Pressure process is as shown in Figure 2 and Figure 5, in pressure process, changes the electric current for flowing through proportion electro-magnet 4 by controller Size, so that push rod 41 is moved right, push rod 41 pushes sliding block 5 mobile during moving right, not with current signal Disconnected to increase, thrust and the displacement of push rod 41 are gradually increased, and the sealing rubber pad compression central spindle 6 on sliding block 5 is subjected to displacement, while close Envelope rubber pad is contacted with primary sealing area F, seals primary sealing area F, central spindle 6 is connect with gas nozzle nut 9, therefore central spindle 6 can Push gas nozzle nut 9 mobile, make the secondary sealing area E opening clearance of gas nozzle nut 9 Yu first through hole, the gas of air inlet P by This enters, and gas enters rear valve body 12 by base plate 11;As the displacement of push rod 41 is continuously increased, gas in air inlet P Flow is gradually increased, and the pressure of gas increases therewith in 12 chamber of rear valve body, is influenced by gas pressure, and piston 10 moves right, Third sealing surface K is sealed, and exhaust passage N is closed, and gas is exported by working hole Q to retarder, can be by adjusting push rod 41 displacement makes push rod 41 be fixed to different location, to obtain the gas of different pressures.
Decompression process is as shown in Figure 3 and Figure 4, as the current signal for flowing through proportion electro-magnet 4 is gradually reduced, push rod 41 Thrust is gradually reduced, and sliding block 5 is gradually reduced the thrust of central spindle 6, in 7 elasticity of the first spring 61, third spring 62 and bellows Under the action of active force, pushing is gradually moved to the left, and the sealing effect of primary sealing area F weakens, and partial gas is close by first Cover F flows into the chamber of 2 front end of front valve shell, and is discharged from decompression hole T, and front and back valve body 12 forms pressure difference, and piston 10 gradually returns Position, exhaust passage N are opened, and gas is discharged by gas vent R, meanwhile, central spindle 6 is gradually brought to normal position, gas nozzle nut 9 and base The secondary sealing area E gluing, sealing of seat 8, gas flow are gradually reduced, and the pressure of gas gradually decreases in valve body.
It needs to be illustrated, primary sealing area F provided by the invention, secondary sealing area E, third sealing surface K and Four sealing surface H, the first spring 61, second spring 141 and third spring 62, first through hole, the second through-hole, third through-hole and the 4th In through-hole first, second, third and fourth simply to illustrate that position difference, there is no sequencing point.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other The difference of embodiment, the same or similar parts in each embodiment may refer to each other.All realities provided by the present invention Any combination mode of example is applied in the protection scope of the invention, this will not be repeated here.
Retarder control valve provided by the present invention is described in detail above.It is used herein specifically a Principle and implementation of the present invention are described for example, and it is of the invention that the above embodiments are only used to help understand Method and its core concept.It should be pointed out that for those skilled in the art, not departing from the principle of the invention Under the premise of, it can be with several improvements and modifications are made to the present invention, these improvement and modification also fall into the claims in the present invention Protection scope in.
