A good water injection regulating valve can automatically complete underground water injection according to the set injection volume. It eliminates the error of manual valve control by oil workers, ensures the accuracy of underground water injection, and frees operators from boring work, making it easier to realize unmanned operation in the water injection room. The welding accuracy and strength of the water injection regulating valve directly affect the life and safety of the water injection system, and are related to the output efficiency of crude oil.

[0003] In the prior art, first, the parts of the water-injection regulating valve are prepared and placed in the welding area. They are arranged in the order of flange, conduit, valve body, conduit, and flange, and placed on the boss. The outer side of the flange is leveled with a pressure block to prepare for spot welding positioning. This method has the following defects for product spot welding positioning: (1) It relies on human eyes and tape measures to control the length of the product using the boss and pressure block. This error is relatively large, resulting in the water-injection regulating valve having different lengths after welding, affecting the consistency of the product. (2) The spot welding of the horizontal conduit and the vertical flange is affected by the tooling and welding stress, resulting in the tilting of the flange and the conduit, which affects both the aesthetics and the precision of the product. (3) A set of tooling can only correspond to the spot welding of one product. The spot welding of different products requires switching tooling back and forth for leveling.

[0008] Furthermore, the displacement adjustment assembly includes a movable nut, a screw rod and a hand wheel; The screw is arranged in the displacement adjustment hole, and one end thereof penetrates the displacement adjustment hole and extends to the outside of the side plate, and the hand wheel is assembled at the end of the screw extending to the outside of the side plate; The movable nut is located in the displacement adjustment hole and is threadedly connected to the screw rod.

[0014] In a second aspect, the present invention further provides a method for using a water-injection regulating valve positioning spot welding device, based on the above-mentioned water-injection regulating valve positioning spot welding device, comprising the following steps: The rigid plate is mounted on the displacement adjustment and measurement assembly, wherein the two ends of the bottom of the rigid plate are respectively fixedly connected to the two sides of the displacement adjustment and measurement assembly, and the end of the rigid plate is located at the zero scale line of the scale line, and the two ends of the bottom of the movable plate are respectively fixed to the displacement adjustment and measurement assembly through the displacement adjustment assembly, and the spacing between the movable plate and the rigid plate can be adjusted through the displacement adjustment assembly; The two ends of the water-injection regulating valve assembly are respectively placed on the stationary plate and the movable plate, and are connected by magnetic fixation. The welding gun is aimed at the ends of the water-injection regulating valve assembly to perform positioning spot welding.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides a water-injection regulating valve positioning spot welding device, wherein a displacement adjustment component enables a movable plate to move on a displacement adjustment measuring component, so that the movable plate can be adjusted according to water-injection regulating valve components of different sizes or different welding requirements, thereby increasing the flexibility and versatility of the device and enabling it to be applicable to water-injection regulating valve components of various specifications and models. The welding head of the welding gun is aligned with the end of the water-injection regulating valve component, and electric welding operation can be directly performed. Due to the precise adjustment of the movable plate and the rigid plate, and the use of magnetic fixed connection, the welding process can be more stable and efficient. This helps to improve production efficiency and reduce errors and defective product rates during welding. The displacement adjustment measuring component in the device is designed with scale lines, and the rigid plate is located at the zero scale line of the scale lines, so that the spacing adjustment between the movable plate and the rigid plate becomes very intuitive and accurate. The user can easily adjust the position of the movable plate by observing the scale lines to meet the requirements for precise welding of the two ends of the water-injection regulating valve component. The present invention helps to improve the welding quality and overall performance of the water-injection regulating valve component. Stable welding can ensure the sealing and durability of the valve component, thereby improving its reliability and service life in practical applications.

[0016] Furthermore, the vertical fixation of the base and two sets of side panels provides a solid foundation for the entire displacement adjustment measurement assembly. By opening displacement adjustment holes on the side panels and setting displacement adjustment assemblies, precise adjustment of the position of the moving plate can be achieved, so that the user can easily adjust the spacing between the moving plate and the solid plate as needed, thereby meeting the welding requirements of water-injected regulating valve assemblies of different sizes or different welding requirements. The scale lines are located below the solid plate mounting holes and the displacement adjustment holes, and the two ends of the bottom of the solid plate are located at the zero scale lines of the scale lines, so that the user can intuitively understand the spacing between the moving plate and the solid plate by observing the scale lines, thereby more accurately controlling the welding position. A gasket is provided between the fixed end of the solid plate and the side panel to further increase the stability and firmness of the solid plate.

