TABLE 1
| Test item | Example 1 | Example 2 | Comparative example 1 | Comparative example 2 |
| Hydraulic sealing performance of water | No leakage and no damage | No leakage and no damage | Occurrence of leakage | No leakage and no damage |
| Static pressure sealing Property of Water | No leakage and no damage | No leakage and no damage | Occurrence of leakage | No leakage and no damage |
| Sealing property of gas | No leakage and no damage | No leakage and no damage | Occurrence of leakage | No leakage and no damage |
The test method of the static pressure sealing performance of the water is as follows:
The connecting conduit is arranged at the bottom of the toilet 30, the toilet seat of the toilet and the other port of the connecting conduit are sealed, and a water valve is connected to the toilet seat of the toilet; opening a water valve to fill water until the toilet bowl and the connecting guide pipe are full of water, and closing the water valve; resting for 30 minutes, the seal was observed.
Inspection standard: and the connecting conduit is free from damage and leakage at the sealing part after the connecting conduit is stationary for 30 minutes.
The method for testing the flow pressure sealing performance of water comprises the following steps:
The connecting guide pipe is arranged at the bottom of the toilet, the toilet seat of the toilet and the other end opening of the connecting guide pipe are opened, and a water valve is connected to the toilet seat of the toilet; opening a water valve to feed water with the pressure of 0.2MPa, and closing the water valve; resting for 30 minutes, the seal was observed.
Inspection standard: and the connecting conduit is free from damage and leakage at the sealing part after the connecting conduit is stationary for 30 minutes.
The test method of the sealing performance of the gas is as follows:
The connecting guide pipe is arranged at the bottom of the toilet, the toilet seat of the toilet and the other end opening of the connecting guide pipe are sealed, and the air valve and the pressure gauge are connected to the toilet seat of the toilet; the connected toilet bowl and the connecting guide pipe are placed in a transparent water tank to be submerged; after the air valve is submerged, opening the air valve to inject air, and closing the air valve when the pressure value displayed by the pressure gauge is 0.04 MPa; and standing for 30 minutes, and observing whether bubbles are generated at the connection sealing position of the toilet and the connecting guide pipe in the water tank.
