The device is provided with the high-order elbow through the adding pipeline, so that when the liquid ammonia pipeline generates negative pressure, ammonia water flows back and cannot reach the highest point to cross the high-order elbow, the effect of breaking vacuum and preventing backflow is achieved, and the safe and effective operation of the system is effectively ensured.
Description
Technical Field
The utility model relates to the field of ammonia water preparation, in particular to a device for breaking vacuum by adding ammonia into a system.
Background
In the existing ammonia water preparation process, the ammonia water is very easy to be dissolved in water to generate vacuum, so that the ammonia water can flow back to an ammonia pipeline system, and the system is threatened; the added check valve can not completely block the medium backflow, can not effectively ensure the safe and effective operation of the system, and the existing check valve can play a role in safety isolation, but has the characteristics of high system resistance and poor tightness when being closed under the ammonia adding condition of the system, and can not effectively prevent ammonia water from entering a liquid ammonia pipeline system through the check valve and other valves; for this purpose, a device for breaking vacuum by adding ammonia is provided.
Disclosure of Invention
The utility model aims at overcoming the defects of the prior art and provides a device for ammonia adding and vacuum breaking of a system, so as to solve the problems of the prior art.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a broken vacuum device of system ammonia, includes ammonia valve, first riser, elbow, ammonia cask, liquid ammonia are responsible for and second riser, be connected with the second riser on the ammonia cask, the top of second riser is connected with the elbow, the one end of elbow is connected with first riser, install the ammonia valve on the first riser, the liquid ammonia is responsible for is installed to the one end of first riser.
As a preferred embodiment of the present utility model, the elbow is welded to the first riser and the second riser.
As a preferable technical scheme of the utility model, the first vertical pipe is welded with the liquid ammonia main pipe.
As a preferred embodiment of the present utility model, the ammonia valve is mounted on the first and second risers by means of a connecting flange and a gasket and bolts.
The beneficial effects of the utility model are as follows: the device is provided with the high-order elbow through the adding pipeline, so that when the liquid ammonia pipeline generates negative pressure, ammonia water flows back and cannot reach the highest point to cross the high-order elbow, the effect of breaking vacuum and preventing backflow is achieved, and the safe and effective operation of the system is effectively ensured.
The device utilizes the principle that the water column in the pipeline has the highest height under the vacuum condition, and prevents the water column in the pipeline from crossing the elbow by arranging the pipeline with a certain height and the elbow, thereby achieving the purpose of breaking vacuum and preventing backflow and ensuring the safe operation of the ammonia system pipeline.
The device is composed of a pipeline, an elbow and the like; compared with the additionally arranged check valve, the device has the advantages of simple structure, convenient later maintenance, low investment cost, safety, reliability, long service life and the like.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
In the figure: the ammonia adding valve 1, the first vertical pipe 2, the elbow 3, the ammonia water barrel 4, the liquid ammonia main pipe 5 and the second vertical pipe 6.
Detailed Description
The preferred embodiments of the present utility model will be described in detail below with reference to the attached drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.
Examples: referring to fig. 1, a device for breaking vacuum by adding ammonia in a system comprises an ammonia adding valve 1, a first vertical pipe 2, an elbow 3, an ammonia barrel 4, a liquid ammonia main pipe 5 and a second vertical pipe 6, wherein the ammonia barrel 4 is connected with the second vertical pipe 6, the top of the second vertical pipe 6 is connected with the elbow 3, one end of the elbow 3 is connected with the first vertical pipe 2, the ammonia adding valve 1 is installed on the first vertical pipe 2, and the liquid ammonia main pipe 5 is installed at one end of the first vertical pipe 2.
