Embodiment
In order to more fully understand technology contents of the present utility model, the technical solution of the utility model is further introduced and explanation below in conjunction with specific embodiment.
As depicted in figs. 1 and 2, a kind of dislocation type multichannel of the utility model control valve, comprise power unit 1 and the valve body parts 3 that connects with power unit 1, valve body parts 3 comprises that the spool 32 that connects with power unit 1 and hand are in the valve seat 31 that contains spool 32, valve seat 31 is provided with the annular cavity that is used for ccontaining spool 32 and is used for the annular chamber wall of connecting pipe, the annular chamber wall outside is provided with several interface tubes, and interface tube comprises liquid entering hole Y and a plurality of liquid outlet (I, II, III, IV, V, VI) spool 32 is provided with a wide mouthful of groove 321 and an a plurality of slot groove 322 that is offset to liquid outlet that docks with liquid entering hole Y; Each slot groove 322 increases one by one with the offset or dish of corresponding liquid outlet; Wide mouthful of groove 321 is connected with a plurality of slot grooves 322; Spool 32 is under the rotating force effect of power unit 1, each slot groove 322 (having six) staggers one by one and docks with corresponding liquid outlet, liquid entering hole Y is communicated with one by one with each liquid outlet, when spool is in position shown in Fig. 2, liquid entering hole Y is connected with liquid outlet I, after rotating to an angle during spool another mistake, then liquid entering hole Y is connected with liquid outlet II, so wait measuring angle inverse time rotation (individual liquid outlet is staggered one by one), can realize that liquid entering hole communicates one by one with each liquid outlet, realize the multichannel feed flow control of liquid.Aforesaid liquid entering hole and liquid outlet can oppositely use, and promptly liquid entering hole becomes liquid outlet, and each liquid outlet becomes liquid entering hole, can be used for the discharge opeing control of a plurality of passages like this.
