Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, carries out to the technical solution in inventive embodiments clear, complete Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this The embodiment of invention, those of ordinary skill in the art's every other reality obtained without making creative work Example is applied, shall fall within the protection scope of the present invention.

Reference book attached drawing 1-5 and 7-8 are the embodiment of the present invention, and a kind of bivalve control flusher, feature exists In, including water inlet, main pipeline, drainage switch, upper flushing valve, inlet valve, the first valve for pressure difference, the second valve for pressure difference, pressure measuring cylinder and Lower flushing valve；The upper flushing valve is arranged on the top of bivalve control flusher, and the lower flushing valve is arranged in institute The lower part of bivalve control flusher is stated, after pressing drainage switch, tap water carries out upper draining by upper flushing valve, then presses Water in power bucket carries out lower draining by lower flushing valve, realizes the flushing effect of bivalve control.As shown in Figure of description 1, institute Stating drainage switch is hydraulic valve, carries out water route connection with main pipeline；The main pipeline with the lower part of water inlet junction also Inlet valve is connected with for adjusting the pressure in main pipeline.Main pipeline side water route is connected with flushing valve, the upper punching It washes valve and passed through water pipe and be connected at drainage switch；The main pipeline other side is connected with the first valve for pressure difference, the main pipeline Lower part is connected to pressure measuring cylinder by the second valve for pressure difference.The pressure measuring cylinder is connected to the lower flushing valve by bottom pipe water route； The lower flushing valve passed through water pipe and is connected to first valve for pressure difference.The upper flushing valve and the lower flushing valve have identical Structure.

First and second valve for pressure difference is specifically arranged as shown in Figure of description 6, and for cylindric knot, centre is provided with The rod-like structure of similar screw and the channel for accommodating the rod-like structure.The head of the rod-like structure be provided with sealing ring into Row sealing, the bar portion of the rod-like structure are arranged with spring.In the identical situation of valve for pressure difference two sides pressure, due to the work of spring With the position on the head of the rod-like structure is fixed and is sealed by a seal ring, and both sides will not generate air-flow or water flow Flowing；Pressure at the head for being located at rod-like structure is greater than at the bar portion of rod-like structure, since the relationship of pressure difference makes The rod-like structure is mobile to rod-like structure bar portion direction and compresses the spring, and the sealing of sealing ring is destroyed at this time, both sides The flowing of air-flow or water flow can occur.On the contrary, when the pressure being located at rod-like structure bar portion is greater than at rod-like structure head, Since for valve for pressure difference in the presence of the raised head for compressing the rod-like structure, which will not be destroyed both sides will not at this time Generate the flowing of air-flow or water flow；And the valve for pressure difference is the check valve generated for pressure difference.

When pressing drainage switch, the connection of flushing valve back pressure cavity and water outlet in realization, therefore upper flushing valve goes out first Water rinses on realizing；Since the water in upper flushing valve is gone out, pressure is smaller in the back pressure cavity of upper flushing valve at this time, therefore tap water The upper flushing valve is carried out to add water by the back pressure cavity that main pipeline enters the upper flushing valve.The tap water is also at the same time The second valve for pressure difference can be flowed by gravity, when accumulating to a certain extent, push the head of rod-like structure in valve for pressure difference, make The water for obtaining main pipeline flows into pressure measuring cylinder, and the water of pressure measuring cylinder will be flow in lower flushing valve by bottom pipe at this time, finally be realized The connection of lower flushing valve back pressure cavity and water outlet, to be rinsed under being realized after the of short duration time after being rinsed in upper flushing valve The lower flushing of valve.The lower flushing valve and main pipeline are connected with the first valve for pressure difference, when tap water is infused by water inlet to main pipeline When water, the valve for pressure difference can guarantee that it will not be filled the water by crossing the downward flushing valve of water pipe, to guarantee the water outlet of flushing valve up and down Sequentially.After upper and lower flushing valve rinse up and down, tap water fills the water upper flushing valve by water inlet, passes through simultaneously Pressure measuring cylinder fills the water lower flushing valve.Instantly flushing valve water filling after the completion of, water can by cross water pipe flow to the first valve for pressure difference from And guarantees the pressure difference of the first valve for pressure difference two sides and tap water stopping is filled the water from water filling port.

The preferred embodiment of the present invention has shown and described in above description, as previously described, it should be understood that the present invention is not office Be limited to form disclosed herein, should not be regarded as an exclusion of other examples, and can be used for various other combinations, modification and Environment, and can be changed within that scope of the inventive concept describe herein by the above teachings or related fields of technology or knowledge It is dynamic.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, then it all should be appended by the present invention In scope of protection of the claims.
