Problems solved by technology

[0002] In the existing charging and recovery devices, in order to recover the refrigerant into the liquid storage tank, it is generally realized by using a single-layer modular valve block to control the solenoid valve, that is, the solenoid valve connects the channel and the liquid storage tank respectively. tank; in the recovery process, in order to reduce the pressure and protect the compressor, it is necessary to connect the channel to balance the pressure, that is, to perform heat exchange to cool the balance; in the recovery process of the device, in order to obtain clean gas, an additional dry filter device is required ; The oil separated during recovery needs to be discharged into the oil drain bottle; in addition, in order to ensure the safety of the entire channel, it is often necessary to connect various pressure sensors in the channel; in the existing charging or recovery device, In order to control each channel, that is, to control the connection and disconnection of the channel, a solenoid valve is often installed in the channel for control, which results in more solenoid valve control and increases the complexity of the channel.
Therefore, the existing single-layer modular valve block installation structure has complicated internal passages, consumes a large space for installation, and takes a long time for detection and installation, which is not conducive to the improvement of productivity

Abstract

The invention provides a fluid filling and recovery device. The device comprises a first module; a second module and a connecting pipe; the first module comprises a first channel block, wherein the channel block is provided with a first fluid channel and a fluid connector connected with the fluid filling and recovery device, the first channel block is provided with a filling control valve and a recovery control valve, and the first fluid channel is communicated with the fluid connector and the filling control valve and is communicated with the fluid connector and the recovery control valve; the second module comprises a second channel block provided with a second fluid channel, the second channel block is provided with a connector used for installing a fluid ingredient separating device and is communicated with a connector used for installing the fluid ingredient separating device; the connecting pipe is externally provided with a first channel block and a second channel block and is communicated with the fluid channel and the second fluid channel through fluid. According to the fluid filling and recovery device provided by the invention, the arrangement of the channels can be simplified when all functions can be realized, and the space needed by the channels can be saved; furthermore, the fluid filling and recovery device is likely to be dismounted and detected.

Description

technical field [0001] The invention relates to a fluid filling and recovery device, in particular to a fluid filling and recovery device with double modules for multi-channel flow control of a control valve. Background technique [0002] In the existing charging and recovery devices, in order to recover the refrigerant into the liquid storage tank, it is generally realized by using a single-layer modular valve block to control the solenoid valve, that is, the solenoid valve connects the channel and the liquid storage tank respectively. tank; in the recovery process, in order to reduce the pressure and protect the compressor, it is necessary to connect the channel to balance the pressure, that is, to perform heat exchange to cool the balance; in the recovery process of the device, in order to obtain clean gas, an additional dry filter device is required ; The oil separated during recovery needs to be discharged into the oil drain bottle; in addition, in order to ensure the s...
