Description
Technical field
The present invention relates to the warning device of combustion gas voltage regulating station supervisory system, particularly a kind of combustion gas intelligence superpressure security alarm tensimeter.
Background technology
Since China reform and opening-up, national economy is increased fast, has become the main flow of the present industrial development of China with " scientific and technical innovation, autonomous innovation ", and China's industry is progressively to intensive style, energy-saving and emission-reduction, and the direction of low-carbon (LC) develops.Along with the reform and opening-up and the continuous development of economic construction, living standards of the people improve day by day, and the fast development of novel residential quarters adds that " each city and each small towns are come in the enforcement of West-east Gas engineering project, rock gas gradually.In order to ensure gas ductwork safety, economy, operation reliably, the equipment aggregate erection that people will have functions such as pressure adjusting, flow measurement and protection usually is same indoor, i.e. combustion gas voltage regulating station.In combustion gas conveying and assigning process, the combustion gas pressure regulation important step that is absolutely necessary.At present, each maintainer will be responsible for 20～30 line walking task, to on-the-spot voltage adjusting device is carried out daily servicing and inspection, has reduced the fault generation to a certain extent, also prolongs service life of equipment simultaneously.But because the phenomenon that ageing equipment and accidental damage meeting cause top hole pressure to rise, just possible initiation potential accident or equipment are out of service as can not in time reporting to the police, and consequence is hardly imaginable.In addition, when gas ductwork breaks down, need the maintainer just can pinpoint the problems, delayed servicing time, also influenced the user in gas ductwork downstream, also polluted atmospheric environment through after the investigation of multiple working procedure.Safety for gas facility in guaranteeing to stand and downstream bearing device; Need a kind of intelligentized gas alarm tensimeter of research; Pressure condition to station internal pressure-regulating equipment is gathered, writes down, handles, is analyzed; When breaking down alerting signal is sent on maintainer's mobile phone, makes the maintainer in time rush for the site disposal failure problems.In order to solve this difficult problem, R&D institution and science and technology in enterprise personnel utilize modern science and technology in constantly research, exploration, though obtained some progress technically, in practice, still exist the technical barrier that does not overcome as yet.
Summary of the invention
The objective of the invention is to overcome above deficiency; A kind of combustion gas intelligence superpressure security alarm tensimeter is provided, adopts advanced GPRS network system that each tensimeter duty of combustion gas voltage regulating station is carried out real time remote and follow the tracks of, when voltage adjusting device inlet and outlet pressure superpressure; Can report to the police automatically; Data message is sent on maintainer's the mobile phone, makes the maintainer in time rush for the scene and check maintenance, guarantee the gas ductwork safe and reliable operation.
The technical solution adopted for the present invention to solve the technical problems is: comprise watchcase, scale, face glass, occlusion pressure force, near switch, diffuse spot pressure, pointer, tensimeter be threaded parts, lead, compacting part, sensor coil, pressure guide hole, magnetic field, amplifier, relay M, explosion-proof isolated gate, TS relay, pulse ends, redial key; Watchcase is a cylindrical shape; The top of watchcase is provided with face glass; The lower central of face glass is provided with pointer; Be provided with scale below the pointer, one section red pressure scale zone is arranged on the scale, the sidepiece of table body is provided with near switch; Be provided with the occlusion pressure force and diffuse spot pressure near switch; The lower end of table body is provided with the tensimeter parts that are threaded, and the be threaded lower central of parts of tensimeter is provided with pressure guide hole, and the be threaded inner periphery of parts of tensimeter is provided with compacting part; Inside near switch also is provided with sensor coil, amplifier, relay M, explosion-proof isolated gate, TS relay, pulse ends, redial key; Sensor coil be connected near switch, amplifier, relay M, explosion-proof isolated gate, TS relay, pulse ends are connected through lead with redial key, have formed a kind of combustion gas intelligence superpressure security alarm tensimeter.
The know-why that the present invention adopts is: adopt advanced GPRS network system, will be transferred near the actuating signal that switch sends on maintainer's the mobile phone, realize the warning of combustion gas voltage adjusting device.During the gas pressure regulator, governor operate as normal, equipment medium pressure, the sensor coil elastic deformation in pressure guide hole is passed to this alarm pressure gauge conducts to pointer with pressure deformation.This alarm pressure list index is positioned at the ratings scope of setting, i.e. the top hole pressure normal range of voltage adjusting device, safe pressure scale value zone.When pressure regulator broke down, the top hole pressure overflow was made mouth pressure, the sensor coil elastic deformation in pressure guide hole is passed to this alarm pressure gauge; Pointer forwards near the switch place (being the alert spot pressure of the gas of setting here: be higher than the occlusion pressure force, be lower than and diffuse spot pressure), promptly red pressure scale regional extent; Through elastic deformation, send pressure signal near the sensor coil in the switch, be passed to radio-frequency amplifier through signal wire; After radio-frequency amplifier is handled; Make relay adhesive interlock contact, pass through explosion-proof isolated gate again, connection terminal case and TS relay; Signal is passed to the pulse ends of alarm telephone set through GPRS network; And the time-delay 2S put through redial key (the warning number of telephone set prestores), realized the timely warning of combustion gas voltage adjusting device like this, the maintainer in time rushes for the site disposal failure problems according to telephone prompts.The effect of amplifier is the device of the voltage of input signal or power amplification, and it will electric signal is distortionless to be amplified to required value near sending in the switch, reaches high-level efficiency and exports powerful effect.Near sending electric signal in the switch is because combustion gas voltage adjusting device internal pressure raises, around under the action of a magnetic field, and sensor coil generation elastic deformation and the voltage force signal that produces.Explosion-proof isolated gate effect is with isolating near power supply that sends in the switch and signal, prevent mixed the touching between power supply high pressure and the signal, carry out the explosion-proof processing of safe spark, having improved reliability of system operation.Relay M and TS relay play a part automatic adjusting, safeguard protection, change-over circuit near on-off circuit.
Beneficial effect of the present invention is: adopt advanced GPRS network system, will be transferred near the actuating signal that switch sends on maintainer's the mobile phone, realize the warning of combustion gas voltage adjusting device.A kind of combustion gas intelligence superpressure security alarm tensimeter has guaranteed the operation that gas ductwork is safe and reliable; The management level of air supply system have been improved; The generation of prevention gas explosion accident has alleviated maintainer's workload, has reduced the pollution to atmospheric environment; Preserve the ecological environment, also reduce the loss of country and people's property simultaneously.
