Description
Technical field
The present invention relates to a kind of water pressure inner expansion plug device, belong 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 (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.But this water pressure inner expansion plug is subjected to the restriction of pipe section, can not make very greatly, and ips generally is not more than 65mm, so in use labour intensity is not very big, has embodied its superiority.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of in limited caliber scope and finish hydraulic testing work in the short period of time, can shorten manufacturing time greatly, simple in structure, easily manufactured water pressure inner expansion plug device.
According to technical scheme provided by the invention, described water pressure inner expansion plug device, comprise sealing gasket, the water outlet nut, pull bar, nut, packing ring, expansion set, first O-ring seal, tapered sleeve, second O-ring seal, the awl pad, control lever, apopore, limit body and ring groove, pull bar hollow, the water outlet nut is spirally connected in pull bar one end, pull bar the other end is provided with limit body, fixing operation bar on the water outlet nut, place sealing gasket between nut and the pull bar discharging water, make that the endoporus of apopore in the control lever and pull bar is intermittently connected, at the pull bar stage casing socket packing ring and the nut that is spirally connected, on the pull bar between packing ring and the limit body, be socketed with tapered sleeve and awl pad, socket expansion set on the tapered sleeve, the awl pad is gone up socket second O-ring seal.
On expansion set, circumferentially offer ring groove, be provided with first O-ring seal in the ring groove along it.
The present invention is in limited caliber scope and finish hydraulic testing work in the short period of time, can shorten manufacturing time greatly, has simple in structure, manufacturing and advantage such as easy for installation.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram 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 is made of parts such as sealing gasket 1, water outlet nut 2, pull bar 3, nut 4, packing ring 5, expansion set 6, first O-ring seal 7, tapered sleeve 8, second O-ring seal 9, awl pad 10, control lever 11, apopore 12, limit body 13 and ring grooves 14.
This water pressure inner expansion plug device, comprise sealing gasket 1, water outlet nut 2, pull bar 3, nut 4, packing ring 5, expansion set 6, first O-ring seal 7, tapered sleeve 8, second O-ring seal 9, awl pad 10, control lever 11, apopore 12, limit body 13 and ring groove 14, pull bar 3 hollows, water outlet nut 2 is spirally connected in pull bar 3 one ends, pull bar 3 the other end are provided with limit body 13, fixing operation bar 11 on water outlet nut 2, at the placement sealing gasket 1 between nut 2 and the pull bar 3 that discharges water, make that the apopore 12 in the control lever 11 is intermittently connected with the endoporus of pull bar 3, at the pull bar 3 stage casing socket packing rings 5 and the nut 4 that is spirally connected, on the pull bar 3 between packing ring 5 and the limit body 13, be socketed with tapered sleeve 8 and awl pad 10, the expansion set 6 that socket cooperates with tapered sleeve 8 on the tapered sleeve 8, socket and awl pad 10 second O-ring seals 9 that cooperate on the awl pad 10.
On expansion set 6, circumferentially offer ring groove 14, be provided with first O-ring seal 7 in the ring groove 14 along it.
Described tapered sleeve 8 is tubular body that external diameter gradually increase less than the two ends external diameter and by the middle part to two ends for the middle part external diameter.
The ring bodies that described awl pad 10 is provided with for left and right interval on the socket pull bar 3, the left side of the right side of left side ring bodies, right side ring bodies is an inclined working.
During operation, hand acts on the control lever 11, and water outlet nut 2 is rotated, thereby makes water outlet nut 2 compress sealing gasket 1 between pull bar 3 ends and the water outlet nut 2, and apopore 12 can not water outlet, at this moment; Sealing gasket 1 between water outlet nut 2 and pull bar 3 ends is loosened, and apopore 12 can be out of the water.By rotation nut 4, tapered sleeve 8 makes expansion set 6 outer expanding, and makes the ring groove 14 first interior O-ring seals 7 of expansion set 6 compress inboard wall of tube body, and awl pad 10 makes the tight inboard wall of tube body of second O-ring seal, 9 outer swelling pressures at this moment.Sealing gasket 1 is placed on and discharges water between nut 2 and the pull bar 3, the nut 2 for the treatment of will discharge water behind the filling up water is tightened, and fills in water by expanding in the other end, boosts, and needs voltage stabilizing not fall to press after 1 minute after reaching the hydraulic testing, slowly unload and be depressed into zero-bit and open the nut 2 that discharges water then and discharge water, be i.e. hydraulic testing success.
