Description
Technical Field
The utility model relates to a connect pressure testing device, concretely relates to pipe screen pressure testing frock.
Background
The hydraulic test is required to be carried out independently before the tube panel and the water-cooled wall are installed after the tube panel and the water-cooled wall are manufactured, and the joint of the tube panel and the water-cooled wall header is a welded joint, so that the method cannot be applied to a flange cover plugging pressure test method.
Disclosure of Invention
The utility model provides a pipe screen pressure test tool, which solves the technical problems that the cutting slag falls into the header in the process of cutting off the pressure test end socket by the conventional pressure test method and the service performance of the pipe screen and the water wall is affected; the pressure testing device is suitable for pressure testing of boiler tube panels and water-cooled wall header joints, particularly after the boiler tube panels and the water-cooled wall header joints are manufactured, the tube panels and the water-cooled wall header joints are subjected to plugging pressure testing, and a pressure testing end socket does not need to be welded, pressure testing allowance is cut off, and a groove is polished during hydraulic pressure testing, so that the possibility that cutting slag falls into the header in the process of cutting off the pressure testing end socket by a conventional pressure testing method is avoided, and the service performance of the tube panels and the water-cooled wall is ensured.
For solving the technical problem, the utility model discloses the technical scheme who adopts does: the device comprises two U-shaped header side supporting plates, wherein two end parts of each header side supporting plate are detachably connected with connecting plates respectively, the lower ends of all the connecting plates are detachably connected with a gland together through header joints, the middle part of one side, close to the header joints, of the gland is welded with a protective cylinder, a tendon sealing gasket is arranged in the protective cylinder, the middle part of the gland is connected with a pressure test tube which penetrates through a gland body, one end of the pressure test tube extends into the tendon sealing gasket, and the other end of the pressure test tube is connected with a pressure gauge seat; the gland is connected with the connecting plate through a compression nut and a compression stud.
The working principle is as follows: the header backup pad passes the convection tube clearance and supports in the header convection tube side to detachable is connected with the connecting plate, compresses tightly header joint, cowhells pad with the gland through the hold-down stud, realizes tube panel, water-cooling wall shutoff, and gland joint side welding protects a section of thick bamboo, plays the guard action to the pressure testing process, and this pressure testing frock adopts the bolt-up, convenient operation, stable in structure.
Compared with the prior art the utility model discloses following beneficial effect has:
the utility model discloses the frock adopts the bolt-up, convenient operation, stable in structure, extensive applicability, and sealing performance is high, effectively improves production efficiency, avoids conventional pressure testing method to cut off the possibility that the pressure testing head in-process cut the sediment and fall into the header, guarantees tube panel, water-cooling wall performance.
Drawings
Fig. 1 is the utility model discloses the structural schematic diagram of tube panel pressure testing frock.
Fig. 2 is a view taken along direction a of fig. 1.
The figures are labeled as follows:
1-a header side supporting plate, 2-a connecting plate, 3-a protective cylinder, 4-a gland, 5-a compression nut, 6-a compression stud, 7-a connection nut, 8-a connection bolt, 9-a cowhells sealing gasket and 10-a pressure gauge seat.
Detailed Description
The present invention will be further described with reference to the following specific examples.
Examples
As shown in fig. 1 and 2, a pipe screen pressure test tool comprises two U-shaped header side support plates 1, wherein two end parts of each header side support plate 1 are detachably connected with a connecting plate 2, the lower ends of all the connecting plates 2 are detachably connected with a gland 4 through a header joint, the middle part of one side, close to the header joint, of the gland 4 is welded with a protective cylinder 3, a tendon sealing gasket 9 is arranged in the protective cylinder 3, the middle part of the gland 4 is connected with a pressure test pipe which penetrates through a gland 4 body and one end of which extends into the tendon sealing gasket 9, and the other end of the pressure test pipe is connected with a pressure gauge stand 10; the gland 4 is connected with the connecting plate 2 through a compression nut 5 and a compression stud 6.
Further, the header side support plate 1 is connected with the connection plate 2 through a connection nut 7 and a connection bolt 8.
Further, the thickness of connecting plate 2 is unanimous with the thickness of header side backup pad 1, the lower extreme and the header joint rigid coupling of connecting plate 2, the thread groove that is used for being connected with gland 4 is seted up to the one end of being connected of header joint and gland 4.
Further, header collateral branch fagging 1 adopts the steel sheet preparation, and steel sheet thickness slightly is less than convection tube clearance, increases support intensity through increasing its width.
The pressure testing tool adopts a header side supporting plate 1 to penetrate through a convection pipe sleeve on the header convection pipe side, a connecting bolt 8 is used for connecting a connecting plate 2 with the header side supporting plate 1, a compression stud 6 penetrates through a screw hole formed in a joint of a gland 4 and the header, a cowhells sealing gasket 9 between the gland and the joint is tightly compressed by utilizing the stud fastening, the tool adopts the bolt fastening, the operation is convenient, the structure is stable, the applicability is wide, the sealing performance is high, the production efficiency is effectively improved, the possibility that slag is cut in the pressure testing sealing head process and falls into the header in the conventional pressure testing method is avoided, and the service performance of a pipe screen and a water cooling wall is ensured.
