Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, and relates to a dyeing monitoring device, in particular to a water inlet valve leak detection device for a dyeing machine and a dyeing equipment. Background Art

[0002] The dyeing machine is made of all stainless steel, and the mechanical speed regulation has the advantages of noiselessness and convenient speed regulation, and is suitable for dyeing operations of knitted or woven fabrics such as hemp, cotton, rayon, and blended fabrics.

[0003] At present, the water inlet valve of the dyeing machine is generally arranged on the main return pipe, and the water volume of the dyeing machine is filled in the form of flooding. During normal dyeing, the water inlet valve is closed to control a certain amount of water.

[0004] However, when the water inlet valve fails or leaks, excess water will enter the fuselage, further diluting the dye liquor, resulting in a decrease in the concentration of the dye liquor, or leakage of the dye liquor due to leakage of the main water inlet valve, causing the dye liquor to leak out. This will affect the dyeing quality, increase the defective rate, and cause economic losses. At present, no detection device for valve body leakage has been designed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a water inlet valve leak detection device for a dyeing machine and a dyeing equipment in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved by the following technical solutions: A water inlet valve leak detection device for a dyeing machine includes a dye vat and a main pump. The liquid pumping port of the main pump is connected to the dye vat through a main return pipeline. The main return pipeline is connected to a water inlet pipeline through a branch port. An inlet main valve is connected in series on the water inlet pipeline first, and then a leak detection component is connected in a branched manner. The ends of the water inlet pipeline are connected in parallel with a plurality of water inlet valves.

[0007] In the above-mentioned water inlet valve leak detection device for a dyeing machine, the leak detection component includes a leak detection pipe communicating with the water inlet pipeline. A leak detection valve is arranged at the end of the leak detection pipe, and an overflow elbow is connected to the leak detection valve.

[0008] In the above-mentioned water inlet valve leak detection device for a dyeing machine, the leak detection valve has an inlet and an outlet. The inlet is connected to the leak detection pipe, and the outlet is connected to the overflow elbow.

[0009] In the above-mentioned water inlet valve leak detection device for a dyeing machine, the leak detection valve specifically adopts a pneumatic Y-shaped valve. The leak detection pipe is arranged vertically, and the end of the leak detection pipe is the highest point of the pipe body.

[0010] In the above-mentioned water inlet valve leak detection device for a dyeing machine, the overflow elbow is an inverted U-shaped pipe, and the highest vertex of the inverted U-shaped pipe is higher than the horizontal plane where the water inlet valve is located.

[0011] In the above dyeing machine water inlet valve leak detection device, a control valve is connected in series on the main return pipeline.

[0012] In the above dyeing machine water inlet valve leak detection device, a drain pipeline branches out from the main return pipeline. The drain pipeline is a T-shaped pipeline. The vertical pipe of the T-shaped pipeline is connected to the main return pipeline, and drain valves are arranged at both ends of the horizontal pipe of the T-shaped pipeline.

[0013] In the above dyeing machine water inlet valve leak detection device, the drain pipeline is located on the main return pipeline between the dyeing vat and the control valve.

[0014] A dyeing device includes the above dyeing machine water inlet valve leak detection device.

[0015] Compared with the prior art, the present dyeing machine water inlet valve leak detection device and the dyeing device have the following beneficial effects:

[0016] 1. Real-time detection of valve leakage: By setting a leak detection component in the water inlet pipeline, this device can effectively detect the leakage of each valve. The leak detection component includes a leak detection pipe, a leak detection valve, and an overflow elbow. When the water inlet valve leaks, whether it is clear water leakage or dye liquor leakage, it can be discharged through the overflow elbow, so as to discover problems in time. This design ensures that during the operation of the dyeing machine, the leakage of any valve can be quickly detected and measures can be taken, reducing production losses caused by valve leakage.

[0017] 2. Precision control of the dye liquor flowing into the dyeing vat: The control valve on the main return pipeline enables the main pump to adjust and control the suction volume of the dye liquor at the return position of this pipeline. By adjusting the valve opening, the stacking state of the fabric during the operation in the dyeing vat can be achieved, thereby improving the stable operation of the fabric during the dyeing process, ensuring smoothness and enhancing the dyeing effect.

[0018] 3. Simplify the leak detection operation: When the equipment is operating normally, close all water inlet valves and the main water inlet valve. After opening the leak detection valve, the leakage of any valve can be quickly detected through the leak detection valve and the overflow elbow. This simplified operation process makes the leak detection process more efficient, reduces operation complexity, and is convenient for maintenance personnel to check and repair.

