Embodiment Construction

[0027] It should be understood that the term "plurality" as used herein means two or more. The terms "outer side" and "inner side" refer to the relative positions of various features with respect to a common axis or plane. The term "coupled" means directly or indirectly connected to or engaged with, eg, an intermediate member, and does not require the engagement to be fixed or permanent, although the engagement may be (or integral). The terms "first", "second", etc. as used herein do not imply an assignment to a particular component so designated, but merely refer to these components in the numerical order mentioned, which means that the specified An element being "first" may be followed by such an element being "second," depending on the order in which the elements are mentioned. For example, depending on the order in which the "first" diameter and the "second" diameter are referred to, the "first" diameter may hereinafter be referred to as the "second" diameter. It should ...

Abstract

A block forged valve body includes a fully encapsulated seat ring. The valve body includes a through hole and a chamber having a shelf portion that overlies an annular shoulder that encapsulates the valve seat. Methods for the manufacturing and use thereof are also provided.

Description

[0001] This application claims the benefit of U.S. Provisional Application No. 62 / 694,247, filed July 5, 2018, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The present disclosure relates generally to valve bodies, and in particular to methods of making a unitarily forged valve body having a fully encapsulated seat ring, and to a unitarily forged valve body having a fully encapsulated seat ring and How to use it. Background technique [0003] A gate valve generally includes a valve body having a flow passage and a gate that slides laterally to open or close the flow passage. Typically, a pair of valve seats are positioned in the flow passage to interface with the gate as the gate moves between open and closed positions. In some embodiments, the valve seat is not fully encapsulated around its circumferential rim, which results in the valve seat being prone to deflection or deformation. Deformation of the valve seat may result i...
