Film effluent non-backpressure water purifier

Abstract

The invention provides a film effluent non-backpressure water purifier which comprises a film processor, a water pressure type water storage tank, a low-flow rate throttle valve, a flush valve, a water inlet valve, a drainage valve, a one-way valve and an electrical control device; a purified water outlet of the film processor is respectively communicated with a purified water chamber of the water pressure type water storage tank and an inlet of the one-way valve through a purified water pipeline, a concentrated water outlet of the film processor is respectively communicated with outlets of the flush valve and the low-flow rate throttle valve, and outlets of the flush valve and the low-flow rate throttle valve are firstly and mutually communicated with each other and then are respectively communicated with a concentrated water chamber of the water pressure type water storage tank and an inlet of the drainage valve; the water inlet valve is arranged on a water inlet pipeline of the film processor; the electrical control device comprises a first pressure switch and a second pressure switch and is used for controlling the opening and the closing of the water inlet valve, the drainage valve and the flush valve; the first pressure switch is arranged on the purified water pipeline; the second pressure switch is arranged on a pipeline of the outlet of the one-way valve. Compared with the prior art, the film effluent non-backpressure water purifier provided by the invention is low in development cost and manufacturing cost, high in reliability and convenient to popularize and apply.

Description

technical field [0001] The invention relates to the field of water purification equipment, in particular to a membrane water outlet and no back pressure water purifier. Background technique [0002] The application of household reverse osmosis water purifiers has become increasingly popular. The reverse osmosis membranes used in most models are small-area membranes. The water flow of the membrane modules of such small-area membrane water purifiers is relatively small during water production. To meet the large flow requirements required by users for water intake, it is usually solved by setting up a compressed air storage tank. When the water is produced by the machine, the outlet water flows into the compressed air storage tank for storage. When the user needs water, he takes it from the compressed air storage tank. Putting water in the tank can obtain a satisfactory high flow rate. However, when the water is produced by the machine, the water outlet of the membrane module...

Problems solved by technology

The main problem of this method is that the four-sided valve is sometimes not closed tightly, causing the machine to leak water for a long time

The problem with this method is that the structure of the special multi-channel pipeline switching valve is relatively complicated. After a period of use, the sealing ring will gradually wear and tear, resulting in unreliable sealing and water leakage, or in order to make the special multi-channel pipeline switching valve obtain better The durability makes the manufacturing cost very high and the cost performance is low

The problem with this method is that an electronically controlled water outlet that is compatible with the system is required, which is not a water outlet commonly used in the industry at present, that is, it is not compatible with the current general water outlet; if a water outlet with a linkage mechanism is used, Then the faucet may also have to adapt to the product shape, and it is also a special faucet, which is also incompatible with the current general faucet.

Both situations lead to high product development costs and manufacturing costs, which are not conducive to mass promotion and application
