Description
Technical field
The utility model relates to check-valves technical field, specially a kind of spring loaded check valve structure.
Background technique
Check-valves refers to opening and closing element for round flap and by own wt and pressure medium generation movement to block medium to fall
A kind of valve of stream.Belong to automatic valve class, also known as non-return valve, check valve, return valve or isolating valve.Flap motion mode is divided into lifting
Formula and swing type.Lift check valve is similar with stop valve structure, only lacks the valve rod for driving flap.Medium from input end (under
Side) it flows into, it is flowed out from outlet end (upside).When inlet pressure is greater than the sum of flap weight and its flow resistance, valve is opened
It opens.Conversely, valve is then closed when medium is flow backwards.Swing check valve has a flap that is tilting and being pivoted, and work is former
It manages similar to lift check valve.Check-valves is commonly used for the bottom valve of water plug, can prevent the reflux of water.Only consolidate valve and cut-off
Valve is applied in combination, and can play the role of security isolation.The application of spring loaded check valve is more general in the check-valves of all multiple types
Time, its working principle is that: medium enters valve body by arrival end, pushes valve rod, spool to move upwards, valve opening；When medium by
When outlet end is flowed back, spool, valve rod act rapidly under the effect of the pressure of spring force and medium, and valve is closed.To economize on resources,
Valve body structure part is replaced in convenient dismounting, and improves the comprehensive utilization ratio of single valve member, the Combination Design and application of check-valves
