Problems solved by technology

Widely used in chemical industry, environmental protection, petroleum, metallurgy, refractory materials, electric power, cement, plastics, food and medicine and other industries. During the use of rotary valves, in order to increase production and ensure quality at the same time, the material at the feed port is equipped with high temperature and high pressure , to speed up the maturation of the material, but the high temperature and high pressure inside the rotary valve will reduce the sealing performance inside the rotary valve, and may even damage the components of the rotary valve. Therefore, how to solve the above technical problems has become a research direction for people in the technical field

Abstract

A gas balance high-pressure rotary valve comprises a shell, a motor, a rotor and end covers, the end covers are fixed to the left end and the right end of the shell, bearings are arranged on the end covers, the rotor is rotationally connected into an inner cavity of the shell through the bearings, the motor is rotationally connected with the rotor through a speed reducer, and each end cover is provided with a bearing containing cavity, a cooling air cavity, a sealing cavity and a rotor containing cavity. The inner wall of the cooling air cavity is provided with an air inlet and an air outlet which are communicated with the outer wall of the end cover, the inner wall of the bearing containing cavity is provided with an oil injection hole communicated with the outer wall of the end cover, and the inner wall of the rotor containing cavity is provided with an air inlet communicated with the outer wall of the end cover. High-pressure air can be input through the air inlet to balance the high pressure of the feeding port, materials in the rotor are prevented from entering the outer side of the rotor and a bearing area under the high-pressure condition, cold air can be input through the air inlet and the air outlet to cool the bearing, a lubricating agent can be more conveniently injected into the bearing through the oil injection port, and the service life of the bearing is prolonged. The service life of the rotary valve is prolonged.

Description

Technical field [0001] The present invention relates to the field of rotary valves, in particular a gas balancing high-pressure rotary valve. Background [0002] Rotary valve is used in powder (powder foam, granular materials, powder mixture) conveyor system for unloading, metering, dust removal, quantitative conveying, mixing, packaging of special equipment. Widely used in chemical, environmental protection, petroleum, metallurgy, refractory materials, electricity, cement, plastics, grain and medicine and other industries, in the use of rotary valves, in order to increase the output while ensuring quality, the inlet end of the material with high temperature and high pressure, in order to accelerate the speed of material curing, but the high temperature and pressure inside the rotary valve will make the sealing performance inside the rotary valve reduced, and may even damage the rotating valve components, therefore, how to solve the above technical problems has become the directi...
