Abstract: A valve assembly structured to reduce the volume of water along a path of fluid flow of a water supply line, including a valve body having a stabilizing chamber, a receiving chamber, and a valve member disposed therein. The valve member is disposable between an open orientation and a closed orientation relative to fluid flow between the stabilizing and receiving chambers. A biasing structure is disposed to normally bias said valve member into the closed orientation and is configured to exert a predetermined biasing force on said valve member. A transfer passage is disposed in fluid communication with and between the stabilizing and receiving chambers and is configured to define and direct a decreased volume of fluid flow, at an increased water pressure, on said valve member, wherein the increased water pressure is greater than the predetermined biasing force and sufficient to dispose the valve member in the open orientation.

Abstract: A kelly valve for placement in a tubular drillstring has an inner cage, which holds a valve ball, lower valve ball seat and other valve components. A valve stem connected to the valve ball extends through a valve stem sleeve, positioned in an opening in the wall of the main body of the kelly valve. A thrust bearing of a low friction material, preferably of polyether ether ketone (PEEK), is positioned between the valve stem and the valve stem sleeve. A port in the valve ball seat permits pressure below the kelly valve to bypass a seal and act on the inside of the valve ball. A circumferential notch in the valve ball seat accommodates a circular spring, and prevents complete compression of the spring when the valve ball seat contacts an interior shoulder in the inner cage.

The closing body is guided axially and/or radially by at least one guide ball. The at least one guide ball is arranged between the closing body and a lateral delimitation of the fluid chamber. A fluid passage is formed in the radial direction of the valve body.

Abstract: A blast gate has a branch dust connector, a main duct connector, and a gate. The branch duct connector has a first tubular portion. The main duct connector is stably connected with the branch duct connector and has a second tubular portion, an inside surface, and a leak-proof protrusion. The inside surface faces the branch duct connector, and the leak-proof protrusion protrudes from the inside surface of the main duct connector and has a protrusion opening communicating with an interior of the second tubular portion.
