Problems solved by technology

Due to the mass concentration of ore particles, general gate valves and ball valves cannot work under this condition
Although the pinch valve can operate in the slurry working condition, its internal rubber hose is prone to fatigue, and it is difficult to adjust the pump working condition point close to the optimal working condition point

Abstract

The invention discloses a high-precision resistance-increasing pressure-adjusting control variable-diameter valve. The high-precision resistance-increasing pressure-adjusting control variable-diameter valve comprises a supporting pipe and a rubber pipe arranged in the supporting pipe, wherein the rubber pipe used for adjusting the size of a cross section of the rubber pipe is installed on the supporting pipe, a flange plate is fixed to an end portion of the supporting pipe, a driving device used for driving an adjusting device to move is fixed onto the supporting pipe, and the driving device pushes a sliding sleeve to slide in an axial direction of the supporting pipe. According to the structure of the high-precision resistance-increasing pressure-adjusting control variable-diameter valve, reconstruction of a pipeline needs to adapt to an original mining system as much as possible, the convenient recoverability is kept, the trial efficiency is improved, the high-precision resistance-increasing pressure-adjusting control variable-diameter valve is of a flange structure which can be embedded, all structures can be embedded into the original pipeline system, thus convenience is high, the difficulty degrees of detachment and additional installation are low, field welding is not needed, and the high-precision resistance-increasing pressure-adjusting control variable-diameter valve is suitable for a production system of sea trial ships; and the device (high-precision resistance-increasing pressure-adjusting control variable-diameter valve) can be additionally installed in sea trials at low water depths to adjust the pressure, and the device (high-precision resistance-increasing pressure-adjusting control variable-diameter valve) can be removed in production at high water depths.

Description

technical field [0001] The invention relates to the field of valves, in particular to a variable-diameter valve for high-precision resistance-increasing and pressure-regulating control. Background technique [0002] The pinch valve is a flow regulating device that can adjust the resistance of pipeline transportation. In the pump slurry test system of the current mining transportation test system, the transported slurry is mixed with seawater and ore particles with a diameter of 3-30mm. The mass concentration is between 3-15%. In the low-water deep-sea test mining transportation system, the slurry lift pump adopts deep-sea design parameters. In the 50m water deep-sea test, the pump outlet head may be 90-270m, far exceeding the demand for hydraulic transportation, so it is necessary to increase the transportation resistance in the pipeline and adjust The head flow rate of the pump makes it work in a reasonable power range. Due to the mass concentration of ore particles, gene...
