Claims

[Scope of utility model registration request]

A valve box 1 is provided with a pair of opposing inlets 3 and an outlet 4, and an outlet 5 in a direction perpendicular to the inlets and outlets, respectively, communicating with a valve chamber '2, and having a valve hole 7 in one direction in the valve chamber 2. In the sampling case 7'<lub in which the body 6 is inserted, the inner diameter of the valve hole 7 is set to 1, and the distance from the bottom point d' of the end face of the valve hole 7 opposite to the bottom point d of the outlet side seat ring 12 to the circumferential surface of the valve body 6e is If we take an imaginary string m in the direction of the outlet 5 and have a length that matches the inner diameter 1 above, and draw an imaginary line n parallel to the inner surface of the outlet 5 from one end e of the chord m on the outlet 5 side, , a sampling valve characterized in that the inner peripheral surface f of the seat ring 13 attached to the outlet 5 is located closer to the virtual line n.
