Problems solved by technology

[0003] The distribution of oil production areas is uneven, and some pipelines lead from the north to the south. Due to the different geographical environment, and the characteristics of oil make the oil expand when it is transported to a place with a higher temperature, and it is easy to squeeze the ball of the ball valve to cause the ball to break. At the same time It will increase the internal pressure, which will increase the friction between the oil and the valve, increase the static electricity, and increase the risk factor, and the flow rate will affect the size of the static electricity

Abstract

The invention discloses a flexible self-adaption petroleum pipeline ball valve. The flexible self-adaption petroleum pipeline ball valve structurally comprises a valve body, a flexible ball, a seal ring, a shaft, a driver, a self-adjusting mechanism and a hand wheel. The flexible ball is arranged in the valve body. The seal ring is arranged between the flexible ball and the valve body. The top ofthe flexible ball is connected with the driver through the shaft. The side face of the driver is connected with the hand wheel. The self-adjusting mechanism is arranged above the driver and connectedwith the shaft. The flexible ball is composed of a ball shell, an elastic sheet, a connecting column, an ejection mechanism and a runner. The ball shell is arranged in the valve body and provided withthe penetrating runner, the connecting column is connected between the runner and the ball shell, the runner is provided with the elastic sheet, the part between the elastic sheet and the ball shellis a cavity, and the ejection mechanism is arranged in the cavity and fixedly connected with the ball shell. The flexible self-adaption petroleum pipeline ball valve has the beneficial effects that when petroleum is heated and expanded, the volume is enlarged for reducing extrusion damage to the ball, static electricity increasing under the heating situation is avoided, and safety is improved.

Description

technical field [0001] The invention relates to the field of petroleum transportation, in particular to a flexible self-adapting petroleum pipeline ball valve. Background technique [0002] Petroleum products are generally transported by pipelines, and ball valves are installed on the pipelines to control the flow and velocity of oil. [0003] The distribution of oil production areas is uneven, and some pipelines lead from the north to the south. Due to the different geographical environment, and the characteristics of oil make the oil expand when it is transported to a place with a higher temperature, and it is easy to squeeze the ball of the ball valve to cause the ball to break. At the same time It will increase the internal pressure, which will increase the friction between the oil and the valve, increase the static electricity, and increase the risk factor, and the flow rate will affect the size of the static electricity. Contents of the invention [0004] The main p...
