摘要： A fluid regulator having a valve body defining an inlet, an outlet, a loading port, an access port, and a loading chamber disposed within the valve body and coupled to the loading port. A valve assembly is at least partially disposed between the inlet and the outlet and in communication with the loading chamber and is adapted to cooperate with the loading chamber to adjust fluid flow at the outlet by adjusting a fluid flow rate between the inlet and the outlet. A restrictor is at least partially disposed within the access port and the loading chamber and the valve assembly are adapted to be responsive to a change in loading pressure such that a modified rate is achieved and the restrictor is adapted to adjust a response speed in which the modified rate is achieved.

摘要： A vacuum valve with a housing having a valve seat, a closure member which, in a closed position, is pressed against the valve seat, and a manual actuator, by which the closure member is displaceable in a linear manner and which includes a screw transmission, which is actuatable by a rotational element and has a first driving part connected to the rotational element and a second driving part connected to the closure member. The driving parts have mating external and internal threads. A closing spring acts between the valve housing and the closure member. The first driving part is displaceable relative to the valve housing parallel to the closing direction, and with the closure member in the open position, the closure member is held against displacement in the closing direction by a supporting stop against which a stop face of the rotational element or of the first driving part abuts.

摘要： A gas sampling bag valve with sealing rings moving back and forth to control a lateral gas nozzle is easy to operate and not prone to leaking gas. The connection portion between the valve and the membrane of the gas sampling bag comprises, from exterior to interior sequentially, a valve body with the lateral gas nozzle, a rubber gasket, the membrane of gas sampling bag and a bottom disc of a fastener, and the valve is fixed to the gas sampling bag by way of clockwise rotating the fastener. The sealing ring of top cover that controls a switch and is close to a knob prevents gas from leaking from a thread gap between the top cover control switch and the valve body.

摘要： A water diverting device comprises an inlet, two outlets, an upper and a lower sealing seats respectively for the outlets. The device further comprises a water diverting switch that fits with the sealing seats and used to switch over the outlets. The switch includes a sliding shaft and fixed base with a sliding through hole. The switch is provided with a retaining hook for holding the sliding shaft up and down direction. On the surface of the sliding shaft, there are the first and second stop positions for the hook part of the hook, first and second unidirectional slide channels. The switch has a spring pushing the shaft from its head towards its tail. The head of the shaft connects with a valve core, and positions of the sealing seats correspond with travel of the valve core. The water discharge direction is changed over by a diverting switch.
