Description

Reverse osmosis water hammer preventing device

Technical Field

The utility model relates to the technical field of fluid elements, in particular to a reverse osmosis water hammer preventing device.

Background

The prior art has the following problems:

the water hammer effect means that the inner wall of the water pipe is smooth and the water flow is free. When the open valve is suddenly closed, the water flow will generate a pressure against the valve and the pipe wall, mainly the valve. Because the pipe wall is smooth, the subsequent water flow rapidly reaches the maximum under the action of inertia and generates a destructive action, namely a 'water hammer effect', namely a positive water hammer in the water conservancy. This factor is considered in the construction of hydraulic pipelines. Conversely, when the closed valve is suddenly opened, a water hammer, called a negative water hammer, is also generated, and a certain destructive force is also generated, but the water hammer is not large.

The current waterproof hammer device often blocks the follow-up flow of rivers through the elasticity effect of spring when tap closes, blocking effect is showing, but rivers are the sustainable flow object generally, at tap closes an instant, rivers can continue to flow because of inertia, thereby last with valve top upper portion, and then lead to the valve to close inadequately in time, lead to the water hammer effect to cause the injury to follow-up water pipe wall through the valve at will, the pressure of messenger superpressure water can not be fine is released, and the mounting means of current waterproof hammer device often adopts welded mode to install in tap's front end, the mounting means step is loaded down with trivial details, often need professional personnel to install, it is very troublesome, need improve urgently.
