    摘要： Some embodiments of the present invention provide an electronic expansion valve and assembling method of electronic expansion valve, the electronic expansion valve includes: a housing; a guide sleeve; a screw; a rotor being drivingly connected with the screw; and a valve needle assembly movably disposed in the housing, one end of the screw being connected with the valve needle assembly so as to drive the valve needle assembly to move axially by means of the screw. A guide segment and a press-fit segment which are in communication with each other are disposed between an inner wall of the housing and an outer wall of the guide sleeve, a spacing between the guide sleeve and the housing located on the guide segment is greater than a spacing between the guide sleeve and the housing located on the press-fit segment.

    摘要： A transmitter flange includes a flange body having a valve opening therein, the valve opening having a valve seat, and an internal valve configured to be retained in the valve opening. A retaining ring may be configured to thread into the valve opening to further retain the internal valve within the opening.

    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： In a valve device for selectively opening and closing a flow passage formed to open on a valve seat by a valve body through a resin-made seat, a hollow portion is formed on either one of the valve body and the valve seat and receives the resin-made seat therein, the resin-made seat has a thickness so that the resin-made seat partly protrudes from the hollow portion, and when the valve body is operated to close the flow passage, the resin-made seat is compressed to bring an end surface of the valve body into contact with the valve seat.
