  • Patent number: 8382993
    Abstract: A removable drain filter apparatus (20) with an housing (22) connectable with upstream and downstream drain pipes (40, 46) has a filtering chamber wider than the drain pipes and divided into an upstream portion (78) and a downstream portion (82) by a generally planer filter element (50). A hatch cover (32) carries a downwardly extending central core (76) with an O-ring seal (84), a filter securement member (86) for pressing the filter element (50) against an underlying support ledge (29) and a drain hole plug (88). The location of the O-ring (84) relative to the filter element (50) and the plug (88) being tapered enables the filter housing (22) to be drained of any water during removal of the hatch cover and before the watertight seal is broken to eliminate leakage of drain water out of the housing (22) when the hatch (31) is completely opened. The filter (50) bends out of the way of a plumber's auger (96).

    Abstract: The present invention prevents foreign matter from infiltrating into a control valve and enables reduction in the cost of the valve. A strainer is mounted on an attachment portion of a valve sleeve, and a valve spool is disposed in the sleeve so as to be free to slidably advance and retreat. The strainer includes engagement portions m1 contacting first contact sites ?1 and ?2 formed on the attachment portion and a contact portion contacting second contact sites ?3 and ?4 formed on the attachment portion. Since the strainer includes the engagement portions m1 in contact with the first contact sites ?1 and ?2 and the contact portion in contact with the second contact sites ?3 and ?4, the sleeve has sufficient sealing contact with the strainer 73 at the first and second contact sites ?1 to ?4.

  • Patent number: 7360611
    Abstract: A strainer system having two separate strainers positioned in parallel, where one strainer can be cleaned while still permitting normal flow through the other strainer. The system flow circuit is arranged so that a high pressure backwashing flow can be applied to one strainer while the other strainer is providing its normal straining function. The backwashed strainer is then isolated by valves so that its access flange can be removed and the particulate buildup within the valve plug cleaned out. The strainer is then returned to service following the replacement of the access flange. In this manner, it is possible to alternate between the two strainers so that continuous flow can be maintained to the hydraulic choke located downstream of the strainer system.

A primary valve seat inside the housing is engaged and disengaged by a seal on the underside of the diaphragm to open and close the valve by connecting and disconnecting its inlet and outlet passages. Pressurized water from a lower inlet chamber of the valve travels through a small metering orifice in the center of the diaphragm assembly to an upper pressure control chamber above a flexible membrane of the diaphragm assembly. A solenoid actuated pilot valve is operatively coupled to the upper pressure control chamber for venting pressurized water therefrom to permit the diaphragm assembly to move upwardly to open the valve. A filter screen is mounted to the underside of the diaphragm assembly to prevent debris from clogging the metering orifice, clogging the small passages of the pilot valve, or fouling the solenoid.

    Abstract: A combined valve and filter mechanism for use in chemical apparatus comprises a valve body having a valve seat connected thereto. A valve stem has a valve at one end thereof for engaging said valve seat and has a cylindrical filter element for telescoping within the valve seat. The mechanism permits filtration of the chemical in situ without a separate filtering mechanism while providing a valve which when open or closed permits the agitation of the chemical in the apparatus without interference with or from the valve and vice versa. In the fully open position, the entire contents of the apparatus can be withdrawn from the apparatus.

  • Patent number: 4566533
    Abstract: In the operation of cleaning the pipes of heat exchangers by means of sponge rubber balls which are entrained by the cooling water, a cylindrical housing is connected upstream of the heat exchanger, in which housing several chambers are formed by several dividing walls rotating about a vertical axis, and the chambers are subdivided by a horizontal sieve plate into an upper group of chambers for receiving the balls and into a lower group of chambers. In this arrangement, two opposite cooling water supply and removal connections are each provided in the region of the lower group of chambers, and two similar cooling water connections are provided in the region of the upper group of chambers which are connected to the heat exchanger pipes. In order to also allow a discontinuous cleaning operation, while stopping the balls and without interrupting the flow of cooling water, the present invention provides that the interior of the housing (2) is subdivided by three dividing walls (4,5,6) which are arranged at 120.

  • Patent number: 4518493
    Abstract: A noise attenuating filter for use in a fluid flow systems which includes a cylindrical body defining a plurality of arcuate open-ended passageways extending longitudinally therethrough, a corresponding plurality of small radial slots in one end thereof communicating with the passageways and a closing member biased outwardly from the slotted end of the cylindrical body so that during use, fluid flows about the closing member and into and through the arcuate passageways until such time as the fluid pressure on the closing member causes the closing member to cover the upstream end of the annular passageways whereupon the fluid is caused to travel into the passageways through the smaller radial slots thereby reducing the volume of flow through the system and attenuating the noise of the fluid flow while additionally preventing the passage of large particles through the system.

  • Patent number: 4328835
    Abstract: A valve for automatically dumping a load of solids entrained within a fluid transport medium in response to flow interruption is disclosed. The automatic dump valve is particularly well-suited for use in combination with a nodule transport riser in deep ocean mining operations. The automatic dump valve system is combined with a tubular conduit defining a longitudinally extending flow passage having a sidewall opening defining a dump port. The automatic dump valve assembly includes a movable dump port cover plate and a hydraulic actuator coupled to the cover plate. The hydraulic actuator is operably responsive to pressure changes within the flow passage relative to the pressure exerted by a surrounding body of water to open and close the dump port.

  • Patent number: 4209038
    Abstract: A fuel metering valve has a housing bore between an inlet and outlet which supportingly receives a movable valve element including an imperforate end plate and an annular, porous metal plate for regulating flow between the inlet and the outlet; the imperforate end plate includes an axial reference surface thereon to overlap the inlet and outlet to prevent flow therebetween. When the valve is initially opened to a low flow rate metering position, the reference surface is moved with respect to the inlet and outlet to interpose a predetermined planar extent of porous material for limited flow of fluid between the inlet and outlet with metering established by the flow area of interstices in the porous material rather than dimensional relationships between the reference surface and walls of the inlet and outlet.

  • Patent number: 4054507
    Abstract: Slurrying of water-wet wax particles in liquid hydrocarbon carrier is improved by introducing the water wet particles in a rotating perforated cylinder, e.g., screen, immersed in a flowing stream of liquid carrier above a settling chamber. The flow rates of the liquid carrier and the water-wet particles are controlled to give desired water separation and slurry concentrations for subsequent pipelining. The water falls to the bottom of the settling chamber for removal.
