1. Structure
The Quick Opening Closure Lock Ring is an important component of the pressure vessel. It has many advantages. For example, the opening and closing speeds are fast, the operation is smart, simple, safe, and reliable. The quick-opening blind plate comprises a high neck, a door cover, a ring lock, and a locking mechanism. There are also sealing rings and safety interlocks. The inner circle of the high neck and the outer circle of the door cover have ring grooves. Half of the ring lock is embedded in the high neck groove during operation.

And the other half is embedded in the door cover groove. Which thereby locks the high neck and the door cover. When opening the door, tighten the ring lock through the locking mechanism with a booster rod. Because this makes its outer ring smaller than the outer diameter of the door cover. So that the door cover can be opened. So its operation is very convenient. The seal ring is designed with a reasonable structure and excellent materials. This ensures product sealing performance. In addition, it is also equipped with a safety interlock device with an alarm function. It can sufficiently ensure safety and reliability.

Quick Opening Closure
2. Overview
Pressure vessels need to be cleaned, unblocked, inspected, and cleaned on a daily basis. The quick-opening blind plate is a fixed quick-opening device at the nozzle. The filter separator and launcher of many equipments are equipped with quick-opening blind plates. In a short, if you have any other questions, please contact our professionals to answer them for you.

3. Operating procedures
1. Inspection and preparation
(1) Check that the Quick Opening Closure and auxiliary devices are in good condition.
(2) Confirm the opening and closing status of each valve before opening the blind plate.
(3) The operator shall vent the natural gas in the receiver and launcher first. Ensure that the ball cylinder is not under pressure. That is, the indication of the pressure indicating device on the equipment is zero. And keep the vent valve fully open;
(4) Prepare special tools.

2. Opening of lock ring quick opening blind plate
(1) Open the vent valve and blowdown valve of the pressure vessel. This reduces the pressure in the cylinder to zero;
(2) Unscrew the bleeder valve. Remove the safety card;
(3) Turn the screw rod clockwise. This separates the pressure ring to a certain position. It completely separates the teeth of the left and right pressure rings;
(4) Gently pull the handle of the blind plate cover. We can open the blind plate.


3. Closing of Quick Opening Closure
(1) After the dirt in the sealing surface, the sealing groove and upper and lower pressure ring handles are completely removed. Apply antirust grease;
(2) Push the blind plate cover into the press ring completely;
(3) Turn the screw rod counterclockwise. Lock the blind plate cover;
(4) Install the safety card. Tighten the vent valve;
(5) Close the vent valve and blowdown valve of the pressure vessel.

4. Precautions for operation and maintenance of quick opening blind plate
No one is allowed to stand on the front and inside of the quick-opening blind plate;
The person using the blind plate must understand the structure and operating procedures of the blind plate;
The air valve must be opened before the blind cover is opened. After the pressure in the container drops to zero. Only then can we open the blind plate;
Before pressurizing the pressure vessel with the blind plate. The locking plate of the blind plate must be installed first.
After putting into use, it is not allowed to knock and collide with all main pressure-bearing parts;
(1) The surface of the blind plate must always be kept intact and clean;
(2) Regularly inspect the main pressure-bearing parts of the blind plate (such as the blind plate cover and cylinder surface). If we find severe corrosion or cracks. Find out the reason in time. And properly handle it;
(3) After each use, the sealing rubber ring and sealing groove shall be cleaned, inspected, and lubricated.
