摘要： A fluid pressure regulator includes a regulator housing having an inlet end and an outlet end; a flexible flow tube extending between the inlet end and the outlet end; a hollow piston located at a downstream location relative to a mid-portion of the flow tube in a direction of flow of fluid through the regulator housing; a first chamber above the piston and a second chamber below the piston; a passage establishing fluid communication between the outlet end and the first chamber; and at least one pinch arm pivotally mounted at one end within the regulator housing and movable in response to movement of the piston by an increase in fluid pressure in the first chamber so that an opposite end of the at least one pinch arm will pinch a portion of the flow tube and thereby restrict flow through the flow tube.

摘要： A pressure regulator includes a housing assembly defining a main fluid flow path from an inlet end to an outlet end. A tubular plunger body is supported within the housing assembly for linear movement toward and away from a valve seat in response to fluid pressure at said outlet end. An actuator sleeve is supported within the housing assembly and engaged with the tubular plunger body, and a pressure chamber defined in part by a shut-off diaphragm extends between the housing assembly and the actuator sleeve. A fluid port is arranged to supply pressurized fluid to the pressure chamber to thereby produce linear movement of the actuator sleeve and the tubular plunger body independent of the pressure at said outlet end, moving the tubular plunger body into engagement with the valve seat to shut off the flow path.

摘要： A weight component for an irrigation drop tube includes an elongated, hollow core sleeve, the core sleeve having a radially outwardly directed shoulder at one end connected to a radially outer skirt. A weight sleeve is supported at one end by the shoulder, inside the outer skirt, such that a chamber is created between the core sleeve and the weight sleeve. This chamber is at least partially filled with ballast material, and a cap closes the chamber at an opposite end of the weight sleeve.

摘要： A drop weight and connector assembly for use with an irrigation component mounted at a lower end of a flexible hose includes a tubular connector component having a first end adapted for insertion into the lower end of the flexible hose and a second end that is threaded and adapted for receiving a corresponding threaded end of the irrigation component. A drop weight component includes a relatively heavy tubular sleeve having one end that cooperates with the barbed end of the connector component to thereby clamp the lower end of the hose between the connector and drop weight components, the sleeve being sufficiently heavy to provide stability to the flexible hose and irrigation component.

摘要： A combination pressure regulator/drain check valve comprising a housing having an inlet, an outlet and a flowpath therebetween, the flowpath at least partially defined by a reciprocable plunger. One end of the plunger closest the inlet approaches a pressure regulator seat while the opposite end closest the outlet is engageable with a drain check valve seat. The plunger is normally biased toward the drain check seat.

摘要： A pressure regulator includes a housing assembly defining a fluid flow path from an inlet end to an outlet end; a plunger having a tubular plunger body supported within the housing assembly for linear movement toward and away from a valve seat in response to fluid pressure at the outlet end. A sleeve is supported within the housing assembly and is engageable with the tubular plunger body, and an actuator collar is supported externally of the housing assembly and operatively attached to the sleeve such that rotation of the actuator collar in one direction from an open position to a closed position produces linear movement of the tubular plunger body, independent of the pressure at the outlet end, into engagement with the valve seat to thereby shut off the flow path within the regulator.
