Description

Distributing valve suitable for high-pressure conveying working condition and filling industrial pump Technical Field The invention belongs to the field of mining machinery and engineering machinery, and particularly relates to a distributing valve and a filling industrial pump suitable for high-pressure conveying working conditions. Background With the rise of engineering machinery, the filling industrial pumps include an S-valve industrial pump, a skirt-valve industrial pump, a cone-valve industrial pump, and the like. The requirement for diversification of the application field of engineering machinery products; different pumps have their own advantages and disadvantages. The S valve pump is suitable for conveying thick bone slurry, and has the defects of incapability of high-pressure conveying, and the common cone valve pump can be used for high-pressure conveying, but quick wear of vulnerable parts (such as cone valves, valve groups and the like) and short service life when working for a long time under high pressure. In the mine field, the reason why the pipeline is high-pressure is generally that slurry is pumped from bottom to top, the pumping distance is far, the pumping vertical distance is large, and the like. The existing cone valve type distribution valve is characterized in that two groups of mutually perpendicular cone valve cylinders are respectively arranged on a suction valve shell and a pressure valve shell to serve as power parts, wherein the suction valve cylinders are vertical conveying cylinders, the pressure valve cylinders are horizontal conveying cylinders, the distribution valve is greatly influenced by water hammer effect due to the fact that conveying pressure in a high-pressure conveying pipe is large, and the back-flowing high-pressure slurry directly impacts contact surfaces of the pressure cone valve and the pressure valve cylinders with different forces, so that eccentricity is easily caused, concentricity of the cone valve and a pressure valve seat is influenced, the high-pressure slurry cannot be well sealed, jet flow is generated, a vulnerable part is directly damaged, and in addition, abrasion of piston rods of the pressure cone valve and the pressure valve cylinders is easily caused under the gravity of the pressure cone valve and the pressure cone valve, sagging is easily caused, and coaxiality of cooperation of the cone valve and the valve seat is influenced.
