Abstract
The complete antifreeze dry-type meter of one that the present invention provides, including watchcase and the metering unit that is arranged in watchcase, the bottom of this metering unit arranges a dividing plate, in order to watchcase is isolated into current chamber and install metering unit measurement chamber, dividing plate be Polodyakonov coefficient coefficient be the enhancing nylon sheet of 6-8；The bottom surface of dividing plate is provided with a soft silica gel pad or soft nontoxic rubber and plastic glue gasket.By using the nylon sheet that hardness is higher to make dividing plate, improve the metering unit resistance to the pressure produced that freezes, simultaneously, achieve watchcase volume when icing pressure extrusion by soft silica gel pad, increase watchcase volume, thus effectively avoid the destruction that water meter is caused that freezes, especially, by arranging buffer cavity in watchcase, the volume of current chamber in watchcase can be promoted to greatest extent, avoid the freezing and expansion destruction to water meter the most thoroughly.
Description
Technical field
The invention belongs to technology of instrument and meter field, specifically water meter technology, especially a kind of complete
Antifreeze dry-type meter.
Background technology
Metering unit that existing dry-type meter mainly by watchcase and is arranged in watchcase, impeller portion
Part, principal and subordinate's transmission magnet steel are constituted, and the bottom of metering unit arranges a dividing plate, will separate in watchcase
For current chamber and the chamber of installation metering unit, wheel member is arranged in current chamber, institute
After having parts installation, the space in watchcase is substantially stationary constant, i.e. its constancy of volume, this
One constant volume is for water meter measurement and installs more convenient, but when ambient temperature is less than zero
Degree Celsius time, the hydrops in watchcase easily freezes, and expands, and can produce watchcase and metering unit
Outside extruding force, occurs that watchcase is squeezed crushes often, causes water meter to damage.
The Chinese utility model patent of Patent No. 200720199333.7, by watchcase
Soft expanding material is set up in bottom surface, when hydrops freezing and expansion, extrudes this soft expanding material and makes table
The volume of shell becomes big, thus contributes to slowing down the extruding force frozen to watchcase, effectively alleviates and subtracts
Lack icing and cause rupturing of watchcase.
But, this measure, it is merely by increasing watchcase volume, does not solve watchcase originally
Body or the robustness of its interior parts, when soft expanding material is not provided that bigger volume increment
Time, the hardness strengthening watchcase and interior parts thereof is icing to be uniquely reduced or avoided make water meter
The infringement approach become.
Summary of the invention
It is an object of the invention to overcome existing dry-type meter volume to fix, there is icing and it is squeezed
Crush the problem split.
For reaching above-mentioned purpose, the invention provides a kind of complete antifreeze dry-type meter, including watchcase and
The metering unit being arranged in watchcase, the bottom of this metering unit arranges a dividing plate, in order to by table
Shell is isolated into current chamber and installs the measurement chamber of metering unit, and described dividing plate is Polodyakonov coefficient
Coefficient is the enhancing nylon sheet of 6-8；The bottom surface of dividing plate is provided with a soft silica gel pad or soft nothing
Poison rubber and plastic glue gasket.
The bottom of above-mentioned watchcase is provided with a buffer cavity, and its opening leads to described current chamber,
The embedded edge that is provided with of this opening part is arranged with the portable plate of soft silica gel sealing ring；
The underrun back-moving spring of described buffer cavity couples with described portable plate.
The invention have the advantage that by using the nylon sheet that hardness is higher to make dividing plate, improve meter
The amount parts resistance to the pressure produced that freezes, meanwhile, achieves table by soft silica gel pad
Shell volume, when icing pressure extrusion, increases watchcase volume, thus it is right effectively to avoid icing
The destruction that water meter causes, especially, by arranging buffer cavity in watchcase, can be to greatest extent
The volume of the current chamber promoted in watchcase, avoid freezing and expansion pair the most thoroughly
The destruction of water meter.
With embodiment, the present invention is elaborated below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is complete antifreeze dry-type meter watchcase sectional view.
Description of reference numerals: 1, watchcase；2, metering unit；3, dividing plate；4, current chamber；
5, measurement chamber；6, soft silica gel pad or soft nontoxic rubber and plastic glue gasket；7, buffer cavity；

Detailed description of the invention
In order to overcome existing dry-type meter volume to fix, there is icing to asking that its extruding ruptures
Topic, the complete antifreeze dry-type meter shown in a kind of Fig. 1, including watchcase 1 and be arranged in watchcase 1
Metering unit 2, the bottom of this metering unit 2 arranges a dividing plate 3, in order to by watchcase 1 every
From the measurement chamber 5 for current chamber 4 with installation metering unit 2, dividing plate 3 is Polodyakonov coefficient
Coefficient is the enhancing nylon sheet of 6-8；The bottom surface of described dividing plate 3 be provided with a soft silica gel pad or
Soft nontoxic rubber and plastic glue gasket 6.
As can be seen here, the present embodiment, by strengthening the hardness of dividing plate 3, improves metering unit pair
The resistance of freezing and expansion pressure, by arranging soft silica gel pad 6 in its bottom surface, is subject to meanwhile
Deformation during freezing and expansion extruding, increases the volume of watchcase 1, and effectively alleviating freezes produces watchcase 1
Raw extruding force, slow down the damage degree frozen to water meter, it is ensured that the safe operation of water meter.
In order to fundamentally solve the destruction causing water meter that freezes, the present embodiment is further at table
The bottom of shell 1 is provided with a buffer cavity 7, and its opening leads to described current chamber 4, this opening
Locate the embedded edge that is provided with and be arranged with the portable plate 8 of soft silica gel sealing ring；Buffer cavity 7
Underrun back-moving spring 9 couple with described portable plate 8.When freezing and expansion, portable plate 8
It is extruded and moves in buffer cavity 7, increase the volume of watchcase 1, because buffer cavity 7
Volume relatively big, therefore, it is provided that sufficiently large watchcase volume increment, thus solves thoroughly
The damage that the bulbs of pressure of water meter are caused by icing of having determined.
