1.The cold-hot alternate constant pressure water supply system is designed according to 

the requirements of customers, and is mainly suitable for the use of cold and hot water i

ntegrated capacity test for valve types. With PID frequency conversion and constant pressure

 water supply, under the pressure range of 0-2.0 mpa, the life test of the tested valve body is 

carried out under the condition of specified cold and hot water use with 5s on, 5s off and one

 on-off. The main components of the test equipment are: central control system, test frame,

 constant pressure water supply device, heat and cold constant temperature control system

2.The testing machine is assembled with 40 aluminum frame, the sheet metal is assembled 

with 304 # , and the inner water tank and pipeline are welded with 304 # steel. Built-in hot and

 cold water tank respectively supply water, the use of circulating water on the test water respectively back to the hot and cold water tank
