Background

The valve that traditional material was carried and was used when switching adopts the structure of turning over the board more, and this kind of valve is applicable to light material more, and long-time the use is because of turning over board bonding material more and more, turns over the board and can appear the card phenomenon of dying when switching, and the upset is switched not in place, seals not tight, takes place easily and leaks the circumstances such as material. The invention discloses a novel hydraulic split gate valve, which is widely applied in material conveying, such as publication No. CN 104132150A of publication No. 2014.11.05, and is characterized in that the gate valve is composed of a valve body and a gate plate clamped in a horizontal chute on the inner side wall of the valve body, and the gate plate is connected with a reciprocating power mechanism, wherein: the two insertion plates are oppositely arranged and are positioned on an upper plane and a lower plane, and the two insertion plates are provided with an upper overlapping part and a lower overlapping part when the valve is closed; the valve body is provided with an upper surface sealing structure and a lower surface sealing structure which seal the upper surface and the lower surface of the insertion plate, and a side sealing structure which seals the horizontal sliding groove and the side surface of the insertion plate is arranged in the horizontal sliding groove in which the insertion plate is clamped. Compared with the prior art, the valve has the advantages of low power consumption and no leakage, solves the problems of easy blockage and blockage of the conventional valve in the current market, and can be used as a valve for powder materials. The gate valve structure bears the weight of materials on the upper portion, the valve plate is large in opening and closing resistance, the required driving force is correspondingly large, and the requirement on correspondingly selected power execution elements is high. Meanwhile, materials with high pressure are easily extruded and bonded in the track of the valve plate, and the valve plate is blocked to open and close, so that the situation of untight plugging is caused.

Disclosure of Invention

In order to solve the problems in the prior art, the invention aims to provide the directional conveying switching valve which is reliable in material flow direction switching, smooth in opening and closing, not easy to block and good in sealing effect.

In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a directional conveying switching valve, has the valve body, the valve body has material inlet, first discharge gate and second discharge gate, its characterized in that: the valve body is internally provided with a V-shaped valve plate, two side walls of the valve body are provided with V-shaped valve plate grooves through which the V-shaped valve plates extend, and the V-shaped valve plates can reciprocate along the V-shaped valve plate grooves to form switching of two working positions of stopping the second discharge port when the first discharge port is stopped and switching the second discharge port or stopping the first discharge port; the valve body is fixedly connected with a support, a driving device is fixed on the support, and the driving device is connected with the V-shaped valve plate and drives the V-shaped valve plate to reciprocate.

The V-shaped valve plate is provided with a first valve plate and a second valve plate, the first valve plate and the second valve plate are fixedly connected at one side of the bottom of the first valve plate and the second valve plate to form a V-shaped structure, two sides of the V-shaped structure are respectively provided with a connecting plate, and the connecting plates are fixedly connected with the first valve plate and the second valve plate; the first valve plate and the second valve plate are respectively provided with a conduction notch and a stop part, and the conduction notch of the first valve plate and the conduction notch of the second valve plate are staggered to form a working position.

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.
