The invention provides a device for safely dispensing liquids, enabling to manage the state of a releasing valve according to the user, for example a vulnerable user such as a child.

A two-way or four-way water faucet dispenses near-boiling water on demand but has a safety interlock. A control valve assembly is attached to the faucet. The interlock uses two disks pressed into contact, each having a single projecting sector. One disk is fixed to the valve body. The other disk, fixed to the handle, slides against the first. The disks must be pulled apart by sliding the handle while it is being turned to superimpose the sectors and turn the control valve, connecting the faucet to the vented near-boiling water supply. A reed switch inside the fixed sector is activated by a magnet inside the rotatable sector and activates a near-boiling water pump.

According to one embodiment a gas tap is provided that includes a manually operable shaft having a first end coupled to a regulating element and a second end configured to be coupled to a knob that can be operated by a user. The shaft includes a first locking element, and the gas tap includes a second locking element. The shaft is rotational between an initial angular position and a final angular position, and is axially movable when it is arranged in the initial angular position between a first axial position in which the first locking element and the second locking element cooperate with one another, preventing the shaft from being able to rotate, and a second axial position in which the shaft is able to rotate. The user has to pull on the shaft in order to move it from the first axial position to the second axial position.

A faucet actuator torque increasing system and method for increasing torque applied to an actuator includes a grip. The grip has a perimeter wall with a continuous convexly arcuate shape. A coupler is removably mounted on the perimeter wall of the grip. The coupler includes a first segment and a second segment which are pivotably coupled to each other via a connector. The first and second segments move between a closed condition engaging the grip and an open condition for disengaging the grip. Each of the first and second segments has an interior surface. The interior surfaces abut the grip in the closed condition. A locking member releasably locks the coupler in the closed condition. A handle is integrally attached to and extends away from the coupler. A stop is attached to the coupler to abut against the grip when in the closed condition.

A flow rate adjusting device of the present invention includes a flow channel member and a valve mechanism. The valve mechanism includes a rod, a knob and a lock mechanism. The lock mechanism is switched by the knob moving in the traverse direction between a prohibited state in which the engaging portion is engaged with the to-be-engaged portion so that the rotation of the rod relative to the flow channel member is prohibited via the knob and a permitted state in which the engagement between the engaging portion and the to-be-engaged portion is undone so that the rod is permitted to rotate relative to the flow channel member.

An actuator for controlling a valve having a valve rod is provided. The actuator includes a manual override arrangement for manually moving the actuator spindle, the manual override arrangement including a locking element, an actuator spindle holder housing at least a portion of an actuator spindle. A guiding arrangement is adapted to guide the actuator spindle along the actuator spindle holder. In a normal operating mode the actuator spindle holder is locked to the locking element, and the actuator spindle is guidable along the actuator spindle holder via the guiding arrangement. In a manual override operating mode, the actuator spindle holder is unlocked from the locking element, and the actuator spindle holder is rotatable together with the actuator spindle via the guiding arrangement.

A paddle valve assembly includes a valve body having a cylindrical passage defined therein, a paddle member having a seal disposed about an entire circumference thereof, and a drive shaft and an idler shaft that rotatably connect the paddle member to the valve body. The paddle member is rotatable within the cylindrical passage about a rotation axis between open and closed positions. The drive shaft and the idler shaft are disposed in the valve body in line with each other along the rotation axis of the paddle member and are received in offset pockets defined in the paddle member. The paddle member extends at an angle with respect to the longitudinal axis of the cylindrical passage when in the closed position. The sealing engagement between the seal and the cylindrical passage of the valve body is continuous about the entire circumference of the paddle member.

A valve handle lockout device is configured to temporarily lock out a pull handle butterfly valve. The device includes an enclosure body, at least one lock hole, and a blocking wall. The enclosure body includes first and second enclosure portions having an opening at a proximal end of the enclosure body that is dimensioned to surround a base of the pull handle butterfly valve. The lock hole is configured to receive a locking member and thereby secure the device in a closed position on a handle of the pull handle butterfly valve. The blocking wall borders or is near to the opening and is configured to engage the pull handle butterfly valve when the enclosure body is secured in a locked position, thereby preventing removal of the device from the handle and the handle from being operated.
