ック弁付絞り弁。[Claim for Utility Model Registration] A check valve body 7 provided in a valve chamber 6 formed in the main body 1 is biased toward the valve seat 3a by a spring 9, and the inlet port 1 is
2 to the outlet port 13 in an uncontrolled manner,
A flow rate adjustment means 4, which can be screwed and fixed to the main body 1, is fitted into a fitting hole 7a provided in the check valve body 7 and forming a part of the fluid passage, so that the flow rate adjustment means 4 can be moved forward and backward. 4
In a throttle valve with a check valve, the fluid is throttled in the passage between the outlet port 13 and the inlet port 1'2 in a phase η positional relationship with the check valve body 7, and the fluid is allowed to flow in a controlled state. A check valve characterized in that the flow rate adjustment means 4 has two separate structures: a flow rate adjustment part 5 that fits into the check valve body 7 and an adjustment screw part 8 that screws into the main body 1. With throttle valve.
