The safety valve for avoiding gas pressure excessive is set, safety valve includes the exit passageway being connected to exhaust passage N, can lead to along safety
The poppet 14 that road moves up and down and the second spring 141 for sealing exit passageway and exhaust passage N;Second spring
141 are set to the peripheral part of poppet 14, and when gas pressure is greater than preset value, poppet 14 overcomes the elasticity of second spring 141
Power moves up so that exit passageway is connected to exhaust passage N.
Preferably, the value range of the preset value of gas pressure can be 0.38 ± 0.02MPa, when gas pressure is greater than in advance
If second spring 141 is compressed when value, move up poppet 14, the 4th sealing surface H is opened, thus gas enters safety
Thus channel simultaneously enters exhaust passage N, be discharged by gas vent R;When the gas pressure in rear valve body 12 restores to regime values,
141 return of second spring, poppet 14 drop to home position, and the 4th sealing surface H is closed, and control valve works normally.
Preferably, safety valve is threadedly coupled by safety valve bolt 13 with rear valve body 12, while safety valve bolt 13 is with after
The junction of valve body 12 is coated with high-intensitive, high-air-tightness screw thread glue.
In another embodiment, as shown in Figure 1, Retarder control valve provided by the invention includes outside valve body
Shell, end cap 3, the core assembly being set to inside valve shell etc., wherein valve shell includes front valve shell 2 and rear valve body 12, preceding
Valve body 2 is provided with decompression hole T, air inlet P and connector 1, and wherein connector 1 is for obtaining current signal, connection power supply;Preceding valve
Body 2 is internally provided with the circular hollow cavity of multiple and different diameters and depth, location hole and multiple boss is additionally provided with, for installing
Proportion electro-magnet 4 and core assembly, proportion electro-magnet 4 include push rod 41, thrust controller 42 and adjustment spring, core assembly packet
Central spindle 6, gas nozzle nut 9, the first spring 61, third spring 62, bellows 7 and pedestal 8, push rod 41 is included to connect with sliding block 5, it is sliding
Face of the gasket for sealing in block 5 is primary sealing area F, and the sealing surface that gas nozzle nut 9 is bonded with pedestal 8 is the second sealing
Face E;Rear valve body 12 is provided with piston 10, exhaust passage N, gas vent R, working hole Q and safety valve;Valve shell is installed on damping
On assembly 15;Gasket on preferred sliding block 5 is rubber gasket.
Preferably, in order to guarantee the air-tightness of product, between pedestal 8 and valve shell, base plate 11 and valve shell it
Between be not provided with O-ring seals, and pedestal 8 and base plate 11 are provided with the groove for placing O-ring seals.
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.
