Claims

[Scope of utility model registration request]

(1) A removable leak test joint is airtightly attached to the open end of the heat medium piping provided in the heat exchanger, and the probe gas is sealed into the heat medium pipe and recovered through the leak test joint. A joint for a leak test of a heat exchanger is configured to perform a leak test; a holding device is inserted into the pipe from the open end of the heat medium piping and holds the entire joint; an elastic seal body that tightly adheres to the outer circumferential surface of the heat medium pipe to prevent gas leakage from inside the heat medium pipe and the joint; and an elastic seal body that tightly adheres to the outer circumferential face of the heat medium pipe. A joint for leak testing of a heat exchanger, characterized by comprising a pressing device for pressing.

(2) The holding device includes a pressing force transmission pipe arranged to receive pressing force from the pressing device, and is wedge-operated in response to the pressing force from the pressing force transmission pipe, and is pressed against the inner surface of the heat medium pipe. 2. A joint for leak testing of a heat exchanger according to claim 1, which comprises a retaining ring which is arranged to generate a retaining force.

(3) The pressing device includes a contact ring that comes into contact with and presses the elastic seal body and the pressing force transmission tube, and a pressing lever that has an operating end that presses and releases the contact ring. A joint for leak testing of a heat exchanger according to claim 2 of the registered utility model.
