DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Specific embodiments are given below.

[0024] Such as Figures 1 to 4As shown in the figure, a fluorine-lined valve with anti-leakage function according to an embodiment of the present invention includes a warehouse connecting pipe 2 and a connecting pipe 3; the end of the warehouse connecting pipe 2 is fixedly connected to a control warehouse 1, and the warehouse connecting pipe 2 and the connecting pipe 3 are symmetrically arranged on both sides of the control warehouse 1; the ends of the warehouse connecting pipe 2 and the connecting pipe 3 are fixedly connected to a connecting disk 8; the ends of the warehouse connecting pipe 2 and the connecting pipe 3 are provided with a first pipe connection groove 4; a spring 7 is fixedly connected inside the first pipe connection groove 4 at the end of the warehouse connecting pipe 2, and the end of the spring 7 away from the warehouse connecting pipe 2 is fixedly connected to a customized sealing ring 5; the side wall of the customized sealing ring 5 is symmetrically provided with a second pipe connection groove 18; the connecting disk 8 is provided with through holes, and the through holes are arranged in a circumferential array; a screw rod 6 and a nut 19 are arranged between the through holes of the plurality of connecting disks 8; during operation, water flows through the internal channel composed of the control warehouse 1, the warehouse connecting pipe 2 and the connecting pipe 3. Among them, the control warehouse 1 and the warehouse connecting pipe 2 are in a fixed connection relationship. When the staff connects the warehouse connecting pipe 2 and the connecting pipe 3, they can first align the warehouse connecting pipe 2, the connecting pipe 3 and the customized sealing ring 5 so that the three are in the same direction. Then, a force can be applied to the connecting pipe 3 towards the warehouse connecting pipe 2 to make it move towards the warehouse connecting pipe 2. During the movement, the end of the customized sealing ring 5 will enter the first pipe connection groove 4 opened at the end of the connecting pipe 3, and the end of the connecting pipe 3 will enter the second pipe connection groove 18 opened at the end of the customized sealing ring 5. The customized sealing ring 5 fixedly connected to the end of the warehouse connecting pipe 2 enters the first pipe connection groove 4 at the end of the warehouse connecting pipe 2 along with the movement of the connecting pipe 3 during this process. The staff can keep the connecting pipe 3 moving towards the warehouse connecting pipe 2 until the warehouse connecting pipe 2, the connecting pipe 3 and the customized sealing ring 5 are connected. Finally, the nut 19 and the screw rod 6 are used to pass through the through holes of the connecting disk 8 to complete the fixing action; this step improves the sealing performance at the connection between the valve and the pipeline by setting the customized sealing ring 5 between the warehouse connecting pipe 2 and the connecting pipe 3, and makes the customized sealing ring 5 stressed by setting the spring 7 between the warehouse connecting pipe 2 and the customized sealing ring 5 to prevent the customized sealing ring 5 from loosening, which is beneficial to solving the leakage problem at the connection between the valve and the pipeline and extending the service life of the valve.

[0025] As Figures 1 to 3As shown, a connecting disk 8 is fixedly connected to the top of the control chamber 1; a limit box 11 is arranged on the top of the connecting disk 8; a limit block 14 is slidably connected inside the limit box 11; a control rod 12 is arranged on the top of the limit block 14, and the top of the control rod 12 is threadedly connected to a control dial 13; a control rod 12 is arranged on the bottom of the limit block 14, and a connecting block 15 is fixedly connected to the bottom of the control rod 12; a sealing block 16 is fixedly connected to the bottom of the connecting block 15; during operation, the staff can control the height position of the sealing block 16 through the control dial 13 and the control rod 12, and then control the opening and closing state of the internal channel of the control chamber 1. If the internal channel of the control chamber 1 is still in a closed state and needs to be opened, the staff can rotate the control dial 13 accordingly, and with the help of the threaded connection relationship between the control dial 13 and the control rod 12, and the limit block 1 located inside the limit box 11 4, the control rod 12 itself will move upward relative to the limit box 11. With the upward movement of the control rod 12, the connecting block 15 and the sealing block 16 fixed to the bottom of the control rod 12 will move upward accordingly. With the movement of the sealing block 16, the blocking effect of the sealing block 16 itself on the internal channel of the control chamber 1 will become invalid, and the channel inside the control chamber 1 will then be changed to an open state. If it is necessary to close the internal channel of the control chamber 1, the staff can reverse the control dial 13 until the internal channel of the control chamber 1 is closed. In this step, the sealing block 16 is set to block the channel inside the control chamber 1, and the position of the sealing block 16 is controlled by setting the control rod 12 and the control dial 13, thereby realizing flexible control of the opening and closing state of the valve, which is conducive to solving the problem that the liquid streamline at the valve is difficult to control, and improves the functionality and flexibility of the valve.

