Fig. 4 is an oblique view of the valve rod, and Fig. 5 is an enlarged view of part X of Fig. 3 (b). In FIGS. 3 and 4, the valve rod 12 is formed from a cylinder- 叩 w-circle shape and a cylindrical body 12A ′ and is formed concentrically with the i-th cylindrical body to have a shape that is greater than that of the first cylindrical body. The second body 12B has a large radius and is connected to the i-th cylindrical body. ° "On the side surface of the curved surface of the i-th cylindrical body 12A of the wide rod u, a groove 14 for inserting the spacer 13, a 孱 14 for η« m, and a screw portion for rotating and sliding are formed. In addition, as shown in FIG. 5, in a portion having a different radius to be connected to the second cylindrical body 12B, the angle of 帛 2 cylindrical body ΐ2β = the angle formed by the surface 17 with respect to the center axis of the valve rod is only a right angle small. The angle 'is also the composition of an acute angle. Both ends of the valve rod 12 are cut to have a wide portion 16 on both sides. — The wide part 16A on both sides of the square is used to fit the operating lever for rotating the valve rod 12. On the other side, the wide portion 16B is provided when the valve rod 12 is in the gas piping block M 315693 9 200521367 1 1 so that the through hole 5 is not blocked to ensure that the part slides and contacts the connector for ventilation. As described above, according to the gas piping according to the first embodiment of the present invention, since the functions of the switch of the ventilation part and the function of supplying and exhausting gas to and from the gas-tight container are concentrated on the block for gas piping, the external dimensions can be made smaller than conventional Gas piping: / Jn 〇 In addition, the gas piping blocks, valve rods and connectors that form the gas piping are all small in shape and can be manufactured by ordinary machining, so costs can be reduced. In addition, as the number of components decreases, the assembly time can be shortened, which can reduce assembly costs. Embodiment 2: Figs. 6 to 9 show a gas piping, a gas piping block, and a gas switch member according to the second embodiment of the present invention. In the figure, the same symbols as those in Fig. 丨 indicate the same or equivalent parts. , And its detailed description is omitted. In the gas piping of the second embodiment of the present invention, the storage space 6 of the gas piping block i is provided at a position different from that of the embodiment i, and a ball valve is used as the gas switching member. As shown in FIG. 8, the ball valve 19 used in the second embodiment is made of metal (for example, brass or aluminum). The ball valve 19 is formed into a substantially spherical shape, and has a through hole 22 as a gas passage in the center, and has a through hole as described above. Hole 22 is parallel to the groove 21. The storage space 6 of the gas piping block 1 is provided on the side where the ball valve is inserted and the communication path of the working hole 7 intersects (the bottom in the figure). That is, the gas piping system of Example 2 is as shown in FIG. 6, and the roughly spherical ball valve 19 is inserted into the side groove 2 丨 facing the operation hole 7 and inserted into the block for gas piping 315693 10 200521367 1 的 access space 6. As shown in FIG. 9, this ball valve 19 is shaped into a cylindrical shape by using a resin (such as urea resin), and a chamfered bushing 20 is applied to the inner side of the -side end face to face the storage space 6. Configuration in the depth direction. Then, 'a connector u having a piping connection function is mounted on the connector mounting portion. A pressure gauge 9 is mounted on the pressure gauge mounting portion 2. A piping (not shown) is mounted on the piping connection portion 18 of the above-mentioned connection 11. Lubricant is applied between the ball reader 19 and the bushing 20, and the operation (illustrated) is inserted through the operation hole 7 of the gas pipe block 1 and the front end of the operation rod is fitted into the groove 21 of the ball width 19. At 19, you can rotate the ball. At this time 'when the through hole 22 of the ball 19 and the through hole 5 inside the gas piping block core form a substantially vertical state, then the gold,, and dental holes 22 are locked (the state of the & the opposite) Open when it is approximately parallel (state in Figure 7).牙 孔 5 被 —As mentioned above, the gas piping according to the embodiment 2 of the present invention is the same, because the switch of the venting part and the sealing of the gas ^ exhaust function is concentrated in the gas piping block 丨The gas piping for fasting is even smaller. In addition, the shape can be smaller than the conventional ones. Moreover, because the outer shape of the gas piping blocks, bushings, etc., is small, it can reduce the cost by general mechanical benefits and balls. ^ f ′ Therefore, as the number of components is reduced, assembly can be shortened and assembly costs can be reduced. 1 ’So also (industrial availability) 11 1 15693 200521367 The present invention can be used for general gas piping such as gas-insulated switchgear, and has high availability.
