Description

[Detailed description of the invention] Industrial application field This invention relates to the structure of a gas meter that measures and displays the amount of gas used in general households. ,
The present invention relates to an integration display structure for a gas meter that converts this reciprocating motion into rotational motion and transmits this rotational motion to a counter section to integrate and display the gas flow rate.

BACKGROUND TECHNOLOGY This type of gas meter has conventionally been used, for example, as shown in FIGS. 8 and 9, to send gas flowing in from an inlet 1 to a metering section 2, and to discharge the gas through the metering section 2 to an outlet 3. At the same time, the gas passing through the metering section 2 causes reciprocating motion, the crank section 4 converts the reciprocating motion into rotational motion, and the rotational motion is transmitted to the counter section 5 to display the integrated gas flow rate. It was hot.

However, as shown in the figure, in this conventional gas meter B, the counter part 5 is separately mounted with the counter part 5 protruding from the front of the upper case 6 of the crank part 4, and the display mechanism is housed horizontally in the counter case 7 of the counter part 5. and calculate the cumulative flow rate in cubic meters (m ³ ).
It had a horizontally long display with units and liters displayed.

Problems to be Solved by the Invention Therefore, according to the conventional gas meter B, the counter case 7 is purposely mounted in a protruding manner, which requires additional space on the front side, and furthermore, the gas flow rate is displayed in an integrated manner horizontally. Due to the structure, as the number of digits in the counter section 5 increases, more space is required in the left and right directions, resulting in an overall increase in size. This had the disadvantage that it was impossible to make the gas meter more compact.

Therefore, the object of this invention is to form a gas meter having a counter section as described above compactly without any complicated structure.

Means for Solving the Problems Therefore, this invention sends the gas flowing in from the inlet 24 to the metering section 10 and discharges it from the metering section 10 to the outlet 23, and at the same time, the gas passing through the metering section 10 is In a gas meter A that generates reciprocating motion, converts the reciprocating motion into rotary motion, and transmits the rotary motion to a counter section 30 to display the integrated gas flow rate, the measuring section 10 is roughly divided into two measuring sections 12 and 13. A storage space 21 is formed between the metering parts 12 and 13, and the counter part 30 is provided in the storage space 21 in the vertical direction with respect to the gas meter A.

Function: Therefore, the counter section 30 is connected to the gas meter A.
The gas flow rate is displayed vertically in the metering section 10 of the meter.

Embodiments Hereinafter, this invention will be explained specifically and in detail according to embodiments shown in the drawings.

1 to 3 show a gas meter to which this invention is applied. What is indicated by the reference numeral 10 in the figure is
This is the measuring section. The measuring section 10 is divided into two large measuring sections 12 and 13 by a vertical partition wall 11, and these two measuring sections 12 and 13 are further divided into two chambers by diaphragms 14 and 15, respectively, to provide a total of four chambers. Measuring chambers 12a, 12b, 13a, 13b
form. The diaphragms 14 and 15 are sandwiched between a pair of membrane plates 16 and 16 or 17 and 17, respectively. The pair of membrane plates 16 and 17 are
They are connected to wing shafts 18 and 19, respectively. Two wing axes 1
8 and 19 both penetrate the upper surface of the measuring section 10 and protrude into the crank section 20.

Furthermore, the measuring section 10 is formed with a storage space 21 between the measuring parts 12 and 13 by the vertical partition wall 11. A gas outflow passage 22 is formed in this storage space 21 on the back side of this gas meter A (upper side in FIG. 2). The outflow passage 22 passes through the gas meter A in the vertical direction (vertical direction in FIG. 1). Thus, an outlet 23 is opened at the lower end of this outlet passage 22. Upper case 20 of the crank part 20
An inlet 24 is provided above the outlet passage 22 on the extension line of the outlet passage 22, and the inlet 23 and the outlet 23 are arranged on the same line via the outlet passage 22. And, above the outflow passage 22 of this measuring section 10,
A valve seat 25 is provided, and a valve 27 is mounted rotatably about a valve shaft 26 on the valve seat in the upper case 20a. Thus, the reciprocating motion of the diaphragms 14, 15 in the metering portions 12, 13 is controlled by the blade shaft 1.
8 and 19 to the crank part 20, and the link mechanism 28 converts the reciprocating motion into rotational motion, and the valve seat 2
Rotate valve 27 on 5. This rotational motion is transmitted to the counter section 30 via the wheel train 29 of the crank section 20.

By the way, this counter section 30 is similar to the measuring section 10.
It is provided in a storage space 21 formed inside. The counter section 30 is provided vertically in parallel with the outflow passage 22 on the front side (left side in FIG. 1) of the lower case 31, and displays the flow rate of gas passing through the display window 32. Therefore, the counter section 30 is constructed by vertically assembling each of its constituent parts, as shown in exploded view in FIG.

