Description

Technical Field

[0001] This utility model relates to the field of start-up control technology, and in particular to a manual integrated shuttle valve. Background Technology

[0002] Currently, multi-source gas supply equipment, especially dual-source gas supply equipment, has been gradually accepted by the market. It greatly expands the user's choice of gas source and is suitable for scenarios such as industrial automation and construction machinery that require redundant control of multiple gas sources, thereby improving the safety of gas supply equipment.

[0003] Traditional shuttle valves are mainly used in pneumatic systems to achieve dual air source switching. However, traditional shuttle valves usually only support dual air source switching. If independent control or common air source switching is required in multiple air sources, multiple independent shuttle valves need to be connected in parallel and equipped with additional control valves. This decentralized layout leads to complex piping and low space utilization. Moreover, the common air source and independent air source cannot be controlled in an integrated manner: if the existing shuttle valve system needs to support independent air source input and centralized control of common air source at the same time, additional switching valve groups and control logic need to be configured, which is cumbersome and costly. Utility Model Content

[0004] This invention provides a manually operated integrated shuttle valve, thereby effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a manual integrated shuttle valve, comprising:

[0006] A manual control valve, which is a two-position three-way valve, includes an air inlet end and an air outlet end, and the air inlet end is connected to a common air source input.

[0007] A plurality of integrated shuttle valves are configured as one unit, and each integrated shuttle valve includes an independent air inlet, a common air passage and an independent air outlet, wherein the independent air inlet of the integrated shuttle valve is connected in parallel with the common air passage;

[0008] The air outlet is connected to the common air path, so that the independent air source of each integrated shuttle valve's independent air inlet competes with the common air source.

[0009] Furthermore, the manual control valve includes a first state and a second state. In the first state, the air inlet end is disconnected from the air outlet end, and each integrated shuttle valve has an independent air source outputting from the independent air inlet to the independent air outlet.

[0010] In the second state, the air inlet end is connected to the air outlet end, and the independent air source of each integrated shuttle valve competes with the common air source.

[0011] Furthermore, it also includes a pneumatic control indicator light, which is connected to the air outlet of the manual control valve. When the common air source is output to the air outlet, the pneumatic control indicator light is triggered and illuminated.

[0012] Furthermore, the integrated shuttle valve is provided with a competing chamber, in which a ball is provided. Sealing rings are provided at the upper and lower ends of the competing chamber. The competing chamber is connected to the independent air outlet. The upper and lower ends of the competing chamber are connected to the common air path and the independent air inlet, respectively. The common air source in the common air path and the independent air source in the independent air inlet compete with each other. The air source with higher air pressure pushes the ball to the other end. The ball and the sealing ring form a one-way valve structure.

[0013] Furthermore, the manual control valve and several integrated shuttle valves are integrated into one unit, with the manual control valve located at one end and the several integrated shuttle valves located at the other end. The independent air inlet and independent air outlet are located at the end away from the manual control valve.

[0014] Furthermore, the independent air inlets of several integrated shuttle valves are located on the same side, and the independent air outlets of several integrated shuttle valves are located on the other side.

[0015] Furthermore, the valve body, which integrates the manual control valve and several integrated shuttle valves into one unit, is cubic.

[0016] Furthermore, it also includes a common exhaust port, which is connected to the common air passage and is used for the discharge of common air source.

[0017] The beneficial effects of this invention are as follows: By integrating multiple shuttle valves into a single structure, coupled with a manually controlled two-position three-way valve, unified switching and control of multiple independent air sources and a common air source are achieved. Compared to the traditional distributed arrangement requiring multiple shuttle valves and switching valve groups in parallel, this solution significantly simplifies pipeline design, saves installation space, and reduces system complexity. Simultaneously, by manually controlling the common air source switch, automatic competition between the common and independent air sources is achieved, ensuring that the system can still operate from independent air sources when the common air source is disconnected, thus improving system redundancy and reliability. This structure is easy to operate, low in cost, and particularly suitable for industrial scenarios with limited space or high reliability requirements. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] like Figures 1 to 5 As shown: A manually operated integrated shuttle valve, comprising:

[0026] Manual control valve 1 is a two-position three-way valve. Manual control valve 1 includes an air inlet end 11 and an air outlet end 12. The air inlet end 11 is connected to a common air source input.

