Description

Technical Field

[0001] The utility model belongs to the technical field of sewage discharge valves, in particular to a stop valve which is convenient for sewage discharge. Background Art

[0002] The stop valve, also known as the gate valve, is a forced sealing valve. The stop valve has small friction between the sealing surfaces during opening and closing, is relatively durable, has a small opening height, is easy to manufacture and maintain, and is suitable not only for medium and low pressures, but also for high pressures.

[0003] A Chinese patent with publication number CN218582251U discloses a sewage shut-off valve, including a shut-off valve body, both ends of which are provided with connecting pipes connected to the interior, a sedimentation box is provided on one of the connecting pipes, a filter box is provided in the sedimentation bin, a through groove is provided on the left side of the filter box, a filter screen is embedded in the right side of the filter box, threaded holes are provided near the corners in the annular groove, a sealing cover is provided above the annular groove, a sealing gasket is provided at the bottom of the sealing cover corresponding to the annular groove, a through hole is provided on the sealing cover corresponding to the threaded hole, and fastening bolts are provided in the through holes; the sewage shut-off valve is provided with a sedimentation box and installed on one of the connecting pipes, the connecting pipe is connected to the shut-off valve body, and the solution passing through is precipitated, intercepted and filtered under the action of the sedimentation box, reducing the influence of internal blockage on the shut-off valve body, the filter box is plugged into the sedimentation bin, which is convenient for taking out and replacing and cleaning the filter box, which is conducive to continuous interception.

[0004] In the current prior art, when some existing stop valves are discharging sewage, a sedimentation box is generally set at a certain position on the surface of the pipe to filter the sludge inside the sewage pipe to facilitate the subsequent sludge sewage discharge. This method can isolate most of the sludge, but there will still be a lot of relatively fine impurities passing through the filter net, thereby flowing inside the diversion pipe, and these fine sludges will be formed and adhered to the inner wall surface of the diversion pipe. As the sludge continues to accumulate, larger particles are formed, which are easy to cause blockage of the stop valve, and the intercepted and filtered dirt is not convenient for quick cleaning to facilitate the continuous use of the stop valve.

[0005] To this end, the utility model provides a stop valve which is convenient for draining sewage. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the utility model is a stop valve for facilitating sewage discharge, comprising a stop valve, a limit sealing unit movably sleeved on the outer surface of the stop valve, the limit sealing unit comprising a sealing strip, a water guide pipe and a docking limit strip, a water source differentiation impact unit is fixedly installed on the inner surface of the water guide pipe, the water source differentiation impact unit comprises a clamping ring, a differentiation guide tube and a guide convex groove, the filtered sewage is guided through the water guide pipe, and when the sewage flows into the inside of the clamping ring, the flowing sewage is lifted and compressed in cooperation with the guide convex groove.

[0008] Preferably, the outer surface of the clamping ring is fixedly connected to the inner wall surface of the water pipe, and the differentiation guide tube is positioned so as to be movably overlapped on the inner surface of the clamping ring.

[0009] Preferably, the guide groove is arranged on the inner surface of the clamping ring, and the outer surface of the guide groove is arranged on the outer surface of one end of the differentiation guide tube.

[0010] Preferably, the inner surfaces of the clamping ring and the differentiation guide tube are respectively fixedly connected with a triangular clamping sleeve, and a part of the water source will pass through the gap between the clamping ring and the differentiation guide tube, and the sewage will be diverted by utilizing the curvature on the outer surface of the differentiation guide tube. Since the water outlet port of the differentiation guide tube is a relatively large expansion port, the gap between the differentiation guide tube and the inner wall of the water guide tube is relatively small. When the water source flows, the flow path is compressed while the flow rate remains unchanged, which will accelerate the flow speed and impact force of the water source, so that a certain flow velocity difference is generated between the outer circle water source and the inner circle water source, and then some fine impurities that have just adhered to the inner wall of the water guide tube are washed off. The fine impurities will penetrate into the inner circle water source due to the flow velocity difference, and the fine impurities will be taken away with the flow of the water source, reducing the continuous adhesion of fine impurities to form large particles of impurities, and a limited clamping arm is movably sleeved on the inner surface of the triangular clamping sleeve.

[0011] Preferably, an extruded differentiation soft strip is fixedly connected to the outer surface of the differentiation guide tube, and the outer surface of the extruded differentiation soft strip is pressed against the inner wall of the water pipe, and the differentiation guide tube is suspended by multiple limiting clamping arms, so that a differentiation layer is formed between the differentiation guide tube and the inner surface of one end of the clamping ring, and the water source is differentiated into an inner layer and an outer layer.

[0012] Preferably, flanges are fixedly connected to the outer surfaces of both ends of the stop valve and the water pipe, respectively, and one end of the stop valve fits with one end of the water pipe.

[0013] Preferably, the butt-jointing limit strip is arranged on the outer surface of the flange, and the sealing strip is fixedly connected to the outer surface of the flange.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The utility model discloses a stop valve for sewage discharge, which diverts the filtered sewage through the water guide pipe. When the sewage flows into the inside of the clamping ring, the diversion convex groove is used to lift and compress the flowing sewage. A part of the water source will pass through the gap between the clamping ring and the differentiation guide cylinder, and the sewage will be diverted by the curvature on the outer surface of the differentiation guide cylinder. Since the outlet port of the differentiation guide cylinder is a relatively large expansion port, the gap between the differentiation guide cylinder and the inner wall of the water guide pipe is relatively small. When the water source flows, the flow path is compressed under the condition of unchanged flow rate, which will accelerate the flow speed and impact force of the water source, so that a certain flow rate difference is generated between the outer circle water source and the inner circle water source. After washing off some fine impurities that have just adhered to the inner wall of the water guide pipe, the fine impurities will penetrate into the inner circle water source due to the flow rate difference, and the fine impurities will be taken away with the flow of the water source, thereby reducing the continuous adhesion of fine impurities to form large particle impurities.

