Description
Technical field
The utility model relates to the gas meter, flow meter technical field, especially relates to a kind of gas meter, flow meter anti-theft device of gas.
Background technology
Gas meter, flow meter has national Specification at present; Only stipulated during the gas meter, flow meter reversal connection that counter do not count, but can not effectively stop the gas behavior of stealing of gas meter, flow meter, domestic most gas meter, flow meter all still is that anti-reverse-rotation device is housed in gas meter, flow meter now; But this device only can be used to stop counter not reverse; Can not effectively end gas, gas meter, flow meter is the normal gas of crossing of gas ability jack-up gas meter, flow meter valve gap when reversal connection, and the user can normally use combustion gas to cook.
Use the gas phenomenon for fear of the gas meter, flow meter reversal connection, a lot of gas meter, flow meter manufacturers idea of also racking one's brains is improved oneself gas meter, flow meter, strives accomplishing only gas of reversal connection.New gas meter, flow meter national standard (waiting to implement issue) also clearly proposes gas meter, flow meter first and can install additional and prevent gas reverse flow device, preventing robber's gas behavior of user, and has stipulated corresponding amount of leakage.Though existing gas meter, flow meter anti-backflow device ability short-term stops the use of gas, from long-term reliability, but lost the meaning that stops adverse current, gas-cooker still can be beaten to catch fire and cook.Existing gas meter, flow meter anti-backflow device all is to have installed a very thin plastics catch additional in the bottom, gas outlet of gas meter, flow meter basically, though this structure can prevent back flow of gas the short time, in case be stained with foreign matter on the catch; The combustion gas amount of leakage will heighten, and the combustion gas user just can just use gas always, is exactly both just not had foreign matter to be stained with in addition; This structure still has leakage rate to exist, and is of long duration, and gaseous-pressure and pipeline pressure in the gas meter, flow meter will reach balance; This moment, this device leakage rate will heighten; Table meter itself also just is equivalent to a little gas-holder of one 3～5 liters, and storage has been expired and the gas of pipeline with equal pressure in the table, and gas-cooker is easy to just beat catch fire.Gas-cooker is in a single day normal to be used, and the amount of leakage of this device will double, thereby does not have the effect of anti-adverse current.
Chinese patent document (the day for announcing: on November 3rd, 2004, notification number: CN 2653455Y) disclose a kind of integrated assembly type gas meter.Comprise watchcase, counter and gas meter movement, be about to counter and be arranged at air intake opening one side that gear trains such as gearing in the movement and counter drive link, backstop rotate to change and move 90 ° of angles.The counter drive link is connected with counter.The gas outlet of gas meter and air intake opening are located at respectively in two planes that are parallel to each other, and draft tube can be contained in several gas meter strings in the instrument box through air intake opening.
Technique scheme is for the ease of installation, centralized management, maintenance, replacing gas meter and facility thereof, reduces installation cost, increases work efficiency, and can mass-produce seriation integrated unit assembly type gas meter.And do not relate to for the anti-adverse current of gas-robbery resistence.
