Description

Improved faucet

Technical field

It the utility model is related to a kind of improved faucet.

Background technology

Water inlet pipe and outlet pipe known, that existing tap includes valve body, connected with valve body, current enter from water inlet pipe Valve body flows outwardly after the spool in valve body from outlet pipe.The known tap valve body and spool generally using brass or Kirsite integrally casting shaping, manufacturing technique requirent is higher during casting, and process is complicated, and contains a poisonous huge sum of money in founding materials Belong to lead chemical analysis, do not reach requirements of the national standard, be unfavorable for environmentally protective, the health of the mankind is affected;In addition all It is made of more metal materials, materials are of high cost, and metal pipelined channel anti-corrosion effect is bad, the long influence water quality mouth of usage time Sense.

In order to solve the above-mentioned technical problem, China Patent No. is：201420488167.2 disclose a kind of modified split Tap, including kirsite valve chest and the plastic valve core print seat being set in kirsite valve chest, the lower end of the plastic valve core print seat Equipped with for the cylindrical type thread bush through wash platform mounting hole, the matched locking nut of screw thread is configured with outside the thread bush, Modified split tap is installed using plastic valve core print seat (plastic inner pipe) and kirsite valve chest (metal shell) Split assembled Form, easy to manufacture, when casting reduces manufacturing technique requirent, simplifies processing technology, saves cost of labor, improves life Efficiency is produced, while it is bad to solve metal inner surface anti-corrosion effect, the problem of usage time long influence water tasting, but this changes Into type tap, still there are following defect in use：

1st, for its shell body of L-type tap when being integrally formed, the most complicated part of its technique is the end of outlet pipe, existing Have in technology, not only mould is complicated, materials are of high cost, but also processing and its inconvenience；

2nd, above-mentioned tap is through type, its housing and plastic valve core print seat are homogeneous body formed therefore easy to assembly, still It is for L-shaped tap（Faucet body and the perpendicular setting of outlet pipe）It can not be used；

3rd, the inner core of water flowing uses plastic valve core print seat, and plastic inner pipe is influenced by cold air or cold water source, can become at low temperature It is crisp, because plastic inner pipe can hot account shrinkage, easily overhanged crackle when hydraulic pressure is unstable, the phenomenon of bursting by freezing occur, service life is extremely short, Weather tremble with fear jelly local applicability it is not strong；After the kirsite valve chest and the installation of plastic valve core print seat, there is gap between the two, two Gap between person has wet air or because the moisture after plastic valve core print seat bursting by freezing flows into, and kirsite housing is main Composition is kirsite, is amphoteric metal, poor chemical stability, is very easy to oxidation, corrosion, service life in wet air It is and very limited.
