A marine lever float type steam trap

Abstract

The invention provides a marine lever float type steam trap, comprising: a bonnet with a floating ball inside and a lever assembly driven by the float; a valve body fixedly connected to the bonnet, and a The first and second cavity channels, the condensed water and uncondensed steam in the ship steam pipeline enter the valve cover from the first cavity channel, and the condensed water in the valve cover is discharged from the second cavity channel; the drainage assembly, It is arranged between the valve cover and the valve seat, and the drainage assembly is driven by the lever assembly to control the discharge of condensed water in the valve cover to the second cavity channel; the top of the exhaust assembly is arranged inside the valve cover, and the bottom of the exhaust assembly The pierced valve body is located in the second cavity channel. When the temperature of the uncondensed steam in the bonnet is lower than the first temperature threshold, the steam in the bonnet will be discharged to the second cavity channel through the exhaust assembly. The temperature of the uncondensed steam is higher than the first temperature threshold, and the steam is prevented from being exhausted to the channel of the second cavity through the exhaust assembly.

Description

technical field [0001] The invention relates to the field of marine valves, in particular to a marine lever float type drain valve. Background technique [0002] There are usually some large-scale heating equipment installed in the ship, and corresponding steam traps are usually installed in the steam pipeline of these heating equipment. The main function of the steam trap is to block the discharge of high-temperature steam in the pipeline and automatically discharge the condensed water in the pipeline. In some application scenarios, when the temperature of the non-condensable steam in the pipeline is lower than the first temperature threshold, the steam needs to be removed, and when the temperature of the non-condensable steam is higher than the first temperature threshold, the non-condensable steam needs to be blocked emissions. [0003] In the prior art, most steam traps used in high-temperature steam pipeline systems use heat-sensitive sealing valve seats, which cannot...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, most traps used in high-temperature steam pipeline systems use heat-sensitive sealing valve seats, which cannot automatically discharge non-condensable steam, let alone control steam discharge according to the temperature range of non-condensable steam

At the same time, the traps of the prior art still have the disadvantages of fixed drain temperature, small displacement, and the operation of the trap is affected by the degree of ship swaying, etc.
