Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Embodiment of the present invention is such as Fig. 1, and feed chute 1 adopts carbon steel plate (Q235-A) welding system, and chute angle is 45 °. The rotary valve housing 2 and the spool 3 are made of wear-resistant 45# steel. The ribs 3-4 of the valve core 3 adopt two rectangular flat plates, the two long sides of the ribs 3-4 are respectively welded to the shaft 3-1 and the arc sealing surface 3-3, and the two short sides of the ribs 3-4 are connected to the end plate 3 -2 welding. The outer surface of the arc sealing surface 3-3 and the inner surface of the housing 2 are precision machined, and the control gap is about 0.8 mm. The angle between ribs 3-4 is 150°. The upper arc angle of the rotary valve housing 2 is 45°, and the lower arc angle is 150°. The driving mechanism 5 adopts a pneumatic actuator. The solid material in this embodi...

Abstract

The solid materials rotary valve involves in a rotary valve which is used for control solid material flow circulating or not. The valve consists of valve body and drive executive device, the valve body consists of valve shell (2) and spool (3); the spool (3) is installed on the central axle of valve shell (2), the upper of the valve shell (2) is equipped with feeding mouth (2-1) which is connected with the feeding chute (1), the lower of the valve shell (2) is equipped with discharging mouth (2-2) which is connected with discharging chute (4); the drive executive device (5) is linked with the revolution axis of spool (3) through linking bar (6). The rotary valve in the invention has not hear phenomenon during the closing process, the abrasion is slight, it is helpful for maintaining the stability of rotary valve air impermeability, namely the air impermeability is not reduced with the prolong of valve using time. The rotary valve has not hear phenomenon during the total process, the drive motor need not overcome shearing force, the power loss is small; the abrasion is slight in the rotary valve working process, the use life is long; the sealed surface need not expensive wear-resisting process, the cost of the rotary valve is low.

Description

technical field [0001] The invention relates to a rotary valve used for controlling the flow and cut-off of solid materials, which belongs to the technical field of valve manufacturing. Background technique [0002] At present, the commonly used rotary valves mainly include ball valve and spherical valve. The ball valve is mainly composed of a shaft with a material flow channel sealed in a cast iron or steel shell. Under the action of the shaft, the shaft is rotated within a certain angle to realize the on-off control of the material flow. The spherical valve is mainly composed of cast iron or steel shell, valve core and driving mechanism. The valve core is composed of a spherical sealing surface, a shaft and a reinforcing rib connecting the shaft and the spherical sealing surface. The valve core rotates within a certain angle under the action of the driving mechanism to realize the on-off control of the material flow. These two types of valves are easy to be stuck by the ...
