The utility model comprises a first channel connected with a water inlet; a second channel connected with a water supply port; an inner meter core; a measuring display unit arranged above; a third channel normal to the axial lines of the first channel and the second channel; and a mandrel arranged in the meter core. The mandrel is connected with a fin below and the measuring display unit above, and is provided with a shaft sleeve inside. The shaft sleeve consists of a main body, a flaring petal-shaped part partly extending upwards and outwards from the main body, a valve clack which is enclosed on the main body of the shaft sleeve and can move relatively, and a film connected with the valve clack and the third channel interface. The water meter has the advantages of large measurement range and high measuring accuracy.
Description
Technical field
The utility model relates to the water meter that is used to measure heavy caliber water system water consumption, particularly vertical helical vane type water meter.
Background technology
The heavy caliber water system with respect to the domestic water supply system and, be generally used for commercial production and large-scale building group, it requires to have bigger output, employed feed pipe generally is not less than 50mm, to the water consumption of demand like this, discharge (cubic metre/hour) and the metering of actual used water amount that the water meter unit interval can pass through are that pendulum is in person skilled in art's problem to be solved.The former is relevant with the flow commonly used of water meter, and then the range of influence table; Measuring accuracy under the low discharge of the latter and table is relevant.The water meter that now is used for the water measurement amount is a rotor water gauge, it has rotating shaft, a plurality of aerofoils that separate each other extend radially outwardly from rotating shaft, when user's water, water enters the water inlet interface of water meter from water supply line, current rotate laggard water outlet interface of going into water meter promoting aerofoil through the cavity that rotor is housed, and the water pipeline through the user uses with water spot for each again.Obviously, whether the accurate measurement of discharge that the unit interval can pass through and actual used water amount depends on the structure of the structure, particularly rotor of water meter.Rotor water gauge with 100mm is an example, and its flow commonly used has only 50 cubic metres/hour, and obviously range is narrower, and minimum flow is 1.40 cubic metres/hour, and the initiating flow is 0.40 cubic metre/hour.Such water meter is difficult to satisfy the demands.
Summary of the invention
The purpose of this utility model is to provide a kind of vertical helical vane type water meter that can overcome the prior art deficiency.
Above-mentioned purpose of the present utility model is to realize by following solution.
Comprise a table body according to vertical helical vane type water meter described in the utility model, this table body has an into first passage of water interface that contains that is connected to water supply line, a second channel that contains the water outlet interface that is connected to the water pipeline, one is equipped with watch core in it, metering and display device is housed on it, the third channel vertical with first and second passage axis, it is characterized in that described watch core have one with the water inlet mandrel vertical with the water outlet direction, the one end is connected with fin, the other end is connected with described metering and display device, an axle sleeve is housed therebetween, described axle sleeve has a main body, on this main body, have from bottom to top and the flap part of the flare profile that stretches out, on the described flap part, between downside and described axle sleeve main body at least two reinforcements are arranged respectively, a flap passes described axle sleeve main body, the diaphragm that has the sealing joint of the third channel that passes described axle sleeve main body and described table body to join on the flap, one what link to each other with the third channel interface is the table lid that metering and display device is housed in it.
Vertical helical vane type water meter of the present utility model in use, when the user turns on the water device, water enters from the water inlet interface of the first passage of water meter, promote the fin rotation of following table in-core at the pressure of water inlet, current direction upper edge axis curl rises, and promotes flap along upwards lifting of axle sleeve, and the diaphragm on the flap is out of shape thereupon, until the maximum height that allows, this moment, current flowed out from the water device through the second channel of water meter and user's water pipeline.
When user's water no longer, close when using aquaporin, flap and diaphragm no longer include the current supporting, under the effect of the restoring force of the weight (weight of diaphragm can be ignored with respect to flap) of flap self and diaphragm, flap falls back on the watch core along axle sleeve, diaphragm also restores to the original state, and no longer include water and can enter second channel this moment.
Vertical helical vane type water meter of the present utility model is compared to rotor water gauge, length by the mandrel between watch core and the metering and display device of having extended, increased axle sleeve therebetween with tubaeform profile flap part, flap and diaphragm, thereby making the process that supplies water from intaking to is a spiral vertically upward process that has promoted the pressure of water, the influence that brings thus is: first, increased the flow commonly used of water meter, the range of water meter is widened, evidence, water meter with the 100mm bore is an example equally, can reach 90 cubic metres/hour, improve 80%, in other words under the condition of the water meter of identical bore than rotor water gauge, the rotor water gauge that the gageable user's water consumption of vertical helical vane type water meter of the present utility model compares improves widely, thereby makes the both sides of supply and demand of water all save spending.The second, the pressure of water increases, and has reduced the initiating flow of water meter, water meter with the 100mm bore is an example equally, the initiating flow of vertical helical vane type water meter of the present utility model is 0.10 cubic metre/hour, and rotor water gauge is 0.40 cubic metre/hour, has improved four times.Moreover, the gageable minimum flow of water meter is reduced to 0.40 cubic metre/hour from 1.40 cubic metres/hour of rotor water gauge, has improved measuring accuracy, makes charge more reasonable.
Except above-mentioned points, the axle sleeve of vertical helical vane type water meter of the present utility model and flap are enclosed, and the water that just can not occur in the water meter overflows to metering and display device, thereby have guaranteed that metering and display device is clean and tidy and be easy to reading.The more important thing is that it is digital working as metering and display device, will help data transmission.
According to an embodiment of the present utility model, when the axis runout first passage of the third channel of water meter and the axis of second channel, it will help being contained in the parts maintenance in the third channel.
Above-mentioned purpose of the present utility model and other purposes and advantage thereof will be more readily apparent from by the detailed description below in conjunction with the accompanying drawing illustrated embodiment, and accompanying drawing has:
