Abstract
A vacuumizing and plugging device with a sealing plug comprises a cylindrical barrel and a push-pull rod component; the cylindrical barrel is provided with a vacuum pumping hole; a central through hole is formed in a seal cover end of the cylindrical barrel; two sealing rings a are arranged at an opening end of the cylindrical barrel; the opening end of the cylindrical barrel is hermetically connected with a component vacuumizing pipe in a plug-in manner; an inner hole of the component vacuumizing pipe is a conical inner hole; the push-pull rod component comprises a push-pull rod, the sealing plug and a hand wheel; the push-pull rod is connected with the central through hole in the seal cover end of the cylindrical barrel in a sealing and sliding manner, and provided with two sealing rings b; the push-pull rod is positioned at one end of the inner cavity of the cylindrical barrel and connected with the sealing plug through threads; the hand wheel is arranged at one end of the outer part of the cylindrical barrel; the sealing plug adopts a cone structure; two sealing rings c are arranged on the conical surface of the sealing plug; the sealing plug is matched and hermetically connected with the conical inner hole of the component vacuumizing pipe, and sealed through the two sealing rings c. The vacuumizing and plugging device has the advantages of compact structure, sealing reliability, convenience in use and low cost, and is especially suitable for occasions where components need to be repeatedly vacuumized.
Description
(1) technical field
The utility model relates to the blocking device after a kind of vacuum drawn, particularly a kind of blocking device that vacuumizes with sealing plug.
(2) background technique
At present, the mode of carrying out shutoff after parts vacuumize has multiple, and the method conventionally adopting is: valve shutoff, thermal distortion shutoff, plug are stifled etc., and its core is all after parts extracting vacuum, to be isolated from the outside.The mode of this shutoff has following shortcoming: valve shutoff cost is high, and thermal distortion shutoff cannot recover, the stifled inconvenient subsequent detection of plug.
(3) model utility content
The purpose of this utility model is for above-mentioned existing problems, a kind of compact structure is provided, seals the blocking device that vacuumizes with sealing plug reliable, easy to use, with low cost.
The technical solution of the utility model:
A kind of blocking device that vacuumizes with sealing plug, formed by cylindrical tube and push-pull rod component, cylindrical tube is provided with vacuum pumping opening, the capping end of cylindrical tube is provided with central through bore, the opening end of cylindrical tube is connected with parts vacuum-pumping tube insertion sealed and is provided with two seals circle a, and parts vacuum-pumping tube endoporus is tapered bore; Push-pull rod component comprises pull bar, sealing plug and handwheel, the central through bore sealed sliding of pull bar and cylindrical tube capping end is dynamically connected and is provided with two seals circle b, one end that pull bar is positioned at cylindrical tube intracoelomic cavity is connected with sealing plug by screw thread, the one end that is positioned at cylindrical tube external body is provided with handwheel, sealing plug is conical structure, the sealing plug conical surface is provided with two seal grooves and two seals circle c, and sealing plug mates the two seals circle c being tightly connected and pass through in seal groove and seals with the tapered bore of parts vacuum-pumping tube.
The utility model has the advantages that: this vacuumizes blocking device compact structure, it is reliable, easy to use, with low cost to seal, be specially adapted to parts and need repeat the occasion of extracting vacuum.

(5) embodiment
A kind of blocking device that vacuumizes with sealing plug, formed by cylindrical tube 1 and push-pull rod component, cylindrical tube 1 is provided with vacuum pumping opening 2, the capping end of cylindrical tube 1 is provided with central through bore, the opening end of cylindrical tube 1 is connected with parts vacuum-pumping tube 3 insertion sealeds and is provided with two seals circle a4, and parts vacuum-pumping tube 3 endoporus are tapered bore, push-pull rod component comprises pull bar 5, sealing plug 6 and handwheel 7, pull bar 5 is dynamically connected and is provided with two seals circle b8 with the central through bore sealed sliding of cylindrical tube 1 capping end, one end that pull bar 5 is positioned at cylindrical tube 1 inner chamber is connected with sealing plug 6 by screw thread, the one end that is positioned at cylindrical tube 1 outside is provided with handwheel 7, sealing plug 6 is conical structure, the sealing plug conical surface is provided with two seal grooves and two seals circle c two seals circle c9, sealing plug 6 mates the two seals circle c9 being tightly connected and pass through in seal groove and seals with the tapered bore of parts vacuum-pumping tube 3.
Before using, push-pull rod component and cylindrical tube are assembled.When use, in sealing plug puts seal ring c receiving member vacuum-pumping tube, vacuumize by vacuum pumping opening.In the time that degree of vacuum reaches requirement, by lower push-pull bar, utilize the negative pressure in parts, sealing plug is inhaled firmly in parts vacuum-pumping tube.In the time that needs repeat to vacuumize, rotation hand wheel, mentions pull bar and can carry out work.Applicable scope of the present utility model is: degree of vacuum is higher than 1x10
-6pa vacuumizes shutoff.Practice shows: effect is good.
