Description

Technical field: [0001] The present invention relates to hydrophobic means on steam delivery pipes. Background technique: [0002] The gas in the steam delivery pipe is steam and non-condensable gas. The steam will produce condensed water in the delivery pipe. If it is not discharged, it will affect the delivery of the gas and accelerate the corrosion of the pipeline. The existing steam trap is composed of a shell installed on the gas delivery pipe. Condensed water, steam and non-condensable gas mixed inlet on the shell, condensed water discharge outlet on the upper cover, filter cartridge on the mixed fluid inlet, the filter cartridge is covered by the floating cup, the floating cup and the upper The cover is connected with a lever mechanism, and the lever mechanism is connected with a spool, and the spool is sealingly matched with the valve seat on the condensed water discharge port. This trap has the following disadvantages. [0003] 1. The overall structure is asymmetr...

AI Technical Summary

Problems solved by technology

[0003] 1. The overall structure is asymmetrical, unbalanced eccentric structure combination, complex structure, complex mechanical relationship, and energy consumption

[0004] 2. The lever mechanism is to increase the closing thrust of the spool, but it makes the whole complex. The sealing pair that increases the thrust changes the movement track of the spool, which makes it difficult to achieve a high concentricity between the spool and the valve seat, resulting in line The contact sealing pair is difficult to achieve reliable sealing, leakage of steam, energy consumption

[0005] 3. The asymmetry of the fluid flow path increases the resistance, the eccentricity and complexity of the mechanism lead to an increase in resistance, and the energy consumption of the overall steam trap increases

[0006] 4. Due to the complex structure and asymmetry, the material consumption is large, the manufacturing process is complicated, and the manufacturing cost is increased
