Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways of covering.
The present invention for filter without oil-water separating function, oil water separator can not replace filter the problem of, it is logical
Cross and filter of the prior art is transformed, filter and oil water separator is realized that function switches.
Therefore, the invention provides a kind of changeable filter for oil water separator, including outer cylinder body 1, it is described outer
Oil discharge outlet 2 and liquid level sensor installing port 3 are offered on cylinder 1, the filter includes filter state and water-oil separating
Device state；Under the filter state, filter element 4, and the oil discharge outlet 2 and liquid level are installed in the outer cylinder body 1
Sensor installation port 3 is in closed state；From top to bottom it is provided with the oil water separator state, the outer cylinder body 1
Magnetic valve 7 is installed at preposition filter core 5 and Coalescence filter core 6, and the oil discharge outlet 2, liquid is installed at the liquid level sensor installing port 3
Level sensor 8.
When as filter in use, such as Fig. 2, as long as oil discharge outlet 2 and liquid level sensor installing port 3 are blocked, in outer cylinder body
Filter element 4 is loaded onto in 1.
When as oil water separator in use, such as Fig. 3, preposition filter core 5 and Coalescence filter core 6 are integrated by inner cylinder 9
