Expansion type corrugated pipe drain valveDetailed product description：

CS14f Expansion Bellows Drain Valve:

summary:

The liquid expansion type drain valve is the most economical and energy-saving type of drain valve used in thermal and static experiments. Its advantages are: small size, light weight, not afraid of freezing, able to automatically exhaust air, and can be installed at any position; The back pressure rate is greater than 80%, and the stainless steel corrugated pipe has a large expansion and contraction, which is easy to adjust. The valve is equipped with adjustment bolts, which can adjust the operating temperature according to needs. Generally, the subcooling degree is 18 ℃ -40 ℃ lower than the saturation temperature.

Bellows type drain valves are suitable for steam pipe network tracing, instrument tracing, domestic heating, and drainage of heating equipment that allows the storage of high-temperature condensed water. They have a wide range of applications.

characteristic

1. Stainless steel corrugated tube is sturdy and durable, with a long service life.
2. The discharge temperature of condensate can be adjusted, utilizing sensible heat and achieving significant energy-saving effects.
3. There is always condensed water in front of the valve, forming a reliable water seal without steam leakage.
4. Not affected by vibration, steam pressure fluctuations, and water hammer.
5. Can be installed at any angle, not limited by installation orientation, and has excellent air exhaust performance.

6. The structure is simple and equipped with a filtering device, making it easy to install and maintain.
Working principle of liquid expansion drain valve

The internal structure of the liquid expansion type drain valve is mainly composed of a stainless steel bellows as the main operating element, filled with a liquid with a vaporization temperature lower than the saturation temperature of water. When the device is started, cooling condensate appears in the pipeline, and the liquid inside the corrugated pipe is in a condensed state. The valve core is in the open position under the elastic force of the spring. As the temperature of the condensed water gradually increases, the liquid inside the corrugated tube begins to evaporate and expand, causing an increase in internal pressure, deformation, and elongation, which drives the valve core to move towards the closing direction. Before the condensed water reaches saturation temperature, the drain valve is completely closed. There is always high-temperature condensed water in front of the valve, with no steam leakage and good energy-saving effect.
