Abstract
The utility model discloses an evaporator assembly pressure-maintaining gas-filling/leakage-detecting device for an air conditioner, which comprises an evaporator main body (1). The device is characterized in that one end of the evaporator main body (1) is an inlet end (2), and the other end of the evaporator main body (1) is an outlet end; both the inlet end (2) and the outlet end are provided with connecting pipe joints(3); a gas-filing process nut (4) is sheathed on the connecting pipe joint (3) at the inlet end (2); an inner hole of the gas-filling process nut (4) is internally provided with a sealing plug (5); a nut is sheathed on the connecting pipe joint at the outlet end; and a sealing pad is sheathed on the nut. According to the device, not only an external injection needle can be conveniently inserted into, but also perfect sealing state can be kept after the injection needle is pulled out of.
Description
Technical field
The utility model relates to a kind of evaporator using for air assembly pressurize inflation/leakage detection apparatus.
Background technique
Present evaporator using for air need charge into gas (as nitrogen) in this system when hunting leak or keep system's barotropic state, perhaps cut-in pressure table detection system internal pressure, but do not have interface and seal arrangement at entrance point, source of the gas can't directly charge into like this, uses very inconvenient.
Summary of the invention
The utility model provides a kind of evaporator using for air assembly pressurize inflation/leakage detection apparatus, and it not only can make outside entry needle insert easily, and the sealing state that remains intact after entry needle is extracted.
The utility model has adopted following technological scheme: a kind of evaporator using for air assembly pressurize inflation/leakage detection apparatus, it comprises vaporizer body, one end of described vaporizer body is an entrance point, the other end is an outlet end, on entrance point and outlet end, all be provided with Tube to tube fittings, on the Tube to tube fittings of entrance point, be with the gas filling technology nut, in the endoporus of gas filling technology nut, be provided with sealing plug, on the Tube to tube fittings of outlet end, be with nut, be with sealing gasket on the nut.
Described gas filling technology nut is an ABS plastic.The surface that described sealing plug contacts with Tube to tube fittings is provided with 45 ° chamfering groove, and the chamfering groove is covered with the mouth of pipe of Tube to tube fittings.Described sealing plug is a nitrile butadiene rubber.
The utlity model has following beneficial effect: the utility model not only can make outside entry needle insert easily, and the sealing state that after entry needle is extracted, remains intact, entry needle can be connected with source of the gas in addition, can in sealing system, charge into gas like this, entry needle can be connected with pressure gauge, can detect the force value of gas in the sealing system like this.
