Abstract
The anti-leakage blocking device in the pipeline is used for preventing oil and gas in the pipeline from leaking when the anti-leakage blocking device is applied to construction operations such as oil field oil transportation, gas pipeline rush repair, welding and the like. Mainly by stopping up gasbag, hose, timing relief valve, check valve and gas injection joint and constitute its characterized in that: the air inlet of the blocking air bag is connected with a hose, the other end of the hose is connected with a metal pipe, and the other end of the metal pipe is connected with a timing pressure release valve; the other end of the timing pressure release valve is connected with a check valve through a metal pipe; the other end of the check valve is connected with a gas injection joint through a metal pipe. The effect is as follows: can block oil and gas pipelines and prevent oil or gas in the pipelines from leaking.
Description
Technical field
The utility model relates to oil field oil transportation, gas transmission technical field, particularly prevents that oil in the pipeline, gas from continuing to leak interim blocking device in a kind of pipeline that causes security incident during construction operation such as oil, the repairing of tracheae line, welding.
Background technique
Oil transportation in the field produces, gas transmission line use for a long time, need to carry out construction operations such as retubing, jointing or repairing pipeline sometimes.In work progress, must close the leading portion pipeline valve, and oil, the gas discharging that will need repairing in the line sections are clean, are referred to as " emptying ".Prevent that oil, gas etc. are volatile, inflammable, explosive in the construction point pipeline in the work progress, poisonous medium is lasting excessive, prevents that especially security incidents such as gas explosion, poisoning take place in the pipeline.Yet, there is the closed front end valve during site operation, because of factor affecting such as the front end closing gate are tight, the emptying pipeline section is long, cause the preceding petroleum pipeline of construction generally to adopt long-time emptying; Adopt pipeline interior " stifled butter " to adopt early-stage preparations such as natural gas line nitrogen injection displacement.The continuous complexity of preparation of construction worker, early-stage preparations time are grown, safety coefficient is lower, cost is high, befouling environment, can't guarantee the safety in the work progress fully.
The model utility content
The purpose of this utility model is: anti-leak blocking device in a kind of pipeline is provided, can stop up oil, tracheae line, stop interior oil of pipeline or gas to pass through, improve the safety reliability in oil, the tracheae line work progress, reduce the pipeline maintainance construction cost, stop simultaneously to cause pollution ecotope because of pipeline emptying.
The technical solution adopted in the utility model is: anti-leak blocking device in the pipeline, mainly form by stopping up air bag, flexible pipe, timing Decompression valves, one-way valve and gas injection joint, it is characterized in that: be connected with flexible pipe at the suction port that stops up air bag, the other end at flexible pipe is connected with metal tube, is connected with regularly Decompression valves at the other end of metal tube; The other end at the timing Decompression valves is connected with one-way valve by metal tube; The other end at one-way valve is connected with gas injection joint by metal tube.Gas injection tool is connected on the gas injection joint, can be in stopping up air bag injecting gas.After stopping up airbag inflation, can stop up oil-gas pipeline, stop up air bag and stop oil, the gas that the oil-gas pipeline front end leaks to pass through, guarantee the maintenance construction process safe.
In order to protect regularly Decompression valves, one-way valve and gas injection joint metallic member and oil-gas pipeline inwall to bump; be fixed with a cylindrical shape and protect soft overcoat on described metal tube, regularly Decompression valves, one-way valve, gas injection joint and metal tube are in the soft overcoat of protection.
Described obstruction air bag adopts rubber to make.
The soft overcoat of described protection is to adopt rubber or plastic materials to make.
The using process of anti-leak blocking device in the summary pipeline.Consult Fig. 1.At oil, tracheae line construction pipeline backfireproof, anti-leak requirement, adopt anti-leak blocking device obstruction oil-gas pipeline 7 in the pipeline.After oil-gas pipeline 7 is opened, anti-leak blocking device in the pipeline is sent in the oil-gas pipeline 7.Gas injection tool is connected on the gas injection joint 5 injecting gas in stopping up air bag 1.According to different pressures grade pipeline, the pressure gauge of observation on the gas injection tool, satisfy oil-gas pipeline 7 retaining pressure requirements after, according to the construction amount size measuring and calculating engineering time, set the regularly 3 automatic deflation times of Decompression valves.The anti-leak blocking device stops up oil-gas pipeline 7 interior medias is effectively stopped up in the pipeline.After the construction operation surface construction finished, the time that timing Decompression valves 3 sets arrived, and regularly Decompression valves 3 automatic deflations stop up air bag 1 and dwindle, and oil, gas can pass through in the oil-gas pipeline 7.The interior anti-leak blocking device of pipeline this moment is still stayed in the oil-gas pipeline 7.Stop up air bag 1 taking-up three kinds of schemes are arranged: obstruction air bags 1 were followed medium and are entered tract after 1. oil-gas pipeline 7 was gone into operation, and (regularly Decompression valves adopts soft protection overcoat to protect in this process, prevents to damage or the stifled pipeline that blocks) tackles the back taking-up by filter.2. take out by pipeline accessories and stop up air bag 1.3. on pipeline, directly make in the work progress and take out this device fast.This device possess convenient in carrying and floor space little etc., use characteristics such as efficient and convenient, safe and reliable, be applicable to all kinds of oil-gas pipeline operations, particularly large and medium-sized long distance line construction.Belong to and improve oil, tracheae line fire operation safety reliability, and the pipeline of tackling sudden pipeline leakage stops up the safety prevention measure of usefulness temporarily, have easy to use, characteristics such as investment is little, safety and environmental protection.
The beneficial effects of the utility model: anti-leak blocking device in the utility model pipeline, can stop up oil, tracheae line, stop in the pipeline oil or gas to be revealed, effectively improve oil, tracheae line efficiency of construction and safety reliability,, play anti-toxic action there being the toxic and harmful occasion.Can reduce simultaneously operation pollution on the environment and operating expenses such as the preceding emptying of construction, displacement.Reduce labor intensity, strengthen the Security of oil, the maintenance of tracheae line.
Description of drawings
Fig. 1 is an anti-leak blocking device structural profile schematic representation in the utility model pipeline.
Among the figure, 1-stops up air bag, the 2-flexible pipe, and 3-is Decompression valves regularly, the 4-one-way valve, 5-gas injection joint, 6-are protected soft overcoat, the 7-oil-gas pipeline.
