Abstract
The utility model provides a rotary-wing anti-backflow water meter, which comprises a meter body, a water inlet and an external water outlet and is characterized in the water meter also comprises an internal water outlet, a sphere, a stop block A and a stop block B; the internal water outlet is arranged at the internal end of the inner cavity of the external water outlet communicated with the meter body; the stop block A is arranged above the internal water outlet and connected with the water body; the stop block B is arranged at the lower end of the stop block B and corresponding to the internal water outlet; and the sphere is arranged between the stop block A and the stop block B. When the water meter is used, as water flows in the forward direction, under the action of water pressure, the sphere is flushed away from the stop block A and stopped by the stop block B, and the water flows out of the external water outlet through the clearance. When water flows in the reverse direction, the sphere is flushed toward the stop block A and pressed tightly against the internal water outlet, and prevents water from flowing backwards. The water meter with the rotary-wing anti-backflow structure is simple in structure, and convenient to use, only allows water to flow in one direction, can prevent the phenomenon that metering is inaccurate and the water meter is damaged due to water backflow, and ensures the safety of water supply.
Description
Technical field
The utility model relates to instrument field, relates in particular to a kind of water meter.
Background technology
Water meter is the common tool of water measurement amount, and the principle of work of existing water meter is: current enter water meter impact impeller from the water inlet of water meter, and wheel rotation also passes to counter, by counter records user water consumption.Under the prerequisite of correctly installing and using, water meter can play the effect of accurate-metering, if the user uses the water meter upside-down mounting, under the impact of current, impeller will reverse, and drives counter and count down, cause measure wrong.
Summary of the invention
In order to address the above problem, the utility model provides a kind of rotary wing type anti-back flow water meter, comprise table body, water inlet, out outlet, characterized by further comprising interior water delivering orifice, spheroid, block A, block B, described interior water delivering orifice is arranged on inner chamber inner end, out outlet and table body connectivity part, described block A is arranged on interior water delivering orifice top and is connected with the table body, and described block B arranges table body lower end and corresponding with interior water delivering orifice, and described spheroid is arranged between block A and the block B.
The beneficial effects of the utility model are: when the utility model used, when the water forward flow, under the effect of hydraulic pressure, spheroid was rushed from block A and by block B and is blocked, and water flows out the out outlet by the gap.When the water reversed flow, spheroid is rushed at block A and is pressed on the interior water delivering orifice, has prevented the water body refluence.The utility model is simple in structure, and is easy to use, only allows water body to flow to a direction, can prevent from guaranteeing water supply security because the metering that the water body refluence causes is inaccurate and the generation of damage water meter phenomenon.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained, such as Fig. 1, water delivering orifice, 5-block A, 6-spheroid, 7-block B in 1-table body, 2-water inlet, 3-out outlet, the 4-.
As shown in Figure 1, the utility model comprises table body 1, water inlet 2, out outlet 3, interior water delivering orifice 4, spheroid 6, block A5, block B7, interior water delivering orifice 4 is arranged on inner chamber inner end, out outlet and table body 1 connectivity part, block A5 is arranged on interior water delivering orifice 4 tops and is connected with table body 1, block B7 arranges table body 1 lower end and corresponding with interior water delivering orifice 4, and spheroid 6 is arranged between block A5 and the block B7.When interior water delivering orifice 4 had current to pass through, water impact spheroid 6 moved right and is close to block B7, the water yield between the space normally flow out.When water body flow backwards, the water yield was impacted spheroid 6 and is moved to the left and is close to block A5, thereby makes spheroid 6 block interior water delivering orifice 4, has prevented the water body refluence.The utility model is simple in structure, and is easy to use, only allows water body to flow to a direction, can prevent from guaranteeing water supply security because the metering that the water body refluence causes is inaccurate and the generation of damage water meter phenomenon.
Above an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
