Product Description
Water Heater Valve
The Water heater valve is used for automatic control of hot water and other viscosity ≤28cst in the liquid medium pipeline, it can automatically open or close the valve after receiving the electric control signal, to achieve on/off or flow regulation control of the fluid medium in the pipeline, so as to the system temperature, flow, pressure and other parameters for automatic regulation or remote control.
The KANGLEDA Water heater valve is in the gas water heater, its role is to open or repeatedly close the gas pipeline is to prevent water pressure is not enough in the case of the hot water system will dry burning, control solenoid valve 100 is water pressure flow sensor, water pressure is not enough when it will not be connected to the solenoid valve degree of power, the solenoid valve will not open, igniter can not fire.
Water and gas linkage device includes a water control device and an air control device. The principle of operation is to start the gas mechanical switch (straw hat pad), start the circuit (generally a microswitch), and then start the motor, pulse igniter, and electromagnetic valve when sufficient impact water pressure is detected.
Water and gas linkage device (commonly known as water and gas linkage valve) includes water control device and air control device, the main components are air inlet, pressure relief valve stem, conical tube, eardrum, water temperature control valve, pushrod, micro switch, fire control valve, electromagnetic valve, air inlet, etc.
Water control, air control device
1. the air control device is composed of the air valve assembly, controls the opening and closing of gas and gas flow, also known as a fire control valve.
2. the water control device is to control the flow of water devices, also known as the water temperature control valve.
Working principle of water - gas linkage
The function of the water-gas linkage device is to ensure that the gas control valve can be opened only when the water pressure is sufficient and the heat exchanger is introduced to flow. When the water flow stops or the pressure is insufficient, the gas supply path of the gas will be cut off automatically to prevent the equipment from burning out due to lack of water, which is commonly referred to as "water to, gas to".
Working principle, in a nutshell, is to detect enough shock pressure, start the gas mechanical switch (straw mat), start-up circuit (general microswitch) and then start the motor, pulse ignitor and electromagnetic valve (gas electronic valve, attention, there are two valves on the gas, it is the request of safety, and also the mandatory national standard requirement).
Now commonly used water - gas linkage mainly has two kinds: one is the pressure type, the other is the differential pressure type.
Working principle of water - gas linkage1. Differential pressure equation:
Using the principle of the pressure difference of water on both sides of the film, the pipeline is equipped with a throttle hole (venturi tube). When water flows through the throttle hole, the pressure difference is generated on both sides of the film, and the pressure difference is used to open and close the gas disc. Because the orifice diameter is fixed, so in unit time flow through the orifice of the more water, the water flow through the orifice is faster, according to Bernoulli principle, the pressure difference between the two sides of the orifice produced by the greater, by the stem control disc, so that the degree of valve opening is also increased. Guaranteed in the hot load range of the water heater, the temperature of the water heater to maintain the basic stability, not hot and cold. When the water valve closes and the water stops flowing, the pressure difference between the two sides of the film disappears, the disc resets under the action of the spring, cutting off the air supply to the main burner, the main burner off (at this time, if there is a small fire burner to keep the original combustion state).
Differential water - gas valve can be used in front of the standard and can be used in the rear.
Water and gas linkage valve is an important part of the connection between water and gas, should choose a good performance of the material for the waterproof film, but also from the structure of the water and gas road strictly separated, so that even if the membrane damaged water will not enter the gas pipeline.
