In order to reach the foregoing invention purpose, the technical scheme that the utility model provides is as follows:
A kind of vacuum plant that is used for the detection of the close property of shipbuilding fillet weld, it is characterized in that, this vacuum plant include an equilateral triangle panel, be fixed on seal pad on three limits of panel, be fixed on the cellular rubber on the seal pad and be arranged on two joints on the panel, the angle between described panel and the seal pad is an acute angle.
In vacuum plant of the present utility model, on described panel, also be provided with a handle, this handle is positioned at the middle part of panel top.
In vacuum plant of the present utility model, described first connection tensimeter that connects, another connects snorkel, and two joints all are communicated with the upper surface and the lower surface of panel.
In vacuum plant of the present utility model, described joint is the screwed circular copper billet in middle perforate and upper end, joint is provided with rubber washer and four fixed screws, middle perforate on the joint is alignd with the supporting through hole of panel excavation, and is connected and sealed by rubber washer and fixed screw.
In vacuum plant of the present utility model, described joint is distributed in the both sides of handle.
In vacuum plant of the present utility model, described seal pad is that the xsect that an organic glass is made is trapezoidal sheet material, and the mode by the glue bonding between sealing plate and the cellular rubber connects.
Based on technique scheme, the vacuum plant that is used for the detection of the close property of shipbuilding fillet weld of the present utility model is compared with vacuum plant of the prior art has following technological merit: 1. vacuum checking device of the present utility model can detect the triangle corner that conventional vacuum (-tight) housing can't detect, simple in structure, convenient and practical, reduce road, back workload, improve the efficient of shipbuilding.
2. vacuum checking device of the present utility model can vacuumize the detection of close property by the triangle corner that self-position is regulated different angles.

Fig. 2 is the structural representation of facing of the utility model vacuum plant of being used for the detection of the close property of shipbuilding fillet weld.
Fig. 3 is the partial sectional view that the utility model is used for the vacuum plant of the close property of shipbuilding fillet weld detection, and promptly the A-A among Fig. 1 is to view.
Embodiment
Come the vacuum plant that the utility model is used for the detection of the close property of shipbuilding fillet weld done further below in conjunction with accompanying drawing and specific embodiment and elaborate; in the hope of understanding its structure type and use-pattern more cheer and brightly, but can not limit protection domain of the present utility model with this.
Please see Figure 1 and Fig. 2 earlier, Fig. 1 is the plan structure synoptic diagram that the utility model is used for the vacuum plant of the close property of shipbuilding fillet weld detection, and Fig. 2 is the structural representation of facing of the utility model vacuum plant of being used for the detection of the close property of shipbuilding fillet weld.As seen from the figure, the utility model vacuum plant primary structure of being used for the detection of the close property of shipbuilding fillet weld include an equilateral triangle panel 1, be fixed on seal pad 4 on three limits of panel 1, be fixed on the cellular rubber 5 on the seal pad 4 and be arranged on two joints 3 on the panel 1.
Because this vacuum plant belongs to a seal closure design, need form a cavity at the lower surface of panel 1, the cavity here is to be that acute angle is realized by the angle between panel 1 and the seal pad 4, specifically be that a lateral edges of seal pad 4 and a lateral edges of panel 1 are fixed, the angle of the two is less than 90 degree, and the side that seal pad 4 is not connected with panel 1 is provided with cellular rubber 5, as shown in Figure 3.
Retractable operation is convenient when working for the hand-held sealing device of constructor in putting into practice, and also is provided with a handle 2 on the upper surface of panel 1, and this handle 2 specifically is the middle part that is positioned at panel 1 top.Because the design feature of triangle itself in line with the principle of handled easily, is installed on handle 2 on the leg-of-mutton center line.
The sealing device is if realize vacuumizing, need to connect air pump, so just need change cavity and the external joint that contacts and check the device that space pressure changes in this vacuum lacuna, here just need on panel 1, design two joints, one of them joint 3 connects tensimeter, and another connects snorkel, and this snorkel connects air pump, two joints 3 all are communicated with the upper surface and the lower surface of panel 1, so that carry out vacuum pumping and Pressure monitoring.
In concrete design, described joint 3 is the screwed circular copper billet in middle perforate and upper end.For the ease of being connected with panel 1, joint 3 is provided with four fixed screws, and designed rubber washer at connecting portion, corresponding with the middle perforate on the joint 3, the supporting through hole of excavation on panel 1, by alignment on the joint 3 middle perforate and the supporting through hole on the panel, and the two is connected and sealed by fixed screw and rubber washer.
In order to realize stability, two joints 3 are distributed in the both sides of handle 2, and handle 2 then is installed on a leg-of-mutton center line.
Described panel 1 is a triangular structure, is a simple equilateral triangle plate, and its each edge is cut tiltedly, is convenient to like this be connected with seal pad 4.When seal pad 4 and panel 1 corner connection, stablize for guaranteeing to connect, the seal pad edge exceeds panel upper surface one segment distance.Seal pad 4 is that the xsect that an organic glass is made is trapezoidal sheet material, and the mode by the glue bonding between sealing plate 4 and the cellular rubber 5 connects.
In shipbuilding, the vacuum plant use that the utility model is used for the detection of the close property of fillet weld comprises following step:
When the first step, close property check, treat that vacuum plant is ready to after, to triangle corner weld seam spraying liquid soap, the triangle vacuum plant is covered the corner, move by position own, find correct position to make the corner form seal cavity.
Second step, regulate breather valve, when treating that tensimeter reaches the force value of regulation,, directly detect weld seam and have or not bubble to emerge by torch for illumination, reach the tightness of welding lines testing goal.
In the 3rd step, after finishing, detection closes gas admittance valve.
The 4th step if detect the weld seam defectiveness, repeated above-mentioned three steps after then waiting to repair, if weld seam is intact, then detects and finish.
The utility model can effectively detect the triangle dead angle in the shipbuilding process, fundamentally solve the insurmountable problem of conventional vacuum cover, and the operation reach reduces workload, effectively raises the construction progress of boats and ships.
