摘要： A valve flush apparatus includes a rigid base designed to removably attach to a body of an irrigation valve. A stem extends outwardly from the base and away from the body of the irrigation valve and may be centrally located on the base. The stem and an aperture in the base may define a water passageway through which water may flow through the body of the irrigation valve and through the valve flush apparatus. A hose may also be included which removably attaches to the stem so as to extend the water passageway of the valve flush apparatus. A method includes flushing a clogged irrigation valve through use of the valve flush apparatus.

摘要： Lightning-dissipative A/C assemblies are provided, as are valve frames utilized within lightning-dissipative A/C assemblies. In embodiments, the lightning-dissipative A/C assembly includes a base dielectric component having a mount interface, a strike-susceptible metallic component coupled to the base dielectric component, and mounting hardware configured to engage the mount interface to attach the base dielectric component to an A/C. An electrically-conductive coating overlies or is formed over at least a portion of the base dielectric component to complete a lightning strike dissipation path. The lightning strike dissipation path extends from the strike-susceptible metallic component, through the electrically-conductive coating, through the mounting hardware, and to an A/C electrical ground plane when the lightning-dissipative A/C assembly is installed on the A/C. In one implementation, the base dielectric component assumes the form of a valve frame, while the strike-susceptible metallic component assumes the form of a valve door movably mounted to the valve frame.

摘要： The invention is an improved tool for pulling a valve seat from a valve in a fluid end. The invention replaces the standard threaded nut and stem commonly used in such tools with a split nut comprising a plurality of removeably engageable split nut segments placed within a base and a stem configured to be used with the plurality of removeably engageable split nut segments. In the preferred embodiment, each split nut segment possesses a center-facing surface relative to the longitudinal axis of the invention comprising a set of horizontal v-grooves suitable to be disposed against complementary v-grooves of the stem. The base permits the plurality of split nut segments to be placed in an engaged position permitting the v-grooves of the split nut segments to removeably engage the v-grooves of the stem securely or to be placed in a disengaged position. The base containing the split nut segments is durable enough to be used in oil field work but lightweight enough to be used by individual or groups of workers safely.

摘要： A leak proof, completely sealed solenoid valve, comprising a housing 14 having a fluid flow path controlled via an electrically operated mechanism to control a flow; the mechanism comprises metallic coil 20 coiled around a bobbin 16 supported by a magnetic bracket 24 with terminal pins 18 connected to the bobbin 16 for receiving electrical input to facilitate an energized and de-energized state to control the movement of a poppet 34 shaft that obstructs the flow; wherein, the bobbin 16 comprises micro-melting fins, thereby housing over molding creates strong bond between two materials; a permanent weld is created between the bobbin 16 and the housing 14 to prevent internal leakage; and the completely sealed solenoid valve limits emissions and evaporations of the volatile fuel components into and from the valve, and contribute to reliability and robustness of the product by completely sealing the nozzle and housing using laser welding.

摘要： A valve plug assembly includes a plug base, a first end of the base arranged for attachment to a valve stem, a second end of the plug base including a bore having a first portion and a second portion. The second portion of the bore is a conical terminus forming a first seat. A spacer has a through bore, a first end, and a second end, and is sized for insertion in the bore of the plug base and has a conical shape to engage the first seat, and the spacer also forms a second seat. A plug tip has a through bore and a conical end engaging the second seat and is arranged to engage the valve seat, and a cap screw extends through the plug tip and the spacer to mechanically secure the plug tip to the plug base.

摘要： A solenoid device includes a yoke, a core, a shaft, a bobbin, a coil, a plunger, a lid, and a housing. A housing body part of the housing has a first opening; a cylindrical first inner wall part having a first step part extending toward the outer side in the radial direction; and a cylindrical second inner wall part having a second step part extending toward the outer side in the radial direction. A first cylindrical part has a first flange part. The outer diameter of the first flange part is larger than the inner diameter of the first inner wall part and smaller than the inner diameter of the second inner wall part. A circumferential end part of the first flange part contacts the second step part. The lid is non-magnetic, and a circumferential edge part is held between the first step part and the first flange part.
