    摘要： A drain valve for a compressed air system automatically discharges liquid separated from system air from a container in which the separated liquid is trapped when the trapped liquid activates the drain valve. A spring biases the valve element of the drain valve to an open position to drain the trapped liquid during system shut-down and is positioned in an outlet passage of the container so that the spring is accessible for replacement without dissassembly of the drain valve. A float in the container is responsive to the level of trapped liquid to open communication between the system pressure and a chamber on the upper side of a diaphragm type valve actuator to offset the system pressure in a chamber on the lower side of the valve actuator so that the spring and the pressure on the upper side of the valve actuator acting on the valve element moves the valve element to its open position for discharging the trapped liquid. The float includes a cup shaped member whose interior is in the form of an annular chamber with a continuous unbroken surface above its lower end so as to positively trap air therein which prevents excessive amounts of water from entering the float interior whereby water logging of the float is prevented.The valve element sealingly engages the diaphragm to seal the upper chamber from the lower chamber.

    摘要： In an automatic valving device, the combination comprises a container, an exhaust valve mounted in a lower portion of the container, an arrangement for actuating the exhaust valve, a pilot valve mounted in an upper portion of the container and coupled to the actuating arrangement, and an elongated guideway extending generally between the pilot valve and the exhaust valve. A float is movably mounted on the guideway and is operatively coupled to the pilot valve. The float is movable along a length of the guideway between an upper pilot valve opened position and a lower pilot valve closing position. Magnetic members are mounted on the guideway and the float respectively. At least one of the magnetic members is magnetized, and the magnetic members are shaped for magnetically attractive engagement therebetween. The magnetic members are disposed so as to effect such engagement at the lower float position to provide a snap action for the float upon removal of the float from its lower position toward its upper position.In a specific arrangement, a valve closure for the pilot valve can be provided with an assymmetric portion so that the valve closure is removed with a prying action to multiply the mechanical advantage of the valving device. In another arrangement the upper and lower float positions are sufficiently and spatially separated so that the float impactingly engages the pilot valve closure adjacent the upper position of the float to enhance the mechanical advantage of the valving device.

    摘要： A device for purging liquid of gas that may be present in a liquid flow line. There is included a valve means situated in a main flow line and a gas detection means which initiates the closing of the valve means when foul liquid is detected. Subsequently after the explusion of the fouling gases from the liquid, the detection means initiates the reopening of the valve means thereby allowing only clean liquid to pass through to the liquid discharge.
