Description
Technical field
The present invention relates to machinery valve technical field, particularly relate to stop valve before a kind of multifunctional meter.
Background technique
Water meter is a kind of flow-meter, is the measurement instrument of correct metering and reasonable distribution water resources.In principle, be generally rotating vane type water meter for civilian water meter, belong to the one in velocity type water meter.The bore of domestic water meter is generally 15mm ~ 40mm, and with 15mm bore is many.Affect a lot of because have of water meter degree of accuracy, people usually give suitable concern to the degree of accuracy of water meter product itself, and often ignore other links.To install in undesirable, improper use, water containing air, water quality inferiority, exceed the re-testing periods and use, all can affect the degree of accuracy of water meter.
The first, install lack of standardization larger on accuracy of measuring impact.Install and use by regulation water meter level of answering, if water meter tilts to install even at right angle setting, not only can affect the accuracy of measuring of water meter, also can shorten the working life of water meter.In addition, water meter also has requirement to upstream flow development length and downstream flow development length when mounted, and for the water meter of bore 15MM, at least should there be the straight length of 150MM upstream, and at least should there be the straight length of 75MM in downstream, otherwise, will the accuracy of measuring be affected.
The second, be mixed with air in water, often stagnant there is water meter top regulator and other higher spaces in, directly cause the many numerations of water meter.Moreover, these air of ensconcing water meter inside also can make regulator weaken the counterattack effect of water, make the instruction water yield of water meter additionally increase further.
3rd, desirable water source should be clean, if foreign material are more in water, when current are by water meter, on the impeller that these dirts can be attached to water meter or on the wall of water meter, the dumb or metering zone flow velocity of wheel rotation is caused to accelerate, make metering inaccurate, and then damage water meter.Sometimes, water source is clean, but aqueduct inwall is very dirty, finally also result in deteriorating water quality.
Valve before the table of stop valve one class is usually installed before water meter, before table stop valve be installed on water meter before for cutting off and connect the current in pipeline.Stop valve and water pump composite are in conduit shaft, and conduit shaft is not of uniform size, and water meter line length of installation is often restricted, and stop valve has been connected rear position is all fixed with water meter, water meter verification, pipe-line equipment safeguard change inconvenient.The Chinese patent of Authorization Notice No. CN2512968Y discloses a kind of stop valve used that matches with water meter, and comprise valve body, valve gap, valve rod, valve body one end is connected with telescopic pipe, is provided with O-ring seals on the left of telescopic pipe, and snap ring snaps in valve body groove.Complete the sealing between valve body and telescopic pipe by O type circle, snap ring restriction telescopic pipe departs from valve body.Disclosed stop valve and other subject matter existing for similar valve used that matches with tap water meter of above-mentioned patent is, straight tube to be used during water pump composite, to silk, reducing straight joint, mend the links such as core, cause pipe fitting and conversion part is more, install contact also many, many, the poor reliability of leakage hidden danger, silk, the direct first-class Malleable Iron Pipe part of reducing are easily got rusty simultaneously, cause leakage.
