Description
Technical field: the utility model relates to a kind of magnetic control non-return valve that makes water meter drip and also measure.Belong to the conduit fittings that supplies water and carry the liquid meter instrument.
Background technology: be used at present improve the water meter measurement precision, the servicing unit that also can measure when making the water of water meter in pipeline be in the drip state has a variety of, but since structural limitations, the effect that does not reach imagination that has; Perhaps reaching drips has measured, but influence other flow parameter precision of water meter, do not reach country or international water meter measurement standard, excessive such as crushing, or minimum flow and boundary flow are overproof, the structure that also has is very tight to water quality requirement, if water quality is bad, after using a period of time, impurity or incrustation scale be the metering line clogging of dripping of special use, water meter drip metering will be malfunctioning, that is to say, the water meter that new water meter is newly installed in other words drips and just measures, and after use a period of time, can steal water with the rill method in the same old way.
Summary of the invention: the purpose of this utility model provides a kind of simple in structure, can adapt to various water quality, does not change other measuring parameter of water meter itself, the magnetic control non-return valve that makes water meter drip and also measure.
Above-mentioned purpose realizes by following technical scheme:
The magnetic control non-return valve that makes water meter drip and also measure, its composition comprises: valve body, described valve body internal fixation one magnet carrier, in the axle sleeve of described magnet carrier poppet shaft is housed, be with O-ring seal on the movable valve block on the described poppet shaft, be fixed with one group of moving magnet on the described poppet shaft and corresponding with it decide magnet, described magnet ring outer end is fixed with protective cover.
The above-mentioned magnetic control non-return valve that makes water meter drip and also measure, the center of described magnet carrier is an axle sleeve, described axle sleeve outer end studs with the described magnet ring of deciding.
The above-mentioned magnetic control non-return valve that makes water meter drip and also measure, sealing gasket is equipped with in the junction of described valve body and bonnet, and snap ring is equipped with in described valve body outer face and nut junction.
The above-mentioned magnetic control non-return valve that makes water meter drip and also measure, described moving magnet is the permanent magnet of annular or other shapes, be equipped with by magnetic attraction fixing permanent magnet or magnetic conductor in the outer end of described axle sleeve, the shape of described magnetic conductor and the shape of moving magnet adapt.
This technical scheme has following beneficial effect:
1. the magnetic control non-return valve that makes water meter drip and also measure of the present utility model, utilize the action characteristic between the opposite pole of inhaling mutually, promptly attractive force is very big in extremely short distance, along with the expansion of spacing, attractive force reduces very soon, breaks through thereby form a suction, the flow that makes each water by this device is all greater than the initiating flow of water meter, still can measure when making the tiny flow quantity that water meter produces when one is water clock less than the initiating flow, because the sudden change of suction, the pressure loss that current are passed through is very little.
2. but this product level or be vertically mounted on the front end or rear end pipeline of water meter, when the pipeline after this device has water clock or artificially adopts drip mode water, during beginning, because the pressure differential of valve block both sides is very little, less than the magnet suction of inhaling mutually, valve block is pressed on O-ring seal on the sealing surface at check valve inlet place, water before the valve is motionless, carrying out along with drip, produce vacuum, the pressure differential of valve block both sides increases, when pressure differential reaches suction greater than two magnets, magnet separates suddenly, drives valve block and throws open, and the Shuitu before the valve is so broken through valve body, this water flow is greater than the initiating flow of water meter itself, the result measures water meter, after the pressure differential balance of valve block both sides, because the suction of magnet, moving magnet can drive valve block and push down O-ring seal, current stop, and go round and begin again, and what kind of drip like this don't work, the effect of " accumulative total pressure reduction " by this device, make the water by water meter form the also effect of metering of dripping, if normal water, the pressure differential of valve block both sides is all the time greater than the attractive force of two magnets, valve block is opened, and because the distance of magnet, the pressure loss that suction causes is very little, does not influence the crushing requirement of water meter.
3. owing to generally all contain particulate contamination and ferromagnetism impurity in the pipeline of use water meter; if enter or be inhaled between two magnetic poles; two magnets just can not attract to move to minimum distance; the valve block that is attached thereto just can not the compression seal circle; " accumulative total pressure reduction " phenomenon that the magnetic force sudden change causes is little; whole device just can not be worked reliably; therefore this device fixedly is covered with the protective cover that a stainless (steel) wire or plastics are made at two magnet working portions; impurity during work in the water is owing to be subjected to the momentum effect of water; can not enter between two magnets; therefore this device can be that drip measures to the initiating flow less than water meter long-term effectively; guarantee that whole device works long-term effectively; avoided the loss of water supply department, this device can be fixedlyed connected with the water inlet or the water delivering orifice of water meter, makes dripping water meter.
This product have simple in structure, characteristics such as usability is reliable.
Description of drawings: accompanying drawing 1 is that the master of this product looks cross-sectional view.
