Abstract
The utility model discloses a filtering three-way control valve, comprising a valve body. A valve cover is connected on the valve body; inside the valve body, a valve disc is connected with a valve shaft; the upper end of the valve shaft is connected with a valve disc motion control device; the valve body is provided with three flow passage openings; a flow passage partition board is arranged on the valve body; a flow passage hole is arranged on the flow passage partition board; the flow passage hole is connected with an upper valve seat; a flow passage opening on the valve body is connected with a lower valve seat; the valve disc is arranged between the upper end the lower valve seats. The valve disc motion control device of the utility model can be a diaphragm control device. The utility model is applied to the filtering control and the backwashing of filter devices in a water supply pipe network. The original four control valves are reduced to two control valves so as to save costs of the project, meanwhile, the control and operation is easy and simple.
Description
Technical field
The utility model belongs to control valve for fluids, is specifically related to a kind of three-way control valve of controlling filtering flow and recoiling device.
Background technique
The control of filtrating equipment is to realize filtering and recoiling by four butterfly valves that connect in the pipeline in the water supply network at present, as shown in Figure 1.When valve 2,3 cuts out, valve 1,4 is opened, and realizes normal filtration; When valve 1,4 cuts out, valve 2,3 is opened, and carries out backwash.This control mode, ducted valve is many, construction cost height, control operation complexity.
Summary of the invention
The purpose of this utility model is to design a kind of three-way control valve, to overcome the defective that above-mentioned filtrating equipment control exists.
The technological scheme that the utility model filters three-way control valve is: valve body, the valve gap that connects on the valve body, valve disc in the valve body is connected with valve shaft, the valve shaft upper end connects the valve disc motion control device, and three runner mouths are arranged on the valve body, is provided with the runner dividing plate in the valve body, open the runner hole on the runner dividing plate, going up of runner hole connects upper valve base, connects lower valve base on the runner mouth on the valve body, and valve disc is located between the lower valve base.
The valve disc motion control device of this valve can be the barrier film control gear.This valve is used for the filtration control and the backwash of water supply network filtrating equipment, and original four control valves are reduced to two control valves, saves engineering cost, and control operation is convenient and simple.

Embodiment
As shown in Figure 2, valve body is connected and composed by upper valve body 9 and following valve body 14, and upper valve body 9 connects bottom flange 8, bottom flange 8 connects bonnet 5, the cavity that connects between the last bottom flange is a diaphragm cavity 21, in the diaphragm cavity 21 septum assembly is arranged, and septum assembly comprises the diaphragm 7 between pressing plate 6, the pressing plate.Septum assembly connects valve shaft 10 and penetrates in the upper valve body.Upper valve body 9 is provided with two runner mouths 15,16, establishes another runner mouth 18 on the following valve body 14, and lower valve base 13 is located on this runner mouth 18.Runner dividing plate 17 is located in the upper valve body 9, and two runner mouths are separated; Open runner hole 19 on the runner dividing plate 17, the connection upper valve base 11 in runner hole 19, the valve disc 12 that valve shaft 10 lower ends connect is located between the lower valve base 11,14.Each film chamber connects solenoid directional control valve 20 up and down.
Adopt the pipeline that filters three-way control valve controlled filter device to connect as shown in Figure 3, it only needs two three-way control valves just can realize the control to filtrating equipment that former useful four butterfly valves just can be finished.
Working principle is: as a and the b of solenoid directional control valve 20, after c and the conducting of d difference, pressure medium (water or air) enters the diaphragm cavity epicoele through a, b, the pressure medium of cavity of resorption is discharged through c, d, and diaphragm moves downward, and it is downward to promote valve disc 12 by axle, close runner mouth 18,15,16 conductings of runner mouth.
As a and the c of solenoid directional control valve 20, after b and the conducting of d difference, pressure medium (water or air) enters the diaphragm cavity cavity of resorption through a, c, the pressure medium of epicoele is discharged through b, d, and diaphragm moves upward, and promotes valve disc 12 upwards by axle, close runner mouth 16,15,18 conductings of runner mouth.
