Abstract

The invention relates to the technical field of oil-gas field construction operation equipment, in particular to an anti-sand-accumulation plug valve which comprises a valve body, a valve cover and aplug rod arranged in the valve body. The valve body is connected with the valve cover; the lower end part of the plug rod is connected with a plug; a driver is arranged on the upper end part of the valve body and is connected with the valve body; the driver transmits a torque to the plug rod through a flat key; a sealing rubber core is arranged on the outer part of the plug; a piston is arranged on the upper part of the sealing rubber core; an annular seal cavity is formed among the plug, the plug rod and the piston; a spring is arranged in the seal cavity; the piston, the plug rod, the sealing rubber core and the plug are located in an inner core of the valve body; the inner core of the valve body communicates with an oil passage; and the oil passage is filled with hydraulic oil for driving the piston to move up and down. According to the anti-sand-accumulation plug valve provided by the invention, a gap between the sealing rubber core and the plug can be adjusted, and no gap exists among the plug, the sealing rubber core and the valve body during a pressure-bearing and fluid conveying process, so that sand is prevented from being accumulated.

Description

technical field [0001] The invention relates to the technical field of oil and gas field construction equipment, in particular to an anti-sand accumulation plug valve. Background technique [0002] The structure and principle of the existing cock valve are: the sealing parts of the existing cock valve are mainly metal valve body, metal cock, metal sealing arc and non-metallic seal, the inner side of the cock and sealing arc and the valve body and The outside of the sealing arc needs to be sealed. The valve body, cock and sealing arc are all designed with flow channel holes of the same size. When the axes of the flow channel holes of the three are collinear, the cock valve is in the open state. When the cock rotates 90 degrees around its axis, the flow channel of the cock The hole, the arc and the flow channel hole of the valve body are in a vertical state, and the plug valve is closed. [0003] The shortcomings and deficiencies of the existing cock valve mainly include the...
