Description

Tap water integrated circuit (IC) card single card microcomputer observing and controlling differential pressure valve coenosarc water meter

The utility model relates to a kind of tap water meter, particularly relates to a tap water and pre-pays water rate IC-card observing and controlling differential pressure valve coenosarc water meter.

The tap water supply system practicality so far, the water meter that is used for tap water metering is a kind of monomer structure device always, never is combined into one with valve body.In recent years, tap water pre-paying IC-card intelligent observing and controlling system is being promoted again in domestic various places, and the gauge tap of this system no longer is that traditional single channel manually rotates water valve, but a kind of differential pressure type water valve of novel binary channels automatic open close.But this kind differential pressure type water valve majority is the heavy copper structure of alloy in the market, and its two pipe nipples silk mouth is a female thread structure, complex structure, and cost is too high, and inconvenience is installed.While water gage water valve monomer separation takes up space bigger, and the labour intensity height is installed, and workload is big.

The purpose of this utility model provides a kind of tap water integrated circuit (IC) card single card microcomputer observing and controlling differential pressure valve coenosarc water meter, and it can remedy the above-mentioned deficiency of existing water meter.

The utility model comprises an existing water meter, it is characterized in that a water chamber is arranged on the housing of this water meter, in a water outlet rim of the mouth is arranged, the latter communicates with rising pipe is vertical straight down, water outlet rim of the mouth upper cover one cymbals shaped rubber pad, one spring is arranged on the cymbals shaped rubber pad, and there is a valve gap cymbals shaped rubber pad top, and split channel is arranged in the valve gap.

The utility model has the advantages that simple in structure, compactness, volume greatly reduces, and is easy to use, reduced the labour intensity of installing, and pushes the domestic consumer to for tap water pre-paying IC-card single card microcomputer measure and control device and created a good condition.

Below by embodiment and description of drawings the utility model.

Accompanying drawing is a structural representation of the present utility model.

The utility model comprises an existing water meter, and water meter is made up of housing (5), water meter movement (containing O-ring seal and glass watch glass) (4) and water meter spiral cover and dust cover assembly (3).On the housing (5) of this water meter, a water chamber (B) is arranged, in a water outlet rim of the mouth is arranged, the latter communicates with rising pipe is vertical straight down, water outlet rim of the mouth upper cover one cymbals shaped rubber pad (1), one spring (6) is arranged on the cymbals shaped rubber pad (1), there is a valve gap (2) cymbals shaped rubber pad (1) top, and valve gap has split channel in (2).Accompanying drawing cavity A is called diffluence room, and cavity B is called the main flow chamber, and the two by cymbals shaped rubber pad (1) separately; Cavity C is called the pulpit, and the frustum endoporus in the C of pulpit is called shunting water outlet rim of the mouth.From then on shunting the water outlet rim of the mouth is called along the downward to the right passage of single direction of arrow and distributes aquaporin.The pore of first left list arrow indication is called the shunting water inlet in the accompanying drawing.From then on shunt water inlet and upwards only be called shunting and go into aquaporin to shunting the water outlet rim of the mouth along single direction of arrow to the right, aquaporin is gone in shunting and exhalant canal is collectively referred to as split channel.Go into to have a vertical core to lead to the A of diffluence room downwards under the letter C on the aquaporin and upwards lead to pulpit C in shunting, the A of diffluence room is a storage pressure chamber.Water in the A of diffluence room changes with its density of variation of hydraulic pressure, but does not flow.The passage of four multiple arrow indications is called mainstream channel, the water outlet rim of the mouth of cymbals shaped rubber pad (1) below is called main flow water outlet rim of the mouth, passage is called the main flow exhalant canal shown in two the multiple arrows in the right, water passes through the interior rotor cavity of filtering screen of water meter movement (4) bottom along the direction of first multiple arrow of left end, upwards turn right then to the main flow chamber B of part shown in the multiple arrow of second left, to (1) one section of cymbals shaped rubber pad, be called the main flow intake tunnel again.

When using the utility model, its main flow intake tunnel mouth and main flow exhalant canal mouth are inserted on the water supply line, it is preceding that servo control mechanism is not opened shunting water outlet rim of the mouth (being blocked by a glue), after A, B, C three chambers all were full of water, because the A of diffluence room is identical with hydraulic pressure among the B of main flow chamber, promptly the pressure differential of cymbals shaped rubber pad (1) upper and lower surface was zero, at this moment, cymbals shaped rubber pad (1) is blocked main flow water outlet rim of the mouth under the elastic force effect of spring (6), therefore, does not have current on the main flow exhalant canal.When servo control mechanism with glue stifled mention open shunting water outlet rim of the mouth after, there is water to flow on the split channel, thereby the hydraulic pressure in the A of diffluence room descends, the pressure of cymbals shaped rubber pad (1) suffered water in the B of main flow chamber is greater than the pressure of water suffered in the A of diffluence room, when the two pressure differential during greater than spring (6) elastic force, cymbals shaped rubber pad (1) is just by the water jack-up in the B of main flow chamber, thereby main flow water outlet rim of the mouth is opened, and just has water to flow in the mainstream channel.If servo control mechanism cuts out shunting water outlet rim of the mouth once more, then can reenter the described closed condition of this section beginning, no longer include water in the mainstream channel and flow.When having water to flow in the mainstream channel, the water in the rotor cavity of water meter movement (4) below also flows, thereby promotes the rotor rotation, and passes to display device by the reducing gear in the water meter movement, reaches the purpose of counting.When anhydrous when mobile in the main flow exhalant canal, the water that main flow is gone in the aquaporin does not all flow.Thereby the water of water meter movement rotor cavity is also mobile, also just can not drive rotor, and rotor is static, the digital no change that the water meter display device is shown.

The utility model except valve gap and position, rim of the mouth adopt alloy copper, the overwhelming majority of housing is a cast iron matter, thereby has alleviated weight more, has reduced cost.

Differential pressure valve part of the present utility model can also be changed into the left side of existing water meter case.
