Abstract
The utility model discloses an air pressure inflating intelligent water meter controller shell which is provided with an air pressure fully sealed structure. The controller shell is further provided with an air filling hole and an air filling plug hermetically connected with the air filling hole. The air pressure inflating intelligent water meter controller shell has the characteristics of good waterproof and moistureproof effect, convenience in maintenance, convenience in installation and the like.
Description
Technical field
The utility model relates to a kind of Intelligent water meter controller housing of inflatable pressure.
Background technology
IC-card intellectual water meter kind is more, install and use environment different, there are a lot of installation environments moister, even have by the possibility of water logging, for this reason, just very high to waterproof, the protection against the tide requirement of intellectual water meter electronic control part (controller), the waterproof of existing product majority, the moistureproof processing are: reducing gear seals separately, wiring board adopts the method for encapsulating to seal in a transparency cover power, and radio-frequency coil also independent encapsulating seals in a plastic stent, and the middle wire and plug that adopts connects.When being the wiring board encapsulating, the drawback of this method can seal into a little air, can be sometimes cold and sometimes hot during wiring board work, and cause air to expand with heat and contract with cold inside, glue is separated with transparent tegmental wall, cause seal failure; Waterproof, protection against the tide can't be accomplished in the middle plug junction of electric wire, and therefore, the water meter that uses under wet environment for a long time is easy to partly intake because of controller and damages.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of Intelligent water meter controller housing of inflatable pressure, and it has, and waterproof moisture-proof effect is good, easy access, the characteristics such as easy for installation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: this controller housing is provided with the air pressure all-sealed structure, the gas injection stopple that also is provided with injecting hole and is tightly connected with this injecting hole on controller housing.
The utility model further improves and is: injecting hole is positioned on the battery case lid of controller housing side; The gas injection stopple adopts rubber column.
The beneficial effect that adopts technique scheme to produce is: this controller housing is provided with the air pressure all-sealed structure, the gas injection stopple that also is provided with injecting hole and is tightly connected with this injecting hole on controller housing, this kind structure can be injected by injecting hole the inert gas of certain pressure, and fill in the row sealing with injecting hole, so that controller housing inside maintains the inert gas of certain pressure, the damp G﹠W of outside can not enter controller housing inside, and controller circuit element can not be corroded and oxidation under the protection of inert gas; Injecting hole is positioned on the battery case lid of controller housing side, is convenient to the sealing of injecting hole and gas injection stopple is carried out maintenance and inspection; This Intelligent water meter controller housing has good waterproof, protection against the tide, anticorrosion ability, adapts to the abominable installation environment that water meter often runs into, and has extended the serviceable life of controller.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 uses IC-card intellectual water meter structural representation of the present utility model.
In the accompanying drawings: 1, controller housing; 2, " O " RunddichtringO; 3, essentic-water-meter; 4, battery case; 5, battery case lid; 6, injecting hole; 7, gas injection stopple.
Embodiment
By the embodiment shown in Fig. 1-2 as can be known, this controller housing 1 is provided with the air pressure all-sealed structure, faying face between each several part all is tightly connected by " O " RunddichtringO, its inside can keep being not less than 0.05MP air pressure, the gas injection stopple 7 that also is provided with injecting hole 6 and is tightly connected with this injecting hole 6 on controller housing 1, can be to controller housing 1 inert gas injecting of air pressure all-sealed structure by injecting hole 6, and seal by gas injection stopple 7 and keep its air pressure inside.
Injecting hole 6 is positioned on the battery case lid 5 of controller housing 1 side; Therefore injecting hole 6 is positioned at the side, is convenient to controller housing 1 is inflated, and because its battery cover can disassemble, can be conveniently the sealing state of injecting hole 6 and gas injection stopple 7 be checked.
Using method:
when the water meter environment for use is comparatively abominable, need to increase the performance of its anticorrosive oxidation, can inject by injecting hole the inert gas of 0.02MP-0.03MP pressure to controller housing, and seal with gas injection stopple jam-pack, so that the inert gas of controller housing inside maintains certain pressure, to prevent the moisture of outside, corrosive gas or water enter controller housing inside makes it be subject to oxidation and corrosion, controller circuit element can not be corroded and oxidation under the protection of inert gas, therefore this Intelligent water meter controller housing has good waterproof, moistureproof, anticorrosion ability, adapt to the humidity that water meter often runs into, the installation environments such as water logging, extended the serviceable life of controller.
