[0025] As Figures 1 to 5As shown, a kind of direct-buried welded valve valve well, including valve well body 1, two first connecting blocks 4 are connected on valve well body 1, second connecting block 5 is rotatably connected between the two first connecting blocks 4, well lid 6 is connected on second connecting block 5, receiving groove 10 is opened in well lid 6, fixed block 11 is fixedly installed in receiving groove 10, handle 12 is rotatably installed on fixed block 11, cover body 13 is installed above handle 12, rotating shaft 14 is installed in cover body 13, stirring block 15 is rotatably installed on rotating shaft 14, two springs 18 are connected on the bottom of stirring block 15, the end of the two springs 18 is connected on cover body 13, clamping groove 16 is opened in well lid 6, pressure sensor 17 is installed in well lid 6.In the present setting, valve well body 1 is the basic structure of the whole device, provides installation space for valve, accommodate and protect pipeline 3 and other internal components simultaneously, it bears the pressure from above, and cooperates with well lid 6, ensure the stability and sealing property of valve well internal environment, first connecting block 4 and second connecting block 5 jointly constitute the rotary connection structure of well lid 6, first connecting block 4 is fixed on valve well body 1, second connecting block 5 connects well lid 6, so that well lid can rotate around connecting point, facilitate opening and closing, so as to facilitate staff to enter valve well interior and operate, well lid 6 mainly plays the role of covering and protecting the interior of valve well, it prevents the direct contact of outside sundries, personnel etc. with valve 2 and pipeline 3 in valve well interior, and can also resist certain degree of external force impact, ensure the safety of valve well interior, receiving groove 10 is used for receiving handle 12, handle 12 is hidden in receiving groove 10 when well lid 6 is closed, avoid its damage or accidental touch by outside factors, fixed block 11 is used for installing handle 12, so that it can rotate in receiving groove 10, facilitate the opening of well lid 6, cover body 13 covers above handle 12, plays the role of protecting handle 12, in normal state, cover body 13 can prevent unauthorized personnel from easily contacting handle 12, only when stirring block 15 is unlocked, cover body 13 can be opened, so as to further improve the safety of valve well, rotating shaft 14 provides rotation center for stirring block 15, so that stirring block 15 can rotate around it, stirring block 15 is the locking key component of well lid 6, its end is clamped in clamping groove 16, realize the locking of well lid 6, when it is needed to open well lid, stirring block 15 is stirred to rotate around rotating shaft 14, so that it is separated from clamping groove 16, thus the locking state is released, pressure sensor 17 is a kind of intelligent monitoring element, when stirring block 15 is separated from clamping groove 16 and presses on pressure sensor 17, pressure sensor 17 can perceive pressure change, and convert this signal into electric signal, send prompt information to staff through wireless communication module, so as to realize the real-time monitoring of valve well opening state, spring 18 is connected between the bottom of stirring block 15 and cover body 13, plays the role of reset and auxiliary locking.

[0026] As Figures 1 to 5As shown in the specific embodiment, the valve well body 1 is provided with an installation groove 8, and a sealing ring 9 is installed in the installation groove 8. In this configuration, the installation groove 8 provides an installation position for the sealing ring 9.

[0027] like Figures 1 to 5 As shown, the card slot 16 and the storage slot 10 are interconnected. In this configuration, the interconnection between the card slot 16 and the storage slot 10 ensures that the lever 15 can rotate smoothly.

[0028] like Figures 1 to 5 As shown, spring 18 is made of stainless steel. In this setup, spring 18 always generates tension, and the use of stainless steel helps prevent rainwater corrosion, thereby increasing its service life.

[0029] like Figures 1 to 5 As shown, a sealing protrusion 7 is installed on the manhole cover 6, and the sealing protrusion 7 fits tightly with the sealing ring 9. In this configuration, the sealing protrusion 7 and the sealing ring 9 ensure that the manhole cover 6 can be opened and closed smoothly, preventing jamming, and also serve to seal the valve well. They are key components for ensuring that the inside of the valve well is dry and clean.

[0030] like Figures 1 to 5 As shown, the end of the lever 15 is engaged in the slot 16. In this configuration, the end of the lever 15 being engaged in the slot 16 ensures that the cover 13 remains closed at all times.

[0031] like Figures 1 to 5 As shown, valve 2 is installed in valve well body 1, and pipes 3 are connected to both ends of valve 2. In this setup, valve 2 is the core component of valve well, used to control the flow of fluids such as water and gas in pipe 3. By opening or closing valve 2, operations on the underground pipeline system can be performed, such as regulating flow, cutting off supply, and providing the necessary conditions for maintenance and other operations.

[0032] The implementation principle of a valve well for directly buried welded valves in this embodiment is as follows: When professional workers need to open the well cover due to pipeline operation needs, such as adjusting water flow or air pressure, or performing maintenance work, they need to follow a specific procedure. First, the workers need to move the lever 15 so that it rotates counterclockwise around the rotating axis 14 (towards...). Figure 5In this process, the engagement state between the dial block 15 and the card slot 16 is gradually released, and as the dial block 15 continues to rotate, it will slowly come off the card slot 16. When the dial block 15 completely comes off the card slot 16, the dial block 15 will press on the pressure sensor 17. The pressure sensor 17, as the intelligent monitoring element of the entire system, will immediately trigger the internal circuit to convert the pressure signal into an electrical signal and send a prompt message to the staff's handheld terminal (such as a mobile phone, tablet computer, etc.) through the pre-set wireless communication module. This prompt message is presented in the form of a prominent pop-up window, vibration or sound alarm, etc. to ensure that the staff can first perceive that the valve well is about to be opened, so as to timely prepare relevant work, such as on-site safety protection, operation process confirmation, etc. After the dial block 15 comes off the card slot 16, the staff can easily open the cover 13. At this time, the handle 12 hidden in the storage slot 10 is completely exposed. The staff only needs to hold the handle 12 and pull it up with force to quickly and smoothly open the well cover 6 by means of the rotating connection structure between the first connecting block 4 and the second connecting block 5, and then enter the inside of the valve well for subsequent operation. After the work is completed, the staff first puts the well cover 6 back to the original position, so that the sealing protrusion 7 tightly fits with the sealing ring 9 to ensure good sealing performance. Then, the handle 12 is stored in the storage slot 10, the cover 13 is closed, and the safety protection state of the valve well is restored.
