Abstract:
The invention relates to a connector head (12) comprising an interior space (40), a tank connector (13) which is in fluid communication with the interior space (40) and which can be fluidly connected to a valve apparatus (10) mounted on the tank (9) for filling or emptying the tank (9), a product port (14) in fluid communication with the interior space (40) and a discharge port (33) in fluid communication with the interior space (40). To allow a tank to be filled and emptied under improved hygienic conditions, it is proposed that the connector head (12) comprises a first valve (29), with which first valve (29) the product port (14) can be shut off from the interior space (40), a second valve (34), with which second valve (34) the discharge port (33) can be shut off from the interior space (40), and a cleaning device (38) adapted and arranged to clean the interior space (40) and the tank connector (13). The invention also relates to a valve block.
Abstract:
A valve assembly (10) for large scale irrigation including a valve body (20) and a valve head (40). The valve head is adapted to reciprocally travel along a longitudinal axis, supported by a longitudinally aligned shaft (60) inside the valve body. The valve head includes a wall (41) terminating in a peripheral sealing contact surface (42), the wall extending inwardly from the peripheral contacting surface.
Abstract:
One embodiment is related to a valve apparatus to be mounted on a fuel tank. The valve apparatus including: a housing including a ventilation chamber on a bottom face of which a first opening and a second opening are provided, and a valve chamber communicating with the first opening and disposed below the ventilation chamber, and a float valve disposed in the valve chamber. The housing includes a canister-connecting pipe communicating with the second opening. A standing wall is disposed on the bottom face of the ventilation chamber between a peripheral edge portion of the first opening and a peripheral edge portion of the second opening. And, an overhang wall portion extends from a side face of the standing wall toward the first opening, as viewed from above.
Abstract:
A connector to connect a fluid path to a fuel tank includes a main portion made of a synthetic resin through which a gas produced from fuel hardly passes, and a shell formed outside the main portion and made of a synthetic resin through which the gas passes easier than the main portion and which can be melt-bonded to the outer surface of a fuel tank. The main portion includes a flange part in the outer periphery. The shell has a wall section for a melt-bonding portion which extends around from the top surface side of the flange part and covers the bottom side of the flange part. The undersurface of the flange part is provided with an inclination having the peripheral edge side of the flange part upside thereof.
Abstract:
The invention is directed to a valve system comprising of moving parts therein. The valve system is designed to be resistant to the effects of low temperatures which otherwise tend to compromise the correct operation of the moving parts of the valve system. The inventor has cleverly got around this problem by designing a valve in which the moving parts thereof are positioned inside the contents of a tank. The contents of the tank ensure that the moving parts are less vulnerable to fluctuations in temperature outside the tank. Consequently, the invention provides reliable valve operation during freezing weather.
Abstract:
An apparatus for inoculating a sample to or withdrawing a sample from a vessel or conduit includes a body with an internal sample cavity, a valve operating rod movable to open and close an orifice to the sample cavity and a coupler to attach the body to a port of the vessel or conduit. A portion of the sample cavity is formed by an endcap which includes the orifice. The sample cavity is thermally and/or electrically insulated from the vessel or conduit. This insulation can arise from an empty or filled space between an inner wall and outer wall of the valve. Otherwise, insulating material can be used in forming the valve. The valve can be mountable on the vessel or conduit such that a positive drain angle is maintained regardless of whether the ferrule to the vessel or conduit is inclined upwardly, downwardly or is horizontal.
Abstract:
A valve for sampling a process from a tank or conduit includes an internal cavity in communication with at least one inlet and an outlet. A valve actuating rod includes a sealing tip attached to one end thereof. The valve actuating rod is movable to open and close the inlet to the internal cavity. Furthermore, a seal is provided to isolate the valve actuating rod and the outside environment from the process. The seal is formed on the process side of the bottom wall of the internal cavity in order to ensure that the process material, cleaning material, steam, etc. drains completely out of the internal cavity of the valve.
Abstract:
An assembly for swinging an external handle of a tank dome valve on a tank dome about a generally horizontal axis has a gearbox and an air motor. In a preferred embodiment, a housing is cooperatively formed by the gearbox casing and the motor cover. The gearbox contains a worm that meshes with a gear that turns within the casing. The air motor turns the worm, thereby turning the gear. An adapter that is external to the casing has a spline that passes through an aperture in the casing to mesh with an internal spline of the gear. The adapter is shaped for engagement with the handle of the tank dome valve. The housing and adapter are arranged such that, when the adapter is in engagement with the valve handle and the motor is operated to turn the gear via the worm, the far end of the motor cover is forced to bear against the tank dome and consequently force the adapter to swing the handle.
Abstract:
A valve assembly for a tank having an opening. The valve assembly includes a body assembly mounted to the tank opening. The body assembly has a valve seat and a valve throughbore. A valve disk coacts with the valve seat for opening and closing the valve throughbore. A locking lug is attached to the valve disk. The locking lug has a locking portion for receiving a safety lock pin mounted in the body assembly. The safety lock pin has a locked position and an unlocked position. The safety lock pin is received in the locking portion of the locking lug to lock the valve disk in the locked position, and the safety lock pin is withdrawn from the locking portion in the unlocked position. A valve operator is in releasable contact with the valve disk. The valve operator forces the valve disk away from the valve seat to open the valve throughbore. The body assembly includes a first member and a second member and the lock pin is mounted in the first member. A shear plane is formed between the first and second members such that the second member may be sheared from the first member at the shear plane without affecting the integrity of the lock pin in the locked position.
Abstract:
A valve has a valve member and an actuating member supported on the valve member by a mounting pin for actuating movement, wherein the pin has an axis extending between opposite ends thereof and the actuating member is connected to the pin intermediate its ends. The pin is supported on the valve member by a resilient coupling assembly including a support ring engaging the opposite ends of the pin and floating on a wave spring seated on a second support ring which is screwed to the valve member so that forces applied to the pin perpendicular to its axis will translate the pin against the spring rather than bend the pin. The second support ring is welded to a retaining ring and cooperates therewith to retain the spring and the first support ring in an integral cartridge module which can be mounted as a unit on the valve member.
