Bi-directional water drain valve structure easy in adjustment of flow

Abstract

The invention relates to the technical field of water drain valves and discloses a bi-directional water drain valve structure easy in adjustment of a flow. The bi-directional water drain valve structure easy in adjustment of the flow comprises a valve body, a sealing bolt in threaded connection with one side of the bottom of the valve body in a sleeved manner, a fixed sleeve and a second fixed sleeve; the fixed sleeve and the second fixed sleeve are fixedly connected to the interior of the valve body in the sleeved manner; a first sealing cover is in threaded connection to threads on the top of the fixed sleeve in the sleeved manner; an adjusting mechanism is fixedly connected to the interior of the first sealing cover in the sleeved manner; a filter screen is installed between the fixed sleeve and the second fixed sleeve in the sleeved manner; and the second fixed sleeve is movably provided with a lifting mechanism arranged on the inner side of the filter screen inside in the sleevedmanner. For the bi-directional water drain valve structure in adjustment of the flow, through matching use of the fixed sleeve, the second fixed sleeve, a filter screen and the second sealing cover, amemory alloy spring can be arranged at a lower position of the valve body; when hot water flows into the valve body, the memory alloy spring can be preferentially in contact with the hot water to jack up a spherical valve with thermal expansion; and the spherical valve and the water outlet hole are in contact sealing, and closing of the spherical valve is achieved in time.

Description

technical field [0001] The invention relates to the technical field of steam traps, in particular to a two-way steam trap structure with easy flow adjustment. Background technique [0002] Steam traps are called steam traps, also called automatic drains or condensate drains, which are divided into steam system use and gas system use. The steam trap is installed at the end of the steam-heated pipeline, and its function is to continuously discharge the condensed water in the steam-heated pipeline to the outside of the pipeline. [0003] Some existing steam traps are not equipped with a flow adjustment mechanism, which makes it inconvenient to adjust the discharge flow of condensed water. Moreover, the memory alloy spring installed inside the valve body is at a higher position inside the trap. When hot water flows into the valve body, The memory alloy spring cannot contact hot water first, part of the heat of the hot water will be absorbed by the valve body, the memory alloy s...

Problems solved by technology

[0003] Some existing steam traps are not equipped with a flow adjustment mechanism, which makes it inconvenient to adjust the discharge flow of condensed water. Moreover, the memory alloy spring installed inside the valve body is at a higher position inside the trap. When hot water flows into the valve body, The memory alloy spring cannot contact hot water first, part of the heat of the hot water will be absorbed by the valve body, the memory alloy spring cannot be heated and expanded in time, and the ball valve is closed, resulting in part of the hot water being discharged, and the closing of the ball valve has a delay
