Description
Technical Field
[0001] This utility model relates to the field of depressurization vacuum buffer tank technology, and in particular to a depressurization vacuum buffer tank. Background Technology
[0002] Buffer tanks are primarily used in various systems to buffer pressure fluctuations, making the system operate more smoothly. The buffering performance of a buffer tank is mainly achieved by compressing the air inside the tank. Buffer tanks come in two types: diaphragm-type and air-bladder-type, and are widely used in water supply equipment and central air conditioning systems, among other applications.
[0003] The inventors discovered during daily use of the buffer tank that the buffer tank is usually connected to the air pump via a flange. However, the flange needs to be installed diagonally. If it is not installed diagonally, problems such as tilting and misalignment can easily occur, which can cause problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a decompression vacuum buffer tank.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a depressurization vacuum buffer tank, comprising a buffer tank, a connecting pipe fixedly connected to the side of the buffer tank, a convenient connection device provided on the surface of the connecting pipe, the convenient connection device comprising a retaining ring fixedly connected to the surface of the connecting pipe, and an air tube sleeved on the surface of the connecting pipe.
[0006] The aforementioned components achieve the following effects: the retaining ring allows the air tube to be secured to the surface of the connecting tube, thus achieving a fixed function. When the buffer tank is needed, it is connected to the air pump, allowing gas to first fill the space inside the buffer tank. When the air pump starts, the gas inside the buffer tank flows out first. As the gas level inside the buffer tank decreases, gas rushes into the buffer tank from the connecting tube. When the air pump stops, the gas flows back into the buffer tank, thereby achieving a pressure reduction effect.
[0007] Preferably, an L-shaped rod is fixedly connected to the surface of the trachea, a trapezoidal block is fixedly connected to the surface of the L-shaped rod, and a circular plate is fixedly connected to the surface of the connecting tube.
[0008] The effect achieved by the above components is as follows: under the action of the trapezoidal block and the circular plate, the connecting pipe is inserted into the interior of the air intake pipe, thereby achieving a fixing effect; under the action of the trapezoidal block, the circular plate can be easily locked onto one side of the trapezoidal block, thereby achieving a fixing effect.
[0009] Preferably, a washer, which is a rubber ring, is fixedly connected to the side of the circular plate.
[0010] The effect achieved by the above components is that, under the action of the washer, the trapezoidal block and the circular plate will not collide directly, thus avoiding the phenomenon of rigid contact.
[0011] Preferably, a sealing ring is fixedly connected to one end of the connecting pipe, and the sealing ring is a deformable rubber ring.
[0012] The effect achieved by the above components is that, under the action of the sealing ring, gas will not leak from between the gas pipe and the connecting pipe.
[0013] Preferably, the surface of the L-shaped rod is threaded with a bolt, which is inserted into the interior of the connecting pipe.
[0014] The aforementioned components achieve the following effects: The bolts securely fix the air tube to the surface of the connecting tube. When connecting the tubes, the air tube is fitted onto the surface of the connecting tube, and the retaining ring secures it, thus achieving a fixed position. The sealing ring prevents gas leakage between the air tube and the connecting tube. When the air tube is fitted onto the surface of the connecting tube, the trapezoidal block allows the circular plate to easily engage with one side of the trapezoidal block, achieving a fixed position. The washers prevent direct impact between the trapezoidal block and the circular plate, avoiding rigid contact. The bolts are then screwed into the connecting tube to fix the air tube to its surface, facilitating connection.
[0015] Preferably, the surface of the buffer tank is provided with an anti-collision device, the anti-collision device including an anti-collision ring sleeved on the surface of the buffer tank, and an airbag is provided inside the anti-collision ring.
[0016] The effect achieved by the above components is that, under the action of the airbag inside the anti-collision ring, the buffer tank will not deform or be damaged after being impacted, thus achieving the anti-collision function.
[0017] Preferably, a rectangular plate is fixedly connected to the surface of the anti-collision ring, and a pad, which is a rubber plate, is fixedly connected to the surface of the rectangular plate.
[0018] The effect achieved by the above components is that, under the action of the pad, the rectangular plates will not make rigid contact.
[0019] Preferably, the rectangular plate has a through groove on its surface, a screw is inserted into the through groove, and a nut is fixedly connected to one end of the rectangular plate, with the nut and screw threaded together.
