Embodiment 1
Referring to Fig. 1 and Fig. 2, the present invention is improved to four-way check valve with existing three-way cut-off valve, the four-way check valve concrete structure is, described four-way check valve comprises the sliding valve core 5 in valve body 6 and the valve body 6, has needle-valve service ports 1 on the valve body 6, connect the adapter 2 and the adapter 3 that is connected indoor set of cross valve, needle-valve 1-1 is housed in the needle-valve service ports 1, but in order to realize freezing and to heat under the state all purposes of fluoridize, also be provided with the adapter 4 that connects the compressor air suction mouth on the valve body 6, this adapter 4 that connects the compressor air suction mouth connects the compressor air suction mouth, when sliding valve core 5 is open mode, the passage 1-2 of needle-valve service ports 1 is communicated with the adapter 4 that is connected the compressor air suction mouth, and the adapter 2 that connects cross valve also is communicated with the adapter 3 that is connected indoor set.Because compressor air suction mouth pressure when heating and freeze is all very low, thus can heat with refrigerating state under all can realize fluoridize.
Referring to Fig. 3, mating surface with sliding valve core 5 in the valve body 6 has internal thread, two sections external screw thread 5-1 are arranged on the sliding valve core 5, be cylindrical section 5-2 between two sections external screw thread 5-1, cylindrical section 5-2 is necking down light face, be that the diameter of cylindrical section 5-2 is less than the diameter at external screw thread 5-1 place, form the space between the inner face of cylindrical section 5-2 and valve body 6 like this, when sliding valve core 5 is open mode, the passage 1-2 of needle-valve service ports 1 and the adapter 4 that connects the compressor air suction mouth are connected with space between valve body 6 inner faces by cylindrical section 5-2, thereby can carry out fluoridize by needle-valve service ports 1 place.Two sections external screw thread 5-1, one section bottom that is located at sliding valve core 5, another section is located at the middle and upper part of sliding valve core 5.Have o-ring groove 5-3 on the top of sliding valve core 5, rubber seal 5-4 is contained in the sealing circle groove 5-3, to play the integral sealing effect.
The arrangement of four-way check valve is, the adapter 3 that connects adapter 4, the needle-valve service ports 1 of compressor air suction mouth and is connected indoor set from the top down position on valve body 6 is successively: the adapter 3 that the adapter 4 that connects the compressor air suction mouth is 1 placed in the middle in upper, needle-valve service ports, connect indoor set is down, and the adapter 2 of connection cross valve is located at valve body 6 bottoms.By the setting of above-mentioned position relationship, in the time of can making sliding valve core 5 be in open mode, the adapter 2 that connects cross valve is communicated with the adapter 3 that is connected indoor set, and needle-valve service ports 1 is communicated with the adapter 4 that is connected the compressor air suction mouth.Referring to Fig. 2.
Sliding valve core 5 rotates mobile upper-lower position by interior hex tool, all there is one section external screw thread 5-1 that sealing function is arranged sliding valve core 5 bottoms and middle and upper part, be cylinder light face section in the middle of the two external screw thread 5-1, top has a rubber seal 5-4 to play the effect of integral sealing.
Referring to Fig. 1, when sliding valve core 5 is in the four-way check valve bottom, it is closure state, this moment, needle-valve service ports 1 can be communicated with the adapter 3 that connects indoor set by the cylindrical section in the middle of the sliding valve core 5, when air-conditioning is installed, vacuumize with the adapter 3 that is connected indoor set by needle-valve service ports 1, indoor set and the air that connects in the machine pipeline are extracted out.At this moment, connect the adapter 2 of cross valve and the adapter 4 that is connected the compressor air suction mouth other interface connection of also getting along well that do not communicate.
Referring to Fig. 2, when vacuumize complete after, hex tool rotates sliding valve core 5 in using, make it be in the top of four-way check valve, be open mode this moment, and cold-producing medium enters the adapter 3 that connects indoor set from the adapter 2 that connects cross valve, realizes the circulation of the cold-producing medium of indoor and outdoor air-conditioning system.The passage 1-2 of needle-valve service ports 1 is communicated with the adapter that is connected the compressor air suction mouth 4.
Referring to Fig. 4 and Fig. 5, four-way check valve S is configured in the air-conditioning duplex matter system, connect the adapter 2 of cross valve and the pipeline connection of cross valve 10, connect the adapter 3 of indoor set and the pipeline connection of evaporimeter 7 ends, connect the adapter 4 of compressor air suction mouth and the pipeline connection of compressor 8 suction ends.
When lack of fluorine of air-conditioners, connect the compressor air suction mouth owing to connecting the adapter 4 of compressor air suction mouth, pressure is very low, needle-valve service ports 1 is communicated with the adapter 4 that is connected the compressor air suction mouth, therefore can directly carry out fluoridize from needle-valve service ports 1, fluorine from the space between the cylindrical section 5-2 of needle-valve service ports 1 → passage 1-2 → sliding valve core 5 and the valve body 6 → be connected adapter 4 → air-conditioning refrigerant circulatory system of compressor air suction mouth.Because needle-valve service ports 1 is communicated with all the time with the adapter 4 that is connected the compressor air suction mouth, refrigerant pressure is low, can according to complete machine power, air outlet temperature, relatively accurately judge and answer fluorine adding content.If at the fluoridize in winter, do not need by forced refrigeration or pull out the cross valve wiring and carry out the refrigerating operaton fluoridize, can directly when heating the state operation, pass through needle-valve service ports 1 fluoridize, heat stable operation this moment, leaving air temp is true and reliable, can according to complete machine power, air outlet temperature, relatively accurately judge and answer fluorine adding content, improve fluoridize efficient, reduced the probability of false judgment fluorine amount.
As seen, adopt this four-way check valve S to improve fluoridize efficient, reduced the probability of false judgment fluorine amount.
A kind of fluoridize device of air-conditioner, described fluoridize device comprises the needle-valve service ports, in the described needle-valve service ports needle-valve is housed, the other end of described needle-valve service ports is connected with the pipeline of compressor of air conditioner air entry, makes the passage of needle-valve service ports and the pipeline connection of compressor of air conditioner air entry.This embodiment can open needle-valve from needle-valve service ports end and carry out fluoridize, in the pipeline of the other end of the passage of fluorine → needle-valve service ports → needle-valve service ports → needle-valve service ports → compressor air suction mouth → air-conditioning refrigerant circulatory system.
A kind of fluoridize device of air-conditioner, described fluoridize device comprises the two-way stop valve, and an end of described two-way stop valve is the fluoridize mouth, and the other end is connected with the pipeline of compressor of air conditioner air entry.During fluoridize, the pipeline of fluoridize tank is connected with the fluoridize mouth, open the sliding valve core of two-way stop valve, but fluoridize just, in the fluoridize mouth of fluorine → two-way stop valve → two-way stop valve → pipeline of the other end of two-way stop valve → compressor air suction mouth → air-conditioning refrigerant circulatory system in.
