Abstract
The complete antifreeze dry-type meter of the one that the utility model provides, comprise watchcase and be arranged on the metering unit in watchcase, the bottom of this metering unit arranges a dividing plate, in order to watchcase be isolated into current chamber and install the measurement chamber of metering unit, the enhancing nylon sheet of dividing plate to be Polodyakonov coefficient coefficient be 6-8; The bottom surface of dividing plate is provided with a soft silica gel pad or soft nontoxic rubber and plastic glue gasket.Dividing plate is made by adopting the higher nylon sheet of hardness, improve the resistibility of metering unit to the pressure of icing generation, simultaneously, achieve watchcase volume when icing pressure extrusion by soft silica gel pad, increase watchcase volume, thus effectively avoid the destruction of freezing and water meter being caused, especially, by arranging buffering cavity in watchcase, the volume of the current chamber in watchcase can be promoted to greatest extent, fundamentally avoiding the destruction of freezing and expansion to water meter thoroughly.
Description
Technical field
The utility model belongs to technology of instrument and meter field, specifically water meter technology, especially a kind of complete antifreeze dry-type meter.
Background technology
Existing dry-type meter is primarily of watchcase and the metering unit that is arranged in watchcase, wheel member, principal and subordinate's transmission magnet steel is formed, the bottom of metering unit arranges a dividing plate, the chamber of current chamber and installation metering unit will be divided in watchcase, wheel member is arranged in current chamber, after all parts installations, space in watchcase immobilizes substantially, its constancy of volume i.e., this constant volume is for water meter measurement and install more convenient, but when ambient temperature is lower than zero degrees celsius, ponding in watchcase easily freezes, expand, outside extruding force can be produced to watchcase and metering unit, often occur that watchcase is squeezed crushes, water meter is caused to damage.
The patent No. is the Chinese utility model patent of 200720199333.7, by setting up soft expanding material in the bottom surface of watchcase, when ponding freezing and expansion, extruding this soft expanding material makes the volume of watchcase become large, thus contribute to slowing down the extruding force of freezing to watchcase, effectively alleviate and decrease to freeze and cause breaking of watchcase.
But, this measure, only by increasing watchcase volume, do not solve the soundness of watchcase itself or the parts in it, when soft expanding material can not provide larger volume increment time, the hardness strengthening watchcase and interior parts thereof uniquely reduces or avoid the infringement approach caused water meter that freezes.
Utility model content
The purpose of this utility model overcomes existing dry-type meter volume to fix, and there is the problem of freezing and breaking to its extruding.
For reaching above-mentioned purpose, the utility model provides a kind of complete antifreeze dry-type meter, comprise watchcase and be arranged on the metering unit in watchcase, the bottom of this metering unit arranges a dividing plate, in order to watchcase be isolated into current chamber and install the measurement chamber of metering unit, the enhancing nylon sheet of described dividing plate to be Polodyakonov coefficient coefficient be 6-8; The bottom surface of dividing plate is provided with a soft silica gel pad or soft nontoxic rubber and plastic glue gasket.
The bottom of above-mentioned watchcase is provided with a buffering cavity, and its opening leads to described current chamber, and this opening part is embedded is provided with the portable plate that an edge is arranged with soft silica gel O-ring seal;
The underrun back-moving spring of described buffering cavity connects with described portable plate.
The utility model has the advantages that: make dividing plate by adopting the higher nylon sheet of hardness, improve the resistibility of metering unit to the pressure of icing generation, simultaneously, watchcase volume is achieved when icing pressure extrusion by soft silica gel pad, increase watchcase volume, thus effectively avoid the destruction of freezing and water meter being caused, especially, by arranging buffering cavity in watchcase, the volume of the current chamber in watchcase can be promoted to greatest extent, fundamentally avoid the destruction of freezing and expansion to water meter thoroughly.
Below in conjunction with drawings and Examples, the utility model is elaborated.
Accompanying drawing explanation
Fig. 1 is complete antifreeze dry-type meter watchcase cut-open 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, cavity is cushioned; 8, portable plate; 9, back-moving spring.
Embodiment
Fix to overcome existing dry-type meter volume, there is the problem of freezing and its extruding being broken, complete antifreeze dry-type meter shown in a kind of Fig. 1, comprise watchcase 1 and be arranged on the metering unit 2 in watchcase 1, the bottom of this metering unit 2 arranges a dividing plate 3, in order to watchcase 1 be isolated into current chamber 4 and install the measurement chamber 5 of metering unit 2, the enhancing nylon sheet of dividing plate 3 to be Polodyakonov coefficient coefficients be 6-8; The bottom surface of described dividing plate 3 is provided with a soft silica gel pad or soft nontoxic rubber and plastic glue gasket 6.
As can be seen here, the present embodiment is by strengthening the hardness of dividing plate 3, improve the resistibility of metering unit to freezing and expansion pressure, meanwhile, by arranging soft silica gel pad 6 in its bottom surface, deformation when extruding by freezing and expansion, increase the volume of watchcase 1, effective alleviation is frozen to the extruding force of watchcase 1 generation, slow down the damage degree frozen to water meter, ensure that the safe operation of water meter.
In order to fundamentally solve the destruction of freezing and causing water meter, the present embodiment is provided with a buffering cavity 7 in the bottom of watchcase 1 further, its opening leads to described current chamber 4, and this opening part is embedded is provided with the portable plate 8 that an edge is arranged with soft silica gel O-ring seal; The underrun back-moving spring 9 of buffering cavity 7 connects with described portable plate 8.When freezing and expansion, portable plate 8 is extruded and moves in buffering cavity 7, increases the volume of watchcase 1, because the volume of buffering cavity 7 is larger, therefore, it can provide enough large watchcase volume increment, thus solves the damage of freezing and causing the swelling pressure of water meter thoroughly.
