Abstract
The invention discloses a sanitary anti-freeze faucet which comprises a faucet valve body, a faucet switch arranged at the water outlet of the faucet valve body, and a discharge valve arranged on the water inlet pipe of the faucet valve body. During the process of hand washing, water flows through the faucet switch to prevent the faucet switch from being contaminated by dirt hands and thus to avoid secondary contamination. When the faucet is not used, the discharge valve allows the water inside the water inlet pipe to flow back to empty the water inlet pipe, thereby avoiding frost crack failure of the water inlet pipe in cold winter. Therefore, the faucet can also be used in cold winter with less maintenance cost of broken water pipes. The invention has the advantages of simple structure, convenient and sanitary use and low cost; and is well accepted by users.
Description
Technical field
The present invention relates to a kind of water tap, relate in particular to a kind of sanitary antifreezing tap.
Background technique
Present water tap, to water tap be opened with dirty hand before using, such adhere on the water tap unavoidably with dirty, after washing hand, with clean hand water tap is shut, the hand of wash clean touches contaminated addle tap so originally, cause secondary pollution, people have invented inductive water tap at the shortcoming of above-mentioned water tap, but this water tap costs an arm and a leg, and general crowd is difficult to accept.
Secondly, the interim water tap that supplies water, in the winter of cold, as easy as rolling off a log being frozen in makes water pipe from freezing crack easily, causes a large amount of leaking, and wasted water resources, increased maintenance expenses.
Summary of the invention
Technical problem to be solved by this invention provides a kind of sanitary antifreezing tap, with the secondary pollution that solves the adversary and in season of cold the technical problem with the bursting by freezing of water tap water pipe.
For solving the problems of the technologies described above, technological scheme of the present invention is: sanitary antifreezing tap, comprise tap valve body, be installed in the water tap on the described tap valve body, described water tap is installed in water outlet place of described tap valve body, on the intake pipe of described tap valve body exhaust-valve is installed.
As a kind of improvement, described water tap comprises the valve gap that is installed in described tap valve body water outlet place, the center of described valve gap has tapped through hole, the adjusting screw rod that is complementary with described tapped through hole, the end that described adjusting screw rod stretches out water outlet is installed with rotatable handle, the other end of described adjusting screw rod is connected with the depression bar that seal ring is housed, and described valve gap is provided with some through holes that communicate with tap valve body inside.
As further improvement, described exhaust-valve comprises the valve body that is fixed on the described intake pipe, described valve body is provided with inner chamber, described inner chamber is communicated with described intake pipe and atmosphere, described inner chamber is the convergence shape with described intake pipe and the atmosphere place of connection, be placed with ball float in the described inner chamber, the diameter of described ball float is greater than the diameter of described two convergences place.
Owing to adopted technique scheme, sanitary antifreezing tap comprises tap valve body, is installed in the water tap on the described tap valve body, described water tap is installed in water outlet place of described tap valve body, on the intake pipe of described tap valve body exhaust-valve is installed; When washing one's hands, water is earlier through water tap, prevented that so dirty hand from splitting the pollution of water tap, solved secondary pollution problem, being provided with of exhaust-valve can make water tap time spent not, water in the intake pipe refluxes, make intake pipe not have water, can prevent from like this winter in cold from, water tap also can be used in the winter of cold, save the maintenance expenses of the water pipe that breaks again the intake pipe bursting by freezing, the present invention is simple in structure, the operation hygienic and convenient, and cost is low, and the crowd of any use can be accepted.
Description of drawings
Accompanying drawing is the structural representation of the embodiment of the invention.
Embodiment
As shown in drawings, sanitary antifreezing tap comprises tap valve body 1, is installed in the water tap 2 on the described tap valve body 1, described water tap 2 is installed in water outlet place of described tap valve body 1, on the intake pipe 5 of described tap valve body 1 exhaust-valve 6 is installed.
Described water tap 2 comprises the valve gap 21 that is installed in described tap valve body 1 water outlet place, the center of described valve gap 21 has tapped through hole, the adjusting screw rod 22 that is complementary with described tapped through hole, the end that described adjusting screw rod 22 stretches out water outlet is installed with rotatable handle 23, the other end of described adjusting screw rod 22 is connected with the depression bar 4 that seal ring 3 is housed, and described valve gap 21 is provided with some through holes 24 that communicate with tap valve body 1 inside.
Described exhaust-valve 6 comprises the valve body 61 that is fixed on the described intake pipe 5, described valve body 61 is provided with inner chamber 62, described inner chamber 62 is communicated with described intake pipe 5 and atmosphere, described inner chamber 62 is the convergence shape with described intake pipe 5 and the atmosphere place of connection, be placed with ball float 63 in the described inner chamber 62, the diameter of described ball float 63 is greater than the diameter of described two convergences place.
Working principle of the present invention is:
When washing one's hands, the tap 2 of fetching boiling water, water flows through water tap 2 earlier, dirty hand can be rinsed well the pollution of water tap 2, after hand washing is clean, water tap 2 is closed, solved adversary's secondary pollution problem, simultaneously, water tap is pushed ball float 63 top of inner chamber 62 to by the pressure of water when supplying water, the hole plug that inner chamber 62 top convergent are identical with atmosphere seals, when not supplying water, pressure in the intake pipe 5 produces pressure difference, under the effect that changes pressure and ball float 63 gravity own less than barometric pressure at this moment, ball float 63 produces displacement, air enters intake pipe 5 through inner chamber 62, and water generates refluxes, and the existence of water is not being arranged in the intake pipe 5, can prevent winter, with water pipe from freezing crack in cold.
