In order to prevent the first valve core plate 2 and the second valve core plate 3 from rotating synchronously, as shown in fig. 1 and fig. 2, the valve seat 4 is provided with positioning holes 141, and the lower end surface of the first valve core plate 2 is fixedly provided with positioning pillars 22 inserted into the positioning holes 141, in this embodiment, four positioning holes 141 and four positioning pillars 22 are provided and are uniformly distributed along the circumferential direction of the first valve core plate 2, so that the first valve core plate 2 and the valve seat 14 can be prevented from rotating relatively.

Because axle sleeve 8 and closing plate 4 belong to hard material mostly, the sealed effect between axle sleeve 8 and the closing plate 4 is relatively poor, in order to improve sealed effect, in this embodiment, as shown in fig. 2 and fig. 3, sealed hole 41 has been seted up on closing plate 4, sealed hole internally mounted has seal cover 9, seal cover 9 is the rubber material, the inner wall of seal cover 9 with the outer wall interference fit of axle sleeve 8, the outer wall of seal cover 9 with the lateral wall interference fit of sealed hole 41 utilizes seal cover 9 to improve the sealed effect of axle sleeve 8 and closing plate 4.

When the sealing plate 4 is mounted on the mounting seat 15, when the medium pressure inside the valve body 1 is too high, the sealing plate 4 can be pushed to move upwards, at this time, the medium can flow outwards through a gap between the sealing plate 4 and the mounting seat 15, in order to strengthen the fixation of the sealing plate 4, in this embodiment, as shown in fig. 1, the upper end of the valve core cavity 11 is communicated with the outside, an end cover 7 with a downward opening is mounted at the upper port of the valve core cavity 11, the side wall of the end cover 7 is assembled with the inner wall of the valve core cavity 11 through threads, and the lower end of the end cover 7 abuts against the upper end face of the sealing plate 4, so that the sealing plate 4 can be prevented from moving upwards, and the medium can be prevented from flowing out.
