Problems solved by technology
[0003] The currently used steam traps are found to have some deficiencies during use. The steam traps need to be opened and closed quickly in the working process to achieve drainage and steam resistance, and the flow characteristics of the medium cannot be controlled and adjusted. When the medium flows through When the valve body is damaged, cavitation is caused, accompanied by huge noise, which brings huge economic losses and serious environmental noise pollution

The invention relates to a steam trap, in particular to a novel inverted-bucket type adjustable pilot great-drainage steam trap. The novel inverted-bucket type adjustable pilot great-drainage steam trap comprises a valve body and a valve seat, a main valve body (15) is respectively provided with a pilot valve body (6) and an upper flange (21), the lower end of the main valve body is provided witha lower flange (18), an inner cavity of the main valve body (15) is provided with a main valve seat (13), an inverted-bucket component (23) is mounted in the cavity of the pilot valve body (6), an upper cavity of the main valve body (15) is sequentially provided with a muffler sleeve component (35) and a piston sleeve (12), a lower cavity of the main valve body (15) is provided with a throttle sleeve (16), and a main valve core (14) respectively penetrates through central holes of the throttle sleeve (16), the muffler sleeve component (35) and a piston (28). By adopting the novel throttle sleeve structure, the invention adjusts the medium flow characteristic and improves the pressure drop ratio by adopting the novel muffler sleeve component through reasonable keyhole layout and fenestration to take the action of silencing and reducing noise and has the advantages of high working pressure, great discharge, stable performance, long service life, low steam leakage rate and high energy-saving efficiency.
Description
technical field [0001] The invention relates to a steam trap, in particular to a novel inverted bucket adjustable pilot super large displacement steam trap. Background technique [0002] As an important secondary energy source, steam has been widely used in various industries, such as petroleum, chemical industry, textile, medicine, food and other industries. In the whole steam system, in order to improve the thermal efficiency of steam use, steam traps are widely used. The function of the steam trap is to automatically remove condensed water, air and non-condensable gas on the steam pipe network or steam heating equipment, prevent steam leakage and improve thermal efficiency. There are many types of steam traps, which mainly rely on the heat (temperature), liquid level, and flow rate of the absorption medium as the power to realize the function of the steam trap. With the development of science and technology and the expansion of industrial scale, industrial production ha...
