.Waterproof sealed door
.Waterproof sealed door, as the name suggests, is a special door that can function as a waterproof seal. It is mainly used in underground substations, yards and tunnels that require waterproof sealing. Since waterproof airtight doors are mainly used for emergency airtight waterproofing in related places, they must have flexible opening and closing and good sealing.
.Shandong Zhongan Mining Machinery Equipment Co., Ltd. has more than ten years of experience in mining door production, with complete production qualifications and mature production technology. While well controlling the cost of waterproof closed doors, it strictly implements the drawing process standards of the Coal Research Institute , processed according to the drawings to ensure that each set of waterproof closed doors is a qualified product. So what are a set of qualified inspection standards for waterproof closed doors? First of all, the pressure-bearing capacity of the waterproof and airtight door should be up to
the plate of the door leaf should be the national standard
flat steel plate, and the tic-tac-toe rib plate should meet the national standard
thickness.
-. The important component to ensure the flexible opening and closing of waterproof closed doors is the door
-pivot. The waterproof closed doors should be in a normally open state underground and can only be opened under water. It will be closed urgently only when there is a sudden invasion. The weight of the waterproof sealed door leaf is between Flexible opening and closing requirements for emergency closed doors.
- The door pivots of the waterproof doors and sealed doors we produce are all precision cast and have been heat treated to ensure that they will not deform under the weight of the door leaf for a long time. The rolling bearings use high-quality bearings produced in Wafangdian to ensure The door body can be opened and closed flexibly all year round.
- The waterproof closed door leaf is made of flat steel plates, tic-tac rib plates, ring beams, etc., and the strength of the welds must be greater than the base material. The working environment of waterproof sealed doors is relatively harsh, with high air humidity and a certain degree of corrosiveness. This requires the paint surface of waterproof sealed doors to be corrosion-resistant and resistant to a certain degree of acid and alkali.
- Our company has a complete range of mining doors, integrating manufacturer production and sales, eliminating the need for middlemen and allowing customers to enjoy the greatest discounts.
