Rotor highly sensitive water gauge

Abstract

A rotor-type water meter, including a watch case and a rotor-type metering mechanism at the lower part of the watch case and a corresponding upper indicating mechanism. The impeller box in the metering mechanism is in the shape of a round basin, and the bottom is equipped with an adjustment plate, and the impeller is set on a fixed top. On the top, the water filter net is assembled outside the impeller box; there is a downwardly concave water filter cylinder at the bottom of the water filter net, and there is a guide shaft at the bottom of the water filter net on the outer ring of the water filter cylinder, and the water sealing valve that can move up and down passes through The hole is set on the guide shaft, and there is a square bar on the inner wall of the water filter that closely matches the impeller box. There is a water hole in the square bar, and a jet hole is opened at the position connected to the water hole on the impeller box. , the advantages of this water meter are: a water sealing valve is added on the basis of the original ordinary water meter, and the water filter uses a filter cylinder to enter water, which greatly increases the water passing through the water filter, thus reducing the high sensitivity of the rotor type. Water meter pressure loss.

Description

Technical field: [0001] The invention relates to a rotor type water meter with a nominal diameter of 15 mm to 50 mm Background technique: [0002] At present, the water meters used by my country's water supply department are generally ordinary rotor-type water meters. When the water flow is less than the dynamic flow (the nominal diameter of the 15mm water meter is 10l / h, the larger the diameter, the higher the dynamic flow), the water meter does not measure. Cause many users to take advantage of this point, take the way of using small streams or dripping water to achieve the purpose of not paying for water. In response to this situation, the water supply department has used some high-sensitivity water meters, but some water companies have reported that after using the high-sensitivity water meters currently on the market, the water volume of users on the fifth floor and above becomes smaller, and even no water is used during peak water consumption periods. In the national ...
