Abstract
The utility model belongs to the field of special tool, and is applied to detect the airtightness of a welded junction of a welded stainless steel pipe. An airtightness rapid detection device for a welded junction of a stainless steel pipe provided by the utility model is characterized by mainly comprising an air inlet joint, an air inlet lock nut, an O-shaped sealing ring A, a plugging joint, a plugging lock nut and an O-shaped sealing ring B. When in application, one end of a welded stainless steel pipe is inserted into the air inlet lock nut, the O-shaped sealing ring A and the air inlet joint in sequence, and is in threaded connection with the air inlet lock nut through the air inlet joint so as to lock the O-shaped sealing ring A in the middle tightly on the pipe wall of the stainless steel pipe; the other end of the welded stainless steel pipe is connected with the plugging lock nut and the O-shaped sealing ring B, the plugging lock nut is inserted into the other end of the stainless steel pipe according to the operations and is tightly locked, then an air source is connected to detect whether the welded junction is leaking or not, and the device is disassembled by reverse operations according to the above method; and the detection is completed. Compared with the prior art, the airtightness rapid detection device has the beneficial effect that the device is not affected by the restrictions of length, shape and the like of the welded stainless steel pipe, and can detect the welding airtightness rapidly.
Description
Technical field
The utility model belongs to the specific purpose tool field, be applied to detect the stainless-steel tube welding after the weld bond impermeability use.
Background technology
Stainless-steel tube through welding after, impermeability need to detect in the weld bond place, uses other method of attachment to detect, and exists efficient low, waste large problem, use fast detecting stainless-steel tube weld bond impermeability device has simple to operately, efficient is high, and has reduced expense.
The utility model content
The utility model is intended to reduce costs for raising the efficiency, and overcomes the defective of prior art, provides a kind of fast detecting stainless steel pipes welding the rear bubble-tight instrument of weld bond.
Stainless-steel tube weld bond impermeability device for fast detecting is characterized in that, mainly by inlet suction port 1, and air inlet locknut 2, O RunddichtringO A 3 and shutoff joint 4, shutoff locknut 5, O RunddichtringO B 6 forms.During application, stainless-steel tube one end that welding is good is packed in air inlet locknut 2, and the O RunddichtringO A 3 that then packs into reinstalls inlet suction port 1, and the O RunddichtringO that is threaded the centre by inlet suction port 1 and air inlet locknut 2 is locked on the tube wall of stainless-steel tube; The other end shutoff locknut 5 of the stainless-steel tube that welding is good, O RunddichtringO B 6, shutoff joint 4 are packed into by aforesaid operations and are locked in other end stainless-steel tube, and then connect source of the gas and detect weld bond and whether leak gas, then by above method contrary operation dismounting; Complete detection.
Compared with prior art, the beneficial effects of the utility model are, the stainless-steel tube length after not welded, and the restriction of shape etc. all can its welding airtightness of fast detecting.
Description of drawings
