    • The present invention relates to valve plugs for reducing erosion of the valve plug head and/or seat. More specifically, this invention comprises a valve plug incorporating a choke transfer trim that reduces the time of exposure of the plug head and/or seat to high velocity and high pressure drop at the interface of the plug head and seat when the valve is in the closed position. The choke transfer trim transfers the flow control area of the valve away from the plug head/seat interface to a location downstream, thereby reducing erosion at the interface between the valve plug head and/or seat that is typically used for fluid throttling and shut off.
    • 本发明涉及用于减少阀塞头和/或座椅侵蚀的阀塞。 更具体地说,本发明包括一个带有扼流圈输送装饰件的阀塞,该阀塞减小了塞头头部和/或座椅暴露于插塞头和座的接口处的高速度和高压降的时间, 关闭位置。 扼流圈传送装置将阀的流量控制区域从插塞头/座接口传递到下游的位置,从而减少通常用于流体节流和关闭的阀塞头和/或座之间的界面处的侵蚀 。

    • In accordance with various aspects of the present invention, methods and apparatuses for designing and configuring dissimilar material retention, specifically a valve plug assembly, are disclosed. The methods and apparatuses enable the application of a wider range of materials in a valve plug assembly than previous valve plug assemblies, and also increase the operational temperature range of the valve plug assembly. In an exemplary embodiment, a valve plug assembly comprises a plug head, a collet surrounding the plug head, a plug base adjacent to the collet, and a retainer surrounding the tapered outside surface of the collet and the plug base, where the plug head extends past the collet and the retainer. The valve plug assembly is configured to create an interference fit of the various components.

    • A valve plug design is disclosed that uses a plug head band and a retaining ring to restrain a valve plug head to a valve plug stem. This invention is specifically directed to providing valve plugs where the plug head material is different and distinct from the plug stem material and where each material is selected to optimize its performance. Moreover, this invention is provided with a means for fixing and removing the plug head to and from the plug stem that can easily be worked in the field without special purpose manufacturing equipment, thereby making the maintenance, repair and replacement of plug head easier for users. This valve plug design subjects the plug head to reduced stresses thereby enhances the operating life of the valve and valve plug. This valve plug design provides a shock absorbing, compliance barrier around and/or under the plug head. This invention also provides a more uniform and broadened contact surface between the plug head and the plug stem, further reducing mechanical stresses to the plug head. This plug head invention requires less material and thus leads to reduced manufacturing costs and does not require welding to fasten the plug head to the plug stem, thereby permitting heat treatments as required without adverse impacts to the plug head to plug stem joint. Also, this invention is adapted to function in cooperation sensors embedded at the plug head—valve plug stem interface to permit the monitoring of alignment stresses on the valve plug head.
    • 公开了一种阀塞设计,其使用塞头带和保持环来将阀塞头限制到阀塞杆。 本发明具体涉及提供阀塞,其中塞头头材料与插塞杆材料不同且不同,并且其中选择每种材料以优化其性能。 此外,本发明提供了一种用于将插塞头固定和移出插头的装置,其可以在现场容易地在现场加工而不需要专门的制造设备,从而使用户的插头更容易维护,修理和更换 。 这种阀塞设计使塞头减小了应力,从而提高了阀和阀塞的使用寿命。 该阀塞设计在塞头周围和/或下方提供了减震,合规的屏障。 本发明还提供了塞头和插塞杆之间更均匀和更宽的接触表面,进一步降低了插塞头的机械应力。 这种塞头本发明需要更少的材料,从而导致制造成本降低,并且不需要焊接来将塞头固定到塞杆上,从而允许根据需要进行热处理,而不会对插头头部到插头杆接头产生不利影响。 而且,本发明适用于嵌入在插塞头阀插头杆接口中的配合传感器中的功能,以允许监测阀塞头上的对准应力。
