Description

Technical Field

[0001] The invention relates to a hydraulic control device capable of quantitative drainage and a control method for quantitative drainage thereof. Background Art

[0002] Hydraulic drain valves have been widely used in sanitary ware toilet flushing and drainage technology products. The amount of drainage is determined by the length of time the tap water is supplied. The manual water supply time is very inaccurate, so the drain valve opening time varies greatly each time. Coupled with other factors, the difference in drainage is even greater, which is not conducive to the principle of water conservation and the flushing and cleaning effect of toilet waste. Therefore, it is necessary to find a good technical solution product to realize a drain valve with controllable quantitative drainage to meet the water volume required for the toilet flushing function, and achieve the purpose of flushing and cleaning without wasting water. Summary of the invention

[0003] The present invention discloses a hydraulic drainage device capable of setting and controlling the drainage volume of a water tank, which is a system device utilizing fluid pressure control and a mechanism method capable of setting and controlling the same, thereby overcoming the shortcomings of the background technology.

[0004] The present invention is achieved through the following technical solutions:

[0005] The technical solution adopted by the present invention is a hydraulic drainage device capable of adjusting, setting and controlling the drainage volume, comprising a hydraulic drainage component and a quantitative drainage control assembly.

[0006] The hydraulic drainage component is a hydraulic device that uses the water pressure of tap water to push the piston in the hydraulic cylinder to move, the piston drives the drainage valve to open to achieve drainage, and uses mechanical force to push the piston to discharge the water in the hydraulic cylinder. The return of the piston drives the drainage valve to close to stop the water. The hydraulic drainage component is composed of a hydraulic cylinder body, a piston, a spring, a spring gland, a water seal ring, and a drainage valve.

[0007] A guide sleeve is arranged at the center of the hydraulic cylinder body.

[0008] A hollow conduit is arranged at the center of the piston, the conduit is arranged in the guide sleeve, and the conduit and the guide sleeve are in a movable matching relationship.

[0009] A sealing ring is arranged between the conduit and the guide sleeve.

[0010] A water seal ring is arranged between the piston and the main body of the hydraulic cylinder. The top of the piston presses a spring, and a drain valve is arranged at the bottom of the piston guide tube.

[0011] The main body of the hydraulic cylinder is provided with a water inlet limiting hole and a water outlet, and the water outlet is provided with a quantitative drainage control component.

[0012] The quantitative drainage control component is installed on the water outlet of the hydraulic drainage component. The main body of the quantitative drainage control component is movably connected to the lever through a pin. A soft rubber plug is provided on the top of the lever. The soft rubber plug can be pressed on the water outlet to close the water outlet, so that a closed pressure chamber is formed in the hydraulic cylinder.

[0013] The rear end of the lever is provided with an adjusting screw rod, and the adjusting screw rod is provided with a float, and the float rod can be adjusted to a set position on the screw rod.

[0014] The lever can amplify the pressure exerted by the buoyancy of the float on the soft rubber plug.

[0015] The aperture of the water inlet limiting hole is smaller than the aperture of the water outlet.

[0016] The purpose of setting the water inlet limiting hole is that when the drainage water supply valve continues to supply water, the water inlet flow rate is less than the water outlet flow rate, which can ensure that when the drainage water level in the water tank drops to the set drainage level, the buoy can fall instantly, the soft rubber plug on the lever leaves the water outlet, the water in the hydraulic cylinder is immediately and fully discharged, the pressure in the hydraulic cylinder is reduced, and the piston can fall instantly to close the drain outlet, thereby achieving the purpose of quantitative drainage without causing drainage error.

[0017] The adjusting screw on the lever can be used for the float thread to adjust and set the float water surface position, and the float descends to open the drain port to release the water pressure in the hydraulic cylinder, thereby achieving the set quantitative drainage.

[0023] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0024] like Figure 1As shown, the present invention provides a hydraulic drainage device capable of adjusting, setting and controlling the drainage volume, including a hydraulic drainage component 1 and a quantitative drainage control component 4. The hydraulic drainage component 1 is composed of a hydraulic cylinder body 101, a piston 102, a spring 103, a spring pressure cover 105, a water seal ring 104, and a drainage valve 111. A guide sleeve 107 is provided at the center of the hydraulic cylinder body 101. A hollow conduit 106 is provided at the center of the piston 102, and the hollow conduit 106 is arranged in the guide sleeve 107, and the conduit 106 and the guide sleeve 107 are in a movable matching relationship. A sealing ring 110 is provided between the hollow conduit 106 and the guide sleeve 107. A water seal ring 104 is provided between the piston 102 and the hydraulic cylinder body 101. The spring 103 is pressed on the top of the piston 102, and a drainage valve 111 is provided at the bottom of the conduit 106 of the piston 102. The hydraulic cylinder body 101 is provided with a water inlet limiting hole 108 and a water outlet 109, and the water outlet 109 is provided with a quantitative drainage control component 4. The quantitative drainage control component 4 is movably connected to the lever 401 through a pin 405, and a soft rubber plug 404 is provided on the top of the lever 401. The soft rubber plug 404 can press on the water outlet 109 to close the water outlet 109, so that a closed pressure chamber is formed in the hydraulic cylinder body 101.

[0025] Now combined Figure 2 To further illustrate the present invention, a controllable quantitative hydraulic drainage device of the present invention is installed on a drain outlet 113 in a water tank. A water inlet component 2 is provided in the water tank. The water inlet component 2 can set the water storage capacity (water level) in the water tank. At this time, the drain valve 111 is pressed against the drain outlet 113 of the drain seat 112 by the pressure of the spring 103. At the same time, the float 402 on the quantitative drainage control component 4 is immersed in water. The buoyancy of the float 402 presses the soft rubber plug 404 against the water outlet 109 through the lever 401, so that a closed state is formed in the hydraulic cylinder body 101.

[0026] Now combined Figure 3 To further illustrate the present invention, when drainage is required, the drainage water supply valve 3 is started, and the pressurized water flows into the hydraulic cylinder body 101 from the limited small hole 108 through the water supply pipe 5. Due to the action of the water seal ring 104 and the sealing ring 110 and the action of the lever 401 of the quantitative drainage control component 4 on the water outlet 109, the soft rubber plug 404 blocks the water outlet 109, and the water pressure in the cavity of the hydraulic cylinder body 101 increases. The water pressure pushes the piston 102 to overcome the elastic force of the spring 103 and move upward. The central hollow conduit 106 of the piston 102 drives the drainage valve 111 to open the drainage port 113 to achieve drainage.

[0027] Now combined Figure 4The operation of the quantitative drainage closing valve of the present invention is further explained. When the water in the water tank is discharged, the water level drops rapidly. When the water level drops to the point where the float 402 loses its buoyancy, the float 402 drives the lever 401 to fall and leave the water outlet 109 at the same time. The water in the hydraulic cylinder body 101 is immediately discharged from the cylinder, and the elastic force of the spring 103 pushes the piston 102 to its original position. At the same time, the drain valve 111 closes the drain outlet 113, stopping the water in the water tank from being discharged further.

[0028] Now combined Figure 5 The buoy of the present invention is further described when the water level is low. The position of the buoy 402 on the quantitative drainage control assembly 4 can achieve different drainage amounts according to the water storage amount of the water tank and the drainage amount to be set.
