Abstract
The utility model relates to a magnetic differential pressure indicating alarm, which belongs to the field of alarms for oil supply filters. The magnetic differential pressure indicating alarm comprises a shell of a pressure plunger. The magnetic differential pressure indicating alarm is characterized in that one side of the shell is provided with a dial plate comprising an observation meter shell and a rotating plate, the observation meter shell is provided with a semi-circular observation window, an indicator is fixedly arranged at the center of the observation window, and the rotating plate is provided with fan-formed scales and an alarm zone. The scales is in a 90-degree arc shape, and nine partitioned marks are uniformly arranged; and the alarm zone is arranged on one anticlockwise side provided with scales in a 90-150-degree fan shape, and is provided with a red coating layer. The reading is clear after a product is improved, an arbitrary value within the range from 0 bar to 0.8 bar can be read, and thus the internal pressure difference can be well mastered.
Description
Technical field
The utility model belongs to fuel feeding filter cleaner alarm field, especially a kind of magnetic pressure reduction indication alarm.
Background technology
Existing original magnetic pressure reduction indication alarm comprises housing and dial plate; Dial plate is provided with reddish rotating disc; Plunger in the housing drives inner magnet compression spring occurrence positions and moves; The magnet of the mobile repulsion rotating disc of magnet turns clockwise rotating disc, and the red area that shows along with the increase of pressure also will constantly increase.Owing to there is not clear and definite scale to have only a general value, when its redness is filled up, be 0.8bar, adding a full half when its redness is 0.6bar, is not easy to observe.
The utility model content
According to the deficiency of above prior art, the technical matters that the utility model will solve is: a kind of rule that has is provided, indicates clear and definite magnetic pressure reduction indication alarm.
The utility model solves the technical scheme that its technical matters adopted: a kind of magnetic pressure reduction indication alarm; Comprise the housing that is provided with the pressure plunger; It is characterized in that: housing one side setting is by observing the dial plate that watchcase and rotating disc constitute; Observe watchcase the semicircle view window is set, view window central authorities fixedly install pointer, and rotating disc is provided with fan-shaped rule and caution district.
When producing pressure differential; Plunger drives inner magnet compression spring occurrence positions and moves; The magnet of the mobile repulsion rotating disc of magnet turns clockwise rotating disc, and the numerical value of the rule that aligns with the pointer arrow of view window is pressure differential; The red area that shows along with the increase of pressure also will constantly increase, can clear and definite value of indicated pressure clearly and warning.
Wherein preferred version is:
Described rule is 90 ° of circular arcs, divides equally 9 interval marking are set.From the 0-0.8bar mark, each is spaced apart 0.1bar, can read the pressure in the 0-0.8bar scope.
Described caution district is arranged on the counterclockwise side of rule, be 90 °-150 ° fan-shaped, red coatings is set.When pressure increased to 0.8bar, pointer pointed to 0.8, and half view window is filled up in red caution district, and at this moment the internal magnetization switch can be connected and send switching signal and make alarm equipment alarm, and filter core is cleaned in prompting.
The utility model magnetic pressure reduction indication beneficial effect that alarm had is: through the dial plate that is made up of observation watchcase and rotating disc in housing one side setting, the observation watchcase is provided with the semicircle view window, and view window central authorities fixedly install pointer; Rotating disc is provided with fan-shaped rule and caution district, and rule is 90 ° of circular arcs, divides equally 9 interval marking are set; The caution district is arranged on the counterclockwise side of rule; Be 90 °-150 ° fan-shaped, red coatings is set, improving the back product has a clear and definite reading; Can read the arbitrary value in the 0-0.8bar scope, it is poor better to grasp internal pressure.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the rotating disc of the utility model;
Wherein: 1, housing 2, dial plate 3, rotating disc 4, pointer 5, observation watchcase 6, rule 7, caution district.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
Like Fig. 1, shown in Figure 2; Be provided with the housing 1 of pressure plunger, housing 1 one side settings are observed watchcase 5 the semicircle view window are set by observing watchcase 5 and the dial plate 2 that rotating disc 3 constitutes; View window central authorities fixedly install pointer 4, and rotating disc 3 is provided with fan-shaped rule 6 and caution district 7.
Rule 6 is 90 ° of circular arcs, divides equally 9 interval marking are set.From the 0-0.8bar mark, each is spaced apart 0.1bar, can read the pressure in the 0-0.8bar scope.
Caution district 7 is arranged on rule 6 counterclockwise sides, be 90 °-150 ° fan-shaped, red coatings is set.
Principle of work and use:
When producing pressure differential, plunger drives inner magnet compression spring occurrence positions and moves the magnet of the mobile repulsion rotating disc 3 of magnet; Rotating disc 3 is turned clockwise; The numerical value of the rule 6 that aligns with pointer 4 arrows of view window is pressure differential, and the red area that shows along with the increase of pressure also will constantly increase, when pressure increases to 0.8bar; Pointer points to 0.8; Half view window is filled up in red caution district 7, and at this moment the internal magnetization switch can be connected and send switching signal and make alarm equipment alarm, and filter core is cleaned in prompting.
