Abstract
The utility model discloses a sealing structure of an intelligent water meter, which comprises a water meter shell and a water meter circuit board. Transparent sealing adhesive is filled in a space between the water meter shell and the water meter circuit board and is organosilicon gel or polyurethanes transparent sealing adhesive with light transmittance higher than 92%. As the organosilicon gel or polyurethanes transparent sealing adhesive has fine chemical stability, insulation property, damp proofing, shock absorption, weather fastness and proper viscosity, the sealing structure has excellent sealing effect, the purpose of dustproof and moisture-proof sealing of the water meter circuit board is achieved really, and reliability of the intelligent water meter is guaranteed. As the light transmittance of the organosilicon gel or polyurethanes transparent sealing adhesive is higher than 92%, visibility of liquid crystal on the water meter circuit board sealed in the organosilicon gel or polyurethanes transparent sealing adhesive cannot be affected.
Description
Technical field
The utility model relates to a kind of intellectual water meter hermetically-sealed construction.
Background technology
The hermetically-sealed construction of existing intellectual water meter is to form a seal cavity between watermeter shell and water meter circuit board, the water meter circuit board is fixed in the sealing space by bearing, yet this hermetically-sealed construction of water meter, have the following disadvantages: (1) water meter circuit board air direct and in the seal cavity contacts, and contain steam and dust in the sealing space, of a specified duration when temperature variation and time one, steam in the seal cavity and dust certainly will impact serviceable life of water meter circuit board and function etc.; (2),,, thereby directly influence the running of this water meter with direct eroding water watch circuit plate in case there is steam to enter shell if the sealing of watermeter shell and O-ring seal thereof does not reach requirement; (3) tenure of use one of water meter of a specified duration, damaging appears in watermeter shell unavoidably, the slit also appears in cooperation between watermeter shell and the O-ring seal unavoidably, as untimely processing, in a single day moisture enter watermeter shell, and the water meter circuit board will make moist and lose efficacy, thereby directly influence the serviceable life of water meter.At the deficiency of above-mentioned existing water meter hermetically-sealed construction, a kind of new water meter hermetically-sealed construction needs to be resolved hurrily.
The utility model content
The intellectual water meter hermetically-sealed construction that the purpose of this utility model is to provide the reliable dust and moisture of a kind of energy, guarantees the intellectual water meter reliability.
This intellectual water meter hermetically-sealed construction that the utility model provides comprises watermeter shell, water meter circuit board, and being full of in the space between watermeter shell 1 and water meter circuit board 2 has transparent sealing glue 3.
Described transparent sealing glue adopts transmittance to surpass 92% silicon gel class or polyurethanes transparent sealing glue.
The utility model has transmittance to surpass 92% silicon gel class or polyurethanes transparent sealing glue owing to being full of in the space between watermeter shell and water meter circuit board, make and the utlity model has extraordinary sealing effectiveness, even watermeter shell the slit occurred having occurred between damage or watermeter shell and the O-ring seal to cause entering of steam and dust, steam that enters and dust do not reach the water meter circuit board at all yet, thereby can not have any impact to the water meter circuit board, make the water meter circuit board really reach the sealing purpose of dust and moisture, thereby guaranteed the reliability of intellectual water meter.And because the transmittance of silicon gel class or polyurethanes transparent sealing glue surpasses 92%, thereby can not influence the visuality that is sealed in the liquid crystal on the interior water meter circuit board by it, and silicon gel class or polyurethanes transparent sealing glue surface have hydrophobic nature, prevented effectively that also liquid crystal surfactant from producing the phenomenon of condensation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Fig. 1 is a structural representation of the present utility model, as shown in the figure, be full of in the space between watermeter shell 1 and water meter circuit board 2 transparent sealing glue 3 is arranged, liquid crystal 4, circuit board mainboard and circuit board extension line on the water meter circuit board all are sealed in the described transparent sealing glue, and wherein transparent sealing glue is to adopt transmittance to surpass 92% silicon gel class or polyurethanes transparent sealing glue.
Because silicon gel class or polyurethanes transparent sealing glue have good chemical stability and insulation thereof, moistureproof, shockproof, weatherability, moderate viscosity, make and the utlity model has extraordinary sealing effectiveness, even watermeter shell the slit occurred having occurred between damage or watermeter shell and the O-ring seal to cause entering of steam and dust, steam that enters and dust do not reach the water meter circuit board at all yet, thereby can not have any impact to the water meter circuit board, make the water meter circuit board really reach the sealing purpose of dust and moisture, thereby guaranteed the reliability of intellectual water meter.And because the transmittance of silicon gel class or polyurethanes transparent sealing glue surpasses 92%, thereby can not influence the visuality that is sealed in the liquid crystal on the interior water meter circuit board by it, and silicon gel class or polyurethanes transparent sealing glue surface have hydrophobic nature, prevented effectively that also liquid crystal surfactant from producing the phenomenon of condensation.
Claims (2)
1. an intellectual water meter hermetically-sealed construction comprises watermeter shell, water meter circuit board, and it is characterized in that being full of in the space between watermeter shell (1) and water meter circuit board (2) has transparent sealing glue (3).
2. intellectual water meter hermetically-sealed construction according to claim 1 is characterized in that described transparent sealing glue adopts transmittance to surpass 92% silicon gel class or polyurethanes transparent sealing glue.
