Description
Technical field:
The present invention relates to waterproof roll watertightness detecting instrument, refer in particular to the low pressure detecting instrument of fitting roll of waterproof sheets watertightness for building.
Background technology:
The detection great majority of present known fitting roll of waterproof sheets watertightness rely on range estimation, and this detection error is large, does not conform to the product quality requirement.Patent No. CN2442261Y disclosed " a kind of anti-leakage property test instrument for water-proof coiled material " and the impervious device of the disclosed fitting roll of waterproof sheets of patent No. CN2556635Y have common shortcoming: volume is large, complex structure, troublesome poeration and need power consumption.Calculation of complex especially when the tester of last patent disclosure uses requires height to the testing staff.And these several detectors are grasped strict not to national examination criteria.
Summary of the invention:
For overcoming many defectives of present existence, the present invention design a kind of simple in structure, volume is little, easy to operate, fitting roll of waterproof sheets watertightness low pressure detecting instrument that inspection cost gently, does not need power consumption and Environmental Safety.
Fitting roll of waterproof sheets watertightness low pressure detector of the present invention comprises water tank, tensimeter, round pressure base, upward pressure flange, drain tap, leather hose (length is more than 6 meters).The volume of water tank is greater than three times of round pressure base volume.Round pressure base wall top has gas outlet to pass, the outside drain tap that connects of gas outlet, and extend in the round pressure base cavity inside, and its opening is positioned at slightly lower of round pressure base upper limb.Several pressure screw bolts are installed in round pressure base outer wall top.Can insert lower rubber gasket, fitting roll of waterproof sheets test specimens piece, lower paper for laboratory use,filter, moisture indicating mixture between round pressure base and upward pressure flange and (be the fine-powdered thing, meet the water variable color), upper paper for laboratory use,filter, circular organic glass, upper rubber gasket, and by several pressure screw bolt on pressure nut and the round pressure base is flexibly connected.Water inlet pipe and water outlet pipe be installed in round pressure base bottom and is connected with water turnover valve, water passes in and out valve and is connected with connecting leg, connecting leg is connected with the A threeway, flowing water Valve is connected to the other end of A threeway, rising pipe is connected with flowing water Valve, the upper end of A threeway is connected with the B threeway, and the upper end of B threeway is connected with leather hose, and leather hose is connected with Draw off valve, Draw off valve is connected with water tank, and tensimeter is installed in the other end of B threeway.
Principle of work of the present invention is such: during use, close first Draw off valve and flowing water Valve, at the in-built full water of water tank, and water tank is placed on above 6 meters At The Heights of round pressure base (need satisfy 60kPa pressure 24 hours by national examination criteria test specimen).With round pressure base horizontal positioned, successively lower rubber gasket, fitting roll of waterproof sheets test specimens piece, lower paper for laboratory use,filter, moisture indicating mixture (needing to spread evenly), upper paper for laboratory use,filter, circular organic glass and upper rubber gasket successively are placed on above the round pressure base, cover the upward pressure flange, and to pressure nut the upward pressure flange is connected with several with the round pressure base seal, form the low pressure pick-up unit.A sealing pressing storehouse is formed between fitting roll of waterproof sheets test specimens piece and round pressure base at low pressure pick-up unit bottom like this, and the pressurization storehouse is connected with water inlet pipe and water outlet pipe, water inlet pipe and water outlet pipe is connected with water turnover valve, water turnover valve is connected with connecting leg, connecting leg is connected with the A threeway, the A threeway is connected with the B threeway, the B threeway is connected with leather hose, leather hose is connected with Draw off valve again, Draw off valve is connected with water tank.Low pressure pick-up unit top forms a sealing demonstration storehouse at circular organic glass and fitting roll of waterproof sheets test specimens interblock.Show in the storehouse and be covered with lower paper for laboratory use,filter, moisture indicating mixture, upper paper for laboratory use,filter from bottom to top.Upper and lower laboratory filter paper is not scattered moisture indicating mixture pulvis therebetween, keeps showing cleaning in the storehouse.Lower laboratory filter paper good hygroscopicity such as moisture content, can be uploaded to the moisture indicating mixture at once.Upper laboratory filter paper is translucent, such as the water bleach, but sees through organic glass and upper laboratory filter paper clear view to the whether variable color of moisture indicating mixture.
Open the venting valve during detection, upper valve and water turnover valve, because the water of certain altitude water level is housed in the water tank, and place above the height of round pressure base more than 6 meters, so water enters the pressurization storehouse of pick-up unit at once, discharge simultaneously the air in the pressurization storehouse, when having water to flow out from drain tap, illustrate that the gas in the pressurization storehouse drains, close rapidly drain tap, at this moment the water in the water tank produces pressure greater than the pressure of 60kPa to the fitting roll of waterproof sheets test specimens piece that detects, can be observed the size of hydraulic pressure from tensimeter, and keep above-mentioned pressurized state more than 24 hours according to national examination criteria, after reaching this standard, on pick-up unit, can see through organic glass and upper paper for laboratory use,filter and observe whether variable color of moisture indicating mixture on the fitting roll of waterproof sheets test specimens piece, nondiscolouring is that test specimens piece watertightness is qualified, and variable color is that test specimens piece watertightness is defective.Detect very convenient, and accurately and reliably.
After detection is finished, close Draw off valve, open drain tap, water turnover valve and flowing water Valve, the water in pick-up unit pressurization storehouse and exterior tube, the valve is discharged automatically through rising pipe.Twist and remove pressure nut, open the upward pressure flange, rubber gasket, circular organic glass, upper paper for laboratory use,filter, moisture indicating mixture, lower paper for laboratory use,filter (being scattered upper paper for laboratory use,filter, moisture indicating mixture, three layers of simultaneously taking-up of lower paper for laboratory use,filter for preventing the moisture indicating mixture), waterproof roll test specimens piece and lower rubber gasket in the taking-up.Again detect such as need, only need in water tank, to fill into the water that exhausts in once detecting, and the repetition aforesaid operations gets final product.
