Abstract
The utility model relates to a combinatory clamp for exhaust and inflation, which comprises a valve body, air suction joint, a pressing sleeve, a compression spring, a valve rod, a switch sleeve, a switch rod, a locknut, a packing gland and inflation joint. The valve body is a columned machined part that is made from stainless steel and a hole is perforated from up to down in the center of the valve body, while a same conical surface for sealing and an annular seal groove are all arranged on the valve body and at one side of the valve body and the air suction joint and the inflation joint and the connecting piece are welded at the other side of the valve body and an inner hole and the locknut are arranged at the lower part of the valve body for clamping the packing gland of the bulb exhaust pipe. In addition, a seal disk is arranged on top of the valve body and is molded with the valve body into one entity through the skeleton bolt and seal head is completely sealed with the conical surface of the valve body orifice, while the outside of the seal disk is sleeved with a valve sleeve and bolts are fixed around the valve sleeve and at the same time the top of the seal disk is connected with the valve rod and can move up and down along the valve rod. The utility model is suitable to multiple varieties and has a high vacuity and a good stability, which can be applied in the multi-stage semi-automatic or full-automatic round air exhauster.
Description
Technical field
The utility model relates to a kind of row, inflation built-up jig, belongs to all kinds of illuminations, decoration, heating lamp kind production special equipment vitals.
Background technology
Since the nineties in last century, electric light source products in China from being close to producer with original means production ordinary incandescent lamp, progressively expand to the production of many kinds and multiple specific use bulb, its development trend, no matter be the crowd of working colony or scale mostly be out of unusual.As everyone knows, the core of any light source product---bulb or fluorescent tube, all be to adopt vacuumizing and exhausting and inflation to reach desirable light efficiency and life-span, but, as long as step a step to mechanization a little, just must have a kind of can vacuumizing and inflate, be convenient to the built-up jig of clamping sealing again, this built-up jig both can be used for manual unit, also can be used on the high large-scale air exhauster of bull and mechanization degree.The valve body formula was progressively developed into afterwards from the most original pressure-pipe type in its predecessor, but all because the limitation of structure is difficult to satisfy the high requirement that pumping high vacuum is especially stablized conservation rate.Built-up jig in the past particularly, the seal point of evacuation passageway and filling channel all has 5～6 places, and every many seal points just mean the hidden danger that leak at many places, and this has just reduced the quality and the service life of lamp, and grind again after all necessary fine finishining in sealing surface small-bore, difficulty of processing is big.
Summary of the invention
Purpose of the present invention just provides a kind of good seal performance, and difficulty of processing is low, can effectively improve row, the inflation built-up jig of a kind of vacuum of product.
The technical solution of the utility model realizes that by following approach it contains valve body, air extraction connector, gland, compression spring, valve rod, switch cover, switch lever, locking nut, sealing shroud and gas-charging connection; Wherein valve body is the cylindrical workpiece that stainless steel is made, valve body central authorities connect a hole from top to bottom, a top and side of valve body all is provided with identical sealing and uses the conical surface with annular seal groove, the another side is welded with air extraction connector and gas-charging connection and connector thereof, the lower end is provided with the endoporus and the locking nut of the sealing shroud that clamping bulb blast pipe is installed, in addition, the top of valve body also is provided with seal disc, it is molded into one by skeleton screw and seal disc, seal header joints and the complete driving fit of valve body hole prostomum face, the outside of seal disc is with valve pocket, is fixed with screw around the valve pocket, the top of seal disc is connected with valve rod again simultaneously, and can move up and down with valve rod.
The utlity model has the characteristics that adapt to many kinds, high vacuum, good stability, satisfy high yield, of fine quality, the requirement of large-scale production of product, can be widely used on the semi-automatic or automatically round air exhauster of several multistation, it vacuumizes actual value and brings up to 5 * 10-2Pa by the highest 5 * 10-1Pa originally and (refer under the current intelligence, can reach 5 * 10-3Pa) when static, retention time after shutoff is bled, as seen its effect was significant from rising to more than 30 seconds less than 10 seconds originally.

Fig. 3 is the scheme of installation of seal disc
Wherein: valve body 1, air extraction connector 2, gland 3, seal disc 4, compression spring 5, valve rod 6, switch cover 7, skeleton screw 9, switch lever 10, screw 11, locking nut 20, sealing shroud 22, gas-charging connection 25
The specific embodiment
The technical solution of the utility model realizes by following approach, taking out one with one, to fill be example (as shown in Figure 1), and it contains valve body 1, air extraction connector 2, gland 3, compression spring 5, valve rod 6, switch cover 7, switch lever 10, locking nut 20, sealing shroud 22 and gas-charging connection 25; Wherein valve body 1 is the cylindrical workpiece of stainless steel making, valve body central authorities connect a hole from top to bottom, a top and side of valve body 1 all is provided with identical sealing and uses the conical surface with annular seal groove, the another side is welded with air extraction connector 2 and gas-charging connection 25 and connector thereof, the lower end is provided with the endoporus and the locking nut 20 of the sealing shroud 22 that clamping bulb blast pipe is installed, in addition, the top of valve body 1 also is provided with seal disc 4, it is molded into one by skeleton screw 9 and seal disc 4, seal header joints and the complete driving fit of valve body hole prostomum face, the outside of seal disc 4 is with valve pocket, be fixed with screw 11 around the valve pocket its periphery is compressed driving fit downwards, the top of seal disc 4 is connected with valve rod 6 again simultaneously, and can move up and down with valve rod 6.The tension force of compression spring 5 can push seal header joints downwards all the time, with valve body 1 aperture conical surface driving fit, reach the effect of turn-offing bleed-off passage, when giving an external force valve rod 6 upwards drawn, seal header joints is left valve body 1 conical surface, also just reach the effect of day opening bleed-off passage, it is characterised in that all issuable leakages is concentrated on around the seal header joints in the close cavity that this also brings great convenience early for undoubtedly the processing of part.
Seal disc 4 can overlap 7 respectively through the automatic Robot actions of controlling by switch lever 10 and switch, open it or close, when it is opened, can start by the vavuum pump that air extraction connector 2 connects bulb is vacuumized, when it is closed, just cut off bleed-off passage, stopped bleeding to bulb, bleed and get rid of the interior air of bulb and other gas, the effect of steam, impurity; In addition; it is undertaking the effect that charges into gas in addition; i.e. flushing midway; light and remove waste gas impurity and must charge into inertia or protective gas; this passage except that a kind of be to utilize above-mentioned vacuumizing the approach; another passage is vertical with the main channel; promptly link up with gas-charging connection 25; sealing means still utilizes sealing as seal disc 4 with the main channel; just can carry out under this situation of only closing in the main channel; otherwise any gas that charges into all can be taken away, so to locate be normally closed, and drawing back in the time will charging into gas by the automatic short time of drag hook; automatically close the same a whole set of anchor clamps of influence of sealing quality herein and the sealing of system then.
The utility model also can adopt one to take out two structures of filling.
