A second locking step 26 is formed at the boundary of the spindle receiving section 20, and a first locking step 23 is obliquely tapered inside the spindle receiving section 20 above the spindle receiving section 20. The first
The locking step 23 first includes a cylindrical portion (see a dotted line) having a predetermined thickness, which extends above the spindle receiving portion 20, and
After receiving 0, it is squeezed inward.

Since the screw portion 34 is formed on the lower surface, which is separated from the groove 32 by a predetermined distance, on substantially the entire outer peripheral surface of the spindle,
The spindle receiving portion 20 is screwed into a female screw portion 24 and is vertically movable.

The state in which the refrigerant is supplied to the first and second supply pipelines 16 and 18 is indicated by the alternate long and short dash line. The refrigerant is injected through the core 11 by opening the core cap 13 installed in the refrigerant inlet 12, and at this time, the taper portion 36 at the lower end of the spindle 30 is brought into close contact with the spindle seat portion 15 at the upper end of the second supply pipeline 18. When the refrigerant is present, the first supply line 18 is blocked because the second supply line 18 is blocked.
When only the supply pipeline 16 is injected and the spindle 30 is lifted to open the spindle seat portion 15, the refrigerant is injected into both the first and second supply pipelines 16 and 18. On the other hand, the spindle 30 comes into contact with the first locking step 23 of the spindle receiving portion 20 and stops when the spindle 30 moves upward. Even when the taper portion 36 at the lower end of the spindle 30 is in close contact with the seat portion 15, there is a storage space above the female screw portion 24, which contributes to the prevention of leakage of the refrigerant and the like.

効果がある。As described in detail above, in the service valve for a refrigerating machine according to the present invention, a screw portion is formed over substantially the entire outer peripheral surface of the spindle, and the screw portion has an upper portion at a predetermined distance from the screw portion. Since the groove is formed and the O-ring is received in the groove, when it is screwed into the spindle receiving portion, it is separated into the spindle receiving portion, the screwed portion of the spindle, and the O-ring sealing portion. Therefore, the leakage of the injected refrigerant or refrigerating machine oil is prevented primarily by the screwing portion and secondarily by the O-ring sealing section, so that the injected refrigerant or refrigerating machine oil is prevented from leaking. This has the effect of completely preventing leakage to the spindle receiving portion.

機械の故障発生率が最小化される効果がある。A first member is provided on the spindle receiving portion.
Since the locking step is formed obliquely inside the spindle receiving portion, the spindle for supplying the refrigerant to the first and second supply lines can be installed without using another spindle separation preventing ring. At the time of raising, even if the spindle rises too much due to the pressure in the valve body, it is restrained by the first locking stage and it is possible to prevent the spindle from coming off.
This has the effect of minimizing the machine failure rate.

There is also an effect that becomes easier.
