IMPROVED NON-PRESSURIZED FLUID LEVEL SHUTOFF FOR FUEL TANK

A non-pressurized fluid level shutoff system for a fuel tank includes a fuel receiver having a flow control valve that opens in a direction opposite a direction of fuel flow, and that cannot be manually overridden. A fuel sensor funnels fuel through a fuel jet outlet orifice to form a stream of fuel across a cutout section, and a supplemental peripheral port connected between an outlet orifice mixing chamber and the interior of the tank is oriented perpendicular to the stream of fuel across the cutout section, to interfere with the stream of fuel when the sensor is submerged in fuel in the tank, to further reduce any residual fluid flow signal when the sensor is fully submerged, allowing the flow control valve in the receiver to close completely.

FLOW CONTROL VALVE ASSEMBLY

A fluid flow control valve (10) has a piston (43) in a first chamber (45), urged by a spring (46) to close fluid passages (36) interconnecting the first chamber (45) to a second chamber (51). A fluid level sensor (20) in a container (100) allows fluid to be bled from a downstream side of the first chamber (45), via a bleed passage (45), to enable the piston (43) to move to open the fluid passages (36). When the fluid sensor (20) detects that the fluid level (101 ) in the container (100) has reached a preset level, the fluid level sensor (20) shuts off flow through the bleed passage (45) and the equalization of the fluid pressure on both sides of the piston (43) in the first chamber (45) enables the spring (46) to move the piston (43) to close the fluid passages (36), shutting off fluid flow through the valve (40).

Pressure and oil sensor of owe body for use pump control cirxccircuit

본 발명의 일체형 압력 및 유량센서를 이용한 펌프 제어회로는 압력센서 및 유량센서를 일체형으로 형성하고, 일체형으로 된 압력 및 유량센서가 각기 검출하는 압력 및 검출신호 및 유량 검출신호를 이용하여 유체의 흐름을 보다 제어하는 것이다. The pump control circuit using the integrated pressure and flow sensor of the present invention is formed by integrally forming a pressure sensor and a flow sensor, and the flow of the fluid using the pressure and the detection signal and the flow rate detection signal respectively detected by the integrated pressure and flow sensor To control more. 종래에는 별개로 구성된 압력센서 및 유량센서를 사용하여 작업시간이 많이 소요되고, 압력센서 및 유량센서중에서 어느 하나만을 사용하여 유체의 흐름을 판단하여 펌프의 구동을 제어하였으므로 유체의 흐름을 정확히 제어하지 못하였으며, 압력센서 및 유량센서를 모두 사용하는 것도 압력센서 및 유량센서의 검출신호를 모두 고려하여 펌프의 구동을 제어하지 않았고, 단순제어를 하여 유체의 흐름을 정확히 제어하지 못하였다. Conventionally, it takes a lot of work time by using a pressure sensor and a flow sensor that are configured separately, and the pump is controlled by judging the flow of fluid using only one of the pressure sensor and the flow sensor. In addition, the use of both the pressure sensor and the flow sensor did not control the driving of the pump in consideration of the detection signals of the pressure sensor and the flow sensor, and did not accurately control the flow of the fluid by simple control. 본 발명은 압력센서 및 유량센서를 일체로 구성하고, 압력 센서의 검출압력이 정상압력 이하이거나 유량센서가 검출한 유체의 흐름이 정상일 경우에 펌프를 구동시키게 하고, 펌프의 구동시에는 유체의 압력이 높을 경우에 펌프를 정지시키게 하는 것으로 일체로 구성된 압력센서 및 유량센서의 검출신호를 복합적으로 사용하여 펌프의 구동을 제어함으로써 펌프의 구동에 따라 공급되는 유체의 흐름 및 압력을 정밀하게 제어할수 있다. According to the present invention, the pressure sensor and the flow sensor are integrally formed, and the pump is driven when the detected pressure of the pressure sensor is equal to or less than the normal pressure or the flow of the fluid detected by the flow sensor is normal. In this case, the pump is stopped to control the driving of the pump by using a combination of the detection signals of the pressure sensor and the flow sensor that are integrally formed, thereby precisely controlling the flow and pressure of the fluid supplied according ...

Method of automatic control of electrode boiler operation conditions

1445241 Vapour generators PLASCON AG 29 Jan 1974 [9 March 1973] 4166/74 Heading F4A [Also in Division G3] The supply and removal of water from a vaporization vessel 1 having heating electrodes 2 is controlled by a device for comparing the measured current flow with a preset desired flow and a device for opening and closing inlet and outlet valves 3a, 4a, depending on the result of the comparison. With the switching positions as shown in Fig. 1, a control voltage U ST is applied to the valve 3a to feed water into the vessel 1. As the water rises up the electrodes 2, the current in lines 2a, 2b increases until it reaches a maximum preset by a rheostat 5e at which point a threshold switch 6 is actuated to supply the control voltage to a timer 9. The supply of water to the vessel is thus interrupted together with the simultaneous actuation of a relay 10 to connect liner 8b with line 4b. The current now drops due to the water vaporization and the time taken for it to reach a predetermined minimum value is measured. The measured time is longer than the desired time since the latter has been calculated for water having a conductance higher than that found in the local water supply. Thus the relay 10 will return contact 10c to its initial position before the threshold switch 6 can return contact 6c to its initial position. Thus when the minimum value for the current is reached the switch 6 reactivates the valve 3a to feed water to the vessel 1. As the number of these cycles increases, the concentration of salt in the water rises so that eventually the actual dropping time is shorter than the predetermined time. At this stage the switch 6 will return to its initial position before the return of the relay 10 so that the control voltage is applied to the valve 4a. Water is thus drained from the vessel 1 until the expiry of the time set on the timer 9 after which the valve 4a is closed and the valve 3a opened. The replenishment cycle may now begin again. In a second embodiment ...
