Description

Water tap plastic cement control valve

Technical field

The utility model belongs to supply channel joint technical field, relates in particular to a kind of water tap plastic cement control valve.

Background technique

Members such as the body of traditional water tap and water outlet, mostly be made by copper material or cast member etc., not only manufacture cost is higher, and because the area of contact of copper or other metal casting part and water is bigger, the leaded material that waits heavy metal etc. to have toxicity in the water takes place easily, so countries such as the U.S. and Europe, begun the lead tolerance of sanitaryware is strict with, so the lead tolerance that how to reduce sanitaryware has been the significant problem that the sanitaryware manufacturer is faced to meet American-European standard.

To this, there is the dealer to research and develop for installing flexible pipe in the depotition cock reducing the structure of water and copper or metal construction area of contact, as: No. 7415991 patent of U. S. Patent promptly is.This patent mainly is at the inner formation of metal water tap chamber, a flexible pipe to be set in wherein, the two ends of flexible pipe connect an inlet connection piece and an outlet connection piece respectively, and flexible pipe, inlet connection piece and outlet connection piece all are by the non-metallic material manufacturing.Thus, the member that contacts with water all is that non-metallic material is made, can reach the standard of water safety thus.

Yet the technology that this patent disclosed only is to apply to depotition cock, because general depotition cock is arranged on the downstream side of water control valve, therefore the hydraulic pressure that is born is less, more easily reaches on fixing and anti-leak.But if use members such as water control valve and pipe joint thereof instead the plastic cement material goods all, then tradition will face the test of certain degree with the technology of thread locking leakproof on fixing and anti-leak.

On the other hand, it is comparatively inconvenient the thread of each pipe joint being locked in the screw.Because the space of water control valve bottom is narrow and small, when assembling, must stretch into the spanner side direction and progressively lock each joint in the narrow space and need expend the more time, add two joints of the generally essential connection of water control valve, supply the hot water or cold water respectively, sometimes even can connect another titting water outlet, this action that will cause locking will repeat two, three times, generally speaking, such assembling mode is comparatively time-consuming, bothersome.

Moreover flexible pipe is normally made with the soft material with preferable ductility, so the junction point of flexible pipe and inlet connection piece or outlet connection piece, produces problems such as loosening, leakage easily because of the variation of hydraulic pressure, therefore still has in addition improved necessity again.
