Background technology
At present titanium steel, zirconium titanium steel explode in the compound container made; Because multiple layer side titanium and zirconium can't be implemented mutual fusion welding with the carbon steel (or stainless steel) of basic unit; The welding of the vertical girth joint of container is being welded to each other of basic unit and basic unit's side, being welded to each other of multiple layer and multiple layer side (multiple layer side adopt be joint strip joint welding welded structure).Under the operation operating mode of HTHP, circular gap property, because the sheet metal thickness of multiple layer side is thinner, the intensity of the weld seam of joint strip is lower, in this case toward back and forth the joint strip or the joint strip weld seam of layer side are easily damaged.The Korrosionsmedium of internal tank will leak in the gap of multiple laminating bar and basic unit's weld seam and go, and often the material of basic unit's side does not possess good corrosion resistance, and the time that medium stops in the gap, longer weld decay to multiple layer and multiple layer was serious more.The medium that passes through the discovery leakage is early inferred the damage of joint strip or joint strip weld seam, for maintenance tries to gain time precious to one just extremely urgent.And chemical industry basically the time continuity produce (and the part price of chemical products is comparatively expensive), the maintenance of can not at once stopping again after often finding outward to leak is for the transfer that the material of device interior ends strives for that certain blink, also ten minutes was important.
Summary of the invention
The purpose of the utility model be to existing titanium steel, zirconium titanium steel explosive clad plate container made, vertical girth joint joint strip of multiple layer side and joint strip weld seam damage the problem of leakage easily, designs a kind of relatively rationally multiple layer weld seam and hunt leak and chew modular construction.Can chew through leak detection and detect multiple layer side joint strip and joint strip weld seam and whether damage can also oppositely the ventilate welding quality of multiple laminating bar of inspection and filler strip weld seam of leakage.
The technical scheme of the utility model is:
Structure is chewed in the multiple layer weld seam leak detection of infusibility active metal, comprisesLeak detection is chewed, is hunted leak and chew skirt 3 and protective casing 2 is chewed in leak detection, and it is the round steel pipe that are provided with internal thread hole that leak detection chews 4, and leak detection is chewed and chewed skirt with leak detection and is connected, and the diameter of chewing protective casing 2 of hunting leak is chewed skirt greater than leak detection and is placed in the outside of hunting leak and chewing skirt.Leak detection chew length that protective casing and leak detection chew skirt greater than
The multiple layer of metal outsideThe thickness of heat-insulation layer.
Leak detection is chewed, is hunted leak and chew the outside surface that skirt 3 is arranged at composite plate 6 basic unit's sides; Corresponding basic unit side weld 12 and composite plate filler strip 8 bore system one minor diameter through hole; Make the gap and the atmosphere of 8 of composite plate multiple layer side joint strip 11 and composite plate filler strips, leak detection is chewed and is connected in this gap.
Under the multiple layer situation that then joint strip 11 or joint strip weld seam 10 damage, the medium of internal tank under the effect of interior pressure through leak detection chew 4 leak to container the outside, chew through leak detection and to come to light.
The beneficial effect of the utility model: the utility model helps under the prerequisite that the multiple laminating bar of composite plate or joint strip weld seam are damaging; Chew the medium of finding internal tank through leak detection and under the effect of interior pressure, leak to the damage that inner joint strip of composite plate or joint strip weld seam were found and then inferred to external container timely, can also oppositely ventilate to the gap of the multiple laminating bar of composite plate and basic unit's weld seam through the threaded hole configuring external screwed pipe assembly that leak detection is chewed and check the welding quality of multiple laminating bar and filler strip weld seam.
The utility model is simple in structure; Make things convenient for a large amount of deposits in early stage of device fabrication to make the stock, be easy to realize that effect is fairly obvious; It is less to take up room; Basically do not receive the restriction of installation position and angle, solved titanium steel, zirconium titanium steel multiple layer side joint strip and joint strip weld seam damage and leak the difficult problem of back inspection, for on-call maintenance wins the quality time.
