Quick opening blind plate design and manufacture should follow the technical specifications and related standards requirements. Strength calculation and structural design according to GB150 regulations, and it is necessary to analyze the design or other such as stress testing. Performance requirements in the design temperature, design pressure to meet the requirements of the strength requirements, and corrosion resistance requirements, should ensure that the use of safe and reliable. Can withstand the shock caused by the pipeline cleaning device, but not the occurrence of safety accidents. Fast opening blind plate, the fast opening blind plate should be open and close flexible, and with a safe locking device, to ensure that the pressure can not be opened. After the pressure relief is zero and start the safety locking device, fast opening blind plate can be opened. Safety locking device is not installed, the device can not be boosted. And there are warning signs in the right place. Quick opening blind plate should be operated with the hand wheel or special wrench to ensure open and close flexible, convenient, reliable sealing, no leakage. When the quick opening blind plate is opened, the positioning device is provided with a fixed door lock to prevent accidental closing. The closing mechanism and the rotating arm of the quick opening blind plate shall be fixed on the edge flange of the blind plate, and the fixed device can not be fixed on the cylinder body.
Safety facilities shall be provided to prevent accidental opening of the opening of the blind plate before the opening of the tube to be pressed. The annular sealing ring shall ensure that the design conditions and the following shall be sealed, reliable and free from leakage. The annular sealing ring of the artificial rubber should be able to withstand the pressure of the explosion of the medium, and meet the requirements of conveying fluid in the design conditions. The material of the sealing ring should be compatible with the conveying fluid and the equipment is beautiful in appearance, and can be used in all weather condition in the installation environment.
