  • Patent number: 10794593
    Abstract: A vaporization pipe for a kerosene lamp has an oil tube, a thermally conductive tube, and a first passage. The oil tube is made of steel and has a vaporization jet on a top of the oil tube. The thermally conductive tube is mounted in the oil tube and forms a first channel. The first passage is disposed between the oil tube and the thermally conductive tube. The steel oil tube can prevent the vaporization pipe from being softened and bent during the preheating of vaporization pipe or burning of the kerosene, and thus a useful lifetime of the vaporization pipe is prolonged. The thermally conductive tube is made of high-thermal-conductivity material for keeping the vaporization pipe with adequate thermal conductivity and improving a burning rate of kerosene. The first passage allows the kerosene to flow upward, preventing the kerosene from being vaporized incompletely because the kerosene is over pressurized.

  • Patent number: 6637452
    Abstract: The seal assembly is disclosed for use with a valve having a trim cage with an inner surface extending along in axis and a plug sized to fit inside the trim cage inner surface, wherein the plug is adapted to move along the axis thereof. A seal ring is attached to an upstream portion of the cage to effectuate a seal with the plug. The plug is equipped with a wiper seal that cleans or otherwise removes debris from the seating surface of the seal ring, an interior surface of the seal ring and an interior surface of the cage during both the opening and the closing of the valve. Thus, the valve is self-cleaning. Further, the wiper seal delays throttling action through the valve until the plug has moved a substantial distance away from the seating surface of the seal ring which reduces high pressure abrasive flow against the seating surface of the seal ring to reduce wear on the trim set.

  • Patent number: 6293298
    Abstract: A water softener valve for controlling water flow to and from a water softener is disclosed that includes a cylindrical shaft extending from said inner surface of a piston chamber that fits into a pressure relief port when the piston is in the service position. The shaft clears the pressure relief port of any debris and closes the pressure relief port during the service cycle. The water softener valve also has a flow meter with at least two helically expanding vanes. A magnet on of the vanes trips a sensor as the turbine rotates, thereby providing means for calculating the flow of water through the valve. The valve also has a flow control button located at an inlet of the valve rather than at the drain, preventing the obstruction of the water flow by regeneration sediment of the tank at the drain. The valve also contains an internal piston port for permitting the free flow of water through the valve during a change in softener cycles.

  • Patent number: 6263901
    Abstract: An irrigation valve comprises a valve housing made from a valve body joined to a valve bonnet by a plurality of attachment screws. The valve body and valve bonnet have an alignment rib received in an alignment notch when the body and bonnet are joined together such that the holes that receive the attachment screws are automatically aligned with one another. The attachment screws have a smooth portion adjacent a threaded portion such that the smooth portion when visible signals to the user that the attachment screws are clear of the valve body but are still captured in the valve bonnet. The valve includes a solenoid that may be remotely actuated to open the valve. An L-shaped actuator arm is also operatively connected to the solenoid for manually opening the valve with the upper portion of the actuator arm being closer to the user than in previous valves and thus easier to grip and turn.

  • Patent number: 6199576
    Abstract: The invention is a bi-directional cleanout for pipelines such as sewer pipelines and a bi-directional cleanout with a built in backflow preventer. The backflow preventer is a check valve which allows fluid to flow in one direction, but not in the other direction. The bi-directional cleanout is a device which has a single access point at ground level, is located outside a house typically, and which directs a cleanout tool down one of two tool guide tubes. The guide tubes direct the cleanout tool into one of two tool guides which deflect the cleanout tool and cause it to enter the pipeline to be cleaned in a direction towards one or the other of the ends. The check valve is insertable into the pipe level unit in which the tool guides are located. While the pipeline is being cleaned out with the cleanout tool, the check valve can be removed and reinserted after the cleanout procedure is completed.

  • Patent number: 6182677
    Abstract: A cleanout fitting for air conditioner evaporator drains facilitates the mechanical cleanout and hydraulic flushing of the entire drain line from an air conditioner evaporator unit, or air handler. The present fitting essentially comprises an asymmetric T configuration, with a shutoff valve in one side of the crossmember of the T and a removable cap in the opposite end of the crossmember. The fitting is normally configured with the cap in place to block drainage therefrom, and with the valve open to permit flow from the evaporator pan through that crossmember side and out the stem of the T to an appropriate drain system. When the line becomes blocked and causes water in the evaporator pan to back up, the plug is removed, allowing a mechanical cleanout tool (snake, etc.) to be passed straight through the crossmember of the T and its open valve, to the evaporator pan.
