Abstract
The utility model discloses a structure capable of preventing internal negative pressure of a reverse osmosis membrane caused by siphonage. The structure comprises a reverse osmosis system; produced water of the reverse osmosis system is connected with a purified water tank by a purified water pipeline; thick water of the reverse osmosis system is connected with a thick water tank by a thick water pipeline; a unidirectional air intake valve is installed on the highest part of the thick water pipeline. When the system runs, the unidirectional air intake valve is in a natural closed state because of pressure in the pipeline, and thus water in the pipeline is prevented from leaking; when the system stops running, the negative pressure formed in the pipeline enables the unidirectional air intake valve to be in an open state when the siphonage forms, air enters the pipeline, and thus the generation condition of the siphonage is damaged; the unidirectional air intake valve starts or closes according to the variation of pressure, and the power consumption of the system cannot be increased; because the size of the valve is very small, the size and the weight of the pipeline cannot be increased, and the modification of the reverse osmosis technology is very economical and effective.
Description
Technical field
The utility model relates to reverse osmosis technology field, is specifically related to a kind ofly prevent that siphonage from causing the structure of negative pressure in reverse osmosis membrane.
Background technology
Existing reverse osmosis technology; if produce water and concentrated water spout, there is larger liquid level difference, during system-down, there will be siphonage to make to occur negative pressure while again starting shooting, easily occurring that water hammer produces very large water impact load in reverse osmosis membrane; reverse osmosis membrane is caused to damage, affect its work-ing life.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art; the purpose of this utility model is to provide a kind of and prevents that siphonage from causing the structure of negative pressure in reverse osmosis membrane; in the time of effectively preventing that reverse osmosis equipment from shutting down because pipeline siphonage causes negative pressure in film, the damage of water hammer to film while reducing to start shooting.
In order to achieve the above object, the technical scheme that the utility model is taked is:
A kind ofly prevent that siphonage from causing the structure of negative pressure in reverse osmosis membrane, comprise reverse osmosis system 1, the product water of reverse osmosis system 1 is connected by pure water pipeline with pure water tank 2, the dense water of reverse osmosis system 1 is connected with dense water tank 3 by dense waterpipe, and breather cheek valve 4 is arranged on the dense waterpipe being at the highest notch.
The utility model destroys system pipeline due to the siphonage that liquid level difference forms by breather cheek valve, prevents because siphon forms negative pressure in reverse osmosis system film, avoids reverse osmosis membrane because of large hydraulic load, to cause damage when start.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
With reference to accompanying drawing, a kind ofly prevent that siphonage from causing the structure of negative pressure in reverse osmosis membrane, comprise reverse osmosis system 1, the product water of reverse osmosis system 1 is connected by pure water pipeline with pure water tank 2, the dense water of reverse osmosis system 1 is connected with dense water tank 3 by dense waterpipe, and breather cheek valve 4 is arranged on the dense waterpipe being at the highest notch.
Principle of work of the present utility model is:
During system operation, because the pressure in pipeline makes breather cheek valve 4 in natural closing condition, prevent pipe leakage; When system stops, the negative pressure forming in pipeline while forming due to siphonage makes breather cheek valve 4 in opened condition, thereby air is entered, pipeline has destroyed the generation condition of siphonage.Breather cheek valve 4 is opened or closed by the variation of pressure, can not increase the power consumption of system, because volume is very little, also can not increase conduit volume and weight, with it, to existing reverse osmosis process transformation, is very cost-effective.
Claims (1)
