Control valve, controls the flow direction of recirculated water.
As a further illustration of the above scheme, the pipeline connection valve uses three-way pipeline structure.
The pipeline connection valve includes straight length and the vertical pipeline section vertical with straight length, and control valve core is arranged on vertically
Pipeline section, one-way control valve is arranged in straight length.
Further, one-way control valve includes being built-in with the valve core shell of cavity, is arranged on the unidirectional of valve core shell inside cavity
Valve element, the upper and lower side of valve core shell is respectively arranged with throughbore, and nonreturn valve core is provided with the piston portion of backstop lower end throughbore
With the guide rod portion that cooperation is patched with upper end throughbore activity, guide rod portion is arranged with spring.
Further, the control valve core is fixed in pipeline connection valve by rotating shaft, and control valve core is provided with appearance
The through hole that current pass through, control valve core is connected with adjusting knob or handle.
The beneficial effect that the utility model can be reached using above-mentioned technical solution is：
The utility model use on the cold water branch road and hot water branch road of distalmost end water spot respectively set have cut-off and
The pipeline connection valve of unidirectionally controlled two kinds of functions, is connected as one two pipeline connection valves by circulating water pipeline, the company of reducing
Jointed tubular workpieces quantity, reduces transformation pipeline cost and leak risk；Compared to common cut-off angle valve and ball valve, the structure latus rectum is more
Greatly, it is ensured that water-carrying capacity demand during system operation.
