Mouthful, the other end of the water supply side cavity is provided with the water supply side delivery port being connected with household internal heating pipeline；The water supply
Side inside cavity is provided with the regulating valve of regulation water supply side cavity uninterrupted, the water supply close to one end of water supply side water inlet
Side inside cavity is provided with the seal plate opened and closed by water flow pressure control close to one end of water supply side delivery port；The backwater side chamber
One end of body is provided with the backwater side delivery port being connected with municipal return pipe, and the other end of the backwater side chamber body is provided with and family
The connected backwater side water inlet of heating pipeline inside front yard；Backwater side inside cavity is provided with water check valve and only allowed by backwater
The check valve that side water inlet circulates to backwater side delivery port.
Further, the seal plate includes the sealing plate and back-moving spring for current of stopping, and sealing plate is normally opened structure, multiple
Position spring is arranged on sealing plate close to the side of water supply side delivery port.
Further, the regulating valve is flow valve.
Further, the water check valve is ball valve.
Preferably, water supply side cavity and backwater the side chamber body is provided with share common sidewalls, is provided with the share common sidewalls
The passage of water supply side cavity and backwater side chamber body is connected, normally closed pressure-reducing valve is provided with the passage.
Further, the passage is arranged between regulating valve and seal plate.
Preferably, the water supply side cavity and backwater side chamber body are two individual cavities, the water supply side cavity and backwater
Connecting pipeline is provided between side chamber body, normally closed pressure-reducing valve is provided with the connecting pipeline.
Further, the joint portion of connecting pipeline and the water supply side cavity is between regulating valve and seal plate.
The beneficial effects of the invention are as follows：The present invention is by regulating valve, the setting of seal plate, in leak because flow velocity is accelerated,
Water jet propulsion sealing plate, compression reseting spring, realize the effect in self-closed water route；Now household internal heating pipeline is because of leak
And hydraulic pressure reduces, the problem of setting of check valve avoids suck-back municipal administration backwater liquid in pipe, large-scale water leakage effectively prevent；
The setting of flow valve makes this programme be applied to the environment of the different heating hydraulic pressure in each department, normally makes to stop by adjusting flow during heating
Water plate reaches closes critical, raising sensitivity reduction water leakage automatically；Water supply side cavity and backwater side chamber body phase are intercommunicated, and
Be provided with normally closed pressure-reducing valve in the case of normal heating, this can when municipal water supply pipe abnormal pressure seal plate is not opened,
By opening pressure-reducing valve, allow part water to flow directly to backwater side chamber body, then directly drained by municipal return pipe, be water supply side
Cavity depressurizes, and reaches the purpose normally to heat.
