Technical field
This utility model relates to pipeline pressurization automatic alarm field, a kind of pipeline applied voltage test supervising device.
Background technology
At present, hydroelectric project exists water supply events in operation inside and outside many Factory Buildings, because construction needs must carry out pipeline pressure test at the scene, come into operation after meeting design pressure after test, but limited by pipeline stress deformation, FlexbleJoint stress deformation scope, booster and FlexbleJoint generation explosion phenomenon the most often occur, causes pipeline and Accessory Members to damage, and artificial packer permeability test is dangerous greatly, potential safety hazard is big.Therefore we need a kind of more simple to operate than artificial packer permeability test, and safety coefficient is high, controllability is strong, protective conduit and the pipeline applied voltage test automatic alarm control system of Accessory Members.
Summary of the invention
For solving the technical problem of above-mentioned existence, this utility model provides a kind of pipeline applied voltage test supervising device, simple in construction, safe and effective, reliable and stable, easy to use.
For reaching above-mentioned purpose, this utility model be the technical scheme is that
A kind of pipeline applied voltage test supervising device, it includes the pipeline body of pipeline and FlexbleJoint, it is separately positioned on the input oral area of pipeline, the outfan oral area of pipeline, the centre position of pipeline, the input oral area of FlexbleJoint and the outfan oral area of FlexbleJoint and for monitoring pipeline and the pressure transducer of FlexbleJoint internal pressure, it is arranged on FlexbleJoint and for monitoring the displacement transducer of the outer support tension of FlexbleJoint, it is set to be connected with pressure transducer and displacement transducer respectively and alarm device with the input signal of pressure transducer and displacement transducer as control signal.
Described pipeline body also includes pressure pump and non-return valve, and the input oral area of pipeline couples pressure pump, and non-return valve is positioned at end to the front in the middle of pipeline.
Being provided with piezoelectric semiconductor's thin slice on pressure transducer, pressure transducer is fixed by the outfan oral area pressing of piezoelectric semiconductor's thin slice with input oral area, the outfan oral area of pipeline, the centre position of pipeline, the input oral area of FlexbleJoint and the FlexbleJoint of pipeline.
Described alarm device includes signal input module, warning circuit and signal output module, and signal input module connects warning circuit, and warning circuit connects signal output module, and signal output module connects pressure pump.
Described warning circuit includes signal lights, buzzer, signal lights and buzzer series connection.
As preferably, this pipeline applied voltage test supervising device shares 5 pressure transducers.
As preferably, each display lamp and buzzer one single circuit of composition and each display lamp are provided with numbering, display lamp and pressure transducer or displacement transducer are one to one, alarm device is reported to the police and is compareed display lamp numbering simultaneously, therefore learns which position parts can not meet design requirement.
In pipeline applied voltage test, open pressure pump, to pipe water, when pipeline bear pressure reach the upper limit time, it is arranged on the input oral area of pipeline, the outfan oral area of pipeline, the centre position of pipeline, the pressure transducer piezoelectric semiconductor thin metal plate of the input oral area of FlexbleJoint and the outfan oral area of FlexbleJoint produces alarm device input signal, the displacement transducer being arranged on FlexbleJoint produces alarm device input signal simultaneously, pressure signal is converted into current signal by pressure transducer, displacement signal is converted into current signal by displacement transducer, current signal passes to alarm device, alarm activation, signal lights flashes, buzzer warning, after warning, alarm device controls pressure pump and quits work.
This utility model owing to adding pressure ratio Manual pressurizing safety and reliability by pressure pump to pipeline, simple in construction, easy to use, controllability is little with Manual pressurizing test risk compared by force, makes whole pressure system be in feature controlled, that slave mode improves work efficiency.
