Beschreibung
Zusammenfassung:	According to the technical scheme, the pilot pneumatic control double-interlocking air valve is characterized by comprising a first valve body, a second valve body and a third valve body, the first valve body is provided with an air source inlet, a first valve cavity and a second valve cavity; the air source air inlet is communicated with the first valve cavity and the second valve cavity; a first valve element assembly is arranged in the first valve cavity. A second valve element assembly is arranged in the second valve cavity. A second valve body; the second valve body is mounted on the first valve body; the second valve body is provided with a first air outlet and a second air outlet which are used for being connected with an air cylinder. The first air outlet is communicated with the first valve cavity; the second air outlet is communicated with the second valve cavity; the plane sealing structure has the advantages that abrasion of a sealing piece can be reduced in a plane sealing mode, and the plane sea
