Description

Column-type water tap and manufacture method thereof

Technical field

The present invention relates to a kind of column-type water tap, and the manufacture method of this column-type water tap.

Background technique

As shown in Figure 1, the column-type water tap of Xiao Shouing comprises leading main casing in the market, the tap main casing is generally by spool fixed cover body 52, the spool base, cylindrical jacket pipe 51, water inlet body and water outlet body constitute, cylindrical jacket pipe 51 is generally made with seamless steel pipe, perhaps adopt the founding cast, wherein spool fixed cover body 52 adopts the manufacturing of founding casting technique to be shaped, and be aided with the turning shape, adopt turning process to obtain internal thread in the valve core housing body, valve seat adopts the founding casting technique equally and is aided with the turning shape, again on valve seat boring form cold and hot intake tunnel and and exhalant canal, wherein spool fixed cover body 52 and spool base are welded in the cylindrical jacket pipe 51, offer the through hole of aiming at exhalant canal on the cylindrical jacket pipe 51, the port that the water outlet body is aimed at exhalant canal is welded on the cylindrical jacket pipe 51, and the warm-cold inleting pipe body is welded on the port of cold and hot intake tunnel.The shortcoming of existing column-type water tap is as follows: 1, cylindrical jacket pipe 51 general employing seamless steel pipe manufacturings in the said structure, perhaps adopt the technology manufacturing of founding casting, because the market price of seamless steel pipe is higher, thereby improved the cost of material of product, and seamless steel pipe is to stretch and annealing process is made through multiple tracks, so toughness is relatively poor, and the glossiness of appearance is also bad, and the manufacture cost of founding technology is higher, also can cause the rising of product cost; 2, also need to offer in addition through hole on this outer sleeve, and aligned through holes is welded the water outlet body on cylindrical jacket pipe 51, therefore technology is comparatively complicated, processing cost is also high, the joint fastness of water outlet body and outer sleeve is relatively poor, and 3, the founding casting technique troublesome poeration that adopts of spool fixed sleeving and valve seat, the cost of labor that expends is higher, the flowing water vias inner walls that forms is very coarse, accumulates dirt easily; 4, the gimmick that adopts boring to form the exhalant canal on the valve seat generally need be passed through following operation: at first adopt vertical boring and do not bore saturating, boring cross-drilled hole then between two cold/hot water passages converges with vertical hole, but the cold and hot intake tunnel of column-type water tap is general and exhalant canal is very close, therefore be easy to bore broken cold and hot intake tunnel, technological requirement to boring is very high, and the reject rate that causes is higher.

Summary of the invention

Technical problem to be solved by this invention provides a kind of column-type water tap, and the manufacturing process of this column-type water tap is simple, and the cost of material and the cost of labor that expend are relatively low.The present invention also will provide a kind of manufacture method of column-type water tap, and this method is simple to operate, and the cost of labor that expends is lower.

For this reason, column-type water tap provided by the invention comprises leading main casing, the tap main casing comprises leading main casing, the tap main casing comprises outer sleeve, the water inlet body, water outlet body and valve seat, valve seat is fixed on the top in the outer sleeve, have water inlet and osculum on the valve seat, water inlet body upper end is aimed at the water inlet and is connected with valve seat, one end of water outlet body is aimed at osculum and is connected with valve seat, the other end of water outlet body sees through the tube wall and the outside conducting of outer sleeve, the sidepiece of outer sleeve offers through hole, water outlet body and outer outlet pipe body in the water outlet body comprises, one end of interior water outlet body is aimed at osculum and is connected with valve seat, and the other end aligned through holes of interior water outlet body is connected with outer sleeve, and an end aligned through holes of outer outlet pipe body is connected with outer sleeve.

For this reason, the present invention also provides the manufacture method of above-mentioned column-type water tap to comprise A, form outer sleeve with the sheet metal bending and in its dual-side butt welding; B, sheet metal is made valve seat with the interior circle coupling of outer sleeve, valve seat is welded on the inwall of outer sleeve; C, prefabricated water inlet body, with the upper end of water inlet body aim at water inlet and valve seat welding on the valve seat, the lower end of water inlet body is to the extension of the lower end of outer sleeve; D, prefabricated interior water outlet body and outer outlet pipe body, weld with the osculum on the end aligning valve seat of interior water outlet body and with valve seat, with in the through hole of the insertion outer sleeve sidepiece of interior water outlet body and with the outer sleeve welding, an end aligned through holes of the outer outlet pipe body outer wall with outer sleeve is welded; E, on the inwall of outer sleeve above the valve seat in a tubular form internal thread sleeve pipe of welding, have internal thread on the internal thread sleeve pipe; F, the leading main casing that completes in the above-mentioned steps installed the parts of the formation water tap of other manufacturing.

Because the leading main casing of column-type water tap provided by the invention comprises outer sleeve, the water inlet body, water outlet body and valve seat, wherein valve seat is fixed on the top in the outer sleeve, water inlet body upper end is aimed at the water inlet and is connected with valve seat, one end of water outlet body is aimed at osculum and is connected with valve seat, the valve seat that only needs only to have water inlet and osculum when therefore making water tap of the present invention is fixed on the inwall of outer sleeve, originally only need to be connected with valve seat respectively and can to obtain with the water outlet body with exhalant canal with the intake tunnel that valve seat is structure as a whole with the water inlet body, the structure of water tap of the present invention directly causes having the technology that intake tunnel and exhalant canal parts needn't adopt the founding casting, and the cost of labor that this traditional founding casting technique often expends is very high, in the present invention valve seat only need with the sheet metal stamping-out and on sheet metal stamping-out water inlet and osculum can be shaped, technology is very simple, intake tunnel and exhalant canal all form in water outlet body and water inlet body in addition, the thickness of tube wall can be reduced greatly, saved cost of material.
