Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
1-5 and 7-8 of the accompanying drawings, which are embodiments of the present invention, a dual-valve control flushing device is characterized by comprising a water inlet, a main pipeline, a drainage switch, an upper flushing valve, an air suction valve, a first differential pressure valve, a second differential pressure valve, a pressure cylinder and a lower flushing valve; the upper flushing valve is arranged on the upper part of the double-valve control flushing device, the lower flushing valve is arranged on the lower part of the double-valve control flushing device, tap water is discharged upwards through the upper flushing valve after a water discharge switch is pressed down, and then water in the pressure barrel is discharged downwards through the lower flushing valve, so that the flushing effect of double-valve control is realized. As shown in the attached figure 1 of the specification, the drainage switch is a hydraulic valve which is connected with the main pipeline in a waterway way; the lower part of the joint of the main pipeline and the water inlet is also connected with an air suction valve for adjusting the pressure intensity in the main pipeline. An upper flushing valve is connected to a waterway at one side of the main pipeline and is connected to a drainage switch through a water pipe; the other side of the main pipeline is connected with a first differential pressure valve, and the lower part of the main pipeline is connected to the pressure cylinder through a second differential pressure valve. The pressure cylinder is connected to the lower flushing valve through a bottom pipeline waterway; the lower flush valve is connected to the first differential pressure valve by a water line. The upper flush valve and the lower flush valve have the same structure.
The first and second differential pressure valves are specifically configured as shown in fig. 6 of the specification, which is a cylindrical junction with a screw-like rod-like structure disposed therebetween and a channel for receiving the rod-like structure. The head of the rod-shaped structure is provided with a sealing ring for sealing, and the rod part of the rod-shaped structure is sleeved with a spring. Under the condition that the pressure of the two sides of the differential pressure valve is the same, the positions of the heads of the rod-shaped structures are fixed and sealed through the sealing rings under the action of the springs, and air flow or water flow cannot be generated at the two sides; when the pressure at the head of the rod-shaped structure is greater than that at the rod-shaped structure, the rod-shaped structure moves towards the rod-shaped structure and compresses the spring due to the pressure difference, and the sealing of the sealing ring is broken, and air flow or water flow can occur at two sides. Conversely, when the pressure at the rod part of the rod-shaped structure is higher than that at the head part of the rod-shaped structure, the sealing structure is not damaged and no air flow or water flow is generated at the two sides because the pressure difference valve is provided with a bulge to press the head part of the rod-shaped structure; and the differential pressure valve is a one-way valve for generating pressure difference.
When the drainage switch is pressed down, the back pressure cavity of the upper flushing valve is communicated with the water outlet, so that the upper flushing valve firstly discharges water to realize upper flushing; because the water in the upper flushing valve is flushed out, the pressure in the back pressure cavity of the upper flushing valve is smaller at the moment, so that tap water enters the back pressure cavity of the upper flushing valve through the main pipeline to add water to the upper flushing valve. Meanwhile, the tap water can flow into the second differential pressure valve under the action of gravity, when the tap water is accumulated to a certain degree, the head of the rod-shaped structure in the differential pressure valve is pushed to enable the water in the main pipeline to flow into the pressure cylinder, at the moment, the water in the pressure cylinder flows into the lower flushing valve through the bottom pipeline, and finally, the communication between the back pressure cavity of the lower flushing valve and the water outlet is realized, so that the lower flushing of the lower flushing valve is realized after a short time passes after the upper flushing valve is flushed. The lower flushing valve is connected with the main pipeline through a first differential pressure valve, when tap water is injected into the main pipeline through the water inlet, the differential pressure valve can ensure that the tap water cannot be injected into the lower flushing valve through the water pipe, and therefore the water outlet sequence of the upper flushing valve and the lower flushing valve is ensured. After the upper and lower flushing valves perform up and down flushing, tap water fills the upper flushing valve through the water inlet, and simultaneously fills the lower flushing valve through the pressure cylinder. After the water injection of the lower flushing valve is completed, water can flow to the first differential pressure valve through the water pipe, so that the pressure difference at two sides of the first differential pressure valve is ensured, and tap water stops injecting water from the water injection port.
While the foregoing description illustrates and describes the preferred embodiments of the present invention, as noted above, it is to be understood that the invention is not limited to the forms disclosed herein but is not to be construed as excluding other embodiments, and that various other combinations, modifications and environments are possible and may be made within the scope of the inventive concepts described herein, either by way of the foregoing teachings or by those of skill or knowledge of the relevant art. And that modifications and variations which do not depart from the spirit and scope of the invention are intended to be within the scope of the appended claims.
