The working principle of the utility model is as follows:
When the numerical value shown on closed water system pressure gauge reaches the numerical value for needing dosing, pressure gauge is turned off manually first
Manually-operated gate on connector, and closed water system pressure gauge is removed from pressure tapping, then unidirectional valve union is installed to
In pressure tapping, and the both ends of rubber hose are connect with unidirectional valve union and dosing pump respectively, then by the suction of dosing pump
Medicine mouth is put into flask for medicinal preparations, and opens manually-operated gate, and equipment installs at this time；After installing equipment, electricity is connected in remote control first
Source, medicament successively enter closed water system circulation pipe through medicine inhaling mouth, dosing pump, rubber hose, unidirectional valve union, pressure tapping
Road, and as closed water system water circulating pump and recirculated cooling water are sufficiently mixed uniformly, remote control disconnects power supply after dosing, then
Secondary closing manually-operated gate, then holding tapered calotte prevents the medicament splash that pressure is had in rubber hose, and removes check valve
Closed water system pressure gauge is finally installed in pressure tapping by connector, and is again turned on manually-operated gate and is completed entirely to add
Medicine process.
The beneficial effects of the utility model are:
The utility model is dexterously solved simultaneously by the way of adding check valve and tapered calotte on dosing pipe
The problem of cooling water suck-back existing for during closed-type circulating cooling water system dosing and medicament splash, both avoid circulating cooling
The loss of water, in turn avoids the waste of medicament, to ensure that the stability and continuity of closed-type circulating cooling water system operation.
Meanwhile the utility model is designed using integrative installation technology, is not only convenient for transport and on-site assembly, and easy to operate, is saved
Dosing cost.
