To solve the above problems, the technical solution adopted by the present invention is that: the detection work of weld seam between adapter tube and equipment barrel
Dress, comprising: pressure testing roller, the diameter of pressure testing roller and the internal diameter of adapter tube are adapted, and one end of pressure testing roller is fixedly connected with mounting blocks, examination
The intake tunnel being connected is provided in pressure roller and mounting blocks, the outlet of intake tunnel is arranged on the side wall of pressure testing roller, water inlet
The import in channel is arranged on mounting blocks, and for being connected with water pump, the length of pressure testing roller is greater than adapter tube for the import of intake tunnel
Length, pressure testing roller can pass through adapter tube and stretch to and in the equipment opening in the equipment barrel that is connected of adapter tube, take over and device cartridge
One of O-ring seal is respectively provided at least on the pressure testing roller of weld seam two sides between body, O-ring seal makes pressure testing roller and connects
It is sealed against each other between pipe and between pressure testing roller and the inner wall of equipment opening, and there is no O between the outlet and weld seam of intake tunnel
The barrier of type sealing ring.
Further, it is above-mentioned adapter tube equipment barrel between weld seam detecting tool, wherein be provided on mounting blocks with
The pressure gauge connection that intake tunnel is connected, pressure gauge connection is for installing pressure gauge.
Further, between adapter tube above-mentioned and equipment barrel weld seam detecting tool, wherein pressure testing roller and mounting blocks it
Between formed block ring, the block ring energy block is in the outer end of adapter tube.
Further, the detecting tool above-mentioned for taking over the weld seam between equipment barrel, wherein list is provided on mounting blocks
To valve, check valve is mounted on the input end of intake tunnel.
The invention has the advantages that simple and practical in structure, use is very convenient, welds and completes between adapter tube and equipment barrel
After can carry out weld seam detection, will expose in advance the problem of weld seam, so as to be repaired in advance to poor weld, avoid
The case where repairing again to poor weld during equipment barrel late detection, it reduce the reparations of weld seam
Cost substantially reduces the production duration of equipment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the detecting tool of weld seam between adapter tube of the present invention and equipment barrel.
Specific embodiment
The following further describes the present invention in detail with reference to the accompanying drawings and preferred embodiments.
As shown in Figure 1, taking over the detecting tool of the weld seam between equipment barrel, comprising: pressure testing roller 1, the diameter of pressure testing roller 1
It is adapted with the internal diameter of adapter tube 2.One end of pressure testing roller 1 is fixedly connected with mounting blocks 3, is provided with phase in pressure testing roller 1 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 arranged
On mounting blocks 3, the import 52 of intake tunnel 5 with water pump for being connected.The length of pressure testing roller 1 is greater than the length of adapter tube 2, examination
Pressure roller 1 can pass through adapter tube 2 and stretch in the equipment opening 41 in the equipment barrel 4 being connected with adapter tube 2.Adapter tube 2 and equipment barrel 4
Between 7 two sides of weld seam pressure testing roller 1 on be respectively provided at least one of O-ring seal 11, O-ring seal 11 makes pressure testing roller
It is sealed against each other between 1 and adapter tube 2 and between pressure testing roller 1 and the inner wall of equipment opening 41, and the outlet 51 of intake tunnel 5 and weldering
There is no the barrier of O-ring seal 11 between seam 7.The quantity of the O-ring seal 11 of 7 two sides of weld seam can be set according to actual needs.
The pressure gauge connection 31 being connected with intake tunnel 5 is provided on mounting blocks 3, pressure gauge connection 31 is for installing pressure gauge.For
Be easily installed, form block ring 32 between the present embodiment pilot scale pressure roller 1 and mounting blocks 3, the block ring 32 can block exist
The outer end of adapter tube 2.In addition, being provided on mounting blocks 3 unidirectional for the ease of controlling the opening and closing of intake tunnel 5 and can be carried out pressure maintaining
Valve, check valve are mounted on the input end of intake tunnel 5.
The operation principle of the present invention is that: when needing the weld seam 7 between butt tube 2 and equipment barrel 4 to be detected, first will
Pressure testing roller 1 passes through adapter tube 2 and stretches in the equipment opening 41 being connected with adapter tube 2, up to 32 block of block ring on mounting blocks 3
In the outer end of adapter tube 2, pressure gauge is then loaded on pressure gauge connection 31, then connects water in the import 52 of intake tunnel 5
Pump, water is constantly delivered in intake tunnel 5 by water pump, the water in intake tunnel 5 can then be entered to by outlet 51 pressure testing roller 1 with
In gap between adapter tube 2 and equipment opening 41, when the pressure on pressure gauge reaches setting value, switch off the pump and intake tunnel
Check valve on 5 carries out pressure maintaining, and pressure maintaining checks whether weld seam has leakage for a period of time afterwards, has leakage then to illustrate that weld seam is defective,
Ne-leakage then illustrates that the leakproofness of weld seam and intensity are all satisfied requirement.
The present invention has the advantages that simple and practical in structure, use is very convenient, welds between adapter tube 2 and equipment barrel 4
Weld seam detection can be carried out after the completion, will be exposed in advance the problem of weld seam, so as to be repaired in advance to poor weld,
The case where repairing again to poor weld during 4 late detection of equipment barrel is avoided, it reduce weld seams
Rehabilitation cost, substantially reduce the production duration of equipment.
