Embodiment Construction

[0011] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] Such as figure 1 and figure 2 As shown, the meterable star valve includes a discharge valve housing (1), a feed pipe (2) located at the upper part of the housing (1), a discharge pipe (3) located at the lower part of the housing (1) and The impeller (4) located in the housing and the rotating shaft (5) driving the impeller (4); the impeller (4) has six blades ( 41 ), and the blades ( 41 ) divide the impeller ( 4 ) into equal-sized The number of grids (42) equal to the number of blades (41); the size of the opening (43) of the (42) grid is equal to or greater than the size of the inlet of the discharge pipe (3); the axis of rotation (5) along the There are permanent magnets (9) with the same number as the blades (41) and corresponding positions evenly distributed on the circumference; a reed switch (8) matched with the permanent m...

Abstract

The invention discloses a gaugeable star-shaped valve which comprises a discharge valve shell, a feed pipe positioned at the upper part of the shell, a discharge pipe positioned at the lower part of the shell, an impeller positioned in the shell and a rotary shaft used for driving the impeller; at least three blades are arranged on the impeller; the blades separate the impeller into boxes with equal size and same quantity with the blades; the size of an opening of each box is equal to or larger than that of an inlet of the discharge pipe; permanent magnets which are uniformly distributed along the periphery of the rotary shaft has the same quantity with the blades and corresponds to the positions of the blades; and reed pipes matching with the permanent magnet are arranged at the side of the rotary shaft. The gaugeable star-shaped valve provided by the invention controls a stepping motor through a controller and counts through the reed pipes to figure out volume or weight of a material passing through the star-shaped valve. According to the gaugeable star-shaped valve, each box has equal size, so that measurement to a box can be realized precisely; the boxes can be increased or decreased, or the size of the boxes can be adjusted as required so as to realize different flows and measurement units; and therefore, the gaugeable star-shaped valve has stronger adaptability.

Description

technical field [0001] The invention relates to the technical field of unloading valves, in particular to a star unloading valve. Background technique [0002] The star unloading valve is a commonly used unloader device at present. Usually, the structure of the star unloading valve is composed of a rotor impeller with several blades, a shell, a seal, a reducer, and an electric motor. It can be used in the material collection system as the unloader of the silo. When the material in the upper silo falls by its own weight and fills the gap between the blades, it is discharged at the lower part with the rotation of the blades, and the material can be continuously discharged. out. However, the current star-shaped discharge valve is usually only used as a discharge device, which cannot measure the discharge volume, and cannot meet the need for effective control of the discharge volume. [0003] In order to solve the above-mentioned deficiencies in the prior art, the present inve...
