinder 1 has a trumpet-like structure with a large top and a small bottom. There is a vertical notch on the side of the guide cylinder 1. The notch is used to enable the recyclable part 2 on the throttle valve and its rotary docking interface 21 to It is exposed from this gap; the upper edge of the guide cylinder 1 extends laterally outward to form a landing ring 11; the outer surface of the landing ring 11 is fixedly connected with a positioning block 12, and the lower end surface of the posi...

Abstract

The invention discloses a throttling valve feeding-in tool. The throttling valve feeding-in tool is characterized by comprising a guide barrel, a support and a disassembling mechanism, wherein the whole guide barrel has a trumpet-shaped structure; a vertical notch is formed in a side surface of the guide barrel; the edge of the upper end of the guide barrel transversely outwards extends to form a landing ring; the outer side surface of the landing ring is fixedly connected with a positioning block with a slot in the lower end; a hanging ring is fixedly mounted at the upper end of the support; the lower end of the support is fixedly connected to the upper surface of the landing ring; the middle of the support in the height direction is fixedly connected with a mounting plate; the disassembling mechanism is fixedly mounted on the mounting plate and comprises a hydraulic cylinder and an operating arm; a piston rod of a hydraulic rod faces downwards; and the lower end of the piston rod is fixedly connected with the operating arm. The throttling valve feeding-in tool has the advantages of skillful and reasonable structure, simplicity and convenience in use, and reliable and efficient disassembling operation, and is worthy of being popularized and used in the field.

Description

technical field [0001] The invention belongs to the field of installation tools for underwater Christmas trees, in particular to a throttle valve feeding tool for underwater Christmas trees. Background technique [0002] The underwater oil production system is a set of underwater oil and gas production and transportation system composed of an underwater completion system and production facilities installed on the seabed, manifold systems and submarine pipelines. The system transports oil and gas produced from the wellhead from the seabed to the recovery equipment or onshore terminal through the operation control of the surface and subsea control systems. [0003] The subsea oil production tree is the core component of the subsea oil production system. It mainly consists of connectors, the main body of the oil production tree (including various corresponding valve groups), pipelines and their joints, control modules and their corresponding connections, wellhead safety valves,...
