Description

Technical Field

[0001] This utility model relates to the field of gate valve chuck connection technology, specifically a gate valve device with anti-disengagement chuck quick connection. Background Technology

[0002] In industrial piping systems, gate valves are crucial control components used to regulate or cut off fluid flow. With continuous technological advancements, chuck quick-connect gate valves have emerged to enable rapid assembly of gate valves with pipelines. The chuck connection method greatly simplifies the installation and disassembly process. Traditional gate valves often require cumbersome threaded or flanged connections, which are time-consuming and labor-intensive. In contrast, chuck quick-connect gate valves achieve a secure connection to the pipeline simply through the quick docking of the chuck structure, significantly improving work efficiency.

[0003] In practical applications, the connection and fastening of the two chucks is mainly achieved by clamps. However, when tightening the clamps, the clamps are mainly tightened by tightening the nuts, relying on the friction between the nuts and the chucks. Since the slots on the chucks are open, the screw may come out of the slot when tightening the nuts, which has certain limitations.

[0004] To address this, we designed an anti-detachment chuck-type quick-connect stop valve based on actual assembly requirements. By designing a settling groove on the clamp plate corresponding to the nut, the nut sinks into the settling groove when tightened, effectively limiting the nut's position and preventing the screw from coming out of the groove. The design is simple, novel, and highly practical. Utility Model Content

[0005] The purpose of this invention is to provide an anti-detachment chuck quick-connect shut-off valve device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick-connect shut-off valve device with anti-detachment chuck includes a valve body and a pipe body sealed to the valve body via a chuck assembly. The chuck assembly includes a valve body chuck and a pipe chuck respectively disposed at the ends of the valve body and the pipe body. A sealing rubber ring is provided between the valve body chuck and the pipe chuck. A clamp is fitted on the outside of the valve body chuck and the pipe chuck. A clamp plate is provided at both ends of the clamp. A screw is hinged to one side of the clamp plate, and a nut is threaded to the end of the screw. A groove corresponding to the screw is opened on the other side of the clamp plate, and the screw can be inserted into the groove. An anti-detachment component is provided on the groove to prevent the screw from detaching from the groove.

[0008] As a further preferred embodiment of this utility model: the anti-detachment component includes a settling hole opened at the upper end of the slot, and the lower end of the nut can fall into the settling hole.

[0009] As a further preferred embodiment of this utility model: the lower end of the nut is provided with a locking platform corresponding to the settling hole.

[0010] As a further preferred embodiment of this utility model: corresponding positioning grooves are provided on the side walls of the valve body chuck and the pipe chuck, and corresponding positioning protrusions are provided on both sides of the sealing rubber ring, which can be locked in the positioning grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This chuck quick-connect stop valve device is scientifically and rationally designed. By opening a settlement hole in the clamp plate and setting a corresponding clamping platform at the bottom of the nut, the screw can be inserted into the groove before tightening the nut, and the clamping platform at the bottom of the nut can be pressed into the settlement hole. Then, tightening the nut will passively insert the screw into the nut, thereby driving the clamp to close. The settlement hole limits the clamping platform, preventing the screw from coming out of the groove during tightening. This improves the efficiency of connecting the stop valve to the pipeline and ensures the stability of the screw after assembly. The structure is simple, novel, and highly practical.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0019] Please see Figure 1-4 This embodiment provides an anti-detachment chuck quick-connect shut-off valve device, including a valve body 1 and a pipe body 2 sealed and connected to the valve body 1 via a chuck assembly. Specifically, the chuck assembly includes a valve body chuck 3 and a pipe chuck 4 respectively disposed at the ends of the valve body 1 and the pipe body 2. A sealing rubber ring 6 is provided between the valve body chuck 3 and the pipe chuck 4. A clamp 8 is sleeved on the outside of the valve body chuck 3 and the pipe chuck 4. Clamping plates 14 are provided at both ends of the clamp 8. A screw 9 is hinged to one clamping plate 14, and a nut 11 is threaded to the end of the screw 9. A groove 10 corresponding to the screw 9 is opened on the other clamping plate 14, allowing the screw 9 to be inserted into the groove 10. An anti-detachment component is provided on the groove 10 to prevent the screw 9 from detaching from the groove 10. Specifically, as shown... Figure 4 As shown, the anti-disengagement component includes a settling hole 13 formed at the upper end of the slot 10, allowing the lower end of the nut 11 to fall into the settling hole 13. To ensure the lower end of the nut 11 is stably secured in the settling hole 13, as shown... Figure 2 As shown, a retaining plate 12 corresponding to the settling hole 13 is provided at the lower end of the nut 11.

[0020] Meanwhile, to ensure quick installation of the sealing rubber ring 6 and accurate alignment of the sealing rubber ring 6 with the chucks on both sides, such as... Figure 1 as well as Figure 3 As shown, corresponding positioning grooves 5 are provided on the side walls of the valve body chuck 3 and the pipeline chuck 4, and corresponding positioning protrusions 7 are provided on both sides of the sealing rubber ring 6. The positioning protrusions 7 can be locked in the positioning grooves 5.

[0021] It should be noted that the shut-off valve described in this application is only one conventional valve body type for valve body 1. Those skilled in the art can also choose other conventional valve body types to achieve connection with pipelines according to their needs. This application will not elaborate on the limitations.

[0022] Meanwhile, it should be noted that the clamp 8, clamp plate 14, clamp groove 10, screw 9 and nut 11 described in this application can all be obtained directly through customization and are conventional and common structures familiar to those skilled in the art. In actual processing, it is only necessary to open the sink hole 13 on the upper side of the clamp groove 10 on the clamp plate 14 and mill the corresponding clamping platform 12 at the bottom of the nut 11. This should be a conventional processing method familiar to those skilled in the art, and will not be described in detail.

[0023] In actual assembly, the assembly method of this device differs from that of traditional gate valves and pipelines. Specifically, first, align the valve body chuck 3 with the pipeline chuck 4, and position the sealing rubber ring 6 between the two chucks. Then, place the clamp 8 on the outside of the two chucks. Next, rotate the screw 9 so that it is positioned in the groove 10, and press down the nut 11 so that the retaining plate 12 at the bottom of the nut 11 engages with the settling hole 13. Then, rotate the nut 11, and the screw 9 will move into the nut 11, causing the clamp 8 to close. Finally, tighten the nut 11.

[0024] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.
