Abstract
The utility model discloses an anti-plugging three-way valve with two valve plates, which is mainly composed of a valve body (1), a left valve plate (2), a right valve plate (3), a valve plate shaft (8), an upper connecting rod (4) and a lower connecting rod (5), wherein the two valve plates and the connecting rods form a plane four-rod linkage mechanism. When one of the two valve plate is driven, the two valve plates perform the same rotation action.
Description
Affiliated technical field
The utility model relates to a kind of three-way valve that is used for material diversion and has anti-plugging function.Can be adaptable across in industries such as building materials, chemical industry, metallurgy.Be applicable to the flow direction control of materials such as limestone, unslaked lime, gypsum, coal, coke, slag in course of conveying.
Background technique
Three-way valve is mainly used in the flow direction control to streams.Existing three-way valve all adopts the single valve plate around its bottom rotating shaft rotation flow direction of material to be switched; Because material directly washes away on the valve plate that tilts; The valve plate wearing and tearing are very fast; And when putty takes place in downstream,, be full of material in the valve body and stop valve plate and can't rotate that be the subject matter that exists in the three-way valve application process at these 2 always if need switch current direction.
Summary of the invention
The three-way valve that the utility model provided is realized the shunting to material through the four bar linkage that is installed in the valve body, has the function of anti-putty simultaneously.Shown in accompanying drawing 1, accompanying drawing 2; Left side valve plate (2) and right valve plate (3) symmetry are installed in the left and right sides of valve body (1); The center of rotation of valve plate is positioned on the intersection of inwall (6) and following inwall (7); The fixing connecting rod (4) of going up of its axle head of the valve shaft of two valve plates (8), identical two in the left and right sides go up connecting rod (4) and are connect by lower link (5) and constitute a plane four bar linkage, realize the interlock control of two valve plate open and closes.
The beneficial effect of the utility model is: left valve plate (2), right valve plate (3) can be in the interlock state of a control, and just three-way valve left and right sides arm has only a side can pass through material.When the left side arm is opened, both left valve plate (2) is opened, right valve plate (3) closure, and when the putty situation occurring; Through driving fourbar linkage, valve plate is closed on the left of realizing, the right side valve plate is opened; Material begins the arm entering downstream plant from the right side; Putty is owing to downstream plant consumption in the arm of left side, and putty begins to reduce, and finally solves the putty problem.Through the interlock of such valve plate, both solved three-way valve putty problem, realized to the uninterrupted feeding of downstream plant therefore having not putty, continue feeding, control advantages such as simple simultaneously.Valve body when work, suppose that left valve plate (2) opens, when right valve plate (3) is in vertical state; Certain material can be piled up in the Delta Region that star valve bottom straight section and right valve plate (3) constitute; During feeding, material is gone into the left side arm through this accumulation area, rather than directly slips into arm through valve plate; Thereby reduced the wearing and tearing of material to valve plate, the working life of having improved valve plate.The single-degree-of-freedom characteristic of equiarm fourbar linkage makes this interlock control be easy to realize that it is convenient, easy to maintenance to install, and safeguards simple, safe and reliable.

Embodiment
Accompanying drawing 1 to accompanying drawing 5 is one of embodiment of this model utility.In this scheme, the end connection oil hydraulic cylinder (9) at lower link (5) when hydraulic rod moves, drives lower link (5) motion, drives right valve plate (3), left valve plate (2) through valve shaft (8), and makes a valve plate be in the enable possition, and another valve plate is in the close position.When putty occurring, oil hydraulic cylinder switching-over motion realizes right valve plate (3), the exchange of left valve plate (2) opening state.During the oil hydraulic cylinder link motion, through last connecting rod (4) valve shaft (8) is produced moment, therefore, it is little that this embodiment has a closed required drive of unlatching, opens characteristics such as closed sensitivity.
Claims (1)
1. a bivalve plate that is used for material diversion resists stifled three-way valve; Four bar linkage through being installed in the valve body is realized the shunting to material; The function that has anti-putty simultaneously; It is characterized in that: left valve plate (2) and right valve plate (3) symmetry are installed in the left and right sides of valve body (1); The center of rotation of valve plate is positioned on the intersection of inwall (6) and following inwall (7), the fixing connecting rod (4) of going up of its axle head of the valve shaft of two valve plates (8), and identical two in the left and right sides go up connecting rod (4) and connect plane four bar linkage of formation by lower link (5).
