Description

Technical Field

[0001] This utility model belongs to the field of pneumatic regulating valve technology, specifically relating to a connection end of a pneumatic regulating valve. Background Technology

[0002] In industrial production processes, pneumatic control valves are widely used in various fluid transport systems to regulate parameters such as flow rate and pressure. Currently, the common method for installing and connecting existing pneumatic control valves to pipelines is to use multiple bolts to connect the connecting flanges on the pneumatic control valve to the connecting flanges on the pipeline. However, during installation, tools are needed to install each bolt onto the connecting flange one by one. This installation method makes the installation process of pneumatic control valves to pipelines cumbersome, consuming a lot of time and manpower. In some space-constrained environments, it is also difficult to operate, seriously affecting installation efficiency. Therefore, designing a connection end that facilitates the installation of pneumatic control valves to pipelines is of significant practical importance. Utility Model Content

[0003] To address the problems mentioned in the background section, this invention provides a connection end for a pneumatic control valve, thus resolving the cumbersome installation and connection steps of existing pneumatic control valves to pipelines.

[0004] A connection end for a pneumatic control valve includes a pneumatic control valve and a delivery pipeline.

[0005] The pneumatic regulating valve has a conveying hole on its side wall, and a groove is provided on the pneumatic regulating valve around the conveying hole. The groove is an annular groove.

[0006] The pneumatic regulating valve has an annular slot, an annular groove, and a notch, all of which are interconnected.

[0007] The pneumatic regulating valve is provided with a limiting mechanism, which includes a limiting slide cavity formed on the pneumatic regulating valve. The limiting slide cavity communicates with the annular groove and is a cylindrical cavity.

[0008] The limiting slide cavity is provided with a slide plate, the diameter of which is adapted to the inner diameter of the limiting slide cavity. A limiting head is fixed at one end of the slide plate, and a pull rod is fixed at the other end. A spring is sleeved on the pull rod inside the limiting slide cavity.

[0009] The conveying pipe is provided with an inner pipe head, and the outer periphery of the inner pipe head is provided with a boss that matches the groove. The thickness of the boss matches the depth of the groove, and the width matches the width of the groove. The boss and the groove are sealed by a sealing ring.

[0010] The conveying pipe is provided with an annular plug that matches the annular slot. The annular plug is provided with a steel ball that matches the notch. The steel ball matches the annular groove. A limiting hole is opened on the steel ball. The diameter of the limiting hole matches the diameter of the limiting head, and the limiting head is engaged inside the limiting hole.

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

[0012] This invention utilizes a unique structural design—the mating of the annular slot and the annular plug, the engagement of the groove and the boss, and the synergistic action of the steel ball, the annular groove, and the limiting mechanism—to eliminate the need for complex connecting components such as bolts during the installation of the pneumatic regulating valve and the delivery pipeline. During installation, simply align the annular plug with the annular slot and insert it. Simultaneously, the steel ball enters the annular groove through the notch. Under the action of the spring, the limiting head automatically engages with the limiting hole, completing the connection. This significantly simplifies the installation process and improves installation efficiency.

[0013] Compared to traditional bolted connections, the connection end of this invention does not require tools to install each bolt individually during installation, reducing manpower and time consumption. It is especially suitable for installation environments with limited space, demonstrating significant practicality and innovation. Attached Figure Description

[0023] like Figure 1-5 As shown;

[0024] A connection end for a pneumatic regulating valve.

[0025] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "Currently, when installing and connecting existing pneumatic control valves to pipelines, the common method is to use multiple bolts to connect the connecting flange on the pneumatic control valve to the connecting flange on the pipeline. However, during installation, tools are needed to install each bolt onto the connecting flange one by one. This installation method makes the installation and connection steps between the pneumatic control valve and the pipeline quite cumbersome, not only consuming a lot of time and manpower, but also making operation difficult in some space-constrained environments, seriously affecting installation efficiency." Considering practical use, this problem is clearly a real and difficult-to-solve issue. Therefore, to solve this technical problem, a connection end for a pneumatic control valve is provided.

[0026] like Figure 1-5 As shown in the figure;

[0027] Based on the above, this includes pneumatic regulating valve 1 and delivery pipeline 2.

[0028] The pneumatic regulating valve 1 has a conveying hole 11 on its side wall, and a groove 12 is provided on the pneumatic regulating valve 1 around the conveying hole 11. The groove 12 is an annular groove.

[0029] The pneumatic regulating valve 1 has an annular slot 13, an annular groove 14 and a notch 15, and the annular slot 13, annular groove 14 and notch 15 are all interconnected.

[0030] A limiting mechanism 16 is provided on the pneumatic regulating valve 1. The limiting mechanism 16 includes a limiting slide cavity 161 opened on the pneumatic regulating valve 1. The limiting slide cavity 161 communicates with the annular groove 14. The limiting slide cavity 161 is a cylindrical cavity.

[0031] A sliding plate 162 is provided inside the limiting slide cavity 161. The diameter of the sliding plate 162 is adapted to the inner diameter of the limiting slide cavity 161. A limiting head 163 is fixed at one end of the sliding plate 162, and a pull rod 164 is fixed at the other end. A spring 165 is sleeved on the pull rod 164 inside the limiting slide cavity 161.

[0032] The conveying pipe 2 is provided with an inner pipe head 21. The outer periphery of the inner pipe head 21 is provided with a boss 22 that matches the groove 12. The thickness of the boss 22 matches the depth of the groove 12, and the width matches the width of the groove 12. The boss 22 and the groove 12 are sealed by a sealing ring.

[0033] The conveying pipe 2 is provided with an annular plug 23 that is compatible with the annular slot 13. The annular plug 23 is provided with a steel ball 24 that is compatible with the notch 15. The steel ball 24 is compatible with the annular groove 14. A limiting hole 25 is provided on the steel ball 24. The diameter of the limiting hole 25 is compatible with the diameter of the limiting head 163, and the limiting head 163 is engaged inside the limiting hole 25.

[0034] Installation process

[0035] First, align the annular plug 23 of the delivery pipe 2 with the annular slot 13 of the pneumatic regulating valve 1, while ensuring that the steel ball 24 is aligned with the notch 15.

[0036] Then, the annular plug 23 is slowly inserted into the annular slot 13. As the insertion process proceeds, the steel ball 24 enters the annular groove 14 through the notch 15. During this process, due to the movement of the steel ball 24, the limiting head 163 in the limiting mechanism 16 is squeezed, causing the limiting head 163 to move into the limiting slide cavity 161 and compress the spring 165.

[0037] When the steel ball 24 moves to the position corresponding to the limiting slide cavity 161, under the elastic force of the spring 165, the limiting head 163 pops out and gets into the limiting hole 25 on the steel ball 24. At this time, the boss 22 is also just embedded in the groove 12, and the sealing ring between the boss 22 and the groove 12 plays a sealing role, completing the quick installation of the pneumatic regulating valve 1 and the conveying pipe 2.

[0038] Disassembly process

[0039] When it is necessary to disassemble the pneumatic regulating valve 1 and the conveying pipe 2, pull the lever 164 to disengage the limit head 163 from the limit hole 25.

[0040] Then, the conveying pipe 2 is pushed in the reverse direction, causing the annular plug 23 to be pulled out of the annular slot 13, while the steel ball 24 is removed from the annular groove 14 through the notch 15, thus completing the disassembly process.

[0041] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
