Description

Vertical compression type push-pull sealing door Technical Field The invention relates to the technical field of cabin door sealing, in particular to a vertical compression type sliding sealing door. Background The design of the sealing structure is an important part of the pressure vessel and the oxygen cabin, and the common sealing forms are forced sealing and self-tightening sealing. In low and medium pressure containers, a forced sealing structure, such as a flange connection structure, is generally adopted, and is characterized in that a gasket pretightening force is generated by means of a tightening bolt, so that initial sealing is achieved, when the pressure is increased, the gasket can produce enough resilience force to achieve sealing capability under an operation working condition, and self-tightening sealing is generally used in the sealing structure of a high pressure container, but under the high pressure working condition, the service life of a sealing element is low, and the sealing performance is unreliable. Along with the development of the pressure vessel in large size and the application field, the sealing gap between the door plate and the door frame is uneven due to the influence of processing errors and assembly precision, so that the problem of poor sealing can be caused. In order to reduce the occupied space of the door body in an open state as much as possible, the existing sliding door in the market adopts the existing sliding door structure, and mainly has the following problems that firstly, the sliding door has no sealing effect, only has a switching effect, after the sliding door is closed, a door plate and a door frame have gaps with different sizes, secondly, the sliding door has a sliding track, great inconvenience and potential safety hazards are brought to walking and transportation of people, particularly, the sliding door is used as a pressure container of a medical air pressurized oxygen cabin, the sliding door is extremely inconvenient for the old, the weak, the sick, the disabled and the stretcher to enter and exit due to the existence of a lower slideway, and the potential safety hazard is extremely great, and thirdly, the sliding door is sealed by manual or other locking modes after the sliding door is closed, so that the sealing effect is poor and the labor is consumed. Since the sealing door is a door for preventing gas, liquid or solid particles from leaking from one area to another, it is widely used in various fields such as industrial equipment, medical equipment, food processing, etc., such as dust-free rooms, medical oxygen tanks, food processing rooms, etc. The sliding sealing door is characterized in that a door opening mode is a sliding type, sealing strips and sealing surfaces of the sliding sealing door are designed to be very close or even overlapped in order to ensure the sealing performance of a cabin door, so that a door body and the sealing strips are easily scratched in the process of closing the door and the door, the sealing strips are worn, deformed and even fall off, and the resistance is overlarge in the process of opening and closing the door, so that the problem of noise is easily caused.
