The utility model relates to a hydraulic expansion plug device for a modular small header, which comprises a tightening bolt, a tightening nut, a tightening bolt, a tightening nut, a washer, a supporting plate, a sealing ring, a stop block and a limit nut, and a tightening bolt The curved section of the holding bolt is set on the small header, and the threaded straight section of the holding bolt passes through the supporting plate upwards and is tightened with a holding nut. The tightening bolt is inserted into the mounting hole of the supporting plate. The tightening bolt at the upper end of the limit nut is socketed with a stopper, the tightening bolt at the upper end of the stopper is sleeved with a sealing ring, the washer is sleeved on the tightening bolt at the upper end of the support plate, and the tightening bolt above the washer is screwed with a tightening nut. The utility model makes the gland of the pipe joint of the small header tightly pressed with the pipe joint, and retains the sealing ring structure of the pipe joint, so that the hydraulic test can be carried out quickly and well, and the processing of the small header pipe joint after the hydraulic pressure is saved The difficulty of shortening the manufacturing time.
Description
Technical field
The utility model relates to a kind of hydraulic testing instrument, and specifically a kind of module small-channel hydraulic pressure expansion plug device belongs to hydraulic testing equipment technical field.
Background technology
In the plug hydraulic testing instrument that expands be necessary tool in the pressure-containing member manufacture process such as boiler coiled pipe, it utilizes one group (being generally three) to have the expansion set of serrate tooth under the extruding of one group of tapered sleeve, tightly sting the jail with tube wall, and O-ring seal and tube wall tightly sealed, again by water inlet water inlet, through boosting, the voltage stabilizing stage is until finishing the hydraulic testing.Former little header carries out the hydraulic testing to be needed the pipe adapter pressure surplus that discharges water, and welding end cap and pipe adapter, and water test finishes also need cut metalworkings such as surplus, chamfering.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, thus provide a kind of make little header pipe joint gland and pipe adapter compresses, the ring structure that kept pipe adapter again make the hydraulic testing carry out faster and betterly, can save little header pipe joint processing behind the hydraulic pressure difficult point, shorten the module small-channel hydraulic pressure expansion plug device of manufacturing time.
The technical scheme that provides according to the utility model, described module small-channel hydraulic pressure expansion plug device, it comprises holds bolt tightly, hold nut tightly, tight a bolt, fastening nut, packing ring, support plate, O-ring seal, block and stop nut, the bending section of holding bolt tightly is enclosed within on the little collection case, the screw thread straight section of holding bolt tightly upwards passes support plate also with holding nut screwing clamping tightly, tight a bolt and insert in the mounting hole of support plate, the bottom is provided with stop nut tighting a bolt, socket block on the tighting a bolt of stop nut upper end, be socketed with O-ring seal on the tighting a bolt of block upper end, fastening nut is spirally connected on the socket packing ring on the tighting a bolt of support plate upper end, the tighting a bolt of packing ring top.
The utility model compresses little header pipe joint gland and pipe adapter, has kept the ring structure of pipe adapter again, thereby makes the hydraulic testing carry out faster and betterly, has saved the difficult point of little header pipe joint processing behind the hydraulic pressure, shortens manufacturing time.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a left view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure, the utility model mainly by hold bolt 1 tightly, hold nut 2 tightly, tight a bolt 3, fastening nut 4, packing ring 5, support plate 6, O-ring seal 7, block 8 and stop nut 9 etc. constitute.
This module small-channel hydraulic pressure expansion plug device, it comprises holds bolt 1 tightly, hold nut 2 tightly, tight a bolt 3, fastening nut 4, packing ring 5, support plate 6, O-ring seal 7, block 8 and stop nut 9, the bending section of holding bolt 1 tightly is enclosed within on the little collection case, the screw thread straight section of holding bolt 1 tightly upwards passes support plate 6 and also tightens with holding nut 2 tightly, in the mounting hole of the 3 insertion support plate 6 that tight a bolt, 3 bottoms are provided with stop nut 9 tighting a bolt, the socket block 8 on 3 that tights a bolt in stop nut 9 upper ends, tighting a bolt of block 8 upper ends is socketed with three O-ring seals 7 on 3, the socket packing ring 5 on 3 that tights a bolt in support plate 6 upper ends, the fastening nut 4 that is spirally connected on 3 that tights a bolt of packing ring 5 tops.
During work, bolt 1 curved end of holding tightly of U type is enclosed within on the little collection case, and the other end passes support plate 6 and tightens with the nut 2 of holding tightly of M12, and simultaneously block 8 and high-pressure seal ring 7 is tightened in the pipe adapter, when screwing fastening nut 4, guaranteeing four, to hold nut 2 tightly evenly stressed.Screw fastening nut 4, with high-pressure seal ring 7 and pipe adapter swelling.Body connects into water then, slowly boosts to hydraulic test pressure behind the filling up water, and voltage stabilizing do not fall not to be pressed after 1 minute, i.e. hydraulic testing success is slowly unloaded and is depressed into zero-bit and discharges water then, thereby finishes the overall process of the hydraulic testing.
