Abstract

The utility model relates to a mixing tap which is arranged on wall and connected with cold and hot water pipes, comprising a valve body which is provided with a mixing valve core in the inner part, cold and hot water inlet channels which are communicated with the valve body, a base board, an O-shaped rubber washer, an inner gasket, a pressing nut, a partition board and a top cover. Cold and hot water sources are divided into two cavities by the partition board between the top cover and the base board. Whether two water pipes on the wall come out from the wall vertically or not, and whether the distance between the two pipe is large or small, the two water pipes can be matched and fixed perfectly with the arc opposed face between the pressing nut and the inner gasket. No connecter needs to be arranged between the cold and hot water pipe and the cold and hot water channel. The position of the mixing valve core can be altered through opening and regulating a mixing handle, in order to obtain water with desired mixing temperature. The utility model has the advantages of convenient installation, low requirement towards inbuilt water pipe, close fitted installation with wall surface, beautiful shape and long durability.

Description

Mixing tap

Technical field

The utility model relates to the combustion taps that can be connected with hot and cold water pipe.

Background technique

Traditional hot water or cold water's mixing tap need be regulated hot and cold water pipe curved and that be preset on the wall by one and join, though regulate curved can adjusting within the specific limits, reach the cool and hot water pipe purpose of connecting on mixing tap and the wall, but the common metope of can't being close to is installed, and influences phenomenon attractive in appearance; Also have, can install in order to reach, higher to the construction technology quality requirement of burying hot and cold water pipe underground, the wall end that goes out that is hot and cold water pipe should be vertical with metope, and the distance between two water pipes has comparatively strict requirement, otherwise mixing tap with can't reach straight line being connected of cool and hot water pipe and be connected, the copper connecting tube working life of curved and mixing tap is regulated in influence.

The model utility content

The utility model purpose is to design a kind ofly buries less demanding, the convenient mixing tap that metope is installed of installing, realize being close to underground to cool and hot water pipe.

In comprising, establishes the utility model the valve body of mixed valve core, the hot water or cold water's intake tunnel that is communicated with valve body, base plate, O shape rubber washer, internal gasket, gland nut, dividing plate, loam cake, described loam cake is connected the back of valve body, on cover and offer the hot water or cold water's water intake that is communicated with hot water or cold water's intake tunnel respectively; Offer two bottom plate holes on the base plate, the aperture of each bottom plate hole is big than wall two water pipe external diameters, outside every wall water pipe, distinguish overcoat O type rubber washer and internal gasket successively, the upper surface of internal gasket is the spill cambered surface, on internal gasket, arrange the gland nut that is provided with suitable mutually of wall water pipe outside thread, the lower surface of gland nut is convex-shaped arc surface, the radius of curvature of this convex-shaped arc surface and suitable mutually of the spill cambered surface radius of curvature of internal gasket; Loam cake is fixedlyed connected with base plate by set screw, arranges dividing plate between loam cake and base plate, and two wall water pipes lay respectively at the both sides of dividing plate, and hot water or cold water's water intake lays respectively at the both sides of dividing plate.

The utility model is divided into two chambeies by dividing plate with hot and cold water source between loam cake and base plate, no matter whether wall two water pipes vertically go out wall is buried underground, no matter it is apart from size, can both be respectively by gland nut and arc opposing side between internal gasket intactly cooperate, fixing, need not between hot and cold water pipe and hot and cold water intake tunnel, link to be set, mix handle by opening, regulating, change the position of mixed valve core, just can obtain required mixing temperature water outlet.The utlity model has following superiority: the convenient installation, less demanding to burying water pipe underground; Can be close to metope and install, attractive in appearance; Improve product working life.

For preventing to leak, the utility model is arranged seal ring between base plate and loam cake.

Install for convenient, provide held stationary to support to dividing plate simultaneously, groove is set respectively on the utility model loam cake, the base plate, described dividing plate passes through recess supports.

Bury the unconventional installation of hot and cold water pipe underground for adaptation, promptly cool and hot water pipe is counter establishes, and the screw piece dividing plate that the utility model can be by S-shaped section transfers to cold water inlet with respect to the right side with left side cold water; When (promptly hot-water line is buried in the left side underground, cold water pipe is buried on the right side underground) is installed routinely, only need select the linearly dividing plate of shape of section for use.

The utility model also can be provided with the rotation catch at water outlet.By manual action, select opening or closing of the mouth of a river to the rotation catch.When opening state, to mixing the control of handle, can reach normal use hot and cold water purpose again; When closed condition, lift the mixing handle, it is logical to make hot and cold water form connection in mixed valve core.As hot-water line is communicated with water heater, can directly in water heater, replenish cold water.

Specific embodiment

Among the figure, 1 water outlet, 2 valve bodies, 3 mixed valve cores, 4 mix handle, 5 cold water intake tunnels, 6 hot water intake tunnels, 7 grooves (), 8 dividing plates, 9 cold water inlets, 10 loam cakes, 11 set screws, 12 seal rings, 13 base plates, 14 bottom plate holes, 15 water pipes (), 16O type rubber washer, 17 internal gaskets, 18 grooves (two), 19 gland nuts, 20 water pipes (two), 21 water inlet of hot water, 22 connect inner screw tooth hole, 23 rubber pads, 24 rotation catch.

Offer two bottom plate holes 14 of diameter on the base plate 13, cross one another straight shape and S connected in star (two) 18 greater than water pipe () 15 and water pipe (two) 20.To be enclosed within on two water pipes (), (two) 15 and 20 outside rubber pad 23, the base plate 13 successively during installation, on two water pipes (), (two) 15 and 20 respectively successively overcoat O type rubber washer 16, upper surface be the internal gasket 17 of indent, and by lower surface be convex, be provided with gland nut 19 with suitable of water pipe outside thread with packing ring 16, internal gasket 17 packings on water pipe (), (two) 15,20.