[0020] The effect achieved by the above components is as follows: under the action of screws and nuts, the rectangular plates are fixed together, thereby achieving the function of fixing the anti-collision ring. When the buffer tank needs to be protected, the anti-collision ring is snapped onto the surface of the buffer tank, and the screws are inserted into the through groove. Under the action of nuts and screws, the rectangular plates move relative to each other. Under the action of the pad, the rectangular plates do not make rigid contact with each other, thereby fixing the anti-collision ring to the surface of the buffer tank, thus achieving the function of the buffer tank preventing collisions.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, a convenient connection device is provided. When connecting the pipes, the air pipe is sleeved on the surface of the connecting pipe. Under the action of the retaining ring, the air pipe can be clamped on the surface of the connecting pipe, thus achieving a fixing effect. Under the action of the sealing ring, gas will not leak from the air pipe and the connecting pipe. When the air pipe is sleeved on the surface of the connecting pipe, under the action of the trapezoidal block, the circular plate can be easily clamped on one side of the trapezoidal block, thus achieving a fixing effect. Under the action of the washer, the trapezoidal block and the circular plate will not directly collide, avoiding the phenomenon of rigid contact. The bolt is screwed into the inside of the connecting pipe, thus fixing the air pipe on the surface of the connecting pipe, thereby achieving a convenient connection effect. This solves the problem that buffer tanks are usually connected by flanges and are prone to tilting and misalignment if diagonal fixing is not performed. Attached Figure Description

[0027] Example 1, such as Figure 1 A pressure-reducing vacuum buffer tank 1 includes a buffer tank 1, and a connecting pipe 4 is fixedly connected to the side of the buffer tank 1.
[0028] Working principle: When buffer tank 1 is needed, it is connected to the air pump, so that the gas first fills the space inside buffer tank 1. When the air pump is started, the gas inside buffer tank 1 flows out first. When the gas inside buffer tank 1 decreases, the gas rushes into the interior of buffer tank 1 through the connecting pipe 4. When the air pump stops, the gas flows back into the interior of buffer tank 1, thereby achieving the function of depressurization.
[0029] Reference Figure 2 The surface of the connecting pipe 4 is provided with a convenient connection device 2, which includes a retaining ring 21 fixedly connected to the surface of the connecting pipe 4. An air tube 22 is sleeved on the surface of the connecting pipe 4. An L-shaped rod 24 is fixedly connected to the surface of the air tube 22. A trapezoidal block 25 is fixedly connected to the surface of the L-shaped rod 24. A circular plate 27 is fixedly connected to the surface of the connecting pipe 4. A washer 28, which is a rubber ring, is fixedly connected to the side of the circular plate 27. A sealing ring 23, which is a deformable rubber ring, is fixedly connected to one end of the connecting pipe 4. A bolt 26 is threadedly connected to the surface of the L-shaped rod 24 and is inserted into the interior of the connecting pipe 4.
[0030] Working principle: When connecting the connecting pipe 4, the air pipe 22 is fitted onto the surface of the connecting pipe 4. Under the action of the retaining ring 21, the air pipe 22 can be locked onto the surface of the connecting pipe 4, thus achieving a fixing effect. Under the action of the sealing ring 23, gas will not leak from the air pipe 22 and the connecting pipe 4. When the air pipe 22 is fitted onto the surface of the connecting pipe 4, under the action of the trapezoidal block 25, the round plate 27 can be easily locked onto one side of the trapezoidal block 25, thus achieving a fixing effect. Under the action of the washer 28, the trapezoidal block 25 and the round plate 27 will not directly collide, avoiding the phenomenon of rigid contact. The bolt 26 is screwed into the interior of the connecting pipe 4, thus fixing the air pipe 22 onto the surface of the connecting pipe 4, thus achieving a convenient connection effect.
[0031] Reference Figure 3 The surface of the buffer tank 1 is provided with an anti-collision device 3. The anti-collision device 3 includes an anti-collision ring 31 sleeved on the surface of the buffer tank 1. An air bladder is provided inside the anti-collision ring 31. A rectangular plate 33 is fixedly connected to the surface of the anti-collision ring 31. A pad 32 is fixedly connected to the surface of the rectangular plate 33. The pad 32 is a rubber plate. A through groove is provided on the surface of the rectangular plate 33. A screw 35 is inserted into the through groove. A nut 34 is fixedly connected to one end of the rectangular plate 33. The nut 34 and the screw 35 are threaded together.
[0032] Working principle: When it is necessary to protect the buffer tank 1, the anti-collision ring 31 is snapped onto the surface of the buffer tank 1, and the screw 35 is inserted into the through groove. Under the action of the nut 34 and the screw 35, the rectangular plate 33 moves relative to each other. Under the action of the pad 32, the rectangular plate 33 will not have rigid contact, thereby fixing the anti-collision ring 31 to the surface of the buffer tank 1, thus achieving the anti-collision function of the buffer tank 1.
