[0002] A multi-channel connector for gas pipelines refers to a device or component that can simultaneously connect multiple channels in a gas pipeline system.

[0003] One type of multi-channel connector is a three-way valve. As a common multi-channel connector, the three-way valve plays an important role in the gas pipeline system. It allows gas to flow or be distributed between three different channels. It has the advantages of compact structure, easy installation, and good sealing. The outside of the three-way valve has three threaded connections and two valve stems. The three threaded connections have two external thread connections and one internal thread connection, which are used to connect gas pipelines and other related components respectively.

[0024] The embodiment of the present application provides a multi-channel connector for a gas pipeline, which effectively solves the technical problem that when the gas pipeline system is often affected by vibration and temperature changes, the threaded connections are prone to loosening, resulting in an increased risk of leakage.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The technical solution in the embodiment of the present application effectively solves the technical problem that the gas pipeline system is often affected by vibration and temperature changes, and the threaded connections are prone to loosening, resulting in an increased risk of leakage. The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a multi-channel connector for a gas pipeline, which includes a valve body 1, the outside of the valve body 1 is rotatably connected to two valve stems 2, and the outside of the valve body 1 is provided with four limit mechanisms, each of which includes a mounting plate 3, a mounting hole 4, a screw 5, a connecting plate 6 and a limit plate 7, the mounting plate 3 is fixedly mounted on the outside of the valve body 1, the mounting hole 4 is opened on the outside of the mounting plate 3, the screw 5 is rotatably connected to the inside of the mounting hole 4, the connecting plate 6 is threadedly connected to the outside of the screw 5, and the limit plate 7 is arranged on the side of the connecting plate 6 away from the screw 5, the outside of each valve stem 2 is slidably connected to a fixing plate 8, and the fixing plate 8 is threadedly connected to the outside of the screw 5. By providing the limit plate 7, With the help of the fixing plate 8, when the threaded connection of the valve body 1 is connected to the connecting piece, the screw 5 is rotated to drive the fixing plate 8 and the connecting plate 6 to move downward. At this time, the connecting plate 6 drives the limit plate 7 to make the limit plate 7 contact with the connecting piece. At the same time, during this process, the fixing plate 8 moves downward until the fixing plate 8 is slid and connected to the outside of the valve stem 2. At this time, the valve stem 2 is fixed and cannot rotate. When the connecting piece is a nut, the limit plate 7 fits onto the outside of the nut. The existence of the limit plate 7 can provide an additional resistance to prevent the nut from loosening due to vibration or other external forces. When the connecting piece is a threaded connecting pipe, the two limit plates 7 clamp and fix the connecting pipe, reducing the problem of loosening of the threaded connection caused by factors such as vibration and temperature changes at the connection, improving the stability of the connection, and reducing the risk of leakage.

[0028] A rotating hole 9 is provided inside each mounting hole 4, and a connecting shaft 10 is rotatably connected to the inside of each rotating hole 9. The connecting shaft 10 consists of two cylinders. The connecting shaft 10 is fixedly mounted on the outside of the screw rod 5, which is a structure for mounting the screw rod 5 in the mounting hole 4. A handle 11 is provided on the upper surface of each mounting plate 3. The handle 11 consists of two cylinders and a number of rectangular plates. The handle 11 facilitates the user to rotate the screw rod 5. The handle 11 rotates through the mounting plate 3 to one end inside the mounting hole 4 and is fixedly mounted on the outside of the screw rod 5.

[0029] The outside of each connecting plate 6 is fixedly installed with a screw rod 2 12, and the limit plate 7 is slidably connected to the outside of the screw rod 2 12. The outside of each screw rod 2 12 is threadedly connected with a turntable 13. The outside of each turntable 13 is fixedly installed with several rotating plates 14, and the turntable 13 is threadedly connected to the outside of the screw rod 2 12. By setting the limit plate 7 and cooperating with the screw rod 2 12, the turntable 13 located on the outside of the screw rod 2 12 is rotated. At this time, the limit plate 7 moves with the turntable 13 until the position of the limit plate 7 meets the working requirements, which is convenient for adjusting the position of the limit plate 7 according to actual conditions and improving the flexibility of using the limit plate 7.

[0030] The outside of each limiting plate 7 is provided with a long plate 15, and the outside of each long plate 15 is slidably connected to two short plates 16. The short plate 16 is composed of a T-shaped plate and a rectangular plate. The short plate 16 is located between the two rotating plates 14, and the turntable 13 can be fixed to ensure the stability of the limiting plate 7. The outside of each limiting plate 7 is provided with a groove 17, and the inside of each groove 17 is fixedly installed with a fixed shaft 18. The long plate 15 is slidably connected to the outside of the fixed shaft 18, which is convenient for moving the long plate 15 so that the short plate 16 can enter between the corresponding two rotating plates 14. The outside of each long plate 15 is provided with a slide groove 19, and the inside of each slide groove 19 is fixedly connected to a spring 20. The two ends of the spring 20 are respectively fixedly connected to the outside of the two short plates 16, and the short plate 16 is slidably connected to the inside of the slide groove 19 to provide support for the short plate 16.

[0031] Working principle:

[0032] In the first step, when the connecting piece is a nut, after the threaded connection of the valve body 1 is connected to the connecting piece, the handle 11 is turned to drive the screw 1 5 to rotate. At this time, the fixed plate 8 and the connecting plate 6 move downward. At this time, the connecting plate 6 drives the limit plate 7 to make the limit plate 7 contact the connecting piece. During this process, the fixed plate 8 moves downward until the fixed plate 8 is slidably connected to the outside of the valve stem 2. At this time, the valve stem 2 is fixed and cannot rotate, reducing the probability of the valve stem 2 being rotated by accident;

[0033] In the second step, if the position of the limit plate 7 cannot fit the outside of the nut, the limit plate 7 will be blocked by the nut and cannot move downward. At this time, the short plate 16 is pushed to make the short plate 16 away from between the two rotating plates 14. At this time, according to the width of the nut, the turntable 13 located outside the screw rod 2 is rotated. At this time, the limit plate 7 can be pushed to move the limit plate 7 to a suitable position. At this time, the turntable 13 is rotated so that the two turntables 13 clamp and fix the limit plate 7. At this time, the short plate 16 is released. Under the action of the spring 20, the short plate 16 enters between the two rotating plates 14. At this time, the turntable 13 is fixed. At this time, the screw rod 1 is continued to be rotated to make the limit plate 7 fit the outside of the nut. The existence of the limit plate 7 can provide an additional resistance to prevent the nut from loosening due to vibration or other external forces. When the connecting piece is a threaded connecting pipe, the two limit plates 7 are located at both ends of the connecting pipe to clamp and fix the connecting pipe, reducing the probability of the connecting pipe loosening.

[0034] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
