回動操作されるようになっている。2. Description of the Related Art As a conventional gas plug with an inspection hole, for example, there is one described in Japanese Utility Model Laid-Open No. 64-11478.
As shown in FIG. 12, the gas plug described in this publication has an inflow port 1a, an outflow port 1b and a plug insertion hole 1c formed inside a plug body 1, and a plug body in the plug insertion hole 1c. 2 is rotatably stored. Inside the plug body 2, a gas hole 2a is formed which penetrates from the outer peripheral surface of one side portion to the outer peripheral surface of the other side portion. Then, as shown in the drawing, when the openings at both ends of the gas hole 2a coincide with the openings of the inlet 1a and the outlet 1b in the plug insertion hole 1c, the inlet 1a and the outlet 1b are formed.
Communicate with each other through the gas hole 2a, whereby the gas plug is opened. On the other hand, from this state, the stopper body 2 is rotated by about 90 °.
When rotated, both end openings of the gas hole 2a are circumferentially separated from the inflow port 1a and the outflow port 1b, the inflow port 1a and the outflow port 1b are blocked by the plug body 2, and the gas plug is closed. . The stopper 2 is designed to be rotated by a handle (not shown).

とができる。Further, an inspection hole 1d extending from the inner peripheral surface of the plug insertion hole 1c to the outer surface is formed in the stopper body 1, and a communication hole 2b extending from the inner peripheral surface of the gas hole 2a to the outer peripheral surface is formed in the stopper body 2. Has been formed. The inspection hole 1d and the communication hole 2b are
When the stopper 2 is rotated to the open position, the stopper 2 is communicated. In the communicating state, the stopper 3 is removed, the pressure gauge is connected to the inspection hole 1d, and the main stopper is opened to close the gas equipment. Thus, the gas pressure can be inspected. Further, by closing the main plug and the gas device, a leak test from the main plug to the gas device (hereinafter, referred to as a total gauge) can be performed. Further, when the plug 2 is rotated to the closed position, the inspection hole 1d is blocked from the inflow port 1a, and is connected to the outflow port 1b through the gas hole 2a and the communication hole 2b. Therefore, it is possible to perform a leak test from the gas plug to the gas equipment (hereinafter, referred to as a single gauge).

事故を招くおそれがある。By the way, since the inspection hole 1d and the communication hole 2b communicate with each other when the gas stopper is opened, if the stopper 3 is forgotten to be closed, a large amount of gas may flow out from the inspection hole 1d, leading to a serious accident. There is.

As shown in FIG. 13, the inspection hole 1d and the communication hole 2b are arranged so as to be offset from each other so that they do not communicate with each other when they are opened.
As shown in (B), there is one in which the stopper 2 is rotated from the open position to the closed position side by a predetermined inspection angle (for example, about 15 °) so as to communicate with each other when it is in a half-opened state (actual opening). 64
-38368). According to this gas plug, the inspection hole 1d and the communication hole 2b do not communicate with each other when they are opened, so that the above problem can be prevented.

【発明が解決しようとする課題】しかしながら、検査孔
１ｄと連通孔２ｂとの開時における位置をずらしたガス
栓は、プロパンガスの調整圧の測定にはほとんど用いる
ことができないという問題があった。However, there is a problem in that the gas plug, in which the inspection hole 1d and the communication hole 2b are displaced when they are opened, can hardly be used for measuring the adjusted pressure of propane gas. .

ど用いることができなかったのである。That is, in the above-mentioned conventional gas plug with an inspection hole, as is apparent from FIGS. 13 (A) and 13 (B),
The communication state between the gas hole 2a and the inflow port 1a and the outflow port 1b is different between the time of opening and the time of inspection, and the flow resistance differs accordingly. This difference in flow resistance does not pose any problem when measuring gas pressure with the gas flow stopped, as in city gas pressure measurement.
When measuring the gas pressure in the state of flowing gas, like the measurement of the adjusted pressure of propane gas, the difference in the flow resistance between the measured gas pressure and the gas pressure during actual use in the open state is Cause a corresponding error. For this reason, the conventional gas plug with the inspection hole could hardly be used for measuring the adjusted pressure of propane gas.

In particular, when the depth of each notch is set to the depth as in the invention according to claim 4, the communication area can be increased and the flow resistance between the inlet and the outlet and the gas hole can be reduced. can do. further,
By increasing the width of the openings at both ends of the gas hole, the communication area between the gas hole and the inflow port and the outflow port at the time of opening and measuring the gas pressure can be correspondingly widened. Particularly, when the width of the opening of the gas hole is set to the depth as in the invention according to claim 6, the communication area can be made wider and the flow resistance between the gas inlet and the gas outlet can be increased. Can be made smaller. The operation of the invention according to claim 7 is the same as that of the invention according to claim 1, and therefore description thereof will be omitted.

It allows you to do one-sided gauges. Of course, if the handle 15 can be rotated by approximately 90 ° from the open position to the side opposite to the closed position, the inspection hole 11d can be connected to the communication hole 12b and the gas hole 1.

一になる。In the above gas stopper, when the handle 15 is positioned at the open position, the openings at both ends of the gas hole 12a are closed by the leading angle θ 2 with respect to the openings at the inlet 11a and the outlet 11b. Since it deviates in the direction from the side toward the open position, the inspection hole 11d and the communication hole 12
When the handle 15 is positioned at the open position, the inlet 11a and the outlet 11 and the gas hole 12a are communicated with each other when the gas pressure is measured while the gas pressure is measured. Compared with the conventional gas plug that is made to coincide with the opening of the above, the communication state when the handle 15 is positioned at the open position can be brought closer by the amount corresponding to the leading angle θ 2 . Therefore, according to this gas plug, the difference between the measured adjustment pressure and the adjustment pressure during actual use can be reduced. In particular, when the leading angle θ 2 is set to approximately half the inspection angle Θ, the positional relationship between the inlet 11a and the outlet 11b and the gas hole 12a is such that the inlet is open and the gas pressure is measured. 11a and the outlet 11b are symmetrical with respect to the axis, so that the inlet 11a and the outlet 1
The communication state between 1b and the gas hole 12a can be made substantially the same during actual use and during gas pressure measurement. Therefore, the adjusted pressure during measurement and the adjusted pressure during actual use become substantially the same.

It is a figure similar to (H). In this embodiment, notches 12c are formed on both sides of both ends of the gas hole 12a. Each notch 12c has a depth in the outer peripheral surface of the plug 12 that is substantially equal to the amount of displacement of the gas hole 12a. Therefore, when the handle 15 is positioned at the open position, the bottoms of the cutouts 12c, 12c on the closed position side are substantially continuous to the respective side parts on the closed position side of the inflow port 11a and the outflow port 11b, and the handle 15 is opened. When the inspection hole 11d and the communication hole 12 are made to communicate with each other by rotating from the inspection angle Θ, the bottoms of the cutouts 12c, 12c on the open position side are the side parts on the open position side of the inflow port 11a and the outflow port 11b.

The communication area with 2a can be widened in the same manner as in the above example. However, by doing so, the side portions on the open position side or the closed position side of the inflow port 11a and the outflow port 11b at the time of opening and gas pressure measurement can be made. The gas flow is disturbed by projecting to the inside of the gas hole 12a. In addition, the circumferential length between the notch 12c and the communication hole 12b, that is, the seal length is shortened. Therefore, it is desirable to set the depth of the notch 12c to the depth as described above.
