That is, 21 is a valve body bent into an L shape, and an outflow port 22 is provided at one end of the valve main body 21, and an inflow port 23 is provided at the other end. Communicating flow path 2

6a is fixed to the peripheral edge of the outlet 22. Further, a valve seat 25 is provided in the middle of the flow path 24, and this valve seat 25 and the refrigerant pipe 16
A ball valve 26 and a stopper guide body 27 are disposed between the insertion end and the insertion end. As shown in FIGS. 4, 5, and 7, the stopper guide body 27 includes a circular stopper portion 28, and four holes protruding from the upper and lower portions and both sides of the outer circumferential portion of the stopper portion 28. The book guide section 29 is composed of a book guide section 29, and so on. A spherical surface portion 30 is formed on the stopper portion 28, and a portion of the ball valve 26 is fitted into this spherical surface portion 30. With this fitting, when the refrigerant gas flows in a predetermined direction, the ball valve 2
6 to prevent it from vibrating and producing abnormal noise. Further, a through hole 31 is bored in the approximate center of the spherical portion 30, and when the flow of refrigerant gas is stopped, the gas pressure of the refrigerant acts on the ball valve 26 from the refrigerant pipe 16 side through the through hole 31. I'm starting to do that.

As shown in the figure, the guide portion 29 is located at the center of the inner bottom of the valve body 21, and an inclined portion 32 is formed on the guide portion 29, along which the ball valve rolls.

着脱可能に接続されている。 On the other hand, the high pressure side valve device 18 is shown in FIG.
The same manual on-off valve as previously described is used, and one end of the refrigerant pipe 16 is connected to its inlet, and one end of the connection pipe 20 is removably connected to its outlet. ing.

続したのち高圧側弁装置１８の弁棒を動作させて
これを開放する。 Next, a method for installing the above-mentioned split type air conditioner will be explained. First, each indoor and outdoor unit 11, 13 is installed at a predetermined location, then one end of the connection pipe 19, 20 is connected to the valve 43, 44 of the indoor unit 11, and then the connection pipe 19, 20 is connected to the valve 43, 44 of the indoor unit 11. The other end is connected to the inlet 23 of the low pressure side valve device 17 of the outdoor unit 13, and the other end of the connecting pipe 20 is connected to the outlet of the high pressure side valve device 18 of the outdoor unit 13. After connecting in this way, the valve stem of the high pressure side valve device 18 is operated to open it.

まれる。 When the compressor 14 is operated, high-pressure refrigerant gas is discharged from the compressor 14 and sent to the outdoor heat exchanger 15, where it is heat-radiated and condensed. 20 to the capillary reach tube 41, where it is depressurized and then sent to the indoor heat exchanger 12. Then, after being evaporated and vaporized, it flows out into the connecting pipe 19 and is sucked into the compressor 14 via the low pressure side valve device 17.

てストツプする。しかして、冷媒ガスは弁本体２
１内の流通路２４に沿つて流れ、流出口２２から
冷媒管１６に流されることになる。 In the low-pressure side valve device 17, when refrigerant gas flows into the flow passage 24 of the valve body 21, the ball valve 26 is pressed by the flow pressure and rolls, separating from the valve seat 25 and moving into the flow passage 24. to open. At this time, the ball valve 26 rolls along the inclined part 32 of the guide part 29, comes into contact with the spherical part 30 of the stopper part 28, and is stopped. Therefore, the refrigerant gas is transferred to the valve body 2.
The refrigerant flows along the flow path 24 in the refrigerant pipe 16 from the outlet 22.

