[0002] The vacuum baffle valve is a vacuum valve used to open or cut off the air flow in a vacuum system. Its working principle is to achieve sealing by the up and down movement of the valve plate through the valve stem.
[0003] The transmission parts of the vacuum flapper valve are manual, hand-operated and pneumatic, which can be selected according to needs. The vacuum flapper valve has the advantages of simple structure, short opening and closing time, safety and reliability, durability, and automatic control. It is widely used in high-tech fields such as electronics, chemical industry, metallurgy, aviation, aerospace, materials, biomedicine, atomic energy, and space exploration.
[0004] The main materials used for vacuum baffle valves are: aluminum alloy, carbon steel or stainless steel; its sealing element is: bellows.
[0005] The bellows has good sealing and fluid control functions, so that the valve has smaller fluid resistance and shorter opening and closing time during the opening and closing process, making the bellows the most mainstream seal for the flapper valve. However, the manufacturing cost of the bellows is relatively high, which makes the cost of the flapper valve high.
[0006] Therefore, in order to reduce equipment costs while maintaining the original sealing and fluid control functions, our company improved and optimized the seals. Utility Model Content
[0007] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a Y-type vacuum baffle valve, which can reduce equipment costs while maintaining sufficient sealing and has a fluid control function.
[0008] To achieve the above object, the utility model provides the following technical solutions: a Y-type vacuum baffle valve, comprising a valve body, a valve cover and a sealing member, wherein a first channel, a second channel and a sealing channel are arranged in the valve body, wherein the sealing channel is connected to the first channel and the second channel respectively, and the first channel is located above the second channel;
[0009] The sealing member includes a blocking column, a driving member and an elastic member, wherein the driving member is used to drive the blocking column to move along the sealing channel, and the elastic member is installed between the valve cover and the blocking column to apply thrust to the blocking column;
[0010] A first sealing component and a second sealing component are arranged in the valve body from top to bottom along the axial direction of the blocking column, a first sealing surface is arranged above the first channel in the sealing channel, and the first sealing component is arranged at the first sealing surface;
[0011] The sealing channel is located between the first channel and the second channel and is provided with a second sealing surface, and the second sealing component is provided on the second sealing surface or the blocking column.
[0012] In summary, the utility model has the following beneficial effects: an elastic member is arranged above the blocking column, and a downward thrust is applied by the elastic member. By utilizing the good elasticity of the elastic member, smaller fluid resistance and shorter opening and closing time can be achieved during the valve opening and closing process.
[0013] Through the design of the first sealing component and the second sealing component, the sealing between the first channel and the sealing channel, between the first channel and the second channel, and between the second channel and the sealing channel can be maintained during the up and down sliding process of the blocking column, thereby reducing costs while ensuring the reliability of the flapper valve function.

[0018] Reference Figure 1 and Figure 2As shown, in order to achieve the above purpose, the utility model provides the following technical solutions: a Y-type vacuum baffle valve, comprising a valve body 1, a valve cover 2 and a sealing member 3, wherein a first channel 11, a second channel 12 and a sealing channel 13 are arranged in the valve body 1, and the sealing channel 13 is connected to the first channel 11 and the second channel 12 respectively, and the first channel 11 is located above the second channel 12;
[0019] The sealing member 3 includes a blocking column 31, a driving member 32 and an elastic member 33. The driving member 32 is used to drive the blocking column 31 to move along the sealing channel 13. The elastic member 33 is installed between the valve cover 2 and the blocking column 31 to apply thrust to the blocking column 31.
[0020] A first sealing component 4 and a second sealing component 5 are arranged in the valve body 1 along the axial direction of the blocking column 31 from top to bottom. The sealing channel 13 is located above the first channel 11 and is provided with a first sealing surface 6. The first sealing component 4 is arranged at the first sealing surface 6.
[0021] The sealing channel 13 is located between the first channel 11 and the second channel 12 and is provided with a second sealing surface 7 . The second sealing component 5 is provided on the second sealing surface 7 or the blocking column 31 .
[0022] The design of the utility model is that an elastic member 33 is arranged above the blocking column 31. The elastic member 33 applies a downward thrust. By utilizing the good elasticity of the elastic member 33, the valve can have a smaller fluid resistance and a shorter opening and closing time during the valve opening and closing process.
[0023] Through the design of the first sealing component 4 and the second sealing component 5, the sealing between the first channel 11 and the sealing channel 13, between the first channel 11 and the second channel 12, and between the second channel 12 and the sealing channel 13 can be maintained during the up and down sliding process of the blocking column 31, thereby reducing costs while ensuring the reliability of the flapper valve function.
[0024] The elastic member 33 includes a spring. The upper end of the blocking column 31 is provided with a mounting groove 311 . The mounting groove 311 is extended along the axial direction of the blocking column 31 . One end of the spring abuts against the valve cover 2 , and the other end abuts against the bottom of the mounting groove 311 .
[0025] The design of this structure can provide a downward thrust to the blocking column 31 through the spring, thereby maintaining the stability of the seal.
[0026] Preferably, the mounting groove 311 is arranged around the center of the blocking column 31, and the design of this position can exert a stable downward thrust on the blocking column 31 when the spring is installed.
[0027] A thread groove 312 is provided at the center of the upper end of the blocking column 31 . The driving member 32 includes a threaded rod 321 . The threaded rod 321 is screwed into the thread groove 312 .
[0028] The design of this structure can drive the blocking column 31 to move up and down through the threaded groove 312 by rotating the threaded rod 321, thereby playing a role in controlling the blocking.

[0030] The second sealing component 5 includes a second limiting groove 51 provided at the bottom of the blocking column 31 and a second sealing ring 52 installed in the second limiting groove 51 .
[0031] like Figure 2 As shown, the design of the first sealing component 4 and the second sealing component 5 can separate the medium during the movement of the blocking column 31.
[0032] The diameter length of the blocking column 31 is greater than the diameter length of the second channel 12. The design of this structure, such as Figure 2 As shown, when the blocking column 31 abuts against the second sealing surface 7 , it can block the first channel 11 and the second channel 12 at the same time.
[0033] A smooth abutment surface 8 is provided on the outer side of the blocking column 31 for sealingly abutting against the inner cavity of the valve body 1 .
[0034] The blocking column 31 is used to replace the existing corrugated tube. Since the outer wall thereof is in a smooth structure, the process cost can be greatly reduced, thus effectively controlling the cost.
[0035] Furthermore, since the surface of the blocking column 31 is flat, it is not easy for stains to accumulate and is convenient to rinse.
[0036] The first channel 11 and the second channel 12 are respectively disposed on two sides of the valve body 1 and arranged in a Y-shaped structure.
[0037] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
