Description
Technical field
The utility model relates to technical field of water purification, particularly a kind of RO membrane filtration cylinder valve head with reverse checkvalve function.
Background technology
The now valve head of RO (reverse osmosis reverse osmosis) membrane filtration bottle commercially, is be not with reverse checkvalve function in pure water outlet, needs to increase a reverse checkvalve part again.The principle of reverse checkvalve part is: plastic casing is PE pipe quick connector, middle hard-pressed bale metal reverse checkvalve; Metal reverse checkvalve is made up of metal shell, removable pin, spring, snap ring, sealing-ring; Current along reverse checkvalve direction flowing time, promote removable pin, compression spring, sealing-ring is pushed out metal shell, no longer seals, and current pass through smoothly; When current flow against reverse checkvalve direction, spring force and hydraulic pressure act on simultaneously, promote removable pin press seal circle, current not by.
Because needs arrange separately reverse checkvalve part, its complex structure is installed loaded down with trivial details, the many parts of needs and many installation procedures when causing valve head to use, cost is higher, and the reason such as error owing to installing, sealing property can be caused to weaken, thus affect check effect.
Utility model content
The purpose of this utility model is to improve existing RO water purifier valve head, obtains a kind of check effective, and structure is simple, installs the RO membrane filtration cylinder valve head being easy to band reverse checkvalve function.
For achieving the above object, the utility model provides a kind of RO membrane filtration cylinder valve head with reverse checkvalve function, comprise: body, tap water inlets, pure water exports, wastewater outlet, described tap water inlets, pure water exports, wastewater outlet is all located on body, in described pure water outlet, non-return device is set, described non-return device comprises soft rubber plug and stationary installation, described soft rubber plug is fixed in the outlet of described pure water by stationary installation, described soft rubber plug comprises inboardend and check end, described check end is dish shaped in form, the direction that its dish mouth flows out towards pure water, be connected with described inboardend at the bottom of the dish of described check end, described inboardend coordinates fixing described non-return device in pure water exports with described stationary installation.
Preferably, described stationary installation is pin, and described inboardend is provided with through hole, and described pin runs through the through hole of described inboardend, and is arranged in pure water outlet.
Preferably, described pure water exit arranges pickup groove, slightly follows closely with fixing.
Preferably, described non-return device is also arranged in tap water inlets or wastewater outlet.
Preferably, waste water proportional valve is provided with in described wastewater outlet.
The beneficial effects of the utility model: the RO membrane filtration cylinder valve head of band reverse checkvalve function of the present utility model, are directly integrated with non-return device in original RO membrane filtration cylinder valve head pure water outlet; This non-return device comprises soft rubber plug and stationary installation, described soft rubber plug comprises inboardend and check end, and described check end is dish shaped in form, the direction that its dish mouth flows out towards pure water, stationary installation plays fixing soft rubber plug position, and soft rubber plug plays reverse checkvalve effect; When pure water flows out from pure water outlet, current wash away check end by the bottom of dish to dish mouth direction, and the check end of disk like produces the deformation drawn close to centre, thus allow water outlet path, so that pure water passes through, when pure water refluxes, current wash away check end by dish mouth to direction at the bottom of dish, the check end of disk like produces the deformation expanded to the periphery, check end is pressed on pure water outlet opening by hydraulic pressure, plays sealing function, current not by, thus block water route, to reach the object of check current; Its check is effective, and structure is simple, installs easily, can be formed simultaneously and assemble in the process of producing RO water purifier valve head, do not need complicated reverse checkvalve part and independent assembling process, thus reduce cost.
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 embodiment 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 reverse checkvalve function;
Fig. 2 is the sectional view at A place in Fig. 1;
Fig. 3 is the perspective view of the soft rubber plug of the RO membrane filtration cylinder valve head of the utility model band reverse checkvalve function.
Embodiment
For further setting forth the technique 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. 2, the utility model provides a kind of RO membrane filtration cylinder valve head with reverse checkvalve 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 is all located on body 10, in described pure water outlet 30, non-return device 32 is set, described non-return device 32 comprises soft rubber plug 322 and stationary installation 324, described soft rubber plug 322 is fixed in described pure water outlet 30 by stationary installation 324, described soft rubber plug 322 comprises inboardend 326 and check end 328, described check end 328 is dish shaped in form, the direction that its dish mouth flows out towards pure water, be connected with described inboardend 326 at the bottom of the dish of described check end 328, described inboardend 326 coordinates fixing described non-return device 32 to export in 30 in pure water with described stationary installation 324.
When pure water flows out from pure water outlet 30, current wash away check end by the bottom of the dish of described check end 328 to dish mouth direction, the check end 328 of disk like produces the deformation drawn close to centre, thus allow water outlet path, so that pure water passes through, when pure water refluxes, current wash away check end 328 by by described check end 328 dish mouth to direction at the bottom of dish, the check end 328 of disk like produces the deformation expanded to the periphery, hydraulic pressure check end 328 is pressed on pure water outlet 30 on, play sealing function, current not by, thus block water route, to reach the object of check current.
