Abstract
The invention discloses a device for automatically closing a pipeline during burst of a pressure container or a pressure pipeline, which belongs to the technical field of pressure containers or pressure pipelines. The device comprises the pressure container or the pressure pipeline, a medium input pipeline and a medium output pipeline, wherein a medium input sensor and a medium input control electromagnetic valve are arranged on the medium input pipeline; a medium output sensor is arranged on the medium output pipeline; and the medium input sensor, the medium input control electromagnetic valve and the medium output sensor are connected with the controller respectively. The device has the characteristics of automatic closing, safety, reliability and the like.
Description
Technical field
The present invention relates to a kind of pressurized container or pressure piping, pipeline self-closing device when especially a kind of pressurized container or pressure piping explosion.
Background technique
Explosion, leakage accident take place in the pressurized container of chemical industry class enterprise or pressure piping self, the capital causes the High Temperature High Pressure, poisonous and harmful in container or the pipeline, medium such as inflammable and explosive to be gushed, though the pipeline front end generally all is equipped with cutting-off valve, can approaching maybe can't contain but the scene of the accident is almost unmanned, thereby usually cause the pernicious of accident to spread.Existing all kinds of safety valves all start according to the pressure activated decompression mechanism that exceeds standard, but it is powerless that explosion leakage accident has been taken place for it.
Summary of the invention
Characteristics such as technical assignment of the present invention is a pipeline self-closing device when providing a kind of pressurized container or pressure piping explosion at above the deficiencies in the prior art, and this device has closes automatically, safe and reliable.
The technical solution adopted for the present invention to solve the technical problems is: pipeline self-closing device when pressurized container or pressure piping explosion, comprise pressurized container or pressure piping, medium input pipeline and medium output pipeline, wherein on described medium input pipeline, be provided with medium input pickup and medium input control mortor operated valve, be provided with medium output transducer and medium input control mortor operated valve on described medium output pipeline, described medium input pickup links to each other with controller respectively with medium input control mortor operated valve and medium output transducer.
Be provided with medium output control mortor operated valve on described medium output pipeline, described medium output control mortor operated valve links to each other with controller.
Above-mentioned controller is the difference comparison controller, and its work basic parameter is pressure, temperature, flow.
Described medium input pickup is measured medium incoming pressure, temperature, flow respectively.
Described medium output transducer is measured medium delivery pressure, temperature, flow respectively.
The present invention has following outstanding beneficial effect:
1, realizes unmanned control operation automatically, greatly reduce injury once more personnel;
2, the pernicious of containment accident effectively spreads, and helps rescue and repairing, reduced the bigger loss of economy and equipment;
3, easy for installation, existing equipment is transformed a little, directly installation gets final product;
4, with low cost, do not need to carry out very big investment, reduced the economy input of enterprise.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a working principle block diagram of the present invention.
Embodiment
Below in conjunction with Figure of description the present invention is done following detailed description.
As shown in the figure, pipeline self-closing device when pressurized container or pressure piping explosion, comprise pressurized container or pressure piping 4, medium input pipeline 1 and medium output pipeline 6, wherein on described medium input pipeline 1, be provided with medium input pickup 2 and medium input control mortor operated valve 3, be provided with medium output transducer 7 on described medium output pipeline 6, described medium input pickup 2 links to each other with difference comparison controller 5 respectively with medium input control mortor operated valve 3 and medium output transducer 7.
Be provided with medium output control mortor operated valve 8 on above-mentioned medium output pipeline 6, described medium output control mortor operated valve 8 links to each other with difference comparison controller 5, and purpose is to prevent that medium from flowing backwards because of pressure reduces generation suddenly.
Pressure, temperature, flow when described medium input pickup 2 and medium output transducer 7 are measured medium input and medium output are respectively compared by the difference comparison controller, and the action of control mortor operated valve, promptly get " differential ".
When medium output pipeline 6 when being a plurality of, the medium output flow is exactly the flow summation of a plurality of pipelines.
Working principle of the present invention is the principle according to medium incoming pressure, temperature, flow and medium delivery pressure, temperature, flow equilibrium.When pressurized container or pipeline burst occurring or leaking, the medium incoming pressure can be greater than the medium delivery pressure, the medium output flow is less than the medium input flow rate, input and output disequilibrium, at this moment be arranged on the medium input pipeline and medium output pipeline upper sensor can pass to the difference comparison controller to this signal, the difference comparison controller is by after calculating relatively, start medium input control mortor operated valve and medium output control mortor operated valve, medium input control mortor operated valve and medium output control mortor operated valve are closed, and medium just can not continue to gush and flow backwards.
Claims (5)
1. pipeline self-closing device when pressurized container or pressure piping explosion, comprise pressurized container or pressure piping, medium input pipeline and medium output pipeline, it is characterized in that on described medium input pipeline, being provided with medium input pickup and medium input control mortor operated valve, be provided with the medium output transducer on described medium output pipeline, described medium input pickup links to each other with controller respectively with medium input control mortor operated valve and medium output transducer.
2. pipeline self-closing device according to claim 1 is characterized in that being provided with medium output control mortor operated valve on described medium output pipeline, described medium output control mortor operated valve links to each other with controller.
