Continuously drained steam trap valve

Abstract

The invention relates to a continuously drained steam trap valve. The steam trap valve comprises a valve body and a valve element, wherein the valve element is arranged in the cavity of the valve body through a guide rail, when the valve element floats, condensed water is drained out through a condensed water outlet by passing through a drain hole of the guide rail, the dewatering amount is automatically adjusted, continuous dewatering can be realized, the leakage rate of steam is low, and finally the aim of improving the system heat efficiency is achieved.

Description

technical field [0001] The invention relates to a continuous drainage steam trap, which belongs to the technical field of valves. Background technique [0002] Steam is a secondary energy source in many industrial fields, and steam traps are important control valves to ensure the normal operation of steam systems 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, and at the same time prevent the leakage of steam to the greatest extent. [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 ea...

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
