摘要： A negative pressure pipeline opening-and-closing device includes a blocking member and a buoyant member. The buoyant member comprises two floats and a connection rod connected to the two floats. The liquid reservoir is provided with a guide therein, and the guide confines the two floats, the blocking member and the liquid outlet port in the same vertical line. A limiting member is arranged between the two floats and is fixed to an inner wall of the liquid reservoir. A maximum distance between the limiting member and a top wall of a lower float of the two floats is smaller than a maximum distance between a top wall of an upper float of the two floats and a top wall of the liquid reservoir. The negative pressure pipeline opening-and-closing device can replace an existing electrically controlled valve. Therefore, the cost is reduced, the maintenance is convenient and service life is prolonged.

摘要： Chiller operating efficiency is optimized by controlling the system to maintain the condenser liquid refrigerant level at a value which will minimize or prevent gas bypass to the evaporator (110). This is accomplished by sensing the level of liquid refrigerant (170) in the condenser (100) and incorporating fuzzy logic to properly position a multi-position valve (140) which can variably restrict the flow of this liquid into the evaporator (110), according to this sensed parameter (170). The fuzzy logic utilizes as inputs both the level error from a set point level (501) and the rate of change of the sensed level (504). Each of these inputs is combined by fuzzy logic techniques to provide the required output signal to control the opening and closing of the valve.

摘要： The invention relates to a liquid dispensing reservoir (1) with an outlet (3) opening provided in the (bottom) wall of the same. The outlet (3) opening merges into an auxiliary reservoir (4) located under the (main) reservoir (1), that is provided with an auxiliary outlet opening (3) and accommodates a float type valve body (6) that cooperates with the outlet opening (3) of the main reservoir (1). The sizes of the two outlet (3,5) opening are such that with the main reservoir (1) at least filled to a minimum level (III) and the auxiliary outlet (5) opening in the opened position, a substantially constant liquid level will be set within the auxiliary reservoir (4) due to the valve body (6) causing a regulated flow of liquid to discharge from the main reservoir (1).

摘要： A simple flow control device is provided in a condensate drain pipe (11) to prevent the flow of refrigerant vapor theretrough and to regulate the flow of liquid refrigerant as a function of the level of accumulated liquid refrigerant in the drain pipe (11). The only moving part is a float device (28) that rides up on a cylindrical valve body (27) in response to the level of liquid refrigerant to thereby expose slots in the valve body (27) which allow for the flow of liquid refrigerant to the refrigerant return line (22) to the cooler.

摘要： Apparatus suitable for processing semiconductor slices, the apparatus comprises a tank (1) for receiving a jig carrying semiconductor slices, a first supply line (2) for supplying a processing liquid to the tank (1), a supply valve (3) for controlling liquid supply through the first supply line (2), the supply valve (3) being operable in response to changes in fluid pressure at a control port (4) of the supply valve (3) and a second supply line (5) for supplying fluid to the control port (4) to control operation of the supply valve (3). The second supply line (5) communicates with an inlet (8) of the tank (1) via a control valve (7) which is operable in response to changes within the tank to control the fluid pressure at the control port (4) and so control operation of the supply valve (3). In the arrangement shown in Figure 1, a valve member (7a) of the valve (7) is carried by a platform (9) pivotally mounted within the tank (1). The weight of a jig carrying semiconductor slices acting on the platform (9) causes the platform (9) to tilt to close the control valve (7) thereby increasing the fluid pressure at the control port (4), causing the supply valve to open and so supply liquid to the tank via the inlet (1ʹ).
