Beschreibung
Zusammenfassung:	The check valve comprises a valve pipe, the outer portion of the valve pipe is in threaded connection with a first threaded ring, a first hand wheel is fixedly installed on the outer wall of the first threaded ring, one side of the first threaded ring is fixedly connected with a first extrusion cylinder, and the two ends of the valve pipe are fixedly connected with sealing rings. A connecting pipe is arranged on one side of the sealing ring in an extrusion mode, and an extrusion sealing ring is fixedly connected to the outer side of the connecting pipe. According to the check valve convenient to disassemble, when the check valve is disassembled, firstly, a second hand wheel drives a second threaded ring to rotate, then a second extrusion cylinder is removed from the outer side of a first extrusion cylinder, then a first wheel is held by hand to rotate a first threaded ring outside a valve pipe, and then the first extrusion cylinder is removed from the outer side of a connecting ring; the pressure between the
