Description

The quick opening Closure is widely used in containers or equipment, filter separators in gas collection stations, receiving cylinders for long-distance pipelines, etc., which is convenient for production and operation during normal use. However, there will be security risks if it is used improperly or not operated according to the operating procedures.

For example, when the operator opens the quick-opening closure of the filter separator, the pressure in the filter separator is not completely released. Under the action of pressure, the quick opening closure suddenly opens, which poses serious safety risks; Sometimes, when the operator closes the quick opening closure when the blind plate is completely closed, the pressure vessel begins to increase pressure, resulting in an explosion of the pressure vessel, threatening the life and safety of the operator.

Function and effect of quick-opening closure safety interlock alarm device

The invention and use of quick-opening closure safety interlock alarm devices can completely prevent similar accidents. The quick-opening closure safety interlock and synchronous alarm device is developed and designed according to the provisions of the “Pressure Vessel Safety Technical Supervision Regulations.”. The device has the following functions: (1) When the quick opening closure reaches the predetermined closing position, the interlock control function can boost the pressure operation; (2) When the internal pressure of the pressure vessel is completely released and the safety interlock device is removed, the interlock linkage function of the quick opening closure can be opened; (3) With the alarm function synchronized with the above two functions,.

Quick-opening blind plate safety interlock alarm device working principle

The position indicator lights up when the quick opening closure reaches the predetermined closing part. At this time, the safety interlock alarm device can be installed to carry out the booster operation; When the quick opening closure does not reach the predetermined closing position, the position indicator is not bright, and the operator should continue to close the quick opening closure until the predetermined closing position is reached.

During the booster operation, the red light of the interlock indicator is on (when there is pressure in the device, the position indicator light and the interlock indicator light are on at the same time), the wrench jack of the stopper hoisting is red, the safety interlock device is in the locked state, and the blind plate cannot be opened normally. If misoperation loosens the lead screw when the equipment is under pressure, the sound and light alarm will sound.

When the pressure inside the pressure vessel is completely released, the safety interlock device automatically disconnects, the wrench jack becomes a through hole, and the indicator light of the interlock device is extinguished. The interlock device can open the quick-opening closure. When the blind plate is fully opened, the mechanical warning light opens the window in red.

When the quick opening closure is closed to the predetermined position, the position indicator is green; After the pressure is completely released, the indicator light of the interlock device is extinguished to achieve the purpose of a synchronous alarm.

Note: The position indicator light indicates that the blind plate clamp is locked and the predetermined closing position is reached. The position indicator light on the alarm is marked as “locked.” The safety interlock indicator light indicates that there is pressure in the equipment, the interlock device is working, and the safety interlock indicator light on the alarm is marked “working.”.

Use of quick opening closure safety interlock alarm device

Turn the lead screw of the quick-opening closure to close the quick-opening closure. When the position indicator light is on (that is, the interlocking device is in the locking state), it means that the quick opening closure is closed in place and the lead screw can be stopped. At this time, the interlocking device can be installed to perform booster operations.

When the booster is running, the interlocking device indicates that the red light is on (that is, the interlocking device is in the working state), the stop block in the interlocking device is in the position of the wrench jack, and the special wrench cannot be inserted. The safety interlock device is locked, and the quick opening closure cannot be opened normally. At this time, if the wrong operation causes the lead screw when the equipment is under pressure, the sound and light alarm will sound.

When the pressure inside the pressure vessel is ultimately released and the indicator light of the interlock device is extinguished, the stop block in the interlock device returns to its original position, and then the special wrench can be inserted into the wrench jack and the interlock device can be removed.

When the working and locking indicator light is on at the same time, it means that there is pressure inside the pressure vessel, the safety interlock alarm device is in the working state, and any operation on the blind plate is prohibited at this time.
