Large caliber intelligent water meter

Introduction:

Large caliber intelligent water meter is a new type of measuring instrument that uses a new microprocessor to collect, process, display, and store water volume. It is the preferred solution for the majority of water management departments to achieve intelligent management and an ideal choice to enhance the public's awareness of water conservation. This product has multiple water meters with stable performance, and the valve drive is not affected by high or low water pressure. It is used by the water supply company to pay users for drinking water flowing through the tap water pipeline before using it. Its application will completely change the traditional method of meter reading, charging, and metering for tap water.

Advantages of large-diameter intelligent water meter products:

(1) The self-supporting pilot structure allows the pilot valve to open without the need for large torque, while the main valve can be activated solely by the water pressure of the valve itself, solving the problem of no large power supply in the large meter well;

(2) The guiding valve adopts the principle of floating ball valve, only changing the original needle valve structure to ensure that the guiding valve is not blocked or malfunctioning, ensuring normal opening for tens of thousands of times;

(3) The guiding valve adopts the duplex principle, which can prevent water from flowing back when the water pressure at the front end drops, and has a slow closing check function;

(4) The main valve adopts the principle of American diaphragm valve to ensure that the main valve will not get stuck, and the disadvantage of piston valve has been improved;

(5) The main valve has a wide flow to ensure high flow rate and low pressure loss;

(6) The diaphragm valve is made of EPDM rubber, with a two-layer nylon mesh cloth in the middle, which greatly enhances the product's service life and performance;

(7) The main valve core shaft is made of stainless steel and the valve seat is made of copper. The guide valve components are all made of copper, ensuring the overall performance of the valve and preventing problems caused by embroidery.
