The invention discloses an air draft head provided with a pipe joint; the circular sleeve part of the pipe joint is inserted on a connector and welded with the connector; the circular sleeve part of the pipe joint is provided with a plurality of spiral locking buckles which are uniformly distributed along the circumferential direction; the spiral locking buckles are spiral inward protrusions; andthe end, stretching towards a radial outward direction of a base component, of an end-cap screw positioning board is clamped on one side, facing the inside of the connector, of each of the spiral locking buckles. By adoption of the technical scheme, the air draft head is convenient to install, and is simple and beautiful; the air draft head is fixed spirally with positioning nuts, so the fixing effect is good, and the installation is firm; moreover, the size of a ventilation opening can be adjusted conveniently; in the air draft head, all parts are in common use; two types of ventilation pipes are adopted, namely a right-angle bent head and a 90-degree bent head; and the air draft head can be installed at any position to be subjected to air draft.
Description
technical field [0001] The invention belongs to the technical field of ventilation pipeline structure, in particular, the invention relates to a draft head with adjustable air volume. Background technique [0002] The air extraction head is used for air extraction in various closed environments, especially for sanitary units or engineering systems. The exhaust head needs to adjust the air volume, usually through the end cap. [0003] Below in conjunction with the accompanying drawings of this description, the prior art is analyzed: [0004] Such as Figure 1 to Figure 5 As shown, it is the structure of the early draft head. It includes a base component 1, an inner sleeve component 2, a snap ring 3, a sealing ring 4, an end cap 6, and an end cap lock nut 5. The outer edge of the base component 1 forms a ring-shaped curl toward the inner sleeve component 2 , and a sponge pad 7 is filled in the ring-shaped concave cavity of the curl. An end cap screw positioning plate 8 is ...
