Water mist prevention instrument dial plate

Abstract

The invention discloses a water mist prevention instrument dial plate. The structure of the water mist prevention instrument dial plate comprises a dial plate, a fixed plate, a connecting pipe, and arotary valve, and the fixed plate is welded with the connecting pipe; the rotary valve is movably clamped with the connecting pipe; the dial plate is embedded and fixed at the upper end of the connecting pipe; when water mist is attached to the inner side of a glass sheet on the dial plate, a pointer is driven to rotate through a rotating shaft; a water absorption block on the pointer can absorb and erase water attached to the inner side of the glass sheet; and the water absorption block can be pushed to be tightly attached to the inner side of the glass sheet all the time through a supportingframe in the water absorption block. The condition of unclear reading caused by water mist attached to the inner side of the glass sheet is effectively avoided, two swing plates in a drainage mechanism are pushed from top to bottom by the drained water, so that the two swing plates can swing downwards in opposite directions, the long-term accumulation of the water absorbed by the pointer is effectively avoided, and the absorption effect of the pointer on the water mist on the inner side of the glass sheet is easily reduced.

Description

technical field [0001] The invention relates to the field of pressure instruments, in particular to a water-proof and fog-proof instrument panel. Background technique [0002] The anti-fog instrument panel can prevent the external water mist from adhering to its outer surface through the anti-fog layer on the glass sheet of the dial, so that the user cannot read the data on the instrument panel. It is a common equipment in the processing factory, based on According to the above description, the inventors found that the existing instrument panel of a waterproof fog instrument mainly has the following deficiencies, for example: [0003] Since the stone factory needs to be equipped with a high-pressure blower to blow off the lime attached to the staff, the glass sheet used for the anti-fog dial on the high-pressure blower used in the stone processing factory is easily hit by small stone flakes, causing small holes, resulting in humid air When the water mist is easy to adhere t...

[0002] The anti-fog instrument panel can prevent the external water mist from adhering to its outer surface through the anti-fog layer on the glass sheet of the dial, so that the user cannot read the data on the instrument panel. It is a common equipment in the processing factory, based on According to the above description, the inventors found that the existing instrument panel of a waterproof fog instrument mainly has the following deficiencies, for example:

[0003] Since the stone factory needs to be equipped with a high-pressure blower to blow off the lime attached to the staff, the glass sheet used for the anti-fog dial on the high-pressure blower used in the stone processing plant is easy to be hit by the small stone flakes to make small holes, resulting in humid air Water mist easily attaches to the back of the glass sheet of the waterproof fog dial through small holes, resulting in unclear readings, and it is easy to damage the internal components of the instrument dial if it stays for a long time
