Everyone knows ball, semi-reversible valves that displaced the standard valve type from the everyday life of residents of apartments and houses. Its design is simple, like a Kalashnikov machine gun.
It seems that there is nothing to add to its design, but recently, at one of the seminars on engineering plumbing, I came across a ball valve of a special design, which is not yet widespread. In addition, the manufacturer has a patent for this device and they exclusively release it.
I deliberately do not name the manufacturer, so that I am not unfoundedly accused of advertising, but I submit information in order to broaden the horizons of the reader. Who cares can be asked in the comments.
It looks like this:
Scrolling through the gallery, you can see that he has a patent, that is, the manufacturer solely releases this design. Made in Italy. Marked PN 30 (rated pressure withstand)
If you paid attention, then this valve has a plug in the lower part, in the form of a threaded cap.
And there is an arrow on the body for correct installation, why do you think the direction of flow is indicated?
Before revealing the full functionality of the shut-off valves, I want to demonstrate to you the standard set of fittings that it replaces.
Yes Yes. The patented ball valve replaces one conventional filter and two shut-off valves. Now I'll tell you how it works, but first, visually familiarize yourself with its design.
Its principle of operation is based on shutting off the fluid flow, like all standard taps, but except this, due to the special design of the polished ball and body, it contains a 500 micron. And in order to clean it, you do not need to drain water or coolant, which is especially important for heating systems, but you just need to close the tap. Thus, cutting off the pipeline with pressure from the filter.
To explain in a popular way, I was not too lazy and drew a diagram of the filter tap:
Objections naturally arise, but is it not easier to install a faucet filter? Yes, of course you can, but it closes the flow on one side, while our "patient" on two sides. It takes up much less space, especially when working in cramped conditions, during the initial installation of water meters in the old fund, now this problem is not so urgent. It has fewer connections than standard fittings and therefore less risk. As for me, the only drawback of the "tricky fittings" is its price. Since it is produced in Europe and has a patent for an invention. But in any case, functionality prevails over price. I will set myself.
