Directional conveying switch valve

Abstract

The invention discloses a directional conveying switch valve. The directional conveying switch valve is provided with a valve body, the valve body is provided with a material inlet, a first discharging port and a second discharging port, and the valve body is provided with a V-shaped valve plate; V-shaped plate grooves are formed in the two side walls of the valve body, the V-shaped valve plate penetrates through the V-shaped plate grooves and extends out of the V-shaped plate grooves, and the V-shaped valve plate can reciprocate along the V-shaped plate grooves, so that the first dischargingport is disconnected and the second discharging port is connected at the same time, or the first discharging port is connected and the second discharging port stops switch between the two work stations; and the valve body is fixedly connected with a support, a driving device is fixed to the support, and the V-shaped valve plate is connected to the driving device which drives the V-shaped valve plate to reciprocate. The directional conveying switch valve has the characteristics that the material flow direction is reliably switched, smooth opening and closing are achieved, flowing is not easilyblocked, and the closing effect is good. Normal discharging of an overall conveying system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a directional conveying switching valve. Background technique [0002] The valves used in the traditional material conveying switch mostly adopt the flap structure. This kind of valve is mostly suitable for light materials. When the flap is used for a long time, more and more materials are glued to the flap, and the flap will jam when switching. The dead phenomenon, the flip switch is not in place, the seal is not tight, and the material leakage is easy to occur. The gate valve is also widely used in material transportation. For example, the publication date is 2014.11.05 and the publication number is CN 104132150 A. The invention discloses a new type of hydraulic split gate valve. In the horizontal chute on the wall, the inserting plate is connected to the reciprocating power mechanism. It is characterized in that: there are two inserting plates, which are arranged o...

AI Technical Summary

Problems solved by technology

This kind of gate valve structure bears the weight of the upper material, the resistance of the valve plate opening and closing is relatively large, and the required driving force is correspondingly relatively large, and the correspondingly selected power actuators have relatively high requirements.

At the same time, the material with high pressure is easy to be squeezed and bonded to the track of the valve plate, jamming the opening and closing of the valve plate, resulting in a loose seal
