This invention provides a gate valve, comprising a valve body and a valve needle assembly. The valve body has a valve cavity and a valve port communicating with the valve cavity. The valve needle assembly includes a screw and a valve needle disposed within the valve cavity. One end of the screw extends into the valve cavity and is movably connected to the end of the valve needle opposite to the valve port, allowing the screw to tilt relative to the valve needle. The inner wall of the valve cavity has internal threads, and the screw is threadedly connected to the inner wall of the valve cavity to drive the valve needle to move within the valve cavity and block or open the valve port. This gate valve, through the movable connection between the screw and the valve needle, allows the screw to tilt relative to the valve needle. Even if the screw tilts relative to the valve body due to thread clearance (coaxiality misalignment between the screw and the valve body), the valve needle will not tilt to the same degree relative to the valve body as the screw. Even in a tilted state, the screw can still drive the valve needle, and the valve needle seals the valve port, ensuring reliable driving of the valve needle and the sealing effect of the valve needle on the valve port.

It should be noted that like reference numerals and letters refer to like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
In the description of the present utility model, it should be understood that the azimuth or positional relationships indicated by the azimuth terms such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal", and "top, bottom", etc., are generally based on the azimuth or positional relationships shown in the drawings, and are merely for convenience of describing the present utility model and simplifying the description, and these azimuth terms do not indicate and imply that the apparatus or elements referred to must have a specific azimuth or be constructed and operated in a specific azimuth, and thus should not be construed as limiting the scope of the present utility model, and the azimuth terms "inside and outside" refer to inside and outside with respect to the outline of each component itself.
Spatially relative terms, such as "above," "upper" and "upper surface," "above" and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the process is carried out, the exemplary term "above" may be included. Upper and lower. Two orientations below. The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
In addition, the terms "first", "second", etc. are used to define the components, and are only for convenience of distinguishing the corresponding components, and the terms have no special meaning unless otherwise stated, and therefore should not be construed as limiting the scope of the present utility model.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
