Abstract
The utility model provides a ware is prevented letting out by pipeline, its characterized in that, it includes flowmeter, solenoid valve, be equipped with flow switch in the flowmeter, flow switch is connected with the solenoid valve electricity. Its effect lies in: 1, can prevent the big waste that the leakage accident led to the fact, 2, can prevent the emergence of serious accident, 3, this device energy -saving power moves under the pipeline unfaulty conditions, and power consumption is zero, 4, this device can extensively be arranged in the pipeline of materials such as running water, crude oil, coal gas, the natural gas, various chemistry.
Description
Technical field: the utility model relates to a kind of pipe safety and prevents device, namely occurs to stop its a large amount of pipeline trap of leaking further when leaking in time at pipeline.
Background technique: in the conveying of existing various pipeline, its medium has tap water, crude oil, coal gas, rock gas, various chemical substances etc.When pipeline in conveying because breaking, the accidents such as damage and cause medium to external leakage time, existing processing method is by manually going to close from the valve of accident point pipeline minimum distance mostly.The deficiency that this kind of method in use exists is: 1, can cause larger waste, because after accident occurs, first someone to report accident treatment center, then arranged again by accident treatment center and go process from accident staff the most nearby, this can make, from the accident to there being one period of larger time period between throttle down, the medium that this time period runs off then can cause larger waste; 2, have major safety risks, because in the various media of conveying, having is much hazmat, and e.g., the media such as various poisonous chemical substance and rock gas, they are once leak and reach certain amount, then can cause the immeasurable person, property loss.
Summary of the invention: the purpose of this utility model is, for in existing Cemented filling because of to the above-mentioned deficiency existing for the method handled by pipe leakage, and a kind of pipeline trap is proposed, it can when leaking appears in pipeline, at once by closedown of pipeline, thus the generation of the waste effectively preventing medium a large amount of and serious accident.
The utility model object can be realized by following technical proposals, a kind of pipeline trap, it is characterized in that, it comprises flowmeter, solenoid valve; Be provided with flow switch in flowmeter, flow switch is electrically connected with solenoid valve.
For easy to connect in using, it also comprises a casing and the one section of two ends pipeline with adpting flange, and pipeline is located in casing, and two ends exposure is outside casing, and flowmeter and solenoid valve are located in pipeline.
For the flow switch in protection flowmeter, be provided with relay in circuit.
For opening pipeline after accident treatment, being provided with in circuit and opening switch.
For convenience of closing duct during maintenance, be provided with closing switch in circuit.
For prompting accident occurs, outside casing, be provided with alarm indicator lamp.
Effect of the present utility model is: 1, Leakage prevention accident can cause large waste, this is to be provided with flowmeter and solenoid valve in this device, they establish in the duct, flow meter settings CLV ceiling limit value, when pipeline leaks because of accident, when flow in its pipe is beyond CLV ceiling limit value, namely flowmeter can cut out solenoid valve by the flow switch in it, thus the loss that effective Leakage prevention brings; 2, the generation of serious accident can be prevented, because this device can when leaking generation, meeting closing duct at once, thus can avoid because of the very big danger that a large amount of leakage liquid is especially explosive, inflammable, toxic liquid brings; 3, this device energy saving, runs under pipeline unfaulty conditions, and power consumption is zero; 4, this device can be widely used in the conveyance conduit of the materials such as tap water, crude oil, coal gas, rock gas, various chemistry.
Accompanying drawing illustrates:
Accompanying drawing 1 is perspective view of the present utility model (broken section);
Accompanying drawing 2 is simple circuit structure schematic diagram of the present utility model.
Below in conjunction with drawings and Examples, the utility model is set forth further:
Embodiment:
See accompanying drawing 1,2, a kind of pipeline trap, it comprises flowmeter 1, solenoid valve 2, flow switch 3, relay 4, relay switch 41, relay switch 42, opens switch 5, closing switch 6, alarm indicator lamp 7, casing 8, pipeline 9 (hereinafter referred to as pipeline 9) with adpting flange.Pipeline 9 is located in casing 8, and two ends exposure is outside casing 8, and flowmeter 1 and solenoid valve 2 are located in pipeline 9.Open switch 5, closing switch 6, alarm indicator lamp 7 be located at casing 8 outer surface.Relay 4 one end is electrically connected with one end of flow switch 3, closing switch 6, relay switch 41 respectively, and the other end is electrically connected with one end of alarm indicator lamp 7 and solenoid valve 2 respectively; The other end of flow switch 3, closing switch 6, relay switch 41 is all electrically connected with the one end of opening switch 5; The other end opening switch 5 is electrically connected with one end of relay switch 42, and the other end of relay switch 42 is electrically connected with the other end of alarm indicator lamp 7 and solenoid valve 2 respectively.
The operation procedure of this device is: when occurring in pipeline that leaking its flow value is greater than set definite value in flowmeter 1, flow switch 3 cuts out, relay 4 action, relay switch 41, relay switch 42 are closed, solenoid valve 2 circuit turn-on, solenoid valve 2 cuts out, and alarm indicator lamp 7 is bright.When after Failure elimination, press and open switch 5, solenoid valve 2 is opened, and pipeline is open-minded.When keeping in repair pipeline and need closing duct or carry out feasibility test to this device, press closing switch 6, solenoid valve 2 cuts out.
