The pressure testing device for the steel sleeve pipeline connector can be used for solving the problem of tightness bulge test on a conventional pipeline installation connector, can be assembled on site, is used for pressure testing during construction and can be used for timely finding problems.
Description
Technical field
The utility model relates to a kind of for carrying the pressure testing device of the pipe joint tightnesses such as liquid, gas, especially a kind of steel sleeve pipe joint pressure testing device.
Background technology
In the pipeline construction process, the interface between pipeline and pipeline is inevitable.After mostly adopting segmentation or whole piece circuit to install, at present China's pipe joint leak test carries out the hydraulic testing.Tradition bulge test water consumption is large, waste water resource.The tradition bulge test is to check afterwards, not only causes pipeline installation repair rate high, and reprocesses difficulty, has both extended construction period, has greatly increased again executive cost.
The utility model content
The purpose of this utility model is to provide a kind of above-mentioned existing pipeline mounting interface tightness bulge test problem that solves, and can assemble at the scene, limit construction limit pressure testing, the steel sleeve pipe joint pressure testing device that can pinpoint the problems in time.
For achieving the above object, the utility model adopts following technical scheme: steel sleeve pipe joint pressure testing device, comprise the two plate-like packer accessories that relatively arrange and be arranged on the sleeve pipe between two packer accessories, the toroidal cavity of the outside of sleeve between two packer accessories is formed for holding the ring groove of highly pressurised liquid, on sleeve pipe or on packer accessory, be provided with ring groove, be communicated with, for being connected the joint of suppressing of test pump.
Described sleeve pipe is steel sleeve, and the border, axial middle part of steel sleeve is provided with impression, and it is inwardly contraction-like that the two-port of steel sleeve all is, and the card of packer accessory is provided with positioning convex, and the two-port of steel sleeve is set in respectively the outer ring of positioning convex on two packer accessories.
The two-port of steel sleeve is two taper ports.
Described packer accessory is ring flange, and two ring flanges are bolted connection, and bolt is positioned at sleeve pipe.
Be equipped with annular O-ring seal between each sleeve port and its ring flange closed on, O-ring seal inner peripheral surface shape and steel sleeve port external surface shape are suitable, the O-ring seal inner peripheral surface is coated on the corresponding steel sleeve port outside, and the external diameter of O-ring seal is consistent with the ring flange external diameter.
The described joint of suppressing is positioned at it casing pipe, and the sleeve pipe pipe shaft is provided with bolt hole, and bolt hole is through hole, establishes bleeder screw in bolt hole.
Described positioning convex is annular protrusion.
Steel sleeve pipe joint pressure testing device described in the utility model, can limit construction limit pressure testing, pinpoints the problems in time, and making the repair rate after pipeline is installed is zero, has shortened the duration, has greatly saved fund.Two ring flanges, O-ring seal, steel sleeve form one at the fastening lower and pipe joint of bolt, and water shutoff is good, and bearing capacity is large.Bulge test institute water requirement is few, has saved water resource, and easy and simple to handle, time saving and energy saving.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Steel sleeve pipe joint pressure testing device as shown in Figure 1, comprise the plate-like packer accessory that two cards are oppositely arranged and be arranged on the sleeve pipe between two packer accessories, two packer accessories and sleeve pipe are the coaxial line setting, and described packer accessory is ring flange 1, and the size dimension of two ring flanges 1 is identical.Sleeve pipe is steel sleeve 4, and the border, axial middle part of steel sleeve 4 is provided with impression, and it is inwardly contraction-like that the two-port of steel sleeve 4 all is, and the two-port of steel sleeve 4 is two taper ports.
The card towards steel sleeve 4 of each ring flange 1 is equipped with positioning convex 10, described positioning convex 10 is annular protrusion, the two-port of steel sleeve 4 is set in respectively the outer ring of positioning convex 10 on two ring flanges 1, so that steel sleeve 4 can not rock, and two ring flanges 1 are fastenedly connected by bolt 2, and bolt 2 is positioned at steel sleeve 4.
Like this, between two packer accessories---the toroidal cavity of the outside of sleeve between two ring flanges 1 is formed for holding the ring groove 9 of highly pressurised liquid, hole on ring flange 1 is the corresponding steel sleeve 4 port inboards that are positioned at all, be equipped with annular O-ring seal 3 between each steel sleeve 4 port and its ring flange closed on 1, O-ring seal 3 inner peripheral surface shapes and steel sleeve 4 port external surface shape are suitable, O-ring seal 3 inner peripheral surface are coated on the corresponding steel sleeve 4 port outsides, and the external diameter of O-ring seal 3 is consistent with ring flange 1 external diameter.
On steel sleeve 4, be provided with ring groove 9, be communicated with, suppress joint 6 for what be connected test pump, the described joint 6 of suppressing is positioned on steel sleeve 4 pipe shafts, and steel sleeve 4 pipe shafts also are provided with bolt hole, bolt hole is through hole, establishes bleeder screw 5 in bolt hole.
Certainly, the utility model is not limited to above-mentioned form, bleeder screw 5 and suppress joint 6 and all can be arranged on packer accessory---and on ring flange 1, still, both all are arranged on steel sleeve 4 is best mode.Suppress joint 6 for prior art, therefore do not describe in detail.
