Abstract
The utility model discloses a reverse flow prevention water meter which comprises a meter body (1), a water inlet head (2) and a water outlet head (3), and is characterized in that a plurality of frame ribs (6) and a baffle plate (7), a T-shaped piece (9) with a top spring (8) is arranged between the baffle plate (7) and the inner water outlet hole (4), and the big head end of the T-shaped piece (9) corresponds to the inner water outlet (4). When water forwards flows, the reverse flow prevention water meter overcomes the elastic force of the top spring to push the T-shaped piece, and water passes through gaps among the frame ribs and flows outside the outer water outlet hole. When water oppositely flows, the T-shaped piece is pressed on the inner water outlet by the top spring, the inner water outlet is sealed, and water can not back flow.
Description
Affiliated technical field
The utility model belongs to the flow detection instrument of water, a kind of specifically anti-backflow water meter.
Background technology
In the prior art, comparatively Chang Yong anti-backflow water meter structure is comparatively simple, and it is connected with the retaining tongue in outlet inner chamber upper end by the bearing pin activity, during the water forward flow, can push the retaining tongue open and flow out; If aqueous reflux can be blocked by the retaining tongue.The deficiency of its existence is: tongue is sagging naturally seals outlet for retaining, but it does not have pressure to outlet, poorly sealedly tightly causes the refluence that bleeds back of water easily, influences result of use.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved anti-backflow water meter is provided, and its sealing is tight, and it is effective to prevent to flow backwards.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: table body, water inlet head, Water outlet, it is characterized in that: be provided with interior water delivering orifice in Water outlet inner chamber inner end, the outer end is provided with the out outlet, on the internal chamber wall between interior water delivering orifice and the out outlet, be provided with some frame muscle and a catch, be provided with "T"-shaped that is with the top spring between catch and interior water delivering orifice, "T"-shaped stub end is corresponding with interior water delivering orifice.
The utility model is taked technique scheme, has following beneficial effect: when the utility model uses, when the water forward flow, under hydraulic action, overcome the top spring force "T"-shaped is pushed open, water can flow out the out outlet through the gap of frame muscle.When the water reversed flow, the top spring has been pressed on the interior water delivering orifice "T"-shaped, and its envelope is tight, and water can not flow backwards.Water delivering orifice in of the present utility model is owing to by "T"-shaped capping of band top spring, contact closely, and water can not flow backwards or reverse osmosis, and it is effective to prevent to flow backwards.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model Water outlet side-looking structure diagram.
Water delivering orifice, 5-out outlet, 6-frame muscle, 7-catch, 8-top spring, "T"-shaped of 9-, 10-aperture in mark among the figure: 1-table body, 2-water inlet head, 3-Water outlet, the 4-
Embodiment
By Fig. 1, shown in Figure 2, the utility model includes: table body 1, water inlet 2, Water outlet 3, water delivering orifice 4 in Water outlet 3 inner chamber inner ends are provided with, the outer end is provided with out outlet 5, on the internal chamber wall between interior water delivering orifice 4 and the out outlet 5, be provided with some frame muscle 6 and a catch 7, be provided with "T"-shaped 9 of band top spring 8 between catch 7 and interior water delivering orifice 4, "T"-shaped 9 stub end is corresponding with interior water delivering orifice 4.Catch 7 is used to block top spring 8, is provided with aperture 10 above it, is convenient to T " the little head end of shape part 9 moves within it.
Claims (2)
1. anti-backflow water meter, it includes: table body (1), water inlet head (2), Water outlet (3), it is characterized in that: be provided with interior water delivering orifice (4) in Water outlet (3) inner chamber inner end, the outer end is provided with out outlet (5), on the internal chamber wall between interior water delivering orifice (4) and out outlet (5), be provided with some frame muscle (6) and a catch (7), be provided with "T"-shaped (9) of band top spring (8) between catch (7) and interior water delivering orifice (4), the stub end of "T"-shaped (9) is corresponding with interior water delivering orifice (4).
