Abstract
The utility model discloses a pipe end pressure testing apparatus, which contains blocks and block pipes, wherein at least two blocks are uniformly distributed on the external surface of the pipe end, the block pipe is in barrel shape, a clamp type structure is provided on the lower end of the barrel wall, the clamp type structure can be attached with the block, a bolt and a nut are provided on the barrel bottom, the bolt bottom is connected to the baffle, the baffle is located in the inner cavity of the tube, a limit ring and a sealing cushion are provided in sequence between the interior surface of the barrel bottom and the baffle. The top circle surface of the baffle is conical; the interior surface of the sealing cushion is also conical and constitutes an automatic seal structure with the baffle, or the sealing cushion is an O shape ring, and constitute an automatic seal structure with the baffle. The utility model has simple and reasonable structure, easy operatio, improved steel tube pressure testing efficacy, reduced material consumption and time consumption.
Description
One. technical field: the utility model relates to a kind of pressure testing device, specifically relates to a kind of pipe end pressure testing device.
Two. background technology: when pipe carried out pressure test, common way was that closure plate seals pipe end at the pipe end closure plate of burn-oning, and injection pressure in pipe also will slice off closure plate after the pressure testing then, and the waste material of taking a lot of work increases experimentation cost.
Three. the utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, the pipe end pressure testing device of a kind of structure advantages of simple, easy to use and high efficiency is provided.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of pipe end pressure testing device, contain block and retaining pipe, it is characterized in that: described block has two at least, the uniform outside surface that is fixed on tube end, and described retaining pipe is for disclosing type, the lower end of its barrel wall is provided with the clamping hoop type structure, this clamping hoop type structure can articulate with described block, and the described bucket end is provided with screw bolt and nut, and the bottom of this bolt is connected with baffle plate, described baffle plate is arranged in described tube cavity, is disposed with baffle ring and sealing gasket between described bucket end inside surface and the baffle plate.
Described baffle plate outer round surface is taper; Described sealing gasket inside surface also is taper, and constitutes the self-tightening sealing structure with described baffle plate, and perhaps described sealing gasket is O shape ring, and constitutes the self-tightening sealing structure with baffle plate.
Described block is two, three or four.
The beneficial effects of the utility model are:
1, the utility model is simple and reasonable, and is easy to use, improved the pressure testing effect of steel pipe, reduced the consumption of material and the consumption of time.
2, the block of the utility model pipe end does not need to remove, laborsaving saving time, and in addition, the retaining pipe can reuse, and reduces use cost.
3, be the clip combination between the utility model retaining pipe and the block, be convenient to dismounting, in addition, adopt sealing gasket to seal, along with the rising sealing gasket of pipe internal pressure is compacted, realize self-tightening sealing, and pressure is big more during pressure testing, sealing effectiveness is good more.
4, the utility model easy accessibility, high efficiency is easy to promotion and implementation, has good economic benefit after the popularization.
Four. description of drawings:
Fig. 1 is the structural representation of pipe end pressure testing device;
Fig. 2 is the vertical view cutaway drawing of pipe end pressure testing device shown in Figure 1.
Five. embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, among the figure, the pipe end pressure testing device contains block 2 and retaining pipe 3, block 2 has two (can be elected to be two, three, four or more as required) at least, the uniform outside surface that is fixed on pipe 1 end, retaining pipe 3 is for disclosing type, the lower end of its barrel wall is provided with the clamping hoop type structure, this clamping hoop type structure can articulate with block 2, the bucket end, be provided with screw bolt and nut 6, the bottom of this bolt is connected with baffle plate 7, and baffle plate 7 is arranged in pipe 1 inner chamber, is disposed with baffle ring 5 and sealing gasket 4 between bucket end inside surface and the baffle plate 7.
During test, to keep off pipe 3 is sleeved on the pipe 1, baffle plate 7, sealing gasket 4 and baffle ring 5 are arranged in the inner chamber of pipe 1, the clamping hoop type structure of retaining pipe 3 lower ends is passed through between adjacent blockers 2, rotates retaining pipe 3, and the clamping hoop type structure is just blocked block 2, fastening nut, make barrel base pressure compel baffle ring 5, thereby make baffle ring 5 compressing sealing gaskets 4, reach sealing effectiveness.During pressure testing along with the rising of pipe 1 internal pressure, sealing gasket 4 compacted (self-tightening sealing).After pressure testing finishes, unclamp nut, rotation retaining pipe 3 passes through the clamping hoop type structure of retaining pipe 3 lower ends once more between adjacent blockers 2 again, can keep off pipe 3 and take off, and finishes a working cycle.And two blocks 2 of burn-oning generally do not need to remove.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
