摘要： Each gripper washer 22 is disposed between a gasket retaining ring 18 and an end connector 14. The gripper washers 22 can be any size and dimension, and made from any material, including but not limited to plastic, polyvinyl chloride, or metal. The gripper washers 22 are a washer-like structure, typically a metallic structure that comprises an interior diameter, a concentric inner periphery and an exterior periphery 24. Each gripper washer 22 is disposed between a gasket retaining ring 18 and an end connector 14, such that the exterior periphery 24 of the gripper washer 22 is in contact with, or in close proximity to, the shoulder 20 of the gasket retaining ring 18.

摘要： An improved arcuate sweep elbow pipe connector section having an increased flow capacity and is a replacement for conventional ninety degree elbows as part of the piping system used to deliver water from a source to a fire sprinkler head. The arcuate sweep elbow pipe connector section is integrally formed at one end with a first connecting section and integrally formed at a section end with a second connection section. The connecting sections are positioned ninety degrees relative to each other and the arcuate sweep elbow pipe connector section optimizes water flow through both connecting sections.

摘要： A valve operator assembly may include a housing, a yoke, and one or more stoppers. The housing is mountable on a valve, and includes a body having a sidewall including a shaft bore, to receive a shaft rotatable within the housing, and a cover having a top member mountable on a top portion of the body and a side portion extending downwards adjacent to and partially overlapping the sidewall. The yoke is operably coupled by a yoke nut to the shaft to impart rotation to a valve stem of the valve when the shaft is rotated. The one or more stoppers are disposed within the housing to restrict the linear motion of the yoke nut.
