The utility model has simple and scientific structural design, low manufacturing cost and good safety performance, is directly installed on the pipeline and is convenient in both of installation and maintenance.
Description
Technical field:
The utility model relates to safety-valve accessory technical field, refers in particular to fluid and reveals analyzer.
Background technology:
Fluid refers to gas or liquid, generally include rock gas, petroleum gas and other chemical industry usefulness gas etc., liquid generally includes tap water, pure water, oil etc., after above-mentioned rock gas, petroleum gas, oil etc. leak, often consequence is serious, causes that property is suffered a loss, threat to life safety and produce environmental pollution.
At present, the supporting protection of this type of safety, the leak detection facility that occur on the market all are to adopt detection of electrons, and its complex structure costs an arm and a leg, and installation and maintenance simultaneously is all inconvenient.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art, and provides fluid to reveal analyzer, and the simple science of its structural design is directly installed on the pipeline, and installation and maintenance all make things convenient for, and cost is low, and security performance is good.
For achieving the above object, the utility model adopts following technical scheme, it comprises controller, solenoid valve, total flow sensor, valve, controller is connected with solenoid valve, total flow sensor, valve on the pipeline, solenoid valve is installed in total flow sensor entrance point, and valve is installed on the lateral.
Described lateral, valve are at least more than one.
To be controller be connected with solenoid valve, total flow sensor, valve on the pipeline the utility model beneficial effect, and solenoid valve is installed in total flow sensor entrance point, and valve is installed on the lateral, each parts is directly installed on the pipeline, installation and maintenance all make things convenient for, and cost is low, and security performance is good.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a principle of work synoptic diagram of the present utility model.
Embodiment:
See shown in Fig. 1,2: the utility model comprises, it comprises controller 1, solenoid valve 2, total flow sensor 3, valve 4, controller 1 is connected with solenoid valve 2, total flow sensor 3, valve 4 on the pipeline, solenoid valve 2 is installed in total flow sensor 3 entrance points, and valve 4 is installed on the lateral.
Described lateral, valve 4 are at least more than one.
The utility model is installed on the fluid line, and its principle of work is:
The user is valve-off 4 after using fluid to finish, valve 4 sent a signal of closing and gave controller 1 (as the multiple-limb pipeline and simultaneously in use this moment, has only just controlled device 1 confirmation of receipt of last signal of closing), controller 1 is received valve 4 shutdown signals, close solenoid valve 2 after postponing some seconds, guarantee that solenoid valve 2 to the hydrodynamic pressure between the valve 4 keeps consistent with solenoid valve 2 fluid supply pressure before.This stage is referred to as " pressurization ", and corresponding valve 4 closes to the 2 late release time periods of solenoid valve.
Leak as solenoid valve 2 to the fluid in the pipeline between the valve 4 (containing valve), must cause solenoid valve 2 to the hydrodynamic pressure between the valve 4 to descend; Otherwise pipeline pressure remains unchanged.This stage is referred to as " voltage stabilizing ", and corresponding solenoid valve 2 late releases are 2 opening time of solenoid valve section extremely next time.
Controller 1 picks up counting after solenoid valve 2 late releases, when timing during to the time value set solenoid valve 2 open.When pipeline exists fluid to reveal, the pressure of pipeline must reduce, because the pressure of solenoid valve 2 front ends remains unchanged, in the 2 front end supply flow direction of flow solenoid valves of solenoid valve in a flash, 2 rear ends (being that solenoid valve 2 is to pipeline between the valve 4) that solenoid valve 2 is opened, mobile driving flow sensor 1 action of fluid is to controller feed flow information; Solenoid valve 2 pressure at two ends unanimities when not having fluid to reveal, no fluid flows.This stage is referred to as " pressure measurement ", and corresponding solenoid valve 2 is opened into solenoid valve 2 shut-in time section once more.
After controller 1 receives the information of flow sensor 3, carry out statistical study, then with the normal stream value contrast of setting, when greater than the standard value set, controller 1 sends alerting signal, closes solenoid valve 2 simultaneously; When being less than or equal to the standard value of setting, controller thinks that pipeline is normal, does not have and reveals.This stage is referred to as " calculating ".
In the real fluid supply environment, exist the situation of solenoid valve 2 front end supply pressure shakinesses, even supply pressure is less than the pressure of pressurization rear electromagnetic valve 2 to pipeline between the valve 4, do not have at pipeline and to reveal or situation that amount of leakage may cause fluid to flow backwards when very little, be the potential risk that remedies so produce, but the time in proper extension " voltage stabilizing " stage.
Flow information calculates with contrast module, timing module, control circuit and warning circuit and is integrated in this circuit in the controller 1, but also can independently separate.Flow information calculates the controller of forming with contrast module, timing module, control circuit, can adopt forms such as discrete component, integrated circuit, single-chip microcomputer to implement its function.
Controller circuitry or program are increased in fluid and reveal in the control of protector; change by information delivery rate sensor the information input function of valve alternative; maybe can consider provides valve closing signal by the combustion gas flame-out protection device, then can omit production cost significantly.
The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
