Abstract

The invention discloses a self-adaptive leakproof broadside valve which comprises a valve body, a support, a flow guide body, an axial flow valve rod, a valve clack, an electro-hydraulic actuator, a throttler, a valve disc, an outlet valve rod and a control box. The support is arranged at an inlet of the valve body, the flow guide body is connected with the valve body through the support, and thevalve clack is connected with the flow guide body through a spring seat, a spring, a gland, a seal ring and the axial flow valve rod. When large leakage happens to a pipeline, the valve can be automatically and rapidly closed.

Description

technical field [0001] The invention belongs to the field of side valves, in particular to an adaptive anti-leakage side valve. Background technique [0002] With the development of technology, large depth and large flow are the development trend of the current ship-to-sea system. As the voyage depth increases, the pressure on some pipelines is also increasing, and there are higher requirements for the safety and reliability of the pipeline. When the pressure increases to a certain level, there is a risk of accidental damage to the pipeline. At this time, it is necessary to cut off the fluid in the upper pipeline of the damaged pipeline urgently, and then repair the lower pipeline and equipment. Especially when the pipeline diameter is large, when the pipeline is damaged, if the side valve is not closed in time, the navigation safety of the ship will be affected. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, th...
