Embodiment Construction

[0023] see figure 1 , figure 2 , The invention is used for pressure detection of expansion joints, elbows, tees, straight blow pipes and other pipeline components of the blast furnace air supply pipeline system. The invention comprises a base 1, a bottom sealing seat 2, an upper opening sealing device and a side opening sealing device. The pipeline component to be detected is placed on the bottom sealing seat, and the lower port of the pipeline component to be detected is sealed by the bottom sealing seat. The bottom sealing seat is fixed on the base by bolts, and the bottom sealing seat can be replaced according to the requirements of the testing pipeline components. The compressed air pipe 3 is connected to the bottom sealing seat through the base. Mouth seal.

[0024] still refer to figure 1 , figure 2 , the upper port sealing device is used to seal the upper port of the pipeline component to be detected, and at the same time play a role in pressing the detection pip...

Abstract

A blast furnace air supply system pipeline component pressure detector, including a base, a bottom sealing seat, an upper opening sealing device and a side opening sealing device, the bottom sealing seat is fixed on the base, the compressed air pipe is connected to the bottom sealing seat, and the bottom sealing seat is There is a lower sealing gasket; the upper sealing device includes a beam, an upper sealing mechanism and the first and second support stands supporting the beam, the upper sealing mechanism is assembled on the beam, and the upper sealing mechanism is provided with an upper sealing cover The side port sealing device includes a side seal mechanism and a side seal height adjustment mechanism, the side seal height adjustment mechanism is connected to the side seal mechanism, and the side seal cover of the side seal mechanism seals the side port of the measured pipeline component. The present invention can conveniently and quickly complete the pressure test of various pipe components of different specifications, such as expansion joints, elbows, tees, and straight blow pipes, which are commonly used in the blast furnace air supply piping system, greatly reducing the detection operation time and improving the detection results. reliability and reduce labor intensity.

Description

technical field [0001] The invention relates to a pressure test device, in particular to a device for pressure detection of expansion joints, elbows, tees, straight blow pipes and other pipeline components in the blast furnace air supply system. Background technique [0002] The blast furnace air supply pipeline system sends hot air with a temperature of about 1450°C and a pressure of about 0.5MPa into the blast furnace hearth. The blast furnace air supply pipeline system includes various pipeline components such as pipelines, expansion joints, elbows, tees, straight blow pipes, etc. The above-mentioned pipeline components work under harsh working conditions, and the pressure test before putting into use is a very important inspection item , requires the manufacturer to carry out corresponding pressure tests on the pipeline components. The expansion joints, elbows, tees, straight blow pipes, etc. of the blast furnace air supply piping system are of various shapes. Port til...
