Abstract
The utility model relates to a water gauge water -proof type controller in pit, including casing, circuit board, trigger switch, trigger switch coil, display screen and cable, the casing includes end box and upper cover, and circuit board, trigger switch, trigger switch coil are installed in the casing, circuit board connection cable, and upper cover installation display screen, trigger switch, circuit board, display screen are the electricity and connect its characterized in that: end box internal surface system have circuit board lower seal shell, the circuit board inlays this circuit board lower seal shell of packing into to the sealed cap of seal installation circuit board on this circuit board lower seal shell. This water gauge water -proof type controller in pit, structural design scientific and reasonable can prevent effectively that external steam from permeating to the circuit board to good guarantee the dampproof and waterproof effect of internal circuit board.
Description
Technical field
This utility model belongs to water meter field, particularly a kind of down-hole water meter water-proof type controller.
Background technology
Downhole radio-frequency card intellectual water meter is applied to industrial and commercial enterprises, installs and uses in government departments and institutions and resident's missile silo
Cold water measures and automatically controls.Downhole radio-frequency card intellectual water meter is made up of water meter, control valve, gauge outfit controller.Gauge outfit controller
Control valve top can be fixedly mounted on, or installation is connected by lead.Gauge outfit controller due to needing long period of soaking in water,
Therefore must be sealed using certain means.Existing sealing means are mostly that the shell of gauge outfit controller is carried out encapsulating is close
Envelope, and circuit board is coated with protective paint, reduce the soaked impact to circuit.But, existing gauge outfit controller is formed with one layer outward
Shell.After it is soaked in water for a long time, easily there is leak in it, and steam directly can penetrate into hull outside, enters into circuit board
On, cause the damage of circuit board.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of existing counting, provides a kind of down-hole water meter water-proof type controller,
It can effectively prevent the steam in the external world from penetrating into circuit board, thus the good moistureproof and waterproof effect having ensured internal circuit board.
This utility model is solved its enumeration problem and is realized by following count protocol：
A kind of down-hole water meter water-proof type controller, including housing, circuit board, trigger switch, trigger switch coil, display screen
And cable, housing includes back box and Shang Gai, and circuit board, trigger switch, trigger switch coil are installed in housing, and circuit board connects
Cable, upper lid installs display screen, trigger switch, circuit board, display screen be electrical connection it is characterised in that：Table in described back box
Face is formed with capsul under circuit board, and circuit board is embedded in capsul under this circuit board, and seals on capsul under this circuit board
Mounting circuit boards seal cap.
And, adopt silica gel sealing between capsul and circuit board sealing cap under described circuit board.Described control
Silica gel sealing is adopted between the back box of device and upper lid.
Advantage of the present utility model and having the beneficial effect that：
This down-hole water meter water-proof type controller, is internally provided with circuit board capsul control shell, circuit board seals
Mounting circuit boards in shell, all carry out protective treatment to circuit board, capsul and controller housing, form the waterproof construction of multilamellar；
Due to forming insulating space between the circuit board capsul of internal layer and shell, internal layer containment vessel is not steeped in water, is not contacted with water,
Do not allow fragile, seepage will not occur, thus can effectively prevent the steam in the external world from penetrating into circuit board, thus good guarantee
The moistureproof and waterproof effect of internal circuit board.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, and following examples are descriptive, is not to limit
Property it is impossible to protection domain of the present utility model is limited with this.
A kind of down-hole water meter water-proof type controller, including housing, circuit board 7, trigger switch 11, trigger switch coil 9, shows
Display screen 4 and cable, housing includes back box 5 and upper lid 2, and back box 5 and upper lid 2 pass through the made screw hole 3 in its periphery and connect.Circuit
Plate, trigger switch, trigger switch coil are installed in housing, circuit board connection cables, upper lid installation display screen, trigger switch,
Circuit board, display screen are electrical connection.Its innovation is：Back box inner surface is formed with capsul 6 under circuit board, circuit board be embedded in into
Sealing mounting circuit boards sealing cap 12 on capsul under this circuit board, and capsul under this circuit board.Back box inner surface system
There are trigger switch mounting groove 10, trigger switch coil mounting groove 8.Trigger switch, trigger switch are installed in trigger switch mounting groove
For tongue tube.Trigger switch coil is installed in trigger switch coil mounting groove.Trigger switch and coil are also adopted by silica gel and carry out beating
Glue seals.Silica gel sealing is adopted between capsul and circuit board sealing cap under circuit board.Silica gel sealing is adopted outside circuit board.Control
It is also adopted by silica gel sealing between the back box of device processed and upper lid.The cable that circuit board connects portals through the made cable of back box and upper lid
Draw.
Back box top is formed with and mounts suspension hook 1.For controller is mounted in the borehole wall.
Due to forming insulating space between the circuit board capsul of internal layer and shell, internal layer containment vessel does not steep in water, no
Contact with water it is not easy to damage, seepage will not occur, thus can effectively prevent the steam in the external world from penetrating into circuit board, thus good
The good moistureproof and waterproof effect having ensured internal circuit board.
Although disclosed embodiment of the present utility model and accompanying drawing for the purpose of illustration, the counting personnel of this area are permissible
Understand, without departing from this utility model and spirit and scope of the appended claims, various replacements, to change and modifications be all can
Can, scope therefore of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
