When a failure occurs in the operation of the mechanism, the machine equipment must stop operating and take time off to clean the dust, which results in a lot of time and cost loss. In addition, the valve opener is known to have a complex structure, is difficult to assemble, and easily consumes a lot of assembly time. The present invention mainly comprises: a valve opener, which is made of non-metal fiber-reinforced plastic (fiber-reinforced plastic The valve supporter is made of FRP (FRP), and the valve supporter includes a plurality of integrally formed assembly parts, that is, each assembly part is arranged at the four corners of the valve supporter at a 45-degree angle relative to the horizontal, each assembly part is generally in an inverted L shape, and the four assembly parts are arranged symmetrically in the upper, lower, left and right directions; then each assembly part is respectively provided with a A shaft assembly hole, and a connecting groove is provided on the adjacent side of the shaft assembly hole. A combination part is provided at the center of the top end of the valve supporter, and a bottom edge is formed at the bottom. The two assembly parts on the bottom side protrude from the bottom edge. A side concave is formed at the waist of both sides of the valve supporter, and a central through hole is provided in the center of the valve supporter, and a plurality of assembly holes are distributed around the central through hole.

The valve supporter of the present invention is made of non-metallic fiber-reinforced plastic material. When it comes into abrasive contact with the valve seat of a metal component, it will not generate a lot of dust due to abrasive contact, and the sharp noise generated by the friction between metals is greatly reduced. The present invention also reduces the generation of dust and will not cause dust to be stuck in the bearing ball or ball inside the machine, thereby preventing the occurrence of failures in the operation of the mechanism and improving the smoothness of the operation of the machine equipment. The valve supporter of the present invention is simple in structure due to its one-piece molding, and the assembly of the matching components does not take a lot of time, saving labor costs.
