Abstract

The invention relates to a single body pressure testing tool, a single body pressure testing tool combination and a pressure testing method for blast furnace cooling equipment. According to the technical scheme, the single body pressure testing tool for the blast furnace cooling equipment comprises a screw and a rubber hose sleeved outside the screw, and a nut is arranged at one end of the rubber hose and is in threaded connection with the screw which can enable the nut to press the rubber hose if the screw rotates. The single body pressure testing tool combination for the blast furnace cooling equipment is characterized in that two single bodies are connected together through the pressure testing hose. A method for testing pressure of a cooling wall single body is characterized by comprising the following steps of: filling water in the cooling wall single body; sealing in a series-connection manner; exhausting; closing an exhaust opening; and boosting pressure to detect leakage. By the technical scheme, the single body pressure testing tool for the blast furnace cooling equipment has the advantages that welding is not required, connection speed is high, the single body pressure testing tool can be detached after pressure testing is finished and can be used repeatedly, the rubber hose can be replaced after the single body pressure testing tool is used for 30 times, a cooling wall can be provided with tubes normally after the single body pressure testing tool is detached, ports are not required to be re-treated, cost is saved, and construction period is short.

Description

Technical field: [0001] The invention relates to a single pressure test tooling, combination and pressure test method of blast furnace cooling equipment. Background technique: [0002] The blast furnace cooling equipment is the equipment with the largest number and the heaviest weight in the blast furnace body. It is mainly installed inside the furnace body to cool the furnace shell. The cooling wall water pipe is made of 10# thick-walled seamless pipe. Before stave installation and construction, the most important job of the construction unit is to ensure that the quality of each stave is qualified, and how to ensure that the cooling equipment on site is a qualified product. The specification stipulates that before installation, the tightness test and full flow test should be carried out block by block according to the provisions of the equipment technical documents. Currently there is no unified equipment and method for pressure testing. Invention content: [0003] P...