[0016] 2. The utility model describes a stop valve for easy sewage discharge. After the differentiation guide tube is replaced at a later stage, the limit clamping arm is clamped to the inside of the triangular clamping sleeve, and the differentiation guide tube is suspended by multiple limit clamping arms, so that the differentiation guide tube and the inner surface of one end of the clamping sleeve form a differentiation layer, which differentiates the water source into an inner circle layer and an outer circle layer.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figures 1 to 5 As shown, a stop valve for sewage discharge according to an embodiment of the utility model comprises a stop valve 11, a limit sealing unit is movably sleeved on the outer surface of the stop valve 11, the limit sealing unit comprises a sealing strip 15, a water pipe 12 and a docking limit strip 14, a water source differentiation impact unit is fixedly installed on the inner surface of the water pipe 12, the water source differentiation impact unit comprises a clamping ring 16, a differentiation guide tube a2 and a guide convex groove a1, the outer surface of the clamping ring 16 is fixedly connected to the inner wall surface of the water pipe 12, the differentiation guide tube a2 is movably overlapped on the inner surface of the clamping ring 16, and the guide tube a1 is fixedly connected to the inner surface of the clamping ring 16. The convex groove a1 is arranged on the inner surface of the clamping ring 16, and the filtered sewage is guided through the water guide pipe 12. When the sewage flows into the clamping ring 16, the flowing sewage is lifted and compressed by the guide convex groove a1, and the outer surface of the guide convex groove a1 is arranged on the outer surface of one end of the differentiation guide tube a2. The clamping ring 16 and the inner surface of the differentiation guide tube a2 are respectively fixedly connected with a triangular clamping shell a3. A part of the water source will pass through the gap between the clamping ring 16 and the differentiation guide tube a2, and the sewage will be guided by the curvature on the outer surface of the differentiation guide tube a2. Diversion, because the outlet port of the differentiation diversion tube a2 is a relatively large expansion port, the gap between the differentiation diversion tube a2 and the inner wall of the water guide pipe 12 is relatively small. When the water source is flowing, the flow path is compressed under the condition of constant flow rate, which will accelerate the flow speed and impact force of the water source, so that a certain flow rate difference is generated between the outer circle water source and the inner circle water source, and then some fine impurities just attached to the inner wall of the water guide pipe 12 are washed off. The fine impurities will penetrate into the inner circle water source due to the flow rate difference, and the fine impurities will be taken away with the flow of the water source, reducing the continuous adhesion of the fine impurities and the formation of To form large particles of impurities, a limiting clamping arm a4 is movably sleeved on the inner surface of the triangular clamping sleeve a3. After the differentiation guide tube a2 is replaced later, the limiting clamping arm a4 is clamped into the inside of the triangular clamping sleeve a3. An extruded differentiation soft strip a5 is fixedly connected to the outer surface of the differentiation guide tube a2, and the outer surface of the extruded differentiation soft strip a5 is pressed against the inner wall of the water guide pipe 12. A plurality of limiting clamping arms a4 are used to suspend the differentiation guide tube a2, so that the differentiation guide tube a2 and the inner surface of one end of the clamping ring 16 form a differentiation layer, and the water source is differentiated into an inner layer and an outer layer.

[0026] like Figures 1 to 5As shown, flanges 13 are fixedly connected to the outer surfaces of both ends of the stop valve 11 and the water pipe 12, respectively. One end of the stop valve 11 fits with one end of the water pipe 12. The position of the docking limit strip 14 is set on the outer surface of the flange 13. The position of the sealing strip 15 is fixedly connected to the outer surface of the flange 13. When the water pipe 12 is docked with the stop valve 11, the position of the stop valve 11 and the water pipe 12 is limited by the docking limit strip 14, and the sealing strip 15 is used to increase the sealing between the stop valve 11 and the water pipe 12.

[0027] Working principle: The filtered sewage is guided through the water pipe 12. When the sewage flows into the clamping ring 16, the diversion convex groove a1 is used to lift and compress the flowing sewage. A part of the water source will pass through the gap between the clamping ring 16 and the differentiation guide tube a2. The curvature on the outer surface of the differentiation guide tube a2 is used to guide the sewage. Since the outlet port of the differentiation guide tube a2 is a relatively large expansion port, the gap between the differentiation guide tube a2 and the inner wall of the water pipe 12 is relatively small. When the water source is flowing, the flow path is compressed under the condition of unchanged flow rate, which will accelerate the flow speed and impact force of the water source. A certain flow velocity difference is generated between the outer circle water source and the inner circle water source. After some fine impurities that have just adhered to the inner wall of the water pipe 12 are washed off, the fine impurities will penetrate into the inner circle water source due to the flow velocity difference, and the fine impurities will be taken away with the flow of the water source, reducing the continuous adhesion of fine impurities to form large particles of impurities. After the differentiation guide tube a2 is replaced in the later stage, the limit clamping arm a4 is clamped to the inside of the triangular clamping sleeve a3, and multiple limit clamping arms a4 are used to suspend the differentiation guide tube a2, so that the differentiation guide tube a2 and the inner surface of one end of the clamping ring 16 form a differentiation layer, and the water source is differentiated into an inner circle layer and an outer circle layer.
