Detailed Description
In order to facilitate a better understanding of the invention, the invention is further illustrated by the following examples in conjunction with the accompanying drawings.
As shown in fig. 1. The fast pipeline repairing apparatus includes sealed air bag, corresponding fixing device, etc. The sealed air bag is a circular air bag 1 which is matched with the inner peripheral wall of a corresponding pipeline 8, and the fixing device is a closed fixing and strengthening device. The closed fixing and retaining reinforcer includes a closed support part and a fixing part. The closed supporting part is composed of a pore plate body 3, and the solid part is composed of a supporting ring groove 2 which is arranged around the outer peripheral wall of the pore plate body 3 in an airtight mode and has an arc or semicircular cross section. The middle through hole of the hole plate body forms a discharge hole 5, and the annular sealing air bag is arranged between the inner peripheral wall of the corresponding pipeline and the supporting ring groove 2 in an airtight mode. The annular sealing air bag can be fixedly connected to the inner wall surface of the annular groove through gluing.
The circular sealed air bag 1 is provided with an inflating nozzle 4 which is externally led through a corresponding inflating hose. After the annular sealing air bag is inflated, the annular sealing air bag is in sealing, jacking and supporting tension type connection with the inner peripheral wall surface of the corresponding pipeline through the hole plate body and the supporting ring groove 2 thereof. The fixing device enables the sealing air bag and the inner peripheral wall of the corresponding part of the pipeline to form the enhanced positioning, fixing and sealing combination strength in a corresponding fixing shape mode through the corresponding structure and shape, and the fixing and sealing strength and the sealing performance of the sealing air bag and the pipeline can be enhanced, ensured and effectively improved.
The through hole in the hole plate body can form a quick connection with the corresponding discharge pipe 6 through connection modes such as internal threads and the like. The drain is provided with a valve 7.
When in use, the non-inflated ring-shaped sealing air bag and the fixing device thereof can be inserted into the pipeline by operating the drainage pipe and then inflated to seal the ring-shaped sealing air bag at the corresponding position of the pipeline. The pipeline can be correspondingly processed. If a control valve such as a ball valve or a gate valve 9 is additionally arranged on the pipeline. After the treatment is finished, the annular sealed air bag is exhausted, and then the solid device and the sealed air bag are taken out from the inner cavity of the ball valve or the gate valve. The inflation pressure of the circular ring-shaped sealing air bag can determine the sealing force according to the pressure of the fluid medium of the pipeline.
In another embodiment, as shown in fig. 2 and 3. The closed supporting part comprises a ring groove body 2a with a circular opening cross section, and an inflating nozzle 4 passes through the closed supporting part in an airtight mode and is led out. The annular groove body 2a with a circular opening forms a large-area supporting and fixing shape for the annular sealing air bag, so that the annular sealing air bag and a corresponding pipeline can form relatively larger attaching, positioning, fixing and sealing force. The rest of the structure and the corresponding using method of the present example can be similar to the above-mentioned embodiment.
In another embodiment, the closed type fixed retention reinforcer is fixed on the ground or a corresponding fixed object outside the pipeline through the drainage pipe leading-out section. Such as by snapping the drain tube onto an external fixture or post. So as to further assist the reliable and stable positioning of the annular sealing air bag to seal the pipeline. It is more suitable for relatively higher fluid pressure or more reliable operation of the pipeline rapid first-aid repair device, and the like. In this case, the valve to be installed may be passed through the drain pipe in advance, and then the drain pipe may be fixed. The rest of the structure and the corresponding using method of the embodiment can be similar to any of the above embodiments.
In another embodiment, the inner wall of the fixing part is provided with a sealing part, and the sealing part is composed of a plurality of annular raised rib sheets which are respectively distributed on the inner wall of the ring groove cavity or the ring groove body around the axis and are connected with the sealing air bag in an airtight mode. The annular sealing air bag and the closed supporting part are mutually fixed through two symmetrical bolts. The rest of the structure and the corresponding method of use of this example can be similar to those of the above-described embodiments 2 or 3.
