I think few people can easily buy a regulator.
In Japan, it is sold in monotarou, but the price is quite high.
Considering the running cost of carbonated water, even though it is known that you can get the original even if you buy a high-priced regulator, the initial cost is 10,000 yen but there is resistance.
Many people used to get used at auction sites etc., but since I was able to buy new and cheap ones, I will record here with the knowledge.
I bought it from eBay for 3000 yen.
I was worried because I was buying from overseas, but I thought it would be fine if it was around 3000 yen and purchased.
However, I was written on the sales page as “BEER BREWING CARBON DIOXIDE REGULATOR“, and I thought that it was for making carbonate because the photo was also a beer, so I was not so worried.
Originally I used high pressure gas often at work and I also had the qualification
There is a knowledge such as gas cylinder and pressure display, and there is a background that the connection was made by myself and the device was also made well.
The goods arrived about 10 days from the order. It’s a standard number of days for buying from eBay.
The delivery box was delivered wrapped in black vinyl.
I was surprised to open it. YAMATO? JAPAN? Is it made in Japan?
But, Made in China.
Well, that’s right. That amount of money.
Packing like this.
It is not good to be angry at a hole.
Checkpoint is pressure that can be displayed.
The pressure on the primary side needs to be 15MPa referring to the fact that the 47L cylinder, which is about 150cm, contains 13.5MPa.
Since carbonated water is made this time, it is necessary to be able to adjust the secondary side to 0.3 to 0.4 MPa.
Since the mouth of carbon dioxide gas cylinders available in Japan is pitch 14 with a diameter of 22 mm, it must be a W22-14 connection port. By the way, if it is CGA320 if it is overseas, it will not be able to connect to the carbon dioxide gas cylinder purchased in Japan.
W22-14 is OK with W21.8-14. The diameter is only 0.2 mm but it can be connected.
And W21.8-14 is the same as DIN 477.
In other words, if you select W22-14, W21.8-14 or DIN 477, it is OK.
This time, I wanted to do it cheaply, but I’m not really good but I’m connected with a hose band.
The diameter is about 7 to 8 mm
For safety reasons, it is better to choose a Swagelok or PISCO fitting.
It’s about 13 mm in diameter, so it’s G 1/4 or PT 1/4 inch? Although it is necessary to remove and check the parallel screw for pipe or the taper screw for pipe.
Connection to a carbon dioxide gas cylinder requires a monkey wrench which opens 30 mm. It was a large pliers in the video, but I borrowed a monkey wrench that opens 30 mm later and tightened.
When opening the regulator valve, turn it opposite to the faucet. In other words, turn clockwise to increase the secondary pressure.
↑ Clockwise is + mark (open), right? The left valve is open counterclockwise.
