Background technology
In the field such as chemical industry, pharmacy, the use of check-valves is seen everywhere.Check-valves is also known as check (non-return) valve, check valve or check
Valve, its effect is the function preventing medium directed flow in pipeline and will not flowing backwards.The operation principle of spring loaded check valve is,
Liquid is flowed into valve body by import, relies on the spring controlled flap of pressure jack-up, and after distress resolves, flap is depressed by spring force, envelope
Close liquid to flow backwards.But, find during common installation that when Pipe installing valve pipeline is too short, does not has Telescopic, it is necessary to again
Pipe laying, at this moment increases and installs labour force, and installation effectiveness is low, causes the waste of cost, and check-valves belongs to a kind of automatic valve,
Its Main Function is to prevent medium from flowing backwards, prevent pump and drive motor reversion, and the releasing of vessel media, and is fluid control
The primary element of engineering, is widely used in fluid line, and traditional check-valves either swing check valve (revolves according to center of gravity
Turn) all there is a total shortcoming with lift check valve (moving along axis), it is simply that and foreign body is more, causes without filtering function
During backflow, sealing gasket is easily blocked by foreign body and causes leakage serious, wastes water source, it is therefore necessary to improve said structure,
To bring good economic benefit to user.
