Abstract

[Application of the article] This invention relates to a "sealing member for a gate valve", which is a composite sealing material suitable for use in, for example, semiconductor manufacturing devices. As shown in the A-A cross-sectional view, the composite sealing material of this invention is composed of a first member made of rubber and a second member made of a synthetic resin that is harder than the first member made of rubber. The first member and the second member are used in a combined state, or are used by connecting the two members with an adhesive. When this invention is installed in a sealing groove, the sealing is ensured by the first member made of rubber arranged on the outer periphery of the sealing groove. In addition, by configuring the second member made of synthetic resin on the inner circumference of the sealing groove, the plasma resistance or corrosive gas resistance that cannot be fully exerted by the first member is ensured. ;【Creative Features】;This creation is a joint (I) appearance design of the joint new style of the "Sealing Component for Gate Valve" No. 98302336. As shown in the three-dimensional diagram, the A-A section line section view and its A-A section line partial enlarged section view, the main body of this creation is shown in each view of the first member and the second member at the same time, presenting a special shape of a first member with a larger diameter and a second member with a smaller diameter than the first member, which is an overall ring-shaped body. The outer peripheral surface of the first component is generally formed with an outer convex edge protruding outward in an arc shape in the middle, and the inner peripheral surface is generally formed with an inner convex edge protruding inward in a trapezoidal shape in the middle, and the inner peripheral surface is generally formed with an inner convex edge protruding inward in a trapezoidal shape, and the inner and outer convex edges form a cross-shaped cross-section as shown in the partial enlarged cross-sectional view of the A-A section line. The outer peripheral surface of the second component is generally formed with an outer concave edge having a slightly trapezoidal groove shape in the middle, and the inner peripheral surface is generally formed with an inner convex edge having a trapezoidal convex shape with a larger inclination angle. As shown in the partial enlarged cross-sectional view of the A-A section line, the inner convex edge of the first component and the outer concave edge of the second component are in a state of close fit. As shown in the reference figure of the use state, it shows the partial cross-section of the creation installed in the sealing groove. The overall shape of this creation is exquisite and unique, with novel and unique visual effects and creativity.
