Above-mentioned intake valve, its complex structure, number of parts is many, processing, assembling difficulty.In addition, above-mentioned intake valve, because it acts frequently, seal washer 5 and packing ring 19 are easily damaged parts, need to often change, and the structure of intake valve are changed seal washer 5 and packing ring 19 needs the part of dismounting more, are unfavorable for that the fault of intake valve is got rid of and maintenance.Meanwhile, above-mentioned intake valve, because it acts frequently, spring 12 is always in alternation state, and spring is limited 12 working lifes, thus the working life of having limited intake valve.
Summary of the invention
The difficulty of bringing because changing easily damaged parts for solving existing intake valve, and the physical life of prolongation intake valve, the object of this invention is to provide a kind of novel intake valve and using method thereof simple in structure, reasonable in design, it can make the number of parts of intake valve few, processing, assembling are simply, the replacing of easily damaged parts is quick and easy, and the working life of intake valve is longer.
For achieving the above object, the present invention adopts following technological scheme:
A novel intake valve, it mainly comprises connection plug screw, seal washer, bolt, plain washer, lower valve body, O-ring seals, upper valve body, spool and packing ring.Connect plug screw and play installation anastomosis, and on it, be processed with liquid inlet; On lower valve body, be processed with vacuum gauge interface and liquid outlet; On upper valve body, be processed with two gas connection mouths.
Described novel intake valve, it connects plug screw, lower valve body and upper valve body and by scyewed joint duplicate invoice, is connected into the valve body of intake valve.
Described novel intake valve, is processed with three piston rings on its spool, work intake valve is divided into enterprising air cavity, lower air-inlet cavity, liquid discharge oral cavity and chamber, liquid inlet with valve body one.An O-ring seals is housed on spool upper piston ring separates upper and lower air-inlet cavity; Two O-ring seals are housed on piston ring in spool separates lower air-inlet cavity and liquid discharge oral cavity; On spool lower piston ring, by bolt and plain washer, a seal washer is housed, liquid discharge oral cavity and chamber, liquid inlet is separated and play the crashproof effect of damping.
Described novel intake valve, the packing ring that adopts teflon to process is equipped with in its upper valve body end, plays the crashproof effect of damping.
The using method of described novel intake valve, during the logical pressurized air of its enterprising air cavity, spool is adjacent to connection plug screw, and intake valve cuts out; During the logical pressurized air of its lower air-inlet cavity, move away connection plug screw on spool, intake valve is opened.
Owing to adopting technological scheme as above, the present invention has following superiority:
This novel intake valve, it is simple in structure, reasonable in design.Due to this intake valve to close and open be all that the active force producing by pressurized air operates, cancelled the spring in original structure, so the working life of intake valve is longer; In addition, its number of parts is less, and processing, assembling simply, while changing easily damaged parts, need the part of dismounting few, and the fault that is conducive to intake valve is got rid of and maintenance.
