摘要:
An object is to obtain a power storage device which can prevent infiltration of a fluid such as water through a gas exhaust tube. A power storage device of the present invention includes a power storage case housing battery cells, a gas exhaust tube communicating between the interior and exterior of the power storage case, and an infiltration prevention mechanism unit preventing a fluid from passing through the gas exhaust tube and infiltrating from the exterior into the interior of the power storage case. The infiltration prevention mechanism unit includes a valve case having a flow path communicating between the interior and exterior of the power storage case, a valve body housed in the valve case and selectively movable to a closed position and an open position, and a guide member guiding the valve body movably in the fluid flow direction.

An apparatus for controlling a flow of a fluid, such as a drilling fluid or drilling mud, is disclosed. The apparatus may include: a valve member; and a float member mechanically coupled to the valve member and configured to operate on the valve member when fully submerged in a fluid. The coupled float member is configured to increase flow through the valve member as a density of the fluid decreases and to restrict flow through the valve member as the density of the fluid increases.

The present disclosure is directed to a combination air valve that uses buoyancy to lift seals into place, preventing media from escaping from the valve. Once the seals are in place, pipeline pressure is used to open and close the valve. The combination air valve includes a piston assembly which includes a main disc, a piston head located above the main disc, a float below the main disc, and a float shaft joining the float to the piston. When no media is in the valve the float is at the bottom of the valve and the main disc is down, allowing gases to leave the valve. The float is lifted as media enters the valve, thus using buoyancy to lift the main disc into place, preventing media from escaping from the valve. Once the seals are in place, pipeline pressure is used to open and close the valve.

A sealing valve is provided for a sensor that includes a sensing element and a sensor opening that exposes the sensor element. The sealing valve includes a housing that is configured to be mounted to the sensor such that an internal channel of the housing fluidly communicates with the sensor opening. The sealing valve includes a float element configured to float along a surface of the liquid. The float element is configured to move within the internal channel between an open position and a closed position. The float element is configured to close the sensor opening to the internal channel in the closed position. The sensor opening is open to the internal channel when the float element is in the open position. The float element is configured to rise with the surface of the liquid within the internal channel toward the closed position.

A float valve assembly is provided which can be remotely retrofit to a pipe end located in a production tank. The valve assembly comprises a guide rod disposed axially in the valve assembly. A floating valve element of the valve assembly is coupled to the guide rod and is moveable with or axially along the guide rod. The valve assembly is remotely mounted on the pipe end by temporarily associating an installation tool with the guide rod to locate a fitting adapter of the valve assembly over the pipe end for sealably fitting the valve assembly to the pipe end. The guide rod can also be manually manipulated for moving the valve element away from the pipe end and locking the valve element in the open position for permitting flow of liquid through the pipe end. A method for manually locking the valve element in the open position is also provided.

A gas venting valve arrangement is disclosed, the gas venting valve arrangement comprising a valve housing having an inlet in a bottom region of the housing connectable to a fluid flow to be passing through a subsea pump or compressor, and an outlet for gas accumulating in a top region of the housing. A valve mechanism operating a movable valve body at the outlet' between open and closed positions. A floater in the housing actuating the, valve mechanism, wherein the floater is acted upon by a force means which is dimensioned to increase buoyancy of the floater with respect to a liquid phase of the fluid accumulating in a bottom region of the housing.

A condensate drain for a compressed air system is provided. The condensate drain includes a storage unit, an opening/closing member, and an adjusting member. The storage unit collects condensate and includes a storage main body defining a storage compartment within, and a storage panel sealing one side of the storage main body. The opening/closing member is provided at a side of the storage unit, to selectively open and close a passage through which condensate drains to an outside through an opening/closing valve. The adjusting member is provided at a side and within the storage unit, to adjust the opening/closing member. The opening/closing valve can be formed of an elastic material.

A beverages dispenser, particularly for carbonated beverages, comprises a cooled tank where beverage is stored, an inlet pipe to the tank, an inlet valve on the inlet pipe, a pump downstream the inlet valve for feeding a beverage to the tank in order to maintain a predetermined level wherein, an outlet pipe from the tank to a beverage dispensing nozzle, and an outlet valve on the outlet conduit. An auxiliary pipe is disposed between the inlet pipe downstream the inlet valve and the outlet pipe downstream the outlet valve and a control unit is adapted to close the inlet valve and to run the pump in order to empty the outlet pipe into the tank after the beverage is dispensed in order to prevent dripping.
