Disclosed is a low-expansion borosilicate transparent glaze, a preparation method thereof, and use thereof in preparation of a glaze product by secondary fusion-cast molding. The low-expansion borosilicate transparent glaze has raw material composition by mass percentage including: 72%-80% of SiO, 4%-12% of BO, 4%-12% of NaO, 0.1%-4% of CaO, 0.1%-6% of AlO, 0-0.05% of FeO, 0-2% of MgO, 0-2% of KO, 0-2% of ZnO, 0-2% of BaO, 0-2% of ZrO, 0-0.5% of LiO, and 0-0.5% of TiO, wherein a sum of mass percentages of SiO, BOand AlOis 85%-95%. The preparation method includes steps of: (1) after mixing dried raw materials, melting at 1400-1540° C. to obtain a high-temperature glass melt; (2) cooling the high-temperature glass melt to 1150-1230° C. to mold; and (3) annealing a molded glass at 530-600° C. to obtain the low-expansion borosilicate transparent glaze.

A pipeline connection device includes a first connecting member, a second connecting member and a sealing member. The first connecting member includes a first channel and an abutting portion. The second connecting member includes a second channel and a first groove portion. The first groove portion includes a first side wall and a first receiving groove to receive the sealing member. At least part of the abutting portion is received in the first receiving groove and abuts against the sealing element. A first gap not greater than 0.3 mm is provided between the abutting portion and the first side wall; or the first connecting member and the second connecting member include at most two annular friction surfaces. As a result, mutual jamming of the first connecting member and the second connecting member can be avoided. Besides, a pipeline adapting assembly having the pipeline connection device is disclosed.

A gas-liquid separator includes a first cylinder, a second cylinder and a heat exchange assembly. The first cylinder is surrounded by the second cylinder at a predetermined distance. The heat exchange assembly is arranged between the first cylinder and the second cylinder. The heat exchange assembly includes a collecting pipe. An extension direction of the collecting pipe is parallel to an axial direction of the first cylinder. At least a part of a side wall surface of the first cylinder is formed with an avoidance portion recessed inwardly. At least a part of the collecting pipe is arranged between the avoidance portion and the second cylinder.

Gas-liquid separator and air conditioning system

A gas-liquid separator includes a first cylinder, a second cylinder, a heat exchange pipe, a flow guide pipe, a distribution portion, and a lower sealing cover. The gas-liquid separator has a first cavity and a second cavity. The second cavity includes at least the space located in the first cylinder. The distribution portion includes a first passage. One end of the first passage is communicated with that of the flow guide pipe. The other end of the flow guide pipe is communicated with the second cavity. The other end of the first passage is communicated with the first cavity. The lower sealing cover is located at the other side far away from the distribution portion. The gas-liquid separator further includes a flow passage located, at least in part, in the lower sealing cover, communicated with the first cavity and communicated with the second cavity.

Gas-liquid separator and heat exchange system

The present application provides a pipeline adapter including a first connection block, a second connection block, a fastener and a seal ring. The first connection block is provided with a first channel and a first annular positioning groove disposed around the first channel. The second connection block is provided with a second channel communicating with the first channel and a second annular positioning platform fitting inside the first annular positioning groove. The second annular positioning platform is disposed around the second channel. The fastener connects the first connection block to the second connection block. The seal ring fits between the first annular positioning groove and the second annular positioning platform. The pipeline adapter is convenient to use, has a favorable sealing effect, and facilitates pipeline connection of a refrigeration system.
