Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1-4, a compound steel pipe crack detection equipment, includes air pump 1 and ring body 8, both sides all are connected with gasbag 10 through the pregroove veneer in the ring body 8, and gasbag 10 one end is provided with intake pipe 4, the end of giving vent to anger in 1 one side of air pump has three-way valve 2 through the pipe connection, and 2 one side bottoms of three-way valve give vent to anger the end suit and fill in trachea 4, 2 one side tops of three-way valve are given vent to anger the end suit and are equipped with gas- supply pipe 3, and 3 one end connection ring bodies 8 of gas-supply pipe.
Wherein, the peripheral veneer of 3 one ends of gas-supply pipe is connected with circular locating plate 13, and 13 one side of circular locating plate veneer is connected with the sealing rubber circle 12 corresponding with gas- supply pipe 3, 8 inside surface of ring body has been seted up and has been detected groove 11, and circular locating plate 13 and sealing rubber circle 12 all are located and detect groove 11.
In this embodiment, as shown in fig. 1, 2 and 4, the gas pipe 3 can be drawn in the ring body 8, so that the positions of the sealing rubber ring 12 and the circular positioning plate 13 can be changed.
Wherein, the other end of the air bag 10 is provided with an exhaust pipe 5, and the exhaust pipe 5 is provided with a valve 6.
In this embodiment, as shown in fig. 1, a person opens the valve 6 to allow the gas in the airbag 10 to be discharged through the exhaust pipe 5.
