The lower end of the spindle spring 57 extends beyond the end face of the sleeve 59 and the plunger 50.
In the initial state: referring to fig. 2, the button 90 is located at the uppermost end of the circular truncated cone protruding from the valve cover 31; the deflector 70 and the pressure lever 50 are fitted at the lowest end position of the pressure lever 50, and the pressure lever 50 is tightly attached to the inner annular surface of the gland 41 under the combined action of the second spring 91 and the first spring 60, and the upper end surface of the limit flange 51 of the pressure lever 50; the second end of the deflector rod 70 is movably nested in the assembly hole 23 of the flap handle 22; the flap cover 20 and the fixed seat 10 of the drain valve are tightly attached together, the sealing is watertight, and the drain hole is closed; the water level line of the water tank is shown as CL_CL in FIG. 2, and as the water tank is filled with water, the water storage cavity, the water containing cavity and the water passing hole are all filled with water, and the water is static and free from flowing.
The user presses the button 90 to put the drain valve in a pressed drain state: referring to fig. 4, 5 and 6, pressing the button 90 downward, the second spring 91, the first spring 60 and the spindle spring 57 are compressed under force; the pressure lever 50 is moved downward by the push button 90, and in this process, the water in the water storage chamber 42 at the bottom of the pressure lever 50 is pressurized, flows from the edge of the Y-shaped ring, the water passing hole 53 to the water containing chamber 43, and then flows into the water tank outside; after the button 90 is pushed to the bottom, the water in the water containing cavity 43 is drained to about 85% (measurement and estimation); during the downward movement of the pressing rod 50, the pressing rod 50 drives the shift lever 70 to rotate as shown in fig. 4; the flap handle 22 moves upwards under the drive of the deflector rod 70, the drain valve flap 20 is pulled up by the flap handle 22, the drain hole 11 is opened, and at the moment, the drain valve enters a drain state, and the water level line CL starts to gradually descend as shown in FIG. 4; the height distance the flap 20 is raised can be set by the distance the plunger 50 is lowered. Pressing the waterway trend of the drainage state: 1. the main drainage channel: most of the water is extruded by the upward water in the pressing process of the button 90 and the pressing rod 50, and the pressure is larger than the pressure of the water borne by the V-shaped upper edge, so that the lower edge of the Y-shaped ring contracts, and the water is discharged from the gap between the Y-shaped ring and the inner wall of the cylinder body and discharged into the water tank; 2. a very small portion of the water can be discharged from the water passing hole 53 in the middle of the pressing lever 50, as shown in fig. 4, into the water tank; 3. the other parts are in a sealed state and are not filled with water.
The release button 90 is pressed, and the pressing rod 50 starts to reset to enable the drainage valve to be in a delayed drainage state: referring to fig. 7, 8 and 9, after the hand leaves the button 90, the second spring 91, the first spring 60 and the spindle spring 57 compressed by the force release the rebound to drive the pressing rod 50 to move upwards; in the process, as the water in the water storage cavity at the bottom of the pressure lever 50 is emptied, the edge of the Y-shaped ring and the inner wall of the cylinder body form a sealing state, the water storage cavity is in a state close to vacuum, the pressure is extremely low, and the inside is in a negative pressure state; as shown in fig. 7, the water passing hole 53 is the only path capable of supplementing water to the water storage cavity 42, and a period of time T is required to fill the water storage cavity 42 due to the small pore diameter (e.g., 1.2mm in diameter) of the water passing hole 42; this time T is the time for the plunger 50 to rise, and since the plunger 50 and the lever 70, the flap lever 22, and the flap 20 are the linkage mechanism, this time T is the time for the flap 20 to reset, i.e., the drain valve drain delay time T is the time that the flap 20 takes to pass from open to closed, i.e., T is not closed, but is not closed quickly. Therefore, the preset aperture size of the water passing hole determines the time T for filling the water storage cavity with water, namely the time T for the pressure lever 50 to rise and reset to the original state; therefore, the invention can change the time T of delayed drainage by changing the size of the aperture; meanwhile, the second spring 91, the first spring 60, and the spindle spring 57 also have an important influence on the drainage time T; the technical parameters of the second spring 91, the first spring 60 and the mandrel spring 57 are comprehensively adjusted, and the optimal time T for delaying drainage of the drain valve can be effectively changed by matching with the adjustment of the diameter of the water passing hole. Delay drainage state, waterway trend: as in fig. 7: the water passing hole 53 continuously feeds water, and the pressure lever 50 continuously moves upwards slowly until the limit flange 51 abuts against the pressure cover 41; then stopping the motion to finish a time delay action process; at the same time, the button 90, the shift lever 70 and the flap 20 are reset to return to the initial state before the button is pressed; in this process, the gland stem 22 is further connected with a connecting rod 32 in a driving manner, the connecting rod 32 controls the inlet valve to be opened, so that the external water flows through the inlet pipe 33, the flow increasing pipe 34 and the inlet valve to supplement water to the water tank, the water level line gradually rises to be close to cl_cl in fig. 7, the water level line of the water tank rises to a preset CL water level line, the water tank is supplemented, and the water tank is reset to an initial state as shown in fig. 2.
The foregoing description is only illustrative of the preferred embodiments of the present invention, and therefore should not be taken as limiting the scope of the invention, for all changes and modifications that come within the meaning and range of equivalency of the claims and specification are therefore intended to be embraced therein.
