A corrugated sleeve is provided in the middle of the U-shaped tube of the utility model, and the angle and direction of the U-shaped tube can be adjusted through the corrugated sleeve, so that it can change the shape of the two assembled pressure vessel bodies, and it is more flexible to use.

[0004] However, the device still has some shortcomings: the device lacks the function of absorbing and buffering the vibrations generated during the operation of the pressure vessel. Utility Model Content

[0005] The utility model aims to provide a U-shaped connected pressure container in view of the problems existing in the background technology.

[0006] The technical solution of the utility model is a U-shaped connected pressure container, which comprises a pressure tank, a rotatably connected sleeve and a sliding groove arranged in the sleeve.

The inner diameter of the exhaust pipe is much larger than the inner diameter of the intake pipe. When the spring is compressed, the air is exhausted in the slide groove. At this time, the air in the slide groove is quickly discharged along the exhaust pipe and the intake pipe at the same time. Then, when the spring stretches and restores its initial state, the outside air can only enter the slide groove along the intake pipe. The air that slowly enters the slide groove makes the spring take significantly longer to recover. Therefore, this structure prevents the spring from repeated expansion and contraction deformation, thereby achieving the effect of rapid vibration absorption and buffering.

DETAILED DESCRIPTION

[0025] Embodiment 1

[0026] like Figure 1-Figure 4 As shown, the utility model proposes a U-shaped connected pressure vessel, comprising a pressure tank 1, a piston rod 7, a tensioning assembly 9, an exhaust pipe 10, an air inlet pipe 11 and an elevation adjustment assembly. The pressure tank 1 is detachably provided with an end cover 4 that seals with its opening, and the pressure tank 1 is connected to the end cover 4 by a plurality of bolts and nuts that are distributed in a ring array around the axis of the end cover 4. The pressure tank 1 is rotatably connected to a sleeve 6, and a slide groove is arranged in the sleeve 6. An exhaust hole and an air inlet hole are arranged on the sleeve 6, and the inner diameter of the exhaust hole is larger than the inner diameter of the air inlet hole, and the exhaust hole and the air inlet hole are both connected with the slide groove along the upper side. The piston rod 7 is inserted into the slide groove and slidably connected with its inner wall, and the bottom of the piston rod 7 is connected to the bottom plate 8. The tensioning assembly 9 is located in the slide groove, and the tensioning assembly 9 includes a slide rod and a spring, the top end of the slide rod is connected to the upper wall of the slide groove, and the slide rod is inserted into the piston rod 7 and slidably connected with it. The spring is sleeved on the outside of the slide rod, and the two ends of the spring are respectively in contact with the upper wall of the slide groove and the upper surface of the piston rod 7. The exhaust pipe 10 is connected to the sleeve 6 and covered on the outside of the exhaust hole, and a one-way valve is arranged inside the exhaust pipe 10 to prevent the outside air from entering the chute along its outlet. The air intake pipe 11 is connected to the sleeve 6 and covered on the outside of the air intake hole, and the inner diameter of the air intake pipe 11 is smaller than the inner diameter of the exhaust pipe 10, and a dustproof net is arranged inside the air intake pipe 11 to prevent dust from entering the inside of the chute. The elevation adjustment component includes but is not limited to a hydraulic cylinder 12, the cylinder barrel of the hydraulic cylinder 12 is rotatably connected to the sleeve 6, and the push rod end of the hydraulic cylinder 12 is rotatably connected to the outer wall of the pressure tank 1.

[0027] In this embodiment, vibrations will be generated during the operation of the pressure tank 1. When the pressure tank 1 drops in height, the depth of the piston rod 7 inserted into the sleeve 6 increases, the spring is compressed and potential energy is accumulated, and at the same time, the air in the chute is quickly discharged along the exhaust pipe 10 and the intake pipe 11, and then the spring releases the potential energy and lifts the sleeve 6 and the pressure tank 1 to make them rise and reset. At this time, the outside air only enters the chute along the intake pipe 11. Due to the slow intake, the rise and reset of the pressure tank 1 is relatively slow, thereby absorbing the elastic potential energy and preventing the pressure tank 1 from rising and resetting quickly. When cleaning the inside of the pressure tank 1, the hydraulic cylinder 12 can be started, and the hydraulic cylinder 12 makes the pressure tank 1 pitch and swing, and when discharging the detergent, it can accelerate the discharge of detergent and sewage.

[0030] In this embodiment, each pin 5 is passed through the through hole of the flange 401 along the side of the end cover 4 away from the pressure tank 1 and through the socket 301 on the corresponding side of the slip ring 3, and then the slip ring 3 is rotated to make the annular groove 501 snap into the snap hole 302, and then the slip ring 3 is kept in the current state and does not move to prevent it from rotating with the ring 2, and then the ring 2 is rotated, and the ring 2 slides and pulls the slip ring 3, and then each pin 5 is tightened at the same time, so as to achieve the purpose of locking the end cover 4.
