Anti-disassembly, anti-reversion, anti-pulsation, antirust and antidrip energy-saving water meter

Abstract

The invention relates to an anti-disassembly, anti-reversion, anti-pulsation, antirust and antidrip energy-saving water meter belonging to a measuring instrument for preventing the running water from running away and from being stolen. A pipe connector protective sleeve sleeved on a nut for an inlet pipe connector of the water meter is buckled with a protective sleeve retaining ring to enable meter casings to be connected into a whole, a meter cover protective sleeve is buckled on a meter cover and is used for buckling and hooking the meter cover through an interlocking hook, and a positioning pin is inserted on the meter cover and connected into a whole with the meter casings so as to prevent the water meter from being disassembled and prevent the meter cover from dripping water; an anti-reversion and anti-pulsation structure formed by a check valve is arranged in an inlet of the water meter so as to avoid reversion and pulsation; the transmission between an impeller and a counting device is carried out through an ultra-thin gear transmission shaft and a lip-shaped sealing ring, and an antirust structure for a meter panel can prevent the water from entering in the counting device to cause the meter panel to rust; and symmetrical microflow holes, a recharging hole and a dead weight valve on an impeller case of the water meter and a flow regulation valve on a valve plate form an antidrip structure to avoid a dead angle to affect the accuracy in the rotating process of the impeller and water from dripping, therefore, the invention integrates the five precaution functions into a whole and plays the roles of fair water supply and water saving.

Description

Technical field [0001] The utility model is an energy-saving metering instrument used in a tap water supply system to prevent tap water from leaking, dripping, leaking, and stolen water. water meter. Background technique [0002] At present, my country is a big water-deficient country, and water conservation has been included in the national key plan. Since most of the existing water meters do not have an anti-disassembly device, the old-fashioned lead seal is still used. Some people pull out the lead seal line of the water meter, open the water meter cover and adjust the meter needle to steal water, and some people remove the water meter to steal water, or put the water meter Loosen the joints at the front end to steal water at will. Although some water meters have anti-disassembly devices, they are complex in structure and easy to disassemble and produce waste products during installation. Some dials are seriously rusted and can only estimate the water consumption. The m...
