Description
Technical Field
[0001] The utility model relates to the technical field of vacuum pumping equipment, in particular to a novel temperature-adjustable vacuum pumping device. Background Art
[0002] Traditional vacuum pumping devices simply discharge gas to the outside to create an extremely low-pressure environment. As the application scope of vacuum technology becomes wider and wider, the requirements for vacuum degree are getting higher and higher. It is difficult to meet the flexible requirements of vacuum degree in different application scenarios. In order to better meet the needs of different scenarios, adjustable vacuum pumping devices came into being.
[0003] Existing technologies include: rotary vacuum pumps, which use rotating mechanical devices such as vanes, screws or centrifugal mechanisms to create vacuum, turbomolecular pumps, which extract gas molecules through a high-speed rotating turbine to produce high vacuum levels, diffusion pumps, which transfer gas molecules from high-pressure areas to low-pressure areas to create vacuum, ion pumps, which use ionized gas molecules to produce high vacuum and ultra-high vacuum, grid ionization vacuum regulators, which control the flow of gas molecules by changing the electric field to achieve vacuum level adjustment, progressive vacuum devices, which adjust the vacuum level by gradually closing valves or changing the operating speed of the pump, and molecular flow controllers, which control the vacuum level by adjusting the gas flow.
[0004] However, in order to ensure good sealing and firm connection during installation, existing equipment uses a large number of connection structures. The large number of connection structures used will prolong the installation time of the valve body, increase the risk of failure, maintenance cost and workload. Failure of any connection point will lead to failure of the entire system. Therefore, a new type of temperature-controlled adjustable vacuum device is proposed to solve the above problems. Utility Model Content
[0005] In order to remedy the above deficiencies, the utility model provides a novel temperature-adjustable vacuum pumping device, which aims to improve the problems in the prior art of using a large number of connection structures when installing the valve body, which leads to cumbersome equipment installation and disassembly and increases the risk of failure and maintenance costs.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a novel temperature-lowering adjustable vacuum pumping device, comprising a vacuum tank, a valve body being slidably connected to the top of the vacuum tank, pulling blocks being threadedly connected to the upper and lower sides of the outer periphery of the valve body, the two pulling blocks are rotatably connected to the far ends of the two pulling blocks, the left and right sides of the two fixed blocks are slidably connected to the limiting blocks, a plurality of the limiting blocks are respectively fixedly connected to the upper and lower ends of the valve body, the front and rear sides of the interiors of the two fixed blocks are slidably connected to the clamping blocks, the far sides of the plurality of clamping blocks are fixedly connected to the pulling rods, one side of the plurality of clamping blocks are fixedly connected to two telescopic rods, the other ends of the plurality of telescopic rods are respectively fixedly connected to the insides of the two fixed blocks, the outer peripheries of the plurality of telescopic rods are sleeved with springs, and the upper part of the valve body is slidably connected to a pipeline.
[0007] Furthermore, the upper and lower ends of the valve body are fixedly connected with protective layers, the interiors of the two protective layers are fixedly connected with sealing layers, the lower sides of the two sealing layers are fixedly connected with supporting layers, and the supporting layers are fixedly connected to the interiors of the protective layers.
[0008] Furthermore, a plurality of evenly distributed brackets are fixedly connected to the bottom of the vacuum tank.
[0009] Furthermore, the two pulling blocks are respectively located on the inner sides of the plurality of limit blocks and the valve body.
[0010] Furthermore, one end of the two pulling blocks is configured to be L-shaped.
[0011] Furthermore, the protective layer is made of fluororubber.
[0012] Furthermore, the sealing layer is made of polytetrafluoroethylene.
[0013] Furthermore, the supporting layer is made of glass fiber reinforced plastic.
[0014] The utility model has the following beneficial effects:
[0015] When the two clamping blocks on the lower side are respectively stuck in the two mounting grooves, the multiple telescopic rods and the multiple springs will rebound. At this time, the two clamping blocks on the lower side will firmly clamp the upper end of the vacuum tank. Then, the pulling block on the lower side is rotated. When the upper end of the vacuum tank contacts the surface of the protective layer on the lower side, it continues to rotate until the pulling block on the lower side is locked. In this way, the installation of one end of the valve body can be completed. When disassembling, the two pull rods in symmetrical positions need to be pulled. At this time, the two pull rods will pull the two clamping blocks to be embedded in the fixed blocks at the corresponding positions. Multiple telescopic rods and the multiple springs will be squeezed and contracted. Then, the valve body at one end of the corresponding position can be removed by performing the reverse operation according to the installation steps. The same operation can be performed on the upper end of the valve body to realize the function of quick installation and disassembly of the valve body.
[0016] 2. In the utility model, in order to achieve the highest sealing effect, a sealing layer and a supporting layer are stacked inside the sealing gasket to ensure the structural stability of the sealing gasket, and a protective layer is wrapped outside the sealing layer and the supporting layer to increase the service life of the sealing gasket. The protective layer is used to resist erosion and damage from the external environment, the sealing layer is used to ensure that the sealing gasket achieves a good sealing effect during operation and prevents liquid or gas leakage, and the supporting layer is used to prevent the sealing layer from being deformed or damaged due to force. The cooperation of the multi-layer structure achieves the function of good sealing of the valve body installation. BRIEF DESCRIPTION OF THE DRAWINGS

The multiple pull rods 5 are used to pull the multiple blocks 7 to slide respectively. One side of the multiple blocks 7 is fixedly connected with two telescopic rods 6. The multiple telescopic rods 6 are used to fix the multiple blocks 7 respectively to prevent the multiple blocks 7 from moving uncoordinatedly. The other ends of the multiple telescopic rods 6 are fixedly connected to the inside of the two fixed blocks 4 respectively. The outer peripheries of the multiple telescopic rods 6 are sleeved with springs 8. The multiple springs 8 are used to push the multiple blocks 7 back to their original positions respectively.

Repeating this process can achieve the complete installation of the valve body 2. When disassembling, it is necessary to pull the two pulling rods 5 in the symmetrical positions. At this time, the two pulling rods 5 will pull the two card blocks 7 to embed into the fixed blocks 4 at the corresponding positions. Multiple telescopic rods 6 and multiple springs 8 will be squeezed and contracted. Then, the valve body 2 at one end of the corresponding position can be removed according to the reverse operation of the installation steps. Repeating the operation at the other end can achieve the complete disassembly of the valve body 2. A two-layer structure is stacked, and the outer layer is nested in the third layer to achieve the stability and safety of the seal.
