position 105 has made The cooperation seal line of sealing function is relatively reliable, and the first spool 106 is stuck at sealing aperture, and the second air inlet pipeline 103 is sealed, 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 Cylinder 301 air inlets work.At the same time, due to the inside decompression of the second drying cylinder 302, the second regeneration pipeline 216 of regeneration valve is led Logical, a part of dry gas flows to the second drying cylinder 302 from the second regeneration pipeline 216, flows through the second drying cylinder from top to bottom 302 inside, realizes the dry regeneration of the desiccant of the inside of the second drying cylinder 302, and from the of 302 bottom of the second drying cylinder The discharge of two discharge pipes 110 can be arranged muffler in the second discharge pipe 110, eliminate noise；Similarly, first drying cylinder 301 First solenoid valve 107 of control discharge is powered when opening, it can be achieved that the work of the second drying cylinder 302, the regeneration of the first drying cylinder 301 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 It

respectively equipped with third spool 205 and the 4th spool 206, since its gravity is respectively placed in third The infundibulate lower end of valve position 211 and the 4th valve position 212, forms third outlet pipe 202 and the 4th outlet pipe 203 closes shape State.When the second drying cylinder 302 is in gaseity, third spool 205 above 301 outlet pipe of the first drying cylinder due to Gravity drops down at third circular conical surface, and since gas circuit aperture is less than 205 diameter of third spool, third spool 205 is stuck in sealing At circular conical surface, third outlet pipe 202 is closed, the air-flow that the second drying cylinder 302 comes out will blow the 4th spool 206 Open the 4th outlet pipe 203, air-flow enters in outlet Correspondent pipe 210, finally by the main escape pipe road 204 of air outlet valve 200 Flow out air outlet valve 200；Similarly, when the first drying cylinder 301 is in gaseity, above 302 outlet pipe of the second drying cylinder 4th spool 206 is dropped down at the 4th circular conical surface due to gravity, since gas circuit aperture is less than 206 diameter of the 4th spool, the 4th Spool 206 is stuck at sealing circular conical surface, and the 4th outlet pipe 203 is closed, and the air-flow that the first drying cylinder 301 comes out will Blowing third spool 205 opens third outlet pipe 202, and air-flow enters in the outlet Correspondent pipe 210 of drying device, finally Air outlet valve 200 is flowed out by the main escape pipe road 204 of air outlet valve 200.As shown in figure 8, the embodiment
