The shell 1 is installed on a heat exchange device 2, the heat exchange device 2 is the prior art, hot water and normal temperature water which are not communicated with each other are communicated in the heat exchange device 2 for heat exchange, a water through hole 21 and an installation column 22 are arranged on one end face of the heat exchange device 2, the upper water through hole 21 and the lower water through hole 21 on one side are respectively connected with a water outlet channel 151 and a hot water channel 152 of a water inlet valve, and the upper water through hole 21 and the lower water through hole 21 on the other side are connected with a water outlet valve (not shown in the figure). The shell 1 is provided with shell fixing holes 15 penetrating through the front and the rear of the shell, and the shell fixing holes 15 correspond to the mounting columns 22 and are fixedly connected through bolts.
11 intercommunication water course 14 of moisturizing passageway, moisturizing control channel 12 installs moisturizing device 5, moisturizing device 5 can communicate or cut off moisturizing passageway 11 and hot water passageway 152, when the hot water of used cyclically reduces to some extent and need carry out the moisturizing to it, opens moisturizing device 5, and normal atmospheric temperature water just can get into hot water passageway 152 and carry out the moisturizing operation.
The water replenishing control channel 12 is vertically arranged. In this embodiment, 11 perpendicular to water course 14 and the 11 designs towards the front of moisturizing passageway 11, moisturizing control channel 12 is located moisturizing passageway 11 below and both vertical distributions, adopt the mode of perpendicular moisturizing, with bottom plate (not drawing in the picture, the bottom plate is prior art) plane contact, can satisfy sealed requirement completely (easily sealed between plane and the plane), can prevent that the mouse from getting into, still can be used to full premix condensation hanging stove, can prevent the entering of comdenstion water, really realize totally sealedly.
Moisturizing sealing body 52 is including being located the inboard sealing ring 522 of spacing post 521, sealing ring 522's periphery wall is equipped with seal ring groove 5221, moisturizing sealing body 52 is through installing in seal ring groove 5221O type circle and moisturizing control channel 12 inner wall sealing connection. The inner wall of the water replenishing control channel 12 is provided with a step part, and the water replenishing sealing body 52 is arranged at the inner end surface of the sealing ring 522 until abutting against the step part of the inner wall of the water replenishing control channel 12.
The water replenishing sealing body 52 is in threaded connection with the inner wall of the water replenishing control channel 12, and the threaded part of the outer wall of the water replenishing sealing body 52 is positioned on the inner side of the sealing ring 522.
Moisturizing passageway 11 can be sealed to block up in moisturizing seal 52's the inner so that moisturizing passageway 11 and hot water passageway 152 cut off, and moisturizing sealing washer 56 is installed to moisturizing seal 52's the inner, and moisturizing passageway 11 includes rather than the moisturizing passageway by pass 114 that communicates, and moisturizing sealing washer 56 can be sealed to block up moisturizing passageway by pass 114.
The moisturizing seal 52 is including being located the inboard transition ring 523 of spacing post 521, the transition ring 523 is located between spacing post 521 and the sealing ring 522, and the outer wall of transition ring 523 is equipped with transition ring convex body 5231, moisturizing handle 51 is including being located the inboard handle convex body 512 of handle spacing portion 511, the external diameter of transition ring convex body 5231 is greater than the internal diameter of handle convex body 512, the handle convex body 512 can cross transition ring convex body 5231 when the spacing portion of handle 511 moves along spacing post 521. The cooperation of the handle protrusion 512 and the transition ring protrusion 5231 prevents the refill handle 51 from falling down during normal use, and when the refill handle 51 needs to be used, only a certain force is needed to pull the refill handle 51 downward.
The limit screw 53 is in threaded connection with the outer end of the water supplementing sealing body 52, and the water supplementing handle 51 can move along the water supplementing sealing body 52 and move outwards to be limited on the limit screw 53.
