With the improvement of living standards, the energy used at home has gradually transformed from traditional coal to traditional gas and natural gas.Therefore, each household is equipped with a gas meter.In addition to controlling gas flowing outward distribution, the gas meter can also record the amount of gas we use, so the gas meter is a very convenient instrument in home life.What do you think of the gas meter?How to install the gas meter?Let Xiaobian take everyone to understand.
Principles of gas meter use
The gas meter uses the pressure difference between the gas during the flow of the gas as the power, and controls the distribution of the gas flow from the relative positions of the valve seat and valve cover.The membrane box of the gas meter is composed of the same two gas measurement rooms. Each gas measuring room is divided into two identical small measuring rooms by a soft membrane.When the distributed gas enters the four small measuring rooms in turn, pushing the films free swing, the movement of the film component drives the connecting mechanism (the double crank handle joystick) through the joystick and the rotation motion of the valve cap is to control each measurement roomInflatomic and exhaust, the gas meter is continuously circulated. At the same time, the eccentric rotation of the connecting mechanism to rotate the gear to drive the mechanical unidirectional counter by the transmission of the gear, and finally display the exhaust volume of the gas meter through the counter.
How to look at the gas meter
Household membrane -type gas meter: It is the kind of word wheel, generally the first five (black) and the last three (red), the whole value of black, and red is the value behind the decimal point.This is easy to read, and directly minus the value from the previous value, get the result of the desired.Of course, the amount of gas is recorded here, not the payment amount.
Smart gas meter: There are many smart gas meters, such as wireless remote gas meters, Internet of Things gas meter, IC card gas meter, etc.The method of reading the value is similar. If there is a liquid crystal display, the number of direct read is sufficient. If it is a word wheel, it is consistent with the reading method of the membrane gas meter.
Old -style pointer -type gas meter: This gas meter looks more complicated, and there will be a sign of 1,10,100 and other values ??on the dial. This means what is the value of this beginning.For example, the value on the 10 bits is 2, that is, 20, 100 are 3, 300 and so on.There is no need to record the value of the decimal point. Read all values ??in this way and follow the values ??when the meter was copied last month.
How to install the gas meter
The gas meter can only be placed horizontally on the bracket and must not be tilted. The vertical deviation of the table is 1cm.The entrance and export pipes of the gas meter are used for steel pipes or lead pipes. The threaded connection should be tightly connected. After the lead tube is bent, it becomes an arc shape.The horizontal pipe slopes in front of the surface are towards the riser, and the horizontal pipe slopes of the surface of the surface.The live joints of the low -scale stove -level tube are not set in the stove board.When the gas meter inlet and export are connected to the surface with a single tube connector, the connection direction should be paid to prevent wrong installation.Single tube connecting side -end penta, the trachea is connected at the top.The rubber sealing ring must be installed at the lower end of the lower end.When the gas tube of the gas meter is on both sides of the table, the connection direction should be paid attention to.Under normal circumstances, people face the air intake pipe on the left side of the table disk, and the right side of the air pipe.When installing, it should be installed according to the product manual of the gas meter, so as not to install it wrong.After the gas meter is installed, strict tests should be performed.The test medium is compressed with compressed air, the pressure is 300mm high water column, and the 5min internal pressure drop is not more than 20mm water column.
