A, automatic sprinkler model
1. What types of fountain nozzles are there?
Commonly used are nozzles with diameters of DN25 and DN40. Nozzles are also divided into straight nozzles, petal nozzles, hemispherical nozzles and many patterns. Look at your specific requirements.
Generally, nozzles with diameters of DN25 and DN40 are used, which are divided into straight nozzles, petal nozzles, hemispherical nozzles and various patterns.
2. Model and specification of nozzle:
The model specification of the nozzle consists of type characteristic code (model), performance code, nominal caliber and nominal working temperature. ZSTZ is the code name of vertical nozzle. Other model codes are as follows:
Universal nozzle: ZSTP
Hanging nozzle: ZSTX
Vertical side wall sprinkler: ZSTBZ
Hanging sidewall sprinkler: ZSTBX
Ordinary side wall sprinkler: ZSTBP
Sprinkler for horizontal side wall: ZSTBS
Flushing nozzle: ZSTDQ
Embedded nozzle: ZSTDR
Hidden nozzle: ZSTDY
Dry nozzle: ZSTG
The quick response nozzle and the special response nozzle start with "K" and "T" respectively, and are separated from the performance code with "﹣", while the standard response nozzle is not preceded by a symbol; For the nozzle with coating and nozzle with waterproof cover, add "C" and "S" before the performance code and separate them with "-"."
Second, the automatic sprinkler system (K=80) What does K=80 mean here?
K refers to the discharge coefficient of the nozzle, indicating how many liters of water the nozzle can spray per second. K=80, which means that the nozzle can spray 80 liters of water per second. K=80 is the standard nozzle.
Third, the nozzle classification information
1, burner nozzle (military and civil)
2. Burner nozzle
According to the function of the nozzle, the nozzle can be roughly divided into spray nozzle, oil spray nozzle, sandblasting nozzle, garden watering nozzle, rocker arm nozzle for irrigation in agricultural field, micro nozzle for agricultural greenhouse, industrial dustproof nozzle and special nozzle.
According to the material classification, it can be divided into metal nozzle, plastic nozzle, ceramic nozzle and alloy nozzle.
According to industry classification, it can be divided into petrochemical nozzle, agricultural nozzle, textile nozzle, paper nozzle, environmental protection nozzle, spray nozzle, chemical nozzle, steel nozzle and electronic nozzle.
According to the shape classification, it can be divided into hollow conical nozzle, solid conical nozzle, square nozzle, oval nozzle, fan nozzle, columnar flow nozzle, dual-fluid nozzle, multi-fluid nozzle and so on.
Special industrial nozzles: nozzles, catalytic cracking nozzles, Texaco nozzles, granulation nozzles, sand blasting nozzles, etc.
Generally speaking, the nozzle in the advertising industry mainly refers to the parts in the printer used to store printing ink and finally complete printing.
As for the models of sprinkler heads, we can find that sprinkler heads are not only divided into many models, but also classified according to the actual use of users and the needs of different scenes. In addition, we also analyzed and introduced the knowledge about other nozzles, such as burner nozzles and non-burner nozzles, which also play a very important role in many occasions.
