Abstract

The utility model relates to a coal gas valve case for user points, which is used for supplying mixed gas or coke oven gas to the user points of pipelines. The utility model is composed of a gas inlet pipe, a pressure reductor, a check valve, a flame arrester, a gas outlet pipe, a control valve, a bracket and a tank body, wherein, the pressure reductor is arranged on the gas inlet pipe, the gas inlet pipe is connected with one end of the check valve, the other end of the check valve is connected with the outlet of the flame arrester, the gas outlet pipe is connected with the inlet of the flame arrester, the control valve is arranged on a gas pipeline, the gas inlet pipe, the pressure reductor, the check valve, the flame arrester, the gas outlet pipe and the control valve are all arranged on the bracket, the bracket is fixed on the tank body, and the gas inlet pipe and the gas outlet pipe are respectively penetrated into the tank body from the upper end and penetrated out of the tank body from the lower end. The utility model has the advantages that the explosion accidents are prevented from occurrence, and the safety is guaranteed.

Description

Coal gas valve case for user area

The utility model is to put the utensil of use for each user on the mixed gas of industries such as metallurgy or the coke-stove gas pipeline.

According to the interrelated data retrieval, also there be not the Coal gas valve case for user area identical at present with the utility model structure.When using coal gas in present smelting, the continuous casting process at metallurgy industry, all be on the house steward of gaspipe line, to connect an arm, on arm, adorn a decompressor, the export pipeline of decompressor is directly for using on smelting or the continuous casting process, its deficiency is if there is tempering to produce in the gaspipe line, accident such as then easily blast makes the person and device security can not get guarantee.

The purpose of this utility model is to overcome at present the deficiency of using coal gas on the smelting of metallurgy industry and continuous casting process, provides a kind of accident that can prevent effectively to take place, and guarantees the Coal gas valve case for user area of the person and device security.

The purpose of this utility model is achieved through the following technical solutions.Coal gas valve case for user area is made up of suction tude, decompressor, safety check, flame trap, steam outlet pipe, control valve, support and casing, decompressor is contained on the admission line, one end of suction tude and safety check links, the other end of safety check and the outlet of flame trap link, the import of steam outlet pipe and flame trap links, control valve is contained on the outlet pipe, suction tude, decompressor, safety check, flame trap, steam outlet pipe and control valve all are contained on the support, support is fixed in the casing, suction tude penetrates from the upper end of casing, and steam outlet pipe passes from the lower end of nationality body.Support is made with the angle steel welding.Casing is made with steel plate, on the cabinet door with decompressor on the corresponding position of pressure gauge on the observation window of clear glass is housed.

Use on the utility model and the present metallurgy industry, coal gas is directly compared for smelting or continuous casting process use from the decompressor outlet end, owing to adorned safety check and flame trap, therefore in use produce if any tempering, flame trap can extinguish tempering, as tempering not being extinguished, then safety check can stop tempering live, it is not returned in the suction tude go, thereby have the generation that can prevent accidents such as exploding effectively, guarantee the advantage of the safety of the person and equipment.

Accompanying drawing 1 is a structural representation of the present utility model.1--suction tude among the figure; The 2--decompressor; The 3--flame trap; The 4--steam outlet pipe; The 5--support; The 6--control valve; The 7--safety check; The 8--casing; The 9--chamber door; The 10--observation window.

Below in conjunction with description of drawings use condition of the present utility model:

The flange of suction tude 1 upper end links to each other with the flange on the gas main, make coal gas enter the front end of suction tude 1 from house steward, after the decompression of decompressor 2, enter the rear end of suction tude 1, enter the front end of steam outlet pipe 4 through safety check 7 flame trap 3 of flowing through then, enter the back segment of steam outlet pipe 4 again through control valve 6, directly enter after the outlet side of steam outlet pipe 4 and flexible pipe join in smelting or the continuous casting process and use.When in using, tempering occurring on the pipeline, the control valve 6 of tempering in steam outlet pipe 4 and outlet pipe enters flame trap 3, this moment, tempering was extinguished in flame trap 3 meetings, even can not extinguish, safety check 7 also can stop tempering live, it is no longer entered in the air inlet pipeline 1 go, thereby prevent the generation of explosive accident effectively, guarantee the safety of the person and equipment.
