Description
Technical field
The present invention relates to the passive automatic transfer valve of a kind of heating system, belong to the hot-water heating manufacturing field of equipment.
Background technique
Existing heat supply in winter, owing to adopted the automatic temperature control valve gate technique, indoor temperature has obtained effective control, has avoided the waste of heat energy.But in practice, still there are some defectives in current heating systems, and for example the return water temperature of thermal medium is very high sometimes, but still by the defeated back boiler room of long water return pipeline, heat energy is not fully utilized; When particularly ambient temperature uprised owing to the commentaries on classics of weather is warm, the temperature difference of entering water temp and return water temperature was sometimes very little, has caused the bigger waste of heat energy; If stop or reducing the supply of thermal medium this moment, and backwater is re-circulated to radiator, the heat energy in the backwater is discharged; When return water temperature is lower than certain value, open or increase the flow of thermal medium again automatically again, will well heat energy utilization be got up.
Summary of the invention:
The purpose of this invention is to provide the passive automatic transfer valve of a kind of heating system.
Technological scheme of the present invention is achieved like this, and mainly comprises valve body, piston assembly, inlet valve A, outlet valve B, C, attachment cap, continuous motion stem, valve gap, valve bonnet, adjusting nut, last memory alloy, plate washer, reset spring, following memory alloy, reset spring, bonnet; The basic structure of two outlet valve B, C is the same; Described water intake valve A is connected with the water return pipeline of heating system, and outlet valve C is connected with pipeline behind the heat meter, and outlet valve B is connected with the water return pipeline of getting back to the boiler room; Described piston assembly mainly comprises upper-lower seal circle, piston body, continuous motion stem; The middle part has a plate washer, continuous motion stem to pass upper-lower seal circle on piston body and the assembly from top to bottom on the described continuous motion stem; Described continuous motion stem is connected with attachment cap movingly by sealing gasket, and described attachment cap is connected with valve gap by screw thread, and valve gap is connected with valve body with screw thread by sealing gasket; Between the baffle plate on described attachment cap and the continuous motion stem: on the B valve reset spring is installed, on the C valve thermosensitive element is installed down; The top of described baffle plate: the B valve is equipped with thermosensitive element, and the upper end of C valve is equipped with reset spring, and the upper end of last thermosensitive element and reset spring is conditioned nut respectively and withstands; Described adjusting nut is connected with valve bonnet by screw thread; The over top of adjusting nut has an elongated slot, by with the be compressed degree of screw-driver turn elongated slot can regulate to last thermosensitive element and reset spring; Valve bonnet is connected with valve gap by screw thread, and described thermosensitive element can adopt temperature memory alloy or thermometer bulb; Thermosensitive element up and down in described B, the C valve all is in contraction state when return water temperature is low; The seal ring of the lower end of B valve inner carrier assembly leaves the water outlet in the valve body at this moment, and from the backwater that the A mouth flows to, the heating that flows into the boiler room through the B valve is established each; When the return water temperature of heat dissipation equipment outflow was higher, thermosensitive element expanded, and promotes baffle plate and move downward in the B valve, the promotion piston assembly moves downward, and under the acting in conjunction of hydraulic pressure, forces the seal ring of piston assembly lower end, block the water outlet in the valve body rapidly, the B valve cuts out; The C valve is switched to be opened.When the present invention works without any need for outer power.
The invention has the beneficial effects as follows that the thermal medium of the higher temperature that the present invention can be flowed out heat dissipation equipment carries back the heat dissipation equipment import to reuse again, the backwater that temperature is lower is directly sent the boiler room back to; Device does not need outer power when automaticallying switch.
