Abstract
The utility model discloses a vacuumizing tooling which can shorten the trip of a plug push rod, i.e. the trip of a vacuum plug so as to allow the vacuum plug to quickly plug a vacuum pipe seat. The vacuumizing tooling comprises a plug push rod, an evacuating sleeve and an evacuating pipe arranged at the side of the evacuating sleeve, wherein the orifice of the evacuating pipe is communicated with the inner cavity of the evacuating sleeve, and a top plug is arranged at the top of the evacuating sleeve; a through hole matched with the plug push rod is arranged in the top plug, and the plug push rod extends into the inner cavity of the evacuating sleeve through the through hole of a top cover; connecting external threads are arranged at the end part of the plug push rod, and a side seal is arranged between the plug push rod and the inner cavity wall of the evacuating sleeve; and the evacuating pipe is obliquely arranged to form a Y-shaped structure with the evacuating sleeve. The utility model greatly shortens the time that the vacuum plug plugs the vacuum pipe seat, so that the degree of vacuum in steel cylinders is well ensured.
Description
Technical field
The utility model relates to vacuum pumping tool equipment.
Background technique
As shown in Figure 1, originally the vacuum pumping tool equipment of Shi Yonging in order to allow evacuation tube 3 can dodge the facility that is arranged on steel cylinder 1 top, will be taken out pipe box 2 usually and do very longly, adapt therewith, and the plug push rod 4 that is used to push the vacuum plug is also longer.Its working procedure is: the screw thread by plug push rod 4 ends is connected with the vacuum plug, by the time after being pumped into vacuum in the steel cylinder 1, by plug push rod 4 pushing vacuum plugs, make it block the vacuum tube base that is arranged in vacuum plug below, reach the purpose of vacuum shutoff; Then, plug push rod 4 is screwed out from the vacuum plug.But, in actual use, because the vacuum plug is longer at the stroke of finding time in overlapping of vacuum pumping tool equipment, shutoff is rapid inadequately, often cause problems such as vacuum leak, make that the degree of vacuum in the steel cylinder 1 is had a greatly reduced quality, sometimes even can cause vacuum all that has been achieved is spoiled.
The model utility content
A technical problem to be solved in the utility model is: a kind of stroke that shortens the plug push rod is provided is the stroke of vacuum plug, make the vacuum pumping tool equipment of vacuum plug quick blocking vacuum tube base.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: vacuum pumping tool equipment, comprise: the plug push rod, the evacuation tube of finding time to overlap on the side of finding time to overlap and be arranged on, the pore of evacuation tube communicates with the inner chamber of finding time to overlap, the top of finding time to overlap is provided with the top plug, offer the through hole that matches with the plug push rod in the plug of top, described plug push rod stretches into from the through hole of top cover to be found time to overlap in the inner chamber, the end of plug push rod is provided with the connection outside thread, be provided with side seal between the plug push rod and the internal chamber wall of finding time to overlap, described evacuation tube becomes oblique layout, cover forms " Y " shape structure with finding time.
Described side seal comprises at least one seal ring.
The beneficial effects of the utility model are: the utility model by adjust evacuation tube and find time to overlap between angle, make both form " Y " shape structure, both made evacuation tube avoid the facility at steel cylinder top well, the length of finding time to overlap is shortened greatly, so just make that the stroke of plug push rod is that the stroke of vacuum plug shortens greatly, thereby shortened the time of vacuum plug shutoff vacuum tube base greatly, the vacuum shutoff is swift in motion and effectively, makes that the degree of vacuum in the steel cylinder has obtained good guarantee.In addition, also reduced the fabricating cost of whole vacuum pumping tool equipment.

Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 2, vacuum pumping tool equipment described in the utility model, comprise: plug push rod 4, find time to overlap 2 and be arranged on the evacuation tube 3 of finding time to overlap on 2 sides, the pore of evacuation tube 3 with find time to overlap 2 intracavity inter-connection, find time to overlap 2 top and be provided with top plug 6, offering the through hole that matches with plug push rod 4 in the top plug 6---plug push rod 4 can move axially in this through hole, described plug push rod 4 stretches into from the through hole of top cover 5 finds time to overlap in 2 the inner chamber, the top of plug push rod 4 is provided with operating handle 5, the end of plug push rod 4 is provided with the connection outside thread---and this connection outside thread matches with the internal thread that is connected that is arranged on vacuum plug 8 tops, plug push rod 4 and finding time overlaps between 2 the internal chamber wall and is provided with side seal, this side seal mainly is made of two seals circle 7,3 one-tenth oblique layouts of described evacuation tube, with find time to overlap 2 and form " Y " shape structures.As shown in Figure 3, described evacuation tube 3 is connected with vacuum valve 14 in the vaccum-pumping equipment 13 by pipeline.
During practical application, vacuum plug 8 can be overlapped 2 bottom fills in and finds time to overlap 2 from finding time, then plug push rod 4 is screwed in the vacuum plug 8, by lifting plug push rod 4, allow vacuum plug 8 be positioned at the top (not blocking evacuation passage) of evacuation tube 3 pores, then seal ring 12 is enclosed within on the annular boss of vacuum tube base 11, vacuum tube base 11 is overlapped 2 bottom to be filled in and finds time to overlap 2 from finding time, then, be sleeved on the vacuum tube base 11 connecting head 10 by screw thread with find time to overlap 2 and be connected, and make the annular boss of seal ring 12 and vacuum tube base 11 and the tube wall bottom of finding time to overlap 2 form sealing.At this moment, just can open relevant device steel cylinder 1 is vacuumized, when instrument shows, after pressure in the steel cylinder 1 reaches setting value, close relevant device, push plug push rod 4 simultaneously fast, make vacuum plug 8 fast and effeciently carry out shutoff to vacuum tube base 11, vacuum finishes; Then, plug push rod 4 is screwed out from vacuum plug 8, unclamp connecting head 11, make vacuum pumping tool equipment and vacuum tube base 11 break away from.
