The utility model is accomplished through following technical proposal: a kind of complete ceramic freedom from repairs water tap, structure comprise handle, valve rod and place bonnet and two pairs of sealing pairs of valve casing and spring; The interior edge face that it is characterized in that bonnet is a upper valve base, is sintered to the last diaphragm seal of one and the last sealing pair that upper valve base is formed valve rod with the valve rod middle part; The inner bottom plate of valve casing is a lower valve base, and it is secondary that following open-shut device and valve casing inner bottom plate are formed lower seal; The spring endoporus is passed in the lower portion of valve rod, and the square termination of stretching out is inserted in down in the square blind hole at open-shut device center, can in blind hole, move up and down and rotate open-shut device down; The spring that the upper-lower seal pair is between the same axis compresses simultaneously.

Open-shut device rotates 90 ° together under handle with sleeve and valve rod drive; Two fan-shaped pylones on the following open-shut device align with two scalloped recess on the valve casing inner bottom plate lower valve base; Groove is connected with the outlet at valve casing inner bottom plate center, the medium valve shell cavity of from the medium channel of water tap, flowing through at this moment, the fan-shaped pylone on the following open-shut device, the groove on the valve casing inner bottom plate;, accomplish the unlatching of water tap after the outlet at valve casing base plate center is flowed out; Otherwise when 90 ° of valve rod revolutions, atresia plane partly on the following open-shut device is under the effect of spring pressure; Be adjacent to the plane on every side of two scalloped recess that cover on the valve casing inner bottom plate, accomplish closing of water tap.

Freedom from repairs is following the completion: the interior edge face of bonnet and the inner bottom plate of valve casing itself are respectively the secondary valve seats of upper-lower seal, just do not need sleeve pipe and plastic washers in the therefore novel cavity volume; Be that valve rod and last diaphragm seal are the potteries that is sintered to one again, and form the sealing pair of valve rod, so also the plastic cement seal ring need be installed between valve rod and bonnet space with bonnet; The 3rd, upper-lower seal pair and valve rod are on the same axis; Be enclosed within the stainless steel spring of valve rod lower half portion, compress the upper-lower seal pair simultaneously, not only hard but also sliding ceramic seal pair is durable wear very; The effect of spring makes them have the self compensation function of wear extent; All the time let sealing pair keep being adjacent to state, the situation of evaporating, emitting, dripping or leaking of liquid or gas can not take place, structure in sum and performance make the function that the utlity model has freedom from repairs.

The utility model compared with prior art has advantage and effect: adopt such scheme, make novel raw material for the clay with low cost that all has in all parts of the country, practice thrift the metals resources of high energy consumption; Low-carbon environment-friendly; Handle, valve rod, valve casing, the two pairs of sealing pairs are not only hard but also sliding pottery, durable wear, and the self compensation function that has wear extent again need not keeped in repair; The situation of evaporating, emitting, dripping or leaking of liquid or gas can not appear in water tap relatively; Can not produce corrosion thing and plastic cement flavor, even can be made into the water tap of high-grade general anesthesia oak oak, be particularly suitable for being installed on the domestic wine bucket; Owing to do not have sleeve pipe, rubber cushion and O-ring seal in the novel cavity volume with on the valve rod; Therefore relatively simple for structure; Pottery valve casing outer surface also can be made the frost flower porcelain of various colour images, is a desirable handy freedom from repairs water tap of having the industrial art ornamental value again in fact.
