Abstract
The utility model relates to an antifreezing water meter, which comprises a meter shell, wherein, a meter core is arranged inside the meter shell; a glass panel which is provided with an 'O'-shaped seal ring is arranged on the end face of the upper end of the meter shell; and the end part of the upper end of the meter shell is in threaded connection with an upper roll-over cover seat one side of which is hinged with an upper roll-over cover. The antifreezing water meter is characterized in that: an expansion buffer material is distributed on the inner wall of the meter shell and the expansion buffer material is also arranged on the inner bottom surface of the meter shell; and the expansion buffer materials are flexible silicone rubber materials or flexible nontoxic rubber-plastic materials. The antifreezing water meter is simple in structure, low in cost and convenient in assembly.
Description
Technical field:
The utility model relates to a kind of water meter, particularly relates to a kind of Anti-freezing water meter.
Background technology:
At present, known water meter is to be serially connected between the water pipe, the water of water-main flows out by water pipe and through water meter, simultaneously water meter has write down streamflow that water passes through and has represented with the mode of pointer, water meter so continues ceaselessly operate as normal, still, because the variation of weather, especially when wintry weather turns cold, when temperature drops to below the zero degrees celsius, the temperature around the water meter also drops to zero degrees celsius when following along with weather turns cold, promptly can cause the water in the water meter to build-up ice, expansion when causing water gage glass panel or water meter housing to can't stand that because of holding water build-ups ice is broken, even leak, thus, have to take the mode of cutting off the water, avoid wasting of water, like this, not only influence daily life, brought inconvenience to people simultaneously, and, also will cause the damage of water meter and increase extra maintenance cost.
Summary of the invention:
The purpose of this utility model is that a kind of improved Anti-freezing water meter will be provided, and it not only can effectively reach the damage that prevents water meter in low temperature, and, rational in infrastructure, easily manufactured.
The technical solution of the utility model is as follows to achieve the above object: a kind of Anti-freezing water meter of the present utility model has a watchcase, be provided with a watch core in the described watchcase, the upper end end face of described watchcase is provided with the face glass of band " O " RunddichtringO, the upper end end thread of described watchcase is connected with a upturning lid seat, one side hinge-coupled of described upturning lid seat has a upturning lid, be distributed with a slow material that expands on the inwall of described watchcase, also be provided with a slow material that expands on the inner bottom surface of described watchcase, the described slow material that expands is soft silicon elastomeric material or soft nontoxic rubber-plastics material.
Because the utility model has improved existing water meter; employing is being provided with the slow material that expands on the inwall of water meter housing and on the inner bottom surface; temperature around the water meter drops to zero degrees celsius when following; water in the water meter will be formed ice cube and be expanded; the power of abnormal expansion at first acts on the slow material that expands; then; the slow material that expands promptly is compressed; thus; enlarged original space; and the power of the suffered abnormal expansion of the face glass that makes the watchcase of water meter or water meter will reduce; so just avoided the watchcase of water meter or the face glass of water meter to be squeezed broken by the power of abnormal expansion; and has antifreezing effect preferably; thereby protected the watchcase of water meter and the face glass of water meter, made water meter be continued operate as normal, also prolonged the serviceable life of water meter; and stopped the influence of bringing for daily life fully, this utility model is simple in structure; cost is low; easy for installation.
Description of drawings:
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the inner structure synoptic diagram of a kind of Anti-freezing water meter of the present utility model.
Embodiment:
Describe in detail according to details and working condition below in conjunction with accompanying drawing according to a kind of Anti-freezing water meter device that the utility model proposes.
Referring to Fig. 1, a kind of Anti-freezing water meter of this utility model is made of described watchcase 1, described watch core 2, described upturning lid seat 5 and described upturning lid.
Be distributed with a described slow material 6 that expands on the inwall of described watchcase 1, also be installed on a described slow material 7 that expands on the inner bottom surface of described watchcase 1, the described slow material 6 that expands, 7 is soft silicon elastomeric material or soft nontoxic rubber-plastics material, be equipped with a described watch core 2 in the described watchcase 1, be mounted with a face glass 4 on the upper end end face of described watchcase 1, be embedded with one " O " RunddichtringO 3 on the periphery of described face glass 4, the upper end end thread of described watchcase 1 is connected with a described upturning lid seat 5, and a side hinge-coupled of described upturning lid seat 5 has a described upturning lid.
A kind of Anti-freezing water meter of the present utility model is simple in structure, and production cost is low, particularly when the water meter peripheral temperature reaches icing, still can normally use, and has reduced the spoilage of water meter effectively, has ensured normal life.
