Description

Technical Field

[0001] The utility model relates to the technical field of one-way valves, in particular to an anti-clogging one-way valve. Background Art

[0002] A one-way valve is a liquid mechanical device. Its specific principle is that when the liquid flows in the allowed direction, the valve disc will be opened to allow the liquid to pass through, and when the liquid flows in the opposite direction, the valve disc will automatically close to prevent the liquid from flowing back.

[0003] The two ends of the one-way valve are generally connected to a liquid inlet pipe and a liquid outlet pipe, and a filter is set in the infusion pipe to filter out particulate impurities in the liquid.

[0004] At present, after long-term use, the filter screen of the liquid inlet pipe on the existing one-way valve will accumulate acidic and alkaline particle impurities in the filter mesh, causing blockage, preventing the liquid from flowing normally, and affecting the normal use of the one-way valve body.

[0005] Therefore, a structure for preventing the liquid inlet pipe from being blocked on the one-way valve body is needed to solve the above problem. Utility Model Content

[0006] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose an anti-clogging one-way valve.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] An anti-clogging one-way valve is designed, comprising a one-way valve body, wherein both ends of the one-way valve body are respectively connected to a liquid inlet pipe and a liquid outlet pipe, a filter is provided in the liquid inlet pipe, a first pipe valve and a second pipe valve are respectively provided on the liquid inlet pipe, a mounting seat is provided on the liquid inlet pipe, and a sewage pipe is connected to the lower left end of the liquid inlet pipe;

[0009] An alkali liquid storage tank and an acid liquid storage tank are respectively provided on the mounting seat, a sewage valve and a sewage pump are provided on the sewage pipe, an alkali liquid nozzle is connected to the alkali liquid storage tank, an acid liquid nozzle is connected to the acid liquid storage tank, an alkali liquid pump and an alkali liquid pipe valve are provided on the alkali liquid nozzle, and an acid liquid pump and an acid liquid pipe valve are provided on the acid liquid nozzle;

[0010] The top end of the alkali liquid storage tank is provided with an alkali liquid filling pipe, and the lower end of the acid liquid storage tank is provided with an acid liquid filling pipe.

[0011] Furthermore, the alkali solution nozzle is an L-shaped structure as a whole, passes through the mounting seat and is inserted into the liquid inlet pipe, and the alkali solution nozzle is located in the inner cavity of the liquid inlet pipe and is inclined toward the right end surface of the filter screen.

[0012] Furthermore, the acid liquid nozzle is an L-shaped structure as a whole, passes through the mounting seat and is inserted into the liquid inlet pipe, and the acid liquid nozzle is located in the inner cavity of the liquid inlet pipe and is inclined toward the right end surface of the filter screen.

[0013] Furthermore, the alkali liquid pump is fixedly arranged at the top end of the mounting seat, and the acid liquid pump is fixedly arranged at the lower end of the mounting seat. The alkali liquid pump can effectively pump the alkaline cleaning liquid at high pressure, and the acid liquid pump can effectively pump the acidic cleaning liquid at high pressure.

[0014] Furthermore, the sewage pipe is arranged in a vertical downward direction, the upper end of the sewage pipe is connected to the inner cavity of the liquid inlet pipe, and the sewage valve is arranged near the liquid inlet pipe. The sewage pipe arranged in a vertical downward direction and combined with the suction force of the sewage pump can quickly pump out the sewage.

[0015] Furthermore, the mounting seat is a rectangular parallelepiped structure and is fixedly mounted on the outer wall of the liquid inlet pipe. The mounting seat is made of stainless steel, which is rust-resistant, strong and non-deformable.

[0018] 1. The utility model provides a mounting seat on the liquid inlet pipe of the one-way valve body, and symmetrically provides alkaline solution and acid solution spraying structures on the mounting seat, thereby realizing step-by-step targeted spraying of acidic particle impurities and alkaline particle impurities accumulated in the mesh of the filter screen, and effectively dissolving the corresponding alkaline or acidic cleaning liquid to form sewage. After cleaning, the sewage will be effectively discharged through the sewage pipe, effectively avoiding the situation where the liquid cannot flow normally due to filter screen blockage during long-term use, thereby ensuring the normal use of the one-way valve body.

[0029] An alkali liquid filling pipe 50 is provided at the top of the alkali liquid storage tank 5, and an acid liquid filling pipe 60 is provided at the lower end of the acid liquid storage tank 6. Manual valves are respectively provided on the alkali liquid filling pipe 50 and the acid liquid filling pipe 60. The valves are opened and connected to the external liquid filling tank. In combination with the liquid filling pump, convenient replenishment of alkaline cleaning liquid or acidic cleaning liquid can be achieved.

