◆Overview: The product is composed of a rotor drinking water transmitting base meter, a ball valve (pilot valve), a prepaid circuit and a terminal manager (charging system).The water meter is the meter that is used to meter the total volume of cold (hot) water in the tape water fully charged closed pipe.It can realize prepayment automation and intelligent management. It is an ideal metering and charging instrument of tap water companies and real estate and property management companies for modern management.
◆Performance characteristics:
☆Self-standing pilot structure: a pilot valve can be opened without large torsion, and a main valve can be opened only depending on the water pressure of the valve itself, which solves the problem of no large power driving force in a large water meter well.
☆The pilot valve is designed based on the principle of a floating ball valve and the original needle valve structure has been changed so as to ensure that the pilot valve is not blocked or out of order any longer and thus can be opened normally over ten thousands of times.
☆The pilot valve uses a duplexing principle that can ensure that back-end water does not flow back when front-end water pressure goes down, in other words, it has the closure slowing and non-return functions.
☆The main valve uses the principle of American diaphragm valve so as to ensure that the main valve will not be stuck and the disadvantages of a piston valve are improved.
☆The large and wide flow channel in the main valve can ensure large flow amount and small pressure loss.
☆The diaphragm uses EPDM, nylon mesh with two layers sandwiched in the middle and nontoxic materials, which significantly strengthens the service life and safety of the product.
☆The spindle of the main valve is stainless steel and the valve seat is a copper valve seat, and all pilot valve components use copper parts, all of which ensure the overall performance of the valve, and avoid the problems arising from rusting.
※Based on order requirements, handsets with USB extension cords can be assembled to connect with IC card type, radio frequency external mounting and radio frequency circuit valve body directly brushed with waterproof sealing and other several other sealing methods on their upper end.
