Description
Technical field
The utility model relates to steel-plastic composite pipe pressure test technology field, is specifically taper sealing steel-plastic composite pipe pressure testing device.
Background technique
At the construction field (site), after steel plastic compount pipeline installs, generally need to carry out an acceptance inspection pressure testing to its pipeline, whether meet the requirements to check steel plastic compount pipeline.At present, to the pressure testing of the steel plastic compount pipeline of taper sealing, normal needs are steel plastic compount flange short tube on steel plastic compount line end is first welded, then utilize the flange head of steel plastic compount flange short tube to connect upper flange blind plate, by blank flange, the plug at end part of steel plastic compount pipeline is lived to realize follow-up pressure testing.
Adopt the pressure testing device of above structure, after pressure testing terminates, the flange head stretching out steel plastic compount line end is also needed to amputate, and also need the steel plastic compount flange short tube to amputating manually to seal, and the pipeline that the transition electric fusion joint that need configure a kind of special construction could seal with existing taper is connected, and operates and bothers very much, not only increase pressure testing cost, and at the scene artificial sealing operation is carried out to tubing fracture because of needs, the operation being easily pipeline leaves potential safety hazard.
Model utility content
The technical problems to be solved in the utility model is, provide a kind of simple, convenient, cost is low, and the taper of pressure testing rear line security of operation sealing steel-plastic composite pipe pressure testing device.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: comprise and to be loaded in line end and the taper lock pin sequentially arranged from inside to outside, the inner conical face stuffing box gland that equipped mutually and outer circle wall and pipeline inwall are close to taper lock pin external conical shape face, and stuffing box gland end is affixed and baffle plate, hoop body that outer circle wall and pipeline inwall are close to are set in the cuff that on pipeline and one end end plate is close to pipeline tapered outer ends and baffle plate end, the other end of described cuff is provided with the inner limiting board be close to pipeline taper.
Described cuff is made up of two to four pieces of circular arc blocks, is connected between described circular arc block by bolt.
Taper sealing steel-plastic composite pipe pressure testing device of the present utility model can realize pressure testing and the pressurize of taper sealing pipeline, and because being provided with taper lock pin and stuffing box gland, in pressure testing and pressure maintaining period, be subject to the impact of pipeline internal pressure, taper lock pin can be more and more tighter be sleeved in stuffing box gland that crush seal cover makes the sealing effect of stuffing box gland more and more significant, add the setting of cuff, make taper of the present utility model seal steel-plastic composite pipe pressure testing device and can realize zero leakage in pressure testing and pressure maintaining period.Taper of the present utility model sealing steel-plastic composite pipe pressure testing device, without the need to welding, after pressure testing terminates, can take out from line end, can not cause waste, reduce pressure testing cost, the safe operation after effective guarantee pipeline pressure testing.
Further, described cuff is made up of two to four pieces of circular arc blocks, is connected between described circular arc block by bolt, is convenient to suit and the dismounting of cuff.
Accompanying drawing explanation
Fig. 1 is the side-looking structural representation of the utility model taper sealing steel-plastic composite pipe pressure testing device.
Fig. 2 is the main TV structure schematic diagram of the utility model taper sealing steel-plastic composite pipe pressure testing device.
Fig. 3 is the sectional structure schematic diagram of the utility model taper sealing steel-plastic composite pipe pressure testing device.
Shown in the utility model figure: 1 pipeline, 1.1 tapered outer ends, 1.2 tapers are inner, 2 taper lock pins, 3 stuffing box glands, 4 baffle plates, 5 cuffs, 5.1 hoop bodies, 5.2 end plates, 5.3 limiting boards.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, taper of the present utility model sealing steel-plastic composite pipe pressure testing device, comprise be loaded on pipeline 1 the end in and the taper lock pin 2 sequentially arranged from inside to outside, inner conical face be equipped with mutually with taper lock pin 2 external conical shape face and outer circle wall and pipeline 1 inwall be close to stuffing box gland 3, and stuffing box gland 3 end face is affixed and baffle plate 4, hoop body 5.1 that outer circle wall and pipeline 1 inwall are close to are set on pipeline 1 and the cuff 5 of pipeline 1 tapered outer ends 1.1 and baffle plate 4 end is close to by one end end plate 5.2.The other end of described cuff 5 is provided with the limiting board 5.3 be close to pipeline 1 taper the inner 1.2.
Described cuff 5 is made up of two to four pieces of circular arc blocks, is connected between described circular arc block by bolt.
In the present embodiment, described limiting board 5.3 is annular stop plate, and the whole circle of ring-type limiting board carries out spacing, and area of contact is large, and limit effect is better.
Taper sealing steel-plastic composite pipe pressure testing device of the present utility model can realize on-site voltage-measuring and the pressurize of pipeline, and can ensure the zero leakage in pressure testing and pressure maintaining period, and in whole pressure testing process, without the need to carrying out the welding of each parts, operates very convenient.
