The purpose of valve acceptance?
Through acceptance, the quantity Check Valve and appearance of the delivered valve can be checked and checked to prevent the appearance of quality damage and lack of quantity during transportation, loading and unloading, etc., and the actual situation of the delivered valve can be grasped. If the order contract does not conform to the order, the quantity is short, the specification and model are wrong, and the appearance has obvious quality problems, etc., it can promptly propose rejection and return to the supplier, and promptly contact the purchasing department to deal with the problem as soon as possible. In addition, the acceptance can also create conditions for the correct classification and storage of valve materials and the correct putting into use.
What is accepted?
The acceptance of valve materials includes: packaging, marking, appearance quality, specification, model, quantity, etc.

Smell, the main reason for the smell of plastic products is the use of recycled materials and poor-quality additives. The pungent odor emitted by products with odors can harm the human respiratory system, so it is best not to use them.
Look at the appearance. If the product has rough appearance, molding defects, incorrect color, impurities, and poor printing quality, it is best not to use it. Products with unqualified appearance quality will affect consumers' visual experience, and at the same time, appearance is a reflection of internal quality. Products with unqualified appearance often have poor internal quality, which affects their use. Unsatisfactory printing quality will affect the appearance, but will fade and contaminate other items.
Try it out. Some products are very bright in color in order to attract consumers' attention. Pigments of poor-quality dark products will squeeze out during use, and these pigments are generally industrial pigments. Consumers can check by themselves whether the selected dark color product is qualified: pour a little vinegar on the absorbent cotton ball, and then wipe it back and forth 100 times in contact with the food surface. If the absorbent cotton ball is stained with color, it means that the product is unqualified.
