Problems solved by technology

[0003] However, the existing cut-off devices usually use the method of manual rotation and cut-off. Due to the large diameter of the oil and gas pipeline, the manual cut-off method will take a certain amount of time, and the oil and gas pipeline cannot be cut off in the first time, so it is easy to miss The truncation position of oil and gas pipelines, which in turn leads to greater economic losses

Abstract

The invention discloses a hydraulic cut-off device, which comprises an oil pump, a hydraulic cylinder, a mounting frame and a fixing frame, wherein the oil pump is fixed to the top of the horizontal end of the mounting frame through bolts; the outlet end of the oil pump is communicated with the inlet end of the hydraulic cylinder through an oil inlet pipe, and the inlet end of the oil pump is communicated with the outlet end of the hydraulic cylinder through an oil return pipe; a cut-off groove is formed in the fixing frame; a valve rod is connected to the lower portion of the hydraulic cylinder; and the bottom of the valve rod is connected with a gate plate penetrating through the cut-off groove through a connector. According to the hydraulic cut-off device, the valve rod and the gate plate can be integrally connected and fixed by the aid of the split type mounting structure and the valve rod connecting mode of the detachable structure, so that the driving force generated by the hydraulic cylinder is uniformly transmitted to the gate plate, the gate plate quickly and stably cuts off an oil-gas pipeline, the low efficiency caused by the traditional manual cut-off mode is avoided, and the operation flexibility of the cut-off device is further improved.

Description

technical field [0001] The invention relates to the technical field of oil and gas pipelines, in particular to a hydraulic cutting device. Background technique [0002] When oil and gas pipelines in oil and gas fields experience high oil and gas pipeline pressure, or pressure drops due to oil and gas pipeline blasting, or fires and other sudden dangers, in order to prevent further expansion of the danger and achieve the purpose of protecting well site equipment and personnel safety, It is necessary to quickly cut off the oil and gas pipeline. [0003] However, the existing cut-off devices usually use the method of manual rotation and cut-off. Due to the large diameter of the oil and gas pipeline, the manual cut-off method will take a certain amount of time, and the oil and gas pipeline cannot be cut off in the first time, so it is easy to miss The truncation position of oil and gas pipelines will lead to greater economic losses.
