And the V-shaped valve plate groove is correspondingly provided with a sealing structure.
The sealing structure is made of sealing strips or flexible scraper materials and is fixed on the valve body through the pressing strips.
The driving device is a hydraulic oil cylinder or an air cylinder or an electric pushing cylinder.
Adopt above-mentioned technical scheme's beneficial effect: the directional conveying switching valve is provided with a valve body, the valve body is a three-way valve body and is provided with a material inlet, a first discharge port and a second discharge port, a valve plate which is integrally V-shaped is arranged between the material inlet and the first and second discharge ports, the V-shaped valve plate is of a rigid connection structure, penetrates through the valve body, and is driven by a driving device to horizontally reciprocate, so that the V-shaped valve plate has two working positions of connection and disconnection on the valve body. And the first valve plate and the second valve plate of the V-shaped valve plate are respectively provided with a conduction notch and a conduction stopping part, and the conduction notch of the first valve plate and the conduction notch of the second valve plate are staggered at a working position. That is, when the position of the conduction notch of the first valve plate corresponds to the first discharge hole, the stop part of the second valve plate is positioned at the position for blocking the second discharge hole, and the material inlet is conducted with the first discharge hole; when the second discharge port is required to be communicated, the driving device drives the V-shaped valve plate to horizontally move, the through stopping part of the first valve plate corresponds to the first discharge port, the material at the first discharge port is blocked, meanwhile, the communicating notch of the second valve plate is located at the corresponding position of the second discharge port, the material inlet is communicated with the first discharge port, and the switching and conveying of the material are achieved.
The V-shaped valve plate is of an integral rigid connection structure, and is even in stress and not easy to deform. The V-shaped valve plate reciprocates along the V-shaped valve plate groove of the valve body to form the positioning effect similar to a V-shaped guide rail, and the positioning is accurate and the sliding resistance is small.
The first valve plate and the second valve plate are in an inclined state, pressure applied to the valve plate on the closing side is only component force of gravity, pressure on the valve plate is relatively small, the valve plate is not prone to deformation, the sealing effect is good, resistance of the valve plate to opening and closing is small, opening and closing are convenient and rapid, the power model of the valve plate driving device can be reduced, and cost is reduced. Because the bearing pressure of the material to the valve plate is reduced, the material has a scouring effect on the valve plate in the falling process, and the material is not easy to bond at the valve plate, so that the blockage of a channel is caused. When the V-shaped valve plate reciprocates at two working positions, the V-shaped valve plate groove can scrape materials adhered on the valve plate, and the blocking occurrence is reduced.
This directional conveying switching valve is three channel structure forms, and the cooperation blanking pipe uses, and when blocking phenomenon appears in the long-time operation of one side blanking pipe, traditional flap valve structure turns over the board because of the material hinders, and the flap valve can't switch, and another reserve blanking pipe unloading can't be realized, can only wait to clear up just can normally the unloading after dredging the blanking pipe that blocks up or switch, and this directional conveying switching valve still can fast switch to another reserve blanking pipe unloading under the condition that one side blockked up to guarantee the normal unloading of whole conveying system.
