Coke oven heating gas pipeline pressure test device and method

Abstract

The invention discloses a pressure testing device and method for a coke oven heating gas pipeline. The pressure testing device comprises a jack (1), a pressure measuring scale (9), a steel fixing frame (3), an air distribution cylinder (4) and an inflation sleeve (10), and is characterized in that: the jack (1) is a commercially available RCS-series thin hydraulic jack; the pressure indicating measuring scale (9) is a pressure indicating measuring scale which is provided with graduations and is 2.1-2.2 meters in length; the steel fixing frame (3) is formed by welding a carrier rod, an upright post and a bottom plate; the bottom plate is provided with an air inflating hole (7); the air distribution cylinder (4) is an airtight steel air drum; one side of the air distribution cylinder (4) is provided with an air inflating hole, and the other side of the air distribution cylinder (4) is provided with a plurality of air outlet holes; the air inflating hole and the air outlet holes are provided with ball valve switches respectively; and the inflation sleeve (10) is an ordinary bicycle inflation sleeve for supplying air to the air distribution cylinder (4). The pressure testing device for the coke oven heating gas pipeline disclosed by the invention has the advantages of increase in the pressurizing speed and saving in labor force investment due to the application of the hydraulic jack.

Description

technical field [0001] The invention relates to a gas pipeline construction technology in the metallurgical coking industry, in particular to a coke oven heating gas pipeline pressure testing device and method. Background technique [0002] During the construction of the coke oven process pipeline, since a large number of orifice boxes and cocks in the coke oven gas pipeline system need to be pressure tested one by one, and the above equipment is used for coke oven and blast furnace gas pipelines, the processing requirements for equipment and product protection requirements Once this part of the equipment leaks, it will cause the leakage of blast furnace gas and coke oven gas, which will have serious consequences for personal safety and production. At present, the on-site pressure test of the coke oven gas pipeline system adopts the traditional pressure test method, and the bolt blind plate seal pressure test method is used on both sides of the pressure test equipment such a...

Problems solved by technology

[0002] During the construction of the coke oven process pipeline, since a large number of orifice boxes and cocks in the coke oven gas pipeline system need to be pressure tested one by one, and the above equipment is used for coke oven and blast furnace gas pipelines, the processing requirements for equipment and product protection requirements Extremely high, once this part of the equipment leaks, it will cause the leakage of blast furnace gas and coke oven gas, which will have serious consequences for personal safety and production

At present, the on-site pressure test of the coke oven gas pipeline system adopts the traditional pressure test method, and the bolt blind plate seal pressure test method is used on both sides of the pressure test equipment such as cocks and orifice boxes, which is cumbersome to operate

Therefore, the traditional pressure test technology has the disadvantages of labor-intensive, time-consuming, and poor efficiency. For example, human operation has a great impact on the quality of the pressure test, and often a little bit of operation error has to be completely dismantled and re-tested; the accessories used for the pressure test are worn out. Large; the success rate of the pressure test is low; the test takes a long time, and blind plates of multiple sizes need to be processed, etc.

[0003] Therefore there is above-mentioned inconvenience and problem in the pressure test device of known coke oven gas pipeline system
