、これら内通路を連通させる弁孔を設け、この弁孔を開
閉可能に閉止する弁体と上記第１の通路もしくは第２の
通路内の圧力変動に応じて作動される圧力平衡機構とを
弁棒によって連結し、この圧力平衡機構により弁体を弁
孔に対して接離する方向に往復動させてこの弁孔の開口
面積を加減するようにした圧力制御弁において、上記弁
孔に弁座を設けるとともに、この弁座における第１の通
路および第２の通路に臨む両端部に夫々上記弁体が接離
可能に密接される弁座面を形成し、かつ弁体は弁棒に着
脱可能に連結するとともに、上記弁棒には、この弁棒に
対する弁体の連結位置を、弁孔を挾んだ一方側もしくは
他方側に位置決め固定する弁体支持部材を設けたことを
特徴とする自刃式圧力制御弁。A first passage and a second passage are provided in the valve box, and a valve hole is provided to communicate these internal passages, and a valve body that opens and closes the valve hole and the first passage or the second passage are provided. The valve rod is connected to a pressure balancing mechanism that is operated in response to pressure fluctuations in the valve, and the pressure balancing mechanism moves the valve body back and forth in the direction toward and away from the valve hole, thereby increasing the opening area of the valve hole. In the pressure control valve configured to adjust the pressure, a valve seat is provided in the valve hole, and the valve body is brought into close contact with both ends of the valve seat facing the first passage and the second passage so as to be able to come into contact with and separate from the valve seat. A valve seat surface is formed, and the valve body is removably connected to the valve stem, and the valve stem is provided with a connection position of the valve body with respect to the valve stem on one side or the other side across the valve hole. A self-cutting pressure control valve characterized by being provided with a valve body support member for positioning and fixing.
