AI Technical Summary

Technical Problem

Existing sand removal devices are difficult to effectively remove small fine sand in natural gas, resulting in gas leakage problems.

Method used

A 210MPa sandproof flat valve is designed, and a sand removal assembly including a sand-swing sleeve, a sand-blocking sleeve, a spiral groove and a spiral blade are used. The spiral blades are pushed to rotate in the spiral groove by natural gas, increasing the vortex strength, thereby increasing the removal force of fine sand.

Benefits of technology

Effectively remove fine sand in natural gas, reduce gas leakage, improve sand removal efficiency, and clean rock blocks or coarse sand stuck in the spiral groove through the combination of magnets and impact slant blocks.

Abstract

The present invention belongs to the technical field of flat valves, and specifically relates to a 210MPa anti-sand flat valve, which includes valve one and valve two and a sand removal component installed between valve one and valve two; the sand removal component includes a sand removal pipe, a sand throwing sleeve, a sand retaining sleeve, a spiral groove, a spiral blade, a guide rod, a sand inlet cavity, and a sand removal cavity. When natural gas is introduced into the sand removal component, the spiral blade is pushed to the tail end of the spiral groove by the natural gas, and at this time, the sand particles with larger mass in the natural gas are thrown out through the head end of the spiral groove. When the natural gas passes through the tail of the spiral groove, the spiral blade crosses with the inner spiral blade at the tail of the sand throwing sleeve, and the eddy current intensity of the natural gas increases when passing through, and the inertial force of the natural gas on the fine sand also increases. Under the action of the inertial force, the fine sand is thrown out through the gap between the sand throwing sleeve and the sand retaining sleeve.
