Description
Technical field
The utility model relates to gas meter, flow meter technical field, is specifically related to a kind of anti-gas-leak shell of gas meter.
Background technology
Gas meter, flow meter is in order to the accumulative flow measurement instrument flowing through coal gas volume total amount in pipeline.Have two batch meters in table, each case built with make with immersion oil skiver or synthetic rubber, the leather bag with a constant volume.Gas Flow is out-of-date, and leather bag stretches, and thus changes the volume between leather bag and batch meter, changes spool position simultaneously, and like this, the coal gas of a circulation discharge two batch meter volumes, crank-swinging once simultaneously, and driven gear rotates, and the rotation of gear drives counter.The reading of counter is the volume of discharging coal gas.
Existing gas meter, flow meter can not give the alarm when leaking air or carry out outer row automatically to the coal gas leaked, phenomenon like this if there is gas meter, flow meter gas leakage will cause great impact to the life of people and property safety, so need a kind of anti-gas-leak shell of gas meter badly to solve the problem.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of anti-gas-leak shell of gas meter, this anti-gas-leak shell of gas meter can when gas meter, flow meter leaks air automatic alarm.
For reaching above-mentioned requirements, the technical scheme that the utility model is taked is: provide a kind of anti-gas-leak shell of gas meter to comprise for the can of device gas meter, flow meter, draft tube and escape pipe, draft tube and escape pipe are arranged at can both sides respectively, and be tightly connected with described can, master controller is provided with bottom can, air extractor, alarming horn, air pressure monitor device, the sidewall of can is provided with alarm signal generator, master controller and alarm signal generator, air extractor, alarming horn and air pressure monitor device are circuit and connect, the upper surface of air extractor is provided with the air hole for extracting leakage gas, the lateral wall of air extractor is provided with the emergency exhausting pipe for discharging leakage gas, the front end face of can is provided with reading window, master controller, alarming horn and air pressure monitor device are all sealed in can.
This anti-gas-leak shell of gas meter is by arranging alarm signal generator, master controller, air extractor, alarming horn and air pressure monitor device, achieve when gas meter, flow meter leaks air, air pressure in can change, air pressure monitor device can send a signal to master controller, master controller can control air extractor and extracted out by the coal gas leaked and get rid of from emergency exhausting pipe, and given the alarm by alarming horn, carry out remote alarms by alarm signal generator simultaneously.
Accompanying drawing explanation
