摘要： The invention provides a low pressure liquid dispensing valve with the valve stopper movable from a closed position to an open position in the direction of flow of the fluid and having a downstream convergingly tapered surface extending beyond the outlet so that the ultimate surface over which the fluid flows upon exiting the valve, through the well known ability of the flowing fluid to follow the contour of the adjacent surface, causes the stream to reform into a unified flow path of relatively small diameter with respect to the outlet.

摘要： A fluid injection device includes a housing and a valve stem. The housing includes an inlet arm having an inlet orifice for receiving a feeder fluid. An outlet arm has an outlet orifice to discharge a mixed fluid. A venturi tube is between the inlet and outlet arms. The inlet arm, veturi tube and outlet arm define a nonlinear fluid pathway where the venturi tube redefines a portion of the nonlinear fluid pathway as a constricted fluid pathway. A diverter port is used to divert a portion of the feeder fluid from the inlet arm into the container and an injection port is used to receive product from the container. A valve arm is collinearly aligned with the venturi tube and the valve stem is positioned within the valve arm and adjusts the volume of the constricted fluid pathway.

摘要： A regulating slide valve apparatus having a housing which forms a duct through which a gaseous or liquid medium can flow having an inlet longitudinal portion, an outlet longitudinal portion, and an adjustable regulating element for varying the flow cross section of the duct and adjusting the throughflow rate. A seat ring element is provided in the duct, the regulating element has a first longitudinal portion which has a circular cross section with diameters that vary in the longitudinal direction, and the regulating element is adjustable in the longitudinal direction of the duct along an adjustment travel. In a closure position the regulating element lies against the seat ring element and closes the duct and, in an open position, forms an annular gap through which flow can pass, with the seat ring element. The varying diameters along the first longitudinal portion of the regulating element are configured such that the change in the cross-sectional area through which flow can pass, of the annular gap with the adjustment of the regulating element in the longitudinal direction, is such that the volume flow through the annular gap varies approximately linearly with the adjustment of the regulating element along the adjustment travel.

摘要： A flow rate regulation valve comprising a housing (11) formed with a valve hole (13), a needle valve (60) moved relative to the valve seat (16) in the housing, and a flow rate adjust knob (40) mounted at the proximal end of the needle valve extending from the housing, wherein the needle valve is moved relative to the valve seat by rotating the flow rate adjust knob thereby regulating the flow rate of fluid flowing through the valve hole, the flow rate regulation valve further comprising a knob fixing means (35) for stopping the rotation of the flow rate adjust knob. As a result, the flow rate is prevented from being changed accidentally by a user or the like. Further, the value may have a seal adjust means (20) adjusting the sealed state between the housing and the needle valve. The seal adjust means may be formed as a part of the housing, and may be fixed to the housing by a fixing pin (15).

摘要： A flow rate regulation valve (10) comprises a housing (11) formed with an axial hole (14) and a valve hole (13) communicating with the axial hole, a needle valve (60) adapted to move within the axial hole relative to a valve seat located between the axial hole and the valve hole, and a flow rate adjust knob (40) mounted at the proximal end of the needle valve extending from the housing. The needle valve is moved relative to the valve seat by rotating the flow rate adjust knob thereby to regulate the flow rate of the fluid flowing through the valve hole. A first valve body (67) is arranged at the forward end of the needle valve and a second valve body (65) extends from the end surface (67a) of the first valve body. The cross section of the first valve body is larger than that of the second valve body, so that at the time of closing the flow rate regulation valve, the end surface of the first valve body abuts with a valve seat (16) located between the axial hole and the valve hole, and the second valve body is inserted in the valve hole. As a result, fluid can be supplied in a stable fashion with a flow rate that is linearly maintained.
