Description

RO reverse osmosis water hammer prevention device

Technical Field

The utility model relates to a fluid element field especially relates to a waterproof hammer device of RO reverse osmosis.

Background

The water hammer effect means that the inner wall of the water pipe is smooth and water flows freely inside the water pipe. When the opened valve is suddenly closed, the water flow generates a pressure on the valve and the pipe wall, mainly the valve. Because the pipe wall is smooth, the follow-up water flow quickly reaches the maximum under the action of inertia and generates destructive action, namely 'water hammer effect' in water conservancy, namely positive water hammer. The factor is considered in the construction of water conservancy pipelines. On the contrary, after the closed valve is suddenly opened, a water hammer, called a negative water hammer, is generated, and has certain destructive power, but the water hammer is not as large as the negative water hammer.

RO is an abbreviation for Reverse Osmosis in english, meaning Reverse Osmosis in chinese. In general, water flows from a low concentration to a high concentration, and after the water is pressurized, the water flows from the high concentration to the low concentration, i.e., the so-called reverse osmosis principle.

The mode of establishing the check valve through adding in the current water pipe reduces the influence of water hammer effect to the water pipe, and current check valve is when placing the water hammer, mostly through the bullet head with reduce the intraductal diameter to exert elastic force to the bullet head and realize the one-way of rivers and pass through, after the shaping, be difficult to dismantle, make to maintain very difficulty.
