Abstract
The utility model provides an operating system of the steam heating coil of a cargo vessel, which comprises an operating part prior to feeding of steam into the heating coil and an operating part after discharging of steam by the heating coil. The operating part after discharging of steam by the heating coil mainly comprises a steam trap valve, the steam trap valve consists of a steam trap, cut-off valves and pipelines, one cut-off valve is arranged respectively in front of the steam trap and behind the steam trap, a bypass pipe is connected in the front of the front cut-off valve and behind the rear cut-off valve, and a bypass cut-off valve is arranged on the bypass pipe. When the steam trap has no failure, the user can open the front cut-off valve and the rear cut-off valve and close the bypass valve. When the steam trap has the failure and needs repair, the user can close the front cut-off valve and the rear cut-off valve and open the bypass valve, so that the coil heating system can operate normally and the heating of the coil heating system can not be influenced. Simultaneously, with the additional cut-off check valve, no steam back-flowing accident can occur in any case. The utility model not only can be used on the vessel, but also can be in various process steam heating systems in the power plant, the petroleum field, the chemical field and the like.
Description
Technical field
The utility model relates to a kind of Cargo Oil ship steam heating coil operating system.
Background technology
Cargo heating coils operating system is the drain valve group system of large ship special use; Complete cargo heating coils system is formed by steam pipeline system and condensate line system in combination, its effect is the steam input drain valve group with boats and ships main steam header road, under the effect of drain valve group, the condensate water in the steam enters boats and ships condensate water trunk line then.Thereby ensured the normal operation of boats and ships steam supply pipeline, its maximum operating temperature is 260 ℃.
Cargo Oil ship steam heating coil operating system, the originally domestic space state that is in mainly relies on from Korea S's import.Korean Products needs halt system heating place under repair or replacing, inconvenience after vapor and water separator damages.
Summary of the invention
The utility model is at the deficiencies in the prior art, proposes a kind ofly to need not the halt system heating and just can overhaul, change Cargo Oil ship steam heating coil operating system easily to vapor and water separator.
The purpose of this utility model is achieved through the following technical solutions:
Cargo Oil ship steam heating coil operating system of the present utility model, comprise steam line, heating coil and condensate water pipe, and first screw down nonreturn valve, first shutoff valve of one group of parallel connection and the drain valve group of one group of parallel connection, wherein, first screw down nonreturn valve is arranged on the leading portion of steam line, first shutoff valve is arranged on the steam line back segment, the exit end of this first shutoff valve links to each other with an end of heating coil, the drain valve group is arranged on the condensate water pipe, the arrival end of this drain valve group links to each other with the other end of heating coil, it is characterized in that: described drain valve group is by vapor and water separator, shutoff valve and pipeline are formed, preceding shutoff valve is set before vapor and water separator, the back shutoff valve is set behind vapor and water separator, before preceding shutoff valve with behind the shutoff valve of back, is connected bypass pipe, the bypass cutoff valve is set on bypass pipe.
Further, the utility model increases a screw down nonreturn valve again in the bypass pipe back, prevents that steam from flowing backwards.
By above scheme, can realize following useful technique effect:
When the vapor and water separator trouble free, shutoff valve before and after opening is closed bypass disc; When the vapor and water separator et out of order need overhaul, shutoff valve before and after closing was opened the work as usual of bypass disc, coil pipe heating system, does not influence its heating.Increased screw down nonreturn valve simultaneously, steam refluence accident can take place in no instance.
