In today's society, with the continuous development of science and technology and the improvement of people's living standards, people's requirements for environmental protection and stability are getting higher and higher. In construction, transportation, water and other fields, plugging is a common design element used to stop the leakage of material, water flow or pressure. The design of sealing with pressure, as an important sealing method, has been widely used in various fields.

The design of sealing with pressure refers to the technical means to achieve effective sealing of containers, pipelines and equipment through reasonable structural design and material selection under certain pressure conditions. It can ensure the stable operation of the system, but also can improve work efficiency, save resources, reduce costs. In engineering practice, the design of sealing with pressure is a very important and indispensable work, and its application field involves many industries and fields.

In the field of construction, the design with pressure closure is often used in water engineering. For example, in the basement of the building, water tank, pool and other places, through the appropriate materials and construction technology, to achieve water blocking, to ensure the structural stability and service life of the building. In addition, in the fire stability design of high-rise buildings, the design with pressure sealing also plays a vital role, which can effectively prevent the spread of smoke and fire and ensure the stability of personnel.

In the field of transportation, the design of pressure closure is widely used in pipeline systems and oil and gas transportation. Oil and gas pipeline in the process of transportation, if the leakage will bring serious stability risks and environmental pollution, so the pipeline with pressure sealing design is particularly important. Through regular inspection, maintenance and improvement of the pipeline system to ensure its stable operation under high pressure conditions, it can effectively reduce the probability of accidents and ensure the stability of people's lives and property.

In the field of hydraulic engineering, the pressure sealing design of DAMS, reservoirs and other water conservancy facilities is also very important. Dam is an important facility for water resources utilization, once the leakage will cause serious flood disaster to the downstream area. Therefore, in the design and construction process of the dam, the design requirements with pressure sealing must be taken into account, and the appropriate materials and construction technology must be adopted to ensure that the dam can operate stably under various conditions and prevent the occurrence of leakage accidents.

In general, as an important technical means, the design of sealing with pressure plays a crucial role in the construction and operation of various fields of engineering. Only through scientific design and strict implementation can we ensure the stability and reliability of the system and realize the effective use of resources. Therefore, in engineering practice, it is necessary to attach great importance to the design of sealing with pressure, constantly improve the technical level, and promote the sustainable development of the industry.
