Embodiment
Below by indefiniteness embodiment and the present invention is further illustrated by reference to the accompanying drawings:
As shown in Figure 1-Figure 3, embodiments provide a kind of hydraulic test of pipeline blocking device, comprise circular closure plate 1; Seal ring 2, seal ring 2 is fixed on the excircle of closure plate 1; Supporting adjustment rack 3, supporting adjustment rack 3 is combined by the steel plate 31 of substantially horizontal and the steel plate 31 of vertical direction, and supporting adjustment rack 3 is connected on the side plate face of closure plate 1; At least two symmetrically arranged regulating mechanisms 4, regulating mechanism 4 is installed on the outer end of supporting adjustment rack 3, and regulating mechanism 4 is for adjusting the gap between seal ring 2 and pressure testing pipeline; Limiting stopper 5, limiting stopper 5 is installed on the end of regulating mechanism 4 near closure plate 1 excircle, each regulating mechanism 4 is all provided with a limiting stopper 5; Mobile assisting agency 6, mobile assisting agency 6 is installed on closure plate 1 and supporting adjustment rack 3.
The present invention is when reality uses, blocking device entirety being positioned over treats in the pipeline of pressure testing, by mobile assisting agency 6, blocking device is moved to specified position, limiting stopper 5 is welded in pipe interior, to limit the displacement of blocking device along conduit axis, the gap smaller between seal ring 2 and pressure testing pipeline is made by adjustment regulating mechanism 4, until pressure testing pipeline can be sealed completely, reach pressure testing requirement, after pressure testing, regulate regulating mechanism 4, gap between seal ring 2 and pressure testing pipeline is increased, then regulating mechanism 4 and limiting stopper 5 are departed from, just blocking device can be shifted out from pressure testing pipeline, limiting stopper can not be removed after pressure testing, only need reconfigure a limiting stopper 5, blocking device just can continue on for the pipeline pressure test of identical caliber, therefore, the blocking device that the present invention proposes is not only convenient to be installed and removes, can also reuse, effectively can save construction investment.
Concrete, regulating mechanism 4 is set to four, each regulating mechanism 4 comprises adjustment handwheel 41, the stud 42 be connected with adjustment handwheel 41, the nut A43 coordinated with stud 42, limiting stopper 5 is provided with nut B51, stud 42 and nut B51 are connected, before pipeline pressure test, adjustment handwheel 41 and limiting stopper 5 are cooperated together by stud 42 and nut A43's and nut B51, after pipeline pressure test, nut B51 on limiting stopper 5 and limiting stopper 5 stays in the duct, rotating adjustment handwheel 41 makes regulating mechanism 4 and limiting stopper 5 depart from, thus achieve the disengaging of blocking device, this screw-thread fit Placement is convenient to the installation and removal of adjust structure 4, namely the installation and removal of blocking device are facilitated.
Mobile assisting agency 6 comprises road wheel 61, upper saw pulley 62 and overturn-preventing wheel 63, road wheel 61 is for being installed on closure plate 1 footpath wheel downwards, upper saw pulley 62 is for being installed on the wheel of the radial both sides of closure plate 1, overturn-preventing wheel 63 is for being installed on the wheel of closure plate 1 radial top, after blocking device puts into pipeline, road wheel 61, upper saw pulley 62 contact with inner-walls of duct with overturn-preventing wheel 63.Because pressure testing closure plate 1 is generally steel plate, weight is larger, arrange road wheel 61, upper saw pulley 62 and overturn-preventing wheel 63 can make to be rolling friction between blocking device and inner-walls of duct, reduce the resistance of the movement of blocking device in pipeline, the direction of blocking device movement in pipeline can also be kept, stability when keeping blocking device to move in pipeline.
For increasing stability when blocking device moves further, road wheel 61 and overturn-preventing wheel 63 are set to three, three road wheel 61 distributions triangular in shape respectively, the 63 also distributions triangular in shape of three overturn-preventing wheels, upper saw pulley 62 is set to two, respectively arranges one in the radial both sides of closure plate 1.
For convenience of the movement of operation blocking device, mobile assisting agency 6 also comprises draw ring 64 and handle 65, and draw ring 64 and handle 65 are separately positioned on the both sides of closure plate 1 axis, arranges like this and also helps blocking device moving outside pressure testing pipeline.
Seal ring 2 is fixed on closure plate 1 by bolt, nut and annular pressing plate, when seal ring 2 serious wear, is turned on by bolt and nut, just the seal ring 2 of wearing and tearing can be changed, simple to operation.
Seal ring 2 can be the shaped rubber circle of one-way water stop or two-way water stop, when pressure testing section carries out continuous pressure testing, the water of upstream pressure testing section is put into downstream pressure testing section and carries out pressure testing, now, select the anisotropic rubber circle of two-way water stop, so no matter water is in upstream pressure testing section or downstream pressure testing section, and seal ring 2 can be isolated the water of upstream pressure testing section and downstream pressure testing section well.
Other parts in the present embodiment adopt known technology, do not repeat them here.
Above-described embodiment for explanation of the present invention, is not only that those skilled in the art also can make a change on this basis to its restriction.
