DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1, reference Figure 1 , is the first embodiment of the present invention, which provides an automatic pressure relief air storage tank, comprising, an air storage tank 100, the air storage tank 100 comprising a tank body 101 for storing compressed air, an output port 102 provided on the tank body 101 for outputting compressed air, an input port 103 provided on the tank body 101 for delivering compressed air to the tank body 101, the input port 103 on the tank body 101 is located lower than the output port 102, and is used to reduce air flow pulsation in the pipeline, making the air flow more stable, thereby stabilizing the pressure of the pipe network system and reducing liquid reflux, and a drain valve 104 provided on the tank body 101 for discharging condensed water in the tank body 101; The automatic pressure relief unit 200 includes a connecting component 201 arranged on the tank body 101, which is used to connect the tank body 101 and relieve the pressure of the tank body 101 when the tank body 101 is over-pressured; a pressure relief adjustment component 202 arranged on the connecting component 201, which is used to control the closure of the tank body 101; and a pressure relief reminder component 203 arranged on the connecting component 201, which is used to control the flow path of the gas when the device is relieved of pressure and to remind the staff.

[0030] In summary, when the device is used, the device is connected to the air compression system through the output port 102 and the input port 103. At this time, the pressure relief adjustment component 202 is controlled to close the tank body 101 and adjust it to a reasonable pressure relief value. At this time, the air compression system can be started to work; When the device is over-pressurized or compressed air leaks due to material fatigue, the compressed air will push open the pressure relief adjustment component 202. At this time, the connecting component 201 is connected to the inner wall of the tank body 101, and the compressed air flows out from the connecting component 201 and flows to the outside through the pressure relief reminder component 203. In this process, when the compressed air flows through the pressure relief reminder component 203, a loud noise will be emitted, and the pressure relief reminder component 203 will be damaged, reminding the staff that a leak has occurred.

[0031] Example 2, reference Figure 1-Figure 7 , which is the second embodiment of the present invention, and is different from the previous embodiment in that: the closure of the automatic pressure relief unit 200 is controlled to slow down the speed of material fatigue. Compared with embodiment 1, further, the connecting component 201 includes a connecting pipe 201a disposed on the tank body 101, a connecting cavity 201b disposed in the connecting pipe 201a for communicating with the tank body 101, a channel for compressed air flow, and a connecting wall 201c disposed in the connecting pipe 201a, which is used to cooperate with the pressure relief adjustment component 202 to strengthen the sealing of the tank body 101 to prevent leakage when the device is used.

[0032] Among them, the pressure relief adjustment component 202 includes a closing piece 202a arranged on the connecting pipe 201a, which is used to close the flow channel when the compressed air leaks, a pressure piece 202b arranged on the connecting pipe 201a, which is used to control the force of the closing piece 202a to close the tank body 101, so as to achieve the purpose of controlling the rated pressure of the tank body 101 and adapting to compressors of different powers, and an adjusting piece 202c arranged on the connecting pipe 201a, which is used to control the thrust of the pressure piece 202b.

[0033] The sealing member 202a includes a sealing head 202a-1 disposed on the connecting pipe 201a, used to abut against the tank body 101 to close the passage for the compressed air to be released, a sealing block 202a-2 disposed on 201a-1 and abutting against the connecting wall 201c, used to further enhance the sealing effect and prevent the normal use of the device from being affected, and a connecting shaft 202a-3 disposed on the sealing block 202a-2, used to cooperate with the pressing member 202b to move; The cross-sectional area of ​​the plugging head 202a-1 gradually decreases from one end close to the tank body 101 to the other end. The tank body 101 is provided with a plugging groove 101a that matches the plugging head 202a-1, so that the contact area with the tank body 101 can be increased to enhance the sealing effect. A first sealing ring a is provided on the sealing head 202a-1 to abut against the sealing groove 101a, and a second sealing ring b is provided on the sealing block 202a-2 to abut against the connecting wall 201c, so as to close the small gap between the sealing head 202a-1 and the sealing groove 101a and enhance the sealing performance.

[0034] The pressing member 202b includes a connecting piece 202b-1 disposed on the blocking block 202a-2, a pressing spring 202b-2 disposed on the connecting piece 202b-1, and a pushing block 202b-3 disposed on the pressing spring 202b-2. The connecting piece 202b-1 is used to cooperate with the pushing block 202b-3 to press the connecting shaft 202a-3 through the pressing spring 202b-2, so that the blocking head 202a-1 is tightly against the blocking groove 101a, and the blocking block 202a-2 is tightly against the connecting wall 201c. The push block 202b-3 has a polygonal shape, and the connecting cavity 201b fits the shape of the push block 202b-3, which plays a role of limited sliding, preventing the pressure spring 202b-2 from twisting and affecting the pressure on the blocking block 202a-2.

