Abstract
The utility model discloses an anti-backflow water meter, which comprise a meter body (1), a water inlet head (2) and a water outlet head (3), and is characterized in that in an internal water outlet (4) and an external water outlet (5) are formed in an inner chamber of the water outlet head (3); an inverted T-shaped part (7) with a top spring (8) is arranged above the internal water outlet (4), the small end of the inverted T-shaped part (7) is positioned in a sleeve (8), and a mesopore (9) is formed in the inverted T-shaped part (7). By adopting the anti-backflow water meter, when water flows in the positive direction, the inverted T-shaped part is pushed open by overcoming the elasticity of the top spring, and then the water flows out through the external water outlet. When water flows in the negative direction, the inverted T-shaped part is pressed on the internal water outlet and is tightly sealed, therefore the water can not flow back. Since the internal water outlet in the utility model is covered by the inverted T-shaped part with the top spring, the contact is tight, and the anti-backflow effect is good.
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, establish the table body cavity in the table body, it is characterized in that: be provided with in Water outlet inner chamber inner end and show the interior water delivering orifice that upwardly opens that body cavity is communicated with, the outer end is provided with the out outlet of opening to the side, be provided with inverse-T-shaped that is with the top spring above interior water delivering orifice, inverse-T-shaped stub end is corresponding with interior water delivering orifice, and its little head end is arranged in sleeve.
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 inverse-T-shaped is pushed open, water can flow out the out outlet.When the water reversed flow, the top spring has been pressed on the interior water delivering orifice inverse-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 inverse-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.
Water delivering orifice, 5-out outlet, 6-top spring, inverse-T-shaped of 7-, 8-sleeve, 9-mesopore, 10-show body cavity in mark among the figure: 1-table body, 2-water inlet head, 3-Water outlet, the 4-
Embodiment
By shown in Figure 1, the utility model includes: table body 1, water inlet 2, Water outlet 3, establish table body cavity 10 in the table body 1, be provided with in Water outlet 3 inner chamber inner ends and show the interior water delivering orifice 4 that upwardly opens that body cavity 10 is communicated with, the outer end is provided with the out outlet 5 of opening to the side, be provided with inverse-T-shaped 7 of band top spring 6 above interior water delivering orifice 4, inverse-T-shaped 7 stub end is corresponding with interior water delivering orifice 4, and its little head end is arranged in sleeve 8.Sleeve 8 is equivalent to inverse-T-shaped 7 moving guide rail.
The utility model be prevent too much water enter sleeve 8 upper ends hinder inverse-T-shaped 7 on move, establish mesopore 9 in inverse-T-shaped 7, mesopore 9 has a plurality of water exports inverse-T-shaped 7 upper end open in its following side.Like this, water can flow out from mesopore after entering sleeve 8 upper end cavitys.
Claims (2)
1. anti-backflow water meter, include: table body (1), water inlet head (2), Water outlet (3), establish table body cavity (10) in the table body (1), it is characterized in that: be provided with in Water outlet (3) inner chamber inner end and show the interior water delivering orifice (4) that upwardly opens that body cavity (10) is communicated with, the outer end is provided with the out outlet (5) of opening to the side, be provided with inverse-T-shaped (7) of band top spring (6) in interior water delivering orifice (4) top, the stub end of inverse-T-shaped (7) is corresponding with interior water delivering orifice (4), and its little head end is arranged in sleeve (8).
2. a kind of anti-backflow water meter according to claim 1 is characterized in that: establish mesopore (9) in inverse-T-shaped (7).
