Firmly, the compressed gas that main air inlet pipe road 101 flows into enters the first drying cylinder 301 via the first air inlet pipeline 102, realizes that first is dry
Dry 301 air inlet of cylinder work.At the same time, due to the inside decompression of the second drying cylinder 302, the second regeneration pipeline 216 of regeneration valve
Conducting, a part of dry gas flow to the second drying cylinder 302 from the second regeneration pipeline 216, and it is dry to flow through second from top to bottom
The inside of cylinder 302, realizes the dry regeneration of the desiccant of the inside of the second drying cylinder 302, and from 302 bottom of the second drying cylinder
The discharge of second discharge pipe 110 can be arranged muffler in the second discharge pipe 110, eliminate noise；Similarly, the first drying cylinder 301
Control discharge the first solenoid valve 107 be powered open when, it can be achieved that the second drying cylinder 302 work, the first drying cylinder 301 again
Raw process.
Pipeline where first spool 106 between two intake valve positions is set as horizontal pipeline so that the first spool 106 by
Air-flow is poor and moves without resistance, more accurate to the control in air inlet period.As shown in fig. 6, the embodiment of intake valve 100
The pipeline shape of one: the first valve position 104 and the second valve position 105 be it is round table-like, the first spool 106 be ball；As shown in figure 13, into
Two: the first valve position 104 of embodiment of air valve 100 and the pipeline shape of the second valve position 105 are billiard table shape, and the first spool 106 is bottom
The double cone that portion connects；As shown in figure 14, the pipeline of embodiment three: the first valve position 104 and the second valve position 105 of intake valve 100
Shape is billiard table shape, and the first spool 106 is ball；As shown in figure 15, the example IV of intake valve 100: the first valve position 104 and
The pipeline shape of two valve positions 105 is billiard table shape, and the first spool 106 is the double cone of bottom connection.
The inlet end of air outlet valve 200 is equipped with third outlet pipe 202 and the 4th outlet pipe 203, third outlet pipe 202
It is respectively equipped with third valve position 211 and the 4th valve position 212 with the 4th outlet pipe 203, third valve position 211 and the 4th valve position 212 are divided
Not She You third spool 205 and the 4th spool 206, third outlet pipe 202 is connected to main escape pipe road with the 4th outlet pipe 203
204, third outlet pipe 202 is connected to the top of the first drying cylinder 301, and the 4th outlet pipe 203 is connected to the second drying cylinder 302
Top, set third spool 205 in third valve position 211, the 4th spool 206, the pipe of two air outlet valve positions set in the 4th valve position 212
Road is up big and down small funnel-form or billiard table shape, and the major diameter of two air outlet valve positions is towards outlet side, two air outlet valve positions
Path be respectively facing inlet end, third spool 205 and the 4th spool 206 are ball perhaps bottom-up rotary table or bottom
The circular cone of portion upward, two air outlet valve position lower openings diameters are less than the maximum gauge for being respectively smaller than respective outlet spool.When
First drying cylinder 301 is in gaseity, sealing circle of the 4th spool 206 due to dropping to the 4th valve position under the action of self gravity
At the conical surface, the 4th outlet pipe 203 is closed in sealing, and the air-flow of the first drying cylinder 301 pushes up the third spool 205 of the side upwards

106 row of core is to the first valve position 104, maximum gauge due to the path of its gas circuit less than the first spool 106, the first spool 106 card
At sealing circular conical surface, the first air inlet pipeline 102 is sealed, the compressed gas that main air inlet pipe road 101 flows into is via the second valve position
105 pipeline enters the first air inlet pipeline 103, realizes 302 air inlet of the second drying cylinder work；Second drying cylinder 302 is in outlet
State, the third spool 205 above 301 outlet pipe of the first drying cylinder drop down onto the bottom of third valve position 211 due to gravity
Portion, since gas circuit aperture is less than the maximum gauge of third spool 205, third spool 205 is stuck at sealing circular conical surface, third is gone out
Air pipe 202 is closed, and the air-flow that the second drying cylinder 302 comes out, which will blow the 4th spool 206, makes the 4th outlet pipe 203
It opens, air-flow enters in outlet Correspondent pipe 210, finally flows out air outlet valve 200 by the main escape pipe road 204 of air outlet valve 200；When
So, a part of dry gas can be drawn by the first regeneration pipeline 215 and removes the first drying cylinder 301, so that the first drying cylinder 301
Desiccant is able to pulse cleaning.
2 above-mentioned stages are the movements of a cycle of the utility model, repeat the actuation cycle in the period, this is practical
The air inlet of novel realization the first drying cylinder 301 and the second drying cylinder 302 switches.As for period length, can be set as needed, than
If the period is set as 10 minutes, stage 1 and stage 2 are respectively every 5 minutes.
Above embodiments are not limited to the technical solution of the embodiment itself, can be incorporated between embodiment new
Embodiment.Above embodiments are only to illustrate the technical solution of the utility model and are not intended to limit it, all without departing from this
Any modification of utility model spirit and scope or equivalent replacement should all cover the range in technical solutions of the utility model
It is interior.