[0026] like Figure 1 and Figure 2 As shown, a fixing block 9 is fixedly connected to the end of the screw rod 6; a spring 7 is fixedly connected to the side wall of the fixing block 9; the ends of the multiple springs 7 away from the fixing block 9 are fixedly connected to the side wall of the connecting plate 8; during work, after the staff completes the connection action of the warehouse connecting pipe 2 and the connecting pipe 3, through the obstruction of the multiple fixing blocks 9, the multiple springs 7 can transmit their own internal force to the warehouse connecting pipe 2 and the connecting pipe 3, and make the two connecting plates 8 on the warehouse connecting pipe 2 and the connecting pipe 3 squeeze each other to achieve close contact between the two, and the passing personnel can also judge the connection status of the two connecting plates 8 by observing the length of the spring 7; this step provides prestress to the two connecting plates 8 by setting the spring 7 and the fixing block 9, which is conducive to solving the problem of loose connection between the valve and the pipeline, improving the tightness of the connection between the valve and the pipeline, and reducing the possibility of leakage.

[0027] like Figure 4As shown in the figure, an anti-leakage rubber ring 17 is provided inside the first pipe connection groove 4; an anti-leakage rubber ring 17 is fixedly connected inside the second pipe connection groove 18; during operation, after the staff connects the bin connecting pipe 2, the connecting pipe 3 and the customized sealing ring 5, multiple anti-leakage rubber rings 17 are in a compressed state inside the bin connecting pipe 2, the connecting pipe 3 and the customized sealing ring 5. After being compressed, the multiple anti-leakage rubber rings 17 are deformed, thereby filling the gaps between the bin connecting pipe 2, the connecting pipe 3 and the customized sealing ring 5; this step improves the sealing performance of the connection by setting multiple anti-leakage rubber rings 17, avoiding liquid leakage through the gaps between the bin connecting pipe 2, the connecting pipe 3 and the customized sealing ring 5, and further enhancing the anti-leakage ability of the valve.

[0028] As Figures 1 to 3 shown, a connecting plate 8 is provided on the top of the connecting plate 8 located at the top of the control bin 1, and the two connecting plates 8 are arranged in parallel; a convex block 10 is fixedly connected to the top of the connecting plate 8 located at the top; the top of the convex block 10 is fixedly connected to the bottom of the limit box 11; during operation, the staff can separate the two connecting plates 8 by removing the screw 6 and the nut 19 between the two connecting plates 8. After the two connecting plates 8 are separated, the staff can then take out the connecting block 15 and the sealing block 16 from the inside of the control bin 1. The convex block 10 plays a role in restricting the control rod 12; this step realizes the repairability and replaceability of the sealing block 16 by setting a connecting plate 8 on the top of the control bin 1, avoiding the problem that the sealing block 16 or other internal components cannot be repaired after long-term use, which is beneficial to the daily maintenance of the valve and beneficial to extending the service life of the valve.

[0029] As Figure 3 shown, the limit block 14 adopts an octagonal column structure, and the edges are smoothed; during operation, the limit block 14 is in a sliding connection relationship with the limit box 11. With the octagonal column structure and smoothing treatment of the limit block 14, the movement of the limit block 14 is subject to less resistance; this step reduces the friction between structures through the octagonal column structure and smoothing treatment of the limit block 14, which is beneficial to the stable movement of the limit block 14 inside the limit box 11 and enhances the stability of the valve.

