Description
Technical field
The present invention relates to a kind of pipe end blocking device and method for blocking thereof, particularly a kind of emergent blocking device of risk source capsule road fracture port and rapid plugging method thereof of being used for is as petrochemical industry, Coal Chemical Industry production and poisonous gas-liquid warehousing and transportation facilities pipeline and be used for coal gas, heating power, water supply the speedily carry out rescue work emergent blocking device and the rapid plugging method thereof of pipeline.
Background technique
According to statistics, the hazardous substance in the annual chemicals production is about about 4,000,000,000 tons, and these materials exist huge potential risk in production and course of conveying, in case have an accident, will cause serious consequence.
In recent years, a lot of leakage accidents took place within the border in China, and on July 7th, 2000, great accident to leak the poison gas took place at a high speed Chengdu-Chongqing, owing to do not use suitable method for blocking to cause the several firefighterses of a large amount of toxic gas leakages to be poisoned.March in 2005 Beijing-Shanghai Expressway Huaian on the 29th section liquid chlorine leakage accident because the untimely heavy casualties that caused of shutoff.The ammonia leakage accident takes place too because reasons such as shutoff overlong time have caused loss in various degree to society in carcinogenic accident to leak the poison gas of Chongqing vinyl benzene on August 18 in 2009 and Chifeng, the Inner Mongol on the 5th August in 2009.
Existing blocking device and method for blocking thereof mainly contain plugging valves instrument, external sealing type leak stopping band, binding type leak stopper, wooden leak stoppage tool, interior envelope covering leak stopping band, metal leak stopping sleeve pipe, pouring-in leak stoppage tool, stick type leak stoppage tool.Blocking device that these are traditional and method ubiquity thereof problem and are: simple in structure and poorly sealed close; Shutoff is tight and structure is too complicated, and most of blocking devices are not easy to operate more difficult manufacturing, and blocking device is relatively heavier, and inconvenience is carried, and what have then is to waste time and energy the shutoff imprecision and cause heavy losses.
The on-the-spot problem that is exposed of the disposal that has an accident mainly contains the dangerous matter sources leakage accident and takes place frequently, and the back disposal takes place to leak slowly, and method of disposal falls behind, and emergency reaction is blunt, does not have advanced processing treatment tool and method thereof etc.
Summary of the invention
The present invention is based on the deficiency of existing pipe plugging device and method for blocking thereof, a kind of device for emergently plugging risk source pipe orifice and rapid plugging method thereof are provided, and in order to solve the blocking device unreasonable structure that availability risk source capsule road is revealed, shutoff is not rapid, poorly sealed close, carry inconvenient problem.
In order to address the above problem, the measure that the present invention taked is a kind of device for emergently plugging risk source pipe orifice, its structure characteristic is to be provided with in reducing rubber seal connecting sleeve one end zigzag fashion sealing pipe clamp, the other end is provided with outside thread, outside thread is the tube cover block that has internal thread accordingly therewith, the termination of tube cover block is equipped with flow-guiding valve, and be communicated with reducing rubber seal connecting sleeve, another termination is the limit, outer, and on the limit, outer, be provided with tapped hole, be provided with the connection arm-tie in zigzag fashion sealing pipe clamp termination and be connected with the tapped hole on limit, tube cover block outer.
A kind of rapid plugging method that is used for above-mentioned device for emergently plugging risk source pipe orifice of the present invention, this method is when risky source capsule mouth takes place to leak in risk source capsule road, with tube cover block with the rubber connecting sleeve screw into, with pipe collar the rubber seal connecting sleeve is locked on the pipeline after opening the flow-guiding valve pressure release, and by bolt tightening connection arm-tie and tube cover block, close flow-guiding valve at last, promptly realize the shutoff of meeting an urgent need of risk source capsule mouth.
The present invention is a risk source capsule road fracture port quick blocking flow guide device, is as Sealing with rubber seal.Pipe collar is as fastening piece, utilize the plasticity of rubber to adapt to the irregular conditions of external diameter of pipe, rubber sealing boot is fastened on the pipeline external surface, because it is fastening to be that pipe collar carries out, can adjust certain diameter range thus, simultaneously be covered with seal groove on rubber sealing boot and the pipeline junction plane, reach pressure-bearing and sealing, purpose that reducing is adjustable, this device also possesses the diversion function that poison gas (liquid) is arranged simultaneously.
Advantage of the present invention and good effect also are: (1) this invention is simple in structure, include only five major parts in the structure, so manufacturing is easy, and cost is low; (2) adopted the mode of carrying out shutoff in the pipeline outer end, simple to operate, easy to loading and unloading, when reducing labor intensity, accelerated the speed of shutoff greatly, can win sufficient rescue time, avoid causing serious consequence; (3) adopted pipe collar as fastening piece, it is simple not only to operate, and can adjust certain diameter range, and the pipe end shutoff flow guide device application of invention is enlarged; (4) because rubber has plasticity, thereby adaptability that should invention is wider, and it is better to can be used for various emergency occasion such as pipe leakage, storage tank pipe leakage and sealing; (5) this device is not only applicable to the leakage shutoff in gas risk source, can also carry out the shutoff water conservancy diversion to the risk source of liquid medium; (6) design water conservancy diversion ball valve has two important function, and the one, pressure release in advance is very easy to the shutoff operating process, and the 2nd, can realize the diversion function of poison gas (liquid).
