  • Patent number: 10465802
    Abstract: A valve having an elongated main body and a substantially flat area defined within the valve between its first and second ends; wherein a stopping screw is received in said flat area so as to prevent extraction of the valve from a casing by applying a force against a portion of the valve once the valve is moved a predetermined number of turns. A method for inhibiting the turning of a valve having the steps of installing a threaded portion of a valve in a first threaded aperture through a casing, where the first threaded aperture receives the threads of the threaded portion of the valve; and threading a screw through a second threaded aperture in an exterior of the casing, where the screw, is disposed in a position to come into direct contact with the valve after a predetermined number of turns.

  • Patent number: 9095644
    Abstract: A fluid collector has a container, a T-tube, a first screw unit and a second screw unit. The T-tube is connected to the container and has a main pipe and a branch pipe. The first screw unit is mounted in an outlet end of the main pipe. The second screw unit is mounted in a connecting end of the branch pipe, which is connected to the main pipe. The branch pipe has a detecting opening far from the connecting end and connects to a detecting device. By changing the length of the first and second screw units, different detecting values of the pressure are adjusted according to containers with different capacities. Moreover, with the flowing resistance resulting from the first and second screw units, different pressure variations are performed when liquid or air passes through the T-tube. Therefore, massive hemorrhage is clearly identified to keep the patient safe.

  • Patent number: 8113235
    Abstract: Apparatus and methods for improved prosthesis donning, doffing, retention, and fit. A valve located in a prosthetic socket port includes a body, a core, a spring located partially within the core, a diaphragm, and a maintained operator. The operator includes a recess and a protrusion. The operator may be indexed to a displacement or vent position. When the operator is indexed to the displacement position, a tip of the core is pressed against the recess via the spring, and the diaphragm displaces any air that enters into the prosthetic socket when a load is applied to the residual limb. When the operator is laterally actuated, it is indexed to the vent position and the core tip moves from the recess to the protrusion. In this position, the diaphragm opens the socket cavity to the external atmosphere via valve vents, thereby facilitating prosthesis donning and doffing.

    Abstract: A safety air valve of a receiving bag includes an upper valve body, a valve seat and a valve gate. The upper valve body is installed inside the receiving bag. A first thread is formed at the protrusion stayed closely to the interior of the receiving bag. The first thread penetrates out the receiving bag; and a first main air channel is formed in the bottom of the first thread penetrating into the receiving bag so as to form a stepped valve opening on the top of the first main air channel. A second thread is formed at the valve seat corresponding to the first thread of the upper valve body. The second thread is screwed into the first thread and is positioned at the outer side of the receiving bag. The second thread has a press body corresponding to a first main air channel of the upper valve body.

  • Patent number: 7273065
    Abstract: A valve assembly for a dunnage bag wherein in the valve body a valve diaphragm is mounted on a shaft and is supported by a mounting bar such that the valve diaphragm may be reciprocally moved from the closed position to the open position by a simple axial push on the valve shaft. The valve shaft is retained in the mounting bar in an orifice and the shaft diameter is enlarged at its end distant from the valve diaphragm so as to generate a frictional force fit or lock in the open position to facilitate the removal of air from the bag. The valve may be released form the friction lock by the air pressure of a recharged bag and/or by the manual movement of the valve diaphragm and shaft axially toward the open end of the valve assembly.

  • Patent number: 7124770
    Abstract: The present invention relates to a mechanism for preventing damage to the actuator of a hydraulic choke valve in the event of excessive backpressure on the outlet of the choke. The backpressure relief device is applicable to a choke valve which meters flow from a high pressure annular region around the axially reciprocable choke throttling member into a low pressure exit channel coaxial with the throttling member. In particular, a shearable means is used to connect the reciprocable control shank of the actuator to the throttling valve member of the choke valve. In the event of excessive pressure on the exit channel of the choke valve, the shearable means will shear, thereby fully opening the valve and permitting the excessive pressure to escape. The shearable means is readily replaced so that the valve easily can be put back into operating condition.

  • Patent number: 7124774
    Abstract: A control valve for regulating flow of fluids passing through the valve. The control valve includes a body with an inlet, an outlet and a passageway through which the fluid passes from the inlet to the outlet. The control valve also includes a displaceable column provided with an internal and concentric bolt, the displaceable column is actuated by an actuator, the actuator positioned in a chamber that is connected to the body, a valve closure attached to the displaceable column. The displaceable column moves between a most retracted position, in which the inlet is fluidically communicating with the outlet, and a most pulled out position, in which the valve closure sealingly blocks the passage of fluid through the control valve.

  • Patent number: 6986360
    Abstract: A self-sealing valve comprises a valve housing having a fluid conduit, a valve seat, a flexible diaphragm and a support member. The valve housing is configured to pass fluid through the fluid conduit. The flexible diaphragm provides a self-seal of the fluid conduit, and comprises an area larger than an area of the fluid conduit and a periphery. The support member is configured to retain a portion of a flexible diaphragm. The support member and flexible diaphragm are configured to position the flexible diaphragm against the valve seat to seal the fluid conduit in a closed position of the self-sealing valve, and to facilitate movement of at least a part of the periphery of the flexible diaphragm in a first direction away from the valve seat to an open position.

Preferably, the valve has a unidirectional stepped valve housing. In the housing is a central bore that includes an upper portion, lower portion and a middle portion. The lower portion is narrower than the middle portion which in turn is narrower than the upper portion. The port is provided in the middle portion of said housing to facilitate connection of a nozzle to the valve. The valve has a t-stem with a lower end having a key-way and a cavity for receiving the upper portion of the valve seat. The valve seat provides the primary valve seal when the valve is closed. The upper portion of the valve seat has a geometry for engaging the t-stem to provide a locked assembly.

  • Patent number: 6808159
    Abstract: A nonrefillable valve is provided that allows for an initial filling of a container, but prevents subsequent refilling of the container. The valve operating assembly includes a valve stem and a valve core which is slidably received in the distal end of the valve stem. In a first position, the valve core resides above a rim or protrusion within the chamber. After filling of the container, a second position is defined when the valve stem is operated to force the valve core beyond the protrusion and in seating engagement with a valve seat, thus sealing the container. The valve is then selectively operated in a third or open position to discharge the container as desired. Subsequent refilling of the container is prevented by the force of fluid reentering the valve which forces the valve core to its seated engagement with the valve seat.