[0030] As Figures 1 to 3 shown, the surface of the control turntable 13 is sprayed with an anti-slip coating; during operation, the staff can more accurately control the opening and closing state of the valve with the help of the control turntable 13 sprayed with the anti-slip coating; this step increases the friction on the surface of the control turntable 13 by spraying the anti-slip coating on the surface of the control turntable 13, which is beneficial to reducing slipping and precise control.

[0031] During operation, water flows through the internal passage formed by the control chamber 1, the chamber connecting pipe 2, and the connecting pipe 3. The control chamber 1 and the chamber connecting pipe 2 are fixedly connected. When the staff connects the chamber connecting pipe 2 and the connecting pipe 3, they can first align the chamber connecting pipe 2, the connecting pipe 3, and the customized sealing ring 5 so that the three are in the same direction. Subsequently, a force can be applied to the connecting pipe 3 towards the chamber connecting pipe 2 to make it move towards the chamber connecting pipe 2. During the movement, the end of the customized sealing ring 5 will enter the first pipe connection groove 4 opened at the end of the connecting pipe 3, and the end of the connecting pipe 3 will enter the second pipe connection groove 18 opened at the end of the customized sealing ring 5. The customized sealing ring 5 fixedly connected to the end of the chamber connecting pipe 2 will enter the first pipe connection groove 4 at the end of the chamber connecting pipe 2 along with the movement of the connecting pipe 3 during this process. The staff can keep the connecting pipe 3 moving towards the chamber connecting pipe 2 until the chamber connecting pipe 2, the connecting pipe 3, and the customized sealing ring 5 are completely connected. Finally, the nut 19 and the screw 6 are used to pass through the through-hole of the connecting plate 8 to complete the fixing action. The staff can control the height position of the sealing block 16 by controlling the turntable 13 and the control rod 12, thereby controlling the opening and closing state of the internal passage of the control chamber 1. If the internal passage of the control chamber 1 is still in the closed state and needs to be opened, the staff can rotate the control turntable 13 accordingly. With the threaded connection relationship between the control turntable 13 and the control rod 12, and the restriction of the limiting block 14 located inside the limiting box 11, the control rod 12 itself will move upward relative to the limiting box 11. As the control rod 12 moves upward, the connecting block 15 and the sealing block 16 fixedly connected to the bottom of the control rod 12 will move upward accordingly. As the sealing block 16 moves, the blocking effect of the sealing block 16 on the internal passage of the control chamber 1 will fail, and the internal passage of the control chamber 1 will then change to the open state. If it is necessary to close the internal passage of the control chamber 1, the staff can reverse the control turntable 13 until the internal passage of the control chamber 1 is closed. After the staff completes the connection action of the chamber connecting pipe 2 and the connecting pipe 3, through the blocking of multiple fixing blocks 9, multiple springs 7 can conduct their internal forces to the chamber connecting pipe 2 and the connecting pipe 3, and make the two connecting plates 8 on the chamber connecting pipe 2 and the connecting pipe 3 squeeze each other to achieve their close contact. The staff can also judge the connection situation of the two connecting plates 8 by observing the length of the springs 7. After the staff connects the chamber connecting pipe 2, the connecting pipe 3, and the customized sealing ring 5, multiple anti-leakage rubber rings 17 are in a compressed state inside the chamber connecting pipe 2, the connecting pipe 3, and the customized sealing ring 5. After being compressed, the multiple anti-leakage rubber rings 17 deform, and then fill the gaps between the chamber connecting pipe 2, the connecting pipe 3, and the customized sealing ring 5. The staff can separate the two connecting plates 8 by disassembling the screw 6 and the nut 19 between the two connecting plates 8. After the two connecting plates 8 are separated, the staff can take out the connecting block 15 and the sealing block 16 from the inside of the control chamber 1. The convex block 10 plays a role in restricting the control rod 12. The limiting block 14 and the limiting box 11 are in a sliding connection relationship. With the octagonal column structure and smooth treatment of the limiting block 14, the movement of the limiting block 14 is subject to less resistance.The staff can more accurately control the opening and closing state of the valve by means of the control turntable 13 sprayed with an anti-slip coating.
