Abstract
The invention relates to a module small-channel hydraulic pressure expansion plug device comprising an clasping bolt, an clasping nut, a screwing bolt, a screwing nut, a gasket, a supporting flat plate, a seal ring, a stop block and a stop nut, wherein the bent section of the clasping bolt is sleeved on a small collection box, the threaded straight section of the clasping bolt goes upwards and passes through the supporting flat plate and is screwed by the clasping nut, the screwing bolt is inserted into an installing hole of the supporting flat plate, the bottom end of the screwing bolt is provided with the stop nut, the stop block is sleeved on the screwing bolt which is arranged at the upper end of the stop nut, the seal ring is sleeved on the screwing bolt which is arranged at the upper end of the stop block, the gasket is sleeved on the screwing bolt which is arranged at the upper end of the supporting flat plate, and the screwing nut is connected to the screwing bolt which is arranged above the gasket in a screwing mode. In the module small- channel hydraulic pressure expansion plug device, a pipe joint press cover presses a pipe joint of the small collection box, and the seal ring structure of the pipe joint is retained, so that a hydraulic pressure test can be carried quickly and successfully, thereby saving the processing difficult points of the small collection box pipe joint after hydraulic pressure and shortening manufacturing time.
Description
Technical field
The present invention relates to a kind of hydraulic testing instrument, 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 objective of the invention 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.
According to technical scheme provided by the invention, 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 present invention 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 invention.
Fig. 2 is a left view of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, the present invention 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.
