摘要:
The method of filling a fuel tank, especially bio-fireplace fuel tank, which allows fully automatic tank filling to a desired level and also, if necessary, its quick emptying due to, for example, a failure, is characterized by the fact that the fuel tank (4) designed for Filling is filled with fuel with the use of the electric pump (1) collecting fuel from the supplementary fuel container (6), whereby the electric pump (1) is electrically powered from the electrical socket (7) supplied with power from a controller (8), which, during the process of filling the fuel tank (4) with fuel and based on the signal from the fuel level sensor (9) activated when the desired level of filling the fuel tank (4) with fuel is achieved, cuts off power supply in the power supply socket (7) that supplies power to the pump (1); the electric pump (1 ) is connected to the fuel tank (4) detachable by the quick-release coupling (12), which is fixed to the fuel tank (4) and, by the fuel line (3), to the electric pump (1), and to which the hose (13) is fixed which is introduced into the bottom of the fuel tank (4), whereby the second fuel line (5) introduced into the fuel container (6) and connected to the electric pump (1) ends with the part of the quick- release coupler (14) which, if necessary, is connected to the fuel tank (4) intended for filling and fuel in it is pumped out. A characteristic of the assembly for filling a fuel tank, especially bio-fireplace fuel tank, is that it is composed of the electric pump (1), two fuel lines (3, 5) connected in sequence to the electric pump (1), of which the first fuel line is detachably fixed to the fuel tank (4) being filled by a quick-release coupler (12) connected with the hose (13) introduced into the bottom of the tank (4), and the second fuel line is introduced into the supplementary fuel container (6) and ends with the part of the quick-release coupling (14) which allows connection of the line, alternatively with the first line (3), to the fuel tank (4) intended for filling in order to empty the tank, and the socket-equipped (7) controller (8) which supplies power to the electric pump (1 ) connected to the socket (7), and the controller (8) has the function of cutting off power in the electrical socket (7) supplying power to the electric pump (1) and this function is activated by a signal from the fuel level sensor (9) built in the fuel tank (4) when the desired tank (4) filling level is achieved.

The invention is directed to a valve (10) for a gas tank (2), comprising a body (12) with a longitudinal axis to be mounted on an opening on a wall (43) of the gas tank (2), with a gas outlet port (14) and a gas refill port (20), a level gauge (18) with a pivoting float (46) for measuring the level of the liquid phase of the gas, an overfill protection device (22) with a pivoting float (26) for limiting refilling of the tank based on the level of the liquid phase of the gas. The pivoting float (46) of the level gauge pivots around a first axis (44) distant from the body (12), and the pivoting float of the overfill protection device is a distinct float (26) pivoting around a second axis (28) that is less distant from the body (12) than the first axis (44).

摘要:
An adaptor assembly (12) is provided for a pressurized gas container (14) having an internally threaded outlet port (38) for normally receiving a service valve. The adaptor assembly (12) includes a housing (70) having a lower externally threaded mounting portion (71) for mating with the internally threaded outlet port (38) and a check valve (74) operably associated with the housing (70). The check valve (74) has a valve shuttle (106) for movement between a normally closed position to prevent the transfer of liquid and/or gas between the container (14) and an exterior device and an open position to permit the transfer. The shuttle (106) is movable toward the open position only when a fitting (42) of the exterior device is operably connected to the check valve (74). A liquid level sending unit (16) with an overfill protective device (66) is connected to the adaptor assembly (12). A liquid level indicator (76) is connected to the housing (70). The indicator (76) is responsive to movement of the sending unit (16).
摘要:
A cryogenic storage tank comprises a partition that divides a cryogen space into a main storage space and an auxiliary space. A valve disposed inside the cryogen space is associated with a first fluid passage through the partition. The valve comprises a valve member that is actuatable by fluid forces within the cryogen space. A second fluid passage through the partition comprises a restricted flow area that is dimensioned to have a cross-sectional flow area that is smaller than that of a fill conduit such that there is a detectable increase in back-pressure when the main storage space is filled with liquefied gas. A preferred method comprises establishing a vapor-filled ullage space when the main storage space is being vented and re-filled with cryogenic fluid, by draining liquefied gas from the auxiliary space through the first fluid passage under the influence of a vapor pressure differential permitted by the partition. If the vapor pressure differential reverses during re-filling, the valve can close to preserve the vapor-filled ullage volume. Re-filling is stopped when an increase in back pressure is detected during re-filling.
摘要:
An improved apparatus and method for monitoring the levels of propane or other consumable liquid in remotely located storage tanks and coordinating delivery of liquid to those tanks, including an improved method of using the remote monitoring data to identify out-of-ordinary conditions at remote tanks, optimally schedule purchases or deliveries, improve safety, and more efficiently operate a propane dealership. More accurate and timely information concerning the status of customer tanks serves to improve operational efficiencies and increase safety. Data received from remote sensors can be collected and organized so that it is easily understood and utilized through the implementation of a user interface accessible via the Internet that allows the information to be presented in an efficient graphical and contextual fashion. Operational efficiencies can also be improved by calculating site-specific Degree-days and K-factors for each tank and by taking historical propane usage for each tank, weather conditions, and projected fuel usage into account.
