Abstract
A pressurized pipeline stop leaking device includes a two ends closed arc pipeline (1) which can entirely surround the leaking parts and a let valve (2), the device is characterized in that the arc tube (1) is sealing connected with the required stop leaking pipeline, the bottom of the arc tube (1) is provided with a hole connected with the let valve (2) through a connecting pipe.
Description
Technical field:
A kind of leak stoppage device when the utility model relates to the pipe leakage that has pressure.
Background technique:
General thermoelectricity plant all adopts high temperature, high pressure unit; prolongation along with service time; equipment occurs aging; tube leaks is inevitable; and tube leaks is when serious even by forced-stopping machine; handle defective if shut down; necessary first black furnace 24 hours; just can repair; after slicing off, replaces with new pipe again in the pipeline that will sew the part place during maintenance; bring adverse influence so not only can for annual generating task, and make the Winter heat supply temperature be difficult to reach temperature required, the unit start and stop are the expense of nearly hundreds of thousands unit once.
The model utility content:
In order to solve existing technical problem in the background technique; the utility model provides a kind of pipeline with pressure leak stoppage device; this leak stoppage device can not repaired the pipeline that leaks under the outage state; make leaking medium after small diameter tube flows out, carry out dilatation; not only pressure reduces; and emission flow is big, reduces fixedly connected difficulty, leak-stopping success rate height.
The technical solution of the utility model is: this pipeline with pressure leak stoppage device, the arc pipe that the tube leaks part all can be surrounded that comprises closed at both ends, escape cock, wherein said arc pipe is connected with the pipeline of required leak-stopping is airtight, in the arc bottom of arc pipe through hole is set and is connected with escape cock by connecting tube.
As further improvement of the utility model, rush down pipeline when vertically being provided with in leakage, on the lower end surface of the closed at both ends face of arc pipe, through hole is set and is connected with another escape cock by connecting tube.And the ponding baffle plate in upwards sealing connects in the lower end surface of the closed at both ends face of arc pipe, the formation cell body.
Ponding baffle plate 4 is connected with the sealing of the lower end closed face of arc pipe 1 in described, and connecting tube is connected with arc pipe 1 through hole, and arc pipe 1 is preferably welding with airtight connection of required leak-stopping pipeline.
The utlity model has following beneficial effect: owing to take such scheme, arc pipe is connected with escape cock, make leaking medium after small diameter tube flows out, carry out dilatation, not only pressure reduces, and emission flow is big, thereby reduced the difficulty of welding, need not shut down when making pressure pipeline leakage and can handle; According to annual twice, each handle need 24 hours, per hour influence 180,000 kilowatts of electric weight/time and calculate, year can reduce the power generation loss that causes because of shutdown: 180000KW/ hour * 24 hours * 0.24 yuan/KW * 2 time=207.36 ten thousand yuan.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is structural representations of arc pipe 1 among Fig. 1.
1-arc pipe among the figure, ponding baffle plate in the 2-escape cock, 3-, 4-cell body.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, this pipeline with pressure leak stoppage device, the arc pipe 1 that the tube leaks part all can be surrounded that comprises closed at both ends, escape cock 2, wherein said arc pipe 1 is connected with the pipeline of required leak-stopping is airtight, in the arc bottom of arc pipe 1 through hole is set and is connected with escape cock 2 by connecting tube.
During actual the use, select an external diameter greater than the arc pipe 1 of sewing outer diameter tube, the external diameter of preferred arc pipe 1 approximates 2.5 times that sew outer diameter tube, and the both ends of the surface of arc pipe 1 adopt and the iron plate of arc pipe 1 uniform thickness seals; When to sew pipeline be horizontal, arc pipe 1 horizontal positioned, in arc pipe 1 bottom opening, add connecting tube and draw at end connection escape cock 2, wherein arc pipe 1 is tightly connected with connecting tube, and preferred the employing welded, the arc pipe 1 that connects escape cock surround the leakage point of sewing pipeline and with sew pipeline and be tightly connected, preferred weld has pressure owing to pipeline before the welding, so need the escape cock of connecting tube end is opened before the welding; When to sew pipeline be vertical, arc pipe 1 is arranged vertically, in the perforate of the side of arc pipe 1, adding connecting tube draws at end connection escape cock 2, and on the lower end surface of the closed at both ends face of arc pipe 1, through hole is set and is connected with another escape cock 2 by connecting tube, the arc pipe 1 that connects two escape cocks 2 surrounds the leakage point and is tightly connected preferred weld with sewing pipeline with arc pipe 1 under the state of two valve opens; For easy to connect, can upwards weld an iron plate that highly is lower than the leakage point at the lower end surface iron plate half arc place of arc pipe 1 closed at both ends face, ponding baffle plate 3 promptly, make it to become a cell body 4, and below sewing the leakage point of pipeline, the water conservancy diversion clamp is set in advance, the water conservancy diversion clamp is preferably triangle, and medium is flowed in the cell body 4 along the water conservancy diversion clamp.
Preferably partly enclose method when the pipe leakage mode is leaked for point, pipeline is preferably full encirclement method when because of the surface crackle or attenuate being arranged.
