Description

Technical Field

[0001] This application relates to the technical field of wire harness sealing for valve bodies, and particularly to a wire harness limiting and sealing structure. Background Art

[0002] In modern buildings and industrial facilities, it is crucial to ensure the safety and reliability of the water supply system for the temperature and pressure detection valves in the water supply pipeline. The water supply system usually contains a complex pipeline network, which is responsible for transporting water to various usage points. To maintain the normal operation of the system and prevent potential safety hazards, temperature and pressure detection valves are widely used in water supply systems of various scales. The temperature and pressure detection valve can monitor the water temperature in the pipeline in real time, ensure that the water temperature is within a safe range, and avoid equipment damage or safety accidents caused by high or low temperatures; it can also detect the pressure changes in the water supply pipeline, and the temperature and pressure detection valve can adjust the valve opening in a timely manner to maintain a stable water supply pressure and prevent pipe bursts or other failures caused by excessive pressure. For industrial production lines that require stable water supply conditions, the temperature and pressure detection valve is one of the indispensable safety devices, and it plays a crucial role in ensuring the safety and stability of the water supply system.

[0003] These detection valves are usually equipped with power supply wire harnesses and data transmission wire harnesses to achieve remote monitoring and automatic control. However, there are some deficiencies in the existing detection valve designs, especially in the wire harness connection part; the detection valves usually need to fix the power supply wire harness or data transmission wire harness by clamping; in the actual application process, if these wire harnesses are pulled by external forces, it is very easy to cause circuit breakage problems, affecting the functions of the detection valves; in addition, if there is no appropriate positioning structure to protect the wire harness, once the wire harness is pulled, it may damage the internal sealing of the detection valve. If the detection valve is installed outdoors or in a humid environment and there is a lack of sufficient waterproof measures after the sealing is damaged, it may directly damage the internal structure of the detection valve in case of immersion or rain, seriously affecting its service life and reliability. Content of the Utility Model

[0004] This device provides a wire harness limiting and sealing structure, and the specific implementation is as follows:

[0005] A wire harness limiting and sealing structure includes:

[0006] A vertical through groove provided in the valve seat, and the vertical through groove is used for guiding the wire harness outwards;

[0007] A wire fixing claw sleeved on the wire harness, the wire fixing claw is sleeved in the vertical through groove, a sealing ring is installed between the two, and a clamping structure for preventing the bottom from falling off is formed between the wire fixing claw and the vertical through groove. The top of the wire fixing claw abuts against the pressing plate of the internal detection structure of the valve seat. The wire harness is prevented from being pulled up and down by the clamping structure and the pressing plate, and the sealing ring provides a sealing effect for it.

[0008] Preferably, the vertical through groove is provided with a conical wall, the inner diameter of its inner edge is larger than the outer diameter of its outer edge, and the wire fixing claw is provided with a conical cylinder part matching its contour.

[0009] Based on the above technical solution, by arranging a wire fixing claw with a conical cylinder part on the wire harness, and this claw cooperating with the conical wall in the detection valve body, the sealing performance at the connection of the wire harness can be significantly improved; when the wire harness is pulled by an external force, the contact area between the conical cylinder part and the conical wall will gradually increase, thereby strengthening the sealing performance between the two, and preventing the sealing failure caused by the movement of the wire harness; this improvement not only reduces the risk of wire harness open circuit, but also enhances the overall waterproof performance of the detection valve, and it will not be easily damaged even in a harsh environment, ensuring the normal operation of the detection valve. Even after long-term use or experiencing multiple plugging and unplugging operations, the detection valve can still maintain good sealing performance.

[0010] Preferably, a claw part with a movable gap is formed along the circumferential direction at the narrow diameter end of the conical cylinder part.

[0011] Preferably, inner claws are formed along the circumferential direction of the claw part, and the inner claws abut against the circumferential side of the wire harness.

[0012] Based on the above technical solution, inner claws are arranged inside the wire fixing claw, and these inner claws can tightly hold the wire harness. When the wire harness is pulled by an external force, the inner claws will generate a stronger grasping force on the wire harness; when the wire harness is pulled, the inner claws will further tighten, thereby strengthening the contact between the claw part and the wire harness, improving the sealing performance, and preventing the sealing failure caused by the movement of the wire harness. This design not only reduces the risk of wire harness open circuit, but also enhances the overall waterproof performance of the detection valve, and it will not be easily damaged even in a harsh environment.

[0013] Preferably, a stepped layer is formed between the inner claw and the end of the claw part, and the stepped layer is used for clamping the sealing ring.

[0014] Preferably, the inner diameter of the opening at the bottom of the valve seat is smaller than the minimum inner diameter of the conical wall, and the upper and lower ends of the sealing ring respectively abut against the bottom of the claw part and the top of the opening.

[0015] Based on the above technical solution, by arranging a stepped layer structure between the inner claw and the claw part, this structure can effectively accommodate the top of the sealing ring therein, which not only plays a limiting role, but also improves the integrity of the sealing structure; the top of the sealing ring is accommodated in the stepped layer structure, which can effectively prevent the sealing ring from shifting or falling off when the wire harness is pulled, and further enhances the overall sealing performance.

[0016] Preferably, the wire harness is divided into an adjacent long straight segment and a coiled segment, the coiled segment is correspondingly arranged outside the valve seat, and the long straight segment is used for installing the wire fixing claw.

[0017] Based on the above technical solution, by applying a wire harness with coiled line segments, the scalability of the wire harness can be improved, and the situation of directly pulling the wire harness is avoided; the coiled line segments allow the wire harness to freely stretch and contract within a certain range. In this way, even if the external environment changes or the wire harness is slightly pulled, the tension can be relieved through the stretching and contraction of the coiled line segments, and the wire harness is prevented from directly bearing excessive tension.

[0018] Preferably, an open slot is provided at the position corresponding to the vertical through slot on the pressing plate, and the inner spacing of the open slot is greater than the diameter of the long straight line segment and less than the maximum inner diameter of the wire fixing claw.

[0019] Based on the above technical solution, by using the base for installing the detection structure in the detection valve as the pressing plate, no new components need to be added. It cooperates with the conical wall to achieve the vertical upper and lower limits of the wire fixing claw. This design ensures that the wire harness will also be pushed upward during subsequent use, thereby further enhancing the stability of the wire harness and further avoiding the damage to the sealing performance caused by vertical movement.

[0020] In summary, the present application includes the following beneficial technical effects:

[0021] 1. By providing a wire fixing claw with a conical barrel part on the wire harness in the present utility model, which cooperates with the conical wall, the sealing performance between the two becomes stronger when the wire harness is pulled, and the situation of sealing failure will not occur;

[0022] 2. By setting the staggered layer between the inner claw and the claw part in the present utility model, the top of the sealing ring is beneficially accommodated therein, which can not only play a limiting role but also improve the integrity of the sealing structure;

[0023] 3. The structure of the present utility model is simple. By borrowing the pressing plate left by the detection structure installation and cooperating with the conical wall to achieve the vertical limit of the wire fixing claw, the wire harness cannot be pushed upward during subsequent use and affect its sealing performance.
