Information

  With the development of science and technology, people pay more and more attention to ship manufacturing technology and safety issues. As an important means of marine transportation, ships also need to install some facilities to ensure safety. Marine fire-proof hydraulic door is one of the most important facilities. Next, Nanjing Jingyun ship accessories Co., Ltd. will introduce you to understand the working principle of marine fire-proof hydraulic door?

  

船用防火液压门的工作原理有哪些?

 

  1. The working principle of marine fire-proof hydraulic door is: when the door is opened, the door body drives the connecting rod, at the same time, the transmission gear rotates, so that the rack plunger moves to the right. As the plunger moves to the right, the spring is compressed and the hydraulic oil is pressurized. The valve ball of the plunger is opened under the influence of oil pressure, and the right hydraulic oil flows into the left side from the check valve. After the completion of the door opening, because the spring is compressed during the opening process, it will rebound and push the plunger to the left, making the door closer connecting rod and transmission gear rotate, finally closing the door and completing the work once.

2. When the spring is released, because the hydraulic oil compressed to the left of the door closer will close the check valve, the hydraulic oil will flow out through the gap between the plunger and the housing, and return to the right through the hole on the plunger. Therefore, the hydraulic oil blocks the release of the spring, that is to say, the buffer effect is caused by throttling, and the speed of closing the door is effectively controlled. The throttle valve on the valve body can be adjusted to control different closing speeds. Although the size and structure of door closer produced by different manufacturers are different, the principle is the same, which can effectively ensure safety. The components of marine fire-proof hydraulic door include supporting guide, check valve, transmission gear, return spring, rack plug, sealing ring and connecting rod. The connecting rod and the housing can fix the door closer and connect the door leaf and the door frame.
What are the working principles of marine fire-proof hydraulic doors? After a brief introduction, I believe you have a general understanding of the working principles of marine fire-proof hydraulic doors. Marine fire-proof hydraulic door can not only close the door automatically, but also protect the door frame and the door body, which has become an important part of modern ship safety facilities.
