Valve assembly and system

摘要

A novel valve assembly is provided. In one embodiment, the valve assembly includes a seat plate that includes a fluid conduit and an impact bushing that is coupled to the seat plate at a position adjacent to the fluid conduit. The valve assembly also includes a sealing assembly that is configured to form a seal with the impact bushing and to control flow of a fluid through the fluid conduit via relative displacement of the sealing assembly from the impact bushing. Systems and methods related to such a valve assembly are also disclosed. Data supplied from the esp@cenet database-Worldwide.

1. A valve assembly, comprising:
a seat plate having a first fluid conduit; a guard plate having a second fluid conduit; a first impact bushing formed of plastic having an outer wall, a central guide, and one or more arms supporting the central guide, wherein the first impact bushing is coupled to the seat plate proximate the fluid conduit, and the central guide is configured as a linear bearing; a sealing assembly configured to form a seal with the first impact bushing and to control fluid flow through the first fluid conduit via relative displacement of the sealing assembly from the first impact bushing, the sealing assembly comprising:
a poppet having a guide member protruding from a first surface of the poppet; anda biasing member configured to bias the poppet; wherein the central guide cooperates with the guide member to maintain alignment of the poppet during operation of the valve assembly, and wherein a distal axial end of the guide member of the poppet is disposed inside the central guide of the first impact bushing between opposite axial ends of the outer wall in both an open position and a closed position of the poppet; wherein the guard plate is coupled to the seat plate such that the sealing assembly is disposed between the guard plate and the seat plate, and the guard plate includes a shoulder arranged within the second fluid conduit; and a second impact bushing formed of plastic is coupled to the guard plate in contact with the shoulder, wherein the second impact bushing is configured to contact a second surface of the poppet opposite the first surface of the poppet during operation of the valve assembly.
