Description
Technical field
The utility model relates to the waste water ratio in the pure water equipment, is specifically related to a kind of waste water ratio of adjustable pressure.
Background technology
Carry out in the appliance water product of purification of water quality processing in the employing Reverse Osmosis Technology, water purification machine is exactly a midget plant that makes pure water, as shown in Figure 1, consist predominantly of activated charcoal filter 1 (filter core I, filter core II, filter core III), topping-up pump 2, reverse osmosis membrane pipe (RO film pipe) 3 and waste water in its purification system than devices such as 4.Because the RO membrane pore size in the RO film pipe has only 0.0001-0.001 micron, be dissolved in most inorganic salt (comprising heavy metal) organism in the water and bacterium, virus etc. and all can't see through the RO film.RO film pipe as core, by the pressurization of RO film pipe front end topping-up pump and the back-pressure effect of condensed water output terminal waste water ratio, the tap water of the enough pressure of tool of input RO film pipe, be separated into through the pure water of RO film and the condensed water that can't see through by strict, thereby reach the purpose that purifies water, produces pure water.
Because the characteristic of RO film and RO film pipe itself, its manufacturer all stipulates clear and definite working pressure range, the voltage stabilizing condition, parameters such as water temperature, and on-the-spot water inlet pipe pressure reduction, the temperature difference, water quality etc. all have bigger difference, this not only installs to field adjustable and has increased very big difficulty, also may directly have influence on the result of use of RO filter membrane itself, in fact, the following life-span of environment and the tangible phenomenon of water treatment difference on effect that just exist same RO water purification machine to press at different water inlet pipes, trace it to its cause, be that to a great extent RO water purification machine manufacturer has ignored and the supporting Primary Component of RO film pipe---the serviceability that compares etc. of topping-up pump and waste water especially, the existing topping-up pump of selecting for use can supercharging can not be regulated or can not automatic pressure regulation, waste water is fixed than the pressure limiting ability of (or traditional pin type variable valve), traditional RO water purification machine technology can't reach constant at all or adjust the index of water pressure, the awp of RO film is difficult to stablize, and the pressure excessive RO of causing film rupture inefficacy or the low phenomenon of the too small water production rate of pressure happen occasionally in the use.
The utility model content
The purpose of this utility model is to provide a kind of pressure regulating type waste water ratio; when intake pressure is not normal, can regulate pressure limiting automatically, rush down pressure with unlikely the breaking of protection RO film; ensure the stable operating pressure state of RO film pipe, improve the working efficiency of water purification machine and prolong work-ing life of water purification machine.
In order to solve above technical problem, technical solution adopted in the utility model is: the waste water ratio comprises main valve body and pressure regulation assembly, main valve body is provided with entery and delivery port and pressure regulating cavity, entery and delivery port communicates by pressure regulating cavity, the sealing of pressure regulation assembly is installed on the pressure regulating cavity, and this pressure regulation assembly comprises a valve pocket and be installed on the interior elasticity pushing block of cover that the valve pocket top is equipped with screw, this screw stretches into and withstands the elasticity pushing block in the valve pocket, but the bottom of this elasticity pushing block is provided with the gasket of shutoff pressure regulating cavity.
The utility model that parameter is complementary is installed on the RO water purification machine, change the pressure limiting dynamics by adjusting the top screw degree of depth, during use, change topping-up pump output hydraulic pressure especially when surpassing RO film plumber and making pressure at pressure of water network, the high-pressure thick that the surpasses voltage limiting value gasket that backs down pressure regulating cavity of the intake antrum from the utility model main valve body that shrinks, nationality is discharged by water outlet, thereby is reached the purpose of rushing down pressure automatically to connect water exit.
