DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] The diverter 6 is arranged between the valve body 5 and the hydraulic oil valve body seat 3. A plurality of diverter mechanisms 61 are evenly distributed on the diverter 6. A blocking cavity 62 is provided on the upper surface of the diverter 6. A movable hole 63 is provided through the middle of the diverter 6. The valve body 5 moves at the movable hole 63.

[0021] In addition, the valve body 5 includes a mushroom-shaped valve 51 on the upper part of the valve body 5, and a sealing plate 52 is fixedly connected to the outer wall of the mushroom-shaped valve 51.
