摘要:
An apparatus is supplied for a self adjusting regulator suited for an irrigation emitter. A curved flow channel is integrated into a concave dome shaped surface. A deformable member deforms to approach the surface to adjust the resistance to flow. The concave dome shaped surface may match a deformed shape of the membrane. Irregularities in the interface between the surface and the deformable member are configured to achieve a desired discharge under varying flow conditions. The deformable member may activate an inlet filter cleaner by pushing a ram and thereby unclogging the filter.

A diaphragm valve feature a valve body having a passage that opens to allow fluid to pass, and closes to prevent fluid from passing, through the valve body; and a bonnet assembly having a pressure ring to load/unload a diaphragm depending on a first spring constant to seal a peripheral portion thereof, and a compressor to close/open the passage of the valve body. A rotational connection fixes together the valve body and bonnet assembly with a second spring constant that is higher than and independent from the first spring constant, and includes the valve body having a rim with two shouldered pins on opposite sides. The bonnet assembly has a corresponding rim with two keyways on opposite sides thereof. Each keyway is recessed to receive and engage a respective shouldered pin when the bonnet assembly is rotated relative to the valve body.

A single chamber two-way servo-operated valve includes: a valve body presenting an inlet aperture, an outlet aperture, and an access; a cover to close the access of the valve body; a port dividing the valve body interior into an inlet section and an outlet section; a valving element including a disc for closing the port; and an actuating chamber at least partially defined by the cover. The disc and a flexible diaphragm are connected to the valving element. The disc of the valving element includes a rigid central core which is at least partially covered by a rubber layer adhering to the central core. The rubber layer extends from the edge of the disc to form the flexible diaphragm.

A diaphragm control valve has a universal diaphragm mounting location, the diaphragm control valve includes a bonnet, a valve body, a diaphragm, and a clamping washer. The bonnet includes a first clamping surface that transitions into a first annular retention surface formed by a skirt, and the valve body includes a second clamping surface that transitions into a second annular retention surface formed by an upturned annular lip.

A dual valve assembly includes two regulating valves. Each valve includes an outer housing comprised of a cap joined to a base. The housing is internally subdivided by a barrier wall into a head section and a base section, the latter being further subdivided by a modulating assembly into a fluid chamber and a spring chamber. An inlet and a 90° outlet in the cap communicate with the fluid chamber. Fluid at a variable pressure is admitted into the fluid chamber via the inlet, with the modulating assembly serving to maintain the fluid exiting the fluid chamber via the outlet at a substantially constant pressure. A smaller one of the valves has its base nested within the spring chamber of the other larger valve.

A gas pressure regulator comprises a main body having a first, gas inlet pipe and a second, gas outlet pipe, a calibrated gas passage through which gas flows from the first pipe to the second pipe, a shutter housed at least partially in the main body and mobile lengthwise along a first defined line to adjust the opening of the calibrated passage, a device for actuating the shutter and a regulator spring unit opposing the movement of the shutter.
摘要:
A pressure regulator having a base and a bonnet. The base includes a plurality of upstanding ridges, with an opening being defined between each of the ridges. The bonnet includes a peripheral rim having a plurality of engagement tabs located within each of the openings defined by the ridges of the base. The base is connected to the bonnet by folding the ridges over the peripheral rim of the bonnet. The ridges include side surfaces that mate with side edges of the engagement tabs to maintain the peripheral rim of the bonnet against the ridges as tension is applied to the peripheral rim that forces the peripheral rim away from the ridges. The bonnet also includes a plurality of interference tabs that engage an interior surface of the ridges before the ridges are folded over the peripheral rim of the bonnet to maintain the bonnet in proper position.
摘要:
A pressure regulator has a closing member (4) which controls a pressure-medium inlet (2) and on which is supported a valve spring (7) arranged in a spring can (8). The spring can (8) consists of a casing part (9) and of a lid (10). The valve spring (7) is supported with one end against this lid (10). Said lid is pushed into the casing part (9) until the necessary spring force is set exactly and is then connected to the casing surface (15) of the casing part (9) by means of radial indentations (12, 13).
摘要:
A modular pressure regulator/filter wherein the fuel filter is adapted to be attached to a fuel delivery system of an internal combustion engine and the housing thereof has a projecting wall on the filter housing adjacent to a female opening in the fuel filter housing. This projecting wall has at least one slot therein. A clip is provided and includes a disc portion with a central opening therein for selectively receiving a male outlet conduit from the pressure regulator. A clip projection, which is integral with and movably attached to the disc portion, is adapted to be selectively received into the slot in the projecting wall whereby the clip is held from moving away from the projecting wall. An annular projection on the pressure regulator housing is disposed between the disc portion and the clip projection when the clip projection is in the first position thereof for holding the pressure regulator housing in the clip. The clip therefore is used to selectively hold the pressure regulator housing and the filter housing together or allow them to be quickly and easily separated.
