Detailed Description
The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.
It will be understood that when an element is referred to as being "fixed" or "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
In addition, the terms of left, right, upper, lower, etc. in the embodiments of the present utility model are merely relative concepts or references to the normal use state of the product, and should not be construed as limiting. The implementation of the present utility model will be described in detail below with reference to specific embodiments.
The utility model discloses an accurate metering feeding valve, which comprises a cylindrical feeding cavity 1, wherein a rotating cavity 2 is arranged in the feeding cavity 1, the outer side wall of the rotating cavity 2 is attached to the inner side wall of the feeding cavity 1, and a servo motor 3 drives the rotating cavity 2 to rotate around the axial lead of the feeding cavity 1. An opening 21 is formed in the side wall of the rotating cavity 2, a feeding area is formed in the side wall of the feeding cavity 1, a plurality of feeding holes 11 are formed in the feeding area, and the feeding holes 11 gradually decrease along the rotating direction of the rotating cavity 2. The area of the opening 21 is smaller than that of the feeding area, and when the rotating cavity 2 rotates, the opening 21 sequentially rotates from the larger feeding hole 11 to the smaller feeding hole 11, so that the flow rate of the liquid flowing through the feeding hole 11 is gradually reduced. The top of the rotating cavity 2 is provided with a mounting flange 9 which can be connected with a rotary joint so as to facilitate the relative movement of the rotating cavity 2 and the pipeline. In this embodiment, the feed inlet 11 is square, and in other embodiments, the feed inlet 11 may be circular.
