摘要： In one embodiment, a constant-flow valve assembly is provided that comprises a first fluid passageway carrying fluid at a first fluid pressure, a piston chamber, and a second fluid passageway connected to the chamber and carrying fluid at the second fluid pressure. A third fluid passageway is configured to carry fluid at a third fluid pressure. An adjustable valve member is provided between the chamber and the third passageway to provide constant fluid flow to the third passageway. An adjustable restrictor assembly is positioned between the first and second fluid passageways. An inlet portion of the restrictor assembly receives fluid at the first fluid pressure and directs the fluid to a restrictor. An outlet portion receives fluid from the restrictor and directs the fluid to the second fluid passageway at the second fluid pressure. The restrictor is movable to adjust the position of entry and exit portions relative to the inlet and outlet portions to adjust a fluid flow rate through fluid pathway to the second fluid passageway, thereby adjusting the flow rate through the valve assembly.

摘要： By using fabrication procedures, and not using any casting procedures, a pipe sleeve assembly per se, or with additional components, is made for installation on a pipeline. When this pipe sleeve assembly is fully tightened about a plastic pipe, there is acceptable limited radial deflection of cross-sectional portions of the plastic pipe, being sealed by a surrounding gasket held in place by assembled fabricated parts and bolt and nut fasteners of this pipe sleeve assembly. On opposite sides of each separating gap of the pipe sleeve, side bar and lug units are welded to the pipe sleeve. Between opposite lugs, independently removable bolt and nut fasteners are secured. In one embodiment, opposite lugs both have holes, which are aligned to receive and to hold portions of a bolt. In another embodiment, one of the opposite lugs has a hole, and the other opposite lug has spaced portions thereof, each having an overlapping lip portion, which receive a drop in bolt portion located near the head of the bolt. The bolt is then moved, so the bolt head is located under the overhanging lip portions, and another bolt portion is arranged within the hole of the opposite lug. Upon tightening of the respective nuts, the respective independently removable bolt and nut fasteners are secured in place holding the sleeve sections together. These embodiments are fabricated from stainless steel, mild steel and bronze. While fasteners are kept clear, other fabricated parts have surfaces treated by: impacting blasting particles, chemicals and/or coatings.
