Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0015] Such as figure 1 and figure 2 An anti-corrosion and anti-collision steel ball valve structure is shown, including a main valve body 1, an auxiliary valve body 2 is arranged inside the main valve body 1, and a valve seat 3 is arranged on the auxiliary valve body 2, so There are two valve seats 3, a sphere 4 between the two valve seats 3, a valve stem 5 is arranged on the top of the sphere 4, and the valve stem 5 is arranged on the main valve body 1 On the valve stem seat 6, the surface of the main valve body 1 is provided with a PE anti-corrosion and anti-collision layer 7. The PE anti-corrosion and anti-collision layer 7 is integrally formed by injection molding. The thickness of this anti-corrosion and anti-collision layer is not less than 5mm, which effectively prevents The metal surface of the valve is corroded and collided; the inlet and outlet of the a...
