ASTM A216-WCB Thermodynamic Type Steam Trap For Steam Pipeline Use

Product introduction:

Thermodynamic steam trap is currently the most commonly used type of drain valve in thermal system devices. It has the advantages of small size, light weight, large drainage capacity, and easy installation and maintenance.

The thermodynamic steam trap valve is mainly composed of valve body, valve cover, valve disc, air isolation (insulation) cover, filter screen, and filter holder. The only operating component of a thermodynamic steam trap is the valve plate. The operating principle is based on Bernoulli's law and the physical characteristics of steam and condensed water. By discharging drilling water, the dynamic and static pressures acting on the valve plate are changed to open and close the valve plate.

Product component and performance:

Product application:

1. Advantages:

- Simple and compact structure: lightweight, with only one movable valve plate inside, easy to maintain, and can be repaired without removing it from the pipeline.
- Widely applicable: can be used for high-pressure and superheated steam, resistant to water hammer and vibration, stainless steel structure resistant to condensation water corrosion.
- Good energy-saving effect: It can block the direct discharge of steam, save heat conversion in the steam system, and achieve energy-saving goals.
- Easy installation: The installation method is not limited and can be installed freely without the need to build a water tank or storage tank, saving civil engineering investment.
- Long service life: The internal key components are made of stainless steel and other materials, which are corrosion-resistant. The spring force can be adjusted as needed to extend the service life.
- Stable and reliable operation: The main components have strong anti-interference ability, high stability, few faults, and can achieve online maintenance.
- Good environmental performance: No need for external energy, no pollution emissions, and no secondary pollution to the environment. one thousand two hundred and thirty-four

2. Disadvantages:

- Large steam waste: The working power comes from steam, and there is a certain amount of steam waste.
- Loud noise: It produces noise during work and is not suitable for places with high quiet requirements, but a muffler can be installed to reduce noise.
- Relatively short service life: The valve disc works frequently and has a short service life.
- The working pressure range is limited: it cannot work under low pressure difference, the inlet pressure is generally not less than 0.25 bar g, and the back pressure cannot exceed 80% of the inlet pressure.
- During the start-up phase, there may be limitations: if the inlet pressure increases rapidly and the air flow rate is too fast, air resistance may form. It is necessary to install a thermal static exhaust valve in parallel or choose a drain valve with a built-in anti air resistance disc.

In summary, thermal power drain valves have the advantages of simple structure, easy maintenance, and wide applicability. However, they also have disadvantages such as steam waste and high noise. When choosing to use them, it is necessary to consider the specific working conditions and needs comprehensively.
