The utility model is described in further detail below by specific embodiment combination attached drawing.

Fig. 1 shows one of the utility model compressed gas by-passing valve elevational cross-sectional view, correspondingly, Fig. 2 shows A kind of corresponding decomposition explosion figure of compressed gas by-passing valve, referring to Figure 1 and Figure 2 shown in, compressed gas by-passing valve packet It includes: valve head 1, armature 2, guide rod 3, spool 4, coil 5, sleeve 6, shell 7, outer enclosure 8, spring part 9 and upper stator 10.

Specifically, being fixedly connected between guide rod 3 and armature 2, and fixed between the first end of guide rod 3 and valve head 1 Connection；The winding of coil 5 is arranged on spool 4；Shell 7 coats spool 4 and coil 5；The injection molding of shell 7 is contained in outer enclosure 8. Outer enclosure 8 includes: outer enclosure ontology 81, ring flange 82 and connector 83, wherein ring flange 82 and connector 83 are distinguished It is connected between outer enclosure ontology 81；Sleeve 6 is set between spool 4 and armature 2.Also, it is recessed to be additionally provided with first on sleeve 6 Slot 61 is provided with first seal 62 in first groove 61, passes through the zero-clearance between the first containment member 62 and the first groove 61 Engaging guarantees the leakproofness that sleeve 6 is connect with ring flange 82, prevents that gas leakage occurs between sleeve 6 and ring flange 82, thus The leakproofness of compressed gas by-passing valve can be promoted.

The basic functional principle of compressed gas by-passing valve provided by the utility model is: connector 83 is set for connecting power supply It is standby, so that compressed gas by-passing valve obtains electric power support, when compressed gas by-passing valve is powered, effect of the armature 2 in electromagnetic force The lower linear movement for generating some direction, and then drive guide rod 3 and valve head 1 mobile in the same direction together, valve is in and beats at this time Open state, compressed air can flow back into the inlet end of air compressor by compressed gas by-passing valve, to prevent due to asthma Injury caused by the shake of vibration to turbo blade, while the reflux of compressed gas can also allow turbine to continue to rotate to reduce The lag of turbine when acceleration, and protect air throttle.When the power-off of compressed gas by-passing valve, in the gravity and spring part 9 of valve head 1 Under elastic force effect, valve head 1 is moved in the opposite direction and is pressed on a valve seat (client is not shown in the figure), to make gas Channel is closed, and valve 1 is in close state at this time.

In order to enable when compressed gas by-passing valve opens and closes, valve head 1 can be moved together with armature 2, at this It is fixedly connected between guide rod 3 and armature 2 in embodiment, the mode of being fixedly connected can be welding manner, riveting method, can also be with It is the mode of interference fit connection；Such as in such a way that interference is pressed, specially guide rod 3 is inserted into the mesoporous of armature 2 simultaneously It is pressed with 2 interference of armature；And it is fixedly connected between the first end of guide rod 3 and valve head 1.It can choose in the present embodiment The assembly method of rivet, this assembly method simple and stable can simplify amount of parts to a certain extent.

Outer enclosure 8 further comprises: outer enclosure ontology 81, and ring flange 82 and connector 83 are (for compressed gas Body by-passing valve powers on), wherein ring flange 82 and connector 83 connect between outer enclosure ontology 81 respectively.Specifically, flange Disk 82 and connector 83 connect each other can dismantle separation, ring flange 82 and connector 83 respectively with outer enclosure ontology It can be to be fixedly connected between 81；The advantages of designing in this way is: 1) can be adapted for different angle, different installing ports position The requirement in (i.e. the aperture of different clients requirement), can be flexibly matched with different clients；2) it is not necessarily to newly open the mold of integral molded plastic, Greatly shorten the development cycle.

Further, by quadric injection mould or can swash between ring flange 82 and connector 83 and outer enclosure ontology 81 The mode of photocoagulation achieves a fixed connection.

In specific implementation, upper stator 10 is set between armature 2 and outer enclosure ontology 81, is partially surrounded by spool 4, Assembly method between upper stator 10 and shell 7 is to be interference fitted and be riveted on one by the outer peripheral flange 101 on upper stator 10 It rises, upper stator 10 and shell 7 can be made of permeability magnetic material, and function is the magnetic force in order to enhance compressed gas by-passing valve.

In order to avoid the electromagnetic force that energization situation lower armature 2 generates drives guide rod 3 and valve head 1 insufficient for armature 2 It is moved along the axis direction of guide rod 3, sleeve 6 is set between spool 4 and armature 2.

In order to promote the electromagnetic force performance of compressed gas by-passing valve, sleeve 6 can be made of permeability magnetic material, 6, the sleeve Divide and surrounded and be nested on the periphery of armature 2 by spool 4, can be clearance fit between sleeve 6 and armature 2, avoid because of set Generated between cylinder 6 and armature 2 excessive frictional resistance influence armature 2 under the drive of electromagnetic force successfully in sleeve 6 along The axis direction of guide rod 3 is mobile, opens or closes state to control compressed gas by-passing valve and be in.

6 periphery of sleeve can partially be connect with spool 4, partially be connect with ring flange 82, so that it is guaranteed that compressed gas bypasses Valve can obtain enough electromagnetic forces when being in energized state, so that compressed air can be flowed back by compressed gas by-passing valve To the inlet end of air compressor, and then prevent the injury due to caused by the shake of surge to turbo blade.

In specific implementation, the first groove 61 can be annular groove, and the first containment member 62 can be O-ring seal, Those skilled in the art can according to actual needs, select the first groove and corresponding containment member of other shapes.
