Figure 1-3 As shown, the two-way opening and closing valve described in the present invention includes an electromagnet 4, a valve cover A1, a valve cover B3 and a valve body shell 2. The valve cover A1 and the valve cover B3 are respectively engaged at both ends of the valve body shell 2. The outer sides of the valve covers A1 and B3 are both mounted with electromagnets 4 through mounting holes. An iron sealing valve plate 12 is provided in the valve body shell 2, and an annular sealing sheet 16 is bonded to the outer edges of both sides of the iron sealing valve plate 12.

The other ends of the support springs 11 are respectively connected to one side of the inner wall of the valve cover A1 and the valve cover B3 through positioning plates 10. The valve cover A1 and the valve cover B3 are installed and fixed by tension screws 7 and locking nuts 8.

[0026] When in use, the annular sealing sheet 16 is made of PP material, which has high elasticity and good toughness, improves the close contact between it and the inner wall of the valve plate limiting groove 15, and significantly improves the leakage prevention effect. The overall valve body is easy to assemble and install and disassemble.