[0027] Several integrated shuttle valves 2 are configured as one unit, and each integrated shuttle valve 2 includes an independent air inlet 21, a common air passage 22 and an independent air outlet 23. The independent air inlet 21 of the integrated shuttle valve 2 is connected in parallel with the common air passage 22.

[0028] The outlet end 12 is connected to the common air passage 22, so that the independent air source of each integrated shuttle valve 2's independent air inlet 21 competes with the common air source.

[0029] By integrating multiple shuttle valves into a single structure, along with a manually controlled 2-position 3-way valve, unified switching and control of multiple independent air sources and a common air source is achieved. Compared to the traditional distributed arrangement requiring multiple shuttle valves and switching valve groups in parallel, this solution significantly simplifies piping design, saves installation space, and reduces system complexity. Simultaneously, by manually controlling the common air source switch, automatic competition between the common and independent air sources is achieved, ensuring that the system can continue operating from independent air sources even when the common air source is disconnected, thus improving system redundancy and reliability. This structure is easy to operate and low in cost, making it particularly suitable for space-constrained or high-reliability industrial scenarios.

[0030] In this embodiment, the manual control valve 1 includes a first state and a second state. In the first state, the air inlet end 11 is disconnected from the air outlet end 12, and each integrated shuttle valve 2 has an independent air source that outputs from the independent air inlet 21 to the independent air outlet 23.

[0031] In the second state, the air inlet end 11 is connected to the air outlet end 12, and the independent air source of each integrated shuttle valve 2 competes with the common air source.

[0032] In the first state, the air inlet 11 and air outlet 12 of the manual control valve 1 are disconnected, and the common air source is shut off. At this time, each integrated shuttle valve 2 is supplied with air from its corresponding independent air source through its independent air inlet 21 to its independent air outlet 23, thereby realizing independent air supply control for each channel. In the second state, the air inlet 11 and air outlet 12 of the manual control valve 1 are connected, and the common air source is connected to the common air circuit 22. The independent air source of each integrated shuttle valve 2 and the common air source form a competition relationship in the common air circuit 22, thereby realizing unified centralized air supply control of the common air source.

[0033] By simply switching between two-position three-way valves, it is possible to flexibly switch between "independent gas supply" and "centralized gas supply" modes, which not only ensures the flexibility of the system, but also improves the convenience and reliability of operation.

[0034] It also includes a pneumatic control indicator light 13, which is connected to the air outlet 12 of the manual control valve 1. When the common air source is output to the air outlet 12, the pneumatic control indicator light 13 is triggered to light up.

[0035] The pneumatic control indicator light 13 is connected to the outlet end 12 of the manual control valve 1. When the manual control valve 1 is in the second state and the common gas source outputs to the outlet end 12, the pneumatic control indicator light 13 is triggered and illuminated upon receiving the gas source drive signal, thus providing a visual indication of the common gas source supply status. This design allows operators to intuitively determine whether the common gas source is in the open state, improving the system's safety and management convenience.

[0036] In this embodiment, the integrated shuttle valve 2 is provided with a competing chamber 24, and a ball bearing 241 is provided in the competing chamber 24. Sealing rings 242 are respectively provided at the upper and lower ends of the competing chamber 24. The competing chamber 24 is connected to the independent air outlet 23. The upper and lower ends of the competing chamber 24 are respectively connected to the common air passage 22 and the independent air inlet 21. The common air source in the common air passage 22 and the independent air source in the independent air inlet 21 compete with each other. The air source with higher air pressure pushes the ball bearing 241 to the other end. The ball bearing 241 and the sealing ring 242 form a one-way valve structure.

