Abstract
Description
Technical Field
[0001] This utility model relates to the field of water jet loom technology, and more specifically, to a water-saving nozzle for water jet looms. Background Technology
[0002] Water jet looms use nozzles to spray water, which creates frictional traction on the weft yarn, causing it to fly through the warp yarns and thus completing the weft insertion operation. During the operation of a water jet loom, the nozzle is one of the key components for weft insertion, and its performance directly affects the weft insertion effect.
[0003] The water flow pattern and distribution of traditional nozzles are not uniform enough. To ensure the flight stability of the weft yarn, it is often necessary to increase the water pressure and spray volume. In addition, traditional nozzles perform intermittent weft insertion operations by quickly starting and stopping. However, some of the water flow from the nozzle does not fully act on the weft yarn and is lost in the surrounding environment. Furthermore, when the nozzle stops quickly, some water will still flow out of the nozzle due to inertia, resulting in a waste of resources.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water-saving nozzle for water-jet looms.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water-saving nozzle for a water-jet loom, comprising a nozzle body, the nozzle body comprising a core, a flow guiding shell, and a recovery shell, the flow guiding shell comprising a connecting part one, a flow guiding part one, a liquid inlet part, and a connecting part two, the core comprising a rotating part, a connecting part three, a flow guiding part two, and a yarn outlet part, the connecting part three being threadedly connected to the connecting part one, a pressurizing chamber being formed between the flow guiding part one and the flow guiding part two, the yarn outlet part extending into the connecting part two, a plurality of flow guiding plates being arranged in a circular array inside the connecting part two, the recovery shell comprising a connecting part four, a recovery part, and a liquid outlet part, the connecting part two being threadedly connected to the connecting part four, and a trimming part being fixedly connected to the inner wall of the end of the recovery part away from the connecting part two.
[0007] The present invention is further configured such that: the liquid inlet and the flow guide are interconnected, the outer peripheral wall of the liquid inlet is threadedly connected to a flow regulating valve, and the end of the flow regulating valve away from the liquid inlet is connected to a liquid inlet pipe.
[0008] The present invention is further configured such that: the inner diameter of the recovery part is larger than the inner diameter of the connecting part two; the length of the connecting part two is the same as the length of the connecting part four; the recovery part and the liquid outlet part are interconnected; and the liquid outlet part is connected to a liquid outlet pipe.
[0009] The present invention is further configured such that: both the pressurizing chamber and the recovery section are interconnected with the second connecting section, and the inner diameter of the second connecting section is smaller than the inner diameter of the trimming section.
[0010] The present invention is further configured such that the inner diameters of the rotating part and the connecting part are the same and fixedly connected, and the outer peripheral wall of the rotating part is a regular hexagon.
[0011] The present invention is further configured such that: the inner diameter of the first flow guide is greater than the outer diameter of the second flow guide; the first flow guide and the second flow guide have the same length; the outer diameter of the yarn outlet is smaller than the inner diameter of the second connecting part; and the length of the yarn outlet is smaller than the length of the flow guide plate.
[0012] In summary, this utility model has the following beneficial effects: by recycling the outer shell, it can collect the water flow that flows out due to inertia when the nozzle stops intermittently, as well as the water flow outside the sprayed water column, and collect it into the water storage tank through the liquid outlet pipe, thereby reducing resource waste. When the water flow in the pressurization chamber converges into the second connecting part, it will be affected by several circular array guide plates and transported in the same direction to form a stable water column, ensuring the flight stability of the weft yarn. It can appropriately reduce the water pressure and spray volume, further reducing resource consumption. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0018] Example: Water-saving nozzles for water-jet looms, such as... Figures 1-3As shown, the nozzle includes a nozzle body 1, which comprises a core 2, a flow guide shell 3, and a recovery shell 4. The core 2, flow guide shell 3, and recovery shell 4 are all made of stainless steel, possessing high strength and corrosion resistance, and maintaining structural stability during high-frequency operation. The flow guide shell 3 consists of a connecting part 301, a flow guide part 302, a liquid inlet part 303, and a connecting part 204. The core 2 consists of a rotating part 201, a connecting part 302, a flow guide part 203, and a yarn outlet part 204. 201. The inner diameter of the connecting part 3 202 is the same and fixedly connected. The outer peripheral wall of the rotating part 201 is a regular hexagon. By rotating the rotating part 201 with a wrench, the connecting part 3 202 can be threaded into the connecting part 1 301. Before threading, waterproof tape is wrapped around the external thread to ensure the sealing after connection. The inner diameter of the flow guide part 1 302 is larger than the outer diameter of the flow guide part 2 203. The lengths of the flow guide part 1 302 and the flow guide part 2 203 are the same, so that a pressure chamber 5 is formed between the flow guide part 1 302 and the flow guide part 2 203.
