The meaning of term in the present invention.
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
