The manufacture and application of a storage or distribution device for a gas or liquid relates to a sealing element of a pressure vessel or pipe, in particular to a plug type quick opening blind plate. This kind of fast opening blind plate is mainly used for oil and gas pipeline, pigging ball cylinder end cap of a blind plate element, the existing structure of the complex and difficult process, so the sealing performance is poor; some parts due to corrosion broken and cannot switch, hoist and safety device is complex. The cost is high, the switch is not flexible, not safe. The key feature of this device is the switch is flexible, fast, and easy to open and close, safe and reliable blind plate - Insert button type fast opening blind plate.

Buckle type fast opening blind plate technology solutions is a branch of the ear and lower lug on the fixed cylinder, one end of the bracket by adjusting the screw fixation in the upper and lower support lug, and the other end of the rotating arm is hinged, the other end of the rotary arm is arranged relative to the swing shaft; the other blind end and the core shaft cover is connected in the blind plate is fixed on the handle seat. A starting in screw connection lugs by thread, the blind plate is arranged on the baffle plate in the corresponding starting; blind plate and cylinder gap is arranged inside the safety board, safety board by the pressure relief bolt is fixed on the blind plate, the bolt has opened unloading pressure vent connected with the exhaust hole; a handle is fixed on the handle seat, provided with circular holes can be inserted into the boosting rod; on both sides of the cylinder body and the handle seat are respectively provided with open and close the retaining pin retaining pin.

This device is simple, and start saving, opening and closing fast, convenient, accurate positioning, safe and reliable operation, has the advantages of simple structure, convenient processing, good sealing performance and low cost; equipment is mainly used in petroleum, natural gas pipeline, pigging ball cylinder end cover, is conducive to rapid pigging operation, improve the pipeline transportation capacity, reduce energy consumption, to ensure the safe operation of pipelines, but also can be widely used in chemical industry, national defense, medical treatment, drainage and other industrial fields in need of quick opening and closing pressure pipe or container.
