Detailed Description
The following further description is made with reference to the embodiments shown in the drawings.
In the multi-stage linkage sleeve valve shown in the attached drawings, an inlet channel 11 and an outlet channel 7 are arranged at the bottom of a valve body 2; the outer sleeve 5 is arranged between the inlet channel and the outlet channel, and the circumferential surface of the outer sleeve is provided with a plurality of through holes 5.1 for medium (steam or/water) circulation; the valve rod 3 is vertically arranged in the valve body and can move (cannot rotate) in the axial direction; the power mechanism 1 installed on the top of the valve body is used for driving the valve rod. The above structure is similar to the existing sleeve valve.
The utility model discloses an improvement is: the end face of the bottom end of the outer sleeve is closed, and a channel opening 5.3 facilitating medium circulation is formed in the center of the end face; the upper surface of the end face of the bottom end is provided with an inner sleeve 5.2, the inner sleeve is an annular body which is coaxially arranged with the outer sleeve, and the circumferential surface of the annular body is provided with a plurality of through holes so as to facilitate medium circulation; the outer circumferential surface of the inner sleeve and the inner circumferential surface of the outer sleeve keep a distance (the distance is selected according to the requirement); a movable sleeve group is fixed at the bottom end of the valve rod and can axially move in the space; the movable sleeve group comprises a large sleeve 6.1 and a small sleeve 6.2 which are coaxially arranged, the inner circumferential surface of the small sleeve can be in sliding fit with the outer circumferential surface of the inner sleeve, and the outer circumferential surface of the large sleeve can be in sliding fit with the inner circumferential surface of the outer sleeve; in addition, the end surface of the bottom end of the small sleeve and the channel port form a valve port which can be opened and closed, so that the medium flow passing through the channel port is controlled. The end face of the bottom end of the small sleeve also extends downwards to form a small annular body 6.3, and the circumferential surface of the annular body is provided with a plurality of openings for medium circulation; the outer circumference of the small ring-shaped body is matched with the inner diameter of the passage opening.
Further, the outer sleeve is disposed at the intersection of the inlet passage and the outlet passage (isolating the inlet passage and the outlet passage from each other), and is arranged coaxially with the valve stem. The outer circumference of the outer sleeve is positioned in one of the channels; the channel port on the bottom end surface of the outer sleeve is communicated with the other channel, and the top end surface of the outer sleeve is sealed by the inner wall of the valve body.
The power mechanism comprises a motor and a screw rod mechanism driven by the motor.
The utility model discloses a theory of operation is:
when the valve is closed, the valve rod drives the movable sleeve group to sink until the small annular body is embedded with the upper opening edge of the passage opening, so that the inlet passage and the outlet passage are closed (the valve opening is closed); the valve is thus in a closed state.
When the movable sleeve group needs to be opened, the power mechanism is started, and the movable sleeve group is pulled up through the valve rod; the blocked through holes on the inner sleeve and the outer sleeve are gradually increased, and the medium in the channel at the outer circumference part of the outer sleeve can sequentially pass through the through holes on the outer sleeve and the inner sleeve and then enters another channel (or the medium moves reversely) at the bottom end surface of the outer sleeve through the opening hole on the small annular body; the movable sleeve group is further lifted until the bottom end of the annular body exceeds the highest row of through holes of the outer sleeve, and at the moment, the medium in the channel at the outer circumferential part directly enters another channel at the bottom end surface of the outer sleeve from the channel opening (or the medium reversely moves) after passing through the through holes on the outer sleeve and the inner sleeve in sequence; the flow reaches a maximum value.
