With the continuous expansion of the market of Lianggong valve in Shanghai, many illegal businessmen pretend to transform the valve in order to obtain huge profits, which brings very unnecessary danger to the installation project. Therefore, it is necessary to introduce the identification method of regeneration valve. What are the main valve camouflage means in valve market stores now?

造假的手段有以下幾種：

The means of counterfeiting are as follows:

1.用鐵、碳鋼制造閥門，修復廢品閥門，填充如下。

1. Make valves with iron and carbon steel, repair waste valves and fill them as follows.

2、地方小廠的閥門產品包括大廠家的注冊商標，是虛假的。

2. The valve products of small local factories, including the registered trademarks of large brand manufacturers, are false.

3、假冒大工廠的用戶、經銷商、代理店，系著羊頭賣狗肉。

3. Fake large factory users, dealers and agency stores sell dog meat with sheep's head.

4、做鋼印，把普通級閥門打成d級閥門，貪圖暴利。

4. Make a steel seal and turn the ordinary valve into a D-class valve for profiteering.

上海良工閥門整修的危害很大，不僅擾亂市場秩序，還給施工質量帶來潛在危險，對社會危害很大。我們只知道偽裝的手段還不夠，就要識別更生閥。其次，我來告訴你識別更生閥的方法。

Shanghai Lianggong valve renovation is very harmful, which not only disturbs the market order, but also brings potential hazards to the construction quality and does great harm to the society. We only know that camouflage is not enough, we need to identify the regeneration valve. Secondly, let me tell you how to identify the regeneration valve.

1、顏色，更生閥在顏色方面與正規有很大不同。這些廉價材料外觀發白，與閥門鋼的偏綠明顯不同。

1. Color, regeneration valve is very different from regular brands in color. The appearance of these cheap materials is white, which is obviously different from the green of valve steel.

2、從鋼印來看，純正閥的鋼印在閥門不過熱之前，是用鋼印技術壓制的，所以字體很清晰。更生閥的字體不均勻，模糊不清。

2. From the perspective of steel seal, the steel seal of pure valve is pressed with steel seal technology before the valve is not overheated, so the font is very clear. The font of the regeneration valve is uneven and blurred.

3、看油跡，為了偽造翻新后的閥門達到防銹目的，如果在閥門表面涂上厚厚的油污，會降低閥門本身的粗糙度。

3. Look at the oil stains. In order to forge the refurbished valve and achieve the purpose of rust prevention, if thick oil is coated on the valve surface, the roughness of the valve itself will be reduced.

4、尺寸等于或太小于DN80的閥關不上。

4. The valve with size equal to or too smaller than DN80 cannot be closed.

5、一看閘板，更生閥的閘板一般有磨光的痕跡和銹跡。

5. A look at the ram, the ram of the regeneration valve generally has polishing marks and rust.

6、拆下桿的上端螺母和標志，看看里面的鎖緊螺母的材質，正規的材質是真的?如果不是的話就是假的。

6. Remove the upper nut and mark of the rod and see the material of the lock nut inside. Is the material of regular brand true? If not, it's fake.
