Abstract

The utility model discloses a pipe fitting welding seam detection device, a serial communication port, does frame lower extreme around the recess paste that to have flexible, thickness be 0.5cm including the inboard shaping notched arch piece of lower extreme 1cm's rubber frame, it corresponds the concave groove holes size to survey the hole size in the rubber frame, the recess intermediate position sets up a through -hole, and through -hole upper end shaping has piston tube, set up in the piston tube and be used for the piston of bleeding. Compared with the prior art, the utility model discloses though simple structure still has fine beneficial effect: set up flexible rubber frame, make its easy abundant contact in the pipe fitting surface with the unevenness to it is good to make the recess leakproofness, arch piece, piston tube and piston adopt transparent material, are favorable to observing, draw the piston outward to pressure reduces in making the recess, and it is extremely convenient to operate.

Description

A kind of tube element welding seam checkout gear

Technical field

The utility model relates to detecting class, is specifically related to a kind of device for detecting gap.

Background technology

Industrially, after the welding of various pipe fittings is good, utilizes air pump to produce gases at high pressure, be transported in pipeline, then in weldering Connect place's watering, detected whether aperture or gap, the most not only increased electric cost and also add cost of labor；If Do not weld, have gap, weld the most defective, do over again；The pipeline at place pinnacled, inconvenient is done over again, the most cumbersome. There is presently no limit weld-end fittings, frontier inspection surveys the instrument of weld seam.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of tube element welding seam checkout gear.

For realizing the purpose of the utility model, it is achieved by the following technical solutions: a kind of tube element welding seam checkout gear, It is characterized in that, being molded reeded arch sheet including lower end inside, the frame lower end of groove vicinity is pasted with flexibility, thickness Rubber frame for 0.5cm-1cm；Gaging hole size respective slot mouth size in rubber frame；Groove centre position arranges a through hole, Through hole upper end forms piston tube；The piston bled it is provided in piston tube.

Preferably, described arch sheet, piston tube and piston all use transparent material.

Preferably, two arcuate borders before and after described groove stretch out 0.5cm-2cm.

Preferably, the big 0.5cm-1cm of border width of the width ratio groove vicinity on the limit of described rubber frame.

In arch sheet lower end sticking flexible rubber frame, arch sheet, downwardly against rubber frame, utilizes the softness of flexible rubber frame Property be fully contacted with irregular tube surface, and then reach groove and outside air and isolate.When being pulled outwardly piston, make groove Internal gas pressure reduces, if there being gap at pipe fitting welding, outside air will enter groove；If weld has water, arise that Bubble.

Compared with prior art, although the utility model simple in construction still has good beneficial effect: arrange soft Property rubber frame so that it is be easily fully contacted with irregular tube surface, so that groove good airproof performance；Arch sheet, piston tube Use transparent material with piston, facilitate look at；Drawing outward piston, so that pressure reduces in groove, it is the most convenient to operate.

Detailed description of the invention

Below according to accompanying drawing 1-4, a detailed description of the invention of the present utility model is made a detailed explanation.

A kind of tube element welding seam checkout gear, it is characterised in that include that lower end inside is molded reeded arch sheet 2, groove Frame lower end around be pasted with flexibility, thickness be the rubber frame 1 of 0.5cm-1cm；Gaging hole size respective slot in rubber frame 1 Mouth size；Groove centre position arranges a through hole, and through hole upper end forms piston tube 3；It is provided in piston tube 3 bleeding Piston 4.

Preferably, described arch sheet 2, piston tube 3 and piston 4 all use transparent material.

Preferably, the big 0.5cm-1cm of border width of the width ratio groove vicinity on the limit of described rubber frame 1.

Arch sheet 2 and piston tube 3 can use injection moulding integrated molding.

Using method: 1, need at the pipe fitting welding of detection and around wherein one side clean up as far as possible, smooth, spill Upper water；

2, left hand pinches piston tube, pipe fitting welding lines circumferentially is covered in groove, firmly makes rubber frame It is close on pipe fitting, makes this device groove separate with outside air；

3, right handgrip piston pulls out outside piston tube, and observes whether weld has bubble to produce simultaneously；

If 4 have observed bubble, then explanation has aperture or gap.

Claims

1. a tube element welding seam checkout gear, it is characterised in that include that lower end inside is molded reeded arch sheet, groove vicinity Frame lower end be pasted with flexibility, thickness be the rubber frame of 0.5cm-1cm；In rubber frame, gaging hole size respective slot mouth is big Little；Groove centre position arranges a through hole, and through hole upper end forms piston tube；The piston bled it is provided in piston tube.
