Abstract

The utility model provides an air conditioning manifold pressure gauge, which comprises a high pressure gauge, a low pressure gauge, a high pressure pipe, a low pressure pipe respectively connected with the high and low pressure gauges and a valve is arranged thereon, and an intermediate pipe communicated with the high and low pressure pipes through a three-way pipe. The air conditioning manifoldpressure gauge is characterized in that the intermediate pipe is respectively connected with a vacuum pump, a refrigerator oil tank and a refrigerant tank through a manifold adapter. The vacuum pumping and pressure maintaining operations to the pipeline can be directly performed through the vacuum pump, then the refrigerator oil and the refrigerant are added directly, and the pipe connection is not required to be replaced frequently, so that simplifying the operation process greatly and the time and labor can be saved; and meanwhile the interfusion of the air is prevented efficiently, so as toensure the cooling effect; and the utility model has the advantages of simple structure, convenient operation, high operating efficiency, low labor intensity and the like.

Description

The air-conditioning manifold pressure gauge that simplifies the operation

Technical field

The utility model relates to a kind of tensimeter, and especially a kind of air-conditioning manifold pressure gauge is refrigeration plant maintenance and the specific purpose tool of safeguarding.

Background technology

Raising along with people's living standard, air-conditioning equipment not only enters into the room that people live and handle official business, also enter into the vehicles---the automobile of people's trip, on the train, incident maintenance simultaneously, the maintenance workload also strengthens thereupon, the air-conditioning manifold pressure gauge then is maintenance, safeguard the specific purpose tool of operation of air conditioning systems, it comprises gauge outfit, be connected the low-voltage tube of band valve on the gauge outfit its, intervalve and high-voltage tube, elder generation is with height during maintenance, the high-pressure outlet that low-voltage tube is corresponding with compressor of air conditioner respectively, after the low pressure suction inlet connects, by intervalve and vacuum pump, the refrigerating machine oil tank, alternately connecting of refrigerant tank, finish maintenance to operation of air conditioning systems, safeguard.Just because of in maintenance process, need frequent being connected of intervalve and vacuum pump, refrigerating machine oil tank, refrigerant tank of changing, not only operate loaded down with trivial details, time-consuming, require great effort and entrained air and influence refrigeration very easily, even cause problem such as line clogging.Therefore, be necessary prior art is improved.

Summary of the invention

For overcoming complicated operation that existing air-conditioning manifold pressure gauge exists, loaded down with trivial details, entrained air and reduce refrigeration causes deficiencies such as line clogging easily, and the utility model provides a kind of air-conditioning manifold pressure gauge that simplifies the operation.

The utility model is finished by following technical proposal: a kind of air-conditioning manifold pressure gauge that simplifies the operation, comprise the high and low pressure table, reach the intervalve that is communicated with high and low pressure pipe by three-way pipe with its high and low pressure pipe that goes up the band valve that the high and low pressure epiphase connects respectively, it is characterized in that intervalve passes through the multitube joint and links to each other with vacuum pump, refrigerating machine oil tank, refrigerant tank respectively, so that in maintenance, when safeguarding, directly carry out pipeline emptying, filling refrigerator oil, filling cold-producing medium by the multitube joint, need not alternately to change again.

Described multitube joint is a ducted body, ducted body is made as right cylinder or cuboid or round or the trigone or the polygonal body of band cavity, which is provided with a plurality of interfaces that are communicated with cavity, so that link to each other with intervalve, vacuum pump, refrigerating machine oil tank, refrigerant tank.

Interface on the described multitube joint is established four at least, wherein with on vacuum pump and the interface that the refrigerating machine oil tank links to each other valve is set, with handled easily and control.

Described multitube joint and intervalve are connected as a single entity, and perhaps link to each other with intervalve by pipe connecting piece, to be convenient for carrying and to operate.

The utility model compared with prior art has following advantage and effect: adopt such scheme, can be directly by the advanced line pipe of vacuum pump road vacuumize, pressurize, and then directly annotate refrigerator oil and cold-producing medium, need not frequently more replace tubes connection again, greatly simplified operating process, save time and laborsaving, simultaneously can also effectively prevent sneaking into of air, guarantee refrigeration, the utlity model has simple in structure, easy to operate, high efficiency, characteristics such as labour intensity is low are a desirable refrigeration plant maintenance in fact with safeguard specific purpose tool.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is another structure diagram of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As Fig. 1, the air-conditioning manifold pressure gauge that the utility model provides, comprise high pressure gauge 1, low-pressure meter 15, the high-voltage tube 4 of band T-valve 3 on its that links to each other with high pressure gauge 1, the low-voltage tube 12 of band T-valve 13 on its that links to each other with low-pressure meter 15, and by three-way pipe 2 and high-voltage tube 4, the intervalve 14 that low-voltage tube 12 is communicated with, wherein, high-voltage tube 4 links to each other with the refrigeration compressor high-pressure outlet by flexible pipe, low-voltage tube 12 links to each other with refrigeration compressor low pressure suction inlet by flexible pipe, intervalve 14 links to each other with multitube joint 11 by pipe connecting piece 17, multitube joint 11 is a ducted body, and this ducted body is made as the right cylinder of band cavity, also is provided with three other interfaces on the right cylinder, wherein interface 6 is provided with two-port valve 5, and link to each other with vacuum pump by flexible pipe, interface 7 jar links to each other by flexible pipe and cold-producing medium filling, and interface 9 is provided with two-port valve 10, and link to each other with refrigerator oil measuring cup 8 by suction pipe, 16 are hook.

As Fig. 2, remove intervalve 14 and directly link to each other with multitube joint 18, multitube joint 18 is a hollow circular tube, does not have hook simultaneously, all the other are all identical with Fig. 1.

During work, open two-port valve 5, make pipeline form vacuum, after pressurize does not have leakage, open valve 10 refrigerator oil in the measuring cup 8 is sucked in the refrigeration system, open T-valve 13 then the capacity cold-producing medium is filled in the refrigeration system through interface 7 by vacuum pump.
