Abstract

The invention discloses a novel simple apparatus for simulating gate valve wearing. An upper cover plate is connected between the upper portions of a left pressing cover and a right pressing cover, and a lower cover plate is connected between the lower portions of the left pressing cover and the right pressing cover. The upper cover plate and the lower cover plate are provided with a replaceable simulation assembly, and organic glass plates are arranged on the two sides of the central portions of the upper and lower cover plates. The replaceable simulation assembly comprises a replaceable block, a screw and a block wearing sheet, wherein the replaceable block is installed in an upper groove in the bottom surface of the upper cover plate, the upper end of the replaceable block is connected with the screw passing through the upper cover plate, the installation height of the replaceable block can be adjusted by adjusting the screw so as to simulate the opening degree of a gate valve, and the block wearing sheet is pasted to the bottom of the replaceable block. Cost is saved substantially, the opening degree of the gate valve can be determined accurately, the structure is simple, dismounting is very convenient, and workload can be reduced substantially. Particle movement trace can be observed through the organic glass plate by using a high-speed photographic instrument, and the novel simple apparatus is widely applicable.

Description

technical field [0001] The invention relates to a gate valve, in particular to a novel simple device for simulating the wear of the gate valve. The opening of the gate valve is simulated by changing the height of the stopper, and the trajectory of the particles is observed through the transparent plexiglass plates on both sides. Background technique [0002] As an important component in industrial pneumatic conveying pipelines, gate valves will be seriously affected by gas-solid two-phase flow. The main function of the gate valve is to open and close the fluid medium passage, change direction, protect the safety of the system, and adjust the flow and pressure. It is one of the important control components of phase pipeline transportation system. During the opening and closing process, the cross section of the gate valve changes continuously, but the process of gas-solid two-phase flow is very complicated. Working in the gas-solid two-phase flow pipeline, the solid phase m...
