Anti-frozen water faucet

Abstract

The invention provides an anti-frozen water faucet and belongs to the technical field of water heating pipe fittings. Through the anti-frozen water faucet, the problem that an existing water faucet isfrost-cracked easily in winter is solved. The novel anti-frozen water faucet comprises a water faucet body, a hand shank, a water inlet and a water outlet. The water faucet body is internally provided with a flow channel cavity. The water faucet body is provided with a rotary shaft driven to rotate by the hand shank. The upper end of the rotary shaft is connected with the hand shank. The lower end of the rotary shaft extends into the flow channel cavity. The tail end of the rotary shaft is fixedly connected with an eccentric wheel arranged eccentrically. A valve rod driven to transversely move by the eccentric wheel is transversely arranged in the flow channel cavity. A partition board and a sealing seat which are distributed in a spaced mode are arranged in the flow channel cavity. A spring is arranged between the partition board and the sealing seat. The valve rod is sleeved with the spring. The top end of the valve rod penetrates through the partition board to make contact with theeccentric wheel. The tail end of the valve rod penetrates through the sealing seat to be provided with two limiting rings integrated with the valve rod. A silica gel sealing ring in sealing fit withthe sealing seat is arranged between the two limiting rings. The anti-frozen water faucet has the advantages of being simple in structure, long in service life and free of water storage.

Description

technical field [0001] The invention belongs to the technical field of plumbing pipe fittings, and relates to a faucet, in particular to an antifreeze faucet. Background technique [0002] Tap water is closely related with people's daily life, and the use of tap water has brought great convenience to people, and faucet is a kind of device that tap water is realized opening, closing and control outlet water flow. The valve cores of the faucets currently on the market are all installed on the main body close to the water outlet, and the outdoor temperature in winter in the north is very low, and the tap water in rural areas is controlled by the water company for regular water supply, that is, during the time when the temperature is high at noon during the day Water supply, cut off when the temperature is low at night. Once there is residual water in the faucet, it will be frozen at night. In order to prevent tap water from remaining in the pipe faucet, you need to manually op...
