An outdoor valve for oil pipeline with antifreeze function

Abstract

The invention relates to the technical field of valves, in particular to an outdoor valve for petroleum pipelines with antifreeze function, comprising a valve body, a heat preservation mechanism is installed on the valve body, and a plurality of locking mechanisms are connected to the heat preservation mechanism, A support mechanism is installed on the heat preservation mechanism, a control mechanism is connected to the support mechanism, and a discharge mechanism is installed on the heat preservation mechanism; under the action of the locking mechanism, the disassembly and assembly of the heat preservation mechanism and the valve body is convenient, and the heat preservation mechanism has It is beneficial to convert solar energy into electric energy and generate heat to heat and keep the outside of the valve body, which is beneficial to prevent the valve body from being damaged by freezing in winter. It is convenient to drive and control the support mechanism under the action of the control mechanism. It is convenient for storage and storage, and it is convenient to discharge the water vapor and pressure generated between the heat preservation mechanism and the valve body under the action of the discharge mechanism, which reduces the damage to the valve body and the heat preservation mechanism and prolongs the service life.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an outdoor valve for petroleum pipelines with antifreeze function. Background technique [0002] Oil needs to be transported remotely through pipelines during transportation, and in order to facilitate the on-off control of transportation, valves are installed on the pipeline, so as to facilitate the control of the opening and closing of oil pipelines, which is conducive to subsequent maintenance and installation of pipes. [0003] In the severe cold winter, the exposed oil pipeline valve will be frozen with air-conditioning, which is inconvenient for the staff to rotate during use, and it is easy to cause the valve to rupture and damage in severe cases. Traditionally, the valve is wrapped with thermal insulation cotton when antifreeze is installed. At the same time, it is inconvenient to operate, time-consuming and labor-intensive. At the same time, the effect of wrapping insulat...

Problems solved by technology

[0003] In the severe cold winter, the exposed oil pipeline valves will be frozen by the cold air, which is inconvenient for the staff to rotate during use, and in severe cases, the valves may be easily broken and damaged. Traditionally, when antifreezing, the valves are wrapped with thermal insulation cotton. It is inconvenient to operate, time-consuming and labor-intensive. At the same time, the effect of simply wrapping the insulation cotton is poor. When the temperature is low, the valve will still be cracked and damaged, which will cause oil spillage inside the pipeline and cause harm.
