What's the tool for changing water glass?
The same specifications of glass, open the water meter shell special tool, if the gasket broken, find the gasket;A basin of water to clean up the stolen goods in the water meter; a transfer device, installed to see whether the measurement is accurate; pressure device to see whether the installation of water leakage
Don't need a professional tool, of course to remove meter independence from in the pipeline, is the need to use the wrench, pipe wrench (general household recommended 14 inch, up to the maximum opening, which is to be opened, just barely enough clip header, just can clamp meter above the head, this clip is the most convenient on both sides of the connecting tool etc.). Here comes the need for water meter installation pipe clamp is said in aluminum pipe hose pipe, if the meter is installed in the galvanized iron pipe, does not need the pipe clamp, removed when only one 12 inch wrench.
Then independent meter for the glass cover, you can not get any professional tools, only a small hammer. Find the water above the golden copper lid four lobes (ear) the most stout, gently tapping with a hammer, with patience, action to light, otherwise it will knock on the fracture may of course angle, the rest of the three corners of the best turn out of a few, a full range of shock and loose best. Light knock on a corner of the copper will break the weak. It is an important direction, counterclockwise or clockwise, one that is not good, and generally seems to be with words (such as 15MM) arrow in the opposite direction, tapping (must be light, slowly) a few will be released, not to knock on the side, is a hammer knock, and as close to convex the root of knock, with a round wall slide better, so as to better reduce the salient sections of excessive force to fracture problems. Of course, if you can't hit it, change it in a different direction. Only about two directions should be used flexibly. The above operations must pay attention to the integrity of the above copper cover ears, even if only one of the four knock off, the tightening force is much lower, will definitely affect the tightness, the basic copper cover will be scrapped.