[0030] Alkaline cleaning liquid or acidic cleaning liquid are both existing technologies to achieve cleaning effects.

[0031] The one-way valve body 1 , the liquid outlet pipe 11 , and the liquid inlet pipe 2 are integrated into one body, which is the prior art. The liquid flows from left to right in the liquid inlet pipe 2 .

[0032] The alkali solution nozzle 51 is an L-shaped structure as a whole. The alkali solution nozzle 51 passes through the mounting seat 4 and is inserted into the liquid inlet pipe 2. The inner cavity of the alkali solution nozzle 51 in the liquid inlet pipe 2 is inclined toward the right end face of the filter 20, so as to realize the comprehensive high-pressure spraying of alkaline cleaning liquid toward the surface of the filter 20.

[0033] The acid liquid nozzle 61 is an L-shaped structure as a whole. The acid liquid nozzle 61 passes through the mounting seat 4 and is inserted into the liquid inlet pipe 2. The inner cavity of the acid liquid nozzle 61 in the liquid inlet pipe 2 is inclined toward the right end face of the filter screen 20, so as to realize the comprehensive high-pressure spraying of the acidic cleaning liquid toward the surface of the filter screen 20.

[0034] The alkali liquid pump 52 is fixedly arranged at the top end of the mounting seat 4, and the acid liquid pump 62 is fixedly arranged at the lower end of the mounting seat 4. The alkali liquid pump 52 can effectively pump the alkaline cleaning liquid at high pressure, and the acid liquid pump 62 can effectively pump the acidic cleaning liquid at high pressure.

[0035] The sewage pipe 3 is arranged in a vertical downward direction, and the upper end of the sewage pipe 3 is connected to the inner cavity of the liquid inlet pipe 2. The sewage valve 31 is arranged near the liquid inlet pipe 2. The sewage pipe 3 arranged in a vertical downward direction and combined with the suction force of the sewage pump 32 can quickly and cleanly pump out the sewage.

[0036] The mounting base 4 is a rectangular parallelepiped structure and is fixedly mounted on the outer wall of the liquid inlet pipe 2. The mounting base 4 is made of stainless steel, which is rust-resistant, strong and non-deformable.

[0037] A connecting plate 33 is provided between the housing of the sewage pump 32 and the mounting seat 4 to ensure a stable installation of the sewage pump 32 .

[0038] Working method: Acidic and alkaline particles will accumulate on the mesh of the filter 20 after long-term use. First, close the first pipe valve 21 and the second pipe valve 22, then open the sewage valve 31 and the lye pipe valve 53, and then start the lye pump 52. The lye pump 52 will pump out the alkaline cleaning liquid stored in the lye storage tank 5, and then spray the liquid toward the right end surface of the filter 20 through the lye nozzle 51, so that the acidic particles can be effectively dissolved to form sewage. Then start the sewage pump 32 to discharge the current sewage through the sewage pipe 3.

[0039] Next, the sewage pump 32, the alkali pump 52, and the alkali pipe valve 53 are closed, and the acid pump 62 and the acid pipe valve 63 are opened at the same time. The acid pump 62 can pump out the acid cleaning liquid stored in the acid storage tank 6, and then spray the acid cleaning liquid toward the right end surface of the filter screen 20 through the acid nozzle 61, thereby effectively dissolving the alkaline particulate impurities to form sewage. Then, the sewage pump 32 is started to discharge the current sewage through the sewage pipe 3;

[0040] The above operation realizes the step-by-step targeted spraying of the acidic particulate impurities and alkaline particulate impurities accumulated in the mesh of the filter 20, and effectively dissolves the corresponding alkaline or acidic cleaning liquid to form sewage. After cleaning, the sewage will be effectively discharged through the sewage pipe 3, avoiding the situation where the liquid cannot flow normally due to the blockage of the filter 20 during long-term use, thereby ensuring the normal use of the one-way valve body 1.

[0041] In addition, by providing an alkali liquid filling pipe 50 on the alkali liquid storage tank 5 and an acid liquid filling pipe 60 on the acid liquid storage tank 6, the alkali liquid storage tank 5 can be conveniently replenished with alkaline cleaning liquid, and the acid liquid storage tank 6 can also be conveniently replenished with acidic cleaning liquid.
