Part 21 is saved towards the direction of valve block 22, the distance of first through hole 221 to the free end of valve block 22 is equal to the chi of first through hole 221
It is very little, wherein, the size of the second through hole 222 is 1/5th of the size of first through hole 221.Certainly, embodiment of the present utility model
In the size of the second through hole 222 be not limited to as 1/5th of the size of first through hole 221, can be arbitrary dimension and shape
Through hole, the size and shape of second through hole 222 can be designed according to the throttling situation of pressure-regulating valve 100.
In the utility model, when needing Opening pressure regulating valve 100, by regulating and controlling knob 211 so that knob 211 revolves
Enter in the first adjusting cavity 201, so as to which knob 211 drives elastic component 212 to compress and compressing rear-guard movable valve block 22 to a certain extent
Moved towards valve body 21, until valve block 22 is held in the bottom of host cavity 14, now bellows 23 is in compressive state, and air-flow leads to
Road is switched to the first through hole 221 corresponding to valve block 22 by the second through hole 222 of corresponding valve block 22.Adjusted when needing to close the pressure
When saving valve 100, regulation and control knob 211 is so that knob 211 screws out out of first adjusting cavity 201, so as to which now elastic component 212 is gradually extensive
Again to original state, because bellows 23 is still in compressive state, the first through hole 221 for being still now valve block 22 corresponds to valve body
1 gas channel, the fraction in gas channel is entered in the second adjusting cavity 202 by passage 13, in the second adjusting cavity
When air pressure in 202 reaches a preset value, gas pressure in the top of bellows 23 so that bellows 23 is stretched, now ripple
Pipe 23 moves towards the first adjusting cavity 201 in the lump with movable valve block 22, is now led to by the first through hole 221 of valve block 22 corresponding to air-flow
The state in road switches to the second through hole 222 of valve block to correspond to gas channel.
As shown in figure 4, at the another aspect of the utility model embodiment, a kind of cryogenic freezing unit is additionally provided, this is low
