[0031] See also Figure 1-4 As shown, the utility model provides a technical solution of a multi-way valve with excellent connection sealing performance: a multi-way valve with excellent connection sealing performance, comprising a valve body 1, a plurality of connectors 2 are fixedly installed on the outside of the valve body 1, one end of the connector 2 is provided with an external thread 3 for connecting with an oil pipe, a leak-proof component 4 is installed on the inside of the connector 2, and a linkage component 5 for controlling the leak-proof component 4 is also installed on the inside of the connector 2. The leak-proof component 4 includes a mounting ring 401, a flow channel 403 and a connecting rod 404. The mounting ring 401 is installed in a mounting groove on the inner wall of the connector 2, and a sealing ball 402 is movably installed in the interior of the mounting ring 401 by opening a spherical groove. The flow channel 403 is centrally penetrated and opened in the sealing ball 402. One end of the connecting rod 404 is rotatably connected to a side wall of the sealing ball 402 passing through the transverse groove on the mounting ring 401, and the other end of the connecting rod 404 is connected to the linkage component 5. When no pipeline is connected to the connector 2, the connecting rod 404 is in an inclined state. When the external oil pipe is connected to the connector 2 on the multi-way valve, the linkage assembly 5 drives the connecting rod 404 to move toward the inside of the connector 2, thereby pushing the sealing ball 402 to rotate, so that the two ends of the flow channel 403 inside the sealing ball 402 are aligned with the holes at the two ends of the mounting ring 401, and the hydraulic oil can flow normally in the connector 2. When the external oil pipe is separated from the connector 2 on the multi-way valve, the linkage assembly 5 drives the connecting rod 404 to move toward the outside of the connector 2, thereby pulling the sealing ball 402 to rotate in the opposite direction until the two ends of the flow channel 403 are completely enclosed in the mounting ring 401, and the connector 2 is also enclosed at this time, and the hydraulic oil cannot flow normally. Through the anti-leakage assembly 4, the effect of sealing the connector 2 by using the sealing ball 402 is achieved when the external oil pipe is separated from the multi-way valve, so as to prevent the hydraulic oil in the multi-way valve from leaking outward after the external oil pipe is removed, thereby saving hydraulic oil, and effectively protecting the interior of the multi-way valve when the external oil pipe is separated from the multi-way valve, preventing external impurities from entering the valve body 1, and improving the service life of the multi-way valve.

[0032] The linkage assembly 5 includes a control block 501, a drainage hole 504 and a spring 505. The control block 501 is slidably connected to the inside of the connector 2, and the end of the connecting rod 404 away from the sealing ball 402 is rotatably connected to the end of the control block 501. A slide groove 502 is provided on the inner wall of the connector 2, and a slider 503 is integrally formed on the outer wall of the control block 501, and the slider 503 is slidably connected to the slide groove 502. The drainage hole 504 is provided inside the control block 501. The spring 505 is movably installed between the control block 501 and the mounting ring 401. When the external oil pipe is docked with the connector 2 on the multi-way valve, the control block 501 receives the thrust from the top of the external oil pipe and overcomes the elastic force of the spring 505 to slide along the slide groove 502 toward the mounting ring 401, and generates thrust on the connecting rod 404 to drive the sealing ball 402 to rotate, so that the hydraulic oil can flow in the connector 2. When the external oil pipe is separated from the connector 2 on the multi-way valve, as the external oil pipe is pulled out, the control block 501 is reset under the action of the spring 505 and slides in a direction away from the mounting ring 401, thereby pulling the sealing ball 402 to rotate and reset through the connecting rod 404. Through the linkage component 5, the connector 2 is opened and closed synchronously when the external oil pipe is inserted and pulled out, which has a simple structure, convenient operation, and does not require separate control, further improving the protection effect of the multi-way valve and ensuring the connection efficiency between the multi-way valve and the external pipeline.

[0033] The inner diameter of the flow channel 403 matches the apertures at both ends of the mounting ring 401 , and the apertures at both ends of the mounting ring 401 may be larger than the inner diameter of the flow channel 403 .

[0034] A sealing ring 6 is installed at the end of the connector 2 by providing a mounting groove, and the sealing ring 6 is used to ensure the sealing performance of the connection between the multi-way valve and the external pipeline.

[0035] The distance from the inner side of the slide groove 502 to the end of the connector 2 is greater than the length of the control block 501 . After the external pipeline is installed, the control block 501 can be completely retracted into the connector 2 .

[0036] The spring 505 is made of stainless steel material. The stainless steel spring 505 has the characteristics of corrosion resistance, long service life and good stability.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
