What valves are there in the steam-water pipeline of natural gas boiler?

The natural gas boiler heats water into hot water, which can be used for heating and bathing. It is an important accessory of natural gas hot water boiler, and it can cooperate with other equipment to ensure the long-term stable operation of the boiler. As the user is consulting which valves are in the steam-water pipeline of natural gas hot water boiler, here, ZOZEN Boiler will answer for you.

What valves are there in the steam-water pipeline of natural gas boiler?

Various valves commonly used in gas-fired hot water boiler systems include safety valve, blowdown valve, gate valve, globe valve, throttle valve, check valve and pressure reducing valve.

1. Safety valve. A valve for safety protection, whose opening and closing parts are normally closed under the action of external force, automatically opens when the pressure of medium in equipment or pipeline rises and exceeds the specified value, and prevents the pressure of medium in pipeline or equipment from exceeding the specified value by discharging medium outside the system. Safety valves belong to automatic valves.

2. The blowdown valve, evolved from the gate, uses the gear to rotate 90 to drive the valve stem to lift to achieve the purpose of opening and closing.

3. The control valves are divided into rotary control valves and lifting control valves;

4. Check valves, which prevent the medium in the pipeline from flowing backwards, mainly include lift check valves, swing check valves and butterfly check valves;

5. According to the structure, the pressure reducing valve can be divided into spring membrane pressure reducing valve and bellows pressure reducing valve;

There are the following three types of traps: float traps, thermal expansion traps and thermal traps.

The valve is a general-purpose part, and the nominal pressure and diameter of various types of valves are generally used as the selected specifications. The specific valves in the steam-water pipeline of natural gas hot-water boiler should be determined by the medium used, its temperature and pressure, and working conditions, so as to avoid accidents due to improper use.

The above introduction about the specific valves in the steam-water pipeline of natural gas hot water boiler hopes to be helpful to everyone. If you need to buy a complete set of natural gas hot water boiler system, please consult ZOZEN Boiler Online Customer Service.
