Is it possible to use ordinary valves to control the flow rate of hot water being discharged?
The use of a steam trap enables effective control of drainage, resulting in good energy savings. However, the valve cannot adjust automatically; the water flow rate remains fixed, which makes adjustment difficult and may lead to excessive steam release, causing significant waste
Using a steam trap can help save energy when the steam flow is high; moreover, using a globe valve directly may result in a large amount of steam being released, which poses a safety hazard
Use a strainer for safe and energy-efficient operation. Valves result in high steam consumption, making them unsuitable for long-term operation under such conditions
There are two methods. In the first method, a large amount of water is used; a condensate tank is designed and the liquid level is controlled through valves, which helps save energy as no steam is lost. The second method involves using return water traps. This approach is simple, requires less investment, takes up less space, and needs minimal maintenance – it is suitable for low-volume steam condensates. However, some steam is lost along with the condensate. The choice depends mainly on the volume of steam condensate
Why isn’t such a great device as a desiccant trap used, when it’s not expensive?
Generally, a trap is equipped with a backup bypass valve; the trap is used under normal conditions, while the bypass valve serves as a temporary replacement in case the trap fails.
It’s possible, but it will result in steam waste or a slow heating speed.
It’s not necessary either; connecting the valve directly, without a steam trap, will result in steam waste. In engineering, a design using a steam trap along with a bypass is commonly adopted; this allows steam or the condensed water in the pipeline to be discharged by opening the bypass when there is a large amount of condensed water accumulated in the pipeline or when the steam trap needs to be replaced. After the condensate in the pipeline has been drained or the steam trap has been replaced, close the bypass and open the steam trap.
First, the pressure of the heating steam needs to be considered; if the pressure is low, a gate valve can be used. However, for safety and energy-saving reasons, it is advisable to use a steam trap valve
