For achieving the above object, the utility model provides following technological scheme:
A kind of control valve, comprise control valve main body, described control valve main body offers feed pathway and liquid outlet channel, described control valve main body is provided with electromagnetic coil assembly, described electromagnetic coil assembly includes electromagnetic coil, electromagnetic coil is elevated to drive with control spool and arranges, described control valve main body also offers holding cavity, the cavity wall of described holding cavity offers the first liquid entering hole, the second liquid entering hole and liquid outlet, first liquid entering hole is connected with feed pathway, liquid outlet is connected with liquid outlet channel, and the second liquid entering hole is communicated with feed pathway; Large valve body is provided with in described holding cavity, the diapire of described large valve body is also provided with secondary liquid outlet, the diapire of described large valve body is provided with little valve body, little valve body covers secondary liquid outlet, the sidewall of little valve body offers the secondary liquid entering hole be communicated with holding cavity, control spool and secondary liquid outlet abut against, and the medium and small valve body in inside of described holding cavity is also provided with Compress Spring, and the diapire of described large valve body is closed with liquid outlet.
As further program of the utility model: one end that described control spool abuts with secondary liquid outlet is tapered end.
As the utility model further scheme: described large valve body is slot type structure.
Compared with prior art, the beneficial effects of the utility model are: in the utility model when controlling spool and moving, secondary liquid outlet will be opened, to be flowed out by secondary liquid outlet at the process medium fluid opened, now the flow adjustment range of secondary liquid outlet is limited, in order to expand the flow control scope of control valve, large valve body will be driven to move when control spool continues unlatching, first liquid entering hole is opened gradually, now liquid outlet is open mode, realized the flow control flowing through fluid of the present utility model by the opening degree increasing by the first liquid entering hole gradually, extend the flow control scope of control valve, there is larger regulating ratio, and spool is by electromagnetic coil drived control, only need electromagnetic coil very little driving force entry/exit liquid mouth can be opened, there is not the problem of the keying difficulty brought because of medium temperature change, open and close and control flexibility and reliability, in addition, when the power-off of electromagnetic coil assembly, control spool and reset under the effect of Compress Spring, rapidly convenient, effectively improve sealing and the Security of control valve.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of control valve.
In figure: the secondary liquid entering hole of 1-feed pathway, 2-liquid outlet channel, 3-first liquid entering hole, 4-second liquid entering hole, 5-liquid outlet, 6-, the secondary liquid outlet of 7-, 8-control valve main body, the large valve body of 9-, the little valve body of 10-, 11-control spool, 12-electromagnetic coil assembly, 13-Compress Spring, 14-holding cavity.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of control valve, comprise control valve main body 8, described control valve main body 8 offers for fluid flow into or flow out feed pathway 1 and liquid outlet channel 2, described control valve main body 8 is provided with electromagnetic coil assembly 12, described electromagnetic coil assembly 12 includes electromagnetic coil, electromagnetic coil is elevated to drive with control spool 11 and arranges, described control valve main body 8 also offers the holding cavity 14 for accommodating control spool 11, the cavity wall of described holding cavity 14 offers the first liquid entering hole 3, second liquid entering hole 4 and liquid outlet 5, first liquid entering hole 3 is connected with feed pathway 1, liquid outlet 5 is connected with liquid outlet channel 2, second liquid entering hole 4 is communicated with feed pathway 1.
The fluid circulated in system from feed pathway 1 inflow control valve, then can enter into holding cavity 13 through the first liquid entering hole 3 and/or the second liquid entering hole 4, finally from liquid outlet 5 through liquid outlet channel 2 outflow control valve.
