Abstract
The invention discloses vacuum pumping tool equipment which can shorten the stroke of a plug push rod, namely the stroke of a vacuum plug so that the vacuum plug rapidly seals a vacuum pipe seat. The vacuum pumping tool equipment comprises a plug push rod, a vacuum pumping sleeve and a vacuum pumping pipe, wherein the vacuum pumping pipe is arranged on the side surface of the vacuum pumping sleeve; a pipe hole of the vacuum pumping pipe is communicated with an inner cavity of the vacuum pumping sleeve; the top of the vacuum pumping sleeve is provided with a top plug; a through hole which is matched with the plug push rod is arranged in the top plug; the plug push rod extends into the inner cavity of the vacuum pumping sleeve from the through hole of a top cover; the end part of the plug push rod is provided with connected external threads; a side seal is arranged between the plug push rod and the inner cavity wall of the vacuum pumping sleeve; and the vacuum pumping pipe is obliquely distributed and forms a Y-shaped structure with the vacuum pumping sleeve. The invention greatly shortens the time for sealing the vacuum pipe seat by the vacuum plug so that the vacuum degree in a steel bottle is favorably ensured.
Description
Technical field
The present invention 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.
Summary of the invention
A technical problem to be solved by this invention 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 used in the present invention 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 invention has the beneficial effects as follows: the present invention 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 invention in detail.
As shown in Figure 2, vacuum pumping tool equipment of the present invention, 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.
