Rotary cycle switching air valve of multi-tower air dehumidifier

Abstract

The invention discloses a rotating circulating switching air valve of a multi-tower air dehumidifier. An upper valve cover and a lower valve cover are arranged at the top and the bottom of a cylindrical valve body respectively, and the centers of the upper valve cover and the lower valve cover are provided with center holes and sliding bearings. At least four identical switching air openings are evenly distributed at the same height in the middle of the valve body, and an upper air opening and a lower air opening are formed in one side at the upper portion and the other side of the lower portion of the valve body respectively. A valve element which is arranged at the corresponding position of the switching air opening in a valve body cavity comprises a valve rod, an upper valve plate, a lower valve plate, two arc valve clacks and air separating plates, the valve rod penetrates through the upper sliding bearing and the lower sliding bearing, the upper valve plate and the lower valve plate are in a circular or sector shape and are arranged on the two sides of the valve rod separately and horizontally, the distance between the upper surface and the lower surface is larger than the height of the switching air opening, the two arc valve clacks are connected with the two sides of the upper valve clack and the two sides of the lower valve clack respectively, the heights and the widths are larger than those of the switching air opening, and the air separating plates are connected with the upper valve plate and the lower valve plate and connected with the two arc valve clacks and the valve rod. The rotating circular face of the valve element is in small clearance fit with the circular face of a relevant section of the valve body inner cavity in a rotating mode.

Description

technical field [0001] The invention belongs to the field of air humidity regulation, and in particular relates to a rotary cycle switching air valve of a multi-tower air dehumidifier. Background technique [0002] In the existing technology, there is a "double-tower switching molecular sieve dehumidifier", the switching of a pair of air valves is a reciprocating synchronous switching, so the dehumidified space has large temperature and humidity fluctuations when the air valves are switched during work; "Three The air valve of the barrel cycle switching molecular sieve dehumidifier is a combination of three pairs of air valves. In addition to temperature and humidity fluctuations during switching, a complex piping system needs to be configured. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rotary cycle switching air valve of a multi-tower air dehumidifier that can switch between multiple towers, has simple an...
