Novel valve-controlled water gauge apparatus

Abstract

The invention discloses a novel valve-controlled water gauge apparatus. The novel valve-controlled water gauge apparatus structurally comprises a quick coupling, a screw cap, a non-return valve, a pointer water gauge, a sealing cover disc, a disc flange, an extraction pipe, an electronic screen, a backlash overflow valve and a valve base, wherein the backlash overflow valve is inserted into the top of the valve base and runs through the valve base, the backlash overflow valve is provided with a linkage pushing cylinder, a water wheel apparatus, an exhaust mechanism, a backlash apparatus, a linkage support, a traction apparatus, a shaft rod mechanism and a turbocharger, an air pressure backlash effect of the valve-controlled water gauge is realized, an air pushing water flow is formed, compared with the mechanical pushing, the air is closer to the water surface, the rapid pressurizing output is realized, the flow rate is increased, the overflow feedback directly influences the backflowand output of the flow rate, when the flow rate is small, the overflow volume is increased to realize the backlash, the dual-controlled adjustment effect of the single part overflow valve is high, andthe air pressure protects a surface oxidation film of the component, so that the fitting accuracy of the component is higher, and more accuracy in driving is realized.

Description

technical field [0001] The invention is a novel valve-controlled water meter device, which belongs to the field of valve water meter equipment. Background technique [0002] With the continuous development of science and technology, the rising cost of human resources and the increasingly tense energy sources, the water industry has higher and higher requirements for remote meter reading; remote meter reading is not only to replace meter readers, but also to Water supply contracts, closing the valves of arrears users, stopping water supply to these users, meter reading to households is an industry vigorously promoted by the country, but meter reading to households requires a lot of manual meter reading, in order to reduce labor costs, it is necessary to set up automatic remote reading The instrumentation equipment of the meter, the valve combination type of the valve-controlled water meter commonly used in the current technology is precise, and the control of the water flow i...

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a new type of valve-controlled water meter device to solve the problem of valve-combined precision of the valve-controlled water meter, and to control the water flow, the effect of mechanical cut-off or opening enlargement is used to control the flow rate and The flow rate is easy to make the mechanical repetitive movement rub against water, causing water erosion and low-pressure oxidation to consume the surface of parts, reducing the anti-corrosion effect of the oxide film, resulting in insufficient connection fluency, inaccurate control of water output and flow rate, and reducing the flexibility of the overall valve.
