To valve, check valve is arranged on the entrance point of intake tunnel.
The utility model has the advantages that：It is simple and practical, using very convenient, welded between adapter and equipment barrel
After the completion of can carry out weld seam detection, the problem of weld seam is exposed in advance, so as to be repaired to poor weld in advance,
Avoid situation about being repaired to poor weld again during equipment barrel late detection from occurring, it reduce weld seam
Rehabilitation cost, substantially reduces the making duration of equipment.
Brief description of the drawings
Fig. 1 is the structural representation of the detecting tool of weld seam between adapter described in the utility model and equipment barrel.
Specific embodiment
The utility model is described in further detail with preferred embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the detecting tool of the weld seam and equipment barrel between is taken over, including：Pressure testing roller 1, the diameter of pressure testing roller 1
Internal diameter with adapter 2 is adapted.One end of pressure testing roller 2 is fixedly connected with mounting blocks 3, and phase is provided with pressure testing roller 2 and mounting blocks 3
The intake tunnel 5 of connection.The outlet 51 of intake tunnel 5 is arranged on the side wall of pressure testing roller 1, and the import 52 of intake tunnel 5 is set
On mounting blocks 3, the import 52 of intake tunnel 5 is used to be connected with water pump.The length of pressure testing roller 1 is tried more than the length of adapter 2
Pressure roller 3 can be stretched in the equipment opening 41 in the equipment barrel 4 being connected with adapter 2 through adapter 2.Adapter 2 and equipment barrel 4
Between the both sides of weld seam 7 pressure testing roller 1 on be respectively provided with least one O-ring seal 11, O-ring seal 11 causes pressure testing roller
Sealed against each other between 1 and adapter 2 and between the inwall of pressure testing roller 1 and equipment opening 41, and intake tunnel 5 outlet 51 with weldering
There is no O-ring seal 11 to intercept between seam 7.The quantity of the O-ring seal 11 of the both sides of weld seam 7 can be set according to actual needs.
The pressure gauge connection 31 being connected with intake tunnel 5 is provided with mounting blocks 3, pressure gauge connection 31 is used to install pressure gauge.For
Be easily installed, form block ring 32 between the present embodiment pilot scale pressure roller 1 and mounting blocks 3, described block ring 32 can block exist
The outer end of adapter 2.Additionally, for the ease of controlling the keying of intake tunnel 5 and pressurize can be carried out, being provided with mounting blocks 3 unidirectional
Valve, check valve is arranged on the entrance point of intake tunnel 5.
Operation principle of the present utility model is：When needing the weld seam 7 between butt tube 2 and equipment barrel 4 to be detected,
