Abstract
The invention discloses a wastewater ratio of pressure-adjustable type, which comprises a main value body (12) which is provided with a water inlet and a water outlet (21, 25), and a regulating chamber (26). The water inlet and water outlet are communicated through the regulating chamber. A pressure regulating component is mounted on the regulating chamber. The pressure regulating components comprise a value sleeve (6) and an elastic pulling block. Screws are arranged on the top of the value sleeve. The screw extends into the value sleeve and resists the elastic pulling block. The bottom of the elastic pulling block is provided with a sealed pad (11) for dealing and blocking the regulating chamber. The invention with a matched parameter is arranged on an RO prettified water machine and the pressure limitation force by adjusting the depth of the screw on the top. When being used, particularly, the changes generated by water net pressure or the output water pressure of a booster pump isbigger than the working pressure of the PO filming pipe, the high-handed compressed water which is over the pressure limited value opens the sealed chamber of the regulating chamber from the top of the water inlet chamber on the invented main value body, thus the water entering channel is run-trough. The water is drained from the water outlet and the pressure is automatically reduced.
Description
Technical field
The present invention relates to the waste water ratio in the pure water equipment, be 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 active carbon filter 1 (filter core I, filter core II, filter core III), booster pump 2, reverse osmosis membrane pipe (RO film pipe) 3 and waste water in its cleaning system than devices such as 4.Because the RO membrane aperture in the RO film pipe has only the 0.0001-0.001 micron, be dissolved in most inorganic salts (comprising heavy metal) organic matter 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 booster pump and the back-pressure effect of condensed water output waste water ratio, the running 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, being that to a great extent RO water purification machine manufacturer has ignored and the supporting Primary Component of RO film pipe---the service behaviour that compares etc. of booster pump and waste water especially: the booster pump of selecting for use in the existing water purification machine can supercharging can not be regulated or can not automatic pressure regulation, and waste water causes its pressure limiting ability to be fixed than the metering hole fixed apertures of (or traditional pin type control valve).As shown in Figure 5, in actual applications, RO film operating pressure in the water purification machine fluctuates greatly when tap water pressure changes, tap water pressure is during less than 15PSI, operating pressure is obviously on the low side, tap water pressure is during greater than 40PSI, and operating pressure is obviously higher again, even has surpassed the upper safety limit of water purification machine operating pressure.Traditional RO water purification machine technology can't reach constant at all or adjust the index of water pressure, and the actual working pressure 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 aquifer yield of pressure happen occasionally in the use.
Summary of the invention
The object of the present invention 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 operating efficiency of water purification machine and prolong service life of water purification machine.
In order to solve above technical problem, the technical solution used in the present invention 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 sealing gasket of shutoff pressure regulating cavity.
The present invention that parameter is complementary is installed on the RO water purification machine, changes the pressure limiting dynamics by adjusting the top screw degree of depth, during use, because tap water pressure cross when low, the metering hole aperture of novel waste water ratio diminishes automatically, rationally reduces the flow of dense water, to reach the purpose of voltage stabilizing; Change booster pump output hydraulic pressure especially when surpassing RO film operating pressure at pressure of water network, the high-pressure thick that the surpasses voltage limiting value sealing gasket that backs down pressure regulating cavity of the intake antrum from main valve body of the present invention that shrinks, nationality is to connect exhalant canal, discharge by delivery port, automatically increase the flow of condensed water, thereby rush down pressure automatically, RO film operating pressure is stabilized in the safe range, as shown in Figure 6.
In addition, traditional waste water is than for the water purification machine that cooperates different model uses, and the waste water that needs factory effluent amount 250--1500CC/min is than about 20 kinds, and just can not dismantle behind the finished product, also can occur big, the undesirable substandard products of many flow deviation in the production; A model of waste water ratio of the present invention promptly can be used for the multiple water purification machine of 50--1500 gallon, and production technology is unified, and finished product also can be dismantled, and can regulate in the use, and defect rate is very low, has also improved the use value of product when reducing production costs significantly.