That is, the counter section 30 has a first number wheel 35 between the two plate-shaped upper and lower counter sections 33 and 34.
The numbers from a to the last number wheel 35b are arranged in a vertically overlapping manner. Then, as shown in the figure, the number axle 37 is sequentially inserted into the upper counter frame 33, each number wheel 35, the transmission gear 36, and the lower counter frame 34, and the number axle 37 is inserted into each number wheel 35 and the transmission gear 34. support. An L-shaped arm 38 is fixed to the upper end of the numerical axle 37, and as shown in FIG. is transmitted. The numerical axle 37 has a milled surface 40 on one side of its lower end to form a half-moon shape in cross section, and a transmission gear 36 also has a half-moon shape.
The transmission gear 36 is fitted into the center hole 36a of the transmission gear 36, and rotation is transmitted to the transmission gear 36. Further, an E ring 41 is fitted to the lower end of the numerical axle 37 to prevent it from coming off. An adjustment gear 42 rotatably attached to the lower counter frame 34 meshes with the transmission gear 36. The adjustment gear 42 consists of upper and lower gears 43 and 44, with the lower gear 44 meshing with the transmission gear 36.
The upper gear 43 meshes with the first number wheel 35a,
The rotation of the transmission gear 36 is transmitted to the first number wheel 35a. Therefore, by appropriately changing the number of teeth of this two-stage adjustment gear 42, the first numerical wheel 35
By adjusting the rotation transmitted to a, instrumental error adjustment in gas flow rate measurement is performed. A pinion 45 is engaged between each number wheel 35,
Rotation is transmitted sequentially from the bottom to the number wheels on the top. Therefore, the gas flow rate is integrated while sequentially transmitting the rotation of the first number wheel 35a to the intermediate number wheels. The pinion 45 is rotatably supported between the counter frames 33 and 34 with a pinion shaft 46 inserted therethrough. pinion shaft 4
6 is attached to the upper and lower counter frames 33 and 34 by fitting E-rings 47 and 48 into both ends thereof. Furthermore, each support piece 50 of the support member 49 is inserted between each number wheel 35 stacked up and down in this way. Then, the number wheel 35 is placed on the support piece 50 so that the load of the number wheel 35 is not applied to the first number wheel 35a. As shown in the figure, the support member 49 includes a plurality of support pieces 50 rising from the base plate 51.
An escape recess 52 for the numerical axle 37 is provided at the tip of the numeral axle 37. Further, the support member 49 is screwed to the upper counter frame 33 using a mounting piece 53 formed by bending the upper end of the base plate portion 51. A bifurcated mounting piece 54 is provided at the lower end of the base plate portion 51, and the mounting piece 54 is screwed to the counter frame 34 on the lower side. Therefore, since the number wheel 35 is supported by the support member 49 in this way and the load of the upper number wheel 35 and pinion 45 is not applied to the first number wheel 35a, rotation of the first number wheel 35a is prevented. Stable rotation can be obtained with almost no frictional resistance. Then, the name plate 55 is placed over these number wheels 35 and pinion 45.
are screwed to the counter frames 33 and 34. The name plate 55 is provided with elongated holes 56 and 57 in the vertical direction along the number wheel 35 to indicate the gas flow rate in cubic meters "m ³ " and liters, respectively.

Therefore, as shown in FIG. 1, when gas enters the crank part 20 from the inlet 24, the gas is sent into the measuring part 10 through the valve 27 and moves through the diaphragm 14 or 15 in the measuring chamber. Then, the gas in the other metering chamber is discharged from the outlet passage 22 through the outlet 23 through the valve 27 again.
At the same time, the movement of the diaphragms 14 and 15 is controlled by the wing axis 1.
8, 19 to the crank section 20, and the link mechanism 28 converts the reciprocating motion into rotational motion to rotate the valve 27, and the rotational motion is transmitted from the rotating shaft 39 via the wheel train 29 to the counter section. 30, the number wheel 35 is sequentially rotated, and the flow rate of gas passing through the display window 32 is displayed in an integrated manner.

In addition, the gas meter A in this invention mentioned above
As shown in the figure, the counter section 30 is replaced by a number wheel 35,
It is composed of a pinion 45, etc., and mechanically integrates and displays the gas flow rate. However, as long as the counter section can be arranged in the vertical direction, this invention can be implemented using a liquid crystal panel that magnetically detects the rotation of the valve 27 and attaches it to the electronic counter 60, as shown in FIGS. 5 and 6, for example. The present invention can also be directly applied to a gas meter equipped with an electronic display mechanism such as a liquid crystal display at 61.

Furthermore, the above-mentioned gas meter of this invention had a structure in which the gas flow rate was displayed in cubic meters (m ³ ) and liters (liters) in a line in the vertical direction. As long as they are provided in the vertical direction, the display structure can also be arranged in two horizontal rows.

Effects of the invention According to this invention, the structure is such that the counter part is housed vertically in the storage space provided between the two measuring parts of the gas meter, so there is no problem of only the counter part protruding and taking up extra space. Even if the number of digits on the counter display increases, there is already enough space in the vertical direction of the metering section, so there is no need to add extra space. It becomes possible to realize the
