3 WAY VALVE

3 Way Valve 

Fig. 3 way valve 

  •  The functioning of a 3-way valve is significantly different from other types of valves, which typically only operate in a 2-way manner. Unlike 2-way valves, the 3-way valve can control the fluid exchange between three separate transfer lines. For better control, the 3-way valve is usually paired with an actuator which itself is powered pneumatically, by electricity, or by temperature.
  • One of the functions of the 3-way valve is to completely shut off flow to one pipe, while at the same time allowing for fluid transfer to begin in a connecting pipe. The valve can also be used to mix two of the liquids that are being sent through the pipes. Lastly, the 3-way valve can take fluid from a single pipe and separate it into two pipes. And while all 3-way valves work similarly, there is a vast array of different valve sizes, which have varying flow rates.

  • The 3-way valve is perfect for controlling the flow of three separate fluid lines, which allows it to regulate temperatures efficiently. The 3-way valve can shut off one pipe while allowing another to open, which can change the temperature of the fluid being output.
  • Also, the 3-way valve can be used to mix varying levels of hot and cold fluids by letting specific amounts of each fluid come together, thus changing the overall temperature. Some applications utilize 3-way valves, and one of the most popular is in radiator systems. Also, the 3-way valve is used in controlling the temperature of flooring systems. To accomplish this, the valve is usually paired with an actuator which is connected to a controller, and this will tell the valve when to open and close.

Why Distilled water is not circulated in the pipelines ?

1.Why Distilled water is not circulated in the pipelines ? Ans. In Fwg distilled water is generated still it is not directly used in Boiler without chemical dosing even it is free from contaminants . The reason to the question is distilled water ready absorption carbon dioxide and tends to become slightly acidic which can cause corrosion . 2. What is the highest temperature at which a fuel of 60 deg Flash point should be heated to achieve a certain viscosity? Ans. Less than 20 deg of its Flash point i.e 40 deg . And the reason is near its flash point tempeature fuel starts to vaporise 3. What is the percentage water of get distillated from 100% of sea water? Ans. It is around  50% rest do formation of brine , scale of carbonates and bicarbonates .

Difference between Attemperator and De-superheater

Attemperator are fitted in order to keep the steam temperature in the final stages of the superheater within certain desired limits . This is done for two main reasons . 1. The most important is the protection of the superheater tube material from the effects of overheating. *Mild steel superheater tubes tubes should not be subjected to steam temperatures in excess of 455℃. 2. The formation of bonded deposits on superheater tubes can be reduced if steam and gas streams within certain temperature ranges are prevented from coming into contact of each other. De-Superheater is used to reduce the temperature of a quantity of superheated steam and make it suitable for used in auxiliary services requires low temperature or saturated steam . *The reason for doing this way rather than by taking the saturated steam direct from steam drum , is to protect the superheater , these must be protected against overheating under all conditions of load by circulating steam through them . *Al...
