The utility model is compared the beneficial effect that is produced with background technology:
1, because the utility model adopts antifreeze pressure limiting valve, described antifreeze pressure limiting valve comprises antifreeze pressure limiting pipe, spring, sealing ring, end cap, mobile, mobile is by the sealing ring and the antifreeze pressure limiting seal of tube, end cap is provided with through hole, end cap is connected in the end of antifreeze pressure limiting pipe, spring places in the antifreeze pressure limiting pipe and between mobile and end cap, and the structure that the water inlet of antifreeze pressure limiting valve by antifreeze pressure limiting pipe is communicated with water pipe is so it can be antifreeze effectively under the power failure situation.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the annexation enlarged diagram of antifreeze pressure limiting valve 2 and water pipe 1 among Fig. 1.
Fig. 3 is the antifreeze pressure limiting valve 2 of another kind of structure among Fig. 1 and the annexation enlarged diagram of water pipe 1.
The specific embodiment: referring to accompanying drawing 1, accompanying drawing 2, shown in the accompanying drawing 3, present embodiment comprises water pipe 1, antifreeze pressure limiting valve 2, magnetic valve 13, controller 14, heat exchanger 15, smoke exhaust pipe 16, controller 14 electrically connects with magnetic valve 13, antifreeze pressure limiting valve 2 comprises antifreeze pressure limiting pipe 4, spring 8, sealing ring 9, end cap 10, mobile 17, the quantity of sealing ring 9 can be more than one, as one, two, three, four etc., mobile 17 is by the inner wall sealing of sealing ring 9 with antifreeze pressure limiting pipe 4, end cap 10 is provided with through hole 12, end cap 10 is connected in the end of antifreeze pressure limiting pipe 4, spring 8 places in the antifreeze pressure limiting pipe 4 and between mobile 17 and end cap 10, antifreeze pressure limiting valve 2 is communicated with water pipe 1 by the water inlet 3 of antifreeze pressure limiting pipe 4.Antifreeze pressure limiting pipe 4 front ends can be provided with step 7, and antifreeze pressure limiting pipe 4 is communicated with water pipe 1 by step 7.
Antifreeze pressure limiting valve 2 can be installed in the corner of heat exchanging water pipe 11 in the water pipe 1, also can be installed in the water pipe 1 on water inlet pipe 5 or the outlet pipe 6.Antifreeze pressure limiting valve 2 is installed in antifreezing effect on the heat exchanging water pipe 11 and is better than antifreeze pressure limiting valve 2 and is installed on water inlet pipe 5 or the outlet pipe 6, and a plurality of antifreeze pressure limiting valves 2 are installed in antifreezing effect on the heat exchanging water pipe 11 and are better than single antifreeze pressure limiting valve 2 and are installed on the heat exchanging water pipe 11.Antifreeze pressure limiting pipe 4 also can be respectively and heat exchanging water pipe 11, water inlet pipe 5, outlet pipe 6 global formations, and two to 12 antifreeze pressure limiting valves 2 can be installed on the water pipe 1.In the present embodiment, four antifreeze pressure limiting valves 2 are installed in respectively on heat exchanging water pipe 11 corner, water inlet pipe 5 and the outlet pipe 6.
