Description

Column-type water tap

Technical field

The present invention relates to a kind of water tap column-type water tap.

Background technique

The water flow inside control unit of the faucet valve core of the appearance that occurs in the market generally compresses through being arranged at the fixed block that is threaded with valve seat on the water tap; Thereby avoid fixed valve plate and moving valve plate to cooperate defective tightness and leak; But the fixed block of the water tap of this structure must be installed on the valve seat of leading main casing; Stressed position is all in the valve seat position; When adopting makings such as the relatively poor material of intensity such as synthetic quartz, glass when leading main casing often quality can not reach a standard, cause the water tap valve seat position to be ruptured easily.The hydraulic pressure test for water tap is even more important in the manufacture process of water tap in addition; General this test need be carried out when the water tap installation; If can only splitting, test failure reinstalls test, so the efficient extreme difference, and the water tap of testing often all is the finished product water tap of handling through surface lacquer, plating etc.; When carrying out hydraulic pressure test, be easy to take place grazing, cause faucet surface to be damaged.

Summary of the invention

Technical problem to be solved by this invention provides a kind of column-type water tap, and the strength of materials of the valve seat part of this water tap requires low, can make water tap adopt more new material manufacturing.

For this reason, column-type water tap provided by the invention comprises leading main casing, has valve seat on the leading main casing, and valve seat is provided with faucet valve core; Faucet valve core comprises spool housing and current control unit, and the current control unit is placed in the spool housing, and spool housing upper end offers mounting hole; The spool housing is equipped with fixed block, and fixed block is threaded with the spool housing, the current control unit in the fixed block pressed spool housing; Faucet valve core disposes trim, and the valve seat bottom offers placement hole, and spool housing lower end has into water connecting tube; The water inlet connecting tube passes placement hole and is connected with external water pipe, has block board around the placement hole on the valve seat, and faucet valve core is inserted by leading main casing upper end; The faucet valve core bottom is stuck on the block board, and water tap is the water tap with cold and hot water outlet, is arranged at the importing cold water of spool housing lower end and two water inlet connecting tubes of hot water and is arranged in the fixed tube jointly; Fixed tube is equipped with fixed plate, and fixed plate is provided with the tapped hole that supplies fixed tube to pass, and the fixed tube outside has the outside thread with this tapped hole coupling; Fixed plate is threaded with fixed tube, and inboard, leading main casing bottom has the screens step, and fixed plate is stuck on the screens step; Fixed plate and valve seat are with the tension of spool housing, and fixed tube is extended outside the leading main casing, and is equipped with the retainer ring that is threaded with it.

Because the fixed block of faucet valve core provided by the invention can directly be threaded with the spool housing of faucet valve core; Current control unit in the fixed block pressed spool housing, so the force bearing point that fixed block is used for the pressed spool assembly all comes from the spool housing, faucet valve core has formed an assembly that can bear hydraulic pressure separately; Can faucet valve core be carried out hydraulic pressure test separately; Be installed to after the test on the water tap, water tap carries out surface treatment more again, thus re-assemblying of can not occurring causing because of hydraulic pressure test is defective; Therefore working efficiency is higher, and grazing faucet surface when not worrying testing.And because water tap valve seat is no longer stressed, but the materials such as adopting the relatively poor crystal more attractive in appearance of intensity, glass or plastics of therefore having ready conditions is made whole water tap.