[0019] like Figures 1-3 As shown, the liquid inlet 303 and the flow guide 302 are interconnected. A flow regulating valve 7 is threadedly connected to the outer peripheral wall of the liquid inlet 303. The threaded connection is sealed with waterproof tape. The end of the flow regulating valve 7 away from the liquid inlet 303 is connected to an inlet pipe 8. The end of the inlet pipe 8 away from the flow regulating valve 7 is connected to a liquid supply system. The industrial system includes a water pump, controller, pressure regulating device, and water tank. The flow rate entering the pressurization chamber 5 can be adjusted by rotating the flow regulating valve 7. After entering the pressurization chamber 5, the water flow will be squeezed against each other for secondary pressurization, thereby increasing the flow velocity and kinetic energy of the liquid. At the same time, a water column with a corresponding cross-sectional shape is ejected according to the inner diameter shape of the connecting part 304. The water column is directed against the weft yarn. Frictional traction is generated, causing the weft yarn to fly through the warp yarn, thus completing the weft insertion operation. The yarn exit section 204 extends into the connecting section 2 304, causing the water flow to move along the yarn transport direction, preventing the water flow from moving in the opposite direction and entering the core 2. The connecting section 2 304 is provided with several guide plates 6 arranged in a circular array inside. The outer diameter of the yarn exit section 204 is smaller than the inner diameter of the connecting section 2 304, and the length of the yarn exit section 204 is smaller than the length of the guide plates 6. When the water flow in the pressurized chamber 5 converges into the connecting section 2 304, it will be affected by the several circular array of guide plates 6 and transported in the same direction to form a stable water column, thus ensuring the flight stability of the weft yarn. Therefore, the inlet flow rate can be appropriately reduced by the flow regulating valve 7, reducing resource consumption.
[0020] like Figures 1-3As shown, the recovery shell 4 consists of a connecting part 401, a recovery part 402, and a liquid outlet 403. A connecting part 304 is threaded into the connecting part 401, and the threaded connection is sealed with waterproof tape. The inner diameter of the recovery part 402 is larger than the inner diameter of the connecting part 304, and the length of the connecting part 304 is the same as the length of the connecting part 401. The pressurization chamber 5 and the recovery part 402 are both connected to the connecting part 304, so that when the water spraying operation stops, some of the water flowing out from the connecting part 304 due to inertia will converge at the bottom of the recovery part 402. The recovery part 402 is connected to the liquid outlet 403, which is connected to a liquid outlet pipe 9. The connection points at both ends of the liquid outlet pipe 9 and the liquid inlet pipe 8 are... The nozzle is secured with a snap-lock mechanism to prevent leakage. The end of the outlet pipe 9 away from the outlet section 403 is connected to the water storage tank, allowing the water collected in the recovery section 402 to be recycled back into the water storage tank for reuse, thus reducing resource waste. A trimming section is fixedly connected to the inner wall of the end of the recovery section 402 away from the connecting section 304. The inner diameter of the connecting section 304 is smaller than the inner diameter of the trimming section. This ensures that while maintaining the water column diameter, some water dispersed around the water column is separated by the inclined surface of the trimming section and collected in the recovery section 402, further reducing resource waste. This allows the nozzle to reduce water consumption during use, while ensuring a uniform and stable water column, thus guaranteeing a good weft insertion effect.
[0021] Working principle: The weft yarn enters from the core 2 and exits from the recovery shell 4. The pressure regulating device can control the water pressure during water flow. The water flow entering the pressurizing chamber 5 will squeeze each other to increase the pressure again, thereby increasing the flow speed and kinetic energy of the liquid. The water column, which forms a corresponding cross-sectional shape according to the inner diameter of the connecting part 2 304, is sprayed out from the yarn outlet 204. The water column generates a frictional traction force on the weft yarn, causing the weft yarn to fly in the warp yarn, thereby completing the weft insertion operation. When the water flow in the pressurizing chamber 5 converges into the connecting part 2 304, it is affected by several circular array guide plates 6 and is transported in the same direction to form a stable water column. When the water spraying operation stops, due to inertia, part of the water flow flowing out from the connecting part 2 304 will converge at the bottom of the recovery part 402. Part of the water flow dispersed around the water column will be separated by the inclined surface of the trimming part and converge at the bottom of the recovery part 402. The water flow collected in the recovery part 402 can be recycled into the water storage tank for secondary use through the liquid outlet pipe 9.

All technical solutions falling within the scope of this utility model's concept are protected.
