変形することになつた。 Such a gas meter is installed upstream of a gas meter that integrally measures the flow rate of city gas. The closure tightened by the gland packing is
The closure has become stuck to the Kotuku body due to long-term use, so in order to remove it from the Kotoku body during maintenance, conventionally, the prismatic shaft formed on the closure has to be removed using a pipe wrench or similar. Then, a large torque is applied to remove it, or the body of the Kotoku is hit with a hammer or the like to apply a shock, thereby breaking the strong bond between the closure and the Kotoku body.
As a result, the closure was damaged and the body of the kotuku was deformed.

体２に固着してしまう。 FIG. 1 is a perspective view of a pot 12 showing a state in which an obturator detachment device 1 according to the present invention is attached, and FIG. 2 is a sectional view thereof. A connection port 3 through which city gas flows in and a connection port 4 through which city gas flows out are formed in the Kotuku body 2, and a roughly conical closure 5 is formed between the connection ports 3 and 4. It's embedded. A rectangular prism-shaped shaft 6 is integrally molded with the closure 5 at the large-diameter end thereof. A gland packing 7 is interposed at the large diameter end of the closure 5, and the gland packing 7 is tightened by a gland nut 8. The gland nut 8 has an external thread 9
The gland nut 8 is threaded into an internal thread 10 formed in the lock body 2, and the shaft 6 is inserted gently through the gland nut 8. Grease is interposed between the outer circumferential surface of the closure 5 and the inner circumferential surface of the gland packing 7 to improve airtightness. If the pot remains closed for a long period of time, the closure 5 will become stuck to the pot body 2.
そこで、閉子５をコツク本体２から離脱するに
あたつては、まず軸６に固定部材１１を固定す
る。 Therefore, when removing the closure 5 from the lock body 2, the fixing member 11 is first fixed to the shaft 6.

The fixing member 11 is formed with an attachment hole 13 into which the shaft 6 is tightly fitted. This mounting hole 13 has a rectangular cross-section perpendicular to the axis, into which the shaft 6 fits tightly. Connected to the mounting hole 13,
A coaxial guide hole 14 having a circular cross section perpendicular to the axis is formed. An internal thread 15 facing the insertion hole 13 is formed in the fixing member 11 . A bolt 16 is screwed into this internal thread 15. The outer shape of the fixing member 11 is circular in cross section perpendicular to the axis, which is uniform in the axial direction.
The internal threads 15 are formed at intervals of 90 degrees in the circumferential direction. The bolt 16 has a fitting hole 17 into which a square spanner fits.

接またはごく近接して配置する。 To remove the closure 5 from the Kotuku main body 2, use the shaft 6.
Then, the fixing member 11 is fitted into the insertion hole 13 through the guide hole 14. Then, the fitting hole 17 of the bolt 16
The fixing member 11 is fixed to the shaft 6 by inserting a square spanner into the shaft 6 and pressing the tip of the bolt 16 against the shaft 6. This fixing member 11 is placed in contact with or very close to the gland nut 8.

体２から離脱することが容易である。 Then, loosen the gland nut 8 using a wrench or the like. With this, Grand Nut 8 becomes the first
Displaced upwards in FIGS. At this time, the gland nut 8 displaces the fixing member 11 and therefore the shaft 6 and the closure 5 upward in FIGS. 1 and 2. In this way, the closure 5 is detached from the lock main body 2. The force required to loosen the nut 8 is small due to the screw action between the outer screw 9 and the inner screw 10, and at this time, the force required to loosen the nut 8 is small due to the screw action between the outer screw 9 and the inner screw 10. A large upward force acts. Therefore, it is easy to remove the closure 5 from the lock main body 2.

易に離脱することができる。 As described above, according to the present invention, when loosening the gland nut, the fixing member fixed to the shaft of the closure is displaced so as to separate from the closure body 2, thereby causing the closure to separate from the closure body 2. Since it is detached, no large torque is applied to the closure 5, and no impact force is applied to the closure body. Therefore, the closure can be closed without damaging the closure 5 or deforming the closure body. The child can be easily removed from the Kotuku body.
