Background technique:
At present, what heat-preserving equipment vacuumized that operation generally adopts is a kind of vacuum valve, exhaust vacuum after this valve be retained in so a kind of mode on equipment.In use there is following shortcoming in which: on (1) valve, sealing surface is more, in other words be that easy leak source is more, and valve internal channel is less, and has labyrinth, multiple 90 ° of right angles, losing along stroke pressure while having increased circulation of air, causes the pumpdown time longer; (2) vacuum valve is retained on equipment, in handling, installation and using process, exist easily by clashing and breaking and sealing face leakage, thus the danger of destruction vacuum; (3) every equipment is installed a vacuum valve and the long increase that has caused cost of production of pumpdown time.
Model utility content:
The purpose of this utility model is to provide a kind of ultrahigh vacuum valve door device, and it adopts hermetically sealed technology, thereby has improved degree of vacuum; It is a kind of mode of structure of straight-through type; When vacuumizing after end, it can, under vaccum working condition, realize the sealing to vacuum orifice by operating device; Thereby realize, condition of high vacuum degree, shorter manufacture cycle, lower cost of production, using process are safe and reliable, the object of high quality of products.
In order to solve the existing problem of background technique, the utility model is to adopt following technological scheme: it comprises valve body 1, spool 2, operating handle 3, seal 4, pin 5, support 6, bellows 7, flap 8, O-ring seals 9, take over 10, union nut 11, equipment takes over 12, flap 8 is threaded with spool 2 and is arranged in valve body 1, operating handle 3 inserts in the square hole of spool 2 by valve body 1 side, and be fixed on support 6 by pin 5, seal 4 is by operating handle 3, support 6 is welded on valve body 1, bellows 7 is through operating handle 3, one end is welded on seal 4, the other end is welded on operating handle 3, equipment is taken over 12 and is welded on the equipment of being evacuated, O-ring seals 9 is arranged on valve body 1 lower end and takes over 10 junctions, union nut 11 is threaded with valve body 1 by taking over 10, take over 10 and take over 12 through equipment, by adjusting union nut 11, ultrahigh vacuum valve is fixed in equipment adapter 12.
Described valve body 1 left side is provided with the quick connection mouth with vaccum-pumping equipment.
All parts (except O RunddichtringO) of described ultrahigh vacuum valve all adopt stainless steel material manufacture.
Described ultrahigh vacuum valve adopts hermetically sealed bypass structure.
Working principle of the present utility model is: in the time that need vacuumize, this device is inserted in to equipment and takes over 12, by adjusting the degree of tightness of union nut 11, realize the sealing of O-ring seals 9 to equipment adapter place.Fast interface on valve body 1 is connected with vaccum-pumping equipment, to pressing down, makes flap 8 in working hole top operating handle 3, then start vacuum pumping.In the time that degree of vacuum reaches regulation requirement, close vaccum-pumping equipment, operating handle 3 is upwards lifted, operating handle 3 is with movable valve plug 2 to move down, and flap 8 is sent into equipment and take over the sealing station in 12.Solution format device is connected with vaccum-pumping equipment, unclamps union nut, and valve body 1 is moved up and takes over 12 with equipment to be separated, and in the sealed mouth that at this moment spool 2 and flap 8 are taken in equipment, by flap 8 compactings, rotary spool 2, makes it to depart from flap 8.
The utlity model has following beneficial effect: adopt hermetically sealed technology, thereby improved degree of vacuum; It is a kind of mode of structure of straight-through type; When vacuumizing after end, it can, under vaccum working condition, realize the sealing to vacuum orifice by operating device; Thereby realize, condition of high vacuum degree, shorter manufacture cycle, lower cost of production, using process are safe and reliable, the object of high quality of products.