[0017] Furthermore, the positions of the rigid plate mounting holes and the displacement adjustment holes correspond and are of equal height, which can ensure that the rigid plate and the movable plate remain parallel during installation, and at the same time ensure that the two ends of the water-injection regulating valve assembly are in the correct position during welding, thereby improving the accuracy and quality of welding.

[0018] Furthermore, by rotating the hand wheel, the displacement of the movable nut on the screw rod can be precisely controlled, so that the movable plate fixed on the movable nut can be displaced, thereby achieving fine adjustment of the position of the movable plate. The threaded connection between the movable nut and the screw rod provides a stable connection structure, which can ensure that the movable plate will not move due to vibration or external force during the adjustment process.

[0019] Furthermore, the magnetic plate can ensure the position accuracy of the water-adjusting valve assembly during assembly, because the magnetic force automatically attracts the assembly to the correct position. This helps reduce the risk of performance problems or leakage caused by assembly errors. The magnetic switch set on the moving plate can sense the state change of the magnetic connection. When the water-adjusting valve assembly establishes a magnetic connection with the moving plate, the magnetic switch triggers the corresponding circuit or signal, thereby achieving a stable connection between the water-adjusting valve assembly and the fixed plate and the moving plate.

[0020] Furthermore, the placement slot provides a precise placement position for the water-adjusting valve assembly, ensuring the stability and accuracy of the valve assembly before welding. The combination of the positioning hole and the positioning pin further enhances the fixing effect of the valve assembly and prevents movement caused by vibration or external force during welding. By directly placing the valve assembly in the placement slot and fixing it with the positioning pin, the operation process is simplified. Users can easily complete the positioning and fixing of the valve assembly without using complex fixtures or additional fixing devices.

[0021] Furthermore, the equal depth of the placement grooves means that the support points of the water-adjusting valve assembly on the fixed plate and the movable plate are at the same height. This helps to ensure the levelness and stability of the valve assembly before welding and avoid welding errors caused by uneven support points.

[0022] Furthermore, the valve body is arranged on the conduit and communicated with the conduit, and the two ends of the conduit respectively pass through two sets of flanges and are clamped on the rigid plate and the movable plate. This structure makes the overall structure of the water-mixing regulating valve assembly compact and stable. The close connection between the flange and the conduit helps prevent leakage and ensure the sealing performance of the valve. The two ends of the conduit are directly arranged in the placement groove and clamped on the rigid plate and the movable plate through the flange. This design simplifies the assembly process. At the same time, the welding head of the welding gun can be directly aligned with the connection between the flange and the conduit for welding, without the need for additional positioning or adjustment steps, thereby improving welding efficiency and accuracy.

[0023] Furthermore, the corresponding design of the through holes and the positioning holes, as well as the use of positioning pins, ensure the precise positioning between the flange and the rigid plate and the movable plate, which is not only stable and reliable, but also can prevent movement caused by vibration or external force during welding, thereby ensuring the accuracy and quality of welding.

[0024] The present invention also provides a method for using a water-injection regulating valve positioning spot welding device. By setting a solid plate on a displacement adjustment measuring assembly and ensuring that the end of the solid plate is at the zero scale line of the scale line, the position of the solid plate can be accurately controlled. The spacing between the movable plate and the solid plate is adjusted by the displacement adjustment assembly, thereby achieving accurate control of the positions of both ends of the water-injection regulating valve assembly. This high-precision positioning and measurement method helps to improve the accuracy and quality of welding. The design of the displacement adjustment assembly allows the spacing between the movable plate and the solid plate to be flexibly adjusted. This flexibility enables the device to be applicable to water-injection regulating valve assemblies of different sizes and specifications, thereby enhancing the versatility and adaptability of the equipment. The method for using the present invention is concise and clear. The user only needs to set up the solid plate on the displacement adjustment measuring assembly according to the steps, adjust the spacing between the movable plate and the solid plate, and then place the water-injection regulating valve assembly on the solid plate and the movable plate to perform positioning spot welding. This simplified operation process reduces the difficulty of operation and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
