Description

Refrigerator easy to add refrigerant

Technical Field

The utility model relates to a refrigerator equipment field, concretely relates to easily add refrigerator of refrigerant.

Background

Screw chillers are the core of refrigeration systems for compression refrigeration.

The screw refrigerator adopts R22 refrigerant for refrigeration, and after the screw refrigerator operates for a period of time, the refrigerant is lost, at the moment, the screw refrigerator needs to be isolated from the system after being stopped, and the single machine operates to supplement the refrigerant.

The screw refrigerator needs to be stopped continuously to add the refrigerant, so that the industrial manufacturing efficiency is reduced, and a series of other equipment which runs by the screw refrigerator easily breaks down due to the stop of an industrial manufacturing production line.

Disclosure of Invention

In order to overcome not enough among the prior art, the utility model provides an easily add refrigerator of refrigerant, it has the refrigerant and easily adds, and the screw rod refrigerator need not the benefit of parking.

In order to realize the above purpose, the utility model discloses an easily add refrigerator of refrigerant, including the refrigerant induction port, the refrigerator still includes that the refrigerant adds pipe, stop valve, interface structure, refrigerant hose, manometer, refrigerant jar, and the refrigerant adds pipe and refrigerant induction port intercommunication, and the stop valve setting adds on the pipe at the refrigerant, and the refrigerant hose adds the union coupling through interface and refrigerant, and the manometer setting is between refrigerant hose and refrigerant jar for detect the pressure of refrigerant in the refrigerant hose.

Further, the interface structure includes connects ring, interface groove, thread bush, connects ring and interface groove looks adaptation, and the interface groove sets up on the refrigerant adds the pipe, and thread bush and connect the ring conflict and threaded connection add the outside of pipe at the refrigerant.

Furthermore, a sealing ring is embedded at the end part of the connecting ring.

Furthermore, a rotation limiting piece is arranged on the connecting ring, and a rotation limiting groove matched with the rotation limiting piece is formed in the refrigerant adding pipe.

Furthermore, a first conical surface is further arranged on the connecting ring, and a second conical surface attached to the first conical surface is arranged on the interface groove.

Has the advantages that: the refrigerant adding pipe is arranged, so that the refrigerant can be directly added to the refrigerant air suction port through the refrigerant adding pipe, the refrigerator is not required to be stopped, the use is convenient, and the industrial manufacturing smoothness is high.

Detailed Description

The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1, the first-choice embodiment of the present invention is a refrigerator that can add refrigerant easily, and includes a refrigerant suction port 1, a refrigerant adding pipe 2, a stop valve 3, an interface structure, a refrigerant hose 4, a pressure gauge 5, and a refrigerant tank 6.

The refrigerant suction port 1 is a refrigerant inlet of the refrigerator, the refrigerant adding pipe 2 is arranged on the refrigerant suction port 1 and communicated with the refrigerant suction port 1, and the refrigerant adding pipe 2 is used for adding refrigerants to the refrigerant suction port 1 under the condition that the refrigerator does not stop.

The stop valve 3 is arranged on the refrigerant adding pipe 2 and used for opening and closing the refrigerant adding pipe 2. The refrigerant hose 4 is connected to the refrigerant adding pipe 2 through an interface, and is sealed with the refrigerant adding pipe 2.

The refrigerant tank 6 is connected with the refrigerant hose 4, and the pressure gauge 5 is arranged on the refrigerant hose 4 and used for detecting the pressure of the refrigerant in the refrigerant hose 4 when the refrigerant is added to the refrigerant suction port 1.

When the refrigerator needs to increase the refrigerant, only the stop valve 3 needs to be opened, and then the valve on the refrigerant tank 6 is slightly opened, because the pressure in the refrigerant tank 6 is greater than the pressure at the refrigerant air inlet, the refrigerant can enter the refrigerant air inlet, and the pressure gauge 5 displays the refrigerant pressure in the refrigerant hose 4 at any time.

As shown in fig. 2, the interface structure includes a connection ring 7, an interface groove 8, and a thread bushing 9, the refrigerant hose 4 is connected to the connection ring 7, the connection ring 7 is hollow and used for circulating the refrigerant, the thread bushing 9 is sleeved on an end portion of the refrigerant hose 4 and is integrally located on an outer side of the connection ring 7, and the connection ring 7 is adapted to the interface groove 8 in shape. After the connecting ring 7 is inserted into the interface slot 8, the threaded sleeve 9 is in threaded connection with the outer side of the refrigerant adding pipe 2.

The outer wall of the connecting ring 7 is provided with a rotation limiting piece 10, and the position of the refrigerant adding pipe 2, which is positioned at the interface groove 8, is also provided with a rotation limiting groove 11 matched with the rotation limiting piece 10. After the rotation limiting piece 10 is inserted into the rotation limiting groove 11, the connecting ring 7 cannot rotate relative to the axis of the connecting groove 8.

Moreover, the outer surface of the adapter ring 7 is provided with a first conical surface 12, the interface groove 8 is also provided with a second conical surface, and the surface of the first conical surface 12 is tightly propped against the second conical surface, so that the connection firmness of the adapter ring 7 and the refrigerant adding pipe 2 can be ensured.

A sealing ring 14 is embedded at the end part of the connecting ring 7, and two opposite surfaces of the sealing ring 14 are respectively and tightly propped against the refrigerant adding pipe 2 and the connecting ring 7.

The above detailed description merely describes the preferred embodiments of the present invention and does not limit the scope of the present invention. Without departing from the design concept and spirit scope of the present invention, the ordinary skilled in the art should belong to the protection scope of the present invention according to the present invention provides the text description and drawings to the various modifications, replacements and improvements made by the technical solution of the present invention. The scope of protection of the present invention is determined by the claims.
