Structure, principle and application of mechanical seal handle

I. Preface

In industrial production, the safety of mechanical equipment is very important, and mechanical seal handle, as a common equipment component, plays an important role in ensuring the safety of mechanical equipment. This paper will introduce its structure, working principle and application scenarios.

Second, the structure and characteristics

Mechanical seal handle is generally composed of handle, connecting rod, pin shaft, etc. Through reasonable structural design, it has good pressure resistance and stability, and can withstand greater external force to ensure that it can work normally in various harsh environments.

1. Handle: usually made of stainless steel, with strong corrosion resistance;

2. Connecting rod: it is used to connect the handle and the pin shaft, and it is also one of the key links in the whole device;

3. Pin: used to fix the position of the connecting rod and transmit power to other mechanisms.

Third, the working principle

When it is necessary to open or close some containers (such as reaction kettle, pressure tank, etc.), the operator can control the door body or cover plate by pulling the mechanical seal handle. The specific process is as follows:

1. The operator holds the handle by hand and pulls it upward to drive the internal connecting rod to rise;

2. The cam device on the connecting rod rotates and pushes the locking mechanism to loosen;

3. At this time, the door body/cover can be opened smoothly;

4. After closing, repeat the above steps to complete the locking action.

Fourth, the application scenario

Mechanical sealing handles are widely used in various containers that need to be opened and closed frequently in chemical industry, pharmaceutical industry, food processing and other industries. For example:

1. Reaction kettle: it is used in the processes of material mixing and heating treatment in the chemical reaction process, and requires good sealing performance to prevent the leakage of harmful gases;

2. Autoclave: it is mainly used for disinfection and sterilization of medical instruments, and it is necessary to ensure that the internal pressure is stable and does not leak;

3. Vacuum drying oven: it is suitable for occasions with high working environment requirements such as laboratory sample testing and material analysis.

V. Conclusion

To sum up, the mechanical seal handle is a simple and practical but vital device, which plays an indispensable role in many industries. With the continuous progress and development of technology, there may be more new models of products in the future to meet the challenges brought by changes in market demand!
