Description
Technical field
The utility model relates to pneumatic element technical field, in particular to a kind of high voltage precision filter.
Background technique
In pneumatic element field, compressed-air filter is a kind of moisture filter by compressed air and the gas that is discharged
Source processing element, compressed air humidity that treated reduce, and can prevent inner wall of the pipe and gas control component spool from corroding.Compressed air
Filter mainly includes filter body, filter core, cup and drainage mechanism, and filter body is equipped with compressed air inlet and goes out
Mouthful, compressed air enters inside filter body from import, then after filter element filtering, and dry air is discharged from outlet, and moisture is received
It combines in cup, the water in cup is finally discharged from drainage mechanism.
But existing filter, it is only filtered by filter core, poor filtration effect, the water in air cannot be completely removed
Point, furthermore the drainage mechanism of common compressed-air filter has Manual draining valve, spring drainage mechanism and float-type automatic
Drainage mechanism.Manual drainage valve arrangement is most simple, strikes valve opening when needing to drain with the hand, closes valve after drained water.There are commonly
Knob small ball, push button ejector pin valve etc..This kind of valve design is simple, as long as solving sealing problem.Hand-operated valve one
Surely manual operation is wanted, it is necessary to inspect periodically water level and drain in time.If draining is not in time, it will cause secondary pollution, do not have
Water filtering function, the Manual draining valve is at low cost, and draining rapidly, does not influence to work normally, but the cost of manual maintenance is high.Spring row
When water dispenser structure, no air pressure or extremely low air pressure, spring jacks up spool draining.When having air pressure, spool is forced on O type sealing ring,
Stop draining.The spring drainage mechanism must stop the supple of gas or steam in draining, can be used only in certain places that can frequently stop the supple of gas or steam, advantage
It is not have to manual control, manufacturing cost is low.
Float-type automatic draining mechanism, cup is interior to be equipped with float, and the pressure of compressed air, float lower end are born in float upper end
The buoyancy of water is born, when the water level in cup increases so that the lower end buoyancy of float is greater than upper end pressure, float is moved up and controlled
Discharge outlet is opened, when water level decreasing makes the lower end buoyancy of float be less than upper end pressure, float moves down and controls discharge outlet pass
It closes, to realize Auto-drainage.The float-type automatic draining mechanism structure is more complex, and service life is not grown, and production cost
Height, maintenance not easy to assemble.
