Claims

[Scope of Claim for Utility Model Registration] (1) A refrigerant inlet passage that is airtightly fixed to the top of the liquid tank, connects to the condenser on one side of the horizontal axis and communicates with the inside of the liquid tank, and expands on the other side of the horizontal axis. In a T-type joint formed with a refrigerant outlet passage connected to a valve and connected to and communicated with a refrigerant extraction pipe provided in a liquid tank, the T-type joint has a flat portion at the top of a vertical shaft, and the refrigerant outlet The passage is formed by drilling a vertical passage penetrating from the lower surface of the vertical axis to the flat part of the top, and drilling a horizontal passage perpendicularly communicating from the outlet opening to the middle of the vertical passage on the horizontal axis, and forming the passage through the vertical passage. Insert a bushing into the top opening and place the sight glass, install an O-ring in the space surrounded by the flange extension of the bushing and the outer periphery of the sight glass, and attach the presser metal fitting to the sight glass to remove the presser foot. T in a liquid tank for a refrigerator constructed by airtightly fixing a metal fitting to a flat surface
Structure of gas confirmation window of type joint. (2) Airtightly installed at the top of the liquid tank,
A T-type joint having a refrigerant inlet passage and a refrigerant outlet passage is provided with a flat part at the top of the vertical axis, and the refrigerant outlet passage has a vertical passage penetrating from the lower surface of the vertical axis to the flat part of the top, and an outlet opening on the horizontal axis. a horizontal passage communicating orthogonally to the middle of the vertical passage; a bushing is inserted into the upper opening of the vertical passage to place a sight glass; In the gas confirmation window of a T-type joint formed by providing an O-ring in the space surrounded by the space, attaching a holding fitting to the sight glass via packing, and fixing the holding fitting to the flat part airtightly, the bushing is The cylinder shaft portion is formed with a flange on the outer periphery of the upper opening edge, and the sight glass is formed to have a larger diameter than the outer periphery of the flange of the bushing, and is inserted into the upper opening of the vertical passage forming the refrigerant outlet passage. Claim 1 of the Utility Model Registration Claim: When the sight glass is placed on the bush, the area surrounded by the outer periphery of the flange of the bush and the outer periphery of the sight glass has a space for installing an O-ring. The structure of the gas confirmation window of the T-type joint in a liquid tank for a refrigerator. (3) Airtightly installed at the top of the liquid tank,
A T-type joint having a refrigerant inlet passage and a refrigerant outlet passage is provided with a flat part at the top of the vertical axis, and the refrigerant outlet passage has a vertical passage penetrating from the lower surface of the vertical axis to the flat part of the top, and an outlet opening on the horizontal axis. a horizontal passage communicating orthogonally to the middle of the vertical passage; a bushing is inserted into the upper opening of the vertical passage to place a sight glass; In the gas confirmation window of the T-shaped joint, which is formed by providing an O-ring in the space surrounded by the sight glass, attaching a holding metal fitting to the sight glass, and sealingly fixing the holding fitting to the flat surface, the holding metal fitting caps the sight glass. The cylindrical part has a peephole surrounded by an inner peripheral flange on the upper surface thereof, and an outer peripheral flange at the lower edge. A structure of a gas confirmation window of a T-shaped joint in a liquid tank for a refrigerator as claimed in claim 1, which is configured to be hermetically fixed to the flat part of the top of the vertical shaft.
