摘要： An inflow protection device for preventing liquids and other contaminants from entering a water-carrying pipeline through an air valve connected to the pipeline. The inflow protection device includes an adaptor and an elongated vent pipe. The adaptor has a first end for coupling with an outlet of the air valve and second end. The vent pipe has a first end configured for directly or indirectly coupling with the second end of the adaptor and a second end extending out of and above a vault in which the air valve is installed. The vent pipe is of a length sufficient to position its second end above a flood plain level so that the second end allows air to be exhausted from and admitted into the air valve even when the vault in which the air valve is located becomes flooded.

摘要： A valve-closing pressure chamber and a valve-opening pressure chamber are arranged on both sides of a main diaphragm inside an outlet shutoff valve. An upper supply/discharge tube and a lower supply/discharge tube are connected to a housing forming the outlet shutoff valve. The upper and lower supply/discharge tube supply and discharge air to and from the valve-closing pressure chamber and the valve-opening pressure chamber, respectively. An opening end, which is on the pressure chamber side, of each supply/discharge tube is obliquely cut relative to the direction of axis of the supply/discharge tube, which increases the opening area of the opening end. This prevents water present in the pressure chamber from adhering to the opening end of each supply/discharge tube and prevents the adhered water from freezing. This in turn prevents the opening end of the supply/discharge tube from being closed or the opening area from being reduced. As a result, operation performance of the outlet shutoff valve is enhanced.
摘要翻译： 阀门关闭压力室和开阀压力室布置在出口截止阀内的主隔膜的两侧。 上供排管和下供排管连接到形成出口截止阀的壳体上。 上，下供排管分别向阀关闭压力室和开阀压力室供给和排出空气。 每个供给排放管的压力室侧的开口端相对于供给/排出管的轴线的方向倾斜切割，这增加了开口端的开口面积。 这样可防止存在于压力室中的水分粘附到每个供给/排出管的开口端，并防止粘附的水冻结。 这又防止供给/排出管的开口端被关闭或开口面积减小。 结果，提高了出口截止阀的操作性能。

摘要： A ventilation arrangement for the head space of the fuel tank of a vehicle comprises a switchable main valve intended for adjusting an arbitrary pressure in the head space of the tank. By way of the opening position of the main valve, a connection between a connection (5) intended for connection to the head space and a connection (6) intended for connection to the surrounding atmosphere is established, wherein the main valve is assigned a pilot valve, which opens during a first path element of a switching movement, wherein the main valve only opens following this first path element. Because of the small cross section of the pilot valve and the pressure relief that materialized through its opening, the switching power can be reduced and a smaller size drive can be employed.

摘要： A valve assembly (1) for measuring differential pressures in a fluid system where the valve assembly includes a differential pressure sensor (12) for registration of differential pressures, a first cavity (22) with a calibrating cone (10) displaceable between measuring and a zero point calibration/flushing position. The valve assembly (1) includes a valve body (7) with two connections (13, 14) and a second cavity (15) arranged with a safety valve cone (8) which protects the differential pressure sensor (12). The safety valve cone (8), by differential pressures higher than a dimensioned value, is moved in a direction towards the low pressure side and, as a result, a passage between high and low pressure side is opened, from one connection (13) to the other connection (14) via the second cavity (15) and via provided cavities (24) and recesses (25) in the safety valve cone (8), whereby a pressure equalizing occurs.

摘要： An apparatus for facilitating the removal of moisture from a compressed air tank has a tank with an interior volume, a tubular member positioned in communication with the tank and having an end adjacent the bottom of the tank, an air compressor interconnected to the tubular member for passing compressed air into the interior volume of the tank, a check valve positioned at an opposite end of the tubular member, a head pressure relief valve in communication with the tubular member, and a pressure switch cooperatively connected to the air compressor. The pressure switch opens the head pressure relief valve when an air pressure in the tank reaches a desired level so as to cause air and water in the tank to pass through the tubular member. The check valve serves to stop the passing of air and water after a period of time.
