本发明专利技术提供一种减压阀,隔膜杆经由隔膜保持件保持在隔膜上,该隔膜被夹持在本体和盖部之间,阀体可落位于阀座上,且设在阀轴的中间部,该阀座固定配置在本体内,在中央部开口有阀孔,阀轴的一端部可装卸地连接于隔膜杆,另一端部可滑动地嵌合在设于本体侧的引导孔中,在所述减压阀中,阀动作组件(120)通过预先组装以下部分而构成:阀座部件(100),其设有阀孔(111)和阀座(112);引导部件(106),其压入在阀座部件(100)中,并具有引导孔(105);和阀轴(114),其设有阀体(113),阀动作组件(120)以这样的状态安装在本体(34)上:即,使阀轴(114)的一端从阀孔(111)突出、并且使阀轴(114)的另一端部可滑动地嵌合于引导孔(105)中的状态。由此可以实现加工成本的降低和组装性的提高。

Pressure reducing valve and gas regulator

The present invention provides a pressure relief valve, diaphragm diaphragm retainer rod through the remains in the diaphragm, the diaphragm is clamped between the body and the cover body, can fall in the seat, and is arranged at the middle part of the valve shaft, the valve seat fixed in the body, in the central part of the opening end of the valve hole. The valve shaft is detachably connected to the diaphragm rod, the other end of the guide hole is slidably fitted on the side of the main body, the pressure relief valve, valve assembly (120) formed by the following parts: pre assembled seating parts (100), which is provided with a valve hole (111) and the seat (112); the guide member (106), the pressure in the valve seat member (100), and has a guide hole (105); and the valve shaft (114), which is provided with a valve (113) valve assembly (1. 20) in such a state is installed on the main body (34): namely, the valve shaft (114) at one end of the valve bore (111), and the outstanding valve shaft (114) and the other end is slidably fitted to the guide hole (105) in the state. Thus, the processing cost can be reduced and the assembly performance can be improved.
