technical field

The invention relates to a waterproof coiled material testing instrument. the

Background technique

At present, the detection of the impermeability of known thin waterproof membranes mostly relies on visual inspection, which has a large error and does not meet the product quality requirements. Few of them use detectors for detection, but the current waterproof membrane detectors have common shortcomings: large volume, complex structure, troublesome operation and power consumption, complex calculations when using the tester, high requirements for testers, and the current Some detectors are not strict enough to grasp the national testing standards. the

Contents of the invention

In order to overcome the defects of the above detectors, the utility model provides a waterproof membrane detector with simple structure, small size, convenient operation, low inspection cost, no power consumption, and environmental protection and safety. the

The utility model is realized through the following technical solutions: a waterproof coiled material detector, including a water tank, a pressure gauge, a circular pressure base, an upper pressure flange, an exhaust valve, a leather tube, and an exhaust valve on the upper part of the wall of the circular pressure base The exhaust pipe passes through, and the exhaust pipe is externally connected to the exhaust valve, and the internal part extends into the cavity of the circular pressure base, and its opening is located slightly lower than the upper edge of the circular pressure base. Several pressure screws are installed on the upper part of the outer wall of the circular pressure base, and the lower rubber sealing gasket, thin waterproof membrane test sample, lower laboratory filter paper, moisture indicator mixture, etc. can be placed between the circular pressure base and the upper pressure flange. Filter paper for the upper laboratory, round plexiglass, upper rubber sealing gasket, and connected to the pressure screw on the circular pressure base through several pairs of pressure nuts, the water inlet and outlet pipes are installed at the bottom of the circular pressure base and connected to the water inlet and outlet valves, water The inlet and outlet valves are connected to the connecting pipe, the connecting pipe is connected to the A tee, the water outlet valve is connected to the other end of the A tee, the water outlet pipe is connected to the water outlet valve, the upper end of the A tee is connected to the B tee, and the upper end of the B tee is connected to the water outlet valve. The leather tube is connected, the leather tube is connected with the drain valve, the drain valve is connected with the water tank, and the other end of the B tee (23) is connected with the pressure gauge (22). the

Further, the volume of the water tank is three times greater than that of the isomorphic pressure base. the

Further, the length of leather tube (19) exceeds 6 meters. the

Its working principle is: when in use, first close the water discharge valve and the water outlet valve, fill the water tank with water, and place the water tank at a height of 6 meters above the circular pressure base (according to the national testing standard, the test piece must meet the pressure of 60kPa for 24 hours ). Place the circular pressure base horizontally, place the lower rubber sealing gasket, thin waterproof membrane test sample block, lower laboratory filter paper, moisture indicator mixture (need to spread evenly), upper laboratory filter paper, circular plexiglass and The upper rubber sealing gasket is placed on the circular pressure base layer by layer, the upper pressure flange is covered, and several pairs of pressure nuts are used to seal the upper pressure flange and the circular pressure base to form a low-pressure detection device. In this way, the lower part of the low-pressure detection device forms a sealed pressurized chamber between the waterproof coiled material test sample block and the circular pressure base. The pipe is connected with the A tee, the A tee is connected with the B tee, the B tee is connected with the leather tube, the leather tube is connected with the water discharge valve, and the water discharge valve is connected with the water tank. the

The upper part of the low-voltage detection device forms a sealed display chamber between the circular plexiglass and the thin waterproof membrane test sample block. The display chamber is covered with lower laboratory filter paper, moisture indicating mixture and upper laboratory filter paper from bottom to top. The upper and lower laboratory filter papers keep the moisture indicating mixture powder between them from scattering, and keep the inside of the display chamber clean. The lower laboratory filter paper has good hygroscopicity. In case of moisture, it can be uploaded to the moisture indicator mixture immediately. The upper laboratory filter paper is translucent. If it meets water, it becomes transparent. Through the plexiglass and the upper laboratory filter paper, the moisture can be clearly observed to indicate whether the mixture has changed color. the

When testing, open the air release valve, the upper valve and the water inlet and outlet valves. Since the water tank is filled with water at a certain height and placed at a height of more than 6 meters above the circular pressure base, the water immediately enters the pressurized chamber of the detection device. At the same time, the air in the pressurized chamber is discharged. When water flows out from the exhaust valve, it means that the gas in the pressurized chamber has been exhausted, and the exhaust valve is quickly closed. The test sample block produces a pressure greater than 60kPa. The water pressure can be observed from the pressure gauge, and the above-mentioned pressurized state is maintained for more than 24 hours according to the national testing standard. After reaching this standard, organic Glass and upper laboratory filter paper are used to observe whether the moisture on the thin waterproof membrane test sample is discolored. If the color does not change, the water impermeability of the test sample is qualified, and the discoloration indicates that the water impermeability of the test sample is unqualified. The detection is very convenient, accurate and reliable. the

After the test is completed, close the water discharge valve, open the exhaust valve, water inlet and outlet valve and water outlet valve, and the water in the pressurized chamber, external pipe and valve of the testing device will be automatically discharged through the outlet pipe. Unscrew the pressure nut, open the upper pressure flange, take out the upper rubber sealing gasket, round plexiglass, upper laboratory filter paper, moisture indicator mixture, and lower laboratory filter paper (in order to prevent the moisture indicator mixture from scattering, the upper laboratory Use filter paper, moisture indicator mixture, lower experiment filter paper three layers taken out at the same time), thin waterproof membrane test sample block and lower rubber sealing gasket. If you need to test again, you only need to fill the water tank with the water consumed in the previous test, and repeat the above operation. the

Compared with similar waterproof coil detectors, the utility model is composed of a solid water tank, a pressure gauge, a circular pressure base, an upper pressure flange, an exhaust valve, and a leather tube, and has the advantages of simple structure, convenient manufacture and maintenance. In addition, the practical real-type detector does not need to calculate when used, and the requirements for the inspectors are not high, and the detection is very convenient, accurate and reliable. The detector does not need a power source, has low inspection cost, and is environmentally friendly and safe. the
