摘要： A multi-stage pedal valve structure relates to a flow regulator on the valve opening located between the two compartments inside the body of the one-way pedal valve. The device includes a valve jacket, a piston rod, a graduating disc and a spring, while the valve jacket possesses a concave channel guide and a one-way tilting wedge. The graduating disc is a cylindrical unit on the opposite of the valve jacket. The piston rod comes in the form of a trapezoid, of which the outer section increases from top to bottom, and the middle section of the piston rod features circular channels, of which the end and the lower section come in increasing pitches and the perimeter of the lower section comes with slant blocks in reduced numbers and in even numbers in proportion to the channels on the valve jacket. The device keeps water from flowing.

摘要： A urine drainage tap is provided which includes an elongated passage having a barrel disposed therein and a control member located in the barrel which is moveable in relation to the barrel for defining an open and closed position. The lever arm is connected to the control member to permit movement of the control member. In an important aspect of this invention, the lever arm is moveable so as to extend along the passage in substantially opposite longitudinal directions relative to the passage when the control member is in the open and closed positions so as to avoid the tendency for the patient to inadvertently open or close the control member by leaning on the lever arm.

摘要： A rotary valve assembly of the ''''soft seat'''' type for use in fluid distribution systems such as gas or water. The valve assembly includes a valve housing having a fluid passage therethrough and a rotary valve structure including a valve operating member or stem extending exteriorly of the housing and a valve member for cooperating with valve seat means in the flow passage. Means are provided between the valve stem and the wall of the bore through which the valve stem extends for applying a controlled torque sufficient to render the valve structure inoperative by hand. Additionally, the torque controlling means prevents ingress of fluid or abrasive material to the interior of the valve assembly and also prevents corrosion between the valve stem and valve housing.

摘要： A rotary valve has a valve plug that is rotatable in a valve body about a rotational axis. Surface features of the valve plug and surface features of the valve body cooperate to provide a bearing by which the valve plug is rotatably supported with respect to the valve body. In addition, each of the valve plug and the valve body include a plurality of annular projections that encircle the plain bearing and axially overlap one another so as to form a labyrinth that surrounds the bearing. The labyrinth forms a fluid path that collects abrasive particles suspended in the fluid passing through the valve, whereby wear of the valve is reduced.

摘要： A construction unit (1, 2) forms part of a gas heater and includes a valve (9) which is actuatable by way of a stem (10). The stem (10) includes positive-fit device. The stem (10) is controllable from the outside via a tool which can be brought into engagement with the positive fit device. A detent engagement device (18, 27) holds the tool (21) in engagement with the stem (10), so that the valve is controllable without the aid of outside tools.

摘要： A valve assembly used in a manifold system fix processing fluid samples includes a body, a valve member, and a coupling assembly. The body defines a fluid passage and a valve passage in communication with the fluid passage and receiving at least a portion of the valve member therein. The valve member is selectively movable over a range of travel between an open position, in which fluid can flow through the fluid passage, and a closed position, in which the valve member occludes the fluid passage. The coupling assembly includes a coupling member and a retention lug. The retention lug is connected to one of the body and the coupling member. The other of the body and the coupling member defines a lug raceway configured to removably receive the retention lug therein to removably mount the coupling member to the body with the valve member being movably retained therebetween.

摘要： A valve for controlling the water flow in a sanitary line has a housing with a housing lower part in which a water supply channel portion, a control channel, and a water discharge channel portion are arranged in the flow direction. The control valve has a valve upper part with a head piece, which is arranged in a housing bore coaxially to the bore axis and to which a stator disc with a first ceramic surface is secured, and with a spindle, with which a rotor disc with a second ceramic surface is in engagement. The control valve also has an electric drive which is arranged in the housing upper part and which is in engagement with the spindle. Two seals which rest against the head piece and the spindle seal the control channel of the control valve from a housing upper part.

摘要： A water supply valve comprising a valve body having a first orifice and a second orifice, a rotatable valve shaft, and a handle. The rotatable valve shaft can be inserted into the first orifice or the second orifice, thereby converting the water supply valve from first configuration where the handle is on the left side to a second configuration where the handle is on the right side.
