Abstract
The utility model provides a frameless weld joint vacuum leakage checking box, which comprises a transparent plate. A sponge sealing ring made of a sealing sponge is mounted on the periphery of the bottom of the transparent plate, a first through hole and a second through hole are arranged on the transparent plate, the first through hole is communicated with an inlet end of a three-way valve, and the second through hole is communicated with a joint of a vacuum meter. Inner threads are arranged on walls of the first through hole and the second through hole, a first screw tube is mounted in the first through hole, a second screw tube is mounted in the second through hole, the first screw tube is communicated with the inlet end of the three-way valve, and the second screw tube is communicated with the joint of the vacuum meter. A first nut and a second nut are respectively mounted on the first screw tube on the two sides of the transparent plate, and a third nut and a fourth nut are respectively mounted on the second screw tube on the two sides of the transparent plate. The frameless weld joint vacuum leakage checking box has the advantages that vacuumizing time can be shortened, air tightness detecting efficiency of weld joints is improved effectively, the three-way valve 5 and a vacuum pump 6 are detached and replaced conveniently, and cannot loose when used, and the like.
Description
Technical field
The utility model relates to a kind of welding line detector, specifically a kind of frameless formula weld seam vacuum leak test case.
Background technology
Mainly adopting the method that vacuumizes detection, the main part of existing vacuum leakage testing device when butt welded seam carries out airtight test at present all is the cover bodies that have a bottom surface to open wide, when the butt welded seam airtight test; Smear suds in the commissure; Cover body is buckled in the commissure that needs detection, and seals with sealing sponge or clay, then to vacuumizing in the cover body in edge, cover body bottom surface; After vacuum tightness meets the demands, observe this place's weld seam through the transparent windows on the cover body and whether leak gas.Because existing cover body inner space is bigger, the pumpdown time is longer, causes the bubble-tight detection efficiency of present butt welded seam lower.
The utility model content
The purpose of the utility model provides a kind of frameless formula weld seam vacuum leak test case, and it can reduce the pumpdown time, effectively improves weld joint air-tight property detection efficiency.
The utility model is for realizing above-mentioned purpose; Realize through following technical scheme: comprise transparent panel; The sponge sealing ring of being processed by the sealing sponge is installed in border, transparent panel bottom surface; Offer first through hole and second through hole on the transparent panel, first through hole communicates with the entrance point of T-valve, and second through hole is communicated with the joint of vacuum meter.Be equipped with internal thread on the hole wall of said first through hole and second through hole, first screwed pipe is installed in first through hole, second screwed pipe is installed in second through hole, first screwed pipe communicates with the entrance point of T-valve, and second screwed pipe is communicated with the joint of vacuum meter.First nut and second nut are installed respectively on first screwed pipe of transparent panel both sides, the 3rd nut and the 4th nut are installed respectively on second screwed pipe of transparent panel both sides.
The advantage of the utility model is: can reduce the pumpdown time, effectively improve weld joint air-tight property detection efficiency; T-valve 5 and vacuum pump 6 convenient disassemblies are convenient to change, and can not become flexible during use etc.

Embodiment
The described frameless formula weld seam vacuum leak test case of the utility model comprises transparent panel 1; The sponge sealing ring of being processed by the sealing sponge 2 is installed in border, transparent panel 1 bottom surface; Offer first through hole 3 and second through hole 4 on the transparent panel 1; First through hole 1 communicates with the entrance point of T-valve 5, and second through hole 4 is communicated with the joint of vacuum meter 6.During use; Detect bubble-tight commissure at need and smear suds, transparent panel 1 is placed this commissure, the sealing sponge and the transparent panel 1 of border, transparent panel 1 bottom surface surround a sealing area in the commissure; An endpiece of T-valve 5 is connected with vacuum pipe; And T-valve 5 switched to the state that this endpiece communicates with entrance point, extract the gas in the sealing area out, when the reading of vacuum meter 6 arrives required value; Represent that promptly the vacuum tightness in this zone meets the demands, can observe this weld seam through transparent panel 1 this moment and whether leak gas.After detection finishes, T-valve 5 is switched to the state that another endpiece communicates with entrance point, make ambient atmos get into sealing area, make this zone internal and external pressure balance, transparent panel 1 and sponge sealing ring 2 can be removed.The utility model has saved the part of the border of existing leakage testing device cover body; The transparent panel 1 that only keeps the top; And surround sealing area through sponge sealing ring 2 and transparent panel 1; Compare with the sealing area that existing leakage testing device cover body surrounds, significantly dwindled the inner space, the utility model has been shortened more than 70% the existing leakage testing device of time that sealing area vacuumizes; By weld seam is 1000 meters calculating, and the utility model is accomplished the impermeability detection to this weld seam only needs 1 day time.
The utility model is for the ease of dismounting T-valve 5 and vacuum pump 6; Can adopt following structure: be equipped with internal thread on the hole wall of said first through hole 3 and second through hole 4; In first through hole 3 first screwed pipe 7 is installed; In second through hole 4 second screwed pipe, 8, the first screwed pipes 7 are installed and are communicated with the entrance point of T-valve 5, second screwed pipe 8 is communicated with the joint of vacuum meter 6.When need changing T-valve 5 or vacuum pump 6, screwed pipe screwed out to change in the through hole get final product.
The utility model is loosening with vacuum pump 6 in order to prevent T-valve 5, can first nut 9 and second nut 10 be installed respectively on first screwed pipe 7 of transparent panel 1 both sides, and the 3rd nut 11 and the 4th nut 12 are installed respectively on second screwed pipe 8 of transparent panel 1 both sides.First nut 9, second nut 10, the 3rd nut 11 and the 4th nut 12 can be in transparent panel 1 both sides with firm fixing of first screwed pipe 7 and second screwed pipe 8, prevent that T-valve 5 is loosening with vacuum pump 6.