After this recovery, the low pressure side and high pressure side valve devices 17, 1
Remove one end of the connecting pipes 19, 20 from the valves 43, 44 of the indoor unit 11, respectively, and remove the other end from the valves 43, 44 of the indoor unit 11.
13 and move it.
この空気調和機の移設および出荷時において、

し冷媒の流出を防止する。 When relocating and shipping this air conditioner,
When the connecting pipe 19 is removed from the low pressure side valve device 17,
The refrigerant tries to flow out from the inlet 23, but
When the flow of the refrigerant gas is stopped, the refrigerant gas pressure is applied to the ball valve 26 from the refrigerant pipe 16 side through the through hole 31, and the ball valve 26 moves along the guide portion 29 of the stopper guide body 27 due to its own weight and the flow pressure of the refrigerant. Then, it rolls down and comes into contact with the valve seat 25 to close the flow passage 24 and prevent the refrigerant from flowing out.
このように、低圧側弁装置１７は球弁２６の転
動により開閉するため、空気調和機の据付、移
設、出荷時などに低圧側弁装置１７に接続配管１
９を着脱する際、その都度手動で弁棒を動作させ
て弁を開閉する必要がなく作業性が優れる。 In this way, the low pressure side valve device 17 is opened and closed by the rolling of the ball valve 26, so when installing, relocating, or shipping the air conditioner, the low pressure side valve device 17 is connected to the piping 1.
When attaching and detaching the valve 9, there is no need to manually operate the valve stem to open and close the valve each time, resulting in excellent workability.

を転動させ弁を開閉できる。 Further, the guide portions 29 of the guide stopper body 27 are provided protruding from the upper and lower portions and both sides of the stopper portion 28, and since there are four guide portions 29, the guide portions 29 are formed between the ball valve 26 and the guide portions 29, 29 on both sides. The clearance is small, preventing vibration of the ball valve 26 and ensuring that the ball valve 26
The valve can be opened and closed by rolling.

に示すようにａ，ｂ，ｃの三点で球弁２６が固定
され停止してしまう欠点がある。 By the way, considering the flow resistance of the refrigerant, it is preferable that the number of guide parts 29 be as small as possible, and it is better to have three guide parts (the ball valve 26 cannot be guided with two guide parts), but in the case of three guide parts, they are spaced at 120° intervals. , the clearance between the guide portion 29 and the ball valve 26 becomes large as shown in FIG. For this reason, the vibration of the ball valve 26 increases, making it impossible to guide the ball valve 26 well, and the guide stopper body 27 is eccentrically guided so that its center is located on the upper side in order to allow the ball valve 26 to roll. In order to process part 29,
The lengths of the two upper guide parts 29, 29 are shorter than the length of the lower guide part 29, and the ball valve 26 is fixed at three points a, b, and c as shown in FIG. It has the disadvantage of stopping.

傷つける不都合がある。 Note that there is a known valve device in which four protrusions are provided at a predetermined interval on the outer periphery of the valve body, and the refrigerant is caused to flow from the recesses formed between these protrusions. Since the valve device slides the protrusion of the valve body in contact with the circumferential surface of the valve body, frictional resistance is generated, and the operation is not as smooth as in the case of the present invention in which the ball valve 26 is rolled. The flow resistance of the refrigerant also increases, and furthermore, if the refrigerant contains impurities, there is a problem that the inner circumferential surface of the valve body may be damaged.

る。 As explained above, the present invention has a valve device installed on the high-pressure side of a refrigeration cycle in which a compressor, an outdoor heat exchanger, a pressure reducing device, and an indoor heat exchanger are sequentially connected. The valve device installed on the low pressure side is provided with a ball valve and a stopper guide body in the valve body, and when fluid flows, the ball valve is separated from the valve seat by the flow pressure to open the flow path. When the flow of fluid is stopped, the ball valve is moved by its own weight along the guide portion of the guide stopper body to come into contact with the valve seat and close the flow path. When attaching or detaching the connecting piping to the valve body, the valve can be opened and closed automatically without having to attach or detach the cap each time and manually operate the valve stem, which is extremely easy to do. . Furthermore, since a cap, bush, O-ring, etc. are not required, the structure can be simplified and costs can be reduced.

う効果を奏するものである。 In addition, guide parts are provided protruding from the upper and lower parts and both sides of the stopper part, and the lateral movement of the ball valve toward the stopper part is restricted by the guide parts on both sides. The clearance formed between the ball valve and the ball valve becomes small, thereby preventing the ball valve from vibrating, and providing the effect that the ball valve can be reliably rolled to open and close the valve.
