Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
The present invention discloses a kind of diesel oil filtering transducer, hereinafter referred to as sensor, and the sensor includes the He of shell 1
Column 2, shell 1 have inner space, and one end of column 2 is arranged in the inner space.1 cup-shaped structure of shell, has bottom
Face and side, top are open design, and one end of column 2 is just arranged on bottom surface, and the other end of column 2 stretches out from the shell 1,
It is higher than the height of side.
The top of the column 2 is provided with external screw thread 3, the bottom of column 2 is provided with lower external screw thread 4, it is described
There is interval between upper external screw thread 3 and the lower external screw thread 4.Upper external screw thread 3 and lower external screw thread 4 are two groups of independent screw threads, two
Do not connected between person.Part between upper external screw thread 3 and lower external screw thread 4 is the outside of column 2.
When in use, the two is coordinated with the mouth thread of diesel fuel filter, therefore the thread rotary orientation of the two, pitch etc.
All it is identical.Upper external screw thread 3 is first screwed in diesel fuel filter oral area during use, it is noted that is unlimited at the end of upper external screw thread 3
Shape, external screw thread 3 can be made to enter in diesel fuel filter (hereinafter referred to as bavin filter), now column 2 be located at upper external screw thread 3 and it is lower outside
The oral area of outside and bavin filter, which is directly formed, between screw thread 4 is slidably matched, and can inside and outside slide.
Promote column 2 it is slided into bavin filter, until lower external screw thread 4 arrives the oral area of bavin filter, now rotated, under making
External screw thread 4 coordinates with mouth thread, realizes installation.
Level sensor is extended with the top of column 2, is installed to as described above by the diesel oil filtering transducer
In bavin filter, level sensor works, water surface site situation in bavin filter.
Illustrate the function that discharges water on the diesel oil filtering transducer below.
Column 2 is hollow structure, and top has upper shed 5, connects the hollow structure, and bottom has under shed 6, connection
The hollow structure and the inner space.Or column 2 can be understood as tubular structure.The but bottom of the tubular structure
Opening may be opened in side wall, rather than bottom surface, because the bottom surface of column 2 is attached with shell 1.
Upper shed 5 is generally located on top surface, to facilitate water to flow into, and the hollow structure based on column 2 and upper shed
5, above-mentioned level sensor can be arranged directly in hollow structure, and be stretched out from upper shed 5.
Under shed 6 can be by the aqueous reflux of releasing to shell 1, and the inner space can of shell 1 serves as the water of releasing
Interim storing place.In order to ensure that water can exclude in time, discharge outlet 11 is provided with the shell 1.
In one embodiment, upper shed 5 also has a groove in addition at the top of column 2 on the side at top,
The groove and the one of upper shed 5, also connect hollow structure, groove, to improve drainage effect, can be avoided with circumferentially arranged multiple
The water flushed with top is not easy to discharge.
Preferably, the under shed 6 is located at the lower section of the lower external screw thread 4, and below the under shed 6, is provided with
The sealing ring being set in outside the column 2.When needing draining, somewhat rotational shell 1, the lower external screw thread 4 of its drive are filtered towards bavin is departed from
Direction is moved, and gap occurs in the oral area of sealing ring and bavin filter, and now water can directly exports under shed 6.The size of flow
It can be determined according to amount of spin.When discharge capacity is larger, lower external screw thread 4 can be screwed off completely, external screw thread 3 is connected with oral area
Connect, i.e., sensor will not be made to drop, and can facilitates draining, but is screwing off lower external screw thread 4, is filtered from the center section of column 2 and bavin
Oral area when coordinating, clearance leakage that may be between oral area and column 2.
It is to be understood that bavin filter oral area is opened in the bottom of whole bavin filter, sensor of the invention is also to be installed from bottom,
Because the density ratio oil of water is big, therefore water can could so be arranged underlying water by the structure of column 2 in the lower section of oil
Put.
Level sensor has two conductive probes 9 being spaced, and the conductive probe 9 is stretched from the top of column 2
Go out.Different with the density of water with reference to above-mentioned oil, water can be located at lower section, and with the increase of dampening, water level also can be raised slowly, until water
To be increased to conductive probe 9, because the resistance of water and oil is also different, when water is increased to conductive probe 9, pass through oil conducting originally
Two conductive probes 9, are changed to turn on by water, and resistance therebetween changes, so as to change the characteristic of side electric signal transmission, root
According to the change of electric signal transmission characteristic, it can be determined that water level.
The most basic content of above-said current signal is the directly obtainable content such as electric current, voltage.Can also be other letters
Number.
In a kind of preferable complete embodiment.Sensor has two layers of screw thread, respectively upper external screw thread 3 and lower external screw thread
4, when sensor screws in the filter of (being screwed into) bavin, first upper external screw thread 3 is screwed into, in then descending external screw thread 4 to be threaded into, tightened
Afterwards, sealed by the sealing gasket in sensor.When discharging water, when unscrewing sensor, lower external screw thread 4 can progressively disengage, instantly outer spiral shell
When line 4 completely disengages bavin filter, due to there is the presence of external screw thread 3 on upper end, sensor is filtered without departing from bavin.Prevent sensor from falling
Under.And the column 2 among two layers of screw thread does not have screw thread, referred to herein as smooth bar part.When upper external screw thread 3 departs from bavin filter, due to
The presence of middle smooth bar part, sensor upper and lower can be moved freely again.Only when continuing to turn sensor, upper external screw thread 3
After departing from from bavin filter, whole sensor can just completely disengage bavin filter.The structure of this Double-layer threaded can guarantee that sensor will not be by
Back out by mistake, or easily depart from bavin filter.
The column 2 of this sensor is hollow structure, and hollow structure is located at the centre of column 2, and size is big, can exclude more miscellaneous
Matter, avoid impurity from blocking drain tank, cause water not discharge.During draining, the ponding of bavin filter enters at upper shed 5, from below
Under shed 6 in efferent tract shell 1, the external world is being discharged to by the discharge outlet 11 of shell 1.
It is located at by going out under shed 6 above sealing gasket, when sensor is tightened in bavin filter, because the sealing of sealing gasket is made
With, can guarantee that bavin filter in oil will not flow out.
Construction, feature and the action effect of the present invention, above institute is described in detail according to the embodiment shown in schema above
Only presently preferred embodiments of the present invention is stated, but the present invention is not to limit practical range shown in drawing, it is every according to structure of the invention
Want made change, or be revised as the equivalent embodiment of equivalent variations, when still without departing from specification and illustrating covered spirit,
All should be within the scope of the present invention.
