Abstract
The utility model relates to a water filtering net of water meter, comprising a case, a water inlet cover, a float, a locating post, etc. The circumferential surface of the top of the case is provided with an upper water inlet hole and the water inlet cover is provided with a lower water inlet hole. When the pipeline is in the normal water feeding state, the water enters from the lower water inlet hole of the water inlet cover and the float is pushed away, and then the water flows into the water inlet hole of the impeller case and the impeller is impacted to count. When the pipeline has water leakage, the hydraulic pressure can not drive the float, and then the water can only enter from the upper water inlet hole of the case and the inclined hole positioned at the corresponding position of the impeller case, and the impeller is impacted count. Because the upper water inlet hole is small and the water inlet pressure is large, the impeller can be impacted to rotate to count even a drip of water enters and then the sensitivity of drip proof is greatly enhanced. The water filtering net can also be assembled with the common meter case and is provided with preferable interchangeability.
Description
Technical field
The utility model relates to the water meter water strainer.
Background technology
Water meter is the higher water metering instrument of accuracy requirement, in order to ensure metering accurately, must prevent that impurity is encroached on it in the sealing, so below the water meter turbine box, water strainer is installed, water strainer is provided with the inlet opening, make on the one hand into water impact impeller water meter counting foundation is provided, make again on the other hand outside impurity is blocked in the water, can not cause the water meter internal contamination is blocked.The existing water meter water strainer inlet opening that on whole faces of cylinder of case and bottom surface, all distributing, water intake velocity is very fast, directly impacts the impeller counting, when tap is opened very for a short time, when only weeping occurring on the pipeline, water meter just can't be counted, sensitivity is very low, cannot antidrip.A kind of drip-proof water strainer was once arranged, need to use little water inlet tube, water quality inferiority is easily blocked aperture, also can't be equipped with common watchcase, and interchangeability is low.
Summary of the invention
Technical problem to be solved in the utility model all provide in the defective that overcomes prior art a kind of highly sensitive, can be equipped with common watchcase, water meter water strainer that interchangeability is high.
Embodiment of the present utility model is:
It comprises case, and case is provided with the inlet opening, it is characterized in that described case bottom is provided with into water cover, last inlet opening is located on the periphery at case top, following inlet opening is located at on the water cover, is provided with reference column in the water inlet cover, and float is sleeved on the reference column and is fitted on the case inner bottom surface.
Described water inlet cover is the hollow cone bodily form, and the following inlet opening on it is distributed on circular conical surface and the bottom surface.
Also be provided with compressing tablet in the described float.
Press the water strainer of the utility model design, improved water inlet structure, normal water inlet is entered by the following inlet opening on the water inlet cover, when tap is opened very for a short time or pipeline when producing weeping, enter by last inlet opening, be distributed on the periphery at case top and go up the inlet opening, the corresponding less inclined hole of offering in the impeller box side is because the aperture is less, hydraulic pressure is bigger, even water inlet little by little, also can be impacted the impeller rotation and produce counting, and drip-proof sensitivity is improved greatly; This water strainer also can be equipped with common watchcase simultaneously, and interchangeability is higher.
Description of drawings
Fig. 1 is the utility model sectional structure synoptic diagram;
Fig. 2 is the utility model contour structures synoptic diagram.
Embodiment
In conjunction with above-mentioned accompanying drawing embodiment the utility model is described in detail again:
Shown in Fig. 1-2, the case 1 of water meter water strainer is hat, and its upper edge close-fitting is on the omoplate face of impeller box (not shown), and its effect one is a water into, impacts the impeller counting, and the 2nd, impurity enters in the anti-sealing.Inlet opening 4 is distributed on the top circumference face on the case, and the corresponding inclined hole position on the impeller box all can be aimed in arbitrary inlet opening, and the water that is entered by inclined hole just in time impacts on the impeller (not shown), makes the impeller rotation produce counting.Be provided with the water inlet cover 6 of the hollow cone shape of downward extension in case bottom, following inlet opening 7 is located on the circular conical surface and bottom surface of water cover into.In water inlet cover 6, be provided with close-fitting and bonding reference column 3, this reference column top can be inserted in the aperture of impeller box bottom, making the water strainer installing and locating uses, and be fitted on the case inner bottom surface at the one discoidal float 2 of suit on this reference column, on float, also be provided with simultaneously the compressing tablet 5 of copper system, prevent to be floated and break away from reference column by water slug with suitable increase float weight.
When tap water pipe line during in normal water inlet, water can enter from last inlet opening 4 and following inlet opening 7, and the impact of water is lifted float 2, and big water gaging enters the inlet opening on impeller box thus, impacts impeller and produces and count.Open very for a short time or pipeline when weeping occurring when water tap, hydraulic pressure is low can't push the float water inlet open, and water clock water can only enter through the impeller box inclined hole from last inlet opening, and little because of last inlet opening, hydraulic pressure is big, also can impact the impeller counting, and antidrip is effective.
Claims (3)
1, a kind of water meter water strainer, it comprises case (1), case is provided with the inlet opening, it is characterized in that described case bottom is provided with into water cover (6), last inlet opening (4) is located on the periphery at case (1) top, following inlet opening (7) is located at on the water cover (6), is provided with reference column (3) in the water inlet cover, and float (2) is sleeved on the reference column and is fitted on the case inner bottom surface.
2, water meter water strainer according to claim 1 is characterized in that described water inlet cover (6) is the hollow cone bodily form, and the following inlet opening (7) on it is distributed on circular conical surface and the bottom surface.
3, water meter water strainer according to claim 1 and 2 is characterized in that also being provided with in the described float (2) compressing tablet (5).
