Description

Technical Field

[0001] The present invention relates to the technical field of waterproof coiled material detection, and in particular to a coiled material waterproofness detection device. Background Art

[0002] The waterproofness test of waterproof membrane is also called the impermeability test of membrane. When designing waterproof membrane, such as when setting the ratio of asphalt and other components, verifying the impermeability of the waterproof membrane under different ratios has important guiding significance for the adjustment of the ratio. At the same time, the waterproof membrane after production is sampled for impermeability test to ensure the quality of the product, and the process can be adjusted according to the test results.

[0003] At present, when testing the water-tightness of waterproof membranes, the waterproof membranes are cut into rectangular or circular structures, and then a test paper of the same structure is placed on the lower side. Then, water is injected and pressure is applied on the upper side of the waterproof membrane for a period of time to test whether water penetrates through the waterproof membrane to the test paper, thereby causing the test paper to change color, and thus knowing whether the waterproof membrane has a water permeability problem. During the test, it is often necessary to cut a circular structure test piece from the waterproof membrane, and the existing cutting process has the problem of irregularity on the periphery of the test piece, that is, the smoothness of the periphery of the test piece is not convenient to control. The existence of this problem will cause water to penetrate downward from the periphery to the test paper during the water permeability test, thereby affecting the test results. In order to solve this technical problem, a rubber ring is usually set on the periphery of the test piece to avoid water leakage. There is also a ring set between the test paper and the waterproof membrane, and the ring is attached to the test bench by asphalt or other materials, and the test paper is placed in the ring. When the test is carried out, the test piece is pressed and it is tightly attached to the upper wall of the ring, thereby avoiding water leakage to a certain extent, thereby improving the accuracy of the test. However, in actual operation, it is found that the flatness of the upper and lower walls of the waterproof membrane will directly affect the test results. Summary of the invention

[0004] The present invention provides a coiled material waterproofness detection device to solve the above-mentioned deficiencies in the prior art and the problem of water leakage during the waterproof coiled material impermeability detection, and has strong practicality.

[0005] In order to achieve the purpose of the present invention, the following technologies are proposed: A waterproof property detection device for a coiled material comprises a chassis, a sealing member is installed on the chassis, an upper cover is provided on the upper end of the sealing member, a liquid inlet member and an exhaust member are installed on the upper end of the sealing member, a placement member is provided on the chassis, and the placement member is located inside the lower end of the chassis. During detection, the waterproof coiled material is placed in the sealing member and placed on the placement member, and the inner periphery of the sealing member can act on the outer periphery of the waterproof coiled material through the sealing member, thereby ensuring the sealing effect between the outer periphery of the waterproof coiled material and the sealing member to avoid water leakage, thereby improving the sealing effect during detection, and the liquid inlet member facilitates the entry of water, and the exhaust member facilitates the exhaust of the gas inside the sealing member when water is injected into the sealing member. The placement member can stably fix the test paper, and when the waterproof coiled material and the placement member are placed, the position of the test paper can be prevented from moving, thereby achieving the purpose of improving the detection accuracy. When testing with water injected, the space formed by the upper cover, waterproof membrane and seal provides space for water injection operation. In order to facilitate water injection, the water injection pipe connected to the upper cover also has the effect of exhausting air, and a valve is provided on it, which can be closed after the exhaust is completed, so that water can be continuously injected into the test space and maintained at a certain water pressure for a certain period of time.

[0057] In this embodiment, when the installation operation of the seal 2 and the like is being performed: Step 1: The operator places the outer convex edge 234 of the lower end of the rubber ring 226 between the upper extension ring 203 and the inner ring 201.

[0058] In step 2, the operator screws the external thread ring 238 onto the inner circumference of the upper extension ring 203, and screws the lower pressure ring 239 to act on the upper wall of the outer convex edge 234, and finally completes the connection and fixation of the lower end of the rubber ring 226.

[0059] Step 3: The operator screws the lower gasket ring 236 into the upper extension ring 203 again, and makes the lower gasket ring 236 be located at the lower side of the upper ring 222 .

