Pressure proportional mixing device (vertical foam tank)
Product name: Pressure proportional mixing device (vertical foam tank)
Specification model:PHYM series
Basic function:Supply source of foam mixture
Simple description:The mixing ratio is stable and reliable, and the pressure loss of the pipeline is less
1. Product description
PHYM series pressure proportional mixing device (hereinafter referred to as mixing device) has the characteristics of stable performance, wide applicable flow pressure range and low pressure loss. It consists of various high, medium and low expansion foam fire extinguishing systems. The mixing device can be divided into horizontal type and vertical type according to the installation form, and can be divided into three types according to the internal structure: integral type, partition type and diaphragm type. According to the operation form, it can be divided into manual operation and automatic operation (electric or pneumatic). ), the company's factory standard configuration is AC220V electric ball valve. The storage tank volume varies from 1m3 to 10m3.
2. Product classification
