Background technology
Tank valves is control jar interior space gaseous tension, suppresses vapour loss, and the protection oil tank exempts from a kind of oil tank special service valve of damage.In accordance with regulations, oil depot should be regularly detects the performance of vacuum pressure valve.At present, the on-line measuring device that does not have the storage tank vacuum pressure valve both at home and abroad.There are the vacuum pressure valve pick-up unit in the producer and the special inspection body that only produce vacuum pressure valve, bulky can only be in indoor detection, and can not finish storage and the analysis of data, can't carry out regular on-line testing and self check to vacuum pressure valve, these all affect the safe operation of oil tank.
CN2188757Y disclose a kind of can fast detecting Tank's Breather Valve pressure apparatus, but do not provide concrete structure.
Summary of the invention
The objective of the invention is to invent a kind of for the supporting safety of Tank's Breather Valve on-line measuring device, automaticity height, detect accurately, stable performance, simple to operate, the little movement of the volume positive negative pressure generator of Tank's Breather Valve flexibly.
The formation of storage tank vacuum pressure valve on-line intelligence pick-up unit is made up of Tank's Breather Valve, linker, positive negative pressure generator, pressure unit, tester and accumulator as shown in Figure 1.Tank's Breather Valve is connected with positive negative pressure generator, pressure unit through linker, and positive negative pressure generator, pressure unit are connected with tester, and accumulator connects tester.
The formation of described positive negative pressure generator as shown in Figure 2, it generates district 1, explosion-proof electrical source interface 2, polynary combination pump power switch 3, malleation delivery outlet 4, negative pressure delivery outlet 5, explosive-proof sealed case 6 and polynary combination pump 7 by positive negative pressure and forms.Polynary combination pump 7 places in the explosive-proof sealed case 6, and explosive-proof sealed case 6 outer sides have positive negative pressure to generate district 1, and explosion-proof electrical source interface 2 and polynary combination pump power switch 3 are arranged at the top that positive negative pressure generates district 1, and malleation delivery outlet 4 and negative pressure delivery outlet 5 are arranged at the bottom.
The invention effect
This positive negative pressure generator be storage tank vacuum pressure valve on-line intelligence pick-up unit supporting after, make this device be fit to outdoor online detection, has the automaticity height, detect accurately, stable performance, simple to operate, the little movement of volume all parts flexibly concentrates in the portable unit, adopt new pressurization/pressure reducing mode, microprocessor control, can in seconds once finish the test of the force value of vacuum pressure valve automatically; Arbitrarily circulation, many, multiple batches of automatic test, verification test efficient height; Guarantee the precision of testing, adopt high-precision pressure sensor, high precision usb data capture card adopts touch screen human-computer interface, and is simple to operate, judges intuitively, can print and analyze the test data storage.
The convenient especially outdoor online detection vacuum pressure valve of the present invention is widely used for online detections of storage tank vacuum pressure valve such as oil field, refinery, oil depot, transfer stations.
