Embodiment 1
[0022] Such as Figure 1-4 As shown, a filter screen inside a water meter, the cylinder body 1 is open at one end, and several water outlet holes 2 are opened through the side wall of the cylinder body 1, and the water outlet holes 2 are evenly distributed along the circumference of the cylinder body 1, The bottom of the cylinder 1 is provided with several water holes 3, and the inner wall of the cylinder 1 is provided with a plurality of water diversion plates 4, and the water diversion plates 4 extend along the side wall of the cylinder 1 to the bottom of the cylinder 1. At the bottom, two rows of outlet holes 2 are arranged between every two adjacent water dividing plates 4, and each water dividing plate 4 points to the axial direction of the cylinder body 1, and the left and right sides of the water dividing plate 4 A "v"-shaped groove 5 is evenly arranged on the wall, and the "v"-shaped groove 5 is parallel to the inner wall of the cylinder body 1. A plurality of water wa...

Abstract
The invention provides a filter screen in a water meter, which relates to the field of water meter filter screens. The filter screen comprises a cylinder body, wherein a plurality of water outlet holes are formed in the side wall of the cylinder body in a penetrating manner, a plurality of water through holes are formed in the bottom of the cylinder body, a plurality of water distribution plates are arranged on the inner wall of the cylinder body and extend to the bottom of the cylinder body along the side wall of the cylinder body, v-shaped grooves are evenly formed in the left side wall andthe right side wall of each water distribution plate, a plurality of water wave baffles are evenly arranged at the tail end of each water distribution plate, water flow gaps are formed between the water wave baffles, and water flow gaps are formed in the water wave baffles in a penetrating mode. Through the arrangement of the water distribution plates, a very good blocking effect can be achieved on rotating water flow, the water flow can only flow out towards the water through hole in the bottom of the cylinder body along the water distribution plates; and by arranging the V-shaped groove, theflowing water flow can be buffered, so that the power of the whole water flow is reduced, the vortex of the water flow can be weakened, the detection stability of the water meter is improved, and theservice life of the filter screen is prolonged.
Description
technical field [0001] The invention relates to the field of water meter filter nets, in particular to a water meter inner filter net. Background technique [0002] A water meter is a common tool for measuring liquid flow. Its operating principle is that when water enters the impeller box from the water meter case and impacts the impeller, the impeller generates a driving torque. When the driving torque of the impeller is greater than the resistance torque of the impeller, the impeller starts to rotate. , the rotation angular velocity of the impeller is realized by the dial counting device installed in the water meter casing to realize water metering. In order to reduce the dirt in the tap water from entering the impeller box and adhering to the impeller of the impeller box, which will affect the accuracy of the water meter, it is necessary to filter the tap water before entering the impeller box. [0003] In the prior art, it is impossible to overcome the influence of the ...