[0060] In step 4, the operator sleeves the connecting ring 205 on the inner side of the rubber ring 226 and clamps the sealing clamp ring 207 in the ring groove 227 during the sleeve installation.

[0061] In step 5, the operator places the sealing inner ring 215 between the connecting ring 205 and the upper extension ring 203, and makes the inner embedded strip 216 located on the inner side pass through the vertical groove 206, and the inner embedded strip 216 located on the outer side pass through the guide groove 204. Thereafter, the connecting ring 205 can be moved upward to make the upper end of the connecting ring 205 flush with the upper end of the upper extension ring 203.

[0062] In step 6, the operator screws the embedded ring 208 between the connecting ring 205 and the upper extension ring 203, thereby completing the sealing connection of the water injection cavity. During the connection, the lower end of the sealing inner ring 215 can act on the upper ring 222 and fix the upper end of the rubber ring 226.

[0063] In step 7, the operator connects the liquid inlet component 4 and the exhaust component 5 to the embedded ring 208 according to the above requirements.

[0064] In this embodiment, when the test paper 606 is being fixed: In step 01 , the operator places the test paper 606 on the placement tray 600 . When placing the test paper 606 , the test paper 606 needs to be bent downward so that the test paper 606 is wrapped around the outer circumference of the placement tray 600 .

[0065] In step 02, the operator rotates the rotating disk 608. As the rotating disk 608 rotates, the oblique hole 611 acts on the screw 612, so that the screw 612 and the pull plate 613 move inward, and the fixed arc plate 614 moves inward, and the test paper is fixed by the fixed arc plate 614. After fixation, the rotating disk 608 is locked by tightening the locking nut 610.

[0066] In step 03, the operator places the placement plate 600 with the test paper 606 on the lower end of the seal 2 and the bottom plate 1. When placing the placement plate 600, the lower sealing ring 231 is located in the avoidance ring groove 615.

[0067] Step 04, the operator places the waterproofing membrane 607 on the test paper 606. After placement, the waterproofing membrane is located between the lower sealing ring 231 and the upper sealing ring 229.

[0068] In this embodiment, when testing the water-impermeability of the waterproof membrane: The operator injects water into a closed space formed by the upward extension ring 203, the connecting ring 205, the upper extension ring 203, the rubber ring 226 and the sealing inner ring 215 through the liquid inlet part 4. In the early stage of injection, as the water is injected, the air in the closed space will act on the exhaust inner tube 500, so that the exhaust inner tube 500 moves upward. At this time, the exhaust hole 505 will enter the exhaust inner tube 500, and then be discharged through the movable tube 506, the seventh hole 509, the air hole 511, the eighth hole 517 and the sixth hole 514. When the air is discharged, the water will move upward along the above path, and then the sealing ball 515 will move upward under the action of buoyancy, and the sealing ball 515 will act on the inner periphery of the second tapered hole 513, so as to achieve the effect of sealing the second tapered hole 513. Then, when the water continues to move outward, due to the sealing effect of the sealing ball 515, the water will not leak out. As water is filled in, it will act on the rubber ring 226, causing the rubber ring 226 to press inward against the outer periphery of the waterproof membrane 607, and finally completing the sealing operation on the peripheral side of the waterproof membrane 607 and the upper wall of the lower sealing ring 231 and the waterproof membrane 607. When the sealing is completed, the water pressure inside can be controlled to keep a constant.

[0069] Then water is injected into the upper side of the waterproof membrane 607 through the water injection pipe 34. After the air at the upper end of the waterproof membrane 607 is exhausted, the water pressure of the injected water is increased and maintained for a period of time. During the water injection process, in order to prevent the rubber ring 226 from moving outward, water is continuously injected inward through the liquid inlet part 4 to ensure the sealing effect.

[0070] After water injection and pressure maintenance for a period of time, the test water is pumped out, and the sealing water is discharged from the liquid inlet 4, and then the waterproof membrane 607 and the like are kept dry, and then the waterproof membrane 607 and the test paper 606 and the like are taken out, and then the test paper 606 is observed, and the waterproof effect of the waterproof membrane is obtained.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
