What valves can be used to control the type of gas intelligent water meter electric control valves

Control valve, ball valve, butterfly valve, gate valve can be used to control the gas valve, they are how to control the gas, the following is a small series of detailed knowledge, including the structural characteristics and working principle of these control gas valve.
The regulator
Regulating valve he is widely used in industrial systems of a control element. The regulating valve is composed of an executive organ and a valve. According to the different executive organs, it can be divided into pneumatic regulating valve, electric regulating valve and self-regulating valve. Control valve by accepting industrial system output 4-20MA control signal to achieve automatic regulation and control of the air.
Ball valve
Ball valve is one of the valves widely used in the world, but also in the past ten years the rapid development of the valve. It is mainly used for cutting off, regulating and distributing in pipelines. It is a multifunctional valve widely used in gas control. The ball valve only needs the spool to rotate 90° to complete the opening and closing and quickly cut off the role of the medium.
Butterfly valve
Butterfly valve is a low cost, simple structure of the valve, so the butterfly valve is more suitable for large caliber. Butterfly valve is characterized by large flow capacity and small fluid resistance. As long as the butterfly plate reaches 90°, it can be opened and closed once, so as to achieve the automatic switch of the pipeline and the cut-off and control of the gas.
Gate valves
Gate valve consists of valve body, seat, stem, gate, valve cover, sealing ring and other parts. The advantages of gate valve are compact structure, small fluid resistance, long service life, through the valve plate up and down movement to achieve the valve opening and gas control, when the gate valve is closed, the sealing surface depends on the medium pressure of the sealing surface of the gate plate to the other side of the valve seat to ensure the sealing surface of the sealing surface.
Intelligent water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology and intelligent IC card technology to measure water consumption and transfer water consumption data and settle transactions. At present, the main types of domestic water meter electronic control valves are ball valve, ceramic valve and diaphragm valve.
Intelligent water meter is a new type of water meter which uses modern micro-electronic technology, modern sensing technology and intelligent IC card technology to measure water consumption and transfer water consumption data and settle transactions. At present, the main types of domestic water meter electronic control valves are ball valve, ceramic valve and diaphragm valve.
Type of electric control valve of intelligent water meter
(1) ball valve
Ball valve due to the requirements of the driving torque, due to scaling or wear in use, it is easy to leak, switch failure and other problems, domestic intelligent water meter using such valves more, in the use of the most problems.
(2) ceramic valve
The ceramic valve has long service life, high switching reliability, small pressure loss, and is not easy to scale in use. Because it is a patent product, the manufacturers of the domestic intelligent water meter use this valve are few and far between.
(3) diaphragm valve
Diaphragm valves are rarely used by manufacturers because of their high cost. Intelligent water meter valve is also a crucial performance index in use.
Due to the water quality of the pipe network, the damage to the water meter valve is serious, which directly affects the metering of the water meter. The selection of the electronic control valve must have a long life, high reliability of the switch, small pressure loss, and it is not easy to scale in use. At present, the ceramic valve is the priority.
