Abstract
The utility model discloses a waterproof intelligent water meter, and a threaded gland and a sealing box which uses lead wire sealed mode are adopted, thereby the reliable sealing of a water meter circuit box is realized under the conditions of simple structure and convenient use, and the complete waterproof sealing effect (IP68 prevention grade) of the waterproof intelligent water meter during the processes of repeated disassembly and long-time use can be achieved. The structure of the waterproof intelligent water meter is that the waterproof intelligent water meter comprises a water meter, wherein a sealing box casing is fixed on the lateral surface of the water meter, the sealing box casing is hermetically connected with a threaded sealing cover, an external housing is arranged on the outer side of the threaded sealing cover, a circuit board is positioned in the sealing box casing, and the lead wire of the circuit board protrudes out of the sealing box casing through a sealing device.
Description
Technical field
The utility model relates to a kind of intellectual water meter, relates in particular to a kind of water proof type intellectual water meter that has the water-tight box.
Background technology
Present intellectual water meter is not taked special seal approach mostly, causes electronic circuit in the intellectual water meter circuit board box to be subjected to the influence of humid air and damages.For this reason, the intellectual water meter that has has been taked some moisture preventive measures, for example the mode in 99257315.3 and 200420024796.6 patents.But these designs have mostly adopted the general mode that compresses and a plurality of screw to tighten the mode of capping, its shortcoming is: reliable compaction measure or a plurality of screw firmly are difficult in tightening process evenly owing to not having, degree of tightness is difficult to reasons such as synchronous, under conditions such as cold and hot variation, material aging, modification will take place in box body structure, finally not only can lose waterproof action, even dampproof effect has not reached yet.Because the application scenario of present intellectual water meter, having much is in following table pond, ground, and the accident of being flooded damage under the rainy day or the situation of leaking often takes place.Therefore, designing a kind of degree of protection, to reach the water proof type intellectual water meter of IP68 necessary.
Summary of the invention:
The purpose of this utility model is exactly in order to address the above problem, a kind of seal box that adopts union (screwed)bonnet (UB and lead-in wire sealing means is provided, simple in structure, under the condition easy to use, realize the positiver sealing of intellectual water meter circuit box, make intellectual water meter in repeatedly dismounting and long-term use, reach the sealing effectiveness of complete waterproof (IP68 degree of protection).
To achieve these goals, the utility model has adopted following technical scheme:
A kind of water proof type intellectual water meter, it comprises water meter, is fixed with the seal box shell in the water meter side, described seal box shell and a thread sealed closure are tightly connected; The outside at thread sealed closure is provided with outer cover; Circuit board places in the seal box shell, and circuit board leads passes the seal box shell by packoff.
Be provided with O-ring seal between described thread sealed closure and seal box shell.
Described packoff is a rubber seal plug.
Described seal box shell is provided with rectangular bolt hole, and is connected with water meter by set bolt.
The seal box shell that the utility model comprises water meter, is fixed in the above, the sealing-plug that passed lead-in wire is installed on the described shell, the open ports of seal box is round, cover by round thread sealed closure, between seal box open ports and thread sealed closure, O-ring seal is arranged, when the thread sealed closure rotation tightens, the compacted sealing of O-ring seal, thus, the circuit board in the seal box is by positiver sealing.Outside at thread sealed closure is protected by outer cover.On water meter, its bolt hole is rectangular to seal box by bolted, highly makes the water meter lid position that is fastened on the box body just right up and down to adjust.
The beneficial effects of the utility model are: the structure of seal box is very simple, opens seal box as long as take off outer cover during installation and maintenance with regard to rotatable thread sealed closure, and is convenient and practical, good reliability, and repeatedly dismounting does not influence its excellent sealing performance yet.