[0035] The adjusting member 202c includes a threaded shaft 202c-1 disposed on the connecting shaft 202a-3, used to support the connecting shaft 202a-3 and the pushing block 202b-3, one end of the threaded shaft 202c-1 passes through one end of the connecting pipe 201a from the connecting cavity 201b, and is rotatably connected to the connecting pipe 201a, a knob 202c-2 disposed on the threaded shaft 202c-1, used to control the rotation of the threaded shaft 202c-1, and a sliding cavity 202c-3 disposed in the threaded shaft 202c-1 to cooperate with the connecting shaft 202a-3, used to cooperate with the back and forth movement of the connecting shaft 202a-3 to facilitate the outflow of compressed air when the compressed air inside the tank body 101 is over-pressured and the plugging head 202a-1 is pushed open; The pushing block 202b-3 is provided with an internal thread c that cooperates with the threaded shaft 202c-1, which is used to cooperate with the rotation of the threaded shaft 202c-1 to move back and forth on the threaded shaft 202c-1, push and pull the pressure spring 202b-2, control whether the blocking block 202a-2 is abutted and sealed with the connecting wall 201c, and the size of the abutment pressure, thereby controlling the maximum pressure of the compressed air in the tank body 101, thereby achieving the purpose of adjusting the amount of compressed air contained.

[0036] The rest of the structure is the same as that of Example 1.

[0037] In summary, after the device is connected to the air compression system through the output port 102 and the output port 102, the knob 202c-2 is turned to drive the threaded shaft 202c-1 to rotate. At this time, the pushing block 202b-3 moves on the threaded shaft 202c-1, compressing the pressing spring 202b-2, and pushing the blocking block 202a-2 to abut against the connecting wall 201c through the connecting piece 202b-1. At this time, the blocking head 202a-1 abuts against the blocking groove 101a. At this time, the first sealing ring a and the second sealing ring b further enhance the sealing effect. At this time, the knob 202c-2 is continued to be turned to continue to strengthen the thrust of the pushing block 202b-3 until it increases to the target value. At this time, the air compression system can be started. At the same time, the pressure of the connecting piece 202b-1 on 201a-2 can be controlled by turning the knob 202c-2, thereby controlling the pressure of the compressed air in the tank body 101. The pressure can be matched with different types of air compression systems in turn to improve the applicability of the device; When the device is not used or is idle, the compressed air in the tank body 101 is released through the output port 102, and the condensed water in the tank body 101 is drained through the drain valve 104. At this time, the knob 202c-2 is turned to drive the threaded shaft 202c-1 to reverse. At this time, the push block 202b-3 moves toward the direction close to the knob 202c-2. At this time, the pressure spring 202b-2 is released as the pressure spring 202b-2 moves. At this time, the pressure of the connecting piece 202b-1 on 201a-2 gradually decreases until the pressure spring 202b-2 is completely released. At this time, the blocking block 202a-2 has no pressure on the connecting wall 201c, preventing the device parts from being under high pressure for a long time and accelerating material fatigue.

[0038] Example 3, reference Figure 1-Figure 9 , which is the second embodiment of the present invention, and is different from the previous embodiment in that: when the tank 101 leaks, the staff is reminded. Compared with embodiment 1, further, the pressure relief reminder component 203 includes an alarm 203a arranged on the connecting pipe 201a, which is used to make a sound when compressed air leaks to remind the staff, a protective cover 203b arranged on the connecting pipe 201a, which is used to protect the alarm 203a and prevent the alarm 203a from being blocked, and a sealing film 203c arranged on the connecting pipe 201a, which is used to rupture when impacted by the leaked compressed air, so as to visually remind the staff.

[0039] Among them, the alarm component 203a includes an air intake chamber 203a-1 arranged on the connecting pipe 201a, the air intake chamber 203a-1 is connected with the connecting chamber 201b and is used for the flow of compressed air, an exhaust port 203a-2 arranged on the connecting pipe 201a and is used for the discharge of compressed air, a resonance chamber 203a-3 arranged on the connecting pipe 201a and is used for the entry of compressed air to produce backflow, and a dividing piece 203a-4 arranged on the exhaust port 203a-2 and is used to cut the compressed air and separate the airflow into two alternately split vortices to form air layer pulsation, and then generate and amplify sound through the resonance of the resonance chamber 203a-3, so as to achieve the purpose of reminding the staff to come and check.

[0040] The air inlet cavity 203a-1, the exhaust port 203a-2, and the resonance cavity 203a-3 are connected to each other, and the exhaust port 203a-2 is connected to the outside.

[0041] Among them, the dividing piece 203a-4 is set to be in an inclined state, with the side close to the air inlet cavity 203a-1 being at a low position, and the cross-sectional area of ​​the dividing piece 203a-4 gradually decreases towards the air inlet cavity 203a-1, so as to facilitate the cutting of the airflow and stably generate vortices to ensure that the sound can be emitted normally.

[0042] The rest of the structure is the same as that of Example 2.

[0043] In summary, when the tank body 101 has overpressure or material fatigue causing compressed gas leakage, at this time, the compressed air will push open the sealing head 202a-1 and enter the connecting cavity 201b from the sealing groove 101a. At this time, the compressed air enters the air inlet cavity 203a-1. When it is discharged through the resonance cavity 203a-3, the compressed air is divided by the dividing piece 203a-4 and divided into two air flows. One of the air flows enters the resonance cavity 203a-3, forming a backflow and colliding with the other air flow. After being amplified by the resonance cavity 203a-3, a violent sound will be generated, reminding the staff that the device has leaked. At this time, when the compressed air rushes out through the exhaust port 203a-2, it will break the sealing film 203c, giving the staff a visual reminder.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
