Because the heating sheet device is arranged at the valve core, the temperature of the valve core and the valve opening can be kept above 0 ℃, the freezing is prevented, and the smooth water discharge is ensured.
The valve seat, the sealing seat and the water inlet sealing cover are arranged and matched with the sealing ring, so that water is prevented from entering the heating space on one hand, and air or water in the tank body is prevented from leaking outwards under the condition that the valve opening is closed on the other hand, and the sealing performance is improved.
In the above embodiment, the provision of the water inlet seal cover is a preferable mode of the present embodiment, and the fin device 11 is mounted to form the heating space 10. Under the condition that the heating plate device 11 is not required to be installed, the water inlet sealing cover can be omitted, and only a common valve core is used. The mode still has the advantages of reducing the part of the valve body exposed outside the tank body, reducing the possibility of being impacted by foreign objects and reducing potential safety hazards.
