我厂塑料气阀的结构是采用平面密封的杯形阀结构,阀片材料是纯聚四氟乙烯,加工方法是横压成型。塑料气阀的典型结构见图1与图2。 我们之所以选用聚四氟乙烯做阀片材料,是利用其极为良好的密封性和冲击韧性以及耐高温性。 阀片的结构采用杯形,是顾及了聚四氟乙烯强度低的主要弱点,杯形阀片与碟形阀片具有更高的强度和更 Our factory plastic valve structure is the use of flat-sealed cup-shaped valve structure, the valve plate material is pure PTFE, the processing method is horizontal pressure molding. The typical structure of the plastic valve shown in Figure 1 and Figure 2. The reason why we use PTFE as the valve material is to use its extremely good sealing and impact toughness and high temperature resistance. The structure of the valve is cup-shaped, taking into account the main weakness of PTFE low strength, cup-shaped valve disc and disc valve with higher strength and more
