Abstract
The utility model relates to a direction valve, in particular to a direction valve which accomplishes guides in various directions. The direction valve is provided with a valve core 1 which is provided with an L-shaped passage communicated with a tee joint T interface 3 of a valve seat 2, wherein, the valve core 1 is exteriorly connected with a rotary shaft 4. The rotary shaft 4 in exterior connection with the valve core 1 is connected with a bi-direction electric machine, so that the utility model can accomplish the guides of air flow or water stream in two different directions. The utility model is used for drying the air inside the dried body, when the internal temperature of the dried body exceeds the prescribed scope; the valve core rotates to an air passage inside the dried body to accomplish the intra-body drying purpose for the dried body. When the temperature or the humidity of the desiccant exceeds the prescribed scope, the valve core rotates to the desiccant regeneration passage to recover function to absorb the humidity.
Description
Technical field
The utility model relates to a kind of selector valve of realizing the different direction conducting.
Background technique
Present existing selector valve has only the positive and negative function that is conducted, and for multinomial function conversion, obviously can not meet the demands.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind ofly can realize the conducting of different direction function, selector valve simple in structure.
The implementation of the utility model purpose is that selector valve has " L " shape passage that communicates with valve seat 2 three ports 3 in the middle of the change-over valve core 1, the spool 1 outer rotatingshaft 4 that connects.
The spool 1 outer rotatingshaft 4 that connects is connected the utility model and the conducting that can realize two different direction air-flows or current with either-rotation motor.The utility model is specially adapted to the drying of dry body inner air, temperature and humidity when the body inside that is dried surpasses predetermined range, the interior air of the body that is dried reaches the siccative drying that the port that is communicated with dehumidifier is sent into dehumidifier through the port that selector valve communicates with dry body, and then get back to the body inside that is dried through two above-mentioned ports, through repeatedly circulation, thereby reach the purpose of dry body inner drying.Temperature and humidity as siccative surpasses predetermined range, and heating equipment heats siccative, and the water evaporation in the siccative reaches the port discharge that communicates with atmosphere through the port with dehumidifier is communicated with of selector valve, and final siccative finish-drying recovers moisture absorbing.
The utility model is simple in structure, cost is low; The dehumidifying of employing siccative, siccative is renewable, and it is uncontrolled to dehumidify, and service time is long, and effect on moisture extraction is good; In working lipe, can be suitable for occasion uses such as vehicle-mounted at siccative.

Embodiment
With reference to Fig. 1,2, " L " shape passage that communicates with valve seat 2 three ports 3 is arranged, the spool 1 outer rotatingshaft 4 that connects in the middle of the utility model change-over valve core 1.
With reference to Fig. 3 a when changeover valve core 2 turns to position shown in the figure, the port above the selector valve and the right port conducting; With reference to Fig. 3 b when changeover valve core 2 turns to position shown in the figure, the port below the selector valve and the port conducting on the right.
The rotation of the spool of selector valve is finished by the control motor by correlation control unit.
Claims (1)
1. selector valve is characterized in that in the middle of the change-over valve core (1) " L " shape passage that communicates with valve seat (2) three ports (3) being arranged, the outer rotatingshaft (4) that connects of spool (1).