[0019] 4. Improve the safety and stability of the system: This device ensures the safety and stability of the dyeing system during operation through careful design. The existence of the leak detection function greatly reduces the potential risks caused by equipment failures. At the same time, the setting of the drain pipeline and the overflow elbow also improves the system's ability to handle abnormal situations.

[0020] Generally speaking, through a number of innovative designs, this device not only improves the operation efficiency and detection accuracy of the dyeing machine, but also greatly enhances the safety and stability of the equipment, having significant practical application value.

Specific Embodiments

[0024] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0025] As Figures 1 to 2 shown, the water inlet valve leak detection device of this dyeing machine includes a dye vat 1 and a main pump 2. The liquid pumping port of the main pump 2 is connected to the dye vat 1 through the main return pipeline 3. The main return pipeline 3 is connected to the water inlet pipeline 4 through a branch port. The water inlet pipeline 4 is first connected in series with the main water inlet valve 5 and then branched to connect to the leak detection assembly. The ends of the water inlet pipeline 4 are connected in parallel with several water inlet valves.

[0026] On the water inlet pipeline 4, the main water inlet valve 5 is closer to the branch port, so as to finally control the water to enter the dye vat 1 through the main water inlet valve 5. The several water inlet valves specifically include a water inlet valve 1 9, a water inlet valve 2 10 and a water inlet valve 3 11, and each water inlet valve individually controls a water supply pipeline.

[0027] As Figure 2 shown, the leak detection assembly includes a leak detection pipe 6 communicating with the water inlet pipeline 4. The end of the leak detection pipe 6 is provided with a leak detection valve 7, and an overflow elbow 8 is connected to the leak detection valve 7. The leak detection valve 7 has an inlet and an outlet. The inlet is connected to the leak detection pipe 6, and the outlet is connected to the overflow elbow 8. The leak detection valve 7 specifically adopts a pneumatic Y-shaped valve. The leak detection pipe 6 is vertically arranged, and the end of the leak detection pipe 6 is the highest point of the pipe body.

[0028] During the dyeing operation process, the main water inlet valve 5 and each water inlet valve are all in the closed state. Whether the main water inlet valve 5 or a certain water inlet valve leaks, the liquid flow will flow into the water inlet pipeline 4 and the leak detection pipe 6, and then flow out through the leak detection valve 7 and the overflow elbow 8, so as to discover the valve body leakage problem.

[0029] The overflow elbow 8 is an inverted U-shaped pipe, and the highest vertex of the inverted U-shaped pipe is higher than the horizontal plane where the water inlet valve is located. One downward port of the inverted U-shaped pipe is connected to the outlet of the leak detection valve 7, and the other downward port of the inverted U-shaped pipe communicates with the outside. The horizontal pipe section of the inverted U-shaped pipe is higher than all the water inlet valves, so that when the water inlet valves supply water, the main water inlet valve 5 is opened at the same time, so the water flow cannot overflow from the inverted U-shaped pipe.

[0030] A drain pipe 13 branches out from the main return pipe 3. The drain pipe 13 is a T-shaped pipe. The vertical pipe of the T-shaped pipe communicates with the main return pipe 3, and drain valves 14 are arranged at both ends of the horizontal pipe of the T-shaped pipe.

[0031] The drain pipe 13 is on the main return pipe 3 between the dyeing vat 1 and the control valve 12. The drain pipe 13 is arranged close to the dyeing vat 1.

[0032] The operation mode of the water inlet valve leak detection device of this dyeing machine:

[0033] When the dyeing vat 1 needs to be filled with water, the main water inlet valve 5 and at least one water inlet valve are opened, and at the same time the leak detection valve 7 is closed. The clear water passes through the water inlet pipe 4, the main water inlet valve 5, and the main return pipe 3 from the water inlet valve and flows into the dyeing vat 1.

[0034] When the equipment is operating normally, the main water inlet valve 5 and all the water inlet valves are closed, and at the same time the leak detection valve 7 is opened. If the water inlet valve leaks, since the main water inlet valve 5 is in the closed state at this time, the clear water flows from the leaking water inlet valve into the water inlet pipe 4, passes through the leak detection valve 7, and clear water flows out from the overflow elbow 8, so it can be known that the water inlet valve leaks. If the main water inlet valve 5 leaks, the colored dye liquor in the dyeing vat 1 flows into the water inlet pipe 4 through the main water inlet valve 5, passes through the leak detection valve 7, and colored liquid flows out from the overflow elbow 8, then it can be known that the main water inlet valve 5 leaks.
