Sealing clamp, described sealing clamp include left seal head and right seal head, are provided with described left seal head
Pressure-air interface；Sealing locating slot and rubber seal, described sealing positioning are provided with described sealing clamp
Groove is uniformly arranged on the both sides hypotenuse of sealing clamp, and described rubber seal is arranged on sealing locating slot；It is described
Boiler tube above be provided with diaphragm seal, the size of described diaphragm seal is consistent with the length of boiler tube.
As preferable technical scheme：Described sealing clamp includes column construction and pyramidal structure, a described left side
The column construction of seal head coordinates rotation through rotating hole on right baffle-plate, with right baffle-plate.
As preferable technical scheme：The column construction of described right seal head, which is arranged in right shell body, to be rotated.
As preferable technical scheme：Described sealing locating slot is of an L-shaped structure, and short side dimension is more than boiler tube wall thickness；Institute
The rubber seal stated is consistent with short side dimension.
The method that the utility model is coordinated using diaphragm seal with boiler tube can seal tube skin, be passed through gases at high pressure entrance
In pipe, heaving occurs in diaphragm seal, and illustrates that boiler tube is unqualified, improves the reliability of inspection.The device of boiler tube and sealed clamping it is close
Seal even closer, sealing clamp is suitable for the boiler tube of different length and different-diameter.Do not polluted in diaphragm seal seal process
The surfaces such as boiler tube endoporus, end face, reduce postorder drying process.Diaphragm seal is reusable, can save consumptive material, save people
Power, and automated production can be realized, drastically increase the operating efficiency of boiler tube inspection.
