Description
Technical Field
The utility model relates to a water gauge technical field especially relates to a novel bad water gauge of freezing protection.
Background
The water meter is a meter for measuring water flow, mostly for measuring the accumulated flow of water, and generally divided into a positive displacement water meter and a speed water meter, which originate from the united kingdom, the development of the water meter has a history of nearly two hundred years, when selecting the specification of the water meter, the size and the flow range of the used flow under the normal condition should be estimated first, and then the water meter with the specification of which the common flow is closest to the value is selected as the first choice.
At present, the anti-freezing of a water pipe and a water meter in the north is a problem which needs to be considered in winter in the north, and normal domestic water can be greatly influenced because the water pipe and the water meter are easy to freeze and are continuously unchanged for many days after being frozen. Because the continuous improvement of anti-freezing measures, the main water pipe that each arrives at home in the north all can adopt modes such as wrapping up in the heat preservation and carry out the water pipe heat preservation, and main water pipe can not be frozen winter, but if the water gauge of connecting the main water pipe at home does not set up anti-freezing measures, leads to the water gauge to freeze very easily, and the anti-freezing mode that most adopts to this problem in the north at present does, wraps up the one deck with objects such as cotton-flax fabric, plastics, foam. The function of heat preservation of the outdoor water pipe is achieved. And in winter, the water pipe is not frozen without closing doors and windows, and the water pipe is still frozen if the balcony, the kitchen, the bathroom and all doors and windows facing north are not closed tightly at night to ensure the indoor mild temperature. In the winter water pipe anti-freezing method III, the temperature of the dripping anti-freezing water is low in the flowing process, and the dripping anti-freezing water cannot freeze, so that the water faucet can be slightly unscrewed at night in the areas with the weather below five ℃ in winter, water flows in a line, and the water cannot freeze. The winter water pipe anti-freezing method is four, and the electric tracing heat preservation bag which is popular at present for water pipe heat transfer is used in a solar water heater more, but is also feasible for heat preservation and heating of pipelines, but the price is a little bit expensive. Of course, hot towel application and hot water spraying pipeline application are also possible.
However, these methods all require manual anti-freezing, when the temperature is rapidly reduced or anti-freezing measures are not performed in place, the risk of freezing the water meter is extremely high, and the water flow can be ensured to be smooth only by adopting heating measures.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention provides a novel icing damage-proof water meter, when the inside of the water meter body is frozen by the influence of the outside temperature, the inside of the whole water meter body will expand, because the density of water is large, the density of ice is small, the intermolecular space becomes large after freezing, and the total mass is not changed, so the volume will become large, at this time, the inside of the water meter receives a certain pressure or thrust generated by expansion, the middle sleeve of the gear box is pushed upwards, so that the spring between the cover plate of the gear box and the middle sleeve of the gear box is compressed, so the volume inside the water meter will become large, so that the water has enough volume to expand after becoming ice, thereby avoiding the burst of the water meter due to freezing, making the water meter unable to measure, and when the ice melts, the spring pushes back the middle sleeve of the gear box to the original position through elasticity, thereby ensuring the normal measurement of the water meter, the movement of the sleeve in the gear box is controlled through the elastic deformation of the spring, so that external force is eliminated, and the effect of protecting the movement from being damaged is achieved. The utility model discloses the practicality is strong.
The utility model discloses an above-mentioned technical problem is solved to following technical means:
the utility model discloses a novel bad water gauge of freezing loss prevention includes the water gauge body, the both ends of water gauge body are equipped with water inlet and delivery port respectively, the inside of water gauge body is equipped with the gear assembly that is used for measuring discharge, the gear assembly is installed through scarf joint into the gear box in the cover the water gauge is originally internal, the top of cover slides and is equipped with the gear box apron in the gear box, the gear box apron with the even butt in interval is equipped with a plurality of springs between the cover in the gear box, the top card of cover is equipped with the gear box overcoat in the gear box, the below butt of cover has airtight backing plate in the gear box, the below pad of airtight backing plate has the rubber circle.
Furthermore, the top surface of the gear box outer sleeve is provided with a dial indicator, and the dial indicator is connected with the gear assembly through a connecting rod.
Further, an opening is formed in the airtight backing plate, when the lower end of the gear assembly is installed in the water meter body, the lower end of the gear assembly penetrates through the airtight backing plate and extends into the water meter body to be contacted with water flow.
Further, the rubber ring adopts a latex silica gel rubber gasket.
Further, when the gear box outer sleeve is installed, the gear box middle sleeve and the gear box cover plate are inserted into the gear box outer sleeve in an embedded mode.
The utility model has the advantages that: when the inside of the water meter body is frozen under the influence of the outside air temperature, the inside of the whole water meter body can expand, because the density of water is high, the density of ice is low, the intermolecular gap becomes large after freezing, and the total mass is not changed, so the volume will be enlarged, at this time, the inner part of the water meter is pushed upwards by the thrust generated by certain pressure or expansion, thereby the spring between the gear box cover plate and the gear box middle sleeve is compressed, the volume inside the water meter is enlarged, the water has enough volume to expand after becoming ice, thereby preventing the water meter from bursting due to freezing, preventing the water meter from being incapable of metering, and after the ice melts, the spring pushes the gear box middle sleeve back to the original position through elasticity, thereby guaranteed the normal measurement of water gauge, controlled the removal of cover in the gear box through the elastic deformation of spring to external force has been eliminated, has played a protection core and has not destroyed the effect. The utility model discloses the practicality is strong.
