Composite steam hydrophobic valve for continuous drainage

Abstract

The invention relates to a composite steam hydrophobic valve for continuous drainage. The steam hydrophobic valve consists of a valve body and double valve cores, wherein the large valve core is mounted in a cavity of the valve body through a guide rail; when the valve cores float up, condensed water is drained by a condensed water outlet through a drainage hole of the guide rail; and a small hydrophobic function module is located in a normally open state when a large hydrophobic function module works, and can eliminate accumulated water in the stop of the hydrophobic valve. The hydrophobic valve can automatically adjust the dewatering quantity, can realize continuous dewatering, is low in steam leakage rate, and finally achieves the purpose of improving the system heat efficiency.

Description

Technical field [0001] The invention relates to a composite steam trap for continuous drainage, belonging to the technical field of valves. Background technique [0002] Steam is the secondary energy source in many industrial fields, and steam traps are important control valves that ensure the normal operation of the steam system and save energy. The function of the steam trap is to discharge the condensed water, gas and other non-condensable gases in the steam system as soon as possible, while preventing the leakage of steam to the maximum extent. [0003] At present, the commonly used traps have many shortcomings in terms of structure, technical performance, product quality and use functions. The main manifestations are: (1) Most of the drainage is mechanically used. When working under high load and harsh environment for a long time, the components are easy to damage. Greatly affect the service life; (2) The use of intermittent drainage, the valve core is subject to many impacts...

AI Technical Summary

Problems solved by technology

[0003] Currently commonly used steam traps have many deficiencies in terms of structure, technical performance, product quality, and use functions. The main manifestations are: (1) Most of them use mechanical drainage. When working under high load and harsh environments for a long time, the devices are easily damaged. Greatly affect the service life; (2) With intermittent drainage, the valve core is impacted many times, which is easy to cause wear and tear, and is easy to be accompanied by steam leakage, which not only affects production efficiency, but also wastes energy; (3) A little improper operation will cause As a result, the steam trap cannot be closed, resulting in a great waste of steam; (4) The failure rate is high, which increases the maintenance cost and the service life is short; (5) The condensate discharge cannot be automatically adjusted, and the process system cannot be guaranteed to be in the best working condition

[0004] Chinese patent 201320598170.5 provides an energy-saving steam trap that can adjust the discharge of condensed water, but its disadvantage is that the structure is relatively complicated
