Abstract
The utility model relates to an RO membrane filter with a needle valve adjuster, which solves the technical problem of providing an RO membrane filter with a needle valve adjuster which has the advantages of easy regulation, easy locking, few connection points, less water leakage and high universality. The utility model has the technical proposals that the RO membrane filter with a needle valve adjuster is provided with a vertical hollow cylindrical casing and a built-in reverse osmosis membrane filter core; the upper end of the casing is fixed with a sealing ring and a casing cover through two semi-circle involutory fixing clips; the top of the casing cover is provided with a water inlet joint; the lower end of the casing is provided with two pipelines which are vertical to and communicated with the casing, wherein one is a waste water pressure pipe, the end of which is provided with a waste water outlet, and the other one is a purified water outlet pipe, the end of which is a purified water outlet. The utility model is characterized in that the inner side of a cavity of the other end of the waste water pressure pipe is provided with a needle-shaped waste water adjusting valve; the needle-shaped waste water adjusting valve is fixedly connected with the fixed waste water pressure pipe through an adjusting valve spacing plate and an adjusting screw. The utility model can be used in a water treatment process.
Description
Technical field
The utility model relates to water treatment facilities, especially a kind of RO film filter that has the needle valve adjuster.Be applicable in the water treatment technology.
Background technology
The RO counter-infiltration is a kind of reverse travel motion of infiltration, is a kind ofly to drive down the separation method that the selection crown_interception by means of pellicle separates solute in the solution and solvent at pressure, and its aperture is greatly between 1/1000～1/10000 micron.It has been widely used in the purification of various liquid with concentrated, wherein the most general application example is in water treatment technology, can be with reverse osmosis technology with Impurity removals such as the inorganic ions in the former water, bacterium, virus, organic matter and colloids, to obtain high-quality pure water.At present most widely used is the rolling polyamide composite film, and its water flux and removal efficiency can be stressed, the influence of temperature, the rate of recovery, water inlet salt content and pH value etc.In order to regulate the speed of water by reverse osmosis membrane, existing filter adopts the needle valve of independent external usually, owing to be difficult to locking, therefore regulate difficulty, when nut screwing clamping, needle valve just is offset the position that mixes up, and moving of a little all can cause very big changes in flow rate; Its two, external valve has two joints and pipe, and drainage takes place easily in the junction; Its three, need different specified flow limiters for the water of different degrees of purity, different pressures, the method that adopts is to mate one by one at present, certainly will need the flow limiter of plurality of specifications.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of easy adjusting, locking easily are provided; Few, the antileaking of tie point; The RO film filter that has the needle valve adjuster of highly versatile.
The technical scheme that the utility model adopted is: the RO film filter that has the needle valve adjuster, housing with vertical hollow cylindrical, built-in reverse osmosis membrane filtration core, housing upper end by two semicircles involutory fixedly fasten sealing ring and cap, water supply connector is arranged at the top of cap; The housing lower end is two perpendicular and communicate pipelines, wherein one is the waste water force pipe, its end has wastewater outlet, another root is the outlet pipe of purifying waste water, its end has treated water outlet, it is characterized in that being equipped with in the other end chamber of waste water force pipe aciculiform waste water control valve, this valve is connected and fixed by control valve limiting plate and adjustment screw and fixing waste water force pipe.
Described its shape of aciculiform waste water control valve is as a screw, and the diameter maximum of valve head shortens cylinder in the valve rod, and preceding half is smooth and be with " O " shape sealing ring, back half have external screw thread and angle very little be transited into cone, the valve tail is sharp-pointed aciculiform.
Described control valve limiting plate is strip, is close to the end face of the valve head of aciculiform waste water control valve.
The beneficial effects of the utility model are: because aciculiform waste water control valve of the present utility model is to be built in the waste water force pipe, can be described as with force pipe itself and be made of one good stability; In addition, this needle valve is shrunk to backshank with very little angle, allows to regulate gradually, so force pipe is not allowed movability when regulating, harmonizes easily, easily locking.Built-in valve has two joints and pipe unlike external, because tie point is few, therefore is not easy to leak.Can regulate the position of needle valve according to water different degrees of purity and different pressures, and not need to do the flow limiter of a lot of different sizes, thereby save use cost.

The specific embodiment
As shown in Figure 1, present embodiment has the housing 1 of vertical hollow cylindrical, and built-in reverse osmosis membrane (RO film) is crossed filter core 15, and the housing upper end is by two fixedly card 2 usefulness screws, 3 fixed seal rings 4 and caps 5 that semicircle is involutory, and water supply connector 6 is arranged at the top of cap.The housing lower end is two perpendicular and communicate pipelines, wherein one is waste water force pipe 7 (1/4 inch), its end has wastewater outlet 9, another root is the outlet pipe 8 (1/4 inch) of purifying waste water, its end has treated water outlet 10, aciculiform waste water control valve 11 is housed in the other end chamber of waste water force pipe 7, its shape is as a screw, the diameter maximum of valve head, shorten cylinder in the valve rod into, preceding half is smooth and be with two " O " shape sealing rings 14, and back half has external screw thread and is transited into cone with very little angle gradually, and the valve tail is sharp-pointed aciculiform (not threaded).This valve is connected and fixed with the waste water force pipe of fixing 7 by control valve limiting plate 12 and adjustment screw 13, and described control valve limiting plate 12 is strip, is close to the end face of the valve head of aciculiform waste water control valve 11, in case control valve rotates voluntarily or under other situation.
The water treatment capacity of regulating filter needs test, corresponding to 50 gallons, the 75 gallons water with different amounts such as 100 gallons, different RO films is arranged, and in addition, also will consider the degree of purity (PPM) of pressure, temperature and the water of water.By writing time and capacity, in case whether the result who is easy to calculate adjusting made general adjusting, subsequently does accurate adjustment near correct output area again, so just increase the output quantity of pure water, also reached the output quantity of correct waste water simultaneously.Desirable ratio is a pure water 30%, waste water 70%.
