摘要： Disclosed is a water stop valve. A water inlet channel, a water outlet channel, and a water sealing surface are formed in a valve body. A valve stem has a middle portion movably disposed in the valve body and a lower portion mounted in a back-pressure hole of a water-plugging stopper. A back-pressure cavity is formed above the water-plugging stopper. A sealing end surface matching the back-pressure hole is formed on the valve stem. When in use, the valve stem drives the water plugging stopper to move downwards, the sealing end surface blocks the back-pressure hole, and the water plugging stopper blocks the water sealing surface, such that the water enters the back-pressure cavity, and the water pressure enables the water-plugging stopper to block the water sealing surface to stop the water. The water stop valve stops a water inlet valve from feeding in water in a timely manner.

摘要： A specific gravity valve, has a floating valve member with a specific gravity that is less than the specific gravity of a first liquid and greater than the specific gravity of a second, heavier liquid. A valve seat is associated with the floating valve member. A valve member retainer retains the floating valve member and permits limited vertical movement of the floating valve member between an open position away from the valve seat and a closed position engaged with the valve seat, such that in the open position, fluid flow through the respective outlet is permitted, and in the closed position, fluid flow through the respective outlet is prevented. The specific gravity valve may be used with a production tank to prevent an unintended draw off of the wrong fluid component in the tank.

摘要： The fuel cutoff valve includes a casing and a float mechanism. The float mechanism is composed of an outside float and an inside float. The outside float includes an outside float body of round tubular shape having a float chamber that connects with a valve chamber via a through-hole formed in its upper part; and an outside valve portion disposed on the upper part of the outside float body and adapted to open and close an outside connecting passage. The inside float has an inside float body accommodated and adapted to rise and fall within the float chamber, and an inside valve portion disposed on the upper part of the inside float body and adapted to open and close the inside connecting passage through the through-hole.

摘要： A liquid level control apparatus for a flush tank includes a valve mechanism communicating with a fill tube and operable between open and closed conditions, two floats, at least one of which is coupled to the valve mechanism for closing it when the at least one float reaches a predetermined height, and structure interconnecting the floats so as to substantially prevent their vertical movement until a predetermined liquid level is reached corresponding to the predetermined height, thereby causing sudden movement of the at least one float to the predetermined height and sudden closing of the valve.

摘要： A gated proportional control valve is disclosed which allows both high-flow proportional dispensing and precision low flow. The design includes one or more controlled diameter and controlled-shape orifices in the control path, which, when both of the gate valves are opened, allow for consistent low flow dispensing. The gate valves can alternatively be opened or closed to allow proportional dispensing or valve closure. The invention is particularly useful in a fuel dispensing apparatus.

摘要： Disclosed is a leak-proof device for a water inlet valve. A control valve is installed in a valve body for opening and closing a water inlet channel and a water outlet channel. An outer water tank and a leak-proof water tank are installed on the valve body. An inner water tank is disposed in the outer water tank, with the height of the inner water tank being lower than that of the outer water tank. The leak-proof water tank is in communication with the inner water tank via a water-passing channel A lever is pivotally connected to the valve body. Two ends of the lever are connected with an outer float and an inner float. The inner float is provided with a plug that is movable to block the water-passing channel. The leak-proof float is connected to the control valve.

摘要： A fully-integrated, flow-control module for top-fill fuel tanks operates with a fuel line attached that supplies fuel under pulsating pressure. There are two bleed paths in the module, which open and close sequentially in response to the position of a fuel float within the module. In order for a main valve plunger, which controls fuel entry into the tank, to fully close, both bleed paths must be closed. A first bleed path closes first, followed by closure of the second. For the main valve plunger to fully open, both bleed paths must be open. The second bleed path opens first. Movement of the main valve plunger is controlled by both a biasing spring and pressure beneath the plunger. Pressure beneath the plunger builds up to a level sufficient for the biasing spring to fully close the plunger against a valve seat when both bleed paths are closed.

摘要： An opening/closing device according to the present invention includes a gate, a fall prevention unit, a support release unit, a first float, a floating prevention unit, a second float, and a floating prevention release unit. The gate receives a flow of fluid, and is able to fall down toward a downstream direction of the flow. The fall prevention unit supports the gate, thereby preventing the gate from falling down. The support release unit releases the support for the gate by the fall prevention unit. The first float is arranged on an upstream side of the gate, is arranged on one of the left side and the right side of the gate viewed from upstream, and is less in the specific gravity than the fluid. The floating prevention unit prevents the first float from floating.

摘要： A heated humidifier including an autofeed mechanism disposed within a humidifier chamber. The autofeed mechanism includes a housing, a float, a stem, and a sealing body. The housing defines an inlet, an outlet, a first chamber connected to the inlet, and a second chamber connected to the outlet and the first chamber by a channel. The float moves within the second chamber with the stem projecting therefrom and through the channel. The sealing body is within the first chamber and cooperates with the stem. In an open state, the sealing body is displaced from the channel to permit filling of the humidifier chamber. In a closed state, the sealing body seals the channel to prevent liquid flow to the outlet. A location of the sealing body relative to the channel is controlled by the float as a function of a humidifier chamber liquid level.
