Abstract

A gate valve sleeve including a reinforced elastomeric valve sleeve member with an integrally molded reinforcing member disposed therein. In one embodiment, the reinforcing member comprises a pair of parallel spaced ring elements connected by a plurality of spacers. In another embodiment, the reinforcing member comprises first and second ring member abutted to form a T-shape. In a further embodiment, the reinforcing member comprises a ring and a plurality of axially oriented spacer members. In yet a further embodiment, the reinforcing member comprises a pair of ring elements connected by a plurality of pins. The pins are fixed to one of the ring elements and are slidably engageable with the other ring element. In an alternate embodiment, an auxiliary ring member is located within an interior opening of the reinforcing member.

Description

[0001] Horizontal references for related applications [0002] This application requires the rights and interests of the U.S. Provisional Application No. 61 / 383,428 filed on September 16, 2010 under the provisions of 35U.SC§119(e) named "IMPROVED SLEEVE SEAL FOR GATE VALVES". The entire content is incorporated herein by reference, and this application claims the priority of this US provisional application. Technical field [0003] The present invention relates to a sleeve seal for a gate valve, and more particularly to a gate valve sleeve including a reinforced elastomer valve sleeve provided with an integrally molded reinforcement member inside. Background technique [0004] When linear flow of fluid with minimal restriction is desired, gate valves are used in fluid manipulation applications. When the valve is in the closed position, the gate or valve plate engages a pair of opposed seals to cut off the linear flow. When the gate is raised so that the valve is in the open positio...
