Description
Technical field
The utility model relates to technical field of water purification, particularly a kind of RO membrane filtration cylinder valve head with waste water proportional valve function.
Background technology
RO (reverse osmosis counter-infiltration) film is when pure water processed, waste water can be produced, ratio between wastewater flow and pure water flow must be fixed, the work of RO film ability normal table, this just requires that waste water is under normal pressure (0.42Mpa), with fixing volume exhaust, consume the energy of high pressure simultaneously; The RO filter flask now commercially used, discharge of wastewater hole is simple through hole, does not possess this function, can only connect a general waste water proportional valve part outside again.
The principle of waste water proportional valve is: plastic casing is PE pipe quick connector, and there is one section of metal capillary centre, and current pass through from its pore; Design internal diameter and the length of metal capillary, just can make current under standard pressure, pass through with the firm discharge needed from capillary, the energy of high pressure is consumed in by the engineering of capillary simultaneously.
Utility model content
The purpose of this utility model is to improve existing RO membrane filtration cylinder valve head, realizes automatically measuring, the RO membrane filtration cylinder valve head of the measurement difference band waste water proportional valve function avoiding manual operation to bring.
For achieving the above object, the utility model provides a kind of RO membrane filtration cylinder valve head with waste water proportional valve function, comprise: the outlet of body, tap water inlets, pure water, wastewater outlet, the outlet of described tap water inlets, pure water, wastewater outlet are all located on body, waste water proportioning device is set in described wastewater outlet, described waste water proportioning device is the waste water hole of a stepped distribution in aperture, and the aperture of described waste water hole reduces successively along water (flow) direction.
Preferably, the non-return device being arranged at pure water outlet or tap water inlets can also be comprised.
Preferred, described non-return device comprises soft rubber plug and fixture, described soft rubber plug is fixed in pure water outlet or tap water inlets by fixture, described soft rubber plug one end is dish shaped in form, the direction that its dish mouth flows out towards water, the other end coordinates fixing described non-return device in tap water inlets or pure water export with described fixture.
The beneficial effects of the utility model: the waste water proportioning device of RO membrane filtration cylinder valve head directly in RO membrane filtration cylinder valve head wastewater outlet of band waste water proportional valve function of the present utility model is integrated with the function of proportioning valve; By calculating required pore size, waste water hole is directly designed to required aperture, and current by this hole, are embodied directly in the object by firm discharge water outlet under normal pressure, the aperture of echelon gradual change can better absorb current high-pressure energy simultaneously, prevents noise etc.
In order to further understand feature of the present utility model and technology contents, refer to following about detailed description of the present utility model and accompanying drawing, but accompanying drawing only provide reference and explanation use, is not used for being limited the utility model.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, by describing in detail detailed description of the invention of the present utility model, will make the technical solution of the utility model and other beneficial effect apparent.
In accompanying drawing,
Fig. 1 is the front view of the RO membrane filtration cylinder valve head of the utility model band waste water proportional valve function;
Fig. 2 is the profile at A place in Fig. 1;
Fig. 3 is the profile at B place in Fig. 1.
Detailed description of the invention
For further setting forth the technological means and effect thereof that the utility model takes, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
Refer to Fig. 1 and 2, the utility model provides a kind of RO membrane filtration cylinder valve head with waste water proportional valve function, comprise: body 10, tap water inlets 20, pure water outlet 30, wastewater outlet 40, described tap water inlets 20, pure water outlet 30, wastewater outlet 40 are all located on body 10, in described wastewater outlet 40, waste water proportioning device 42 is set, described waste water proportioning device 42 is the waste water hole of a stepped distribution in aperture, and the aperture of described waste water hole reduces successively along water (flow) direction.
The described step number of waste water proportioning device 42 and the aperture of each ladder need to select according to pressure, by waste water hole being directly designed to echelon shape aperture, allowing waste water under standard pressure, passing through with the firm discharge needed, waste water is in the process passed through simultaneously, consumes the energy of high pressure.
Refer to Fig. 3, the non-return device 50 being arranged at tap water inlets 20 or pure water outlet 30 can also be comprised, described non-return device 50 comprises soft rubber plug 52 and fixture 54, described soft rubber plug 52 exports 30 by fixture 54 and tap water inlets 20 or pure water and fixes, described soft rubber plug 52 one end is dish shaped in form, the direction that its dish mouth flows out towards water, the other end fixedly fills 54 and puts with described and coordinate fixing described non-return device 50 to export in 30 in tap water inlets 20 or pure water.
When water is from outflow, current wash away described soft rubber plug 52 one end by the bottom of dish to dish mouth direction, and disk like position produces the deformation drawn close to centre, thus allow water outlet path, so that current pass through, when water refluxes, current wash away check end by dish mouth to direction at the bottom of dish, disk like position produces the deformation expanded to the periphery, soft rubber plug 52 is pressed on path by hydraulic pressure, plays sealing function, current not by, thus block water route, to reach the object of check current.
In sum, the waste water proportioning device of the RO membrane filtration cylinder valve head of band waste water proportional valve function of the present utility model directly in RO membrane filtration cylinder valve head wastewater outlet is integrated with the function of proportioning valve; By calculating required pore size, waste water hole is directly designed to required aperture, and current by this hole, are embodied directly in the object by firm discharge water outlet under normal pressure, the aperture of echelon gradual change can better absorb current high-pressure energy simultaneously, prevents noise etc.
The above; for the person of ordinary skill of the art; can make other various corresponding change and distortion according to the technical solution of the utility model and technical conceive, and all these change and be out of shape the protection domain that all should belong to the utility model claim.
