Description

TECHNICAL FIELD

[0001] The utility model relates to flushing water tank test technical field especially uses the flushing water tank safety water level testing arrangement of toilet. BACKGROUND

[0002] Ceramic toilet, flushing water tank and squatting toilet are used together, and have been widely used in every family, and the unqualified items of toilet gravity type flushing water tank include flushing water tank safety water level and rated flushing water volume,

[0003] In GB / T 26730-2011, the determination method of flushing water tank rated flushing water volume is to determine the average water volume as rated flushing water volume according to GB / T 6952-2015, and the working water level line at static pressure 0.14MPa is the rated flushing water volume marking line. The technical requirement of rated flushing water volume is that the rated flushing water volume and its corresponding marking line should be marked on the inner wall of water tank or drain valve, and the allowable deviation is ±5mm; for the flushing water tank with adjustable water volume, at least the maximum rated flushing water volume and its corresponding marking line should be marked. The unqualified conditions of the project are as follows: (1) the rated flushing water volume and its corresponding marking line are not marked on the drain valve or the inner wall of water tank; (2) the corresponding marking line is marked, and the rated flushing water volume is not marked; (3) the rated flushing water volume and the corresponding marking line are marked, and the deviation exceeds 5mm.

[0004] The safety water level includes the distance between working water level, overflow water level, full-overflow water level, critical water level and the lowest water level of non-sealing mouth, which is represented as h1, h2, h3, h4 and h5 in the standard, as shown in Figure 1 h1=WL-OL, h2=OL-CL, h3=SL-CL, h4=SL-NL and h5=OL-SL.

[0005] h1 is the distance between overflow water level and working water level: the working water level should be lower than the overflow water level by 10mm-38mm, and the purpose is to prevent toilet from leaking due to water pressure change and prevent unnecessary waste of water resources.

[0006] h2 is the distance between critical water level and overflow water level: the vertical distance should be not less than 25mm. In order to prevent the water in the water tank from flowing back to the water supply pipe to cause secondary pollution of drinking water when the full-open state of the inlet valve sealing fails to reach the full-overflow water level, the siphon is not caused by the change of pipeline pressure. The flow rate of the full-open inlet valve, water pressure, overflow capacity of the drain valve, cross-sectional area of the water tank and many other factors will affect the height of the full-overflow water level.

[0007] h4 is the lowest position of the non-sealing port of the water tank should be higher than the overflow water level by 5mm. The design purpose is to prevent the toilet water from leaking out when the water level in the water tank reaches the overflow water level and the water inlet valve is out of control. The event of the newly renovated house being flooded by the toilet water leakage is due to the height of the overflow pipe in the water tank being higher than the installation height of the water handle, the water pressure is higher at night, the water inlet valve is out of control, the water in the water tank flows out of the handle hole, causing the consumer to suffer great losses.

[0008] The safety water level test is measured according to GB / T 26730-2011, and the safety water levels h1, h2, h3, h4 and h5 are measured by using a steel ruler after water is filled in the water tank. There are the following problems in the test process: (1) the flushing water tank interior space is narrow, and when reading the steel ruler, the line of sight cannot be perpendicular to the steel ruler, which increases the uncertainty of reading to some extent; (2) as shown in the relative water level diagram of the flushing water tank interior parts installation, the distance between the water levels is difficult to accurately position during measurement, which affects the measurement efficiency.
