Abstract

The invention provides a novel safety valve pipeline of an offshore oil platform. The novel safety valve pipeline comprises an inlet and an outlet, wherein a main channel is arranged between the inlet and the outlet, and a first ball valve, a safety valve and a second ball valve, sequentially connected in series through pipelines, are arranged on the main channel; an auxiliary branch channel is further arranged between the inlet and the outlet, and a valve group is arranged on the auxiliary branch channel; and the valve group comprises a first valve body and a second valve body connected in series, the first valve body is a stop valve, and the second valve body is a ball valve. By adopting the technical scheme, pipeline disconnection caused by the trouble shooting of the safety valve on a platform pressure pipeline is compensated, the flexibility of the pipeline is improved, and the production efficiency is high; and as only one auxiliary branch channel is increased, less fees are spent on connecting temporary channels than an original pipeline disconnection state, and the cost is low.

Description

technical field [0001] The invention belongs to the field of safety equipment for oil pipeline transportation, in particular to a new safety valve pipeline for offshore oil platforms. Background technique [0002] In the process of offshore oil production, in order to ensure safe production and prevent explosion accidents due to various accidents that cause the pressure of the production system to exceed the design pressure of the container and pipeline, a safety relief valve should be installed on the container and pipeline of the production system. Known as the safety valve. In the prior art, the safety valve is connected in series on the oil transportation pipeline. When the safety valve needs to be overhauled, the entire transportation pipeline must stop working, which takes a long time for maintenance and low work efficiency. Contents of the invention [0003] In view of this, the present invention aims to propose a new type of safety valve pipeline for offshore oil ...
