Abstract
The utility model relates to a water treatment apparatus with a one-way valve, comprising a water treatment apparatus, a water inlet drainage pipe, a water outlet flushing pipe, a drainage valve, a flushing valve, a water inlet one-way valve and a water outlet one-way valve, wherein, one end of the water inlet drainage pipe is connected with one end of the water treatment apparatus, the other end of the water inlet drainage pipe is divided into two paths which are connected with the water inlet one-way valve and the drainage pipe, one end of the water outlet flushing pipe is connected with the other end of the water treatment apparatus, the other end of the water outlet flushing pipe is divided into two paths which are connected with the water outlet one-way valve and the flushing valve, and the water outlet one-way valve and the flushing valve are connected in parallel and then are connected with a back flushing source. The utility model is suitable for water treatment equipment and has the advantages that the water treatment apparatus with one-way valve simplifies an operating program, is hard to generate misoperation and is favorable to the automation of the treatment of water.
Description
The utility model relates to a kind of water quality treater.
Existing water quality treater, for example the mechanical filter described in the 20th page in " water supply and drainage design manual (the 4th) " of China Construction Industry Press's publication has water intaking valve, outlet valve, flush valve and four valves of wash water valve.When purifying waste water, need open water intaking valve and outlet valve, close flush valve and wash water valve simultaneously.When blowdown, need close water intaking valve and outlet valve earlier, open flush valve and wash water valve then, carry out blowdown.This kind structure, operate more numerous, for not yet done in the operation the people, be easy to generate error.
The purpose of this utility model is to provide a kind of water quality treater that has check valve.
The purpose of this utility model is achieved in that a kind of water quality treater that has check valve, comprises water quality treater, water inlet blow-off pipe, water outlet washpipe water inlet check valve, wash water valve, water outlet check valve and flush valve.One end of water inlet blow-off pipe is connected with the normal feed-water end of water quality treater, feeds an end of the normal water inlet of water quality treater inner chamber, and the other end of water inlet blow-off pipe divides two-way to be connected with wash water valve with the water inlet check valve respectively.One end of water outlet washpipe is connected with the normal water side of water quality treater, feed the normal water side of water quality treater inner chamber, the other end of water outlet washpipe divides two-way to be connected with flush valve with the water outlet check valve respectively, the water side pass-out water head-tank of water outlet check valve, the other end of flush valve is communicated with the counterflush source, is connected with the water side of water outlet check valve simultaneously.The counterflush source can be a head-tank, also can be the counterflush pump.Water quality treater can be following a kind of in the array apparatus: unidirectional strainer, Two-layer filter, little flocculation direct filtration device, biological adsorption filter, physical and chemical adsorption strainer.
When normal operation, wash water valve and flush valve are all closed.Current from the water source flow into water quality treater through the water inlet check valve, flow out through the water outlet check valve.When counterflush, generalized case, the no pressure of water source cutout, and the pressure in counterflush source is closed the water outlet check valve, if flush valve this moment and wash water valve are opened, then the current of counterflush are gone into the water quality treater through the flush valve reverse direction flow and are carried out counterflush, and dirt is discharged by wash water valve, and the check valve of intaking simultaneously cuts out.
The utility model has the advantages that and simplified schedule of operation, need only open flush valve and wash water valve and need not close water intaking valve and outlet valve, but just blowdown be difficult for producing wrong-way, help the automatization of water treatment procedure.Be applicable to water treating equipment.
Fig. 1 is a structure iron of the present utility model.Fig. 1 is described as follows: 1 is water quality treater, and 2 are the water inlet blow-off pipe, and 3 are the water outlet washpipe, and 4 are the water inlet check valve, and 5 is wash water valve, and 6 are the water outlet check valve, and 7 are flush valve.
An embodiment of the present utility model 1 is described below in conjunction with the accompanying drawings: water quality treater 1 is a water filtering device, water inlet blow-off pipe 2 is contained in the upper end of water conditioning 1, feed the upper end of filtering layer in its inner chamber, the other end of water inlet blow-off pipe 2 divides two-way to connect water inlet check valve 4 and wash water valve 5 respectively, water outlet washpipe 3 is connected with the lower end of water quality treater 1, the lower end of filtering layer in the water flowing matter treater inner chamber, the other end of water outlet washpipe 3 divides two-way to connect water outlet check valve 6 and flush valve 7 respectively.The water side pass-out water head-tank of water outlet check valve 6, the other end of flush valve 7 is communicated with the counterflush source, is communicated with the water side of water outlet check valve 6 simultaneously.
