Therefore, the existing pressure container entrance door has the problem of low safety.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a higher pressure vessel of security enters people's door. The utility model has the advantages of high safety.
The technical scheme of the utility model: a pressure vessel entrance door with higher safety comprises a connecting column which is convexly arranged at the top end of a pressure vessel, wherein an entrance is arranged in the middle of the connecting column; the connecting column is sleeved with a connecting sleeve through threads, the side surface of the connecting column is provided with a pressure relief hole, and the side surface of the connecting sleeve is provided with a through hole; the top end of the connecting sleeve is provided with a cover plate, and a plurality of bolts are connected between the cover plate and the connecting sleeve.
In the pressure vessel entrance door with higher safety, the top end of the pressure vessel is provided with the connecting hole at the position corresponding to each bolt.
In the pressure container entrance door with higher safety, the clamping ring is arranged at the top end of the connecting column, and the clamping groove is arranged at the position on the connecting sleeve corresponding to the clamping ring.
In the pressure container entrance door with high safety, the whistle is arranged at the through hole.
Compared with the prior art, the utility model improves the existing pressure container entrance door, and the connecting column is arranged at the top end of the pressure container, is hollow and is directly communicated with the inside of the pressure container, so that the middle part of the connecting column is the entrance; a connecting sleeve is sleeved on the outer side of the connecting column and is in threaded connection with the connecting column, and a sealing ring is fixed at the bottom end of the connecting sleeve to prevent pressure release at the threaded part; the connecting sleeve rotates on the connecting column, so that the pressure relief hole is opposite to the through hole, the inside of the pressure container is communicated with the outside, the pressure of the pressure container is relieved, and the operation is convenient; in the pressure relief process, a plurality of bolts are still connected between the connecting sleeve and the cover plate at the top end, so that the cover plate at the top end of the connecting sleeve can be prevented from being pushed away to hurt workers, and the safety is high; meanwhile, the gravity of the connecting sleeve and the cover plate can prevent the connecting sleeve from being pushed open under the internal pressure of the pressure container, and the safety is further improved. In addition, the top end of the pressure container is provided with a connecting hole corresponding to the position of each bolt, so that the cover plate can be directly connected with the pressure container when the pressure container is normally used, and the cover plate and the connecting sleeve are prevented from being pushed out; the clamping ring at the top end of the connecting column is matched with the clamping groove on the connecting sleeve, so that the connecting sleeve can only ascend on the connecting column for a moving distance, the connecting sleeve is prevented from being pushed out of the connecting column, and the safety of equipment is improved; in the pressure relief process of the pressure container, the whistle can make sound by the air flow at the position of the through hole, so that a worker can better judge the pressure relief condition and the operation is convenient. Therefore, the utility model discloses not only can have higher security, still have the more convenient advantage of operation.

The labels in the figures are: 1-pressure container, 2-connecting column, 3-inlet, 4-connecting sleeve, 5-pressure relief hole, 6-through hole, 7-cover plate, 8-bolt, 9-connecting hole, 10-clamping ring, 11-clamping groove and 12-whistle.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A pressure vessel entrance door with high safety is formed as shown in figures 1 and 2 and comprises a connecting column 2 which is convexly arranged at the top end of a pressure vessel 1, wherein an entrance 3 is arranged in the middle of the connecting column 2; a connecting sleeve 4 is sleeved on the connecting column 2 through threads, a pressure relief hole 5 is formed in the side face of the connecting column 2, and a through hole 6 is formed in the side face of the connecting sleeve 4; the top end of the connecting sleeve 4 is provided with a cover plate 7, and a plurality of bolts 8 are connected between the cover plate 7 and the connecting sleeve 4.
A connecting hole 9 is formed in the position, corresponding to each bolt 8, of the top end of the pressure container 1; a clamping ring 10 is arranged at the top end of the connecting column 2, and a clamping groove 11 is arranged on the connecting sleeve 4 at a position corresponding to the clamping ring 10; a whistle 12 is arranged at the through hole 6.
The working principle is as follows: when the pressure vessel 1 needs to be overhauled, most of pressure in the pressure vessel 1 is exhausted through the pressure exhaust of the pressure vessel 1, and then a worker screws all the bolts 8 on the cover plate 7 out of a part upwards, so that the bottom ends of the bolts 8 are separated from the connecting holes 9 at the top end of the pressure vessel 1; at the moment, the connecting sleeve 4 is rotated again, so that the connecting sleeve 4 moves upwards along the connecting column 2 through threads, when the through hole 6 in the connecting sleeve 4 is aligned with the pressure relief hole 5 in the connecting column 2, the pressure inside the pressure container 1 is further relieved until the pressure is consistent with the external atmospheric pressure, the air flow at the through hole 6 can make the whistle 12 sound in the pressure relief process, and when the whistle 12 does not make any sound any more, the pressure relief is finished; a clamping ring 10 is fixed at the top end of the connecting column 2 (for installation convenience, the clamping ring 10 can be welded after the connecting sleeve 4 is installed), a clamping groove 11 is arranged on the connecting sleeve 4, the clamping groove 11 is vertically clamped with the clamping ring 10, the connecting sleeve 4 can be prevented from being pushed out of the connecting column 2 upwards by overlarge pressure in the pressure container 1 (the connecting sleeve 4 and the cover plate 7 can also guarantee to a certain extent that the connecting sleeve 4 cannot be separated from the connecting column 2), and the safety is high; and finally, screwing out the bolt 8 on the cover plate 7, so that the cover plate 7 is separated from the connecting sleeve 4, and a worker enters the pressure container 1 through the inlet 3 in the middle of the connecting column 2 to overhaul.
