Abstract

The utility model discloses an assembled type tap with a housing, which is characterized in that a water tap with the functions of cold and hot water inflow and water use is formed by the method that the inside of a body of the water tap is matched with an external decorative housing via the mode of pipe connection. In the water tap, a traditional, complicated, and contaminative integral casting processing does not need to be adopted, the fabrication is convenient, and the cost can be reduced; meanwhile, the decorative housing can be made into various styles; the external shape of the water tap can be changed at will; the interior structure of the body can be made of stainless steel or other materials in which hazardous elements such as plumbum, etc. are not contained; the product can be guaranteed to achieve the strictly controlled environmental protection standard in European and American nations; the problem that lead elements in minute quantities is contained in the materials of water taps made of zinc and copper by traditional technology can directly contact water, and water pollution can be caused can be basically solved. The utility model is suitable for volume production.

Description

The overcoat combined tap

Technical field

The utility model relates to technical field of taps, more specifically to having cold and hot intake-outlet, knockdown water tap.

Background technique

The mixed water of existing hot and cold water generally is made of main body and the spool in main body with the water tap of function, tap main body all adopts casting to make, the dark form grid slotted eye that is provided with various complexity in its main body constitutes cold and hot intake tunnel and exhalant canal, and above-mentioned passage is communicated with cold and hot water intake and water outlet respectively; The Casting Technology difficulty of the tap main body of said structure is big, the brass casting that generally can only adopt low melting point, easily flow, material mixes is made, because the deep inside that the dark form grid slotted eye of various complexity is all cast in main body, mechanical processing difficulty is increased, simultaneously dark form grid easily causes the pore leak when casting and can't find, thereby cause that the situation that hot and cold water leaks takes place, make its difficult quality control; Contain harmful matters such as lead simultaneously in the cast copper, do not meet high-level environmental requirement, therefore this type of water tap of American-European countries's import all will carry out the strictness detection, and the someone adopts on its surface and adopts the mode of the harmful lead element of solvent clean, but can't tackle the problem at its root.

In order to address the above problem, someone adopts stainless steel to cast tap main body, though this has solved harmful matter and the high-quality problems of water tap such as leaded, and its deficiency is arranged equally: 1), adopt stainless steel casting technique difficulty big, complex structure, processing difficulties; 2), product external surfaces has the granule pore, yield rate is low, thereby the cost height, is difficult to form produce in enormous quantities.

Summary of the invention

Technical problem to be solved in the utility model is that to overcome main body be that the water tap producting process difficulty that forms of cast inblock is big, complex structure, processing difficulties, the product appearance has the granule pore, and yield rate is low, be difficult to the deficiency of batch process, and a kind of overcoat combined tap is provided.

Technology solution of the present utility model is as follows:

This overcoat combined tap, comprise osculum, cold water inlet hole, hot water inlet hole, spool that tap main body is provided with, the adjusting handle is established on its top, spool is located on the valve core case, corresponding hole that is provided with is characterized in that on it, and this water tap is by independently inner structure and outer sheathing two-part constitute, osculum on the inner structure, cold water inlet hole, hot water inlet hole all communicate with respective aperture on the valve core case by taking over, and water tap is outside for decorating overcoat.

As the further improvement of such scheme, on taking over, water outlet of the present utility model also can be connected with water knockout drum.

The valve core case of main body inner structure can or be screwed into one by valve core housing body and the welding of spool base, also can directly adopt whole the manufacturing to be shaped.

Described decoration overcoat constitutes by the housing more than 2 is fixedly connected; Decorate overcoat and can pass through the stainless steel materials drawing, also can adopt other material technology shapings such as injection moulding.

Outstanding effect of the present utility model is: tap main body of the prior art adopts cast inblock, and the dark form grid slotted eye that is provided with various complexity in it constitutes cold and hot intake tunnel and exhalant canal, is communicated with cold and hot water intake and water outlet respectively by passage; Complex process, yield rate is low, compared with prior art, the utility model adopts housing to decorate overcoat, adopt the mode of taking in its internal structure, do not adopted the complicated integral casting process that pollutes of tradition, but the drawing of housing overcoat, processing technology is simple and convenient, cost is low, manufacturing is simple and convenient, and its appearance quality is good simultaneously, the peculiar granule pore of foundry goods appearance can not occur, be not prone to the quality problems of leaking, the yield rate height yet; It decorates overcoat also can be mixed with various moulding style, the various styles attractive in appearance of conversion are more or less freely, its body interior structure can adopt harmful element made such as stainless steel or other be not leaded, more effectively fundamentally solved the water tap that directly contacts that traditional cast copper makes a difficult problem, met the high standard environmental requirement of the national strict observing and controlling in USA and Europe because of leaded polluted water with water; Be suitable for producing in enormous quantities.
