Detailed Description

The utility model is further described below in connection with the examples, which are not to be construed as limiting the utility model in any way, but rather as falling within the scope of the claims.

Referring to fig. 1-2, the connecting pipe for the refrigeration equipment comprises a main pipe section 1, a safety pipe section 2, a purifying pipe section 3 and a main pipe section two 4 which are connected in sequence. In this embodiment, the main pipe section 1, the safety pipe section 2, the purge pipe section 3, and the main pipe section two 4 are collectively referred to as pipe sections. The purifier 6 is arranged in the purifying pipe section 3, the pressure gauge 5 is arranged on the safety pipe section 2, and the buffer tank 9 communicated with the safety pipe section 2 is arranged below the safety pipe section 2. The following are some functional structures on the connecting pipe for the refrigeration equipment in the prior art, and the utility model does not improve the functional structures.

Compared with the prior art, the utility model is improved in that one end of the buffer tank 9 is provided with the discharge pipe 10 communicated with the buffer tank, one end of the discharge pipe 10 far away from the buffer tank 9 is communicated with the purifying pipe section 3, and one end of the discharge pipe 10 communicated with the purifying pipe section 3 is positioned on the purifying pipe section 3 between the purifier 6 and the main pipe section two 4. A control valve 11 is installed in the discharge pipe 10.

By such an arrangement, when the purifier 6 is blocked, the cold air in the safety pipe section 2 can enter the buffer box 9 through the connecting pipe and enter the pipe section at the rear end of the purifier 6 through the discharge pipe 10, thereby bypassing the blocked purifier 6, realizing normal air supply for the subsequent pipe section and facilities, and ensuring normal air supply for the facilities.

Preferably, a safety valve 8 is mounted on the connecting pipe between the buffer tank 9 and the safety pipe section 2. The safety valve 8 and the control valve 11 are operated simultaneously to realize continuous cold air delivery.

For the connection pipe of the cold air, copper pipes are generally adopted. Moreover, since the delivery pressure of the cold air is generally not large, the wall thickness of the copper tube used is generally between 0.5 and 1 mm. In the prior art, the connection between pipe sections is realized by adopting a welding flange connection mode. However, the copper pipe has a small wall thickness, so that the welding requirement is high, the welding difficulty is high, and the perforation phenomenon caused by overselding is easy to occur. To solve these problems, the first main pipe section 1 and the safety pipe section 2 and the purge pipe section 3 and the second main pipe section 4 of the present utility model are connected by an i-seal joint 7.

Specifically, the I-seal joint 7 includes an I-section 71, an outer enclosure 72, and a clip 73. The i-shaped member 71 has a recess therein for receiving the end of the pipe section, the recess matching the end of the pipe section received therein. A sealing cushion 74 is inserted into the groove. The outer enclosure 72 wraps the outer periphery of the i-shaped member 71, and positioning portions 76 contacting with the outer wall of the pipe section are disposed at two ends of the outer enclosure 72. The clip 73 is mounted on the positioning portion 76.

In use, the ends of the tube segments are inserted into the grooves of the I-members 71 and the end surfaces of the tube segments are compressed against the sealing cushion 74 to enhance the sealing effect. The outer enclosure 72 is then placed over the i-section 71. The outer surrounding member 72 is provided with a slit aligned with the axial direction thereof. When it is mounted on the I-shaped member 71, the notch is directly spread to cover the I-shaped member 71. Finally, the outer surrounding piece 72 is locked on the pipe section through the clamp 73, so that the I-shaped piece 71 and the pipe sections at the two ends of the I-shaped piece 71 can be locked and positioned.

Preferably, a friction pad 75 is fixed below the positioning portion 76 to prevent the pipe section from moving outwards, thereby improving the reliability of pipe section installation.

While only the preferred embodiments of the present utility model have been described above, it should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present utility model, and these do not affect the effect of the implementation of the present utility model and the utility of the patent.
