The upper end-hole of described valve body and being positioned at below valve gap is also provided with for preventing the inner cap contacted with magnet with the ferrous impurity that water flows into from water intake, covers the through hole being formed with and can running through magnet frame in described.
Sealing gasket is provided with between the upper end-hole of described valve body and described valve gap.
Described temperature measuring mechanism includes upper end and to be inserted in valve body from the patchhole of body base and to be positioned at the temperature measuring head of water intake side, and described temperature measuring head is locknut by being threaded with described patchhole and can is releasably connected on valve body.
The top of described patchhole and described locknut is provided with seal ring.
The multi-functional reaction type safety check of one of the present utility model, structure is simple, is convenient to implement.Solve existing return valve function single, the problem that heat supply controls automatically can not be applied to, successfully the check function of valve is combined with signal feed back, solves the problem that heating system malice discharges water with accidental water leakage and temperature feedback.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the multi-functional reaction type safety check of one of the present utility model is described in detail.
As shown in Figure 1, the multi-functional reaction type safety check of one of the present utility model, includes valve body 2, and material is casting copper.Being positioned at water intake side in described valve body 2 is provided with for measuring the temperature of the water flowed into and feed back to the temperature measuring mechanism of control system, bearing pin 10 by being arranged on valve body 2 upper end-hole place in valve body 2 is provided with opens water intake when intaking, close the flap 1 that water intake plays one-way valve effect during anhydrous or backwater, material is casting copper.Described valve body 2 upper end-hole is threaded connection the valve gap 5 for sealed upper end mouth, is provided with sealing gasket 4 between the upper end-hole of described valve body 2 and described valve gap 5.Described valve gap 5 is the tube structure of up/down perforation, and by cylindrical shell being divided into upper space and lower space along the cylindrical shell radial interlayer 15 be integrally formed with cylindrical shell, described flap 1 is provided with upper end and extends to the magnet frame 7 that also can be elevated with the swing of flap 1 in valve gap 5 lower space, magnet frame 7 place being positioned at valve gap 5 lower space is provided with magnet 6, the dry reed-pipe 8 coordinated with described magnet 6 for detecting streamflow regime is provided with in the upper space of described valve gap 5, the upper space of described valve gap 5 is sealed by plastic roof 9, described plastic roof 9 has for running through the cable-through hole 14 connecting dry reed-pipe 8 wire.Described dry reed-pipe 8 can also be replaced with the different magnetic induction parts such as proximity switch, Hall switch.
The upper end-hole of described valve body 2 and being positioned at below valve gap 5 is also provided with for preventing the inner cap 3 contacted with magnet 6 with the ferrous impurity that water flows into from water intake, and material is polyethylene.Described inner cap 3 is formed with the through hole that can run through magnet frame 7.
