Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] like Figure 1-3 As shown, the self-adaptive two-way floating valve seat structure provided by the present invention includes a valve body 1, and a valve seat 2 and a spherical cap 3 that cooperate with each other are arranged in the valve body 1, and the spherical cap 3 is connected to the ball 15, and also includes a The valve body 1 is close to the pressure plate 4 on the side of the spherical crown. The valve seat 2 is located between the pressure plate 4 and the valve body 1, and there is an axial clearance between the pressure plate 4 and the valve body 1 on both sides. Compressed first spring 5, second spring 6, a plurality of first springs 5, second spring 6 are evenly distributed along the circumferential direction on both sides of the valve seat, the end of the first spring 5 is against the valve body 1, the second T...
