To provide a pressure regulation valve capable of suppressing damage of function of the pressure regulation valve and suppressing the occurrence of noise accompanying seating of a valve body.SOLUTION: A pressure regulating valve 10 for a drain pipe regulates a pressure in the drain pipe and includes: a housing 11 having a valve seat 23 formed on a circumference of a communication hole 22 for communicating a vent pipe 100 which is branched from the drain pipe and is extended with an external part and a support cylinder part 27 arranged in the communication hole 22; a shaft part 16 which can be displaced along a shaft line direction in the support cylinder part 27; a valve part 18 which is abutted on the valve seat 23 by gravity, closes the communication hole 22 and, on the other hand, is displaced so as to be separated from the valve seat 23 by a pressure difference between a pressure in the drain pipe and a pressure of the external part; and a valve body 15 integrally molded with soft resin. On the shaft part 16, a regulation part 17 which regulates the maximum displacing quantity of the shaft part 16 is provided by restraint on the support cylinder part 27.SELECTED DRAWING: Figure 3
【課題】圧力調整弁の機能が損なわれることを抑制でき、且つ弁体の着座に伴って異音が発生すること。【解決手段】排水管用圧力調整弁１０は、排水管内の圧力を調整するものであり、排水管から分岐して延びる通気管１００と外部とを連通する連通孔２２の周囲に形成された弁座２３及び連通孔２２内に配置された支持筒部２７を有するハウジング１１と、支持筒部２７内をその軸線方向に沿って変位可能な軸部１６、及び重力により弁座２３に当接されて連通孔２２を閉塞する一方、排水管内の圧力と外部の圧力との圧力差によって弁座２３から離間するように変位する弁部１８を有し、軟質樹脂により一体成形された弁体１５とを備えている。軸部１６には、支持筒部２７に係止されることで軸部１６の最大変位量を規制する規制部１７が設けられている。【選択図】図３
