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 variable-diameter valve for high-precision resistance-increasing and pressure-regulating control, which includes a support tube and a rubber tube built in the support tube. An adjustment device for adjusting the cross-sectional size of the rubber tube is installed on the support tube. The end of the support tube is fixed There is a flange plate, and the driving device for driving the adjustment device is fixed on the support tube. The driving device pushes the sliding sleeve to slide along the axial direction of the support tube. The transformation of the pipeline in the structure of the present invention should be adapted to the original mining system as much as possible. And it retains the convenient reducibility and improves the test efficiency. The present invention is a nestable flange structure, and all structures can be nested in the original pipeline system, with high convenience, low difficulty in disassembly and installation, and no need for on-site welding , a production system suitable for sea trials. This device can be installed in low water and deep sea test to adjust the pressure, and this device can be removed in high water depth production.

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...
