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

The rotating circulating of multitower airdryer switches air-valve

Technical field

The invention belongs to humidity of the air and regulate field, the rotating circulating that is specifically related to a kind of multitower airdryer switches air-valve.

Background technique

In prior art, have " Dual-tower switching molecular sieve dehumidifier ", its a pair of air-valve switch to reciprocating synchronous switching, so dehumidified space has larger temperature and humidity to fluctuate when air-valve switches when work; The air-valve of " three barrels of cyclic switching molecular sieve dehumidifiers " is the combination of three pairs of air-valves, exists temperature and humidity fluctuation during except switching, also needs to configure complicated pipe-line system.

Summary of the invention

Technical problem to be solved by this invention be to provide a kind ofly can multitower rotating circulating switch, simple and reliable for structure, can effectively avoid the rotating circulating of the multitower airdryer of temperature and humidity fluctuation to switch air-valve when operating steadily, working.

The technological scheme that realizes the object of the invention is that a kind of rotating circulating of multitower airdryer switches air-valve, the top of columnar valve body is provided with bonnet, the bottom that center has center hole and sliding bearing is housed and is provided with the bottom flange that center has center hole and properties of journal bearing lubricated is housed, and the opposite side that the side that the sustained height place, middle part of valve body is evenly equipped with at least 4 same switching air ports, top is provided with uptake, bottom is provided with lower air port; The spool that valve rod passes sliding bearing and properties of journal bearing lubricated is housed in the chamber of valve body, and spool is located at and the corresponding part, position of switching air port; Top one side of spool is provided with the semicircle of horizontal or the semicircle or fan-shaped lower valve plate that fan-shaped upper valve plate, bottom opposite side is provided with horizontal, and the distance between the upper surface of upper valve plate and the lower surface of lower valve plate is greater than the height that switches air port; In the both sides of upper valve plate and lower valve plate, be respectively equipped with the height and the width that interconnect with it or rabbet and be greater than the arc flap that switches air port height and width, between the inwall of two arc flaps and valve rod and on be also provided with wind isolation board between the lower surface of valve plate and the upper surface of lower valve plate, the disc of solid of rotation and the relevant disc in body cavity stage casing that the upper valve plate of spool, lower valve plate and two arc flaps are combined into are that little gap is rotatably assorted.

The present invention can be upper and lower symmetry status by two the identical rotating circulatings switching of structure air-valves and coaxially arrange when reality is used, its two relevant valve rod ends are adjusted to when synchronous and connect with coupling lever location in switching position, synchronously switch following while turning cyclic switching guaranteeing.

The present invention has positive effect: the rotating circulating of (1) multitower airdryer of the present invention switches air-valve can realize the gradual cyclic switching of multitower, the fluctuation of temperature and humidity while avoiding dehumidifier operation.

(2) what the rotating circulating of multitower airdryer of the present invention switched that air-valve reduced regeneration hot blast and dehumidifying wind alters wind phenomenon, has improved efficiency of energy utilization and has made the degree of depth dehumidifying of dehumidifier have better technical support.

(3) the present invention is simple in structure, reasonable in design, can extend the trouble-free life limit of dehumidifier.
