Thus, the valve body 6 does not come out of the communication portion 11, and the state where the valve body 6 is installed in close contact with the seal member 9c and the interposed member 9d can be maintained.

  Further, when the valve body 6 is installed in the communication place 11, the position of the discharge hole 13 provided in the valve body 6 corresponds to the position of the through hole 10 provided in the communication place 11 as described above. And the inside of the valve body 6 and the derivation | leading-out part 5b come to communicate. As a result, the air accumulated in the valve body 6 can be discharged to the lead-out portion 5b through the discharge hole 13 and the through hole 10, and when discharging foreign matters to the outside, the discharge hole 13 and the through hole 10 are discharged. The flow velocity of the fluid increases with the flow of fluid between the communication portion 11 and the lead-out portion 5b, so that the foreign matter staying in the precipitation portion 5a can be wound up and efficiently discharged to the outside. it can.
