摘要： A champagne tower-type multi-stage throttle control valve includes a valve body, a valve cover, a throttle sleeve, and a valve core. A sleeve cavity of the throttle sleeve is shaped as a stepped hole with two or more layers. The valve core is shaped as a stepped shaft with two or more layers coaxial with the throttle sleeve. The number of shaft shoulders of the valve core is smaller than or equal to the number of hole shoulders of the sleeve cavity of the throttle sleeve, such that each set of shaft shoulders of the valve core in an axial direction can form a sealing surface fit with corresponding hole shoulders of the throttle sleeve. A flow channel groove is axially or obliquely formed on each of the hole shoulders of the throttle sleeve and/or the shaft shoulders of the valve core.

摘要： The present invention relates to a pressure resistance valve structure, which comprises a front valve seat body, a pressure resistance valve core body and a rear valve seat body. The pressure resistance valve core body is closed or released from the closed state relative to the front valve seat body, to control the export of liquid or gaseous fluids. The overall composition of the present invention is simple in structure, reducing the risk of component failure after long-term use, so as to achieve the effect of structural stability and good convenience of use.

摘要： A flow rate adjusting valve, in which a needle valve is arranged so as to face a fluid passage of a main body, is equipped with a handle configured to enable a rotational operation to be performed manually, an electric motor configured to be operated remotely, and a motive power transmission mechanism that selectively switches between a rotational operating force of the handle and a driving force of the electric motor, and to transmit the force to the needle valve. The switching is performed by causing the handle to be moved in a direction of an axis of rotation.

摘要： A multi-profile adapter assembly is disclosed for connecting a pressurized fluid source to two or more different fittings. The adapter assembly includes an injector connector removably attachable to a hose connected to a pressurized fluid source and including an internal conduit for channeling a flow of pressurized fluid. An inner housing is connected to the injector connector and includes a channel leading to a second opening and a cavity configured to receive an access fitting on an AC system. A one way valve controls flow from the conduit in the injector connector into the inner housing. An adapter is connected to the inner housing and includes a first contour configured to engage with a first fitting and a second contour configured to engage with a second fitting. The inner housing and adapter are movable relative to one another for changing the location of the first contour and second contour.

摘要： A valve device includes a valve main body having a valve chamber, and inflow and outflow passages communicating with the valve chamber; an annular valve seat surrounding an opening from the inflow passage to the valve chamber; and a valve element moved to contact with and separate from the valve seat. One of the valve seat and the valve element includes a contact surface, and the other of the valve seat and the valve element includes an annular raised rib. The rib has at a top thereof an annular sealing part contacting the contact surface to provide sealing between the valve element and the valve seat. The sealing part includes an annular flat surface extending parallel to the contact surface, and two annular inclined surfaces provided adjacent to the flat surface on both sides and inclined to the flat surface to extend in a direction away from the contact surface.
