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?

造假的手段有以下几种：

The means of counterfeiting are as follows:

1.用铁、碳钢制造阀门，修复废品阀门，填充如下。

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

2、地方小厂的阀门产品包括大厂家的注册商标，是虚假的。

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

3、假冒大工厂的用户、经销商、代理店，系着羊头卖肉。

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

4、做钢印，把普通级阀门打成d级阀门，贪图暴利。

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

上海良工阀门整修的危害很大，不仅扰乱市场秩序，还给施工质量带来潜在危险，对社会危害很大。我们只知道伪装的手段还不够，就要识别更生阀。其次，我来告诉你识别更生阀的方法。

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、颜色，更生阀在颜色方面与正规有很大不同。这些廉价材料外观发白，与阀门钢的偏绿明显不同。

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、从钢印来看，纯正阀的钢印在阀门不过热之前，是用钢印技术压制的，所以字体很清晰。更生阀的字体不均匀，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、看油迹，为了伪造翻新后的阀门达到防锈目的，如果在阀门表面涂上厚厚的油污，会降低阀门本身的粗糙度。

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的阀关不上。

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

5、一看闸板，更生阀的闸板一般有磨光的痕迹和锈迹。

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

6、拆下杆的上端螺母和标志，看看里面的锁紧螺母的材质，正规的材质是真的?如果不是的话就是假的。

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.
