Abstract

The invention provides an anti-freezing explosion-roof valve used for a civil water-heating stove and the civil water-heating stove. The anti-freezing explosion-roof valve comprises a valve body screw cap (101), a valve body housing (102), a valve body embedded head (103), an explosion-roof membrane (104), a membrane fastening part (105), a spring (106) and a spring non-return part (107), wherein the valve body housing (102) is cylindrical, and outer threads are arranged on the side wall of the valve body housing; one end of the valve body housing (102) is fixedly arranged at one side of the valve body screw cap (101), and inner threads are arranged on the side wall, close to the valve body screw cap (101), of the valve body housing (102); a ring-shaped groove (1021) is formed inside the side wall of the valve body housing (102); the valve body embedded head (103) is cylindrical; one end of the side wall of the valve body embedded head is equipped with a first ring-shaped bump (1031) which is bulged outwards, and the other end of the side wall of the valve body embedded head is equipped with a second ring-shaped bump (1032) which is inwards bulged; and inner threads are arranged on the side wall of the valve body embedded head. According to the scheme, when circulating water in a water gasket is iced, ignition is carried out to burn the stove, so that the anti-freezing explosion-roof valve still can release pressure timely to achieve an explosion-roof function.

Description

technical field [0001] The present application relates to the technical field of civil water heaters, and in particular, relates to an explosion-proof valve with an antifreeze function for a civil water heater, and a civil water heater with the explosion-proof valve. Background technique [0002] At present, according to the current national standard, an explosion-proof valve with an inner diameter of not less than 25mm must be installed above the water jacket of the water heating furnace. When the water heating furnace is under pressure accidentally, the explosion-proof valve diaphragm can burst to relieve the pressure of the stove and play an explosion-proof function, thereby ensuring the safe operation of the heating furnace. [0003] However, the conditions used by the current explosion-proof valve must ensure that the water in the water jacket of the heating furnace is in a fluid state. And when the indoor temperature is lower than zero for a long time and the water in...