[0037] Each integrated shuttle valve 2 has a competing chamber 24 for automatic switching and isolation between air sources. The competing chamber 24 contains a ball bearing 241, with sealing rings 242 at its upper and lower ends. One side of the competing chamber 24 connects to an independent air outlet 23, while its upper and lower ends connect to a common air passage 22 and an independent air inlet 21, respectively. During operation, the common and independent air sources simultaneously act on the competing chamber 24, creating pressure competition. The air source with higher pressure pushes the ball bearing 241 towards the side with lower pressure. When the ball bearing 241 contacts the sealing ring 242, it forms a one-way valve structure, automatically closing the channel on the side with lower pressure, thus achieving the function of opening the priority channel and cutting off the secondary channel.

[0038] The manual control valve 1 and several integrated shuttle valves 2 are integrated into one unit. The manual control valve 1 is located at one end, and the several integrated shuttle valves 2 are located at the other end. The independent air inlet 21 and the independent air outlet 23 are located at the end away from the manual control valve 1.

[0039] The manual control valve 1 and several integrated shuttle valves 2 are integrated into a single structure. The manual control valve 1 is located at one end and is used to control the on / off state of the common air source. The integrated shuttle valves 2 are located at the other end and are used to switch between independent air sources and the common air source. The independent air inlet 21 and independent air outlet 23 of each integrated shuttle valve 2 are located at the end away from the manual control valve 1, making the air path layout clearer and facilitating centralized arrangement of interfaces and pipeline connections. The integrated design is compact and easy to install, which can significantly reduce the complexity of system integration and improve space utilization, making it suitable for industrial automation applications with high requirements for installation space and wiring.

[0040] As a preferred embodiment of the above, the independent air inlets 21 of the plurality of integrated shuttle valves 2 are located on the same side, and the independent air outlets 23 of the plurality of integrated shuttle valves 2 are located on the other side.

[0041] The independent air inlets 21 of several integrated shuttle valves 2 are located on the same side, and the independent air outlets 23 are located on the other side. This symmetrical distribution is conducive to the unified layout of pipelines, simplifies installation and maintenance, improves interface identification, and reduces the risk of incorrect connection.

[0042] The manual control valve 1 and several integrated shuttle valves 2 are integrated into a single cubic valve body. This cubic structure facilitates modular installation and standardized production, while also offering greater adaptability in spatial layout, making it suitable for integration into compact equipment.

[0043] In this embodiment, a common exhaust port 3 is also included. The common exhaust port 3 is connected to the common gas passage 22 and is used to discharge the common gas source. The common exhaust port 3 is connected to the common gas passage 22 to release the pressure of the common gas source or discharge residual gas when needed, thereby improving the safety and ease of maintenance of the system.

[0044] like Figure 5 As shown, the principle of the manually operated integrated shuttle valve in this embodiment is as follows:

[0045] The two-position three-way manual control valve has an inlet P connected to a common air source C, and an outlet A connected to the common end of the four shuttle valves 2-1 to 2-4 in the lower part through an internal flow channel; the upper and lower parts are connected by threads, and there is a sealing ring in the middle to prevent gas leakage.

[0046] Each shuttle valve in the lower part has an independent air inlet IN1-IN4 and an air outlet OUT1-OUT4. It adopts a ball-type one-way valve structure. There is a bidirectional competition channel between the independent air inlet IN1-IN4 of each shuttle valve and the common air source input end, which allows the air pressure to automatically select the high-pressure side output. That is, when the air pressure at the common end is higher than the independent air inlet, the ball is lifted up, and the common air source is given priority to output to the independent air outlet.

[0047] 1) Independent mode: Manual control valve 1 is closed, and the air source enters the shuttle valve through each independent air inlet IN1-IN4 and is output to the corresponding air outlet OUT1-OUT4;

[0048] 2) Common mode: When manual control valve 1 is opened, the common air source C enters the air inlet P of manual control valve 1 from the auxiliary air passage of the shuttle valve body, flows from the handle valve core assembly to the common air inlet C1-C4 of the four shuttle valves, competes with the independent air source and outputs, and at the same time the air control indicator D lights up.

[0049] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
