Problems solved by technology

For the Taylor ball valve, because the valve body is spherical, it can rotate freely in the valve cavity, and its sealing surface is uncertain. The surface of the valve body is quickly worn out under the scouring of the slurry, resulting in lax closure. The general life expectancy is 2-3 month
For manual, pneumatic, and electric gate valves, due to their complex structure, high cost, and manpower or other power operations, the above two types of valves are currently used in mineral processing plants, each with its own advantages and disadvantages.

Embodiment Construction

[0012] The assembly relationship of the above-mentioned Naipurin overturn valve is the embodiment of the present invention, and its production and assembly relationship is: one end of the swing arm rotary shaft 7 is fixed on the valve housing 1, the swing arm 6 is sleeved on the swing arm rotary shaft 7, and the swing arm rotary shaft 7 The other end is provided with a valve 4 rotary shaft, the valve 4 is sleeved on the rotary shaft, the upper end of the valve 4 is symmetrically offset by two guide wheels 3 on both sides, the guide rail 2 and the turning wheel 5 are connected to the cover plate 8, and the cover plate 8 passes through The connecting bolt 9 is integrally connected with the valve casing 1 . All surfaces in contact with the slurry are covered with wear-resistant materials.

Abstract

The invention relates to an automatic two-position three-way overturning valve used in liquid or ore pulp conveying pipes, namely the Naipu lin-jun overturning valve. The Naipu lin-jun overturning valve is characterized in that when pulp enters one pipeline and the other pipeline needs to be closed, the valve (4) swings to the other side automatically under the pushing of ore pulp pressure, and then one ore pulp pipeline is closed. To solve the problems that as a large amount of granular ore is contained in the ore pulp, the valve (4) is abraded seriously and the service life is short, the valve (4) is restrained by a swing arm (6), a guide rail (2), a guide wheel (3) and an overturning wheel (5), the valve (4) can achieve revolution and auto-rotation, the working face (a closed face) is back on to flushing of ore pulp in the unclosed pipeline all the time, the working face is protected against abrasion, and the service life of the valve is prolonged greatly.

Description

technical field [0001] The invention relates to an automatic opening or closing valve for the pipeline of the slurry pump (one for standby and one for use) used in ore dressing plant. Background technique [0002] There are several types of opening and closing valves for the slurry pump (one for standby and one for use) in the current dressing plant: 1-Taylor ball valve (automatic opening and closing), 2-manual, pneumatic and electric gate valves. For the Taylor ball valve, because the valve body is spherical, it can rotate freely in the valve cavity, and its sealing surface is uncertain. The surface of the valve body is quickly worn out under the scouring of the slurry, resulting in lax closure. The general life expectancy is 2-3 months. For manual, pneumatic and electric gate valves, due to their complex structure and high cost, manpower or other power is required to operate, so the above two valves are currently used in mineral processing plants, each with its own advant...
